[0002] The extruder is an important plastic machine. The production and manufacturing of most plastic products can be achieved by extrusion molding. In the prior art, the cable production extruder will cause uneven extrusion of cable raw materials during the cable manufacturing process. In addition, the cable raw materials cool down quickly and the mixing equipment is not convenient for loading and unloading, resulting in insufficient internal cleaning, which affects the next use.

[0003] For example, the authorized patent document with application number CN202321084653.3 discloses an extruder for cable production, which includes a mounting base, an extrusion device and a control device. The mounting base is composed of a support rod, an anti-slip disk, a mounting plate, a storage tank and a multi-functional heat dissipation door. A control device is provided on the front of the mounting base, which is composed of a control panel, an LED display screen and control buttons. An extrusion device is provided on the upper side of the mounting base, which is composed of an extrusion kettle, a drive motor, a motor bracket, a transmission shaft, a conveying arc sheet, a heating tube, a feed port and a partition plate. Since a heating tube is provided inside the extrusion device of the utility model, the heating tube can heat the cable raw material during the extrusion process, which can effectively prevent the cable raw material from condensing in the extrusion kettle. In addition, the utility model performs texturing treatment on the conveying arc sheet of the extrusion device, which can greatly increase the contact area between the conveying arc sheet and the cable raw material during the extrusion process, thereby achieving an excellent transmission effect.
