[0002] When processing furniture, the edges and corners of the boards are relatively sharp and burrs are likely to remain after cutting, so the boards need to be chamfered first.

[0003] A Chinese patent discloses a plate corner grinding device for building material processing, with the publication number CN214519408U, comprising a bottom plate, a front-and-rear moving mechanism is arranged on the left side of the top of the bottom plate, a vertical frame is installed on the front-and-rear moving mechanism, a horizontal plate is arranged on the middle and upper right side of the vertical frame, and an active roller and a driven roller are arranged on the front side of the vertical frame for corresponding rotation up and down, a driving motor is connected to the rear end of the central axis of the active roller, and the active roller and the driven roller are arranged symmetrically about the horizontal plate. The utility model sets the grinding belt to an isosceles triangle working state, and combines with the second telescopic cylinder to complete the grinding of the upper and lower edges of the plate without flipping the plate for installation, and the front-and-rear moving mechanism can drive the grinding belt to move back and forth, thereby increasing the coverage of the grinding area, so as to adapt to plates of different lengths.

[0004] However, there are still the following disadvantages: the device rotates the locking screw to make the pressing plate press the building board, which is convenient for positioning the building board. However, after the left end of the building board is polished, when the right end of the building board needs to be polished, the building board needs to be removed and installed in reverse, which is troublesome. Therefore, we propose a board edge grinding device to solve this problem. Utility Model Content
