Most ordinary paper-plastic packaging can only hold liquid contents, and the types of contents that can be held are single; Roof-type packaging requires multiple steps to open and is inconvenient. Moreover, due to the influence of the two inner folding corners, a larger opening cannot be opened. And because its top surface is roof-shaped, the top cannot directly bear pressure during transportation. There are also processing methods. The limitations of the packaging make it unable to contain contents other than liquids; the packaging of the tear-off aluminum foil main seal area requires repeated folding of the aluminum foil before it can be torn open, which is a cumbersome step; the traditional liquid food can packaging, the eight-treasure porridge cans on the market, due to their cylindrical shape Due to its shape, the transportation cost is higher than that of a rectangular package. It also has a lid to accommodate the spoon. It cannot be sealed and cannot ensure the health and safety of the spoon. It cannot be connected to the package. It is also made of a different material than the packaging body, and has a greater impact on the environment. Large; glass can packaging is large in size, heavy, fragile, and inconvenient to carry; plastic soft packaging for condiments has poor ability to stand on a flat surface, and the packaging texture is soft so that it is inconvenient to pour out.

In the existing technology, the processing technology for food packaging with inward folding corners, such as roof-type packaging structures, is too complicated, requires multiple processes, and requires two or three sets of equipment to complete the entire process of processing and filling, which is time-consuming, labor-intensive, and difficult to operate. It is inconvenient and has low production efficiency; and due to the order of filling first and then cornering in the existing technology, contents with large internal friction resistance and poor fluidity are not compatible with this type of packaging.

In summary, various types of packaging are the main domestic waste in the world, and consumer demand is getting higher and higher. It is necessary for technicians in this field to provide a kind of packaging that is highly compatible, easy to use, hygienic and environmentally friendly, and has low transportation costs. packaging, and a processing equipment that overcomes process conflicts, facilitates processing, and has high production efficiency.

Compared with traditional processing equipment and methods, the processing equipment and processing methods provided in the embodiments of the present application can process inward corners on the packaging structure from the perspective of packaging. The packaging structure with inward folds can be used by users. The inner folding corner opens the package, thus providing users with another option besides cutting the package. Moreover, by opening the seal from the inner folding corner, the main seal of the packaging structure can be completely unsealed without tools, which is convenient and labor-saving, or it can open a repeatable Use the pour spout. This packaging is used to contain products that are in a semi-solidified state after cooling, such as pre-made vegetable products. Compared with the existing technology packaging in which the aluminum foil is the upper sealing area, the entire main sealing area needs to be opened by repeatedly folding and then tearing off. The inner folded corner can be used to unseal the complete upper sealing area in one step, which will not generate additional waste, and can open the entire upper sealing opening in one step, which is more labor-saving and convenient, catering to the needs of consumers; use this package to contain liquid food products that are half liquid and half granular. For example, for products such as rice pudding porridge, compared with the existing technology, traditional rice pudding porridge can packaging products, in terms of transportation costs, under the same space conditions, the square packaging must contain a larger volume than the cylindrical packaging. From the perspective of packaging function, the opening of this package is an oblique opening, which not only has a larger cross-section, but is also more conducive to pouring out the contents. From an environmental perspective, if there is a cavity in the inner wall of this package for isolation and Storage of accessories such as spoons, compared to can packaging, can reduce the waste of a plastic cover used to hold spoons; when using this packaging to contain solid particulate products, such as cumin, spices and other condiment products, compared to the existing Glass bottle packaging or flexible packaging. When going out for a picnic or other scenes, this packaging can form a small diagonal opening for pouring by pulling out the inner corner. It can stand on the table like a glass bottle packaging or like a soft packaging. It is equally lightweight, and when the customer has not finished using it, he or she can stuff the inner corner of the package back into the package to form a moisture-proof, semi-sealed package that is convenient for reuse next time and has the feature of being reusable; use this package When holding liquid products, such as milk and other drinks, you can choose to pull out the inward folding corners to form a small opening, or open the entire upper seal through the inward folding corners. These two opening methods of the inward folding corners can give customers more opening options. There are some examples of packaging opening methods, such as the opening on the inside of the outer folding corner on the opposite side of the inner folding corner. It is possible to uncover the folding corner in one step and drive the packaging opening to break, which is labor-saving and concise. In addition, for packages with a single inner folding corner, the top of the package is diagonally The opening results in a larger outer folding angle on the opposite side of the inner folding angle, which is conducive to the setting of the side pouring outlet. There is also an embodiment of a built-in straw located at the inner folding corner, which can ensure the integration of garbage and reduce the harm of straws to the environment. It also has The function of re-storing the straw realizes the hygiene problem of multiple uses.

From the perspective of processing technology, the above-mentioned processing equipment and processing methods are used to process the packaging structure, which is easy to operate and has a high degree of automation. For example, the above-mentioned integrated processing equipment and processing methods can complete the integrated processing of the packaging structure through a complete set of equipment. The above-mentioned processing equipment and processing methods can process two connected packaging materials at the same time, which can greatly improve work efficiency and reduce the degree of manual participation, thereby reducing worker labor intensity and production costs; or such as the above-mentioned split processing equipment and processing methods , processing a single packaging material, by first making the inner folding corner of the packaging and sealing the lateral opening at the top of the packaging to form a fillable packaging body, and then filling the product through the bottom surface of the packaging. The benefits of this processing method are: First of all, for products such as solid particles, half-liquid and half-granular liquid foods, or semi-solidified products with large internal friction resistance and poor fluidity, if the existing technology is used, the product must be filled first and then the inner folds can be made. And sealing the main seal on the top of the package, it is difficult to process the inward corner packaging with high yield rate. However, by changing the processing sequence, this processing method can overcome the problem of large friction resistance and low fluidity in filling materials and manufacturing of such products. Secondly, due to the single inner folding corner packaging, most of the packages before forming have an oblique upper opening, which is not conducive to filling. Therefore, the inside of the belt needs to be processed first. Open one end of the folded corner, and then fill from the other end of the package.

Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this application.

In order to enable those skilled in the art to better understand the solution of the present application, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

It should be noted that the directional terms such as "upper end, lower end, left side, right side" described below are all defined based on the drawings of the description.

