[0002] Corrugated cardboard boxes are one of the most widely used packaging products, consistently ranking first in usage among all packaging materials. They are considered green and environmentally friendly, facilitating environmental protection and ease of loading, unloading, and transportation. Besides protecting goods and facilitating warehousing and transportation, they also beautify and promote products. Corrugated cardboard boxes often have text or patterns printed on their outer walls, making them increasingly attractive. However, during printing on corrugated cardboard materials, the thickness of the material can cause the printing rollers to not make proper contact with the box. Furthermore, the gaps between the printing rollers are mostly fixed and cannot be adjusted as needed, resulting in reduced printing quality and consequently, decreased usability.

[0019] The drive assembly allows the drive bracket, drive motor, drive rod, and drive gear to work together. The drive motor drives the drive rod and drive gear to rotate. Because the drive gear meshes with its corresponding mounting groove, it causes the mounting J-shaped plate to move downwards along the mounting bracket. Then, the transmission roller between the two mounting J-shaped plates also moves downwards and contacts the material, thus controlling the material thickness through compression. The adjustment assembly allows the movable bracket, movable motor, and movable cam to work together. The movable motor drives the movable cam to rotate, providing a pushing force to the adjusting arc block. The movable assembly allows the adjusting bracket, lower printing roller, adjusting support plate, adjusting arc block, adjusting spring, upper printing roller, and adjusting hose to work together. The adjusting arc block also drives the adjusting support plate and adjusting spring downwards along the adjusting bracket. Then, the adjusting support plate also drives the upper printing roller downwards, controlling the gap between the lower and upper printing rollers. This printing action on the surface of the compressed material allows for adjusting the required material thickness and controlling the gap between the printing rollers, thus improving the performance.

A mounting J-shaped plate 4 is provided through the top of the mounting bracket 2. Mounting blocks and mounting blocks 5 are fixedly connected to both ends of the mounting J-shaped plate 4, respectively. Mounting tooth grooves are opened on the side wall of the mounting J-shaped plate 4. A transmission roller 6 is rotatably connected between the two mounting blocks 5. Driving grooves are opened on both sides of the outer side wall of the mounting bracket 2. A driving assembly for adjusting the movement of the mounting J-shaped plate 4 is connected to the side wall of the mounting bracket 2. The driving assembly includes two driving brackets 7 fixedly connected to the side wall of the mounting bracket 2. A driving motor 8 is fixedly connected to the surface of one of the driving brackets 7. A driving rod 9 is fixedly connected to the output end of the driving motor 8. The end of the driving rod 9 passes through one of the driving brackets 7 and is rotatably connected to the other driving bracket 7. A driving gear 10 is fixedly sleeved on the outer side wall of the driving rod 9. The driving gear 10 meshes with its corresponding mounting tooth groove and drives the driving rod 9 to rotate through the driving motor 8.
[0027] An adjusting bracket 11 is fixedly connected to the top of the receiving bracket 1. A lower printing roller 12 is rotatably connected between the two sides of the inner wall of the adjusting bracket 11. Both ends of the lower printing roller 12 pass through the adjusting bracket 11 and extend to the outside of the adjusting bracket 11. Two adjusting components are provided through the top of the adjusting bracket 11. The adjusting components include adjusting support plates 13 that pass through the top of the adjusting bracket 11. One end of the adjusting support plate 13 is fixedly connected to an adjusting arc block 14. An upper printing roller 16 is rotatably connected between the two adjusting support plates 13. An adjusting spring 15 is movably sleeved on the outer wall of the adjusting support plate 13. The two ends of the adjusting spring 15 are fixedly connected to the side wall of the adjusting arc block 14 and the side wall of the adjusting bracket 11, respectively. One end of the upper printing roller 16 passes through one of the adjusting support plates 13 and is rotatably connected to an adjusting hose 17. The end of the adjusting hose 17 is rotatably connected to one end of the lower printing roller 12. By pushing the adjusting support plate 13 on the adjusting arc block 14 to move downward, the adjusting support plate 13 also drives the upper printing roller 16 to move downward and move closer to the lower printing roller 12.
[0028] Both sides of the outer wall of the adjusting bracket 11 are connected to movable components for adjusting the arc block 14.

[0029] Working principle: In use, the front and rear sides of the receiving bracket 1 are first installed with the external conveyor, so that the material passes between the two mounting rollers 3 and the transmission roller 6. Then, the drive motor 8 is started, which drives the drive rod 9 and the drive gear 10 to rotate. Because the drive gear 10 is engaged with its corresponding mounting groove, it drives the mounting J-shaped plate 4 to move downward along the direction on the mounting bracket 2. Then, the transmission roller 6 between the two mounting J-shaped plates 4 also moves downward, so that the transmission roller 6 comes into contact with the material. Then, the material comes into contact with the two mounting rollers 3 and is squeezed, so as to control the thickness of the material and ensure the squeezing effect.
[0030] Simultaneously, the other end of the lower printing roller 12 is rotatably installed on the pipe of the external material pump. Then, when the extruded material passes between the lower printing roller 12 and the upper printing roller 16, the upper and lower surfaces of the material are printed. Then, the movable motor 19 is started, which drives the movable cam 20 to rotate, so that the movable cam 20 gives a pushing force to the adjusting arc block 14, so that the adjusting arc block 14 also drives the adjusting support plate 13 and the adjusting spring 15 to move downward along the direction on the adjusting bracket 11. Then, the adjusting support plate 13 also drives the upper printing roller 16 to move downward, thereby controlling the gap distance between the printing of the lower printing roller 12 and the upper printing roller 16, thus printing on the surface of the extruded material during transmission and ensuring the effect of adjusting the gap.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
