Description

An anti-twist device for ultra-fine denier porous polyester Technical Field

[0001] This utility model relates to the field of anti-twist devices, specifically an anti-twist device for ultra-fine denier porous polyester. Background Technology

[0002] In the texturing process of ultra-fine denier porous polyester DTY yarn, an untwisted yarn undergoes a twisting process. To prevent the twist from being transmitted to the feed inlet, an anti-twist device needs to be added near the heating box and the feed inlet.

[0003] According to a public notice (CN216304075U) of an anti-twist device for ultra-fine denier porous polyester DTY, the above application includes a first fixed plate and a second fixed plate. The bearing is coaxially arranged with the anti-twist device body, and the inner ring of the bearing is fixedly connected to a support plate. A horizontal adjustment device is provided on the side of the support plate away from the anti-twist device body. The horizontal adjustment device includes a fixed block and several positioning and fixing structures for adjusting the horizontality of the anti-twist device body. The fixed block is ball-jointed to the support plate. A blind hole is opened on the side of the fixed block away from the anti-twist device body. A support shaft is rotatably connected in the blind hole. This realizes the adjustment of the anti-twist channel gap between the two star wheels, and indirectly controls the anti-twist strength of the anti-twist device body.

[0004] However, in actual use, when adjusting the anti-twist channel gap between the two star wheels, waste yarn generated during anti-twist can easily adhere to the gap between the star wheels and the outer wall, which can easily cause deformation deviation during subsequent anti-twist. In view of this, we propose an anti-twist device for ultra-fine denier porous polyester. Summary of the Invention

[0005] The purpose of this invention is to provide an anti-twist device for ultra-fine denier porous polyester to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a twist stopper for ultra-fine denier porous polyester, comprising a mounting shaft, an mounting plate detachably mounted on the outer wall of the mounting shaft, an anti-jamming component provided on the outer wall of the mounting plate, the anti-jamming component comprising a first protrusion tooth fixedly connected to the outer wall of the mounting plate, a threaded torsion bar rotatably mounted on the inner wall of the mounting plate, a fixed plate threadedly connected to the outer wall of the threaded torsion bar, a second protrusion tooth fixedly connected to the outer wall of the fixed plate, and a limit guide sleeve fixedly connected to the outer wall of the fixed plate;

[0007] A movable limiting sleeve is fixedly connected to the outer wall of a threaded torsion bar. A flexible swing rod is fixedly connected to the outer wall of the threaded torsion bar. An antistatic comb tooth is fixedly connected to the outer wall of the flexible swing rod. An arc-shaped block is fixedly connected to the outer wall of the antistatic comb tooth.

[0008] Preferably, the inner wall of the limiting guide sleeve is slidably connected to the outer wall of the movable limiting sleeve, and the limiting guide sleeve and the movable limiting sleeve are adapted to each other, so that the limiting guide sleeve and the movable limiting sleeve can make stable relative displacement.

[0009] Preferably, the number of antistatic comb teeth is several, and the several antistatic comb teeth are arranged in a linear array on the outer wall of the flexible swing rod, so that the antistatic comb teeth can smoothly wind up the waste silk material they come into contact with.

[0010] Preferably, the center line of the limiting guide sleeve and the center line of the movable limiting sleeve are on the same straight line, so that the limiting guide sleeve and the movable limiting sleeve can be kept on the same horizontal line.

[0011] Preferably, the outer wall of the limiting guide sleeve is provided with a triggering component, the triggering component includes an arc-shaped top block, the arc-shaped top block is fixedly connected to the outer wall of the limiting guide sleeve, the outer wall of the flexible swing rod is fixedly connected to a fixing cross plate, and the outer wall of the fixing cross plate is fixedly connected to a pressure-bearing arc block.

[0012] Preferably, the number of arc-shaped top blocks is several, and the several arc-shaped top blocks are arranged in a circumferential array on the outer wall of the limiting guide sleeve, so that the arc-shaped top blocks can periodically squeeze the pressure arc block.

[0013] Compared with the prior art, this utility model provides an anti-twist device for ultra-fine denier porous polyester, which has the following beneficial effects:

[0014] 1. This anti-twist device for ultra-fine denier porous polyester rotates the threaded torsion bar, causing the fixed disc and the second tooth to shift, thus adjusting the gap. Rotating the threaded torsion bar also causes the flexible swing arm to shift synchronously, allowing the antistatic comb teeth and the arc-shaped block to rotate relative to the first and second teeth. This results in the arc-shaped block periodically striking the first and second teeth, shaking off the waste yarn adhering to their surfaces and scraping away the waste yarn inside, ultimately ensuring stability during anti-twist.

