[0002] The enameling machine is a machine that slowly coats insulating varnish on the surface of metal wires and solidifies it. It is an important equipment for the electromagnetic wire industry to produce enameled wires. Its function is to evenly wrap a layer of insulating polyvinyl varnish on the outside of the annealed and softened copper wire or aluminum wire. During the production and processing of the enameled wire, the enameled wire needs to be fed. For the feeding of the enameled wire, the traditional feeding method is that the motor and the wire feeding frame cooperate to transport the enameled wire.
