[0037] Specifically, first refer to Figure 1 It shows the main structure of the movable compression roller assembly related to the embodiment. Refer to Figure 2, the rotating roller 1 is a cylindrical member extending along the first direction, and two first shafts 2 are formed at the two ends of the rotating roller 1 in the first direction, the first shafts 2 can be inserted into corresponding shaft holes on the machine table, so that the rotating roller 1 is rotatably installed on the machine table. The part between the two first shafts 2 forms a sliding part 3, the outer diameter of the sliding part 3 is larger than the outer diameter of the part of the first shaft 2, and a second threaded hole 11 is formed on the inner side of the two end faces of the sliding part 3 in the first direction. Referring to Figure 3 , the second threaded hole 11 can be arranged in multiple on the end face of the sliding part 3 in the circumferential direction, so as to improve the stability of the connection between the support ring 9 and the rotating roller 1. Meanwhile, referring to Figure 2 and Figure 3 , a locking groove 4 is arranged on the outer circumferential surface of the sliding part 3 of the rotating roller 1, the locking groove 4 extends along the first direction, and the groove width of the locking groove 4 gradually decreases from the groove opening to the groove bottom. That is to say, the distance between the two side walls of the locking groove 4 is shorter as the depth of the groove is deeper.

In this way, the movable pressing roller assembly can adjust the position of the two pressing rings 5 on the rotating roller 1 according to the width of the film material, so that the pressing ring 5 is only pressed on the edge position in the width direction of the film material, thereby avoiding the foam glue and other components in the middle position of the film material. The design that the groove width of the locking groove 4 gradually decreases from the groove opening to the groove bottom makes it difficult for the first fastener to loosen itself after being screwed in, thereby ensuring the stability of the pressing ring 5 during long-time operation; and this design also helps to accurately position the locking position of the first fastener, so that the first fastener remains relatively centered on the locking groove 4, thereby improving the locking stability.

[0039] A support ring 9 is fixedly installed at both ends of the sliding portion 3 of the rotating roller 1 by a second fastener. The support ring 9 is a circular ring member which can be sleeved on the rotating roller 1.

The rotation axes of the two transmission gears 10 are consistent with the rotation axis of the support roller 7, and the outer circumferential surfaces of the two transmission gears 10 are tooth surfaces. After the movable pressure roller assembly is installed on the machine table, a drive motor on the machine table can be drivingly connected to the support roller 7 through a transmission mechanism, so as to drive the support roller 7 to rotate relative to the machine table.

Specifically, after the movable compression roller assembly is installed on the machine table, the outer circumferential surface of the supporting ring 9 on the rotating roller 1 is pressed against the outer circumferential surface of the supporting roller 7, and the transmission gears 10 on the rotating roller 1 and the supporting roller 7 in positions corresponding to each other are in meshing engagement, so that the rotating roller 1 is driven to rotate synchronously while the supporting roller 7 rotates. The film material is placed between the supporting roller 7 and the rotating roller 1, and the pressing ring 5 is pressed against the film material, so that the film material is conveyed by the clamping of the pressing ring 5 and the outer circumferential surface of the supporting roller 7 and is cut by the die cutter.
