Description

Technical Field

[0001] This application relates to the technical field of recycled cotton, and in particular to a recycled cotton production system and a production process for high-quality recycled cotton yarn. Background Technology

[0002] Recycled cotton is a fiber material made by recycling and reusing waste cotton products. With the increasing awareness of environmental protection and the advancement of technology, more and more research is dedicated to developing effective technologies and equipment to recycle these waste cotton fabrics. In particular, adding a certain proportion of recycled cotton fiber to cotton yarn production can reduce environmental pressure and achieve a win-win situation of economic and social benefits.

[0003] In the related technology, the production system includes cleaning equipment, which includes a cleaning shell, an air blowing assembly, a feeding pipe, and a discharging pipe. The cleaning shell has a cleaning chamber. The feeding pipe and the discharging pipe are both located on the cleaning shell and are connected to the cleaning chamber. The air blowing assembly is located on the feeding pipe and is used to push the recycled cotton from the feeding pipe through the cleaning chamber and the discharging pipe in sequence.

[0004] The air blowing component blows the recycled cotton from the inlet to the outlet. At this time, the impurities on the recycled cotton will not be blown away and will fall into the cleaning chamber. Since there are usually small metal fragments in the recycled cotton, these metal fragments are too small and located in the recycled cotton fibers, making it difficult for the air blowing component to blow them away. As a result, the final cotton yarn contains metal fragments, which reduces the quality of the cotton yarn and affects its quality. Summary of the Invention

[0005] To address the problem of metal debris being difficult to remove from recycled cotton, this application provides a recycled cotton production system and a production process for high-quality recycled cotton yarn.

[0006] This application provides a recycled cotton production system and a high-quality recycled cotton yarn production process, which adopts the following technical solution: A recycled cotton production system includes a cleaning device, which includes a cleaning shell, a blowing assembly, a feeding pipe, and a discharging pipe. The feeding pipe and the discharging pipe are both located on the cleaning shell. The blowing assembly is located on the feeding pipe and is used to move the recycled cotton from the feeding pipe to the discharging pipe. The cleaning shell is provided with an adsorption element that can adsorb metal debris.

[0007] By adopting the above technical solution, metal debris is adsorbed by the adsorption element, allowing the metal debris to move from the fiber to the adsorption element, thus detaching the metal debris from the fiber, reducing impurities in the recycled cotton fiber, improving the quality of the recycled cotton, and consequently improving the quality of the cotton yarn.

[0008] Optionally, the cleaning shell has a receiving cavity, and the receiving cavity has a placement groove. The adsorption element is disposed in the placement groove. A movable plate is slidably connected to the cleaning shell. The movable plate is used to abut the adsorption element. The cleaning shell has a through hole communicating with the placement groove. The through hole allows metal debris to pass through. A release groove is formed in the through hole. A release spring is provided in the release groove. A release plate is provided on the release spring for sealing the through hole. When the movable plate is inserted into the through hole, the release plate does not seal the through hole.

[0009] By adopting the above technical solution, the operator drives the moving plate to move and insert it into the placement slot. At this time, the moving plate abuts against the adsorption component, and the moving plate can move the metal debris on the adsorption component until the moving plate inserts into the perforation. The metal debris is located between the moving plate and the release plate. The moving plate pushes the release plate to move through the metal debris. At this time, the release plate does not block the perforation, allowing the metal debris to be removed from the perforation, thus cleaning the metal debris and allowing the adsorption component to adsorb more metal debris. By setting a release spring on the release plate, the release spring drives the release plate to block the perforation, making it difficult for the recycled cotton to be removed from the cleaning shell from the perforation. This allows the recycled cotton and metal debris to be stably located inside the cleaning shell, preventing fibers or metal debris from being removed from the perforation.

[0010] Optionally, an operating ring is rotatably connected to the cleaning shell, and a movable plate is disposed on the operating ring. The operating ring is provided with a movable magnet for adsorbing metal debris. When the movable plate is inserted into the perforation, the movable magnet adsorbs metal debris through the perforation.

[0011] By adopting the above technical solution, a movable plate is set on the operating ring. When the operating ring rotates, it drives the movable plate to move, so that the movable plate can be inserted into the perforation and the movable magnet can be located at the opening of the perforation. This allows the movable magnet to attract metal debris. Afterwards, the staff only needs to clean the metal debris at the movable magnet. The staff does not need to hold the magnet again to attract the metal debris at the perforation.

[0012] Optionally, the operating ring is provided with a stop strip, which is located on the side of the release plate facing the release spring; when the moving plate is not in the placement slot, the stop strip abuts against the surface of the release plate facing the release spring.

