Description

technical field [0001] The invention relates to the technical field of wire surface coating, in particular to a wire surface spraying device. Background technique [0002] Surface coating technology refers to the technology of coating a layer of new materials on the surface of materials to improve surface properties, such as electroplating, painting, thermal spraying and vapor deposition technology, etc. In the production process of wire used for electrical conduction, it is often necessary to coat the surface of the wire to improve the insulation, wear resistance, waterproof, and oxidation resistance of the wire surface, which is usually achieved by dipping, brushing, and sheathing. . Due to the special material on the surface of some special wires, when traditional dipping and brushing processes are used, the surface materials of the wires are prone to softening, damage, shedding, and structural damage during the process of water absorption, friction, or stress.

AI Technical Summary

Problems solved by technology

Due to the special material on the surface of some special wires, when traditional dipping and brushing processes are used, the surface materials of the wires are prone to softening, damage, shedding, and structural damage during the process of water absorption, friction, or stress. The integrity, uniformity and density of the wire surface are compromised, resulting in greatly reduced performance of the coating layer, and the quality of the wire cannot be guaranteed

Therefore, it is necessary to design a wire surface spraying device to minimize the contact with the wire surface material during the coating process, so as to prevent the wire surface material from softening, breaking, falling off, and structural damage, which will affect the performance of the coating layer.
