Double-screw extruder for cable material production

Abstract

The invention relates to the technical field of double-screw extruders, and discloses a double-screw extruder for cable material production, which comprises a workbench. According to the double-screw extruder for cable material production, through the arrangement of a crushing box, when the double-screw extruder is used, two servo motors are started to rotate in opposite directions, output shafts of the servo motors rotate to drive a movable shaft, a roller and a cutter device to rotate along with the servo motors, at the moment, feeding is conducted through a feeding pipe, plastic particles fall into the crushing box through the feeding pipe, and then the plastic particles are crushed; and through rotary clamping of the cutter device, a cutter cuts up all plastic particles, the cut-up plastic particles naturally fall into a double-screw extruder body below and are shaped through the double-screw extruder body, a cleaning brush cleans the plastic particles adhering to the cutter device on the side face, and at the moment, a limiting ring plays a limiting role, so that the plastic particles are completely cut up through the cutter device, cleanness of the cutter device is guaranteed, the cutter device is prevented from being clamped, use is easy, and operation is more convenient.

Description

technical field [0001] The invention relates to the technical field of twin-screw extruders, in particular to a twin-screw extruder for cable material production. Background technique [0002] Twin-screw extruder is developed on the basis of single-screw extruder. Due to its good feeding performance, mixing and plasticizing performance, exhaust performance and extrusion stability, it has been widely used in extruded products. molding processing. [0003] Most of the common twin-screw extruders currently on the market pour untreated plastic particles directly into the feed pipe during use, and then rotate the screw to extrude the shape, which causes a relatively large pressure on the screw, and may The situation that the machine is stuck will reduce the service life of the machine, so a twin-screw extruder for cable material production is proposed to solve the above-mentioned problems. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at th...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a twin-screw extruder for cable material production, which has the advantages of automatically chopping plastic particles, etc., and solves the problem that most of the common twin-screw extruders in the market are in use. Pour untreated plastic particles directly into the feed pipe, and then rotate the screw to extrude the shape, which will cause a relatively large pressure on the screw, and may cause the machine to be stuck.
