Description

technical field [0001] The invention relates to the technical field of cable processing, in particular to a stranded wire insulation extrusion and winding production line. Background technique [0002] The wire production process should ensure that the stranded wire is fully stretched before covering the insulation so that the insulation material can be better attached to the wire and the surface of the insulation is smoother. Otherwise, the insulation material on the stranded wire The adhesion performance is not good, and the surface is difficult to be smooth; it also includes the extrusion process after the wire is covered with an insulating layer. The insulating layer protects the twisted wires inside it and prevents leakage.

[0002] The wire production process should ensure that the stranded wire is fully stretched before covering the insulation so that the insulation material can be better attached to the wire and the surface of the insulation is smoother. Otherwise, the insulation material on the stranded wire The adhesion performance is not good, and the surface is difficult to be smooth; it also includes the extrusion process after the wire is covered with an insulating layer. The insulating layer protects the twisted wires inside it and prevents leakage. If the insulating material is not plasticized uniformly, It will affect the quality of the wire insulation layer, so that the insulation layer is often not smooth enough, there is stress inside, and its mechanical properties are not good; wire winding is the last step in wire processing, and the efficiency of winding is very important. Uneven rewinding often occurs, resulting in fewer wires rewound by each reel and uneven center distribution, which increases the cost of wire storage and the difficulty of transportation; in addition, if the wires before rewinding do not pass through Sufficient stretching, then, the residual stress on the skin and inside of the wire will cause the wire rolled to the reel to crimp and deform, and cannot be tightly combined with the reel, which will also affect the quality and efficiency of wire winding
