Technical Field

[0001] The utility model relates to an annular spinneret and belongs to the technical field of spinnerets. Background Art

[0002] The spinneret is also called the spinning cap. The function of the spinneret is to transform the viscous polymer melt or solution into a thin flow with a specific cross-section through micropores, and solidify it into filaments through a coagulation medium such as air or a coagulation bath.

[0003] However, the existing annular spinneret is not convenient for workers to disassemble and replace. Usually, a mounting hole is opened on the outer ring of the spinneret, and workers install and fix it by fastening screws. When it needs to be disassembled for maintenance, it is very cumbersome, and all the fastening screws need to be removed one by one, which causes inconvenience in the disassembly process. At the same time, repeated removal of screws may cause thread slippage, causing the spinneret to shake, affecting normal use.

[0004] For this purpose, an annular spinneret is proposed. Utility Model Content
