[0002] In-line cold foil printing equipment for packaging cartons is a comprehensive machine that integrates printing, cold foil stamping, and automated conveying functions, primarily used for the continuous, automated production of packaging cartons. It is widely used in the production of packaging cartons for industries such as food, pharmaceuticals, cosmetics, and electronics. With increasing market demand and technological advancements, the application range of this equipment will continue to expand.

[0003] By integrating printing, cold foil stamping, and an automated conveying system, this in-line cold foil printing system for packaging cartons automates the entire production process, from feeding, printing, cold foil stamping, to discharging. This system not only improves production efficiency but also ensures stable and consistent product quality.

[0004] When the existing device is in use, cardboards can be stacked together and placed on the inner side of the limiting plate, and then the power motor can be controlled to operate. When the power motor is in operation, the roller shaft can be driven to rotate, and when the roller shaft rotates, the rubber belt loop can be driven to rotate. Under the limiting action of the baffle, the rubber belt loop can drive the bottom cardboard to move horizontally due to friction when it rotates. The cardboard can be conveyed to the inside of the first printing mechanism for printing via the rubber belt loop. However, the current equipment can only perform cold stamping on one side of the cardboard when in use. When double-sided printing is required, the cardboard needs to be manually turned over, which will result in low efficiency of double-sided cold stamping of the cardboard. Utility Model Content

[0027] This specific embodiment is a packaging carton inline cold stamping printing equipment, and its structural diagram is as follows Figure 1-6 As shown, the printing device includes a device support 1, a first printing mechanism 2, and a second printing mechanism 3. The first printing mechanism 2 is mounted on the surface of the device support 1, and a first conveyor belt 4 is installed through the inner side of the first printing mechanism 2. The second printing mechanism 3 is mounted on the surface of the device support 1, and a second conveyor belt 5 is installed through the inner side of the second printing mechanism 3. A roller 6 is rotatably mounted on the inner side of the device support 1, and a power motor 7 is connected to the end of the roller 6. A rubber belt loop 8 is sleeved on the surface of the roller 6. A limit plate 9 is connected to the surface of the device support 1.

[0028] The surface of the equipment support 1 is connected to a bracket 18, and a second bearing 19 is embedded in the side surface of the bracket 18. A rotating rod 20 is connected to the inside of the second bearing 19, and the end of the rotating rod 20 is connected to a center roller 21. A drive motor 22 is installed at the end of the center roller 21, and a sandwich plate 23 is connected to the side surface of the center roller 21. The rotating rod 20 forms a rotating structure through the second bearing 19 and the bracket 18, and the sandwich plates 23 are symmetrically arranged on both sides of the center roller 21.

[0029] Among them, a baffle 10 is provided on the side surface of the limit plate 9, and a limit groove 11 is provided on the surface of the baffle 10. A limit column 12 is passed through the inside of the limit groove 11, and the limit column 12 is connected to the side surface of the limit plate 9. The side surface of the baffle 10 is connected to a connecting block 13, and a threaded hole 14 is provided on the surface of the connecting block 13. A cross bar 15 is connected to the inner wall of the equipment support 1, and a first bearing 16 is embedded in the inner wall of the cross bar 15. A threaded rod 17 is passed through the inside of the first bearing 16.

[0030] In addition, the baffle 10 forms a sliding connection with the limiting column 12 through the limiting groove 11, the threaded rod 17 forms a rotating structure with the cross bar 15 through the first bearing 16, and the threaded rod 17 and the threaded hole 14 are threadedly connected.

[0031] Working principle: When using the device of this technical solution, you can first rotate the threaded rod 17. When the threaded rod 17 rotates, it can drive the connecting block 13 to move longitudinally through the threaded connection relationship with the threaded hole 14. The longitudinal movement of the connecting block 13 can drive the baffle 10 to move longitudinally. The longitudinal movement of the baffle 10 can drive the limiting groove 11 to slide on the surface of the limiting column 12. In this way, the position of the baffle 10 can be adjusted according to the height of the cardboard;

[0032] Next, the cardboards are stacked together and placed on the inner side of the limiting plate 9. Then, the power motor 7 is controlled to operate. When the power motor 7 operates, it can drive the roller shaft 6 to rotate. When the roller shaft 6 rotates, it can drive the rubber belt loop 8 to rotate. Under the limiting action of the baffle 10, the rubber belt loop 8 can drive the bottom layer of cardboard to move horizontally due to friction. In this way, the cardboard can be conveyed to the surface of the first conveyor belt 4. When the first conveyor belt 4 drives the cardboard to move to the inside of the first printing mechanism 2, the first printing mechanism 2 can perform cold stamping on the upper surface of the cardboard.

[0033] Then the first conveyor belt 4 drives the cardboard to continue to move horizontally. When the cardboard is conveyed to the end position of the first conveyor belt 4, the cardboard can be inserted into the interlayer of the interlayer plate 23. At this time, the drive motor 22 can be operated. When the drive motor 22 is running, it can drive the rotating rod 20 to rotate inside the second bearing 19. When the rotating rod 20 rotates, it can drive the center roller 21 to rotate. The rotation of the center roller 21 can drive the interlayer plate 23 to rotate. The rotation of the interlayer plate 23 can drive the cardboard to rotate. When the interlayer plate 23 drives the cardboard to rotate 180°, one side of the cardboard can fall on the surface of the second conveyor belt 5. At this time, the second conveyor belt 5 can convey the cardboard by friction. After the second conveyor belt 5 drives the cardboard to move to the inner side of the second printing mechanism 3, the other side of the cardboard can be cold-stamped by the second printing mechanism 3.

[0034] All technical features in this embodiment can be freely combined according to actual needs.

[0035] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
