[0002] A backing machine (also known as a labeling machine) coats a roll of packaging paper, label paper, etc. with glue on its surface through a laminating machine, then conveys it to a cutting mechanism for cutting, and finally pastes it on the corresponding product.

[0003] In the prior art, when a laminating machine coats glue on the surface of paper through a rubber roller, the phenomenon of uneven glue coating on the paper surface often occurs, thus affecting the product quality. Summary of the Invention

[0004] The present invention is to overcome the deficiency of uneven glue coating on the paper surface in the prior art, and provides a laminating machine which is beneficial to improving the evenness of glue coating on the paper surface.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions: A laminating machine, which comprises: A frame, the left side of the frame is the feeding end, and the right side of the frame is the discharging end; An upper glue roller, rotatably connected to the front and rear sides of the frame, and the upper glue roller rotates upward from the feeding end towards the discharging end; A lower glue roller, rotatably connected to the front and rear sides of the frame, and rotating synchronously and reversely with the upper glue roller, and the top of the lower glue roller is in contact with the upper glue roller; A glue box, detachably connected to the bottom of the frame, and the bottom of the lower glue roller is located in the glue box; A first roller, rotatably connected to the feeding end of the frame, and located obliquely above the upper glue roller, and the first roller is parallel to both the upper glue roller and the lower glue roller; A second roller, rotatably connected to the feeding end of the frame, and located obliquely below the upper glue roller, and the first roller and the second roller are parallel to each other and are obliquely distributed; The scraping knife is detachably connected to the feeding end of the frame and is located on the sides of the first roller and the second roller. The scraping knife contacts the side wall of the glue applying roller through its cutting edge. A rolled paper tray is located on the left side of the frame. The paper bypasses the bottom of the second roller and the top of the first roller in sequence and then contacts the top surface of the glue applying roller, and finally is output from the right side of the frame. During this process, the lower glue roller rotates from the discharging end upward towards the feeding end, and the upper glue roller rotates reversely from the feeding end upward towards the discharging end. The lower glue roller applies the glue in the glue box onto the upper glue roller through its rotation, and then the redundant glue on the upper glue roller is scraped off by the scraping knife to control the thickness of the glue to be applied onto the paper surface, achieving the purpose of facilitating the improvement of the uniformity of the glue coating on the paper surface and improving the product quality.

[0006] Preferably, a first pull rod is provided at the feeding end of the frame. The first pull rod is parallel and corresponding to the upper glue roller.

The clamping plate is arranged in a downward inclination towards the lower glue roller. One side of the scraping knife is detachably connected to the clamping plate, and the cutting edge is located on the other corresponding side of the scraping knife and contacts the bottom of the upper glue roller. The clamping plate being arranged in a downward inclination towards the lower glue roller is beneficial to improving the effect of the scraping knife scraping off the redundant glue through its cutting edge. The redundant glue returns to the glue box, which is beneficial for recycling and cost saving.

[0007] Preferably, there are several clamping plates. The several clamping plates are distributed along the length direction of the first pull rod. The clamping plates are slidably connected to the first pull rod. There are several scraping knives, and the several scraping knives are respectively matched with the several clamping plates.
