Description

Technical Field

[0002] Extruders are commonly used machines in the cable industry. The main extrusion raw material is plastic granule masterbatch. During operation, the plastic granule masterbatch is fed into the extruder, which has a built-in push screw and heating device. The heating device melts the masterbatch, and the push screw pushes the molten masterbatch to the extrusion head of the extruder. The production principle is to mix and stir the plastic granules, and then extrude them into strip products through the heating technology of the extrusion mechanism. The wire and cable extruder wraps an insulating shell around the cable core, and then the strip products are cooled through a cooling tank.

A discharge chamber is located at the end of the feeding channel, and a discharge port is located in the discharge chamber, which is connected to the extruder body. The stirring device is located in the stirring chamber, and the kneading device is located in the feeding channel.
