The main shaft 5 is arranged vertically through the frame 7. The first motor 6 is fixedly connected to the bottom of the frame 7 through a bracket.

[0028] A plurality of uniformly distributed first rotating shafts 2 are installed on the turntable 1 near its circumferential position. The first rotating shafts 2 are arranged vertically through the turntable 1. The first rotating shafts 2 are rotatably connected to the turntable 1 through bearing seats. The top ends of the first rotating shafts 2 are used to install the pulley 3 to be polished. The pulley 3 is connected to the first rotating shaft 2 through a flat key, which is convenient for installation and disassembly. The bottom ends of the first rotating shafts 2 are respectively installed with first gears 4. The first gears 4 drive the first rotating shafts 2 and the pulleys 3 to rotate at high speed along the bearing seats in sequence.

[0029] The side of the frame 7 is installed with a second rotating shaft 8, a third rotating shaft 9 and a fourth rotating shaft 10 that are sequentially connected in transmission. The second rotating shaft 8, the third rotating shaft 9 and the fourth rotating shaft 10 are all arranged vertically through the frame 7.
