In a specific embodiment, the N-type corner guard buffer air column bag provided by the present invention includes a first outer wall 1, a second outer wall 2, an inner wall 3 and a side wall 4 each having a plurality of air columns. The length of the column is shorter than the length of the air column of the first outer wall 1 and the second outer wall 2, the first outer wall 1 and the inner wall 3 are at a set angle, between the first outer wall 1 and the second outer wall 2 and the outer side wall 4 and between the first outer wall 1 and the inner wall 3. The inner walls 3 are all connected by bending nodes 6, the inner wall 3 and the second outer wall 2 are connected by heat sealing, and the connecting edges of the first outer wall 1, the second outer wall 2 and the inner wall 3 are connected by a three-wall heat sealing line 5 Make connections.

In the above structure, the N-type corner protection buffer air column bag is a new type of shockproof packaging filled with natural air, and is widely used in the transportation packaging of products. The N-type corner guard buffer air column bag includes a first outer wall 1, a second outer wall 2, an inner wall 3 and a side wall 4. Each wall has a plurality of air columns of a certain length, and one air column is separated by two longitudinal sealing lines. The damage and leakage of a single cylinder does not affect the use of other cylinders.

The first outer wall 1 and the second outer wall 2 and the outer side wall 4 and between the first outer wall 1 and the inner wall 3 are all connected by bending at the bending node 6, which refers to a layer of planar shape processed by molds and mechanical equipment. The film includes a flat heat sealing line and 4 rows of bending nodes 6. The size of a single bending node 6 depends on the diameter of the column. Every two bending nodes 6 with a certain distance are a group, which is evenly and centrally distributed in n Each column is in a row, and the first outer wall 1 , the second outer wall 2 , the inner wall 3 and the side wall 4 are formed by bending the bending nodes 6 . The bending node 6 turns one air column into multiple air columns, which can be bent to form a multi-wall structure.

At the same time, the length of the air column of the inner wall 3 is shorter than the length of the air column of the first outer wall 1 and the second outer wall 2. The first outer wall 1 and the inner wall 3 are at a set angle. 1. Inside the second outer wall 2. The inner wall 3 and the second outer wall 2 are connected by heat sealing, and an N-shaped angle is formed between the first outer wall 1 , the inner wall 3 and the second outer wall 2 .

The connecting edges of the first outer wall 1 , the second outer wall 2 and the inner wall 3 are connected by a three-wall heat-sealing line 5 to finally form an N-type protective space. The connecting edges of the first outer wall 1 , the second outer wall 2 and the inner wall 3 are connected by a three-wall heat sealing line 5 , which is convenient for connection and easy to operate.

During packaging, the first outer wall 1, the second inner wall 3 and the side wall 4 are directly attached to the packaging box, and the N-type area formed by the inner wall 3 and the second outer wall 2 is attached to the upper edge area of the TV.

It should be noted that the N-type corner guard buffer air column bag has two different assembly methods according to different transportation environments, as shown in Figure 2 and Figure 3, in Figure 2, the three-wall heat sealing line 5 faces upward, and in Figure 3, the three-wall The heat sealing line 5 is on the side. The second outer wall 2 of the N-type corner protection air column bag is attached to the front of the TV screen, and after the first outer wall 1 and the inner wall 3 are attached to the TV screen, since the TV screen is generally thicker behind the TV screen, the N-type corner protection buffer The air column bag is divided into left and right, and the left and right are a set.

The application of the technical solution provided by the embodiment of the present invention solves the problems of the traditional foam, which are easily damaged, chipped, not environmentally friendly, and high in transportation cost. Compared with traditional foam buffer packaging, it has excellent characteristics of environmental protection and low cost; high strength, air leakage of one cylinder does not affect use, better protection of items, and reduced product damage rate; flat transportation after production When it arrives at the site, it is re-inflated when used, which greatly reduces the transportation cost.

On the basis of the above-mentioned specific embodiment, the first outer wall 1, the second outer wall 2 are perpendicular to the side wall 4, and the shape of the N-type corner guard buffer air column bag is regular. When packing, the first outer wall 1, the second outer wall 2 and the side The wall 4 is attached to the outer packaging box, so that the N-type corner guard buffer air column bag can be fixed in the corrugated box and increase the buffer strength. Of course, the first outer wall 1, the second outer wall 2 and the side wall 4 are perpendicular to only a preferred embodiment, not the only one, the first outer wall 1, the second outer wall 2 may not be perpendicular to the side wall 4, for example, the included angle is greater than 90 degrees.

