The same rotating rod 15 is provided in the two circular holes. Two fixing rings 17 are fixedly sleeved on the outer side of the rotating rod 15. A plurality of beating rods 18 are fixedly installed on the outer sides of the two fixing rings 17. The plurality of beating rods 18 are all L-shaped. The other ends of the multiple beating rods 18 are all set in an arc shape, and the outer side of the rotating rod 15 is fixedly sleeved with a first pulley 19. A through hole is opened on the top side of the bracket 14, and two mounting plates 20 are fixedly installed on the top side of the bracket 14. A linkage component is set between the two mounting plates 20 and the first pulley 19. The top side and one side of the bottom plate 1 are respectively provided with a winding component and a dust collection component. The linkage component includes a second motor 21 fixedly installed on one side of a mounting plate 20, and the output end of the second motor 21 rotates through a The mounting plate 20 is rotatably connected to one side of the other mounting plate 20, and a second pulley 22 is fixedly sleeved on the outer side of the output end of the second motor 21, and the same belt 23 is provided between the second pulley 22 and the first pulley 19, and the second motor 21 drives the second pulley 22 to rotate. Because the second pulley 22 and the first pulley 19 share the same belt 23, under the transmission action of the belt 23, the first pulley 19 synchronously drives the rotating rod 15 to rotate, thereby causing the two fixed rings 17 fixedly sleeved on the outer side of the rotating rod 15 to rotate synchronously. Subsequently, multiple beating rods 18 fixedly installed on the outer sides of the two fixed rings 17 beat the finished yarn product, thereby beating up the dust attached to the finished yarn product, and in the process of beating, some impurities such as metal debris can also be beaten off from the finished yarn product. When beating, the dust collection component can be used to absorb these impurities and store them in the collection box 8, so as to avoid some metal fragments from damaging the finished yarn product in the subsequent winding process.

[0023] Specifically, the winding assembly includes two fixed plates 3 fixedly installed on the top side of the base plate 1, and a first motor 4 is fixedly installed on one side of one fixed plate 3. The output end of the first motor 4 rotates through one fixed plate 3 and is rotatably connected to one side of the other fixed plate 3. A winding wheel 5 is fixedly sleeved on the outer side of the output end of the first motor 4. By providing the winding wheel 5, after a part of the finished yarn product is dusted, the clean area is fixedly wound on the winding wheel 5, and then the first motor 4 is started to achieve dust removal and winding at the same time.

The dust box 13 absorbs the dust knocked off the finished yarn products, thereby preventing people from suffering damage to their bodies after long-term inhalation of dust. It can also prevent debris from adhering to the finished yarn products, which will affect the subsequent winding work. The dust and debris sucked in by the top dust box 12 and the bottom dust box 13 will enter the collection box 8 through the diversion pipe 11 for storage, which is convenient for subsequent unified processing. A filter plate 10 is fixedly installed on the inner wall of the collection box 8, which can block the dust and prevent dust from entering the fan 7 and damaging the internal parts of the fan 7, thereby causing the fan 7 to stop running.

[0027] During use: by placing the finished product between the top dust collection box 12 and the bottom dust collection box 13, and then starting the second motor 21 to drive the second pulley 22 to rotate, and because the second pulley 22 and the first pulley 19 share the same belt 23, under the transmission action of the belt 23, the first pulley 19 synchronously drives the rotating rod 15 to rotate, and then the two fixed rings 17 fixedly sleeved on the outside of the rotating rod 15 rotate synchronously, and then the multiple beating rods 18 fixedly installed on the outside of the two fixed rings 17 are used to beat the finished yarn products, thereby slapping the dust attached to the finished yarn products. In the process of the operation of the second motor 21, the fan 7 drives the top dust collection box 12 and the bottom dust collection box 13 to absorb the dust falling on the finished yarn products, thereby preventing people from inhaling dust for a long time. It will cause damage to the body, and further prevent debris from adhering to the finished yarn products, which will affect the subsequent winding work. The dust and debris sucked into the top dust box 12 and the bottom dust box 13 will enter the collection box 8 through the diversion pipe 11 for storage, which is convenient for subsequent unified treatment. A filter plate 10 is fixedly installed on the inner wall of the collection box 8 to block the dust and prevent dust from entering the fan 7, which will damage the internal parts of the fan 7, thereby causing the fan 7 to stop running. After a part of the finished yarn product area has been dusted, the clean area is fixedly wound on the winding wheel 5 and the first motor 4 is then started to achieve dust removal and winding at the same time. When all the finished yarn products have been dusted, the rolled finished yarn products are taken away and the dust removal work of the next batch of finished yarn products can be carried out.
