Abstract
This utility model relates to the field of sand mill technology, specifically a sand mill for improving ink grinding efficiency. It includes a sand mill body, a grinding cylinder, a servo motor, a lead screw, a first fixed block, a first vertical plate, a connecting plate, a moving block, a first limiting block, and a movable door. In operation, the servo motor rotates, causing the lead screw to rotate under the combined action of the first fixed block, the first vertical plate, and the connecting plate. Simultaneously, as the lead screw rotates, the moving block, threadedly connected to the lead screw, moves linearly along the lead screw, carrying the first limiting block and the movable door with it. This allows for the opening and closing of the movable door and the grinding cylinder. This design makes opening the movable door more convenient, shortens the overall maintenance time inside the grinding cylinder, and thus increases the ink grinding working time and efficiency. Furthermore, the device has a simple operating logic, is stable in use, and is easy to maintain.
