Abstract
Description
Technical Field
[0001] This utility model belongs to the field of textile machinery and equipment technology, and more specifically, it relates to cotton yarn combing equipment with auxiliary structures. Background Technology
[0002] In textile processing, cotton yarn combing equipment is mainly used to open, comb, remove impurities, and uniformly mix cotton fibers or chemical fibers to finally produce cotton slivers for subsequent processes. During processing, cotton laps or loose cotton are generally fed into the licker-in rollers by the feed rollers. The licker-in rollers pre-comb and remove 50%-60% of impurities. After the fibers are transferred to the cylinder, they are finely combed with the flats to remove residual small impurities (such as fiber seeds). The combed fibers are then condensed into a cotton web by the doffer, and then formed into cotton slivers through processes such as stripping and pressing.
[0003] The existing application number is CN202020910898.7. This utility model relates to the field of textile equipment technology, and in particular to a carding device for uniform cotton shedding. It includes a traction box, a roller frame, and a fixed frame. The traction box is rotatably connected to an active traction roller, a driven traction roller, and a cylindrical cylinder roller via a rotating shaft. The active and driven traction rollers are located on the same horizontal line, and the cylindrical cylinder roller is located above the active and driven traction rollers. An opening is provided on one side of the traction box, and two roller frames are mirror images of each other in the opening. A traction roller is rotatably connected to the roller frame via a rotating shaft, and a telescopic rod is connected between the roller frame and the wall of the opening. The tops of the two fixed frames are fixedly connected to the inner wall of the top of the traction box. The carding head in this utility model can naturally and closely adhere to the cotton material to comb the cotton, effectively avoiding excessive or insufficient carding pressure, resulting in uniform cotton shedding and ensuring the quality of the carded cotton.
[0004] Based on the above, during the cotton yarn carding process, raw materials often form lumps or clumps due to storage, transportation, and other reasons. Directly putting the raw materials into the carding equipment can easily cause the clumps of cotton yarn to clog the feed inlet and subsequent core carding components such as the licker-in roller and cylinder, resulting in equipment overload and shutdown, which affects production efficiency. Utility Model Content

This addresses the issue that in existing cotton yarn combing processes, raw materials often form lumps or clumps due to storage and transportation.

[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] This invention utilizes a carding drive mechanism. Raw materials are placed inside the carding feed hopper, and the carding drive motor and carding lifting motor are activated. The carding drive motor drives the pre-treatment roller to rotate, which mechanically tears the cotton clumps. Simultaneously, the carding lifting motor drives the carding drive screw to rotate, which in turn moves the carding drive slider up and down, causing the pre-treatment roller to move up and down. First, the carding needles of the pre-treatment roller hook onto the edge fibers of the cotton clump. Simultaneously, the pre-treatment roller vibrates up and down, breaking down the cotton clump into small cotton bundles through "hooking and rubbing." During this process, the hook angle design of the carding needles reduces fiber damage, ensuring that long fibers remain intact. The carded cotton slivers are then screened by a pre-screening plate, achieving pre-treatment of the raw materials, maintaining the cotton bundles in a fluffy state, significantly reducing the probability of material retention, and completely solving the problem of feed inlet blockage caused by cotton clump accumulation in traditional equipment.
[0015] This invention utilizes a screening anti-blocking mechanism. As the combing drive slider moves up and down, it drives the anti-blocking drive rod to move up and down as well. This movement causes the rack and pinion structure of the anti-blocking drive rod to alternately contact the anti-blocking drive gear, which in turn rotates. This rotation of the anti-blocking drive gear then drives the screening anti-blocking component to rotate. Under the action of the anti-blocking reset spring, the screening anti-blocking component oscillates back and forth. This oscillation causes the screening anti-blocking protrusion to repeatedly insert into the screening holes, thus clearing the screening holes, preventing blockage, and ensuring the stable operation of the entire device.

[0028] The carding drive mechanism also includes: a carding drive screw 103 and a carding lifting motor 104; the carding drive screw 103 is a reciprocating screw structure, the carding drive screw 103 is rotatably connected to the front end of the carding feed hopper 2, and the carding drive screw 103 is threadedly connected to the carding drive slider 5; the carding lifting motor 104 is fixedly connected to the upper front end of the carding feed hopper 2, and the carding lifting motor 104 is drively connected to the carding drive screw 103.
[0029] The specific usage and function of this embodiment are as follows: When feeding raw materials, the raw materials are first placed inside the carding feed hopper 2. The carding drive motor 102 and the carding lifting motor 104 are turned on. The carding drive motor 102 drives the pre-treatment roller 3 to rotate. The rotation of the pre-treatment roller 3 realizes the mechanical tearing of the cotton clumps. At the same time, the carding lifting motor 104 drives the carding drive screw 103 to rotate. The rotation of the carding drive screw 103 drives the carding drive slider 5 to move up and down. The up and down movement of the carding drive slider 5 drives the pre-treatment roller 3 to move up and down. First, the carding needles of the pre-treatment roller 3 hook the edge fibers of the cotton clumps. At the same time, the pre-treatment roller 3 vibrates up and down. Through "hooking + rubbing", the cotton clumps are decomposed into small cotton bundles. During this process, the hook angle design of the carding needles can reduce fiber damage and ensure that long fibers remain intact. The carded cotton slivers are screened by the pre-screening plate 4, realizing the pre-treatment of raw materials, keeping the cotton bundles in a fluffy state, significantly reducing the probability of material retention, and completely solving the problem of feed inlet blockage caused by cotton clump accumulation in traditional equipment.

[0035] The specific usage and function of this embodiment are as follows: During the pretreatment of raw materials, as the combing drive slider 5 moves up and down, the combing drive slider 5 moves up and down, causing the anti-blocking drive rod 406 to move up and down. The up and down movement of the anti-blocking drive rod 406 causes the rack structure of the anti-blocking drive rod 406 to alternately contact the anti-blocking drive gear 405, which is driven to rotate. The rotation of the anti-blocking drive gear 405 causes the screening anti-blocking component 401 to rotate. Under the action of the anti-blocking reset spring 402, the screening anti-blocking component 401 swings back and forth. The back and forth swing of the screening anti-blocking component 401 causes the screening anti-blocking protrusion 404 to repeatedly insert into the interior of the screening hole 403, thereby clearing the screening hole 403, preventing the screening hole 403 from becoming blocked, and ensuring the stable operation of the entire device.
