According to actual needs, the optimal number is 4. For good processing, the dust pushes the negative film, and the yarn passes through the threading hole 3012 of the threading frame 3011 on the top of the fixed frame 301. Entering, the yarn passes through the center hole 3041 of the rotating column 304 and goes out from the yarn winding rotating tube 607305, and comes out from the thread outlet 3061 of the folding sheet 306, and then enters through the thread inlet 3062, the servo motor 302 rotates, and passes through the motor conveyor belt 3021. It rotates with the gear sleeve 303 and the rotating column 304, and rotates with the yarn winding rotary tube 607305 and the folding sheet 306. At the same time, it rotates with the yarn, because the position of the folding sheet 306 is in the winding position. On the side of the yarn support 3b, when the servo motor 302 rotates, the yarn collecting piece 312 can be wound by the yarn to achieve the effect of yarn collecting. The yarn does not need to be manually folded, only the servo motor 302 needs to be rotated to make the yarn Winding is performed on the yarn collecting piece 312, and because the yarn collecting piece 312 is flat, the so-called yarn collecting is achieved. After the yarn collecting is completed, the yarn is in conflict, and then rotated by the first rotating motor 402, one of which is The group of plucking transmission assemblies is transmitted, and the two first transmission gears 405 are geared for transmission, respectively carrying another group of plucking transmission assemblies, forming two groups of plucking transmission assemblies, one of which rotates forward and the other reverses. , the yarn feeding transfer wheel 404 in the yarn feeding transfer assembly directly takes down the yarn on the yarn collecting sheet 312 through the hook on the yarn feeding transfer wheel 404, and the two yarn feeding transfer wheels 404 take down the yarn at the same time. The yarn that is wound down is formed and is pressed together in the middle. At the same time, the rotating gears 403 placed on both sides of the yarn feeding transmission wheel 404 cooperate with the teeth to ensure that the yarn does not scatter and pass through the feeding channel. At 4012, the upper and lower extrusion is realized with the guide sheet 411, and the yarn is conveyed and conveyed at the same time, so as to ensure that the yarn transmission can maintain the state of the extrusion, and it has been conveyed to the yarn drawing mechanism 4a, and the yarn drawing mechanism 4a is provided with The guide presser and the presser foot piece cooperate with the conveyor belt to convey the yarn. Because the conveyor belt is connected with the support wheel 410, when the yarn is transferred to the guide presser, it has been squeezed and transmitted by the conveyor belt and the conveyor belt at the same time. , the positioning block 507 is used for protection, the presser foot plate 503 can be prevented from shaking, and then it is also conveyed to the bottom of the sewing machine through the conveyor belt 505, and the presser foot plate 503 and the conveyor belt 505 are pressed and conveyed by the conveyor belt 505 at the same time. The sewing machine performs direct stitching, which is less pre-stitched, and then stitched, which also avoids the waste of silk threads, just in place, and then the yarns pass through the winding and cutting stations 3a1 one by one, and one yarn one yarn is carried out on the fabric. Wire After the suture is finished, the complete dust push negative sheet is in the shape of a long strip, and it is cut at the cutter mechanism 6a, which is cut according to the actual length requirement.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. General changes and substitutions made by those skilled in the art within the scope of the technical solutions of the present invention should be included in the protection scope of the present invention.
