[0040] This application can be used in the field of coating technology, or in other fields applicable to this application.

[0041] Example 2: Reference Figure 1 , 2 4. Improvement based on Example 1: A cardboard box color printing and laminating device, which is applied to the field of laminating technology;

[0042] In this embodiment, in a static state, the lowest height of the two first pressing rollers 7 is lower than the lowest height of the coating roller 11.

[0043] In this embodiment, two baffles 3 are fixedly installed on the top of the support frame 1. The two baffles 3 are located on both sides of the conveyor belt 2 respectively. The two baffles 3 are used to ensure that the cartons to be processed can be accurately placed on the conveyor belt 2.

[0044] In this embodiment, two limiting frames 17 are fixedly installed on the top of the support frame 1, and the two limiting frames 17 are located on both sides of the conveyor belt 2. Each of the two limiting frames 17 has a limiting groove 18 inside, and a slider 21 is slidably connected inside each of the two limiting grooves 18. A spring 22 is fixedly installed on the top of each of the two sliders 21, and the other end of each spring 22 is fixedly connected to the top inner wall of the corresponding limiting groove 18. A common movable bracket 20 is provided between the two limiting frames 17, and a second pressing roller 19 is rotatably connected inside the movable bracket 20. The outer wall of the second pressing roller 19 mates with the surface of the conveyor belt 2. The two sides of the movable bracket 20 are fixedly connected to one side of each of the two sliders 21 via connecting shafts. The second pressing roller 19 is located between the positioning assembly and the film coating assembly to ensure that the second pressing roller 19 can continuously press against the conveyor belt 2 to complete the pressing and fixing of the positioned carton.

[0045] However, as is well known to those skilled in the art, the working principles and wiring methods of cylinder 5 and motor 16 are commonplace and are all conventional methods or common knowledge, so they will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0046] The usage process and working principle of this utility model technical solution are as follows:

[0047] In use, the user can start the conveyor belt 2 and the motor 16. The conveyor belt 2 transports the cartons, and the motor 16, after starting, drives two turntables 12 to rotate simultaneously via two synchronous pulleys 15. The user can then place the laminated and folded carton onto the conveyor belt 2 from the end equipped with the baffle 3. The baffle 3 ensures that the carton does not deviate too far from the conveyor belt 2 during placement. As the conveyor belt 2 transports the cartons, they pass over the two turntables 12. The two turntables 12 can be moved to both sides of the carton via multiple abutment rods 13 on their outer walls, allowing for correction of any misaligned cartons. The carton is positioned by a push-pull mechanism; after positioning, the carton will enter below the second pressing roller 19. The second pressing roller 19, under the action of the spring 22, continuously abuts against the surface of the conveyor belt 2, pressing and fixing the carton during transport, preventing it from shifting again during movement, and also preventing movement when the carton comes into contact with the laminating assembly. Then, as the conveyor belt 2 continues to transport the carton, it will move to below the moving plate 6. At this time, the cylinder 5 can push the moving plate 6 downwards, which in turn drives the two first pressing rollers 7 and the laminating roller 11 to move downwards synchronously. The pressure rollers 7 and the laminating rollers 11 are at different heights. The two first pressing rollers 7 will first contact the conveyor belt 2. At this time, the first pressing roller 7 on one side will complete the pressing of the carton until the carton moves below the laminating roller 11. As the moving plate 6 continues to descend, the laminating roller 11 will contact the carton and complete the lamination of the carton. The lamination principle of the laminating roller 11 is the same as that in the patent with publication number CN219856462U. After lamination, the carton will pass through the first pressing roller 7 on the other side with the conveyor belt 2 and be discharged after being pressed flat. When the carton is pressed flat... After adjustment, cylinder 5 can drive moving plate 6 to rise. At this time, the two first pressing rollers 7 and film coating roller 11 can rise synchronously. When film coating roller 11 rises, its uncut film will be tightened by the abutment of the first pressing roller 7 and will contact the cutting blade 28 as it rises. The cutting blade 28 can cut the film. When using it, the user can adjust the height of the cutting blade 28 by sliding the blade bracket 27 in the slide groove 26. After adjustment, just tighten the locking nuts 30 at both ends of the threaded rod 29 to make it fit tightly against the fixed frame 4 to lock and position the cutting blade 28.

[0048] It should be noted that in the description of this specification, descriptions such as "first" and "second" are only used to distinguish the features and do not have any actual order or directional meaning. This application is not limited to this.
