Description

Technical Field

[0001] This utility model belongs to the field of spinneret hole opening technology, and specifically relates to a mold for processing spinneret guide holes. Background Technology

[0002] A spinneret, also known as a spinning cap, is used to transform viscous polymer melts or solutions into fine streams with specific cross-sectional shapes through micropores. These streams are then solidified by a solidification medium such as air or a coagulation bath to form filaments. Depending on the type and specifications of the fibers, spinnerets come in different sizes, shapes, orifice types, and materials. Spinnerets operate at high temperatures and pressures, requiring pressure resistance, corrosion resistance, and sufficient mechanical strength. Spinneret orifices typically consist of guide holes and capillary pores. When the melt flows from a large space into very small micropores, the flow velocity increases dramatically. To control the shear rate of the melt flow and obtain a larger pressure differential, conical and hyperboloid guide holes are preferred.

[0003] Currently, Chinese utility model patent CN216656433U discloses a micro-hole opening device for spinnerets. Existing spinnerets are not easy to rotate or flip after being fixed during processing, which makes it impossible to achieve precise alignment and uniform distribution of holes on the spinneret during processing. Furthermore, it is impossible to process multiple holes during the guidance and control process, which affects processing efficiency. Utility Model Content