In another more reliable embodiment, on the basis of any of the above-mentioned embodiments, the end air column of the inner wall 3 is extended with a film of a certain length and width, and the film and the second outer wall 2 are connected through the hammock heat sealing point 11 to form The hammock 10 has a vertical distance between the hammock 10 and the side wall 4 . The N-shaped area formed by the inner wall 3 and the second outer wall 2 is attached to the upper edge and corner area of the TV, and the hammock 10 connects the inner wall 3 and the second outer wall 2, and the number of walls is less under the condition of satisfying the transportation strength, and the effect of cost saving is achieved. The contact between the hammock 10 and the edge of the TV prevents the edge from scratching the air column to cause air leakage, and has a good buffering and shock absorption effect when it falls.

Preferably, there is a certain vertical distance between the hammock 10 and the side wall 4, and the distance is about any value between 20-100 mm, including the end value, to prevent the hammock 10 and the side wall 4 from colliding with each other.

Further optimizing the above technical scheme, the film of the inner wall 3 and the second outer wall 2 are connected through the hammock heat sealing point 11 to form a base layer hammock, and at least one layer of film is added on the surface of the base layer hammock to form a multi-layer hammock. The thickness of the hammock 10 is increased, the strength is increased, and the hammock 10 is more sturdy, and the edges and corners of the TV object are not easy to pierce the hammock 10, and the hammock 10 has better buffering performance and better protection for the TV object.

The thickness of the specific hammock 10 is not limited, that is, the number of additional layers of films on the surface of the base hammock is not limited, and one layer of films can be added to form a double-layer hammock; , At this time, a four-layer hammock is formed, and the specific number of layers can be determined according to the actual application.

There are two ways to form a multi-level hammock:

The first method is that the film of the inner wall 3 is connected to the second outer wall 2 through the hammock heat sealing point 11. After the base hammock is formed, several layers of films are taken on the surface of the base hammock and closely adhered to the base hammock film, which can be the upper part of the base hammock. The surface can also be the lower surface of the base layer hammock; the two ends of several layers of films are heat-sealed and connected to the inner wall 3 and the second outer wall 2 respectively, and the base layer hammock and several layers of films are integrated to form a multi-layer hammock.

It should be noted that the material of the newly added film may be the same as the material of the base hammock, or may be different from the material of the base hammock, all within the protection scope of the present invention.

The second method is to extend the length of the film on the inner wall 3, fold the film inward, and heat-bond the middle of the film with the second outer wall 2 through the hammock heat sealing point 11 to form a base hammock. After that, the film behind the base layer hammock continues to be folded back to the inner wall 3, and is connected with the inner wall 3 through the heat sealing point to form a double-layer hammock with 4 layers of film thickness. Of course, the length of the film is increased, and the film is turned back again to form a multilayer hammock.

For the N-type corner guard buffer air column bag in the above embodiments, the first outer wall 1 and the inner wall 3 are connected by two rows of bending nodes 6 with a set spacing, and the corner air columns are formed at the two rows of bending nodes 6 7. Avoid squeezing the air column of the inner wall 3 and the air column of the outer wall. It should be noted that the distance between the two rows of bending nodes 6 is not limited and depends on the diameter of the column.

On the basis of the above specific embodiments, the three-wall heat-sealing line 5 is heat-sealed at the edges of the first outer wall 1 , the inner wall 3 and the second outer wall 2 to have a set length and form a heat-sealing area 14 .

Specifically, the left edge or the right edge of the first outer wall 1, the inner wall 3 and the second outer wall 2 has an air column that does not enter the air, and the three-wall heat sealing line 5 is heat-sealed in the area of the three-wall edge that does not enter the air column, Referred to as the heat seal zone 14 . The heat-sealing area 14 increases the heat-sealing area and increases the heat-sealing strength.

The heat-sealing area 14 is the heat-sealing position of the three-wall heat-sealing line 5, and the air column reserved for the secondary outer side is designed with no air intake. The size and shape of the trapezoidal confined space are designed according to the product specifications. The trapezoidal closed space is convenient for the processing of the production equipment, so that the heat sealing line can be accurately placed in the heat sealing area 14 without affecting the air column of the first outer wall 1 , the inner wall 3 and the second outer wall 2 .

