Description

Technical Field

[0001] The invention relates to the technical field of coating equipment, in particular to an automatic hot wax coating equipment for enameled wires. Background Art

[0002] Enameled wire is a manufacturing process product of wires and cables. It is mainly used for internal connection of electronic equipment and electrical equipment. Enameled wire is a main type of winding wire, which consists of two parts: conductor and insulation layer. The bare wire is annealed and softened, and then painted and baked several times. According to the type of insulating paint, enameled wire can be divided into polyurethane enameled wire, polyesterimide enameled wire, polyimide enameled wire, polyamideimide enameled wire and other types. Each enameled wire has its own unique performance and application field.

[0003] The automatic hot wax coating equipment for enameled wire heats the solid paraffin in the wax melting container through the electric heating tube to melt it into liquid state. The liquid paraffin is transported to the oiling bucket through the oil spraying pipe. At the same time, the compressed air is sent to the oiling bucket through the jet pipe to atomize the liquid paraffin. The atomized paraffin can be sprayed more evenly on the adsorption felt, and the finished enameled wire passes through the adsorption felt to achieve paraffin lubrication coating.

[0004] When using the existing automatic hot wax coating equipment for enameled wires, dirt, grease, oxides or other impurities may exist on the surface of the enameled wires during the production and transportation process.

[0045] The cleaned enameled wire will be dried under the action of the sponge sleeve 602, and further dried and heated under the action of the electric heating wire 101, so that the device can preheat the enameled wire before coating, which can effectively prevent the rapid solidification of paraffin wax, improve the adhesion of paraffin wax on the enameled wire and the coating effect, and then the liquid paraffin will be injected into the wax guide ring 302 through the wax guide tube 301, and then sprayed out through the coating nozzle 304 on the coating ring 303.
