During production, it needs to be painted. The existing paint coating devices for polyimide film wrapped insulated wires, such as a paint coating device for polyimide film wrapped insulated wires disclosed in the application number CN201920769604.0, by setting a stirring shaft and stirring blades, when painting the insulated wire, the stirring motor drives the stirring shaft to rotate, so that the stirring blades fixed on the outer side of the stirring shaft stir the paint in the stirring material box, saving manpower and making the paint stirred more evenly, improving the use effect of the paint.

[0003] However, in the actual painting process, in addition to the influence of the uniformity of the paint itself, the spraying method will also affect the coating on the surface of the insulated wire.
