The pressure roller is released, and the elastic connecting frame is reset, so that the pressure roller presses the film. Then, during the film rolling process, the pressure roller rotates under the drive of the film, and the pressure roller will continue to press the film downward to smooth it, so that the film is not easy to wrinkle;

[0021] The locking device comprises a plurality of sector blocks 7 and a locking wheel 9 fixedly connected to the side wall of the movable ring 4. There is a gap between two adjacent sector blocks 7, and a trumpet-shaped opening is formed at one end of the sector block 7 away from the movable ring 4, so that the locking wheel 9 with the opening gathered is sleeved on the outer wall of the sector block 7.

[0022] When it is necessary to smooth films of different widths, first loosen a part of the locking wheel until the tightness reaches the level that allows the movable ring to be moved. The second slider between the inner walls of the movable ring moves along the slide groove, and then the two movable rings are moved in opposite directions to separate the horizontal part of the elastic connecting frame from the mounting groove of the pressure roller, thereby removing the pressure roller and then selecting a pressure roller of appropriate length for replacement according to the actual film size.

[0023] The elastic connecting frame 5 further includes a connecting portion 51 fixedly connected to the movable ring 4, a vertical portion 52 and a horizontal portion 53.

[0028] By providing a slide groove on the roller body, the movable ring has a second slider that cooperates with the slide groove and a first slider that is slidably connected to the outer wall of the roller body. This not only facilitates the adjustment of the distance between the two movable rings for installing pressure rollers of different lengths, but also can adapt to the pressing requirements of films of different lengths, thereby expanding the application range of the device. It also reduces the gap between the movable ring and the roller body, improves the stability of the movable ring, and is beneficial to improving the position accuracy of the pressure roller, thereby ensuring the pressing and smoothing effect on the film.

[0029] The locking device comprises a plurality of sector blocks 7 and a locking wheel 9 fixedly connected to the side wall of the movable ring 4. There is a gap between two adjacent sector blocks 7, and a trumpet-shaped opening is formed at one end of the sector block 7 away from the movable ring 4, so that the locking wheel 9 with the opening gathered is sleeved on the outer wall of the sector block 7.

[0030] Place a suitable pressure roller between the two movable rings, and then adjust the positions of the two movable rings so that the horizontal part of the elastic connecting frame is embedded in the installation groove of the pressure roller, and the pressing center of the pressure roller is consistent with the moving position of the film, and then re-lock the locking wheel and the four fan-shaped blocks to complete the limiting of the movable rings and ensure that the pressure roller can press and smooth the film.