The processing equipment provided by the embodiment of the present application is used to process the packaging structure 100. The processing equipment includes a pre-processing module 1, a three-dimensional forming module 2, an angle-making module 3 and a post-processing module 4. The pre-processing module 1 is used to process the packaging structure 100. The packaging material is pre-processed to make the packaging material into a foldable packaging body; the three-dimensional forming module 2 is used to form the foldable packaging body into a three-dimensional packaging body; the corner-making module 3 is used to form the inner folding corner 101 on the three-dimensional packaging body; and then The processing module 4 is used for post-processing the cornered three-dimensional packaging body to form the packaging structure 100 .

It should be noted that the above-mentioned three-dimensional packaging body is specifically a tubular packaging body. The preprocessing module 1 may also include the manufacturing steps of packaging materials, such as the multi-layer composite manufacturing steps of packaging materials, surface printing steps of packaging materials, through-hole and re-sealing steps. The three-dimensional forming module 2 is used to form a tubular three-dimensional packaging body structure that is transparent from top to bottom.

Further, the angle-making module 3 includes a support module 31, an outer angle module 32 and an extrusion sealing module 33. The support module 31 is provided below the three-dimensional molding module 2, and the support module 31 is used to receive the three-dimensional molding module 2. The three-dimensional packaging body on the packaging body is used to support the three-dimensional packaging body; the outer angled module 32 is arranged toward the support module 31, and the outer angled module 32 is used to embed the three-dimensional packaging body to form a preformed inner folding structure on the three-dimensional packaging body; The extrusion sealing module 33 is used to squeeze the three-dimensional packaging body to make the preformed inner fold structure into a fixed inner fold structure, and to seal and fix the fixed inner fold structure.

It should be noted that the preformed inner fold 101 means that the inner fold 101 already has a structure, but the inner fold 101 has not been shaped by a sealer. In fact, the support module 31 is a master mold for the product, and the outer angled module 32 is a sub-mold. The essence of the angle-making process is the mold closing process.

Compared with traditional processing equipment and methods, the processing equipment and processing methods provided by the embodiments of the present application, from the perspective of packaging, have a packaging structure 100 with an inner folding corner 101, which allows users to open the package from the inner folding corner 101, thereby Provide the user with another option besides cutting the package, and open the seal from the inner folding corner 101. The main seal of the packaging structure 100 can be completely unsealed without tools, which is convenient and labor-saving, or a reusable pouring outlet can be opened. . This package is used to contain products that are in a semi-solidified state after cooling, such as pre-made dish products. Compared with the existing technology packaging in which the aluminum foil is the upper sealing area, the entire main sealing area needs to be opened by repeatedly folding and then tearing off. The inner folding corner 101 can unseal the complete upper sealing area in one step, which will not generate additional waste, and can open the entire upper sealing opening in one step, which is more labor-saving and convenient, catering to consumers' consumption needs; use this package to hold half liquid and half granular liquid food When it comes to products, such as rice pudding porridge and other products, compared with the existing technology, traditional rice pudding porridge can packaging products, in terms of transportation costs, under the same space conditions, the square packaging must contain a larger volume than the cylindrical packaging. , from the perspective of packaging function, the opening of this package is an oblique opening, which not only has a larger cross-section, but also is more conducive to pouring out the contents. From an environmental perspective, if there is a cavity in the inner wall of this package for isolation With accessories such as storing spoons, compared to can packaging, it can reduce the waste of a plastic cover used to hold spoons; when using this packaging to contain solid particulate products, such as cumin, spices and other condiment products, compared to existing It is a glass bottle packaging or soft packaging. When going out for a picnic or other scenes, this packaging can form a small oblique opening for pouring by pulling out the inner folding corner 101. It can be stood on the table like a glass bottle packaging. It is as light as flexible packaging, and customers can stuff the inner folded corners 101 back into the packaging before using it up to form a moisture-proof semi-sealed packaging form, which is convenient for reuse next time and has the characteristics of multiple uses; When using this package to hold liquid products, such as milk and other drinks, you can choose to pull out the folded corners to form a small opening, or open the entire upper seal through the folded corners 101. These two opening methods of the folded corners 101 can give customers more openings. There are also some examples of packaging opening methods, such as the opening on the inside of the outer folding corner 102 on the opposite side of the inner folding corner 101, which can realize the one-step opening of the folding corner to drive the packaging opening to rupture, which is labor-saving and simple, and has a single inner folding corner 101. Packaging, the top of the package is an oblique opening, resulting in a larger outer folding corner 102 on the opposite side of the inner folding corner 101, which is conducive to the setting of the side pouring outlet, and there is also an embodiment of a built-in straw 122 located at the inner folding corner 101, which can ensure the integration of garbage , reducing the harm caused by the straw 122 to the environment, and also has the function of re-storing the straw 122 to realize the hygiene problem of multiple uses.

From the perspective of processing technology, processing the packaging structure 100 through the above-mentioned processing equipment and processing methods is easy to operate and has a high degree of automation. For example, the above-mentioned integrated processing equipment and processing methods can complete the integrated processing of the packaging structure 100 through a complete set of equipment. , using the above processing equipment and processing methods, two connected packaging materials can be processed at the same time, which can greatly improve work efficiency and reduce the degree of manual participation, thereby reducing worker labor intensity and production costs; or such as the above-mentioned split processing equipment and The processing method is to process a single packaging material by first making the inner folding corner 101 of the packaging and sealing the lateral opening at the top of the packaging to form a fillable packaging body, and then filling the product through the bottom surface of the packaging. This processing method The advantages are: first of all, for products such as solid particles, semi-liquid and semi-granular liquid foods, or semi-solidified products with large internal friction resistance and poor fluidity, if the existing technology is used, the product must be filled first, and then It is difficult to process the inner folded corner 101 package with a high yield by making the inner folded corner 101 and sealing the main seal on the top of the package. However, by changing the processing sequence through this processing method, this type of product with large friction resistance and low fluidity can be overcome. The defect is the process conflict between the filling material and the corner making. Secondly, due to the 101-style packaging with a single inner corner, most of the packages before forming have an oblique upper opening, which is not conducive to filling. Therefore, it is necessary to process the opening at one end with the inner folding corner 101 first, and then fill the opening from the other end of the package.

