Description

Technical Field

[0003] The existing wire arrangement mechanism of the bio-based fiber drawing machine blows air to cool the fiber drawing while the wire arrangement shaft winds the wire. However, when the fiber drawing is wound by the wire arrangement mechanism of the existing bio-based fiber drawing machine, the fiber drawing is easily entangled and accumulated in one place, which affects the cooling effect and causes thermal condensation of the fiber drawing during winding. In order to prevent liquid leakage, most of the existing methods use air cooling to cool the sleeve. Although it can prevent liquid leakage, the heat exchange efficiency is poor and it cannot cool down quickly. Summary of the invention
