Background technique

The carding machine is used to open, comb and remove impurities from cotton fibers or chemical fibers, so that all curled cotton loops become basically straight single fibers. In the process, broken seeds, impurities and short fibers left over from the previous process are removed, and then cotton strips of a certain specification are integrated and stored in cotton tubes for future use.

Tampons are made of cotton fibers as the main absorbent material, which are processed and formed by special machinery and are mainly used in female hygiene products. In recent years, with the continuous improvement of women's health awareness and environmental awareness, the social popularity of tampons has become higher and higher, and the annual sales volume of products has grown steadily. Domestic related production enterprises are paying more and more attention to the research of their own product processing technology, especially in the processing of cylindrical tampons. The uniformity of the weight per unit length and the consolidation strength of the cotton tape used before rolling are one of the key factors affecting the comfort of users. In order to effectively improve the comfort of tampons, it is necessary to ensure the consolidation strength of the cotton tape used before rolling and the uniformity of the weight per unit length. In order to solve this technical problem, it is necessary to specially design a device and method for processing the combed fiber web into a cotton tape.

The guide device is composed of two symmetrically arranged dynamic triangular guide net components, a net supporting plate, and a guide transmission mechanism (the two dynamic triangular guide net components can guide and actively converge the fiber net, gradually converging it into a uniformly arranged fiber net with a cross section matching the inner cavity of the bundler and arranged in a rectangular shape; at the same time, it can also quickly grow a head during the active convergence process, and even if a net break occurs, the guide net belt can carry the broken net forward, which can effectively avoid manual intervention, thereby improving production efficiency and product cleanliness). Each dynamic triangular guide net component includes an active pulley component, two passive pulley components, The guide belt is externally looped on a driving pulley assembly and two passive pulley assemblies arranged vertically in a right-angled triangle. The guide transmission mechanism is connected to the driving pulley assembly through a belt (the support plate provides an installation foundation and support for the driving pulley assembly, the passive pulley assembly and the guide transmission mechanism; the guide transmission mechanism drives the driving pulley assembly to rotate, and then drives the passive pulley assembly to rotate synchronously through the guide belt to ensure the circular rotation of the guide belt, driving the fiber web in the guide area of the isosceles obtuse triangle to flow from the large end to the small end, and actively converges during the diversion process);

The pressure roller type tape output device includes a frame, a vertical squeezing roller assembly and a pressure roller transmission mechanism installed on the frame, and a servo motor driving the pressure roller transmission mechanism (the pressure roller type tape output device can bundle the fiber web arranged in a rectangular shape and extrude a long cotton strip with uniform width, thickness and gram weight); the vertical squeezing roller assembly includes a rectangular frame composed of four horizontal guide rails and two vertical plates (providing an installation foundation and an installation cavity for the smooth roller and the pattern roller), a pattern roller installed at one end of the inner cavity of the rectangular frame (the installation position of the pattern roller is relatively fixed), a smooth roller that can translate back and forth along the horizontal guide rail to adjust the roller spacing under the driving action of the cylinder and the cooperation of the slider (thereby adjusting the spacing between the smooth roller and the pattern roller according to the required thickness of the long cotton strip to meet the production requirements of long cotton strips of different thickness specifications, and has the advantages of wide application range, strong versatility and easy operation), a buncher and a buncher mounting plate (having a rectangular body) installed at the entrance end of the gap opposite to the smooth roller and the pattern roller The bundler of the cavity can bundle the fiber web, so as to prepare for the subsequent rolling and extrusion of the fiber web by the smooth roller and the pattern roller into a long cotton strip with uniform width, thickness and gram weight); the roller surface of the pattern roller is provided with conical bosses arranged in a 45° spiral line along the cylindrical surface of the roller body (in the process of rolling and extruding the fiber web by the smooth roller and the pattern roller, the conical bosses on the roller surface of the pattern roller can roll out a pattern on the surface of the long cotton strip, which can effectively improve the consolidation strength of the long cotton strip on the one hand, and improve the beauty and comfort of the long cotton strip on the other hand); the cross-section of the inner cavity of the bundler is rectangular, and the longitudinal direction of the inner cavity is a gradually shrinking inverted trumpet structure (which is convenient for bundling the fiber web and effectively ensures the uniformity of the width, thickness and gram weight per unit length of the long cotton strip extruded by the smooth roller and the pattern roller later), and the outlet size of the inverted trumpet is close to the required specification of the processed long cotton strip and has a lot of margin (reserving processing margin for the subsequent rolling and extrusion of the fiber web by the smooth roller and the pattern roller).

In the present invention, both axial ends of the smooth roller and the pattern roller are installed with bearings and retaining rings (to ensure that the smooth roller and the pattern roller can rotate smoothly), and the bearings and retaining rings are embedded in the slider (the slider also serves as a bearing seat); a guide boss is processed on the inner side surface of the horizontal guide rail, and a card-embedded groove matching the guide boss is processed on both sides of the slider (the guide boss is hung in the card-embedded groove, and the slider is hung on the horizontal guide rail); the sliders installed at the two axial ends of the smooth roller are connected to the telescopic end of the cylinder (under the thrust of the cylinder, the smooth roller is driven to move horizontally back and forth through the slider, thereby realizing the adjustment of the distance between the smooth roller and the pattern roller).

The root of the conical boss described in the present invention is 4×4 mm, the top is 2×2 mm, the height from the top to the root is 2 mm, and the center distance between two adjacent conical bosses is 6 mm.