The following is a detailed description of two different processing equipment.

For the first processing equipment:

In some embodiments, the three-dimensional forming module 2 is connected to the support module 31, and the number of packaging materials is two. The two packaging materials are connected, and the two packaging materials are centrally symmetrical about the connecting line between the two. Or two The packaging material is arranged in mirror symmetry with respect to the connecting line between the two. That is to say, two packaging materials are one processing unit, and the processing units are connected end to end.

In this embodiment, the first processing equipment can process two connected packaging materials at the same time, which can improve work efficiency to a certain extent. When the two packaging materials are arranged centrally symmetrically about the connecting line between the two packages, that is, the positions between the inner folding corners 101 of the two packages are on opposite sides, the utilization rate of the packaging materials is the highest, but the cost of the packaging machine is relatively high. ; When two packaging materials are arranged in mirror symmetry with respect to the connecting line between the two, that is, the inward folding angles 101 of the two packages are on the same side, the structure of the packaging machine is relatively simple and the machine cost is relatively low, but The cost of a single package increases and the utilization rate of packaging materials decreases, because there will be a certain amount of packaging material waste area generated between the top main sealing areas of the two packaging materials. You can choose to wrap materials in this area when the sealer is sealing. Cut off, but if this area is slightly utilized, such as processing this area into an integrated packaging handle 124, it can also meet the needs of consumers.

In some embodiments, the support module 31 includes a fixed support unit 311 and a movable support unit 312, wherein the fixed support unit 311 is connected to the three-dimensional forming module 2, and the fixed support unit 311 is used to support at least a part of the three-dimensional packaging body; the movable support unit 312 Movably provided on the three-dimensional forming module 2, the movable support unit 312 is used to cooperate with the outer angled module 32 to form a preformed inner corner structure on the three-dimensional packaging body.

Specifically, the lateral size of the three-dimensional molding module 2 is not less than the lateral size of the fixed support unit 311, wherein the top of the fixed support unit 311 is connected to the bottom of the three-dimensional molding module 2, and the left end surface of the fixed support unit 311 is connected to the three-dimensional molding module 2. The left end surface of the module 2 is flush, and both are distributed in the vertical direction; the top of the movable support unit 312 is rotatably located at the bottom of the three-dimensional forming module 2 .

In addition, the processing equipment also includes a control module 5 , which is used to control the movement of the movable support unit 312 relative to the three-dimensional forming module 2 .

In some embodiments, the movable support unit 312 is specifically a metal plate, and the control module 5 is specifically an electromagnet module. After the electromagnet module is powered on, it uses magnetic attraction to absorb the metal plate to support and clamp the three-dimensional packaging body.

It can be understood that after the packaging body is placed on the support module 31, the control module 5 controls the movable support unit 312 to swing in a direction away from the fixed support unit 311 to tighten the three-dimensional packaging body. After that, the outer angled module 32 Moving toward the support module 31, the outer angled module 32 is embedded into the three-dimensional packaging body to form a preformed inner corner structure on the three-dimensional packaging body. Of course, the control module is responsible for controlling the mold closing action of the corner control unit, and also needs to be responsible for controlling the return initial position of the corner control unit to release the finished packaging body and move it to the next process.

Of course, according to actual needs, the molding of the preformed inner angled structure requires the close cooperation between the outer angled module 32 and the movable support unit 312, and according to the preformed inner angled structure, corresponding grooves can be provided on the movable support unit 312. When the outer cornering module 32 is embedded in the groove, the preformed inner corner structure can be imprinted on the packaging body, and then you can choose to release it and make the corners again, mainly to prevent the corners from conflicting with the packaging machine; or Release after cornering.

In some embodiments, the extrusion sealing module 33 includes a side extrusion unit and a first sealer 332 , wherein the side extrusion unit is disposed toward the support module 31 and is used for extruding the preformed inner folded corner structure. The inner folded corner structure is formed and shaped; the first sealer 332 is connected to the side extrusion unit, and the first sealer 332 is used to seal and fix the inner folded corner structure.

After the preformed inner folded corner structure is formed on the packaging body, the preformed inner folded corner structure is extruded through a side extrusion unit to form a fixed inner folded corner structure, and then the fixed inner folded corner structure is sealed and fixed by the first sealer 332 .

It should be noted that the sealer should seal and fix the edge position of the main sealing area of the package including the side with the inner fold corner, that is, the incision position of the packaging processing unit after the inner fold corner is folded in, so that the tubular packaging processing units are connected end to end. Sealed, in a fillable sealed cavity, eliminating the influence of previous incisions.

In some embodiments, the preprocessing module 1 includes an indentation unit 11, a longitudinal sealer 12, a cutting and processing unit 13 and/or an accessory adding unit, wherein the indentation unit 11 is used to form indentations on the packaging material; The sealer 12 is used to seal the longitudinal sealing area of the packaging material; the accessory adding unit is located between the creasing unit 11 and the three-dimensional forming module 2, and the accessory adding unit is used to add accessories (such as soup spoons, etc.) to the packaging material; the incision The processing unit 13 is provided between the creasing unit 11 and the three-dimensional forming module 2, and is used to form positional cuts 128 of the preformed inner folded corner structure on the packaging material. The incision and processing unit 13 also includes a glue spraying module. For the inner folding corner 101 area of the longitudinal inner folding corner 101 package, all the glue can be sprayed, because the main seal bears the packaging pressure, and the inner folding corner 101 area only needs to ensure the sealing performance, which is preferred. , use food grade hot melt glue. Of course, the sealer mentioned above is not limited to heat sealing machine or ultrasonic sealing machine. For the processing situation of full glue spraying at the longitudinal inner folding corner 101, the sealing module of the inner folding corner 101 only needs to apply pressure to make the built-in layer The two triangular pieces 117 are closely connected.

It should be noted that only the single-roof-type inner folding corner 101 package processed on the same side or the double-roof type inner folding corner 101 package of the prior art can directly make the inner folding corner 101 of the package through the corner-making module 3 without using the cutting unit.

