Efficient grinding machine for plastic products

The utility model relates to the technical field of polishing, in particular to an efficient polishing machine for plastic products, which comprises a bottom plate, a workbench is slidably mounted on the surface of the bottom plate, a screw rod is mounted on one side of the workbench through a screw rod thread sleeve, a turntable is mounted at one end of the screw rod, and a second clamping plate is rotatably mounted at the other end of the screw rod. A servo motor is installed on the lower surface of the top plate, a rotating shaft is installed at the output end of the servo motor, a first clamping plate is installed at the end, away from the servo motor, of the rotating shaft, a hydraulic cylinder is installed on the lower surface of the top plate, and a polishing disc is installed at the output end of the hydraulic cylinder. And due to the fact that the first clamping plate and the second clamping plate are connected through a sliding column and a storage column, when the first clamping plate rotates, the
