The function of the spinneret is to transform the viscous polymer melt or solution into a fine flow with a specific cross-section through the micropores, and form a filament through the solidification medium. That is, the spinneret is installed on the extrusion device, and the raw material enters from the feed hole, passes through the spinneret channel, and then forms a filament through the discharge hole and is ejected; the existing spinneret is such as the annular spinneret with application number 2015207293997 The plate comprises a spinneret, and a central positioning through groove is provided at the center of the spinneret; the spinneret comprises a main material ring, a positioning inner ring and a positioning outer ring; both inner and outer end surfaces of the main material ring are upwardly protruding with material ring flanges, the positioning outer ring is integrally connected to the material ring flange on the outer side of the main material ring, and the positioning inner ring is integrally connected to the material ring flange on the inner side of the main material ring; a collecting groove is formed between the main material ring and the material ring flanges on both sides thereof, and the upper end surface of the main material ring is a feed end surface, and the feed end surface The end face is at the bottom of the feed trough, and a plurality of feed ports are arranged on the feed end face, and the feed ports are regularly arranged circumferentially along the center of the spinneret; the lower end face of the main material ring is the discharge end face, and a plurality of discharge ports are arranged on the discharge end face, and the number of the discharge ports is twice that of the feed ports, and each feed port corresponds to two discharge ports, and the corresponding feed ports and discharge ports are connected through a spinneret channel that runs through the main material ring; the spinneret channel includes a feed slot at the upper end, and two discharge slots connected to the lower end of the feed slot, and the circumferential tangent section of the feed slot is a trapezoidal shape with a large opening at the upper end and a small opening at the lower end, and the radial center line of the feed slot corresponds to the center of the ring body of the spinneret; the two discharge slots are symmetrical to each other along the radial center line of the feed slot; when used, the spinneret is installed at the extrusion port of the extrusion device, and the viscous flow raw material can be evenly distributed along the feed trough, and the pressure is gradually increased, and the raw material will be squeezed out from the discharge port to form hair under the spinneret to complete the spinning work.

[0003] The spinneret collecting trough can prevent material leakage. However, during the production of the spinneret, some impurities or raw materials may often form material accumulation inside the collecting trough. The accumulated material will age after a certain period of time, and the accumulated material will be carried out with the raw materials from time to time, affecting the product quality. If the aged accumulated material is large, it will cause hole blockage, and the entire spinneret needs to be replaced and cleaned regularly, but cleaning the spinneret is time-consuming and labor-intensive. In order to solve the above problems, there is also a filter net directly placed in the collecting trough to filter the raw materials and reduce the possibility of material blockage. If the filter net is blocked, the cost of cleaning or replacing the filter net is also low. However, the raw materials are easy to flow into the collecting trough from the gap between the outer wall of the filter net and the inner wall of the positioning inner ring, and there is also a problem of hole blockage caused by the above-mentioned accumulation of materials.