[0013] By adopting the above technical solution, the stop strip is located on the side of the release plate facing the release spring, and the stop strip abuts against the surface of the release plate facing the release spring, so that the stop strip limits the release plate, allowing the release plate to stably seal the perforation, preventing the release plate from failing to seal the perforation due to wind blowing, and allowing the fiber to be more stably located in the receiving cavity.

[0014] Optionally, a storage slot is provided on the inner wall of the receiving cavity near the ground, and a cleaning hole is provided in the storage slot. A sealing plate for sealing the cleaning hole is slidably connected to the cleaning shell, and an operating plate for inserting into the storage slot is slidably connected to the cleaning shell. When the operating plate is inserted into the storage slot, impurities can be removed from the cleaning hole.

[0015] By adopting the above technical solution, the operator slides the control panel, inserts it into the storage tank, and slides the sealing plate to leave the cleaning hole unblocked. This allows the control panel to remove impurities from the cleaning hole into the storage tank, thus facilitating the cleaning of impurities in the storage tank. This prevents excessive impurities from being blown from the storage tank into the receiving cavity by the airflow, reducing the possibility of impurities moving within the receiving cavity.

[0016] Optionally, the sealing plate is disposed on the operating ring, and the operating ring is provided with an operating bar. The operating bar is used to drive the operating plate to be inserted into the storage slot. When the operating ring rotates, the operating bar drives the operating plate to move, and the sealing plate does not block the cleaning hole.

[0017] By adopting the above technical solution, when the operating ring rotates, it drives the operating bar to move, which in turn drives the operating plate to move. At this time, the sealing plate does not block the cleaning hole, so that the operator does not need to move the operating plate and the sealing plate sequentially, reducing the operator's operation steps and speeding up the cleaning of impurities.

[0018] Optionally, the operating ring is provided with a fixing strip, and a fixing plate is slidably connected to the cleaning shell. The fixing plate is located on the side of the operating plate away from the bottom wall of the storage tank. The fixing strip is used to drive the fixing plate to block the storage tank. When the fixing plate blocks the storage tank, the operating strip starts to drive the operating plate.

[0019] By adopting the above technical solution, with the fixing plate located on the side of the operating plate away from the bottom wall of the storage tank, when the operating ring rotates, the fixing plate blocks the opening of the storage tank, making it difficult for the air flowing in the receiving cavity to flow in the storage tank. At this time, the operating plate can clean the impurities in the storage tank, so that the recycled cotton can be cleaned while the impurities are being cleaned, further improving the cleaning efficiency of the recycled cotton. At the same time, when the recycled cotton is being cleaned, the impurities can fall to the side of the fixing plate away from the bottom wall of the storage tank. When the fixing plate is reset, the impurities can move from the fixing plate into the storage tank.

[0020] Optionally, the operating ring is provided with a receiving block, and the receiving block has a receiving hole; when the operating board is driven to be inserted into the storage slot, the receiving hole is connected to the cleaning hole.

[0021] By adopting the above technical solution, the cleaning hole is connected to the receiving hole, allowing impurities to move from the cleaning hole to the receiving hole, so that the operating ring can store impurities. This eliminates the need for staff to clean the ring each time, thereby reducing their workload.

[0022] A production process for high-quality recycled cotton yarn also includes S1, open cotton, open cotton and blended cotton; S2, combing, opening individual fibers, removing impurities, untangling lint, removing broken fibers, and orienting fibers; S3, parallel lines, balanced line shape, parallel lines, mixed lines, dust removal; S4, spinning, the process of weaving fibers into yarn; The recycled cotton production system is used in the cotton cleaning step of the aforementioned cleaning process.

[0023] In summary, this application includes at least one of the following beneficial technical effects: The metal debris is adsorbed by an adsorption element, allowing it to move from the fiber to the adsorption element and detach from the fiber. This reduces impurities in the recycled cotton fiber, improves the quality of the recycled cotton, and consequently improves the quality of the cotton yarn.

[0024] The movable plate is set on the operating ring. When the operating ring rotates, it drives the movable plate to move, so that the movable plate can be inserted into the perforation. This allows the movable magnet to be located at the opening of the perforation, enabling the movable magnet to attract metal debris. Afterwards, the staff only needs to clean the metal debris at the movable magnet, and the staff no longer needs to use the magnet to attract metal debris at the perforation.

