Background In some current film roll packaging processes, a buckling device is used to package and protect two ends of a film roll, and related prior art, such as chinese patent publication No. CN216805951U, is issued. The film roll lifting mechanism (roll supporting device) is used for supporting the film roll and lifting the film roll to a required height position, the height position enables the central spindle of the film roll to correspond to the clamping mechanisms on two sides, a flower disc (or a paper cover) is placed at the end of the roll, the flower disc is wound and fixed through adhesive tape, and a plug is optionally arranged at the end of the spindle. One of the key points of the clamping mechanism is a movement control structure of the clamping jaws on the shrink disk. In the prior art, the connecting rods are adopted for control, the width of each connecting rod can cause interference and blocking between adjacent connecting rods in the jaw shrinkage state, so that the jaw shrinkage stroke is limited and cannot shrink to a position very close to the center of a shrinkage disc, when the clamping mechanism is used, coils with different diameters can be packaged by changing different jaws and shrinkage amplitudes, the problem of limited stroke can cause that one set of equipment cannot package coils with smaller diameters beyond the jaw shrinkage range, and then another set of smaller equipment is needed or manual packaging is adopted, so that the production cost and efficiency are affected. And the film roll lifting mechanism needs to be lifted to different heights based on film rolls with different sizes, and can be adjusted to ensure that the height positions of the two ends of the film rolls are flush.
