[0035] Working principle: In the furniture production process, it is necessary to grind and trim the side edges of the small-volume furniture panels 6 after cutting. The staff first starts the rotating motor 73, so that the rotating motor 73 drives the active rotating drum 71 to rotate through the active shaft 712, and the active rotating drum 71 will drive the grinding belt 72 to rotate. At this time, the grinding belt 72 will drive the driven rotating drum 711 to rotate, so that the rotation stability of the grinding belt 72 is better. At the same time, the active shaft 712 will also drive the active pulley 88 to rotate together, so that the active pulley 88 drives the driven pulley 86 to rotate through the transmission belt 87, and then the driven pulley 86 drives the suction fan blades 83 to rotate through the driven shaft 85. At this time, the rotating suction fan blades 83 will blow air upwards; then the staff can place the small-volume furniture panel 6 on the upper end surface of the support plate 3 and push it to the rear side (reference Figure 1 ), so that the rear end surface of the furniture board 6 contacts the rotating grinding belt 72 for grinding and trimming. During this process, the staff needs to hold the left and right sides of the furniture board 6 with both hands respectively to prevent the furniture board 6 from being greatly displaced to the left and right during the grinding and trimming process. While the furniture board 6 is being ground and trimmed, the rotating suction fan blades 83 will suck most of the dust below through the air guide cavity 11 and blow it to the upper side of the air guide shell 81, and the air guide shell 81 will guide the dust to the outside air filter through the dust guide hose 82 for filtration, thereby avoiding A large amount of dust generated during the grinding and trimming process floats around and endangers the lung health of the workers; in the later use process, when the grinding belt 72 needs to be disassembled and replaced, the staff only needs to loosen the adjusting nut 75 with the help of an external wrench to separate it from the adjusting screw 74. At this time, the support seat 77 can be moved inward, and the support seat 77 will drive the driven rotating drum 711 to move inward through the follower plate 78 and the connecting shaft 79, thereby reducing the distance between the driven rotating drum 711 and the active rotating drum 71, and then the grinding belt 72 can be disassembled and replaced.