[0029] Reference Figure 2 The blowing assembly 2 includes a fan, and a blowing duct 31 is provided on the feed pipe 3. The fan is fixedly connected inside the blowing duct 31. The fan can drive the fibers to pass through the feed pipe 3, the cleaning shell 1 and the discharge pipe 4 in sequence, and impurities in the fibers can fall off in the cleaning shell 1.

[0030] Reference Figure 2 An adsorption element 12 is provided on the outer surface of the cleaning shell 1. The adsorption element 12 is used to adsorb metal debris. The adsorption element 12 includes an electromagnet, which is fixedly connected to the outer surface of the cleaning shell 1. The electromagnet is located between the feed pipe 3 and the discharge pipe 4, and the electromagnet is capable of adsorbing metal debris.

[0031] The implementation principle of Example 1 is as follows: the quality of recycled cotton is improved by using an electromagnet to attract metal debris. Example 2

[0032] Reference Figure 3 and Figure 4 The difference between this embodiment and Embodiment 1 is that an operating ring 5 is rotatably connected to the outer surface of the cleaning shell 1, and the operating ring 5 extends circumferentially along the cleaning shell 1. The cleaning shell 1 includes a first part, a second part, and a third part, which are integrally formed, with the second part located between the first and third parts. The second part is frustum-shaped, while the first and third parts are cylindrical, with the diameter of the first part being larger than that of the third part. A receiving cavity 11 is provided inside the cleaning shell 1, which connects to the feed pipe 3 and the discharge pipe 4. A storage groove 13 is provided on the inner wall of the receiving cavity 11 near the ground, for impurities to fall into, and the storage groove 13 is located on the third part.

[0033] Reference Figure 5 An operation hole 14 communicating with a storage tank 13 is provided on the outer surface of the cleaning shell 1. An operation plate 141 is slidably connected inside the operation hole 14 and can abut against the bottom wall of the storage tank 13. A cleaning hole 15 communicating with the storage tank 13 is provided on the outer surface of the cleaning shell 1, and the cleaning hole 15 and the operation hole 14 are aligned. When the operation plate 141 is inserted into the storage tank 13, impurities can be removed from the cleaning hole 15.

[0034] Reference Figure 3 and Figure 5 A receiving block 57 is fixedly connected to the inner wall of the operating ring 5. The receiving block 57 has a receiving hole 571 for storing impurities and can communicate with the cleaning hole 15. A blocking plate 51 is fixedly connected to the receiving block 57. The blocking plate 51 is used to block the cleaning hole 15 and extends along the bending direction of the operating ring 5.

[0035] Reference Figure 3 and Figure 5 A first magnet 143 is fixedly connected to the operation plate 141, and a second magnet 521 is fixedly connected to the inner wall of the operation ring 5. The second magnet 521 attracts the first magnet 143. When the second magnet 521 attracts the first magnet 143, the operation plate 141 disengages from the storage slot 13 and blocks the operation hole 14. An operation bar 52 is fixedly connected to the inner wall of the operation ring 5. An operation ramp 142 is formed on the end face of the first magnet 143. The distance between the operation ramp 142 and the operation ring 5 gradually decreases along the rotation direction of the operation ring 5, and the operation ramp 142 is located on the movement path of the operation bar 52.

[0036] Reference Figure 3 and Figure 5When the operating ring 5 rotates, the operating bar 52 pushes the operating plate 141 to move via the operating ramp 142, causing the operating plate 141 to push impurities towards the cleaning hole 15 within the storage tank 13. At this time, the sealing plate 51 does not seal the cleaning hole 15 as the operating ring 5 rotates, allowing impurities to detach from the cleaning hole 15. When the operating ring 5 resets, the second magnet 521 attracts the first magnet 143, causing the second magnet 521 to move the operating plate 141, which then seals the operating hole 14.

[0037] Reference Figure 5 A fixing hole 16 communicating with the receiving cavity 11 is provided on the outer surface of the cleaning shell 1. A fixing plate 161 is slidably connected inside the fixing hole 16. The fixing hole 16 is located on the side of the operating hole 14 away from the bottom wall of the storage tank 13. A third magnet 163 is fixedly connected to the fixing plate 161, and a fourth magnet 531 is fixedly connected to the inner wall of the operating ring 5. The fourth magnet 531 is located on the side of the second magnet 521 away from the ground, and the fourth magnet 531 can attract the third magnet 163. When the fourth magnet 531 attracts the third magnet 163, the fixing plate 161 detaches from the storage tank 13, and at this time the sealing plate 51 seals the cleaning hole 15.

