Extrusion tool for plastic tubular product

Abstract

The invention discloses an extrusion tool for a plastic tubular product, and relates to the technical field of extrusion of plastic products. The extrusion tool disclosed by the invention comprises a supporting device, a feeding device, a stirring device, a heating device, an extruding device, a cutting device and a cooling device; the supporting device comprises a bearing plate and a supporting column; the upper surface of the bearing plate is connected with the lower surface of the supporting column; the feeding device comprises a feeding hopper; the stirring device comprises a transmission element and a stirring rod; the heating device comprises a shell; the lower surface of the shell and the upper surface of the bearing plate are welded together; the extruding device comprises a speed adjusting motor; the lower surface of the speed adjusting motor is connected with the upper surface of the supporting column; the cutting device comprises connecting plates; the cooling device comprises a cooling bin; and the outer surface of the cooling bin is connected with the inner surfaces of a plurality of connecting plates. According to the extrusion tool provided by the invention, under the rotation of an extrusion roller, an extruded plastic pipe is pushed out of an extrusion barrel through protruding threads on the surface, the plastic pipe is conveniently separated from the extrusion barrel, and the pushing speed of the extrusion roller can be adjusted through the speed adjusting motor, so convenience is provided for formation of plastic powder.

Description

technical field [0001] The invention belongs to the technical field of extrusion of plastic products, in particular to an extrusion tool for plastic tubular products. Background technique [0002] The plastic extruder can be matched with various plastic molding auxiliary machines such as pipes to form a variety of plastic extrusion molding production lines to produce various plastic products. Therefore, plastic extrusion molding machinery is a must-have in the plastic processing industry no matter now or in the future. One of the widely used models. [0003] When the existing extrusion device for plastic tubular products feeds plastic powder raw materials, the moisture in the air contacts the plastic powder, which causes agglomeration. After entering the interior of the feeding device, it is easy to cause blockage to the feeding hopper. After the product is extruded, it is easily bent and deformed due to the influence of gravity. It is not suitable for a small number of pla...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide an extrusion tool for plastic tubular products, which solves the problem of agglomeration caused by the contact of moisture in the air with the plastic powder when the existing extrusion device for plastic tubular products feeds plastic powder raw materials , after entering the feeding device, it is easy to block the feeding hopper. After the plastic tubular product is extruded, it is easily bent and deformed under the influence of gravity. It is not suitable for a small number of special plastic products. The problem of fragmentation during use