It should be noted that when vertically processing double inner corner 101 packaging, two packaging materials are used as one processing unit, and two methods can be used. One is as shown in Figure 6, which is to directly manufacture the packaging without using the incision and processing unit 13. Corners require two steps. The first step is to make the corners and then release them to the next step. The second step is to fix the inner folded corners 101. The lower set of the corner making modules 3 in the second step must be missing, otherwise it will not work. Sealing the main sealing area 103; the second method, as shown in Figure 7, uses the incision and processing unit 13 to first cut the incision 128, then fold the inner corner 101, and then seal the main sealing area 103 and the inner corner through the outside of the package. 101 sealing area. Compared with the previous processing method, this method has one less corner-making module 3, but will produce an additional packaging waste area. It is preferable to provide a solution for sealing and cutting the remaining material area. Hand 124 shape.

In some embodiments, the post-processing module 4 includes a filling tube 41 and a main sealing and cutting device 42, wherein the filling tube 41 is used to fill the content into the cornered three-dimensional packaging body; the main sealing and cutting device The cutter is located below the corner-making module 3. The main sealing cutter is used to seal the main sealing area 103 of the filled three-dimensional packaging body and cut the three-dimensional packaging body. At the same time, it can also be used to seal the main sealing area 103 of the three-dimensional packaging body after filling. The sealing area 108 is modified. For example, when the inner corners 101 of two packages are on the same side, there will be a large waste area in the main sealing area on the top of the two packages. The packaging handle 124 can be cut out in this area to provide Use required. In addition, because one main sealing area is oblique in some embodiments, when the package has sealing areas and cutting lines in two directions, two sets of horizontal sealers can be provided to seal and cut respectively.

For the second processing equipment:

In some embodiments, the three-dimensional forming module 2 and the support module 31 are not connected, and the packaging material is a single packaging material. In other words, the second type of processing equipment is mainly used for processing a single packaging material, and a single packaging material is a processing unit. In other words, compared to the first type of vertical integrated processing and filling, which can be called integrated processing equipment and technology, the second type is split processing equipment and technology with each step separated.

In some embodiments, the pre-processing module 1 includes a creasing unit, a cutting unit, a folding unit, a sealing unit, a stacking unit 14 and a suction cup unit 15, where the creasing unit and the cutting unit are used to form a film on the packaging material. Indent and cut out the packaging materials; the folding unit and the sealing unit are used to fold the packaging materials, and the folding unit and the sealing unit are used to seal the longitudinal sealing area of the packaging materials; the stacking unit 14 is used to stack the completed Cut and flat packaging materials; the suction cup unit 15 is provided between the stacking unit 14 and the three-dimensional forming module 2. The suction cup unit 15 is used to suck packaging materials from the stacking unit 14 and transfer the packaging materials to the three-dimensional forming module 2 superior.

It should be noted that the creasing unit and the cutting unit perform the functions of creasing and cutting out packaging unit materials respectively; similarly, the folding unit and the sealing unit perform the functions of folding packaging materials and sealing the packaging body respectively. The function of the longitudinal sealing zone. These four functional units can arrange the sequence of the process flow according to the actual situation. The terms mentioned in this case do not necessarily require or imply any such actual relationship or sequence between these functional units.

In the preprocessing process, an indentation is formed on the packaging material through the creasing unit and the cutting unit, and the packaging material is cut out, and then the longitudinal sealing area of the packaging material is sealed through the folding unit and the sealing unit. The cut and flat packaging materials are stacked on the stacking unit 14. Finally, the packaging materials are sucked from the stacking unit 14 through the suction cup unit 15, and the packaging materials are transferred to the three-dimensional forming module 2. Further, the three-dimensional forming module 2. Shape the flat packaging material into a three-dimensional packaging body.

It should be noted that the vertical processing method can be used to first indent and then add accessories, and then cut the packaging body to form a folded and flat packaging body, which can be stacked and then stacked on the unit; or in the second processing sequence, Each packaging body is first indented and then cut, and then the longitudinal sealing line is sealed and then folded; of course, other processing sequence arrangements and combinations are also possible.

In some embodiments, the processing equipment further includes a track 6. The support module 31 and the outer angled module 32 are independently arranged on the track 6 and can move along the track 6.

Specifically, the track 6 is provided with a first track area 61 and a second track area 62. The running speed of the support module 31 and the outer angled module 32 in the first track area 61 is higher than that in the second track area 62. speed. It should be noted that when the first track area 61 is running, the support module 31 and the outer angled module 32 run with a distance between them; when the second track area 62 is running, the support module 31 and the outer angled module 32 are running. They are brought together and run to realize that the support module 31 and the outer angled module 32 are molded together to form a preformed inner angled structure on the three-dimensional packaging body.

It should be noted that the first track area 61 is located on the front side, and the second track area 62 is located on the rear side. In this way, the support module 31 and the outer angled module 32 first run with a distance between them, and then move to the second track area. At 62 o'clock, the support module 31 and the outer angled module 32 are brought together and run. The purpose of bringing the support module 31 and the outer angled module 32 together is to form a preformed inner angled structure on the three-dimensional packaging body after the support module 31 and the outer angled module 32 are molded together. Here, the support module 31 can be understood as a mother mold, and the outer angled module 32 can be understood as a sub-mold. Through the mold closing movement of the sub-mold relative to the mother mold, a preformed inner corner structure is formed on the three-dimensional packaging body. Of course, the speeds of the first track zone and the second track zone should not differ too much, otherwise there will be too much accumulation in the second track zone. Furthermore, the second track area is an indirect power operation area of a certain length. When the first track sends a group of corner-making modules into the entrance end of the second track, the corner-making modules collide with the previous group and push the previous group. The group is pushed forward again, so that the group closest to the exit end of the second track area is pushed out from the exit end, enters the active power operation area, and runs to the next process.

