AI Technical Summary

Technical Problem

Existing ABA composite polyolefin fiber drawing production equipment is cumbersome to disassemble and assemble when changing materials and specifications, resulting in low production efficiency. Furthermore, molten materials are prone to stagnation in the flow channels, leading to thermal degradation and carbonization, which affects product quality.

Method used

The modular, quick-release layered composite flow channel module and the V-shaped guide slope combined with the reciprocating scraper design enable rapid material and specification changes. PLC control allows for precise scraping of accumulated material, avoiding material stagnation in dead corners of the flow channel.

Benefits of technology

This technology enables rapid material and specification changes while avoiding material accumulation in the flow channel, thus improving product quality stability and production efficiency, and extending the continuous production cycle.