It should be noted that the three-wall heat-sealing line 5 has a certain length, and the heat-sealing area 14 has a certain area. Under the condition that the product can still be connected to the three-wall when the product is impacted and vibrated, the length of the three-wall heat-sealing line 5 and The size of the heat-sealing zone 14 is not limited.

In another more reliable embodiment, the edges of the first outer wall 1 , the inner wall 3 and the second outer wall 2 have reserved air columns, for example, two reserved air columns 12 on the outermost side and two reserved air columns on the second outer side are provided. The air column, the secondary outer reserved air column is an air column located inside the outermost reserved air column 12 and close to the outermost reserved air column 12 . The outer side of the outermost reserved air column has a beveled edge, and the heat sealing area 14 is located in the second outer reserved air column. The reserved air column can enhance the strength of the contact between the corner of the TV set and the three-wall heat sealing line 5 to avoid transportation during transportation. When the external impact causes the machine corner to tear the heat sealing line directly.

Preferably, the first outer wall 1, the second outer wall 2 and the side wall 4 are provided with a box corner easy-folding area 9 at the reserved air column for changing the diameter of the reserved air column, and the box corner easy-folding area 9 is not for air intake. The shape and size of the box corner easy-folding area 9 are not limited. Generally, there are one or two air columns with small diameters between the box corner easy-folding area 9 and the three-wall heat sealing line 5. The smaller one here is relative. According to the column diameter of each wall air column, the combination of the box corner easy-folding area 9 and its adjacent 1 to 2 small air columns enables the N-type corner guard buffer air column bag to be placed in the carton neatly, enhancing the outer packaging box and the TV. The protection strength between the edges of the machine.

For the N-type corner guard buffer air column bag in the above-mentioned various embodiments, the first outer wall 1 and the inner wall 3 are provided with an air column easy-folding area 8, and the air column easy-folding area 8 does not enter through one or several air columns. The air column easy-folding area 8 is located at the same position of the first outer wall 1 and the inner wall 3, and the size of the air column easy-folding area 8 is smaller than the size of the air column. The specific size and shape of each wall are not limited. It depends on the actual application. The function of the air column easy-folding area 8 is to make the N-type corner guard buffer air column bag more regular and more flexible after inflating, making it easier to fit into the carton without bouncing out to cause the carton to deform, avoiding the product after inflation. The shape is rigid, to prevent the first outer wall 1 and the inner wall 3 from being supported or bombed by the air column to cause the packing box to expand or deform after being equipped, and the buffer strength of the overall packaging is high.

Of course, the arrangement of the air column easy-folding area 8 in the N-type corner guard buffer air column bag is only a preferred embodiment, not the only one. Since the hammock 10 pulls the inner wall 3 and the second outer wall 2 to form a certain angle, it will not squeeze Press the first outer wall 1, so the angle between the outer wall and the side wall 4 can still be 90 degrees, so the shape of the product is relatively regular in most cases, rarely rebounding and expanding the box, and there is no need to set the air column easy-folding area 8 .

Under the condition that other components are not changed, the side wall 4 is provided with a box body buckle area 17, that is, the continuous 3-4 air columns on the side wall 4 are designed without air intake, and the box body is formed on the side wall 4. The handle area 17 avoids the handle of the packing box, which is convenient for the N-type corner guard and buffer air column bag to be taken and placed from the packing box. If the outer packing box does not have a handle, the N-type corner guard cushion air column bag does not have this area. The shape, total length and overall width of the box handle area 17 are determined according to the location and size of the box handle area.

On the basis of any of the above-mentioned embodiments, the first outer wall 1 and the inner wall 3 are connected by the positioning line 16, and after the two are connected, the first outer wall 1, the inner wall 3 and the second outer wall 2 pass through the three-wall heat sealing line 5 to connect, the connection is more convenient and easy to operate, the positioning line 16 can make the protection area larger, the buffer effect better, and the aesthetics higher.

In the N-type corner protection buffer air column bag provided by the present invention, under the condition that other components are not changed, the flat heat sealing line heat seals the film, and the air column is separated by the flat heat sealing line to form n air columns, each air column is formed. The diameters of the columns can be the same or different. The length of the air column, the diameter of the air column, the shape of the air column and the number of the air column are not limited, and can be determined according to the specifications of the TV and other items, and are all within the protection scope of the present invention.

