[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information and realize electromagnetic energy conversion. Wires and cables in a broad sense are also referred to as cables. Cables in a narrow sense refer to insulated cables. During the production and processing of cables, they need to be wrapped with insulating sheaths. Most insulating sheaths are made of polyvinyl chloride insulation. When processing the insulating sheaths, the polyvinyl chloride insulation needs to be heated at high temperature and then extruded and wrapped on the outer wall of the cable. Therefore, this extrusion feeding device plays a very important role in cable processing.

[0003] However, there are many steps to be performed in the cable processing process, and extrusion feeding of insulating materials is only one of them. After the material is extruded, it needs to be docked with the wrapping equipment, and the extruded material is transferred to the cable wrapping equipment for cable wrapping. In this process, the feeding device needs to be docked, but the height of the feeding area at the upper end of the existing feeding device is basically fixed and cannot be adjusted. When docking with cable processing machines of different models, it may be impossible to dock due to the height difference, and the height of the feeding device or other equipment must be increased externally for docking. This method affects the stability of the overall use of the device, and thus affects the processing quality of the cable. Utility Model Content