The included angle of the hypotenuse section of the guide belt in the two dynamic triangular guide net assemblies in the present invention is 120°~130° (the large-angle opening is convenient for the flow guidance and active convergence of the fiber net), and this area is an isosceles obtuse triangle guide area (convenient for guiding and converging at the same time; at the same time, it can also quickly grow a head during the active convergence process, and even when the net is broken, the guide belt can carry the broken net forward, which can effectively avoid human intervention and thereby improve production efficiency and product cleanliness).

In the present invention, the vertical plate and the horizontal guide rail, the clusterer and the clusterer mounting plate, and the clusterer mounting plate and the horizontal guide rail are all connected by bolts.

A method of processing a carded fiber web into a cotton tape according to the present invention is achieved by the following steps:

A. Fiber web extrusion and steering: The loose fibers of raw cotton, absorbent cotton and viscose with a length of 40-50 mm are opened, combed, removed and mixed by a carding machine to form a fiber web with a width of 1.1-1.2 m. The flat fiber web is squeezed up and down by a horizontal squeezing roller assembly and turned to be guided to the guide device at the next station;

B. Flow guidance and active convergence: The fiber web is guided and actively converged in sequence by the guiding device, and the flat fiber web is gradually converged into a fiber web with uniform arrangement, a cross section matching the inner cavity of the converger, and a rectangular arrangement;

C. Bundling and extruding the tape: The fiber web arranged in a rectangular shape after active bundling in step B continues to move forward and passes through a pressure roller type tape outlet device for bundling and extruding the tape. That is, it first passes through a bundling device with a rectangular inner cavity for bundling, and then passes through a synchronously counter-rotating smooth roller and a patterned roller for rolling and extrusion, and finally is fastened into a long cotton tape with a uniform arrangement, a width of 40-50 mm, a thickness of 5-8 mm, and a gram weight of 10-15 g/m;

D. Coil and store: The long cotton tape obtained in step C continues to move forward, and after being reversed by several groups of guide pulley components, it is transported to the inner cavity of the belt barrel of the belt coiler and coiled and stored.

The design principle of the present invention is as follows:

The present invention is designed with a horizontal squeezing roller assembly, a guide device, a pressure roller type belt discharging device, several groups of guide wheel components, and a belt barrel built into the inner cavity of the belt looper, which are arranged in sequence along the flow direction of the logistics. In this way, the fiber web in a flat state after being combed and removed by the carding machine is first squeezed by the horizontal squeezing roller assembly and then turned to be guided to the guide device located at the next station; the fiber web in a flat state is then guided and actively bundled by the guide device to form a uniformly arranged fiber web with a cross section matching the inner cavity of the bundler and arranged in a rectangular parallelepiped; then, the fiber web arranged in a rectangular parallelepiped is bundled and squeezed by the pressure roller type belt discharging device, that is, the fiber web is first bundled by the bundler with a rectangular inner cavity cross section and a gradually shrinking inverted trumpet structure in the longitudinal direction of the inner cavity, and then penetrates through the gap between the smooth roller and the pattern roller and is rolled and squeezed to extrude a long strip of cotton with uniform width, thickness and unit length weight; then, the long strip of cotton is transferred to the inner cavity of the belt barrel of the belt looper for coiling and storage after being changed by several groups of guide wheel components. In other words, more specifically, since the present invention is provided with a guide device and a pressure roller type tape output device that are independent of each other and coordinated front and back, the fiber web can be first guided and actively bundled, then bundled, and finally squeezed and tightened by rollers. That is, the cross-section of the rectangular parallelepiped formed by the fiber web after guidance, active bundling, and trumpet-mouth bundling is close to the size specification of the required long cotton strip and has a lot of margin. Therefore, after the fiber web is rolled and squeezed by the smooth roller and the patterned roller, a long cotton strip with uniform width, thickness and gram weight per unit length and a certain consolidation strength can be formed, which lays the foundation for the comfort of subsequent processing of tampons, thereby protecting women's health.

At the same time, since a conical boss is arranged on the roller surface of the pattern roller, a pattern can be rolled out on the surface of the long cotton strip during the rolling and extrusion of the fiber web by the smooth roller and the pattern roller. On the one hand, it can further enhance the consolidation strength of the long cotton strip, and on the other hand, it also enhances the appearance and comfort of the long cotton strip.

In addition, because the smooth roller can be translated back and forth along the horizontal guide rail to adjust the roller spacing under the pushing action of the cylinder and the cooperation of the slider, the spacing between the smooth roller and the patterned roller can be adjusted according to the required thickness of the long cotton strip, thereby meeting the production needs of long cotton strips of different thickness specifications. It has the advantages of wide application range, strong versatility and easy operation.

The beneficial technical effects of the present invention are as follows:

The device and method of the present invention can effectively improve the consolidation strength of the cotton tape used before the tampon is rolled and the uniformity of the weight per unit length, laying a foundation for the comfort of the subsequent processing of the tampon, thereby protecting women's health. At the same time, the present invention can also flexibly adjust the spacing between the smooth roller and the patterned roller to meet the production needs of long cotton tapes of different thickness specifications, and has the advantages of wide application range, strong versatility, and easy operation.

That is, it first passes through a bundling device (4-2-9) with a rectangular inner cavity for bundling, and then passes through a synchronously counter-rotating smooth roller (4-2-3) and a patterned roller (4-2-4) for rolling and extrusion, and finally is fastened into a uniformly arranged long cotton tape (5) with a width of 40 to 50 mm, a thickness of 5 to 8 mm, and a gram weight of 10 to 15 g/m; D. Coil and store: The long cotton tape (5) obtained in step C continues to move forward, passes through a plurality of sets of guide wheel components (6) for reversal, and is then transported to the inner cavity of the tape barrel (7-1) of the coiling device (7) for coiling and storage.
