[0006] The scraper is tightly connected by the protrusions between adjacent grooves; the opposite grooves I and II form a negative pressure dust extraction air duct, and a negative pressure dust extraction air hopper is provided at the end of the negative pressure dust extraction air duct.
[0007] Furthermore, the groove I and the groove II are opposite to each other to form a V-shaped structure, and the negative pressure dust extraction scoop is located at the wide end of the V-shaped structure.
[0008] Furthermore, the groove I and the groove II are opposite to each other to form a triangular structure, one of the tips of the triangular structure is opposite to the roller, and the negative pressure dust extraction duct is located at the wide side opposite to the tip.
[0009] Furthermore, the negative pressure dust extraction scoop is fixedly mounted on the scraper mounting seat.
[0010] Furthermore, the scraper mounting seat is a long plate with a long slot hole; the slot I is located in the long slot hole, and its extension direction is parallel to the central axis of the long slot hole.
[0011] Furthermore, the scraper is made of flexible material; the scraper and the scraper pressing plate are both located in the long slot hole.

[0013] The utility model invents a V-shaped negative pressure dust extraction channel on the scraper mounting seat and the scraper pressure plate. 1. The dust and accumulated liquid scraped off by the scraper can smoothly fall into the negative pressure dust extraction channel and be extracted by the negative pressure. The use effect of the scraper is better and the roller surface is cleaner. 2. The negative pressure exhaust hopper and the scraper are integrated to reduce the loss of negative pressure and make the efficiency of negative pressure dust extraction higher. 3.
