The second edge scraping component 2 includes a second cutting saw 21 for cutting the board and a second edge scraping saw 22 for crushing the cut edges. The second cutting saw 21 and the second edge scraping saw 22 are fixedly connected together, and the second cutting saw 21 and the second edge scraping saw 22 rotate together. The mutual cooperation between the first edge scraping component 1 and the second edge scraping component 2 makes the gypsum board 3 to be cut more uniformly, and the gypsum board 3 will not be deformed during cutting. The first cutting saw 11 and the second cutting saw 21 rotating at high speed can quickly and evenly cut the edge of the gypsum board 3, and the face paper has no burrs when cutting and there will be no paper delamination.

[0028] The first edge crushing assembly 1 and the second edge crushing assembly 2 are arranged in a front-to-back staggered manner, the first edge crushing assembly 1 is arranged above the second edge crushing assembly 2, and the second edge crushing assembly 2 is arranged behind the first edge crushing assembly 1. When the gypsum board 3 to be cut is conveyed by the conveying mechanism, the second edge crushing assembly 2 first contacts the gypsum board 3. The first edge crushing assembly 1 and the second edge crushing assembly 2 rotate in opposite directions, and the second edge crushing assembly 2 first cuts the gypsum board 3. The horizontal height of the top of the second cutting saw 21 is located between the upper and lower surfaces of the conveyed gypsum board 3, and the horizontal height of the lowest point of the first cutting saw 11 is lower than the horizontal height of the bottom surface of the conveyed gypsum board 3. When the second cutting saw 21 cuts the gypsum board 3, the gypsum board 3 cannot be completely cut off, and the first cutting saw 11 can completely cut off the gypsum board 3, so that the powder generated by cutting and crushing the edge of the gypsum board 3 is mainly concentrated at the bottom of the gypsum board 3, reducing the dust in the workshop.

[0029] The first cutting saw 11 includes a first cutting saw body 111 and a plurality of first saw teeth 112 arranged in a ring on the first cutting saw body 111.
