Coating by dipping insulating paint and other materials is a common method, for example, passing the wire to be coated through the anti-corrosion coating circulation tank, so that the anti-corrosion coating adheres to the wire to complete the coating. However, because the wire passes through the anti-corrosion coating circulation tank faster, the coating of the anti-corrosion coating is uneven, which affects the coating quality, and needs to be improved urgently.
