[0002] Wire and cable is a device for transmitting electric energy or signals, usually made of several or several groups of wires twisted together; the wire and cable are provided with armor on the outside to improve the overall strength and safety, and the insulation layer is part of the cable armor. During the processing, the core wire of the wire and cable needs to pass through the extrusion hole on the extruder. While the core wire of the wire and cable passes through, the molten plastic extruded by the extruder adheres to the outer surface of the core wire in the form of glue to form an insulation layer. During the continuous stretching process of the core wire of the wire and cable, the core wire can be continuously coated;

[0003] In the prior art, a patent with authorization announcement number CN 212516708 U discloses an automatic insulating layer covering device for producing wires and cables. When scraping glue, the portion of the wire and cable core that has been injected with glue passes through the first through hole set on the mounting plate and the driven gear under the traction of the receiving roller, and the motor rotates to drive the driving gear and the driven gear to rotate. The scraper blade set on the driven gear abuts against the injected insulating layer of the wire and cable.

However, the position of the scraper blade cannot be adjusted, and it cannot adapt to the manufacture of cables of different diameters. It has poor adaptability and cannot meet processing requirements. Utility Model Content
