Background

Enameled wire is a main variety of winding wire, which is formed by two parts of conductor and insulating layer, and bare wire is annealed and softened, painted for many times and baked. The enameled wire can be divided into flat wire, round wire and hollow wire according to the shape of the material.

Currently, in the production process of enamelled flat wire, a conventional painting process generally sets a painting nozzle above a transmission path of the flat wire to spray paint on the surface of the flat wire, and then feeds the painted flat wire into a drying oven to heat.

However, in the actual production process, there are the following drawbacks:

1. before painting, if the surface of the flat wire is stained with foreign matters, the painting quality is poor, and when the flat wire is sent into a baking oven after painting, the paint layer is easy to crack, and the product yield is low;

2. Because the flat wire is flat, the spraying area formed by the painting nozzle is limited, and paint can be sprayed on one side of the flat wire at a time, at least two painting procedures are needed to finish the coating of the double-sided paint of the flat wire, and the painting efficiency is low;
