[0034] 2. In specific use, the operator can place the winding core 7 for winding the film roll between the top body 653 and the fixed support frame 66, and control the working cylinder 651 to start.

When the winding core 7 moves to the preset position driven by the mobile bearing mechanism 6, the other side of the cylinder body 81 can be inflated to make the cylinder rod 82 in a dynamically controlled position state. At this time, when it is necessary to adjust the spacing between the winding core 7 and the winding roller body 33, the operator can control the air pressure on both sides of the cylinder body 81. The change of the air pressure on both sides of the cylinder body 81 realizes the dynamic change of the expansion and contraction amount of the cylinder rod 82. The dynamic change of the expansion and contraction amount of the cylinder rod 82 will drive the movement change of the mobile bearing mechanism 6, thereby realizing the change of the spacing and contact pressure between the winding core 7 and the winding roller body 33, so that the film roll on the winding core 7 can always maintain a stable, accurate and controllable contact pressure with the winding roller body 33 during the winding process.
