AI Technical Summary

Technical Problem

Existing extrusion equipment for cable production lacks preliminary preheating of plastic granules, resulting in excessively long heating times and limiting the overall efficiency of the extruder.

Method used

A water supply heating mechanism is used to continuously heat the plastic granules in the feed hopper. Combined with the transmission mechanism driving the screw and the installation tube to agitate, the plastic granules are heated evenly. A cooling water machine provides cold water of different temperatures to gradually cool the cable surface and prevent overcooling.

Benefits of technology

This improves the heating efficiency of plastic granules, reduces subsequent heating time, enhances the extrusion efficiency and quality of the cable surface insulation layer, ensures consistent cooling effect, and meets the requirements of high-quality cables.
