Description

Technical Field

[0001] This application relates to the field of carding machine technology, and in particular to a sliver forming device for a carding machine used in the production of recycled cotton. Background Technology

[0002] The working principle of a carding machine is to open, comb, and remove impurities from the cotton (fiber) rolls sent from the previous process or the oily cotton (chemical fiber) layer supplied by the cotton box, so that all the curled and blocky cotton loops become basically straight single fibers. In this process, broken seeds, impurities, and short fibers left over from the cleaning process are removed. Then, the cotton is integrated into cotton slivers of a certain specification and stored in cotton canisters for use in the drawing process.

[0003] In related technologies, during operation, short fibers and impurities easily adhere to the surface of the pressure rollers of a carding machine's sliver forming device. Over time, this can reduce the quality of the sliver, as the short fibers and other impurities negatively impact the sliver's quality. During cleaning, although cotton fibers are relatively light, they can easily clog the air outlet of the cotton fiber collection device, weakening the airflow or preventing further collection. Timely cleaning is necessary, but this requires stopping the machine, which is time-consuming and labor-intensive. Summary of the Invention

[0004] To facilitate the collection of cotton fibers, this application provides a sliver forming device for a carding machine used in the production of recycled cotton.

[0005] A carding machine for recycled cotton production includes a sliver forming device, a worktable, and a cleaning component and a recycling component are provided on the worktable; The cleanup components include: The first rotating cylinder is rotatably connected to the worktable; Several blades are detachably connected to the first rotating cylinder, and a blade is provided on the side of the blades away from the inner wall of the first rotating cylinder; Several sheets are arranged in a circle, and several blades cooperate to form a thread inlet. After the first rotating cylinder rotates, an airflow is formed at the sheets in the same direction as the cotton thread. The recyclable components include: The second rotating cylinder is rotatably connected to the worktable, and the second rotating cylinder is connected to the first rotating cylinder; A drive motor is connected to the worktable, and the drive motor's power shaft is connected to the second rotating drum via a belt to drive the second rotating drum to rotate. The first recycling cylinder is fixedly connected to the workbench, and the first recycling box is rotatably connected to the second rotating cylinder. The cotton pressing component is located on the first recycling cylinder, and two cotton pressing components cooperate to form a cotton pressing hole.

[0006] By adopting the above technical solution, the cleaning component can collect the cotton lint scattered during the forming of recycled cotton. Its rotating blades form an airflow in the same direction as the cotton thread movement, which can adsorb and blow away the cotton lint. The blades can cut off the long cotton lint that is not compacted or sticks up on the cotton thread. The recycling component can store the cotton lint in a concentrated manner, reducing the loss of recycled cotton during forming. The drive motor drives the second rotating drum to rotate, thereby making the entire recycling component work. The cotton pressing component can further process the cotton thread, which is convenient for subsequent operations.

[0007] Optionally, two fixed rods are provided on the worktable, and a yarn bundle wheel is rotatably connected to the fixed rod. The distance between the two yarn bundle wheels is less than the diameter of the inlet hole, and the cotton thread output by the carding machine is located between the two yarn bundle wheels.

[0008] By adopting the above technical solution, two fixed rods with yarn-binding wheels are set on the worktable, and the distance between the two yarn-binding wheels is smaller than the diameter of the inlet hole, so that the cotton yarn output by the carding machine is between the two yarn-binding wheels. This changes the movement direction of the cotton yarn on both sides, and initially gathers the cotton yarn. At the same time, a cleaning component and a recycling component are set on the worktable. The cleaning component uses the first rotating drum and blades to create airflow and collects scattered cotton lint with the help of blades.

[0014] By adopting the above technical solution, a negative pressure fan draws cotton fibers from the first collection cylinder into the second collection cylinder through a pipe. A filter screen intercepts the cotton fibers, and liquid assists in capturing them. A circulating pump delivers the liquid to spray heads, which spray water to wet the cotton fibers entering the second collection cylinder, preventing them from flying out of the exhaust vent and achieving effective cotton fiber recovery, thus reducing losses during the sizing of recycled cotton. Furthermore, the two cotton collection ports rotate and, under the action of the negative pressure fan, create a spiral airflow within the second rotating cylinder, thereby improving the cotton fiber collection efficiency.

