Description

Technical Field

[0001] The utility model relates to the technical field of cable processing, in particular to an extruder with a crushing function for processing electric wires and cables. Background Art

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. With the rapid growth of my country's economy and continuous investment in infrastructure, the use of cables is increasing, and the task of cable processing is becoming more and more arduous. The cable processing process is inseparable from the plastic extruder. The currently commonly used cable processing plastic extruder mainly puts plastic raw materials into the feed hopper. The pressure and shear force generated by the rotation of the screw can make the material fully plasticized and evenly mixed, and then squeezed to the head, and extruded into shape by the head.

[0003] Common cable extruders are generally composed of an extrusion mechanism and a feeding mechanism. In order to improve the quality of extrusion, a crushing roller is installed inside the feeding mechanism to extrude and crush the raw materials for the production of wires and cables so that they can be better extruded.

[0004] However, in this method, since the wire and cable raw materials are crushed and discharged centrally through the discharge hopper, uneven crushing is prone to occur when the crushing roller is extruded, and the discharge port is easily blocked, resulting in uneven crushing of the raw materials, which in turn affects the quality of the extrusion process and cannot meet the working requirements of cable processing. Therefore, an extruder for wire and cable processing with a crushing function is proposed. Utility Model Content
