Description

Technical Field

[0001] The utility model relates to the technical field of edge banding machines, in particular to a scraper assembly for edge banding machines. Background Art

[0002] After the board edge is banded, use a scraper to remove excess edge material to ensure that the board edge is flat and smooth.

[0003] In the prior art, the scraper is usually tightened to the blade holder by only a single screw. When in use, the scraper applies cutting force to the edge banding material on the board, which can easily cause the scraper to loosen and rotate, changing the scraping angle of the scraper. This will not only affect the flatness and smoothness of the edge of the board, but may also cause the following problems: if the scraping angle is too large, the scraper will scrape the board together and damage the edge of the board; if the scraping angle is too small, it will be difficult to completely remove the edge banding material, resulting in burrs on the edge of the board, affecting the appearance and use, and may even bring safety risks.
