AI Technical Summary

Technical Problem

Existing polytetrafluoroethylene composite material production equipment cannot effectively shape materials of different shapes during the extrusion process, resulting in low production efficiency and requiring many subsequent processing steps.

Method used

An extruder with a chute and a moving plate was designed. The die slides within the chute and is combined with a motor-driven rotating shaft and gear system to extrude materials of different shapes. The material is uniformly heated by a heating plate to ensure uniform flow of the material in the die.

Benefits of technology

It enables direct extrusion of materials of different shapes, reduces subsequent processing steps, improves production efficiency, and ensures the dimensional accuracy and appearance quality of the products.

Abstract

The utility model discloses an extruder for polytetrafluoroethylene-based composite material production, and relates to the technical field of composite material production, the extruder comprises a shell, an extrusion mechanism is arranged in the shell, a heating mechanism is arranged in the shell, the extrusion mechanism comprises a groove, the inner wall of the groove is fixedly connected with a sliding chute, and the sliding chute is connected with the heating mechanism. Through the arrangement of the moving plate, the first bolt can be screwed out, then the moving plate slides in the sliding groove, so that other molds are aligned with the material extruding barrel, then the first bolt is screwed in the moving plate to fix the position of the moving plate, then the motor is started, the motor enables the rotating shaft to rotate at the moment, and the rotating shaft is rotated. And then the rotating shaft drives the first gear to rotate, and through the moving plate capable of sliding in the sliding groove, the effects that materials of different shapes can be extruded according to specific requirements, extruded products of different shapes can directly meet the final application requirements, the later machining steps are reduced or avoided, and therefore the production efficiency is improved are achieved.
