Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, specifically to a paint stripping device and a paint stripping machine. Background Technology

[0002] Enamelled wire is a major type of winding wire, consisting of a conductor and an insulation layer. The bare wire is annealed and softened, then coated with enamel multiple times and baked. During use, the insulating enamel at the ends of the enamelled wire must be completely removed before soldering. Traditional manual enamel scraping is slow, labor-intensive, and often results in incomplete scraping, requiring repeated rework and leading to low efficiency. Furthermore, due to different production specifications, the wire diameter varies, necessitating a blade structure adaptable to different wire diameters, coupled with automated equipment, to achieve efficient enamel removal. Therefore, an enamel removal device and machine have been developed. Utility Model Content
