AI Technical Summary

Technical Problem

During the melt extrusion stage of raw materials, the existing non-woven fabric spinning device may cause the molten raw materials to solidify due to cooling and adhere to the inner wall of the sleeve or the screw rod, resulting in obstacles in extrusion operations and material blockage, affecting the efficiency of the production process.

Method used

A high-efficiency medical non-woven fiber spinning equipment is designed, and a rotating shaft and agitating assembly are used for sleeves. Through the meshing of the first bevel gear and the second bevel gear, the stirring rod is driven to rotate, stir the molten raw materials to prevent solidification; at the same time, the heating assembly inside the rotating shaft is uniformly heated by a thermal conductive block to prevent the raw materials from being cooled and adhered.

Benefits of technology

It effectively prevents the molten raw materials from solidifying and adhering during the extrusion process, improves spinning efficiency and stability, avoids material blockage, and ensures the smooth progress of the production process.