In some embodiments, the extrusion sealing module 33 includes a second sealer 334 and two extrusion bars 333 , wherein the two extrusion bars 333 are disposed in the second track area 62 , and the two extrusion bars 333 The spacing is tapered in the direction away from the three-dimensional forming module 2; the second sealer 334 is provided in the second track area 62, and the second sealer 334 is used to seal the fixed and shaped inner folding corner structure and the main seal. It should be noted that the extrusion strip 333 serves as a guide, so that when the package moves toward the sealer, the main seal and the sealing opening of the inner folding corner 101 become smaller and smaller.

In some embodiments, the above-mentioned track 6 is an annular track 6. The support module 31 and the outer angled module 32 are independently arranged on the annular track 6 and can move along the annular track 6. The support module 31 and the outer angled module 32 The drive module can be set up separately for driving, and the drive module can be a power motor component, etc.

In addition, in order to facilitate mold ejection, the support module 31 is provided with an automatic mold ejector 7. When the support module 31 runs below the annular track 6, the automatic mold ejector 7 relies on gravity to extend the support module 31, so that the corner making and sealing can be completed. The closed three-dimensional packaging body is separated from the support module 31; when the support module 31 moves above the annular track 6, the automatic mold ejector 7 automatically returns to its position by gravity.

Furthermore, the processing equipment also includes a baffle 8, which is set toward the annular track 6. The baffle 8 is used to allow the cornered and sealed three-dimensional packaging body to separate from the support module 31 at a preset position, or to ensure automatic withdrawal. The mold 7 returns to its original position before entering the next round of processing position. The baffle 8 is provided at the bend position of the circular track 6 . It should be noted that the baffle is used to ensure that the mold ejector ejector is at the appropriate position and returns to the initial position at the appropriate position.

In some embodiments, the post-processing module 4 includes a Z-shaped track 43, a receiving car 44, a filling unit 45 and a side extrusion and continuous sealing unit 46, where the Z-shaped track 43 is provided below the track 6; The receiving trolley 44 is located on the Z-shaped track 43. The receiving trolley 44 is used to run along the Z-shaped track 43 and to drive the three-dimensional packaging body into the next station; the filling unit 45 is used to fill the three-dimensional packaging body. To hold the contents; the side extrusion and continuous sealing unit 46 is used to extrudate the three-dimensional packaging body from both sides, and the side extrusion and continuous sealing unit 46 is used to seal the remaining transverse sealing areas on the three-dimensional packaging body.

On the basis of the above, embodiments of the present application also provide a processing method for processing the packaging structure 100 using the above processing equipment. The processing method specifically includes:

S1: Preprocess the packaging material through the preprocessing module 1 to make the packaging material into a foldable packaging body;

S2: Form the foldable packaging body into a three-dimensional packaging body through the three-dimensional forming module 2;

S3: Transfer the three-dimensional packaging body from the three-dimensional forming module 2 to the support module 31, and support the three-dimensional packaging body through the support module 31;

S4: Form a preformed inner corner structure on the three-dimensional packaging body through the outer corner module 32 and the support module 31;

S5: Use the extrusion sealing module 33 to squeeze the three-dimensional packaging body to make the preformed inner fold structure become a fixed inner fold structure, and seal and fix the fixed inner fold structure through the extrusion sealing module 33;

S6: Post-process the cornered three-dimensional packaging body through the post-processing module 4 to form the packaging structure 100.

In some embodiments, when the three-dimensional forming module 2 is connected to the support module 31 and the number of packaging bodies is two, the preformed inner corner structure is formed on the three-dimensional packaging body through the outer angled module 32 and the support module 31 The steps include: supporting the three-dimensional packaging body through the fixed support unit 311; controlling the movement of the movable support unit 312 relative to the three-dimensional forming module 2 through the control module 5. The movable support unit 312 cooperates with the outer angled module 32 to form a predetermined shape on the three-dimensional packaging body. Molded inner corner construction.

Specifically, after the support module 31 takes over the three-dimensional packaging body on the three-dimensional forming module 2, the packaging body continues to descend to the fixed support unit 311, and supports the three-dimensional packaging body through the fixed support unit 311. After that, the control module 5 controls the movable support. The unit 312 swings in a direction away from the fixed support unit 311 to tighten the three-dimensional packaging body. Finally, the outer angled module 32 moves toward the support module 31, and the outer angled module 32 is embedded in the three-dimensional packaging body to form a predetermined shape on the three-dimensional packaging body. Molded inner corner construction.

In some embodiments, the step of extruding the three-dimensional packaging body through the extrusion sealing module 33 to make the preformed inner folded corner structure into a shaped inner folded corner structure, and sealing and fixing the fixed inner folded corner structure through the extrusion sealing module 33 includes : The preformed inner folded corner structure is extruded through the side extrusion unit to form the fixed inner folded corner structure; the fixed inner folded corner structure is sealed and fixed by the first sealer 332 .

It should be noted that when processing inward corners on the same side or on opposite sides, the control module of the corner making module must have a reset function. After the corners are made, the corner making module returns to the initial position and the package is released, so that the inner folding corners can move downwards without being affected. Go to the next processing unit; the opposite side processing must be divided into two stations to process the inner folding angles in two different directions, otherwise there will be mutual interference.

In some embodiments, the step of preprocessing the packaging material through the preprocessing module 1 to make the packaging material into a foldable packaging body includes:

The packaging material is pressed with creases by the creasing unit 11;

The cutting and processing unit 13 performs cutting processing on the position where the preformed inner folded corner structure is formed on the packaging material.

In some embodiments, the step of post-processing the cornered three-dimensional packaging body through the post-processing module 4 to form the packaging structure 100 includes: filling the contents into the cornered three-dimensional packaging body through the filling tube 41 ; The main sealing area 103 of the filled three-dimensional packaging body is sealed by the main sealing and cutting device 42, and the three-dimensional packaging body is cut.

In some embodiments, the step of filling the content into the cornered three-dimensional packaging body through the filling tube 41 includes: injecting fluid with particulate matter into the three-dimensional packaging body through the filling tube 41; Inject fluid without particulate matter into the three-dimensional packaging body.

