A device and method for processing combed fiber webs into cotton strips

Abstract

This invention discloses an apparatus and method for processing carded fiber webs into cotton strips, relating to the post-processing of raw cotton materials. The invention comprises a horizontal extrusion roller assembly arranged along the flow direction, a guiding device, a pressure roller-type strip output device, a guide wheel assembly, and a strip drum built into the inner cavity of a strip collector. The fiber web, after being carded and impurity removed by a carding machine, is first extruded by the horizontal extrusion roller assembly and then directed towards the guiding device. After being guided and actively bundled by the guiding device, it forms a uniformly arranged, rectangular fiber web with a cross-section matching the inner cavity of the bundle collector. It then passes through the pressure roller-type strip output device for bundling and extrusion, forming a long strip of cotton strip with uniform width, thickness, and basis weight per unit length. Finally, the long strip of cotton strip is redirected by the guide wheel assembly and conveyed to the strip drum for storage. This invention improves the bonding strength and basis weight uniformity of the cotton strips used in tampons, enhances comfort, and offers strong versatility.

Description

Technical Field

[0001] This invention relates to the field of post-processing technology for raw cotton, degreased cotton, and viscose raw materials, specifically to a device and method for processing carded fiber webs into cotton strips. Background Technology

[0002] A carding machine opens, combs, and removes impurities from cotton or chemical fibers, turning all the curled, lumpy cotton loops into basically straight single fibers. In this process, broken seeds, impurities, and short fibers left over from the previous process are removed, and then the fibers are assembled into cotton slivers of a certain specification and stored in cotton bolls for later use.

[0003] Tampons are made primarily of cotton fibers as the absorbent material, processed using specialized machinery, and are mainly used in feminine hygiene products. In recent years, with the increasing awareness of women's health and environmental protection, the social popularity of tampons has been growing, and annual sales have steadily increased. Domestic manufacturers are increasingly focusing on research into their product processing technology, especially in the processing of cylindrical tampons. The uniformity of the weight per unit length and the bonding strength of the cotton strip used before rolling are key factors affecting user comfort. To effectively improve the comfort of tampons, it is necessary to ensure the bonding strength and uniformity of the weight per unit length of the cotton strip used before rolling. Solving this technical problem requires the design of a specialized device and method for processing the combed fiber web into a cotton strip. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned technical problems by providing a device and method for processing combed fiber webs into cotton strips. Utilizing this device and method effectively improves the bonding strength and uniformity of weight per unit length of the cotton strip used before tampons are rolled, laying the foundation for the comfort of subsequent tampons and thus protecting women's health. Furthermore, this invention allows for flexible adjustment of the distance between the smooth roller and the patterned roller, meeting the production needs of long strips of different thicknesses, and possesses advantages such as wide applicability, strong versatility, and ease of operation.

[0005] The objective of this invention can be achieved through the following measures:

[0006] An apparatus for processing a carded fiber web into a cotton strip according to the present invention includes a horizontal extrusion roller assembly, a guiding device, a pressure roller type strip output device, several sets of guide roller components, and a strip drum built into the inner cavity of the coiler (the fiber web, after being carded and impurity removed by the carding machine, is squeezed by the horizontal extrusion roller assembly and then directed to the guiding device located at the next station; the guiding device can guide and actively gather the flat fiber web to form a uniformly arranged, rectangular fiber web with a cross-section matching the inner cavity of the coiler; the pressure roller type strip output device can gather the rectangular fiber web and extrude it into a long strip of cotton strip with uniform width, thickness, and weight per unit length; the long strip of cotton strip is transported to the inner cavity of the strip drum of the coiler for coiling and storage after being reversed by several sets of guide roller components).

[0007] The horizontal squeeze roller assembly consists of a pair of horizontally arranged squeeze rollers that are parallel to each other at the outlet end of the carding machine and can rotate synchronously in opposite directions. (After being combed and cleaned by the carding machine, the fiber web in a flat state is squeezed by the two squeeze rollers and then turned to be guided to the guide device located at the next station.)

