This setting is convenient for adjusting the distance between the two grinding panels 6 according to the actual width of the gypsum board. Then, the air inside the hollow box 203 is extracted through the air pump 202 and the air pipe, so that a negative pressure environment is formed inside the hollow box 203. With the cooperation of the through hole 205, the gypsum board is firmly fixed. It is adsorbed on the placement table 204, and finally the first servo motor 13 is started through the controller 21. The first servo motor 13 drives the one-way screw 12 to rotate through the output shaft, so that the one-way screw 12 can rotate forward or reverse. The first slider 9 drives the L-shaped bracket 3 to move forward and backward, so that the grinding panel 6 moves forward and backward to grind the edge of the gypsum board. The collection box 803 is set directly below the grinding panel 6. The debris dropped by the grinding panel 6 when the gypsum board is polished falls into the collection box 803 to prevent the debris from scattering. The grinding panel 6 is prone to wear after long-term use. The nut 7 is turned counterclockwise to remove the grinding panel 6 from the L-shaped bracket 3, so that a new grinding panel 6 can be replaced in time.