It should be noted that in vertical overflow filling, since the content is liquid food, particles tend to exist near the sealing area of the packaging, causing inconvenience to the sealing process, resulting in incomplete partial sealing and unsatisfactory bag breakage rate. Therefore, a filling sequence is needed to avoid this situation: This embodiment proposes to first fill the fluid with particulate matter into the bottom of the packaging body, and then fill the fluid without particulate matter, so that the upper and lower layers appear. situation to ensure that the probability of particles existing in the main sealing area 103 is reduced, and the product is mechanically shaken after filling.

The packaging structure 100 obtained by the above processing method will be described below with reference to specific embodiments.

The packaging structure 100 provided by the embodiment of the present application includes a packaging body. The packaging body can be used to contain liquid, semi-liquid and semi-granular liquid food, semi-solidified solid or solid particles, such as beverages, liquid food, prepared dishes, condiments, and kitchen seasonings. etc., the packaging body is provided with an inner folding corner 101.

It should be noted that the inner folding corners 101 are divided into two categories. One is those which are arranged longitudinally on the packaging body, such as the longitudinal inner folding line 101 package mentioned in this case; the other is those which are arranged horizontally on the packaging body. , such as the inset angles of the two inward fold lines 104 and the roof-type inward fold angle 101 mentioned in this case. The inset angles that meet specific conditions and the corresponding longitudinal inward fold angles 101 can change spatially with each other. Of course, the packaging structure 100 can also be a flexible package. The packaging body mentioned in this case is not limited to its softness, hardness, size, material, etc. It can also be called a packaging bag or packaging body.

In some embodiments, the packaging body is a packaging body structure container formed by folding flat materials. The packaging body is also provided with an outer folding corner 102 (i.e., an everted folding corner). The outer folding corner 102 is located on the opposite side of the inner folding corner 101; and/or packaging The inner folding corner 101 of the body is provided with a handle for opening the package. Specifically, inner folding corners 101 and outer folding corners 102 are provided on both sides of the top of the packaging body respectively, and two outer folding corners 102 are provided on the bottom of the packaging body. The handle can break the sealing portion 121 on the non-sealing area 106 of the inner folding corner 101 to open the packaging opening, or can also be used to break the sealing area of the inner folding corner 101 and pull out the inner folding corner 101 to form an opening structure.

It should be noted that the beneficial effects brought by setting an inner folding angle 101 include:

First, compared with the roof-type double inner folding corners packaging body in the prior art, when the roof-type double inner folding corners are opened, the two inner folding corners 101 will obstruct each other and cannot be opened in one step. However, the packaging body in this embodiment only An inner folding corner 101 is provided for easy opening, that is, the package is opened along one side of the inner folding corner 101, and the sealing of the inner folding corner 101 can be unsealed and the entire main seal can be opened, which can be opened conveniently.

Secondly, in the unfolded view of the package with a single inner folding corner 101, the top surface is diagonal, that is, the other outer folding corner 102 is opposite. When fully opened, it is an oblique pouring spout, which is very convenient for pouring, such as rice-treasure porridge, etc. For liquid food, you don’t even need a spoon, you can eat it with your head raised. Among the existing packaging technologies, except for cans and flexible packaging, there is no packaging that can open such a large opening, and the oblique ones are ergonomic. If the eight-treasure porridge is packed, single-roof type packaging is used to compare with the existing cans. It is convenient to drink and the transport cost of rectangular packaging is lower than that of cylindrical packaging.

Third, compared to the packaging body with double roof-type inner folds, since the packaging body adopts a single inner fold 101, the top surface of the packaging body is either a triangle or a rectangle, which can be stacked for transportation, thereby greatly improving the efficiency and efficiency of transportation. Convenience.

In some embodiments, the outer folding corner 102 also includes a pouring outlet and a sealing portion 121, wherein the pouring outlet is provided on the outer folding corner, and the pouring outlet is used to pour out the beverage in the packaging body; the sealing portion 121 is provided on the outer folding corner. , the sealing part 121 is used to cover and seal the pouring outlet.

In addition, the sealing portion 121 can also be connected to the outer wall of the packaging body.

It should be noted that the customer can open the package by lifting the outer folding corner 102 to cause the sealing portion 121 connected to the outer wall of the package to break.

Specifically, after the above-mentioned packaging structure 100 is formed, it can be a packaging structure 100 with a triangular or rectangular top surface. The packaging structure 100 has a total of four folding corners, one of which is folded inward to form an inner folding corner 101. Obviously, the inner folding corner 101 is formed. The sealing area 108 of the folded corner 101 has an obvious angle with the main sealing area 103. The optional included angle range can be less than 90° and much greater than 0° according to processing needs; of course, the sealing area 108 of the inner folded corner 101 can also be There is no obvious angle with the main sealing area 103, and the location overlaps. Among them, the upper left corner or the upper right corner of the packaging structure 100 is provided with an inner folding corner 101, and the remaining three corners are provided with an outer folding corner 102. The structure of the outer folding corners 102 can refer to the content of the prior art, and will not be elaborated one by one here.

For example, for a packaging structure 100 with an inner folding corner 101 in the upper left corner and an outer folding corner 102 in the upper right corner, when opening, it can be unsealed from the outer folding corner 102 or from the inner folding corner 101. When unsealing from the inner folding corner 101, only Just gently tear off the seal on the inner corner 101. Of course, you can also further tear off the main seal along the seal on the inner corner 101, thereby completely opening the upper part of the packaging structure 100 to facilitate pouring out the contents of the beverage.

It should be noted that when the preset opening of the package is located in the inner area of the outer folding corner 102 of the package, the preset opening is covered by a film layer that is integrated with the packaging material, and the film layer is directly or indirectly connected to the side wall of the package, the corresponding Compared with the beverage packaging of the prior art, the packaging structure provided by the embodiment of the present application allows customers to rupture the film layer by flipping the folding corners, thereby realizing the function of unsealing the packaging in one step.

