The first pressing roller 105 realizes the effect of effective lamination of paper and film, and the second pressing roller 106 further compacts the film after trimming to prevent the film from warping after trimming by the cutter 503. The support shell 103 is arranged above the positioning frame 101, and the support shell 103 supports the paper;

[0040] In the embodiments of the present disclosure, reference Figures 1 to 8As shown, a group of guide rollers and a winding roller are installed on the top of the positioning frame 101. The guide rollers and the winding rollers cooperate with each other to achieve the effect of film guiding. A group of pressing structures 2 and a group of scanning mechanisms 3 are installed on the inner side of the positioning frame 101. The pressing structure 2 is composed of a stabilizing sleeve 201, a first pushing cylinder 202, and a rubber block 203. The stabilizing sleeve 201 is arranged at the upper position of the positioning frame 101. A first pushing cylinder 202 is installed on the inner side of the stabilizing sleeve 201. The stabilizing sleeve 201 and the first pushing cylinder 202 are firmly connected. The first pushing cylinder The push rod 202 has a thread groove at the bottom, and a rubber block 203 with a thread block is installed at the position of the thread groove.