[0015] 2. In this anti-twist device for ultra-fine denier porous polyester, when the threaded torsion bar is rotated to make the toughness rocker arm move synchronously, the pressure arc block set on the fixed horizontal plate is squeezed by the arc-shaped top block on the limiting guide sleeve, causing the toughness rocker arm to deform. This deformation, in turn, causes the arc block to better periodically touch the first and second protrusions through vibration, allowing the attached waste yarn to fall off better, thereby further improving the overall practicality.

[0024] As shown in Figures 1-7, this utility model provides a technical solution: an anti-twist device for ultra-fine denier porous polyester, including a mounting shaft 1. The outer wall of the mounting shaft 1 is detachably mounted on a mounting plate 2. The outer wall of the mounting plate 2 is provided with an anti-jamming component 3. The anti-jamming component 3 includes a first protrusion 301, which is fixedly connected to the outer wall of the mounting plate 2. A threaded torsion bar 302 is rotatably mounted on the inner wall of the mounting plate 2. A fixing plate 303 is threadedly connected to the outer wall of the threaded torsion bar 302. A second protrusion 304 is fixedly connected to the outer wall of the fixing plate 303. A limit guide sleeve 305 is fixedly connected to the outer wall of the fixing plate 303.

[0025] Furthermore, the movable limiting sleeve 306 is fixedly connected to the outer wall of the threaded torsion bar 302, the outer wall of the threaded torsion bar 302 is fixedly connected to the flexible rocker arm 307, the outer wall of the flexible rocker arm 307 is fixedly connected to the antistatic comb teeth 308, and the outer wall of the antistatic comb teeth 308 is fixedly connected to the arc-shaped block 309.

[0026] In the embodiments of this utility model, the inner wall of the limiting guide sleeve 305 is slidably connected to the outer wall of the movable limiting sleeve 306, and the limiting guide sleeve 305 and the movable limiting sleeve 306 are adapted to each other, so that the limiting guide sleeve 305 and the movable limiting sleeve 306 can make stable relative displacement. The number of antistatic comb teeth 308 is several, and the several antistatic comb teeth 308 are arranged in a linear array on the outer wall of the flexible swing rod 307, so that the antistatic comb teeth 308 can smoothly wind the contacted wire waste. The center line of the limiting guide sleeve 305 and the center line of the movable limiting sleeve 306 are on the same straight line, so that the limiting guide sleeve 305 and the movable limiting sleeve 306 can be kept on the same horizontal line.

[0027] The outer wall of the limiting guide sleeve 305 is provided with a trigger component 4. The trigger component 4 includes an arc-shaped top block 401, which is fixedly connected to the outer wall of the limiting guide sleeve 305. The outer wall of the flexible swing rod 307 is fixedly connected with a fixed horizontal plate 402, and the outer wall of the fixed horizontal plate 402 is fixedly connected with a pressure arc block 403. The number of arc-shaped top blocks 401 is several, and the several arc-shaped top blocks 401 are arranged in a circumferential array on the outer wall of the limiting guide sleeve 305, so that the arc-shaped top blocks 401 can periodically squeeze the pressure arc block 403.

[0028] In this invention, before adjusting the anti-twisting channel gap between protruding tooth 301 and protruding tooth 304, the mounting shaft 1 and mounting plate 2 can be fixed, and then the threaded torsion bar 302 can be rotated, thereby causing the fixed plate 303 and protruding tooth 304 to move and the gap can be adjusted. When the threaded torsion bar 302 is rotated, the flexible swing bar 307 will move synchronously, thereby allowing the antistatic comb 308 and the arc block 309 to rotate relative to protruding tooth 301 and protruding tooth 304. Finally, the arc block 309 can periodically strike protruding tooth 301 and protruding tooth 304, so that the waste yarn attached to the surface of protruding tooth 301 and protruding tooth 304 can be shaken off, and the waste yarn attached inside can be scraped and rolled up by the rotating antistatic comb 308, thus ensuring the stability during anti-twisting.

[0029] When the threaded torsion bar 302 is rotated to make the flexible rocker arm 307 move synchronously, the pressure arc block 403 set on the fixed horizontal plate 402 will be squeezed by the arc-shaped top block 401 on the limiting guide sleeve 305, causing the flexible rocker arm 307 to deform. In turn, the arc block 309 can better periodically touch the first tooth 301 and the second tooth 304 through vibration, so that the attached waste wire can be better removed.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