As a specific embodiment, the packaging structure 100 is specifically a packaging structure 100 with a triangular top surface having a longitudinal inward folding angle 101. The bottom surface of the packaging structure 100 is a rectangle, and the bottom surface of the packaging structure 100 is located in a horizontal plane. The bottom surface of the packaging structure 100 is used as a reference. , the triangular top surface can be parallel to the bottom surface of the packaging structure 100, that is, the triangular top surface is located in the horizontal plane, and the triangular top surface is a flat triangular top surface; of course, the triangular top surface can also be non-parallel to the bottom surface of the packaging structure 100, that is, triangular The top surface has a preset inclination angle with the horizontal surface, and the triangular top surface is an oblique triangular top surface. The inner folding corner 101 is provided on the first side of the packaging structure 100, and the vertex of the triangular top surface is located on the first side. At the same time, the inner folding corner 101 and the triangular top surface have the same vertex. The bottom edge of the triangular top surface is located on the second side of the packaging structure 100, and the second side of the packaging structure 100 is provided with an outer folding corner 102 connected to the bottom edge. In this embodiment, the inner folded corner 101 includes two overlapping triangular pieces 117, and the size of the triangular pieces 117 is tapered in a direction away from the top surface of the triangle. In other words, the bottom edge of the triangular piece 117 is facing upward and the apex is facing downward. The triangular piece 117 can be a right-angled triangular piece or an obtuse-angled triangle. For this embodiment, the bottom surface of the package will be uneven and slightly convex due to the existence of the longitudinal inward folding angle 101. Preferably, a convex portion is provided at the lower end of the inner folding angle 101 to correct the bottom surface.

It should be noted that the inner folding corner 101 with a top triangle is packaged in an integrated processing technology. The two packaging bodies are a processing unit, which is divided into processing on the same side of the inner folding corner 101 and processing on the opposite side of the inner folding corner 101. The processed The appearance of the products is roughly similar, but the structure is not consistent: for packaging processed on opposite sides, the inner corner 101 area can be sealed with glue. The main seal bears the sealing pressure of the inner corner 101, and the inner corner 101 area only needs to ensure tightness. , and the single folding line of the longitudinal inner folding corner 101 will not overlap with the main seal; however, for packaging processed on the same side, if the inner folding corner 101 is folded into the package and then sealed, the folding line of the inner folding corner 101 will be covered by the main sealing area And seal together, and then when the remaining three outward folding corners are folded, the structure of the inner folding corner 101 will cause certain obstacles to the folding process. The inner folding corner 101 will fold itself to adapt to the folded packaging form. Optimally, The part of the inner folding corner 101 area is a film or a weakened soft layer to facilitate its own folding. In order to facilitate the user to open the package from the side of the inner folding corner 101, a handle is provided on the top of the inner folding corner 101. The handle may be a pull-tab 118 structure. Two pull-tabs 118 are provided on the side walls of the inner corner 101. By lifting the handle, the seal of the inner corner 101 can be opened, thereby opening the package. In addition, the second side of the packaging structure 100 (the side away from the inner folding corner 101) is provided with an outer folding corner 102 that is connected to the bottom edge of the triangular top surface, and the inner side wall of the outer folding corner 102 is provided with an opening. When the package is opened from this side, the outer corners 102 can be lifted, exposing the opening.

In some embodiments, the top surface of the packaging body is triangular, and the packaging body is also provided with a folding angle. The folding angle is located at the base of the top triangle, and the apex of the top triangle is also provided with a handle integrated with the packaging body. 124. The handle 124 is arranged longitudinally on the side wall of the packaging body.

It should be noted that the folding angle located at the base of the top triangle can be an inward folding angle or an outer folding angle 102 . The structure of the so-called integrated handle is actually the longitudinal inward folding angle 101, which is in a reversely folded outward state, and is sealed into one body and then the through hole is processed into the shape of the handle 124.

That is to say, according to the unfolded diagram of the longitudinal inward folding corner in this case, it can be deduced that when the inward folding corner is folded outward, it is a longitudinal everted folding corner, and the so-called integrated handle 124 structure is After the two longitudinally folded triangular pieces 117 are sealed into a composite structure, the through-hole cutting process is performed to take the shape of the handle 124. So when using an integrated processing machine to process the package with the longitudinal integrated handle 124, the two packaging bodies are still used as one processing unit. The processing units are connected end to end, the two packaging bodies are connected, and the two packaging bodies are related to each other. The connecting lines are arranged centrally symmetrically (that is, the diagonal openings are complementary). After overflow filling the lower packaging body, it only needs to be sealed while sealing the diagonal main seal between the two packaging bodies. , seal together with the longitudinal everted corner area (or seal the longitudinal everted corner area first, and then seal the oblique main sealing line between the two packaging bodies), and then cut out the first packaging body and the handle Hand 124 (of course, the cutting operation can also be performed while sealing, and the shape of the handle 124 can be cut while cutting the diagonal main sealing area), and then overfill the second packaging body and seal the remaining main body. Seal and cut out the second package body. Furthermore, two packaging bodies in one processing unit can also be overflow filled, sealed and cut at the same time according to filling speed, yield and other process requirements, greatly improving efficiency.

In some embodiments, the packaging body is provided with a main sealing area 103, and the main sealing area 103 and the inner folding line 104 of the inner folding corner 101 do not intersect. The purpose of this arrangement is to facilitate the opening of the packaging structure 100, that is to say, the packaging body can be opened directly from the inner folding corner 101, making the operation convenient and labor-saving.

It should be noted that the inner folding line 104 mentioned here is the inner folding line 104 in which the inner folding corner 101 area is folded inward. The outer folding line, that is, the angle between any two outer surfaces of the package is greater than 180°, and the folding line between the two outwardly convex surfaces is the outer folding line; vice versa, this case only applies to the inner folding angle of the package. The inner fold line 104 on 101 is defined and discussed.

