Description

Technical Field

[0001] The present 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 Art

[0002] Recycled cotton is a fiber material made by recycling and reusing waste cotton products. With the enhancement of environmental awareness and technological advancement, more and more research is devoted to developing effective technologies and equipment to recycle these waste cotton fabrics, especially adding a certain proportion of recycled cotton fibers in cotton yarn production, which can not only reduce environmental pressure but also achieve a win-win situation of economic and social benefits.

[0003] In the related technology, the production system includes a cleaning device, which includes a cleaning shell, a blowing assembly, a feed pipe and a discharge pipe. A cleaning cavity is opened on the cleaning shell, and the feed pipe and the discharge pipe are both arranged on the cleaning shell. The feed pipe and the discharge pipe are both connected to the cleaning cavity. The blowing assembly is arranged on the feed pipe, and the blowing assembly is used to pass the recycled cotton from the feed pipe through the cleaning cavity and the discharge pipe in sequence.

[0004] The blowing component blows the regenerated cotton from the inlet to the outlet. At this time, the impurities on the regenerated cotton will not be blown away and will fall into the cleaning chamber. Since there are usually small metal debris in the regenerated cotton, this part of the metal debris is too small and the metal debris is located in the regenerated cotton fibers, making it difficult for the metal debris to be blown away by the blowing component, resulting in the presence of metal debris in the final cotton yarn, which reduces the quality of the cotton yarn and affects the quality of the cotton yarn. Summary of the invention

[0005] In order to improve the problem that metal debris is located in recycled cotton and is difficult to clean, the present application provides a recycled cotton production system and a production process for high-quality recycled cotton yarn.

[0007] By adopting the above technical solution, the metal debris is adsorbed by the adsorbent, so that the metal debris can be moved from the fiber to the adsorbent, and the metal debris in the fiber can be separated from the fiber, thereby reducing the impurities in the recycled cotton fiber, thereby improving the quality of the recycled cotton, and then improving the quality of the cotton yarn.

[0008] Optionally, a accommodating cavity is provided on the cleaning shell, a placement groove is provided on the accommodating cavity, the adsorption piece is arranged in the placement groove, a movable plate is slidably connected to the cleaning shell, the movable plate is used to abut the adsorption piece, a through hole connected to the placement groove is provided on the cleaning shell, the through hole is for metal debris to pass through, a disengagement groove is provided on the through hole, a disengagement spring is provided in the disengagement groove, and a disengagement plate for blocking the through hole is provided on the disengagement spring; when the movable plate is inserted into the through hole, the disengagement plate does not block the through hole.

The movable plate pushes the disengagement plate to move through the metal debris. At this time, the disengagement plate does not block the perforation, allowing the metal debris to detach from the perforation, thereby achieving the cleaning of the metal debris and allowing the adsorption component to adsorb more metal debris; by setting a disengagement spring on the disengagement plate, the disengagement spring drives the disengagement plate to block the perforation, and the recycled cotton is not easy to detach from the cleaning shell from the perforation, so that the recycled cotton and metal debris can be stably located inside the cleaning shell, avoiding the detachment of fibers or metal debris from the perforation.

[0010] Optionally, an operating ring is rotatably connected to the cleaning shell, the movable plate is arranged on the operating ring, and a movable magnet for absorbing metal debris is provided on the operating ring; when the movable plate is inserted into the through hole, the movable magnet absorbs the metal debris through the through hole.

When the operating ring rotates, the operating ring drives the moving plate to move, so that the moving plate is inserted into the perforation, and the moving magnet can be located at the opening of the perforation, so that the moving magnet can absorb metal debris. The staff only needs to clean the metal debris at the moving magnet, and the staff does not need to use the magnet to absorb the metal debris at the perforation again.

[0012] Optionally, a stop bar is provided on the operating ring, and the stop bar is located on the side of the disengagement plate facing the disengagement spring; when the movable plate is not in the placement groove, the stop bar abuts against the surface of the disengagement plate facing the disengagement spring.

[0013] By adopting the above technical solution, the stop bar is located on the side of the detachment plate facing the detachment spring, and the stop bar abuts against the surface of the detachment plate facing the detachment spring, so that the stop bar limits the detachment plate, so that the detachment plate can stably block the perforation, avoiding the detachment plate from failing to block the perforation due to wind blowing, and allowing the fiber to be more stably located in the accommodating cavity.

[0015] By adopting the above technical solution, the staff slides the operating panel to insert the operating panel into the storage slot, and slides the blocking plate to prevent the blocking plate from blocking the cleaning hole, so that the operating panel can separate the impurities from the cleaning hole and the storage slot, thereby facilitating the cleaning of the impurities in the storage slot, avoiding excessive impurities and causing the wind to blow the impurities from the storage slot into the containing chamber, thereby reducing the possibility of impurities moving in the containing chamber.

[0016] Optionally, the blocking plate is arranged on an operating ring, and an operating strip is provided on the operating ring, and the operating strip is used to drive the operating plate to be inserted into the storage slot; when the operating ring rotates, the operating strip drives the operating plate to move, and the blocking plate does not block the cleaning hole.

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

[0018] Optionally, a fixing strip is provided on the operating ring, 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 slot, and the fixing strip is used to drive the fixing plate to block the storage slot; when the fixing plate blocks the storage slot, the operating strip starts to drive the operating plate.

[0019] By adopting the above technical solution, the fixed plate is located on the side of the operating plate away from the bottom wall of the storage slot. When the operating ring rotates, the fixed plate blocks the opening of the storage slot, so that the wind flowing in the accommodating chamber is not easy to flow in the storage slot. At this time, the operating plate can clean the impurities in the storage slot, so that the regenerated cotton can be cleaned when the impurities are cleaned, further improving the cleaning efficiency of the regenerated cotton; at the same time, when the regenerated cotton is cleaned, the impurities can fall to the side of the fixed plate away from the bottom wall of the storage slot.
