Novel multi-layer extrusion forming device

Abstract

The invention discloses a novel multi-layer plastic extrusion device which belongs to the technical field of plastic extrusion, and solves the problems that weld marks are generated in the conventional plastic extrusion forming and the product quality is low in the market. The device comprises an engine base, wherein a bracket is arranged on the engine base; a motor box is arranged on the bracket; a conical sleeve is connected to the front side of the motor box. The device is characterized in that the conical sleeve comprises three layers; the middle layer is a rotating conical sleeve; an inner fixing conical sleeve and an outer fixing conical sleeve are respectively arranged on the inner layer and the outer layer of the rotating conical sleeve; spiral material conveying channels are respectively formed between the inner surface of the rotating conical sleeve and the outer surface of the inner fixing conical sleeve as well as between the outer surface of the rotating conical sleeve and the inner surface of the outer fixing conical sleeve. Weld marks on a product produced by using the device are effectively eliminated, the product quality is improved, and in addition, the quality of the product is further improved as filtering nets are arranged in the feeding ports of the feeding channels, so that the working efficiency is indirectly improved.

Description

technical field [0001] The invention belongs to the technical field of extrusion molding, and relates to a multi-layer plastic extrusion device. Background technique [0002] As we all know, the head of the ordinary single-layer extrusion molding machine currently used in the market is composed of an outer sleeve, a screw, a diverter bracket, etc., and can only perform single-layer extrusion molding of plastics. Two sets of equipment work at the same time. Due to the structure of the head diverter bracket, the welding marks of the product cannot be eliminated, and the degradation of the material due to long heating time affects the work efficiency, energy consumption and product quality. In addition, the existing extruder There are too many impurities in the produced plastic products, which will affect the quality and appearance of the products. Contents of the invention [0003] In view of the deficiencies in the background technology, the object of the present invention...