[0028] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 This application will be described in further detail below.

[0029] A sliver forming device for a carding machine used in recycled cotton production, referring to Figure 1 The system includes a workbench 1, on which a cleaning component and a recycling component are installed. The cleaning component is used to collect cotton lint that is scattered during the forming of recycled cotton, and the recycling component is used to store the cotton lint in a centralized manner. The cleaning component and the recycling component reduce the loss of recycled cotton during the forming of recycled cotton.

[0030] Two fixed rods 2 are fixedly connected to the worktable 1. Each fixed rod 2 is rotatably connected to a yarn-binding wheel 3, and the two opposing planes of the yarn-binding wheel 3 are parallel to the upper end face of the worktable 1. The upper surface of the yarn-binding wheel 3 is provided with a yarn-binding groove. The yarn-binding grooves of the two yarn-binding wheels 3 cooperate to form a yarn-binding hole. The cotton thread pulled out from the cotton outlet of the carding machine passes through the yarn-binding hole. The cotton thread located on both sides of the yarn-binding wheel 3 abuts against the inner wall of the yarn-binding groove of the yarn-binding wheel 3, thereby changing the movement direction of the cotton thread on both sides, thus initially gathering the cotton thread.

[0031] Reference Figure 1 , Figure 2The cleaning assembly includes two first bearing rings 4 mounted on the worktable 1, with the first bearing rings 4 coaxially arranged with the wire harness hole. The outer ring of the first bearing ring 4 is fixedly connected to the worktable 1, and the inner ring of the first bearing ring 4 rotates relative to the outer ring. Both inner rings of the two first bearing rings 4 are fixedly connected to the same first rotating cylinder 5, allowing the first rotating cylinder 5 to rotate on the worktable 1. The first rotating cylinder 5 is hollow, and its axis coincides with the wire harness hole.

[0032] The inner wall of the first rotating cylinder 5 has several mounting grooves 6 arranged circumferentially along its inner wall. Each mounting groove 6 has a screw hole at its bottom. A blade 8 is inserted into each mounting groove 6, with a fixing hole at one end. The axis of the fixing hole coincides with the axis of the screw hole. A screw 7 passes through the fixing hole and extends into it, connecting to the inner wall of the screw hole via threads, thus fixing the blade 8 inside the first rotating cylinder 5. When the first rotating cylinder 5 rotates, the blades 8 generate airflow, and the airflow direction is the same as the direction of cotton thread movement. This attracts the cotton fibers scattered when the cotton thread passes through the yarn guide wheel 3 and blows them in the direction of the cotton thread's movement.

[0033] Several leaf blades 8, located away from the first rotating cylinder 5, form a thread inlet hole. The axis of the thread inlet hole coincides with the axis of the thread bundling hole, and the diameter of the thread bundling hole is smaller than the diameter of the thread inlet hole, thus preventing the cotton thread from tangling on the leaf blades 8. Additionally, a blade 9 is integrally formed at the end of the leaf blade 8 away from the first rotating cylinder 5, with gaps between adjacent blades 9 to cut off any uncompressed or protruding long cotton fibers from the thread. Simultaneously, the airflow generated by the rotation of the leaf blades 8 blows away the cut cotton fibers.

[0034] Reference Figure 1 , Figure 2 , Figure 3 The recycling assembly includes two second bearing rings 10 mounted on the workbench 1, with the second bearing rings 10 coaxially arranged with the first rotating cylinder 5. The outer ring of each second bearing ring 10 is fixedly connected to the workbench 1, and the inner ring of each second bearing ring 10 rotates relative to the outer ring. Both inner rings of the two second bearing rings 10 are fixedly connected to the same second rotating cylinder 11, allowing the first rotating cylinder 5 to rotate on the workbench 1. The second rotating cylinder 11 is hollow, with the first rotating cylinder 5 extending into it, and a gap is provided between the first rotating cylinder 5 and the second rotating cylinder 11.

