The first driving motor 92 drives the roller to roll on the first slide rail 81, driving the lifting rod 95 to move above the hopper 4. The second driving motor 94 drives the lifting rod 95 to descend through the traction belt 96, so that the height of the buckle 952 in the vertical direction is lower than the clamping part 422. The first driving motor 92 drives the lifting rod 95 to move along the first horizontal direction again, so that the buckle 952 corresponds to the clamping part 422 in the vertical direction. Then, the second driving motor 94 drives the lifting rod 95 to rise through the traction belt 96, so that the buckle 952 is clamped with the clamping part 422. The conveying device drives the hopper 4 to move above the material receiving port 11, so that the bottom shell 41 corresponds to the trigger 3. Then, the hopper 4 is driven to descend. The trigger 3 contacts and supports the bottom shell 41 to open the dropping port, and the materials enter the receiving port 11 from the dropping port. After the feeding is completed, the hopper 4 is driven by the conveying device to move to the initial position. The third driving motor drives the guide roller to rotate, so that the hopper 4 moves to the platform 51 along the first horizontal direction. After grinding, the materials are discharged from the feeding port 12, fall onto the conveyor belt 6 and are conveyed by the conveyor belt 6 to the vibrating screen 71. After the materials are separated by the vibrating screen 71, the finished products fall onto the second slideway 73 and are conveyed to the finished product area. The abrasive is re-conveyed into the hopper 4 through the first slideway 72. The hopper 4 is driven to rotate by the rotating mechanism 5, so that the abrasive is evenly distributed in the hopper 4. After the workpieces are re-fed into the hopper 4, the grinding machine 1 can be loaded again. In this application, the operation of each component can be controlled by the PLC controller, and the loading and unloading operations of multiple grinding machines are carried out in sequence.
