Description

Technical Field

[0001] This utility model relates to the field of cable insulation layer production technology, specifically to a rapid extrusion machine for wire and cable insulation layers. Background Technology

[0002] The insulation layer of wires and cables can effectively prevent current from flowing from the conductor to the external environment, reduce power loss, improve power utilization, and prevent current leakage from causing harm to surrounding equipment and personnel. At the same time, the insulation layer can isolate the potential difference between conductors, preventing contact or crossing between conductors, which could cause a short circuit.

[0003] In the production process of insulation layer, an extruder is required to melt and continuously extrude raw materials such as plastic granules through the rotation of the screw and the heating of the barrel to form a uniform insulation layer that covers the conductor or core of the wire and cable, thereby realizing the insulation function of the wire and cable.

[0004] After prolonged use, it was found that traditional extruders, when faced with large-particle insulation materials, would block the screen inside the extruder, causing material blockage and accumulation, affecting the cable insulation production process, and making it inconvenient for the extruder to process.

[0005] Therefore, this utility model provides a rapid extrusion machine for wire and cable insulation layers. Utility Model Content