[0008] The guiding device consists of two symmetrically arranged dynamic triangular guide net assemblies, a net support plate, and a guiding transmission mechanism. The two dynamic triangular guide net assemblies can guide and actively gather the fiber net, gradually gathering it into a uniformly arranged, rectangular fiber net with a cross-section matching the inner cavity of the bundler. Simultaneously, during the active gathering process, it can quickly generate new fibers, and even if a fiber break occurs, the guide belt can carry the broken fiber forward, effectively avoiding manual intervention and thus improving production efficiency and product cleanliness. Each dynamic triangular guide net assembly includes one active pulley assembly and two passive pulley assemblies. The guide belt is externally tangentially looped around a driving pulley assembly and two driven pulley assemblies arranged vertically in a right-angled triangle. The guide transmission mechanism is connected to the driving pulley assembly via a belt. (The support plate provides the mounting foundation and support for the driving pulley assembly, driven pulley assemblies, and guide transmission mechanism; the guide transmission mechanism drives the driving pulley assembly to rotate, and then drives the driven pulley assemblies to rotate synchronously through the guide belt, ensuring the cyclic rotation of the guide belt, driving the fiber web in the isosceles obtuse triangle guide area to flow from the large end to the small end, and actively gathering during the guiding process.)

[0009] The pressure roller type tape output device includes a frame, a vertical extrusion roller assembly and a pressure roller transmission mechanism mounted on the frame, and a servo motor driving the pressure roller transmission mechanism (the pressure roller type tape output device can bundle and extrude long strips of cotton tape with uniform width, thickness and weight from a cuboid-shaped fiber web); the vertical extrusion roller assembly includes a cuboid frame (providing a mounting base and mounting cavity for the smooth roller and patterned roller) consisting of four horizontal guide rails and two vertical plates; a patterned roller (with a relatively fixed mounting position) mounted at one end of the inner cavity of the cuboid frame; a smooth roller that can move back and forth along the horizontal guide rails to adjust the roller spacing under the pushing action of a cylinder and the cooperation of a slider (this allows the spacing between the smooth roller and the patterned roller to be adjusted according to the required thickness of the long strip of cotton tape, meeting the production needs of long strips of cotton tape with different thicknesses, and has the advantages of wide applicability, strong versatility and convenient operation); and a bundler and bundler mounting plate (with a cuboid inner cavity) mounted at the gap inlet end opposite the smooth roller and the patterned roller. The bundler in the cavity can bundle the fiber web, preparing it for subsequent rolling and extrusion by the smooth roller and patterned roller into long strips of cotton with uniform width, thickness, and basis weight. The patterned roller has conical bosses arranged in a 45° spiral along its cylindrical surface. (During the rolling and extrusion of the fiber web by the smooth roller and patterned roller, the conical bosses on the roller surface can roll and press patterns onto the surface of the long strip of cotton, effectively improving the bonding strength and aesthetics of the strip.) The inner cavity of the bundler has a rectangular cross-section and a gradually narrowing inverted funnel-shaped structure (facilitating fiber web bundling and effectively ensuring the uniformity of width, thickness, and basis weight per unit length of the long strips of cotton extruded by the smooth roller and patterned roller). The outlet size of the inverted funnel is close to the required specifications of the long strip of cotton and has ample allowance (allowing for processing allowance during the subsequent rolling and extrusion of the fiber web by the smooth roller and patterned roller).

[0010] In this invention, bearings and retaining rings are installed at both ends of the smooth roller and the patterned roller (to ensure that the smooth roller and the patterned roller can rotate smoothly). The bearings and retaining rings are embedded in the slider (the slider also acts as a bearing seat). A guide boss is machined on the inner side of the horizontal guide rail, and a matching locking groove is machined on both sides of the slider (the slider is hung on the horizontal guide rail by the guide boss being embedded in the locking groove). The slider installed at both ends of the smooth roller is connected to the telescopic end of the cylinder (under the thrust of the cylinder, the slider drives the smooth roller to move horizontally back and forth, thereby realizing the adjustment of the distance between the smooth roller and the patterned roller).

[0011] The conical boss described in this invention has a root of 4×4mm, a top of 2×2mm, a height of 2mm from the top to the root, and a center distance of 6mm between two adjacent conical bosses.

[0012] In this invention, the active pulley assembly, the passive pulley assembly, and the guide transmission mechanism are all connected to the support plate by bolts.

