[0002] A spinneret, also known as a spinning plate or spinneret head, is a key component used in the manufacture of chemical fibers. It is usually made of metal and is covered with thousands of tiny holes. These holes are used to guide molten or solution-state polymers through to form fiber filaments. The role of the spinneret in the spinning process is crucial, as it directly affects the quality and output of the fibers.

[0003] After retrieval, the Chinese patent publication number: CN210394604U discloses an automatic cleaning device for the spinneret of a spinning machine. Through the cooperation of a rotating roller, a conveyor plate, a high-pressure water spray pipe, and an engine inside the chassis shell, during the process of conveying the spinneret, the high-pressure water spray pipe is connected to a water pipe to wash the fibers on the spinneret, ensuring that there is no large amount of fiber residue on the spinneret.

[0004] In the above technical solution, the conveyor plate and the high-pressure water spray pipe are used to wash and clean the spinneret. However, the spinneret lacks a positioning function during cleaning, which may cause the spinneret to shift due to the impact of high-pressure flushing. At the same time, the flushing amplitude being in a fixed state will reduce the cleaning effect. Therefore, an automatic cleaning device for a spinneret is proposed to solve the above problems.

[0032] Refer to Figures 1 - 3, an embodiment provided by the present utility model: an automatic cleaning device for a spinneret, including a housing 1, a frame 2 is fixedly connected to the outer wall of the housing 1, a conveyor belt 3 is arranged on the surface of the frame 2, two sets of driving rollers are arranged at both ends of the conveyor belt 3, and one set of driving rollers is driven by a driving motor to operate. The conveyor belt 3 conveys and transports the spinneret. A cleaning structure is arranged inside the housing 1. The cleaning structure includes an electric push rod 4. The output end of the electric push rod 4 is fixedly connected to a clamping plate 5. There are two sets of the electric push rod 4 and the clamping plate 5, and the two sets of the electric push rod 4 and the clamping plate 5 are arranged in a mirror image with the central axis of the housing 1 as the symmetry axis. A drain hole 6 is opened on the inner wall of the housing 1. The inside of the housing 1 is arranged in an inclined shape, and the side far from the conveyor belt 3 inclines downward. A water collecting box 7 is arranged inside the housing 1. The water collecting box 7 is arranged inside the housing 1 and can be drawn out from the inside of the housing 1. A high-pressure water pump 8 is fixedly connected to the top of the housing 1. A delivery pipe 14 is arranged inside the housing 1. A high-pressure spray head 15 is arranged on the surface of the delivery pipe 14. A rotating assembly is arranged on the surface of the housing 1. A supporting assembly is arranged inside the housing 1.

[0033] Referring to Figures 3 - 5 , the rotating assembly includes a collar 9. The inner wall of the upper end of the collar 9 is rotationally connected to the outer wall of the pipe connected to the output end of the high-pressure water pump 8. The outer wall of the collar 9 is rotationally connected to the inner wall of the housing 1. The top of the housing 1 is fixedly connected to a mounting bracket 10. A motor 11 is fixedly connected to the top of the mounting bracket 10. The output end of the motor 11 is fixedly connected to a rotating shaft 12. A transmission belt 13 is connected to the surface of the rotating shaft 12 in a transmission manner. The transmission belt 13 is in transmission connection with the collar 9. The inner wall of the collar 9 is fixedly connected to the outer wall of the delivery pipe 14. The supporting assembly includes an annular groove 16. The annular groove 16 is opened on the inner wall of the housing 1. A slider 17 is slidably connected to the inner wall of the annular groove 16. A support rod 18 is fixedly connected to the bottom of the slider 17. There are two sets of the slider 17 and the support rod 18, and the two sets of the slider 17 and the support rod 18 are arranged symmetrically with the delivery pipe 14 as the symmetry axis. The delivery pipe 14 is arranged in an inverted T shape. The end of the support rod 18 far from the slider 17 is fixedly connected to the outer wall of the delivery pipe 14.

[0034] Referring to Figure 2 , Figures 4 - 5 , a filter screen 19 is arranged inside the water collecting box 7. The input end of the high-pressure water pump 8 is fixedly connected to a three-way pipe 20. External threads 21 are opened on the outer wall of the end of the three-way pipe 20 far from the high-pressure water pump 8. The three-way pipe 20 has three sets of ports. One set is connected to the input end of the high-pressure water pump 8, one set has external threads 21 opened, and the last set is connected to an external pipe to introduce water source. A telescopic pipe 22 is fixedly connected to the inner wall of the water collecting box 7. The telescopic pipe 22 penetrates through the outer wall of the housing 1. A threaded ring 23 is rotationally connected to the outer wall of the telescopic pipe 22. The inner wall of the threaded ring 23 is in threaded connection with the external threads 21.

[0035] Working principle: Place the spinneret plate to be cleaned on the conveyor belt 3 for transportation. After the spinneret plate approaches the inside of the housing 1, two groups of electric push rods 4 are activated to drive two groups of clamping plates 5 to approach the spinneret plate until the spinneret plate is positioned, avoiding the reduction of the cleaning effect caused by the offset of the spinneret plate during high-pressure flushing. Since the inside of the housing 1 is inclined downward, there is a certain gap between the spinneret plate and the drain hole 6. At this time, the three-way pipe 20 introduces the external water source, and the high-pressure water pump 8 transmits the water source into the high-pressure nozzle 15 to clean the surface of the spinneret plate. Then, turn on the motor 11, and the motor 11 drives the rotating shaft 12 to rotate slowly. When the conveying pipe 14 rotates, two groups of support rods 18 will drive the slider 17 to slide inside the annular groove 16 to ensure the stability of the rotation of multiple high-pressure nozzles 15. The rotating belt 13 makes the collar 9 rotate to expand the water spraying and cleaning area of multiple high-pressure nozzles 15, avoiding cleaning dead corners during the cleaning of the spinneret plate. The cleaned sewage will flow through the drain hole 6 into the inside of the water collecting box 7 and be filtered through the filter screen 19. Then, pull the telescopic pipe 22 so that the threaded ring 23 is inserted into the three-way pipe 20 until the threaded ring 23 is connected to the external thread 21, and the filtered water source is reused, making it convenient for the water source with added cleaning agent to be introduced by the high-pressure water pump 8 to clean the spinneret plate for the second time, improving the cleaning efficiency.
