AI Technical Summary

Technical Problem

In existing co-extrusion multilayer casting feeders, uneven melting of solid raw materials leads to inconsistent density of the mixed colloid, affecting product quality stability.

Method used

It adopts a liquefaction feeding mechanism and a negative pressure conveying mechanism. The heating shell and electric heating wire are used for preheating and melting. Combined with the conveying screw and the dispersing screw, the raw materials are mixed evenly. The negative pressure conveying is used to stabilize the conveying of raw materials and prevent cooling solidification and leakage.

Benefits of technology

This process achieves uniform density of the mixed colloids, ensuring the stability of subsequent processes and product quality, improving production efficiency, and preventing cooling solidification and leakage during raw material transportation.