[0013] In this invention, the angle between the hypotenuses of the two dynamic triangular guide belts in the guide belt assembly is 120° to 130° (the large angle opening facilitates the flow and active gathering of the fiber web). This area is an isosceles obtuse triangle guide belt area (which facilitates both flow and gathering; at the same time, it can quickly generate new heads during the active gathering process, and even if a web break occurs, the guide belt can carry the broken web forward, which can effectively avoid manual intervention and thus improve production efficiency and product cleanliness).

[0014] In this 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.

[0015] The present invention provides a method for processing a combed fiber web into a cotton strip, which is achieved through the following steps:

[0016] A. Fiber web extrusion and turning: After the loose fibers of raw cotton, degreased cotton, and viscose with a length of 40-50mm are opened, they are combed, impurities removed, and mixed by a carding machine to form a fiber web with a width of 1.1-1.2m and laid flat. The flat fiber web is squeezed up and down by the horizontal extrusion roller assembly and turned before being guided to the guide device located at the next station.

[0017] B. Guiding and Active Bundling: The fiber web is guided and actively bundled in sequence through the guiding device. The flat fiber web is gradually bundled into a uniformly arranged fiber web with a cross-section that matches the inner cavity of the bundler and is arranged in a cuboid shape.

[0018] C. Bundling and extrusion: After being actively bundled in step B, the fiber web, which is arranged in a cuboid shape, continues to move forward and passes through a pressure roller type tape extrusion device for bundling and extrusion. That is, it first passes through a bundler with a cuboid cavity for bundling, and then passes through synchronously and oppositely rotating light rollers and patterned rollers for rolling and extrusion. Finally, it is fastened into a long strip of cotton with a uniform arrangement, a width of 40-50mm, a thickness of 5-8mm, and a weight of 10-15g / m.

[0019] D. Coiling and storage: The long strip of cotton obtained in step C continues to move forward, and after being reversed by several sets of guide pulley components, it is transported to the inner cavity of the belt drum of the coiler for coiling and storage.

[0020] The design principle of this invention is as follows:

[0021] The present invention is designed with a horizontal extrusion roller assembly arranged in sequence along the material flow direction, a guide device, a pressure roller type belt output device, several sets of guide roller components, and a belt drum built into the inner cavity of the belt coiler. After being combed and impurities removed by the carding machine, the flat fiber web is first squeezed by the horizontal extrusion roller assembly and then turned to be guided to the guide device at the next station. The flat fiber web is then guided and actively bundled by the guide device to form a uniformly arranged, rectangular fiber web with a cross-section matching the inner cavity of the bundler. Next, the rectangular fiber web is bundled and squeezed by the pressure roller type belt output device. That is, the fiber web is first bundled by the bundler with a rectangular inner cross-section and a gradually narrowing inverted funnel-shaped structure in the inner cavity. Then, it passes through the gap between the smooth roller and the patterned roller and is rolled and squeezed to produce a long strip of cotton with uniform width, thickness and weight per unit length. Then, the long strip of cotton is reversed by several sets of guide roller components and then conveyed to the inner cavity of the belt drum of the belt coiler for coiling and storage. In other words, more specifically, because the present invention is equipped with independent but coordinated guiding devices and pressure roller-type tape output devices, the fiber web can be guided and actively bundled first, then bundled, and finally pressed and secured by rollers. That is, the cross-section of the cuboid formed by the fiber web after guidance, active bundling, and trumpet-shaped bundling is close to the size and specifications of the long strip cotton tape to be processed and has ample margin. Therefore, after the fiber web is rolled and pressed by the smooth roller and the patterned roller, a long strip cotton tape with uniform width, thickness, and weight per unit length and a certain degree of bonding strength can be formed, laying the foundation for the comfort of using sanitary tampons in subsequent processing, and thus protecting women's health.

[0022] Meanwhile, because the roller surface of the patterned roller is equipped with conical protrusions, patterns can be rolled onto the surface of the long strip of cotton during the rolling and squeezing process of the fiber web by the smooth roller and the patterned roller. On the one hand, this can further improve the bonding strength of the long strip of cotton, and on the other hand, it can also improve the aesthetics and comfort of the long strip of cotton.

[0023] Furthermore, because the smooth roller can move 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 strip cotton belt, so as to meet the production needs of long strip cotton belts of different thicknesses and specifications. It has the advantages of wide applicability, strong versatility and convenient operation.

