AI Technical Summary

Technical Problem

The existing screw extruders cannot stir and mix when loading plastic masterbatches, resulting in uneven composition of the extruded plastic semi-finished products and low practicality; at the same time, the plastic masterbatches are prone to block the filter screen, resulting in the inability to load and low working efficiency.

Method used

A molding extrusion device including a conveying mechanism and a filtering mechanism is designed. The conveying mechanism realizes the stirring, mixing and conveying of plastic masterbatches through the conveying motor, mounting shaft, stirring sheet and spiral blades. The filtering mechanism passes through a fan and a filter plate to separate the plastic masterbatch from the dust to prevent clogging.

Benefits of technology

Through stirring and mixing, the uniformity of the components of the semi-finished plastic products is ensured and practicality is improved. Through filtration and dust collection, the plastic masterbatch is prevented from clogging the filter net, and the working efficiency is improved.

Abstract

The utility model discloses a molding extrusion device for a ppr pipe production process, relates to the technical field of screw extruders, and aims to solve the problems that extruded plastic semi-finished products are non-uniform in component and low in practicability due to the fact that plastic master batches cannot be stirred and mixed, and the plastic master batches can block a filter screen, so that feeding cannot be performed, and the working efficiency is low in the background technology. According to the scheme, the screw extruder comprises a screw extruder body, a mounting cover is arranged on the outer wall of the top end of a feeding hopper of the screw extruder body, a mounting mechanism is arranged on a base of the screw extruder body and comprises a mounting plate, a conveying mechanism is arranged below the top of the mounting plate, and the conveying mechanism comprises a conveying motor. According to the plastic master batch stirring and mixing device, plastic master batches can be stirred and mixed, uneven distribution of components of extruded plastic products is prevented, the practicability is improved, the plastic master batches and dust can be separated and collected, the plastic master batches are prevented from blocking the filter plate, and the working efficiency is improved.
