[0028] A material receiving mechanism for winding up the dust-free cloth is arranged at the top of the side surface of the side panel 2, and the material receiving mechanism includes a second motor 10 and a winding frame 11. The second motor 10 is fixedly mounted on the top of the side panel 2 close to the fixed frame 1, and the output end is connected to a belt through a spur gear transmission, and the other end of the belt is transmission connected to the winding frame 11 through a spur gear, and the winding frame 11 is rotatably connected to the top of the side panel 2 away from the fixed frame 1. A material discharging mechanism for placing the dust-free cloth is arranged in the middle of the side surface of the side panel 2, and the material discharging mechanism includes a third motor 12 and a placing frame 13. The third motor 12 is fixedly mounted on the middle of the side panel 2 close to the fixed frame 1, and the output end is connected to a belt through a spur gear and a belt through a spur gear.

The unused dust-free cloth roll is sleeved on the outside of the placement rack 13, and one end of the opening passes through the bottom of the pressing mechanism and is fixed on the winding rack 11. The second motor 10 drives the winding rack 11 to rotate so that the dust-free cloth can be wound on the winding rack 11. At the same time, the third motor 12 drives the placement rack 13 to rotate in the direction of releasing the dust-free cloth, so that the dust-free cloth can be progressively replaced, so that the used dust-free cloth at the bottom of the pressing mechanism moves toward the winding rack 11, and the dust-free cloth to be cleaned subsequently is moved to the bottom of the pressing mechanism, so as to clean the next batch of polarizers;

[0029] An adjustment mechanism for adjusting the dust-free cloth is arranged between the unloading mechanism and the receiving mechanism, and the adjustment mechanism includes a first fixed plate 14, a first electric telescopic rod 15, a first movable frame 16, an adjustment rod 17 and a first limit rod 18.