[0024] The beneficial technical effects of the present invention are as follows:

[0025] The equipment and method of this invention can effectively improve the bonding strength and uniformity of weight per unit length of the tampons used before rolling, laying the foundation for the comfort of using tampons in subsequent processing, thereby protecting women's health. At the same time, this invention also allows for flexible adjustment of the distance between the smooth roller and the patterned roller to meet the production needs of long strips of tampons with different thicknesses, offering advantages such as wide applicability, strong versatility, and ease of operation.

[0033] The horizontal squeeze roller assembly 1 consists of a pair of horizontally arranged squeeze rollers 1-1 arranged in parallel at the outlet end of the carding machine 8 and capable of rotating synchronously in opposite directions. (After being combed and cleaned by the carding machine 8, the fiber web 2, which is laid flat, is squeezed by the two squeeze rollers 1-1 and then turned to be guided to the guide device 3 located at the next station.)

[0034] The guiding device 3 consists of two symmetrically arranged dynamic triangular guide net components 3-1, a net support plate 3-1-1, and a guiding transmission mechanism 3-1-5. (The two dynamic triangular guide net components 3-1 can guide and actively gather the fiber net 2, gradually gathering it into a uniformly arranged, rectangular fiber net 2 with a cross-section matching the inner cavity of the bundler 4-2-9; simultaneously, it can quickly generate new fibers during the active gathering process, and even if a break occurs, the guide belt 3-1-4 can carry the broken fiber forward, effectively avoiding manual intervention and thus improving production efficiency and product cleanliness.) Each dynamic triangular guide net component includes one active pulley assembly 3-1-2, two passive pulley assemblies 3-1-3, and a guide belt 3-1-4. The guide belt 3-1-4... The outer ring is fitted around a driving pulley assembly 3-1-2 and two driven pulley assemblies 3-1-3 arranged vertically in a right-angled triangle. The guide transmission mechanism 3-1-5 is connected to the driving pulley assembly 3-1-2 via a belt. (The support plate 3-1-1 provides the mounting base and support for the driving pulley assembly 3-1-2, the driven pulley assembly 3-1-3 and the guide transmission mechanism 3-1-5; the guide transmission mechanism 3-1-5 drives the driving pulley assembly 3-1-2 to rotate, and then drives the driven pulley assembly 3-1-3 to rotate synchronously through the guide belt 3-1-4, ensuring the cyclic rotation of the guide belt 3-1-4, driving the fiber web 2 in the guide area of ​​the isosceles obtuse triangle to flow from the large end to the small end, and actively gathering during the flow process.)

[0035] The pressure roller type tape output device 4 includes a frame 4-1, a vertical extrusion roller assembly 4-2 mounted on the frame, a pressure roller transmission mechanism 4-3, and a servo motor 4-4 driving the pressure roller transmission mechanism (the pressure roller type tape output device 4 can bundle and extrude long strip-shaped cotton tape 5 with uniform width, thickness, and weight from a cuboid-shaped fiber web 2); the vertical extrusion roller assembly 4-2 includes a cuboid frame composed of four horizontal guide rails 4-2-1 and two vertical plates 4-2-8 (providing an installation base and installation cavity for the smooth roller 4-2-3 and the patterned roller 4-2-4), and a patterned roller 4-2-4 installed at one end of the inner cavity of the cuboid frame. -2-4 (the installation position of the patterned roller 4-2-4 is relatively fixed), under the pushing action of the cylinder 4-2-7 and the cooperation of the slider 4-2-2, the light roller 4-2-3 can move back and forth along the horizontal guide rail 4-2-1 to adjust the roller spacing (this allows the spacing between the light roller 4-2-3 and the patterned roller 4-2-4 to be adjusted according to the required thickness of the long strip cotton strip 5, meeting the production needs of long strip cotton strips 5 with different thicknesses, and has the advantages of wide applicability, strong versatility, and convenient operation). The bundler 4-2-9 and bundler mounting plate 4-2-10 are installed at the gap inlet end opposite to the light roller and the patterned roller (with... The bundler 4-2-9 within the rectangular cavity can bundle the fiber web 2, preparing it for subsequent rolling and extrusion by the smooth roller 4-2-3 and patterned roller 4-2-4 into a long strip of cotton 5 with uniform width, thickness, and weight. The patterned roller 4-2-4 has conical bosses 4-2-4-1 arranged in a 45° spiral along the cylindrical surface of the roller body on its surface. (During the rolling and extrusion of the fiber web 2 by the smooth roller 4-2-3 and patterned roller 4-2-4, the conical bosses 4-2-4-1 on the surface of the patterned roller 4-2-4 can roll and press patterns onto the surface of the long strip of cotton 5, thereby achieving...) This effectively improves the bonding strength of the long strip cotton strip 5, and on the other hand, enhances the aesthetics and comfort of the long strip cotton strip 5; the inner cross-section of the bundler 4-2-9 is rectangular, and the longitudinal direction of the inner cavity is a gradually narrowing inverted funnel structure (which facilitates the bundling of the fiber web 2 and effectively ensures the uniformity of the width, thickness and weight per unit length of the long strip cotton strip 5 rolled and squeezed by the light roller 4-2-3 and the patterned roller 4-2-4). The outlet size of the inverted funnel is close to the required specifications of the long strip cotton strip and has ample margin (to reserve processing margin for the rolling and squeezing of the fiber web 2 by the light roller 4-2-3 and the patterned roller 4-2-4).

