[0013] Preferably, the rotating frame is symmetrically arranged on the carding frame with the vertical coaxial line, the two rotating frames are synchronously and oppositely arranged, and the rotating frame and the elastic air bag are also arranged in the relative rotation structure.

[0014] Preferably, the bottom of the carding frame is further provided with a gear disc coaxially distributed with the rotating shaft of the rotating frame, and the outer wall of the gear disc is meshed with the gear of the shaft end of the elastic air bag.

[0040] Based on the above technical scheme, the positioning sheet 401 further fixedly has an electromagnet 403, the electromagnet 403 is arranged in the same magnetic pole repulsion mode corresponding to the permanent magnet on the back of the damping pressing plate 402, and when the one-way position limiter 4 moves to the vertical projection plane and the left side of the combiner 5, the electromagnet 403 limits the damping pressing plate 402 through repelling the permanent magnet, and when the combiner 5 is located, the magnetic action of the electromagnet 403 makes the one-way position limiter 4 be completed to be unfolded and positioned, so that the effect of limiting the PVC film roll is achieved, and even when the PVC film roll and other external loads are applied to the one-way position limiter 4 to compress the external force, the one-way position limiter 4 can remain stable, thereby facilitating the arrangement of the PVC film roll by the combiner 5; why the arrangement of the PVC film roll is needed, please refer to the example of Figure 10 In order to realize the batch conveying and stacking of the PVC film roll, the width of the conveying belt assembly 1 needs to be expanded, so as to facilitate the receiving of the PVC film roll, and when the PVC film roll is not centered and aligned, the subsequent receiving of the lifting assembly 2 will also be affected, and the PVC film roll is easy to be clamped and stacked during the receiving process, so that the combiner 5 is arranged to arrange the PVC film roll.

[0041] In the technical scheme, first, the hydraulic member is arranged on the combiner 5 to drive the combing frame 501 to ascend and descend, and temporarily intercept the PVC film roll.
