Description

Technical Field

[0001] The utility model relates to the technical field of circular spinnerets, in particular to a circular spinneret. Background Art

[0002] The spinneret, also known as the spinning cap, transforms the viscous polymer melt or solution into a thin stream with a specific cross-section through micropores. The stream is then solidified in a coagulation medium such as air or a coagulation bath to form filaments.

[0003] The circular spinneret in the prior art is mostly an integrally formed structure, and has a plurality of spinneret holes. However, during long-term use, the inside of the spinneret holes is easily clogged by the solidification of the solution, which requires the spinneret holes to be dredged and cleaned. The prior art generally adopts ultrasonic cleaning, which uses the vibration of ultrasonic waves to remove dirt from the spinneret and the spinneret holes. However, since the existing spinneret is integrally formed and has a relatively thick thickness, it takes a long time to clean the inside of the spinneret holes during ultrasonic cleaning, and the efficiency of dredging and cleaning the spinneret holes is low. Utility Model Content

[0004] The purpose of the utility model is to provide a circular spinneret to solve the problem that the spinneret of the prior art is integrally formed and has a relatively thick thickness, which leads to a long cleaning time for the inside of the spinneret hole during ultrasonic cleaning and low cleaning efficiency of the spinneret hole.

[0006] As a preferred technical solution, the connecting member includes a plurality of first bolts, a plurality of first mounting holes are opened in the middle of the first circular plate body, a plurality of first through-holes are opened in the middle of the second circular plate body, and a plurality of first thread grooves are opened at the top of the middle part of the third circular plate body. The centers of the first mounting hole, the first through-hole and the first thread groove are aligned, and one end of the first bolt passes through the first mounting hole and the first through-hole in sequence and is threadedly connected to the inside of the first thread groove.

[0007] As a preferred technical solution, it also includes a second bolt, a plurality of second mounting holes are opened at the edge of the first circular plate body, a plurality of second through-holes are opened at the edge of the second circular plate body, a plurality of second thread grooves are opened at the top of the edge of the third circular plate body, the centers of the second mounting hole, the second through-hole and the second thread groove are aligned, and one end of the second bolt passes through the second mounting hole and the second through-hole in sequence and is threadedly connected to the inside of the first thread groove.

[0008] As a preferred technical solution, the limiting member includes a plurality of positioning blocks fixedly installed on the top and bottom edges of the second circular plate body, and the bottom of the first circular plate body and the top of the third circular plate body are respectively provided with positioning grooves equal to the number of the positioning blocks, and the positioning blocks are embedded and clamped inside the positioning grooves.

[0009] As a preferred technical solution, the first bolt and the second bolt are both hexagon socket bolts, and the first bolt and the second bolt are concealedly installed inside the first mounting hole and the second mounting hole, respectively.

[0010] As a preferred technical solution, the spinnerets on the first circular plate, the second circular plate and the third circular plate are all aligned vertically.

[0011] The utility model has at least the following beneficial effects:

When cleaning the spinneret holes on the circular spinneret, the first bolt located in the middle of the first circular plate body is first removed, and then the second bolt located at the edge of the first circular plate body is removed. Finally, the positioning blocks on the top and bottom of the second circular plate body are separated from the positioning grooves on the first circular plate body and the second circular plate body respectively, so that the disassembly of the first circular plate body, the second circular plate body and the third circular plate body can be completed. By reducing the cleaning length of the spinneret holes, the effect of ultrasonic cleaning can be increased, and the efficiency of clearing blockages in the spinneret holes can be improved.
