Description

Technical Field

[0001] The utility model relates to the technical field of logistics coding, in particular to a coating device for a paper mounting machine. Background Art

[0002] Paper laminating machines are specially used to glue two different surface materials, base material and cover paper, together by gluing. According to their automation level, paper laminating machines can be divided into three types: manual paper laminating machines, semi-automatic paper laminating machines and fully automatic paper laminating machines. Manual paper laminating machines are operated manually, semi-automatic paper laminating machines are completed through semi-automatic programs, and fully automatic paper laminating machines are completely completed automatically by computer programs.

[0003] When applying glue to the surface of paper, the glue may be unevenly applied. The uneven application of glue on the paper will affect the mounting effect. In addition, the uneven application of glue will result in excessive glue on the paper surface, which will waste glue and increase production costs.

[0004] Therefore, we propose a coating device for a paper mounting machine to solve the above problems. Utility Model Content

[0007] The surface of the glue box is provided with two sets of sliding grooves, and the inner cavities of the sliding grooves are slidably connected with sliders, and the surfaces of the sliders are fixedly connected with connecting blocks, and the tops of the connecting blocks are fixedly connected with springs, and the surfaces of the connecting blocks are fixedly connected with rotating seats, and the other end of the rotating seats is connected to the coating roller;

[0008] A guide scraper is fixedly connected to the surface of the placement table.

[0009] Preferably, the lowest point of the guide scraper is slightly higher than the lowest point of the coating roller.

[0010] Preferably, a recovery box is movably connected to the surface of the placement table.

[0011] Preferably, two groups of connecting rods are fixedly connected to the surface of the placement table, and the other ends of the connecting rods are fixedly connected to the glue box.

[0012] Preferably, the bottom of the inner cavity of the glue box is provided with a slope, and the groove is located at the lowest point of the slope.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The spring in the inner cavity of the sliding groove releases its elasticity at all times to push the sliding block and the connecting block downward. The rotating seat fixedly connected to the surface of the connecting block drives the coating roller downward to maintain pressure on the paper to ensure uniform coating. The lowest point of the guide scraper fixedly connected to the surface of the placement table is slightly higher than the lowest point of the coating roller, and the lowest point of the guide scraper is also slightly higher than the paper surface. When there is too much glue on the paper surface, the guide scraper will scrape off the excess glue on the paper surface. As the glue accumulates, the glue flows into the recovery box.

During the transportation process, the coating roller 2 contacts the paper, and glue is coated on the coating surface of the paper. At the same time, when the coating roller 2 contacts the paper, the spring 12 in the inner cavity of the sliding groove 5 releases its elasticity at all times to push the slider 6 and the connecting block 7 to move downward, and the rotating seat 8 fixedly connected to the surface of the connecting block 7 drives the coating roller 2 to maintain pressure on the paper downward to ensure uniform coating.

[0023] Working principle: Glue flows through the groove 4 along the slope of the inner cavity of the glue box 1, and then drips onto the surface of the coating roller 2 through the groove 4. The surface of the coating roller 2 is coated with glue, and the paper is transported by the conveying table. During the transportation process, the coating roller 2 contacts the paper, and glue is coated on the surface of the paper.
