Problems solved by technology

The invention can solve the problem that when the existing wires and cables are wrapped, it is usually impossible to wrap multiple wrapping materials at the same time, resulting in poor processing effect and low efficiency of the wire core, and it is impossible to wrap the surface of the wrapping material. Glue coating affects the adhesion effect of the wrapping material. At the same time, when the existing wire and cable are wrapped, the angle of the wrapping material is usually fixed, which cannot effectively adjust the winding angle of the wrapping material accurately. Difficulties affecting the preparation effect of cables

[0003] However, there are also some problems in the wire and cable preparation process. For example, the produced cable has poor compressive performance, and the permanent deformation rate of the finished cable is high after long-term compression, which is likely to cause damage to the wires inside the cable and affect the normal operation of the cable. Low pressure resistance
