Guide blocks 64 are respectively fixedly arranged on both sides of the sliding block 63, which can stably guide the sliding block 63. A second threaded bolt 65 is fixedly arranged at the upper end of the sliding block 63 through a bearing. The second threaded bolt 65 is threadedly sleeved with the second sleeve block 61 and extends to the outside, facilitating the limiting of the limiting component 6, thereby facilitating the adjustment of the position of the cleaning component 5.

[0032] As Figure 1 and Figure 4 shown, the film laminating component 7 includes a bracket 71, and the bracket 71 is arranged in an "n" shape. A transmission roller 72 is rotatably arranged between the brackets 71 through a bearing. Mounting grooves 73 are respectively formed on both sides of the bracket 71, and the mounting grooves 73 are symmetrically arranged. A fixing rod 74 is fixedly arranged inside the mounting grooves 73. A socket block 75 is movably sleeved on the outer wall of the fixing rod 74, which can stably guide the socket block 75. A connecting plate 76 is fixedly arranged between the socket blocks 75. A pressing roller 77 is rotatably arranged at the lower end of the connecting plate 76. A threaded adjusting rod 78 is rotatably arranged at the upper end of the connecting plate 76. An adjusting cap is fixedly connected to the upper end of the threaded adjusting rod 78, facilitating the manual rotation of the threaded adjusting rod 78. The threaded adjusting rod 78 is threadedly sleeved with the bracket 71, facilitating the adjustment of the height of the pressing roller 77. A second spring 79 is sleeved on the outer wall of the fixing rod 74. One end of the second spring 79 is fixedly connected with the inner wall of the mounting groove 73, and the other end of the second spring 79 is fixedly connected with the socket block 75, increasing the stability of the vertical movement of the socket block 75.

[0033] Furthermore, a collection box 8 is fixedly provided on the upper surface of the bottom plate 1, and the collection box 8 is located between the support frames 2, so as to centrally collect the scraped glue and facilitate processing.

[0034] The working principle of this embodiment is as follows: when in use, the paper product and the coating film are simultaneously passed through the driving roller 72 and the connecting plate 76 and connected to the winding roller. Then, the threaded adjusting rod 78 is rotated by the adjusting cap, and the threaded adjusting rod 78 drives the connecting plate 76 to move vertically downward, and the connecting plate 76 drives the pressing roller 77 to move vertically downward, so that the glued paper product and the coating film are pressed together, thereby quickly coating the film.

[0035] Furthermore, the scraper 511 is moved according to the conveying height of the paper product, so that the snap-in on one side of the scraper 511 maintains a horizontal height with the side of the paper product, and the first threaded bolt 505 is manually rotated, and the first threaded bolt 505 is engaged and moved horizontally through the first sleeve block 504, and the first threaded bolt 505 drives the connecting block 506 to move horizontally, and the connecting block 506 drives the clamping block 507 to move horizontally, so that the clamping block 507 pulls the ring 509 through the annular groove 510, so that the ring 509 and the second guide rod 508 are frictionally limited.

[0036] Furthermore, the limiting assembly 6 is moved according to the width of the paper product, so that the limiting assembly 6 drives the scraper 511 to move horizontally through the connecting frame 501. During the movement of the scraper 511, the light rod 512 is manually pulled so that the light rod 512 drives the scraper block 513 to move vertically. After the scraper 511 moves to both sides of the paper product, the light rod 512 is released, and the light rod 512 pulls the fixed block 514 through the first spring 515, and the fixed block 514 drives the scraper block 513 to move relatively, clamping both sides of the paper product. After clamping, the second threaded bolt 65 is manually rotated, and the second threaded bolt 65 moves vertically downward by engaging with the second set block 61, and the second threaded bolt 65 drives the sliding block 63 to move vertically downward in the sliding groove 62, so that the sliding groove 62 is stably clamped on the outer wall of the first guide rod 4, thereby limiting the scraper 511.

[0037] Finally, during the conveying process of the paper product lamination, the scraper block 513 is used to clamp and scrape off the excess glue squeezed out from the side of the paper product. The scraped glue is guided and conveyed by the inclined surface of the scraper block 513 to fall into the collection box 8 for centralized collection.

[0038] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
