[0002] ‌Wind power cables are cables specially designed for wind power generation systems, mainly used to connect various components of wind turbines to ensure the transmission of electrical energy and the normal operation of the system. Wind power cables usually consist of conductors, insulation layers, and sheaths. The conductor materials are commonly copper and aluminum. The insulation layer protects the conductor from the environment, and the sheath protects the wire from mechanical damage and the external environment.

[0003] ‌The outer tube of the wind power cable plays a protective role for the cable itself. When processing the outer tube, an extrusion molding machine is required.

[0004] For example, the Chinese utility model patent with the application number 202020166209.6 discloses a flame-retardant and corrosion-resistant cable outer tube extrusion molding device. Through the setting of multiple adjustment mechanisms, the pressure of the material increases during the extrusion process, so that the material can be fully melted, preventing blockage during the production process, making the product production stable, and greatly improving the production efficiency. However, there are still certain defects in its device;

[0005] When transporting the outer tube raw material, it is impossible to filter out fine impurities in the raw material, resulting in the possibility of more impurities mixed in the raw material. At the same time, it is impossible to preheat the raw material, thus reducing the processing quality and processing efficiency of the cable outer tube.

[0006] Therefore, we propose an outer tube extrusion molding machine for wind power cable production to solve the problems mentioned above. Content of the Utility Model
