Plastic twin-screw extruder for injection molding production of plastic products

Abstract

The invention relates to the technical field of plastic extrusion, in particular to a plastic twin-screw extruder for injection molding production of plastic products. The plastic twin-screw extruder comprises an equipment main body and a material distribution switching component, wherein the equipment main body comprises a base, the top of the base is provided with a machine body, one side of the top of the machine body is provided with a feeding port, one side of the machine body is provided with a control panel, a material blowing box is arranged in the feeding port, and material distributing boxes are arranged at the two sides of the top of the material blowing box; and the material distribution switching component comprises a filter screen, a shaft rod is movably connected to the center position of the top of the filter screen through a bearing, and a switching rotary drum is installed at the outer side of the shaft rod. According to the plastic twin-screw extruder, the problems that when various plastic particles are fed, plastic raw materials are often unevenly distributed, and the plastic particle raw materials are prone to being extruded at the feeding port, so that tension among the plastic particles is too large, and the feeding port is stuck are effectively solved.

Description

technical field [0001] The invention relates to the technical field of plastic extrusion, in particular to a plastic twin-screw extruder for injection molding production of plastic products. Background technique [0002] When processing and producing plastic products, most of them need to use plastic extruders to process and produce plastic products, while twin-screw extruders are developed on the basis of single-screw extruders. The characteristics of refining plasticization performance, exhaust performance and extrusion stability are widely used; [0003] For example, the patent No. is a plastic extruder disclosed in CN110253817B. This invention includes a frame, the raw material processing mechanism includes a heating chamber arranged in the frame, and a first motor is fixedly installed on the top end surface of the frame. The lower output shaft of the first motor is fixedly connected to the motor shaft, and the motor shaft runs through the heating chamber and rotates be...