[0035] Reference Figure 1 , Figure 4The surface of the first rotating cylinder 5 is provided with an annular first driving groove 12. A plurality of first permanent magnets 13 are sealed and fixed within the first driving groove 12 by epoxy resin. The first permanent magnets 13 are arranged along the bottom of the first driving groove 12, so that the first permanent magnets 13 surround the surface of the first rotating cylinder 5. Furthermore, between two adjacent first permanent magnets 13, the magnetism on the side furthest from the bottom of the first driving groove 12 is opposite. Simultaneously, the inner wall of the second rotating cylinder 11 is provided with an annular second driving groove 14, and the center of the second driving groove 14 is located on the same plane as the center of the first driving groove 12. A plurality of second permanent magnets 15 are sealed and fixed within the second driving groove 14 by epoxy resin. The second permanent magnets 15 are arranged along the bottom of the first driving groove 12, so that the second permanent magnets 15 surround the interior of the second rotating cylinder 11. Furthermore, between two adjacent second permanent magnets 15, the magnetism on the side furthest from the bottom of the second driving groove 14 is opposite. In addition, a drive motor 16 is fixedly connected to the workbench 1. The power shaft of the drive motor 16 is connected to the surface of the second rotating cylinder 11 via a belt to drive the second rotating cylinder 11 to rotate. When the second rotating cylinder 11 rotates, the second permanent magnet 15 and the first permanent magnet 13 drive the first rotating cylinder 5 to rotate through attraction and repulsion.

[0036] A first recycling cylinder 17 is fixedly connected to the workbench 1. The first recycling cylinder 17 includes a base 1701, which is fixedly connected to the workbench 1. The base 1701 has a cotton outlet hole for threading cotton, and the cotton outlet hole is coaxially arranged with the second rotating cylinder 11, so that the cotton thread can smoothly extend from the cotton outlet hole. An inner baffle 1702 is fixedly connected to the base 1701 near the cotton outlet hole. The inner baffle 1702 smoothly transitions with the inner wall of the cotton outlet hole. At the same time, the inner baffle 1702 is inserted into the second rotating cylinder 11. In addition, an outer baffle 1703 is fixedly connected to the base 1701 on the same side as the inner baffle 1702, and a third bearing ring 18 is provided on the outer wall of the outer baffle 1703. The inner ring of the third bearing ring 18 is fixedly connected to the outer surface of the outer perimeter 1703, and the outer ring of the third bearing ring 18 is fixedly connected to the inner wall of the second rotating cylinder 11, thereby reducing the impact of the second rotating cylinder 11 on the outer perimeter 1703, the inner perimeter 1702, and the chassis 1701 after it rotates.

[0037] Reference Figure 3 , Figure 4Two arc-shaped plates 19 are slidably connected between the outer perimeter 1703 and the inner perimeter 1702. Two arc-shaped sliding grooves are formed on the arc-shaped plates 19, and the outer perimeter 1703 and the inner perimeter 1702 extend into their respective sliding grooves. Simultaneously, the two arc-shaped plates 19 cooperate to form two cotton inlets 20, through which cotton fibers can pass into the first recycling cylinder 17. A fixing ring 21 is fixedly connected to the side of the arc-shaped plate 19 closest to the first rotating cylinder 5, and a rubber pad 22 is fixedly connected to the inner wall of the fixing ring 21. Meanwhile, two telescopic motors 23 are fixedly connected to the second rotating cylinder 11. A drive rod 24 is fixedly connected to the power shaft of the telescopic motor 23. The drive rod 24 is sequentially fitted with the corresponding rubber pad 22 and a vibration damping spring 25. The vibration damping spring 25 and the rubber pad 22 are used to reduce the vibration experienced by the drive rod 24 when it rotates with the second rotating cylinder 11. After the second rotating cylinder 11 rotates, the arc-shaped plates 19 can rotate synchronously under the action of the drive rod 24.

[0038] A ceramic-made cotton-pressing block 26 is fixedly connected to the end of the drive rod 24 away from the telescopic motor 23. The cotton-pressing block 26 has a cotton-pressing groove 27. The cotton-pressing grooves 27 on two cotton-pressing blocks 26 mate to form a cotton-pressing hole. The cotton thread passes through the cotton-pressing hole and then through the exit hole. When the drive shaft of the telescopic motor 23 is fully extended, the diameter of the cotton-pressing hole is smaller than the diameter of the thread-binding hole, and the diameter of the exit hole is smaller than the diameter of the thread-binding hole but larger than the diameter of the cotton-pressing hole, thereby reducing friction when the cotton thread extends. Additionally, one cotton-pressing block 26 has an integrally formed connecting rod 28, and the other cotton-pressing block 26 has a connecting groove 29. When installed in place, the connecting rod 28 extends into the connecting groove 29, thereby improving the stability between the two cotton-pressing blocks 26. Furthermore, the two ends of the damping spring 25 abut against the cotton-pressing block 26 and the fixing ring 21 respectively, further improving the stability of the cotton-pressing block 26.

