The tops of the slide bars 8 are provided with smoothing plates 9 that fit with the winding roller 3. The design of the smoothing plate 9 can realize the smoothing of the coated substrate, and then the guide rails 2, springs 7 and slide bars 8 can be used to increase the winding of the coated substrate to push the smoothing plate 9, so that the smoothing plate 9 can always fit with the coated substrate in the later stage.

[0028] The middle position of the two sets of mounting plates 6 away from each other is provided with a rotating rod connected to the U-shaped mounting plate 1, and a gear 5 is provided on the outside of one set of rotating rods.

The smoothing of the coated substrate can be realized through the fitting of the smoothing plate 9 and the coated substrate, and the wrinkle phenomenon during winding can be reduced, and the quality of winding in the later stage can be improved. When winding, the amount of coated substrate gradually increases, which can push the smoothing plate 9 to drive the slide bar 8 to move inside the guide rail 2 to realize the compression of the spring 7, so as to ensure that the smoothing plate 9 can always keep fitting and smoothing with the coated substrate;

[0030] When it is necessary to change the roll when winding the coated substrate, the incomplete gear 10 can be rotated by the conversion motor 11. The incomplete gear 10 and the gear 5 are meshed with each other, and the gear 5 can be driven to rotate by the incomplete gear 10.
