A method for automatically removing burrs from a plastic pallet according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: Before use, a conveying motor (102) arranged on the surface of the conveying frame (101) drives the conveying roller (103) to rotate, and the surfaces of the two conveying rollers (103) are connected through a conveying belt (1) to drive the tray above the conveying belt (1) to move to the bottom of the loading and unloading mechanism; Step 2: by rotating the equipment body (2), the lower support plate (202) arranged below the mounting plate (201) is inserted into the interior of the pallet, and the lower support plate (202) is moved upward so that the lower support plate (202) is connected to the surface of the pallet through the anti-slip pad (203) arranged on the surface, and a fixing plate (204) is arranged above the lower support plate (202), and the surface of the fixing plate (204) is fixedly connected to the surface of the upper support plate (206) through a feeding cylinder (208), and the upper support plate (206) is driven by the feeding cylinder (208) to move up and down along the slide groove (205) provided on the surface of the mounting plate (201), and the surface of the pallet is fixedly clamped and then the loading and unloading actions are performed, and the two ends of the guide rod (207) are fixedly connected to the surface of the lower support plate (202) and the surface of the fixing plate (204) respectively, and the surface of the upper support plate (206) is slidably connected to the surfaces of multiple guide rods (207) to maintain the sliding stability of the upper support plate (206); Step 3: The pallet is transferred to the upper part of the positioning platform (4), and the pallet is placed on the surface of the positioning platform (4) by the loading cylinder (208), and the lower support plate (202) is withdrawn from the interior of the pallet, and the upper positioning motor (402) and the lower positioning motor (403) provided on the surface of the positioning platform (4) respectively drive the upper positioning screw (405) and the lower positioning screw (406) to rotate, and the positioning pulleys (407) provided on the surface of the two upper positioning screws (405) are connected by belt transmission, and the positioning pulleys (407) provided on the surface of the two lower positioning screws (406) are connected by belt transmission. The positioning pulley (407) is connected by belt transmission, and the upper positioning motor (402) drives the two upper positioning plates (410) to move in opposite directions along the surface of the positioning groove (409) and the surface of the lower positioning plate (401) through the two upper positioning screws (405), and the lower positioning motor (403) drives the two lower positioning plates (401) to move in opposite directions along the surface of the positioning groove (409) and the surface of the positioning slide bar (404) through the two lower positioning screws (406), so as to clamp and position the four surfaces of the pallet; Step 4: A rotating cylinder (303) is provided at the upper end of the equipment body (2), and the surface of the rotating cylinder (303) is fixedly connected to the surface of the mounting plate (201) through the switching shaft (304). The rotating cylinder (303) is driven to drive the mounting plate (201) to rotate 90 degrees around the axis of the switching shaft (304) through the switching shaft (304), and the lower support plate (202) provided at the lower end of the mounting plate (201) is rotated to the side of the mounting plate (201). At the same time, the mounting seat (301) provided on the side of the mounting plate (201) is rotated to the lower end of the mounting plate (201). An edge grinding motor (302) is provided on the surface of the mounting plate (201). The edge grinding motor (302) drives the edge grinding wheel (3) provided below the mounting plate (201) to rotate through the mounting seat (301), and the edge grinding wheel (3) is used to remove the burrs on the surface of the pallet after clamping and positioning. Step 5: The equipment body (2) drives the edging wheel (3) to move along the surface of the pallet after it is clamped and positioned. After the burrs on the surface of the pallet are removed, the rotating cylinder (303) set on the main body (2) drives the mounting plate (201) to rotate, and the lower support plate (202) is rotated to the bottom of the mounting plate (201). The lower support plate (202) is inserted into the interior of the pallet, and the pallet is clamped by the upper support plate (206) and the lower support plate (202). The pallet is transferred to the unloading area, and the next pallet above the conveyor belt (1) is loaded and deburred.
