[0040] Please see Figure 1-4This utility model provides a technical solution: a gravure printing coating machine with good stability, including a cabinet 1, a fixed frame 11 fixedly installed on the cabinet 1, and a conveying mechanism 2 for conveying paper. The conveying mechanism 2 is fixedly installed on the cabinet 1 and the fixed frame 11. The conveying mechanism 2 includes a lifting frame 21. Two hydraulic push rods 211 are fixedly installed on the top wall inside the fixed frame 11. The telescopic ends of the two hydraulic push rods 211 are fixedly connected to the lifting frame 21. Multiple driven rollers 22 are rotatably installed on the lifting frame 21. A mounting frame 23 is fixedly installed on the cabinet 1. Multiple driving rollers 24 are rotatably installed on the mounting frame 23. The mounting frame 23 is located below the lifting frame 21. A second geared motor 25 is fixedly installed on the mounting frame 23. The second geared motor 25 is driven and connected to the multiple driving rollers 24.
[0041] Among them, the two hydraulic push rods 211 drive the lifting frame 21 to move longitudinally through the extension and retraction of the telescopic end, thereby adjusting the height of multiple driven rollers 22. The geared motor 25 can drive multiple active rollers 24 to rotate through multiple transmission belts and transmission sprockets, thereby cooperating with the driven rollers 22 to squeeze paper or paperboard, and using friction to transport paper or paperboard, resulting in higher material conveying efficiency.
[0042] The glue application mechanism 3 includes a fixed frame 31, two fixed frames 31 are fixedly mounted on a fixed frame 11, glue application rollers 32 are rotatably mounted on the two fixed frames 31, a support frame 33 is fixedly mounted on the two fixed frames 31, a drive screw 34 is rotatably mounted on the support frame 33, a sliding nut 341 is threadedly connected to the drive screw 34, a scraper 35 is fixedly mounted on the sliding nut 341, and a drive motor 342 is fixedly mounted on the support frame 33, the drive motor 342 is driven by the drive screw 34.
[0043] In this process, glue is applied by the glue-applying roller 32, and the drive motor 342 drives the drive screw 34 to rotate, which in turn drives the sliding screw nut 341 to move laterally, thereby driving the scraper 35 to move laterally and flatten the glue on the glue-applying roller 32.
[0044] A storage tank 36 is fixedly installed on the upper surface of the fixed frame 11. Multiple nozzles 362 are fixedly installed on the fixed bracket 31. The multiple nozzles 362 are positioned above the coating roller 32. A delivery pump 361 is fixedly installed on the fixed frame 11. One end of the delivery pump 361 is connected to the storage tank 36 through a pipe, and the other end is connected to the multiple nozzles 362.
[0045] Furthermore, the adhesive is stored in the storage tank 36, and the delivery pump 361 delivers the adhesive to the nozzle 362, which then sprays the adhesive onto the coating roller 32.

[0047] Specifically, the drive motor 422 drives the bidirectional threaded rod 42 to rotate, thereby adjusting the position of the two sliders 421. When the bidirectional threaded rod 42 rotates in the forward direction, the two sliders 421 and the two limiting rollers 43 move closer to each other. When the bidirectional threaded rod 42 rotates in the reverse direction, the two sliders 421 and the two limiting rollers 43 move further apart from each other. The two limiting rollers 43 are used to restrict the position of the paper and cardboard to prevent their conveying position from deviating.

[0049] It should be noted that the geared motor 121 drives the output roller 12 to rotate by means of belts, and the output roller 12 conveys the glued paper and cardboard.
[0050] The working principle and usage process of this utility model are as follows: After installation, this utility model is controlled by a corresponding controller. The two hydraulic push rods 211 drive the lifting frame 21 to move longitudinally through the extension and retraction of their telescopic ends, thereby adjusting the height of multiple driven rollers 22. The second reduction motor 25 drives multiple active rollers 24 to rotate through multiple transmission belts and transmission sprockets, which in turn work with the driven rollers 22 to squeeze paper or paperboard. The paper or paperboard is conveyed by friction. The second drive motor 422 drives the bidirectional threaded rod 42 to rotate, thereby adjusting the position of the two sliders 421. The two limit rollers 43 restrict movement. The paper and cardboard are positioned to prevent them from shifting during transport. Glue is stored in a storage tank 36, and a delivery pump 361 delivers the glue to nozzles 362. Multiple nozzles 362 spray the glue onto the coating roller 32, which then applies the glue. A drive motor 342 drives a drive screw 34 to rotate, which in turn drives a sliding nut 341 to move laterally, thereby causing a scraper 35 to move laterally and smooth the glue on the coating roller 32. A reduction motor 121 drives an output roller 12 to rotate via a belt or other means, and the output roller 12 transports the glued paper and cardboard.
[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
