[0051] In a specific implementation, a driving motor is arranged on the outside of the fixed cylinder 2, and the output shaft of the driving motor is fixedly connected to the driving gear 206. The driving gear 206 drives the meshing gear plate 201 to rotate, so that the grinding piece on the grinding frame 202 on one side of the gear plate 201 rotates with the gear plate 201, and makes an annular contact with the yarn, thereby improving the cleaning effect on the outside of the yarn, and through the transmission of the transmission member, one of the transmission wheels 2021 rotates, and when one of the transmission wheels 2021 is turned, it drives the grinding belt 2022 to drive, thereby further improving the treatment of burrs on the outside of the yarn;

[0052] When the grinding frame 202 rotates the gear plate 201, the first gear 2029 in the transmission member meshes with the inner gear ring 203 provided on the inner wall of the fixed cylinder 2, so that the first gear 2029 drives the fixedly connected second pulley 2024 to rotate, and the second pulley 2024 drives the third pulley 2025 and the first pulley 2023 to rotate through the belt, thereby ensuring that one of the transmission wheels 2021 rotates, achieving the above-mentioned cleaning effect of the grinding belt 2022;

[0054] like Figure 3As shown, in this embodiment, a dust suction disc 207 is arranged inside the fixed cylinder 2 close to the grinding piece, a dust suction port is opened on one side of the dust suction disc 207, and a docking joint 208 is arranged on the outer side of the dust suction disc 207. The docking joint 208 is connected to an external dust suction device by setting a dust suction pipe.

[0055] During specific implementation, when the polishing belt 2022 contacts the yarn to clean the fluff, a large amount of fluff will adhere to the surface of the polishing belt 2022, so a scraper 205 is provided, and the scraper 205 is fixedly connected to the polishing frame 202. The scraper 205 contacts the polishing belt 2022 to scrape off the fluff, and in order to make the fluff fall back to the outside of the yarn, a dust suction plate 207 is provided, and the dust suction plate 207 absorbs the cleaned fluff through the dust suction port.

[0056] like Figure 6 As shown, embodiment three: the elastic member includes a fixed side plate 306 fixedly connected to both sides of the tensioning frame 3, a second telescopic rod 303 and a second spring 304 are fixedly connected between the fixed side plate 306 and the sliding block 302, the second spring 304 is sleeved on the outside of the second telescopic rod 303, and the touch switch 305 is fixedly connected to the top of the fixed side plate 306.

[0057] In specific implementation, when the yarn passes through the bottom of the tensioning wheel 301, the elastic members on both sides of the tensioning wheel 301 are used to tension and adjust the yarn to ensure that the yarn is always in a tensioned state. When the yarn breaks due to an accident, the tensioning wheel 301 loses the upward force of the yarn, and the second spring 304 between the sliding block 302 and the fixed side plate 306 is used to quickly pull the sliding block 302 down, so that the sliding block 302 contacts the touch switch 305 below, and the touch switch 305 is triggered, so that the locking members on the two locking frames 4 lock the yarn to prevent the yarn from falling off and requiring personnel to rethread.

[0058] like Figures 7 and 8 As shown, in this embodiment, the locking member includes two clamping frames 402 arranged inside the locking frame 4, the two clamping frames 402 are arranged opposite to each other, and penetrate the locking frame 4 and are rotatably connected to the locking frame 4, the two clamping frames 402 are fixedly connected with the second gear 403 at both ends, and the two second gears 403 on the same side are provided with a connecting plate 406 on one side, the two connecting plates 406 are respectively fixedly connected to the telescopic ends of the two second electric rods 405, and the outer sides of the two connecting plates 406 are fixedly connected with racks 404, and the two racks 404 are respectively meshed and connected with the two second gears 403.

[0059] In specific implementation, when the second electric rod 405 pulls the connecting plate 406 down, the connecting plate 406 drives the rack 404 fixedly connected on the outside to descend together, and at this time the rack 404 drives the second gear 403 meshingly connected on the outside to rotate, and when the second gear 403 rotates, it drives the fixedly connected clamping frame 402 to rotate, so that one end of the two clamping frames 402 inside the locking frame 4 rotates toward the rotating wheel 401, and the yarn is fixed on the outside of the rotating wheel 401, so that the yarn is quickly locked to ensure that the yarn falls off from the device.

[0060] like Figures 9 and 10 As shown, in this embodiment, a plurality of placement grooves 4011 are provided on the outer side of the rotating wheel 401, and a baffle 4014 is provided inside each of the placement grooves 4011. A ejection block 4015 is fixedly connected to the top of the baffle 4014, and a plurality of third springs 4016 are fixedly connected between the bottom of the baffle 4014 and the rotating wheel 401. A connecting pipe 4012 is fixedly connected inside the rotating wheel 401, and the connecting pipe 4012 passes through the locking frame 4 and is rotatably connected to the locking frame 4. A flow groove 4017 for communication is provided between the connecting pipe 4012 and the placement groove 4011.

[0061] Two storage frames 501 are fixedly connected on both sides of the locking frame 4, and extrusion plates 503 are slidably arranged inside the two storage frames 501. A pushing rod 502 is fixedly connected to the bottom of the connecting plate 406. The pushing rod 502 penetrates the storage frame 501 and is slidably connected to the storage frame 501. The storage frame 501 is filled with liquid. One end of the two storage frames 501 is fixedly connected to a first connecting pipe 505, both ends of the connecting pipe 4012 are rotatably connected to a rotating cylinder 504, and a second connecting pipe 506 is fixedly connected between the first connecting pipe 505 and the rotating cylinder 504.

[0062] During specific implementation, when the connecting plate 406 descends, it drives the pushing rod 502 fixedly connected at the bottom to descend together, and the pushing rod 502 drives the extrusion plate 503 fixedly connected at the bottom to move in the storage frame 501, and transports the liquid inside the storage frame 501 to the inside of the rotating cylinder 504 through the first connecting tube 505 and the second connecting tube 506. Since the rotating cylinder 504 is connected to the connecting tube 4012 in rotation, the liquid enters the inside of the rotating wheel 401 and is transported to the inside of each placement groove 4011 through the circulation groove 4017, so that the baffle 4014 inside the placement groove 4011 rises, and the ejection block 4015 moves out of the placement groove 4011, thereby improving the contact with the yarn and increasing the contact surface between the clamping frame 402 and the rotating wheel 401 when it rotates.

[0063] A method for guiding filaments of direct-spun FDY fine-denier cationic polyester filaments is also provided, comprising the following steps:

[0064] Step 1: Pass the yarn through the guide plate 101, the fixing cylinder 2, the locking frame 4 and the tensioning frame 3 in sequence, and fix it to the winding device outside the placing frame 5;

[0065] Step 2: When the winding device is winding, the gear plate 201 between the two fixed cylinders 2 rotates, driving the grinding element provided on the outside to remove the lint from the outside of the yarn;

[0066] Step 3: The yarn is guided by the tensioning wheel 301 inside the tensioning frame 3, and the yarn is tensioned and adjusted by the elastic member outside the tensioning wheel 301;

[0067] Step 4: When the yarn breaks, the locking pieces on the two locking frames 4 lock the yarn on the rotating wheel 401 .