It should be noted that the packaging body is provided with an inner folding corner 101 formed by being folded inward, and the seal of the inner folding corner 101 is not parallel to the main sealing on the top of the packaging body (the two form an included angle). Compared with the packaging structure 100 in the prior art, due to the difference in the structure after corner insertion, the sealing line of the inward folded corner after inserting the corner needs to be aligned with the transverse main sealing line, so that the folded inward corner is still stressed, so , in addition to ensuring the sealing performance of the inner corner seal, it also requires the sealing strength of the inner corner. In the packaging structure 100 provided in the embodiment of the present application, the seal of the inner folding corner 101 is not parallel to the main seal. Generally speaking, the main seal of the packaging body is located on the top of the packaging body and is arranged in the horizontal direction, and the sealing of the inner folding corner 101 is not parallel to the main seal. Set at a preset angle to the main seal. In this way, since the sealing of the inner folding corner 101 is set at a preset angle with the main seal, the inner folding corner 101 is not structurally stressed, and the sealing pressure on the inner folding corner 101 is borne by the main seal. Therefore, it is only necessary to ensure that the sealing pressure of the inner folding corner 101 is The airtightness of the seal is sufficient, and there is no need to ensure the sealing strength of the inner fold 101. In this way, it can overflow to the next package during filling and then be sealed to ensure that the filling content is sufficient, and it can also simplify the process. Reduce production costs; at the same time, the above setting method allows users to open the package from the inner folding corner 101, thereby providing users with another option in addition to opening the package from the outer folding corner 102, and opening the seal from the inner folding corner 101 can be done without tools. Under the premise of completely unsealing the main seal of the packaging body, it is convenient and labor-saving.

In some embodiments, the inner fold line 104 is a single fold line. Preferably, the inner folding corners 101 are longitudinally arranged inner folding corners 101 .

Specifically, the packaging body is a pillow-shaped packaging body. The inner folding corner 101 is provided at one corner of the pillow-shaped packaging body, and the other three corners of the pillow-shaped packaging body are provided with outer folding corners 102 . In other words, the pillow-shaped packaging body has a total of four folding corners, one of which is folded inward to form the inner folding corner 101, and the other outer folding corners 102 are the same as in the prior art. Of course, after forming such a pillow-shaped packaging body, it can be packed directly without further processing.

In some embodiments, the sealing area 108 of the inner fold 101 is connected to the interior wall of the package. It should be noted that when the package is flat, the sealing area 108 of the inner folded corner 101 may not be sealed from the inside of the package, but may be sealed from the outside of the package. It can be understood that the material of the sealing area 108 of the inner folded corner 101 in the folded state and the materials of the front and rear sides of the packaging body form a four-layer overlapping structure through sealing. Then, first seal the packaging material layer longitudinally, cut an opening for forming the inner fold 101 at a preset position, and insert the inner fold 101 area into the package to form the preformed inner fold 101, and then seal it With the cutting module, the sealing area 108 of the inner folding corner 101 of the package and the main sealing area 103 of the package can be sealed and cut simultaneously, which makes it more convenient to deal with the sealing problem of the inner folding corner 101. Of course, the packaging material can be a single-layer plastic flexible packaging, or a multi-layer composite packaging material. In this way, the customer can also open the package through the inner folding corner 101. For example, in a dairy product bag package with such an inner folding corner 101, a small hole for inserting the straw 122 can be opened through the inner folding corner 101, or the package can be completely opened through the inner folding corner 101. main seal.

In this embodiment, the angle between the seal of the inner folding corner 101 and the main seal is preferably 90°, so that the pillow-shaped packaging body can be further extruded into a packaging structure 100 with a rectangular top surface.

By squeezing the inner folding corners 101 on the packaging body, the longitudinally arranged inner folding corners 101 are transformed into transversely arranged inner folding corners 101, forming a second gusseted structure for the packaging body to transform. It is a packaging body with a rectangular cross section.

Further, the folding line of the inner folding corner 101 is parallel to the main sealing area 103. The inner folding corner 101 is located on the top of the packaging body. The top of the packaging body is also provided with an outer folding corner 102. The outer folding corner 102 is located on the opposite side of the inner folding corner 101; by Squeeze the inner folding corners 101 on the packaging body to transform the longitudinally arranged inner folding corners 101 into transversely arranged inner folding corners 101 to form a second angled structure 114 for the packaging body to transform into a packaging body with a rectangular cross-section. In this way, the packaging body can be fully filled through overflow filling, and the transportation cost can be guaranteed through spatial changes.

Specifically, in order to facilitate the extrusion and folding of the pillow-shaped packaging body into the packaging structure 100 with a rectangular top surface, the corner of the pillow-shaped packaging body provided with the inner folding corner 101 can be extruded and folded to form the second angled structure 114. The two angled structures 114 are provided with a hollow structure, which is used for the pillow-shaped packaging body to form the packaging structure 100 with a rectangular top surface. This can facilitate the pillow-shaped packaging body to be extruded and folded to form the second angled structure 114, and finally form the packaging structure 100 with a rectangular top surface.

At the same time, the hollow structure part is also filled with a first flexible sealing part 107, and the area of the first flexible sealing part 107 is not less than half of the area of the inner corner 101. The first flexible sealing part 107 can be used to cover the hollow. The film structure/film of the structure, the second gusset structure 114 formed after folding, and the film structure disposed on the second gusset structure 114 can be connected to the inner side wall of the side of the packaging structure 100. In this way, When it is necessary to open the packaging structure 100, the top of the packaging structure 100 can be pulled up to tear open the film structure on the second gusset structure 114, thereby forming an outlet for the beverage.

In the next step of processing the pillow-shaped packaging bag, a hollow structure is first provided in the middle area for forming the second gusseted structure 114, then the film structure/film sheet is placed on the hollow structure, and finally the second gusseted structure is formed by extrusion and folding. After inserting the angled structure 114, the second angled structure 114 and the film are sealed with an ultrasonic sealing machine and fixed on the inner side wall of the side of the packaging structure 100, thereby forming the packaging structure 100 with a rectangular top surface.

Further, the sealing area 108 of the inner folding corner 101 of the flat packaging body 105 is provided with a second flexible sealing part 109. The second flexible sealing part 109 may also be a film structure, and the second flexible sealing part 109 is used to seal the inner part. The folding corner 101 is sealed, and when the package is unsealed on the inner folding corner 101 side, a pouring opening can be formed.

In some embodiments, the packaging body can also be provided with two inward folding corners 101, which are located on opposite sides of the bottom of the packaging body, and the top of the packaging body is provided with an opening; and/or the packaging body has a flat cup structure. , by extruding the two inward corners 101 on the flat cup structure 110, two first inserted angle structures 111 are formed, so that the flat cup structure 110 can be transformed into a cup with a rectangular cross-section.
