Background

The enamelling machine is important equipment for producing enamelled wires in the electromagnetic wire industry and has the function of uniformly wrapping a layer of insulating paint on the outer surface of a processed copper wire. The enameled wire paint used in the production of the enameled wire is hard poly-vinegar paint (mainly comprising dimethyl vinegar, glycol and glycerol), and is dissolved by organic solvents (mostly cresol and xylene) to form liquid enameled paint, and the liquid enameled paint is uniformly dipped and coated on a copper wire in the production of the enameled wire, and then is dried to enable the organic solvents or water to be rapidly volatilized. Because a small amount of wire drawing oil is attached to the copper wire to be coated with the paint, the wire drawing oil contains a small amount of copper powder, the copper wire enters the wire inlet through hole, and finally is led out from the outlet end of the wire inlet through hole after the copper wire sequentially passes through the structures of annealing, washing, drying, coating with the paint, baking the paint and the like. Because in the drying process after washing, vapor escapes from the inlet end of the wire inlet through hole, the wire drawing oil volatilizes in the annealing process, the wire drawing oil is easy to condense to form a viscous black mixture, the viscous black mixture is adhered to the inlet section of the wire inlet through hole, a subsequently fed copper wire is easy to contact with the mixture, more mixture is adhered to the copper wire, the copper wire adhered with the mixture is difficult to remove in an annealing and washing structure after entering an enameling machine, and finally enters an enameling structure, the copper wire adhered with the mixture is coated by the enameling machine, and finally, the wire is drawn out by baking, the black spots are formed at the corresponding part of the mixture adhered to the copper wire, so that the qualification rate of the copper wire enameling. Therefore, there is a need for a copper wire enameling apparatus that prevents black spots.
