Description

Technical Field

[0001] This utility model relates to the field of corrugated paper processing technology, specifically to a corrugated paper coating device. Background Technology

[0002] Corrugated paper lamination involves bonding and pressing a plastic film coated with adhesive to corrugated paper, creating a paper-plastic composite product. The laminated corrugated paper has a smoother and glossier surface due to the thin, transparent plastic film, which not only improves gloss and durability, extending the lifespan of the corrugated paper, but also provides protection against moisture, water, stains, abrasion, folding, and chemical corrosion. Chinese patented invention CN222554254U discloses a high-efficiency corrugated paper laminating machine, relating to the field of corrugated paper processing technology. The machine includes: a frame with an upper structure for corrugated paper laminating; a housing fixedly installed on the upper part of the frame and having a horizontally penetrating channel along the corrugated paper conveying direction; laminating rollers, all installed inside the housing, arranged vertically downwards in parallel; a cleaning mechanism installed inside the housing and frame, with the cleaning mechanism at the same horizontal height as the laminating rollers; and a guiding mechanism installed on the upper part of the frame. This invention uses the cleaning mechanism to perform a certain degree of cleaning on the corrugated paper during conveying, removing any impurities that may be attached to its surface, preventing impurities from being laminated onto the surface of the corrugated paper and affecting the laminating quality, thus improving the protective processing effect on the corrugated paper.

[0003] However, this device still has some problems. In actual use, the device uses a conveyor belt to transport corrugated paper, but the conveyor belt lacks a tension adjustment structure. During the long-term operation of the laminating machine, the conveyor belt will gradually lose elasticity and increase in length due to continuous friction, stretching, and material aging, causing the conveyor belt to become loose. Once the conveyor belt becomes loose, it is prone to slippage during operation, resulting in ineffective and unstable material feeding. Therefore, we proposed a corrugated paper laminating device to solve the above problems. Utility Model Content

[0013] (III) Beneficial Effects Compared with the prior art, the present invention provides a corrugated paper laminating device, which has the following beneficial effects: This invention utilizes a drive motor to rotate a second gear via a rotating rod. The second gear then rotates a meshing first gear. The first gear, via a lead screw, moves a U-shaped plate downwards, which in turn moves an L-shaped plate downwards. The L-shaped plate slides on a corresponding positioning rod, smoothly driving the adjusting roller. During this movement, the L-shaped plate compresses a corresponding spring, causing the adjusting roller to move downwards. The adjusting roller then presses the conveyor belt body downwards, tightening it and changing its tension. This achieves the desired adjustment. The operation is simple, allowing for quick and easy adjustment of the conveyor belt tension and preventing slippage during transport. Attached Figure Description

[0018] When in use, after prolonged use, if it is necessary to adjust the conveyor belt body 3, start the drive motor 15 to drive the second gear 14 to rotate via the rotating rod 13. The second gear 14 drives the meshing first gear 12 to rotate. The first gear 12 drives the U-shaped plate 11 to move downward via the lead screw 10. The U-shaped plate 11 drives the L-shaped plate 7 to move downward. The L-shaped plate 7 slides on the corresponding positioning rod 17. The L-shaped plate 7 can smoothly drive the adjusting roller 8 to move. During the movement, the L-shaped plate 7 compresses the corresponding spring 18. The L-shaped plate 7 drives the adjusting roller 8 to move downward. The adjusting roller 8 squeezes the conveyor belt body 3 downward, making the conveyor belt body 3 taut. At this time, the tension of the conveyor belt body 3 changes, achieving the purpose of adjustment. The operation is simple and facilitates quick adjustment of the tension of the conveyor belt body 3, preventing the conveyor belt body 3 from slipping during conveying.

[0019] In some embodiments, a drive motor 15 is fixedly connected to the other side of one of the two vertical plates 5, and the other end of the rotating rod 13 is fixedly connected to the output shaft of the drive motor 15.
