[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Referring to Figures 1-3 , an embodiment provided by the present invention: an aqueous ink printing and die-cutting machine for preventing carton deformation, including a machine body 1, a deformation prevention structure is arranged on the surface of the machine body 1. The deformation prevention structure includes a fixing plate 2. There are two groups of fixing plates 2, and the two groups of fixing plates 2 are symmetrically arranged with the central axis of the machine body 1 as the symmetry axis. The length of the group of fixing plates 2 far from the support plate 19 is longer than that of the group of fixing plates 2 close to the support plate 19. A cross plate 3 is fixedly connected to the top of the fixing plate 2, a cylinder 4 is fixedly connected to the top of the cross plate 3, the output end of the cylinder 4 is fixedly connected to a fixing frame 5, a vacuum pump 6 is fixedly connected to the inside of the fixing frame 5, the output end of the vacuum pump 6 is fixedly connected to a vacuum chuck 7, and the vacuum chuck 7 can adsorb the top end of the flattened carton. A driving component is arranged on the surface of the fixing plate 2, and an inserting component is arranged on the surface of the fixing plate 2.

[0033] Referring to Figures 3-5 , the bottom of the fixing plate 2 is fixedly connected to the upper surface of the machine body 1. The driving component includes a mounting plate 9. The side wall of the mounting plate 9 is fixedly connected to the side wall of the fixing plate 2. A through groove 8 is formed through the surface of the mounting plate 9. An electric push rod 10 is fixedly connected to the bottom of the mounting plate 9. The output end of the electric push rod 10 is fixedly connected to a lifting plate 11. The outer wall of the lifting plate 11 is slidably connected to the inner wall of the through groove 8. An inserting plate 15 is arranged at the bottom of the lifting plate 11. The upper surface of the end of the inserting plate 15 close to the vacuum chuck 7 is arranged in a downward inclined state. The inserting plate 15 can be inserted into the gap of the flattened carton. The inserting component includes a moving groove 12. The moving groove 12 is opened on the lower surface of the lifting plate 11. A moving block 13 is slidably connected to the inner wall of the moving groove 12. A support rod 14 is fixedly connected to the bottom of the moving block 13. One end of the support rod 14 far from the moving block 13 is fixedly connected to the side wall of the inserting plate 15. The surface of the inserting plate 15 is adapted to the inner wall of the through groove 8. A telescopic spring 16 is fixedly connected to the side wall of the moving block 13. The left and right ends of the telescopic spring 16 are respectively sleeved on the outer walls of a fixed electromagnet 17 and a moving electromagnet 18. A moving electromagnet 18 is fixedly connected to the side wall of the moving block 13. A fixed electromagnet 17 is fixedly connected to the inner wall of the moving groove 12. The fixed electromagnet 17 and the moving electromagnet 18 are electromagnets. After being energized, the opposite ends of the fixed electromagnet 17 and the moving electromagnet 18 are mutually repulsive magnets.

[0034] Referring to Figures 1-3, a support plate 19 is fixedly connected to the outer wall of the body 1. A support rod 20 is fixedly connected to the bottom of the support plate 19, and an inclined plate 21 is fixedly connected to the top of the support plate 19. There are two groups of inclined plates 21, and the two groups of inclined plates 21 are equidistantly distributed on both sides of the support plate 19. The end of the inclined plate 21 away from the body 1 is higher than the end of the inclined plate 21 close to the body 1. A rolling shaft 22 is rotatably connected to the inner surface of the inclined plate 21. There are several groups of rolling shafts 22, and the several groups of rolling shafts 22 are equidistantly distributed on the opposite sides of the two groups of inclined plates 21. The setting of the rolling shaft 22 can facilitate the external elastic frame to slide onto the conveyor belt on the body 1 and enter the unfolded carton. A rubber pad 23 is fixedly connected to the side wall of the fixing plate 2, and the rubber pad 23 allows the naturally sliding elastic frame to enter the unfolded carton.

[0035] Working principle: When the cartons are placed in batches, they are usually stacked in a flattened state. The flattened cartons are placed on the conveyor belt of the body 1, ensuring that the openings at both ends of the cartons face the two fixing plates 2. When the flattened cartons are transported below the vacuum suction cups 7, the conveyor belt stops running. The two electric push rods 10 drive the two lifting plates 11 to descend. After the lifting plates 11 drive the insertion plates 15 to descend and approach the surface of the conveyor belt, the fixed electromagnet 17 and the moving electromagnet 18 are energized. After the opposite ends of the two generate repulsive magnetism, the telescopic spring 16 is stretched, driving the moving block 13 to move inside the moving groove 12 until the support rod 14 drives the insertion plate 15 to insert into the flattened carton. After the insertion plate 15 fits against the inner wall of the carton, at the same time, the cylinder 4 is activated. The cylinder 4 drives the fixed frame 5 to descend until the vacuum suction cups 7 contact the surface of the carton. The vacuum pump 6 operates to make the vacuum suction cups 7 adsorb the surface of the carton. The cylinder 4 drives the fixed frame 5 to rise again, and the vacuum suction cups 7 drive the carton to rise. Since the cardboard at the bottom of the carton is fixed by the insertion plate 15, the vacuum suction cups 7 adsorb and lift the cardboard at the top of the carton, causing the carton to change from a flattened state to an unfolded state. The openings at both ends of the carton are also in an unfolded state. At this time, the operator places the external elastic frame on the rolling shaft 22. Since the inclined rolling shaft 22 can drive the elastic frame to fall naturally, it enters the carton through the opening of the carton. Finally, by de-energizing the fixed electromagnet 17 and the moving electromagnet 18, the insertion plate 15 returns to its position. The vacuum pump 6 controls the vacuum suction cups 7 to remove the adsorption of the carton. Finally, the conveyor belt moves to drive the supported cartons into the body 1 for printing and die-cutting. There is no need to manually unfold the cartons and place them in the elastic frames separately, improving the efficiency of carton printing and die-cutting and reducing the deformation of the cartons caused by local stress during the process of entering the body 1.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
