Description

Parallel circulating flow type PE pipe extruder

Technical Field

The utility model belongs to the technical field of extruders, and particularly relates to a parallel circulating flow type PE pipe extruder.

Background

Extruders are one of the class of plastic machines, originating from the 18 th century. The extruder can divide the machine head into a right-angle machine head, an oblique-angle machine head and the like according to the material flow direction of the machine head and the included angle of the central line of the screw. The screw extruder is capable of fully plasticizing and uniformly mixing materials by means of pressure and shearing force generated by rotation of a screw, and the plastic extruder can be basically classified into a double-screw extruder, a single-screw extruder, a rare multi-screw extruder and a non-screw extruder through the molding of a neck mold, wherein a PE pipe can also be produced by the extruder.

In the prior art, most extruders can only extrude PE pipes of one size, and if PE pipes of different sizes need to be produced, another extruder needs to be used for production, so that the practicability of one extruder is very low.

SUMMERY OF THE UTILITY MODEL