The bearings and retaining rings are embedded in the slider 4-2-2 (the slider 4-2-2 also serves as a bearing seat). A guide boss is machined on the inner side of the horizontal guide rail 4-2-1, and a matching locking groove is machined on both sides of the slider 4-2-2 (the slider 4-2-2 is hung on the horizontal guide rail 4-2-1 by the guide boss being embedded in the locking groove). The slider 4-2-2 installed on both shaft ends of the smooth roller 4-2-3 is connected to the telescopic end of the cylinder 4-2-7 (under the thrust of the cylinder 4-2-7, the slider 4-2-2 drives the smooth roller 4-2-3 to move horizontally back and forth, thereby realizing the adjustment of the distance between the smooth roller 4-2-3 and the patterned roller 4-2-4).

[0037] The conical boss 4-2-4-1 described in this invention has a root of 4×4mm, a top of 2×2mm, a height of 2mm from the top to the root, and a center distance of 6mm between two adjacent conical bosses.

[0038] In this invention, the active pulley assembly 3-1-2, the passive pulley assembly 3-1-3, and the guide transmission mechanism 3-1-5 are all connected to the support plate 3-1-1 by bolts.

[0039] In this invention, the included angle of the hypotenuse of the guide belts 3-1-4 in the two dynamic triangular guide belt components 3-1 is 120° to 130° (the large angle opening facilitates the flow and active gathering of the fiber web 2). This area is an isosceles obtuse triangle guide belt area (which facilitates flow and gathering at the same time; at the same time, it can quickly generate a head during the active gathering process, and even if a web break occurs, the guide belt 3-1-4 can carry the broken web forward, which can effectively avoid manual intervention, thereby improving production efficiency and product cleanliness).

Fiber web extrusion and turning: After the loose fibers of raw cotton, degreased cotton and viscose with a length of 40-50mm are opened, they are combed, impurities removed and mixed by the carding machine 8 to form a fiber web 2 with a width of 1.1-1.2m and laid flat. The flat fiber web 2 is squeezed up and down by the horizontal extrusion roller assembly 1 and turned before being guided to the guide device 3 located at the next station.

[0043] B. Guiding and active bundling: The fiber web 2 is guided and actively bundled in sequence by the guiding device 3. The flat fiber web 2 is gradually bundled into a uniformly arranged fiber web 2 with a cross-section that matches the inner cavity of the bundler 4-2-9 and is arranged in a cuboid shape.

[0044] C. Bundling and extrusion: After being actively bundled in step B, the fiber web 2, which is arranged in a cuboid shape, continues to move forward and passes through the pressure roller type tape extrusion device 4 for bundling and extrusion. That is, it first passes through the bundler 4-2-9 with a cuboid inner cavity for bundling, and then passes through the synchronously and oppositely rotating light roller 4-2-3 and patterned roller 4-2-4 for rolling and extrusion. Finally, it is fastened into a long strip cotton tape 5 with a uniform arrangement, a width of 40-50mm, a thickness of 5-8mm, and a weight of 10-15g / m.

[0045] D. Looping and storage: The long strip of cotton 5 obtained in step C continues to move forward, and after being reversed by several sets of guide pulley components 6, it is transported to the inner cavity of the belt drum 7-1 of the belt looper 7 for looping and storage.
