The two clamping plates 381 on both sides of the workpiece clamp the workpiece. The driving motors 6 on both sides of the workpiece are started at the same time to drive the threaded rod 4 to rotate. The threaded rod 4 cooperates with the threaded hole 32 to work, and the lifting plate 31 rises on the threaded rod 4. At the same time, the lifting plate 31 rises on the positioning rod 5 through the positioning hole 33, driving the workpiece to rise together.

When one side of the workpiece is completed After the impurities are removed, the front motor 36 is started to drive the driving gear 37 to rotate. Through the mutual engagement between the driving gear 37 and the docking gear 385, the driving gear 37 drives the docking gear 385 to rotate. The rotation of the docking gear 385 drives the clamping plate 381 to rotate through the conveying shaft 384, so that the workpiece is turned over, and then the driving motor 6 drives the threaded rod 4 to reverse, the lifting plate 31 descends on the threaded rod 4, the hydraulic push rod 34 retracts to place the workpiece back on the conveyor belt, and the front motor 36 drives the driving gear 37 to reverse so that the clamping plate 381 flips and resets, and the clamping plate 381 clamps the workpiece again, but at this time the clamping position of the clamping plate 381 on the workpiece is staggered with the initial clamping position. After clamping the workpiece, the impurities removal work is performed again, so that the workpiece obtains a comprehensive impurity removal effect.
