[0002] A cable is usually a rope-like electrical energy or signal transmission device composed of several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and often twisted around a center wire. The entire outside is covered with a highly insulating covering. The cable has the characteristics of being powered inside and insulated outside.

[0003] Coating is a process method that adds different materials to the outside of the conductor by using continuous coating machines, continuous extruders, etc. according to the different performance requirements of wires and cables. The coating process content is diverse, and the coating process of different materials is different. For example, rubber, lead, aluminum, plastic and other materials mostly use extrusion process; polyester film, aluminum-plastic composite film and other strip materials mostly use longitudinal wrapping process; mica tape, non-woven fabric, alkali-free glass and other fiber materials mostly use winding process; asphalt, insulating paint and other materials mostly use dipping process.

[0004] Based on the prior art, when using mica tape and other materials to coat the cable, a coating device is used to coat the cable. However, the coating device in the prior art has the following problems during use:
