[0001] This utility model relates to the field of cleaning technology in grinding wheel production, and in particular to a mandrel cleaning device for resin grinding wheel production. Background Technology

[0002] In the resin grinding wheel production process, the mandrel, as a core component of the molding die, directly affects the precision, balance, and service life of the grinding wheel product due to its surface cleanliness. Traditional mandrel cleaning methods have the following problems: Poor adaptability to specifications: Existing cleaning equipment mostly adopts a fixed structure, and the position of the scraper or brush is not adjustable, making it difficult to adapt to mandrels of different diameters and lengths and matching material boxes. When the specifications of the mandrel change, frequent tooling changes or equipment adjustments are required, leading to production interruptions. Furthermore, resin debris can easily remain in cleaning dead corners, affecting the consistency of product quality. For example, the patent with publication number CN213352125U, entitled "A Mandrel Cleaning Device for Resin Grinding Wheel Production," suffers from the aforementioned problems.