[0038] Reference Figure 5 A fixing inclined surface 162 is provided on the end face of the third magnet 163 away from the fixing plate 161, and a fixing strip 53 is fixedly connected to the inner wall of the operating ring 5. The distance between the fixing inclined surface 162 and the operating ring 5 decreases along the rotation direction of the operating ring 5, and the fixing inclined surface 162 is located on the moving path of the fixing strip 53.

[0039] Reference Figure 5 When the operating ring 5 rotates, the fixing bar 53 pushes the fixing plate 161 to move through the fixing inclined surface 162 until the fixing plate 161 completely blocks the opening of the storage tank 13. At this time, the operating bar 52 abuts against the operating inclined surface 142, and the sealing plate 51 does not block the cleaning hole 15. When the operating ring 5 resets, the sealing plate 51 blocks the cleaning hole 15, and then the fourth magnet 531 attracts the third magnet 163, allowing the fixing plate 161 to detach from the storage tank 13, so that impurities away from the ground can fall into the storage tank 13.

[0040] Reference Figure 4 and Figure 6 The inner wall of the receiving cavity 11 is provided with a placement groove 17, and an adsorption member 12 is fixedly connected to the bottom wall of the placement groove 17. The outer surface of the cleaning shell 1 is provided with a moving hole 18 and a through hole 19 that communicate with the placement groove 17, and both the moving hole 18 and the through hole 19 extend along the length direction of the placement groove 17.

A release plate 193 is provided inside the release groove 191, and the end face of the release spring 192 away from the bottom wall of the release groove 191 is fixedly connected to the release plate 193. The release spring 192 drives the release plate 193 to protrude out of the release groove 191, at which time the release plate 193 can block the through hole 19.

[0042] Reference Figure 6 and Figure 7 A stop strip 55 is fixedly connected to the inner wall of the operating ring 5. A stop hole 194 communicating with the release groove 191 is opened on the outer surface of the cleaning shell 1, through which the stop strip 55 passes. The stop strip 55 is located on the side of the release plate 193 facing the release spring 192. When the moving plate 54 is located in the moving hole 18, the stop strip 55 abuts against the surface of the release plate 193 facing the release spring 192. At this time, the release plate 193 blocks the release hole and the moving plate 54 blocks the moving hole 18. A movable magnet 56 is fixedly connected to the inner wall of the operating ring 5. The movable magnet 56 can attract metal debris at the through hole 19.

[0043] Reference Figure 6 and Figure 7 When the operating ring 5 rotates, the operating ring 5 drives the moving plate 54 to be inserted into the placement groove 17. At this time, the moving plate 54 abuts against the adsorption member 12 until the moving plate 54 is inserted into the perforation 19. The moving plate 54 drives the metal debris to move into the perforation 19. At this time, the detachment plate 193 does not block the perforation 19. The moving magnet 56 is located at the perforation 19 and the moving magnet 56 adsorbs the metal debris.

[0044] Reference Figure 6 and Figure 7 When the operating ring 5 is reset, the moving plate 54 disengages from the placement slot 17, the moving plate 54 blocks the moving hole 18, the disengagement spring 192 drives the disengagement plate 193 to block the through hole 19, and the stop strip 55 abuts against the surface of the disengagement plate 193 toward the disengagement spring 192, so that the stop strip 55 restricts the movement of the disengagement plate 193.

[0045] Reference Figure 5 , Figure 6 and Figure 7 When the operating ring 5 rotates, the moving plate 54 is inserted into the placement slot 17. At this time, the fixed plate 161 blocks the opening of the storage slot 13. As the operating ring 5 continues to rotate, the moving plate 54 is inserted into the through hole 19. At this time, the blocking plate 51 does not block the cleaning hole 15, and the operating plate 141 slides in the storage slot 13, so that the cleaning of impurities in the storage slot 13 and the cleaning of metal debris in the placement slot 17 are carried out simultaneously, reducing the number of operations required by the staff.

[0046] The implementation principle of Example 2 is as follows: When the operating ring 5 rotates, the operating ring 5 drives the moving plate 54 to be inserted into the placement slot 17. At this time, the fixing bar 53 pushes the fixing plate 161 to move, so that the fixing plate 161 blocks the opening of the storage slot 13 until the moving plate 54 is inserted into the through hole 19. At this time, the detachment plate 193 does not block the through hole 19, so that the metal debris is attracted from the through hole 19 by the moving magnet 56. At the same time, the operating bar 52 drives the operating plate 141 to move, so that the operating plate 141 moves in the storage slot 13, and the sealing plate 51 does not block the cleaning hole 15, so that the impurities can move from the cleaning hole 15 to the receiving hole 571.