[0039] Reference Figure 1 , Figure 5 , Figure 6The first recycling cylinder 17 is connected to a negative pressure fan 30 via a pipe. The outlet of the negative pressure fan 30 is connected to a second recycling cylinder 31 via a pipe and is fixedly connected to the top surface of the second recycling cylinder 31. An exhaust port 32 is provided at the top of the second recycling cylinder 31. Both the first recycling cylinder 17 and the second recycling cylinder 31 are made of metal. A wire 33 is provided on the surface of the first recycling cylinder 17 and is fixedly connected to its bottom surface. A filter screen 34 is fixedly connected to the inner wall of the second recycling cylinder 31. Clean water is injected into the second recycling cylinder 31, and the water level is lower than that of the filter screen 34. The second recycling cylinder 31 is connected to a circulation pump 35 via a pipe on its side wall. A spray head 36 is fixedly connected to the inner wall of the second recycling cylinder 31 above the filter screen 34. The outlet of the circulation pump 35 is connected to the inlet of the spray head 36 via a pipe, so that clean water can be sprayed out from the spray head 36 under the action of the circulation pump 35, thereby wetting the cotton wool entering the second recycling cylinder 31 and preventing it from flying out from the exhaust port 32.

[0040] The implementation principle of this application embodiment is as follows: When the drive motor 16 drives the second rotating cylinder 11 to rotate via the belt, the first rotating cylinder 5 rotates synchronously in conjunction with it. The first rotating cylinder 5 and the second rotating cylinder 11 achieve contactless driving through permanent magnets (N / S pole permanent magnets alternately arranged in the first and second drive slots 14), thus avoiding mechanical wear.

[0041] Meanwhile, the cotton thread output from the carding machine is initially bundled by the yarn bundler 3 and then passes through the inlet hole formed by the leaf blades 8. When the first rotating drum 5 rotates, the leaf blades 8 generate an airflow in the same direction as the cotton thread, thereby pushing the scattered cotton lint towards the recycling component. In addition, the blades 9 can simultaneously cut the surface hairs of the cotton thread, and the cut cotton lint enters the cavity of the second rotating drum 11 with the airflow.

[0042] The drive rod 24 of the telescopic motor 23 passes through the fixing ring 21 on the arc-shaped plate 19. By controlling the stroke, the position of the arc-shaped plate 19 is adjusted, changing the gap of the pressing groove 27 to adapt to the forming requirements of cotton threads of different thicknesses. At the same time, the ceramic pressing block 26 is wear-resistant, and its concave hole structure guides the cotton thread into the pressing groove 27 to form pressing holes. The second rotating cylinder 11 drives the pressing block 26 to rotate synchronously through the drive rod 24 to ensure that the density of the cotton thread is uniform when it is pressed into a strip.

[0043] The second rotating cylinder 11 drives the arc-shaped plate 19 to rotate synchronously via the drive rod 24. Under the action of the negative pressure fan 30, a negative pressure zone (-0.5~-1.0 kPa) is formed at the cotton collection port 20, which, together with the airflow generated after the rotation of the leaf blades 8, generates a spiral airflow. Driven by the spiral airflow, the cotton fibers are drawn into the first recovery cylinder 17 through the cotton collection port 20.

[0044] When the airflow containing cotton fibers enters the second recycling cylinder 31 through the pipe, the cotton fibers first hit the filter screen 34 and are initially intercepted. At the same time, the circulation pump 35 draws water mist formed by spraying clean water. The water mist can adhere to the surface of the cotton fibers, increasing the weight of the cotton fibers, causing the cotton fibers to stick to the filter screen 34 and be discharged through the exhaust port 32.

[0045] In addition, the first and second recycling cylinders 17 and 31, both made of metal, are grounded via metal wires to discharge static electricity from the cotton fibers. The pressing holes in the ceramic pressing block 26 stabilize the cotton thread path and prevent deviation caused by airflow disturbances.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
