The top of the housing 1 is fixedly provided with a cylinder 21, the output end of the cylinder 21 is fixedly connected to the top of the filter housing 6, a sealing assembly for blocking the connecting hole 401 is arranged in the filter housing 6, both sides of the filter housing 6 are provided with filter screens 7, one side of the housing 1 is connected with an injection port 3, both sides of the top of the housing 1 are connected with an injection pipeline 22 and a recovery pipeline 23, the injection pipeline 22 is arranged above the injection port 3, and two injection ports 220 are arranged on the injection pipeline 22. 1. Two recovery ports 2301 are arranged on the recovery pipeline 23, and two injection ports 2201 are arranged opposite to the two recovery ports 2301 respectively. When cleaning the filter screen 7, the sliding plate 4 is moved to the top of the injection port 3, and the connecting hole 401 is blocked by the sealing component, and the polymer solution is injected through the injection pipeline 22, so that the polymer solution washes the surface of the filter screen 7 and is recovered through the recovery pipeline 23. When cleaning, the polymer solution is sprayed out through the two injection ports 2201 on the recovery pipeline 23, and two sections of liquid flow are formed between the two injection ports 2201 and the two recovery ports 2301. The liquid flow passes through the two sides of the two filter screens 7, so as to wash away the large particles of impurities attached to the filter screen 7, and the filter screen 7 can be cleaned automatically and timely, thereby improving the service life of the device. When cleaning, the filter screen 7 does not need to be disassembled, and there is no need to shut down for a long time. It is suitable for long-term continuous production, effectively improving processing efficiency, and directly using the polymer solution for cleaning will not cause the filter screen 7 to be contaminated, so as to ensure the purity of the solution in the shell 1.

[0029] In this embodiment, preferably, a baffle ring 24 is fixedly installed inside the shell 1, and a sealing disk 25 is arranged above the baffle ring 24. The output end of the cylinder 21 passes through the sealing disk 25, and the output end of the cylinder 21 slides with the sealing disk 25. The top of the sealing disk 25 is fixedly connected with a first spring 26, and the top of the first spring 26 is fixedly connected to the top wall of the shell 1. When the sliding disk 4 is located below the baffle ring 24, under the elastic action of the first spring 26, the bottom wall of the sealing disk 25 fits with the top wall of the baffle ring 24, thereby sealing the cleaning space above the baffle ring 24.

[0030] In this embodiment, preferably, the sealing assembly includes a blocking plate 27, a sliding column 28 and a second spring 29. The blocking plate 27 is arranged just above the connecting hole 401. The blocking plate 27 is used to block the connecting hole 401.

[0031] When in use, the polymer solution is injected into the housing 1 through the injection port 3. The polymer solution enters the filter cover 6 after being filtered by the filter screen 7, and then flows downward through the connecting hole 401 on the slide plate 4, so as to be ejected through the spinneret hole 201 on the spinneret 2 to eject molten polymer fibers, which are formed into fibers after being stretched, cooled and molded. When the spinneret device is used for a long time, some large particles of impurities are attached to the filter screen 7. At this time, the slide plate 4 is driven upward by the cylinder 21. After the slide plate 4 moves upward, the blocking plate 25 is pushed upward through the filter cover 6, so that the filter cover 6 moves upward. The filter 24 moves to the cleaning space above the retaining ring 24. At the same time, under the squeezing action of the sealing plate 25, the sliding column 28 moves downward relative to the filter cover 6, so that the sealing plate 27 blocks the connecting hole 401, and then the polymer solution is injected into the injection pipeline 22. The polymer solution is sprayed out through the two injection ports 2201 on the recovery pipeline 23, and two sections of liquid flow are formed between the two injection ports 2201 and the two recovery ports 2301. The liquid flow passes through both sides of the two filter screens 7, thereby washing away the large particles of impurities attached to the filter screens 7, and finally discharged through the recovery pipeline 23 for recovery.

[0032] After the spinning device is used for a long time, the molten polymer fiber ejected through the spinneret hole 201 may adhere to the edge of the outlet of the spinneret hole 201, thereby affecting the subsequent spinning effect.

[0035] The driving assembly includes a nut 17, a screw rod 14, a push plate 18 and a fourth spring 20. The nut 17 is fixedly installed on the top of the rotating cylinder 15. The screw rod 14 passes through the nut 17, and the screw rod 14 is threadedly connected to the nut 17. The screw rod 14 is a ball screw 14. The push plate 18 is fixedly installed on the top of the screw rod 14. The fourth spring 20 is sleeved on the screw rod 14, and the top of the fourth spring 20 is fixedly connected to the push plate 18.

[0037] When the spinneret hole 201 on the spinneret 2 and the bottom wall of the spinneret 2 need to be cleaned, the slide plate 4 is driven downward by the cylinder 21, thereby driving the cleaning column 5 to move downward, so that the cleaning column 5 is inserted into the spinneret hole 201, thereby cleaning the spinneret hole 201, and after the slide plate 4 moves downward until the push plate 402 contacts the push plate 18, the slide plate 4 can move downward, and when the slide plate 4 moves downward, it pushes the screw rod 14 to move downward, and when the screw rod 14 moves downward, it drives the nut 17 to rotate, thereby driving the rotating cylinder 15 to rotate, and when the rotating cylinder 15 rotates, it drives the installation box 8 to rotate, and when the screw rod 14 moves downward, it drives the slider 16 to move downward , causing the top end of the traction rope 13 to move downward, and then the slide 10 to move outward under the elastic action of the third spring 12, so that the scraper 11 extends out from the slide groove 801, and the installation box 8 can drive the scraper 11 to rotate when it rotates. When the scraper 11 extends outward, it can scrape off the material attached to the outlet of the spinneret hole 201 on the bottom wall of the spinneret 2. When the slide plate 4 moves upward, under the elastic action of the fourth spring 20, the push plate 18 and the screw rod 14 can be reset, and the slide 10 is pulled back by the traction rope 13, so that the scraper 11 shrinks into the slide groove 801 to avoid the slide plate blocking the outlet of the spinneret hole 201 and affecting the spinneret.

[0039] Working principle: The polymer solution is injected into the housing 1 through the injection port 3. The polymer solution enters the filter cover 6 after being filtered by the filter screen 7, and then flows downward through the connecting hole 401 on the slide plate 4, thereby being ejected through the spinneret hole 201 on the spinneret 2 to eject molten polymer fibers, which are formed into fibers after being stretched, cooled and formed. When the spinneret device is used for a long time, some large particles of impurities are attached to the filter screen 7. At this time, the slide plate 4 is driven upward by the cylinder 21. After the slide plate 4 moves upward, the blocking plate 25 is pushed upward by the filter cover 6, so that the filter cover 6 moves To the cleaning space above the retaining ring 24, at the same time, under the squeezing action of the blocking plate 25, the sliding column 28 moves downward relative to the filter cover 6, so that the blocking plate 27 blocks the connecting hole 401, and then the polymer solution is injected into the injection pipeline 22, and the polymer solution is sprayed out through the two injection ports 2201 on the recovery pipeline 23, and two sections of liquid flow are formed between the two injection ports 2201 and the two recovery ports 2301.
