It is convenient to scrape off the excess coating on the surface of the coated neodymium iron boron product inside the connecting frame (3). One-time scraping operation saves the trouble of manually turning over the product and then scraping again. At the same time, when the neodymium iron boron product is scraped, the thickness of the coating on the surface of the neodymium iron boron product can be adjusted and controlled according to the needs of the neodymium iron boron product, and the thickness of the coating on the surface of the neodymium iron boron product can be kept consistent. When the excess coating on the surface of the coated neodymium iron boron product is scraped, the excess coating falls from the inside of the connecting frame (3) into the collection tank (12), which is convenient for collection, storage and recycling. After the equipment is used for a long time, the scraper (4) can be quickly disassembled and assembled by adjusting the adjusting assembly (5), which is convenient for subsequent maintenance and cleaning of the staff.
