[0002] The extrusion device used in the production of communication cables, commonly referred to as a cable extruder or wire and cable extruder, is a crucial piece of equipment specifically designed for the production of wires and cables. The cable extruder's operating principle is that a specially shaped screw rotates within a heated barrel, forcing plastic fed from a hopper forward, causing it to plasticize (i.e., melt) evenly. The plastic is then extruded through a die head and various molds to form continuous layers of various desired shapes, which are then wrapped around the wire core and cable.

[0003] Before the wire core enters the extruder head, the existing extrusion device generally uses drag force to extract the wire core from the wire core roll and move it to the head for plasticization. However, during this process, the wire core will be contaminated by fine dust and other substances in the air, so that the inside of the extruded cable will be filled with dust, etc., affecting the electrical conductivity and insulation performance of the cable. After a long time, it may even cause physical and chemical corrosion and damage to the cable. In response to the above situation, the utility model provides an extrusion device for communication cable production to solve the above problems. Utility Model Content
