Detailed Implementation

[0043] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0044] like Figures 1-4 As shown in the figure, this embodiment proposes a printing device for preventing paper deformation in a packaging printing machine, including: a frame 1, a pressure plate 2, heating tubes 3, a conveyor belt 4, a flattening mechanism, a conveying mechanism, and a suction mechanism. The pressure plate 2 is located inside the frame 1. Multiple heating tubes 3 are provided and are installed on the pressure plate 2. The conveyor belt 4 is located below the pressure plate 2 and has many ventilation holes. Through the cooperation between the frame 1, the pressure plate 2, the conveyor belt 4, the flattening mechanism, the conveying mechanism, and the suction mechanism, the paper can be quickly flattened before entering the printing machine, effectively preventing pattern deformation or loss caused by paper deformation and improving the printing effect.

[0045] The flattening mechanism is located within the frame 1 and is used to drive the pressure plate 2 to flatten the paper. The flattening mechanism includes: slide rods 5, slide plates 6, connecting frames 7, fixed frames 8, a moving assembly, and a lifting assembly. Two slide rods 5 are provided, both slidably connected within the frame 1. The slide plate 6 is slidably connected between the two slide rods 5. The connecting frame 7 is fixedly connected to the bottom end of the slide plate 6. The pressure plate 2 is fixedly connected to the bottom end of the connecting frame 7. The fixed frame 8 is fixedly connected within the frame 1. The moving assembly is located on the fixed frame 8 and is used to drive the slide plate 6 to move. Two lifting assemblies are provided, both located within the frame 1, and are used to drive the slide plate 6 to move up and down. The moving assembly includes: a slide box 9, a drive frame 10, and a first motor 11. The slide box 9 is fixedly connected to the top of the slide plate 6. The top end of the drive frame 10 is rotatably connected to the bottom end of the fixed frame 8, and the bottom end of the drive frame 10 is rotatably and slidably connected within the slide box 9. The first motor 11 is mounted on the fixed frame 8. The output end passes through the fixed frame 8 and is fixedly connected to the top of the drive frame 10. The lifting assembly includes: a guide rod 12, a connecting plate 13, and a first electric cylinder 14. One end of each of the two slide rods 5 is slidably connected to the guide rod 12. Both guide rods 12 are fixedly connected inside the frame 1. The connecting plate 13 is fixedly connected between the two guide rods 12. The first electric cylinder 14 is installed inside the frame 1. The output end of the first electric cylinder 14 is fixedly connected to the connecting plate 13. Specifically, the first electric cylinder 14 drives the connecting plate 13 and the two slide rods 5 to descend. When the slide rods 5 descend, they slide on the guide rod 12, thereby driving the slide plate 6 and the pressure plate 2 to press down. Then, the pressure plate 2 presses the paper. After that, the pressure plate 2 is heated by the heating tube 3 set on the pressure plate 2. Then, the first motor 11 set on the fixed frame 8 drives the drive frame 10 to rotate. When the drive frame 10 rotates, it drives the slide box 9 and the slide plate 6 to slide repeatedly on the slide rods 5, thereby driving the pressure plate 2 to iron the paper flat.

[0046] The conveying mechanism is located inside the frame 1 and is used to convey paper. The conveying mechanism includes a conveying shaft 15 and a second motor 16. There are two conveying shafts 15, both of which are rotatably connected inside the frame 1. The conveyor belt 4 is driven between the two conveying shafts 15. The second motor 16 is mounted on the frame 1, and the output end of the second motor 16 passes through the frame 1 and is fixedly connected to one of the conveying shafts 15. Specifically, the second motor 16 on the frame 1 drives the conveying shafts 15 to rotate, and the conveyor belt 4 drives the paper between the two conveying shafts 15.

[0047] The suction mechanism is installed inside the frame 1 and is used to adsorb the paper onto the surface of the conveyor belt 4. The suction mechanism includes a suction box 17, a suction pipe frame 18, a suction barrel 19, and a fan 20. The suction box 17 is fixedly connected inside the frame 1, and the top of the suction box 17 is in contact with the conveyor belt 4. The top of the suction pipe frame 18 is connected to the suction box 17, and the suction barrel 19 is connected to the bottom of the suction pipe frame 18. The fan 20 is installed inside the suction barrel 19, and the output end of the fan 20 faces the bottom of the suction barrel 19. Specifically, the fan 20 blows air out of the suction barrel 19, thereby creating a negative pressure inside the suction pipe frame 18 and the suction box 17, which in turn drives the paper to be stably adsorbed onto the conveyor belt 4 through the ventilation holes opened on the conveyor belt 4.

[0048] In this embodiment, when the paper needs to be ironed, the paper is placed on the conveyor belt 4. The second motor 16 on the frame 1 drives the conveyor shaft 15 to rotate. The conveyor belt 4 transmits power between the two conveyor shafts 15, thereby conveying the paper. Then, the fan 20 blows air out of the suction tube 19, thereby creating negative pressure in the suction tube frame 18 and the suction box 17. This causes the paper to be stably adsorbed onto the conveyor belt 4 through the ventilation holes. Then, the first electric cylinder 14 drives the connecting plate 13 and the two slide rods 5 to descend. When the slide rods 5 descend, they slide on the guide rod 12, thereby driving the slide plate 6 and the pressure plate 2 to press down. The pressure plate 2 then presses the paper. The heating tube 3 on the pressure plate 2 heats the pressure plate 2. Then, the first motor 11 on the fixed frame 8 drives the drive frame 10 to rotate. When the drive frame 10 rotates, it causes the slide box 9 and the slide plate 6 to slide back and forth on the slide rods 5, thereby driving the pressure plate 2 to iron the paper.

[0049] It should also be noted that the top of the suction box 17, like the conveyor belt 4, has multiple ventilation openings, which are opposite to the ventilation holes on the conveyor belt 4, so that the paper can be adsorbed onto the conveyor belt 4 and the conveyor belt 4 can be stably supported by the pressure of the pressure plate 2.

[0050] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
