When the first limit ring block 76 moves to the required position, the staff can rotate the second bidirectional screw 101. When the second bidirectional screw 101 rotates, it can smoothly drive the two second limit ring blocks 102 to move together. When the two second limit ring blocks 102 move to the required position, the staff can start the servo motor 24 to drive the connecting ring block 31 and the winding roller 32 to rotate, so that the winding roller 32 can realize the winding of the PET sheet by rotation.

[0038] At the same time, the staff can rotate the one-way screw 81 so that the one-way screw 81 drives the first rotating roller 83 to move downward through rotation. When the first rotating roller 83 moves to a certain distance, it can cooperate with the second rotating roller 84 to clean the PET sheet through the cleaning pad 85.

[0039] When the PET sheet rolled up on the outside of the winding roller 32 needs to be removed, the bolt rod 23 only needs to be taken out from the inner side of the connecting shaft 21 and the insert plate 22 to remove the winding roller 32 and the connecting ring block 31, and at the same time, the PET can be taken out.
