Description

Technical Field

[0001] The utility model belongs to a paint scraping device, in particular to an enameled wire paint scraping device. Background Art

[0002] Enameled wire is a main type of winding wire, which consists of a conductor and an insulating layer. After the bare wire is annealed and softened, it is painted and baked many times. Enameled wire is often used in the electrical and motor industries. During use, the insulating paint on the exposed end of the enameled wire on the coil must be thoroughly removed before welding. If the insulating paint is not thoroughly removed, it will lead to poor welding and problems such as cold welding during welding. There are many ways to remove insulating paint, including manual paint scraping, mechanical paint scraping, and the use of paint strippers, but manual paint scraping is slow and labor-intensive. For thick enameled wires, you can use a knife or a broken saw blade to scrape off the paint one by one. When scraping, do not scrape only two sides, but scrape carefully along the circumference of the circle, and do not scratch the wire. This method is called scraping paint removal.