The air column is separated by a flat heat sealing line. The flat heat sealing line includes horizontal sealing line, vertical sealing line and heat sealing pattern, among which the heat sealing pattern includes dragon line, figure eight, smiley face and so on. There are many combinations of the plane heat sealing line, as long as n air columns can be formed, and Fig. 7 and Fig. 8 are only two of them. The plane heat sealing line in FIG. 7 includes a first horizontal sealing line A1, a second horizontal sealing line A2, and a fourth horizontal sealing line A4. The three horizontal sealing lines form the main air channel, which is mainly used for air gun or automatic inflator inflation. The n horizontal sealing lines A3, the n vertical sealing lines C and the dragon-shaped lines E form the cylinder air inlet 15 and the cylinder air passage, mainly to form an air storage chamber and facilitate air intake. The plane heat sealing line in Fig. 8 includes the main air channel formed by the transverse sealing line B1 and the transverse sealing line B2, the n longitudinal sealing lines D and the dragon-shaped line F form the cylinder, and the high temperature resistant coating 16 is also used to form the gas valve for easy intake.

In order to achieve the purpose of protecting objects of different shapes, some designs are added on the basis of the flat heat sealing line to better fit and protect the objects. For example, in the design of joints, one air column can be changed into multiple air columns, which are bent to form each wall; another example is to design some heat sealing line segments and longitudinal sealing lines to form a closed space, and the closed space does not enter the air, so as to meet some special functions , such as the easy-to-break area 8 of the air column, the heat-sealed area 14 and the easy-to-break area 9 of the box corner in the N-type corner guard buffer air column bag.

It should be noted that the forming method of the closed space without air intake is as follows: 1 air column is separated by 2 longitudinal sealing lines, and the shaded part of the non-air intake area as shown in the figure is an additional air column in one air column. The heat sealing line parallel to the longitudinal sealing line of the air column is overlapped with one of the longitudinal sealing lines of the air column through two oblique short lines to form a trapezoidal or rectangular closed space. There are also N straight short lines in the closed space to strengthen the heat sealing. The overlapping of lines and longitudinal sealing lines. Preferably, each line intersects with small rounded corners.

Specifically, the manufacturing method of the N-type corner guard buffer air column bag is as follows:

The first step is to process a flat film through molds and mechanical equipment, including flat heat sealing lines, 4 rows of bending nodes 6 and some air-tight areas, as shown in the black filled part. The size of a single bending node 6 depends on the diameter of the column, and every two bending nodes 6 with a certain interval are a group, which are evenly and centrally distributed in a row within the n column diameters. The first row and the second row form the corner air column 7 , and the third row and the fourth row form the side wall 4 . The air-closed area includes the easy-folding area 8 of the air column, the heat-sealing area 14 and the easy-folding area 9 of the box corner. The size, shape and position of the air column easy-folding area 8 are designed according to the product specifications; the heat-sealing area 14 is the heat-sealing position of the three-wall heat-sealing line 5, and the size and shape are designed according to the product specifications; the box corner easy-folding area 9 and the heat-sealing area 14 There are generally 1 to 2 air columns with smaller diameters in between, such as air column 1 in Figure 4; the size and shape of the box corner easy-to-fold area 9 are designed according to product specifications.

The second step is to fold three times and heat seal twice by the folding machine, and fold inward along the first folding line 131 in FIG. 4 to form a two-layer film, as shown in FIG. Fold outward and fold inward along the third folding line 133 to form a three-layer film, as shown in Figure 6. In the first heat sealing, the hammock 10 is heat sealed to connect with the second outer wall 2; the second heat sealing is for the three-wall heat sealing line 5, and the effect is shown in Figure 6.

The third step is to inflate through the inflation port 15 .

It should be noted that the position of the inflatable port 15 is not limited, and it can be arranged at the head or tail of the air column, or in the middle of the air column. When the number increases, the inflation speed is accelerated; you can also choose a setting to simplify the structure. The specific number and method are not limited, and can be determined according to the actual application.

When the inflation port 15 is arranged at the head or tail of the air column, that is, the inflation port 15 is arranged at the position of the second outer wall 2 and the second inner wall 4 at the position of the head and tail heat sealing line 14, the inflation port 15 is located at the N-type corner guard buffer air column On the side of the bag, it is not only easy to process and easy to set, but also easy to operate, convenient and quick to inflate.
