[0024] Please see Figure 1-4A cardboard box printing and die-cutting machine includes a conveyor frame 1, a top frame 2, a hydraulic cylinder 3, a mounting base 4, and a die-cutting blade 5. The top side of the conveyor frame 1 is connected to the bottom side of the top frame 2. The top center of the top of the top frame 2 is connected to the top of the hydraulic cylinder 3. The output end of the hydraulic cylinder 3 is connected to the top of the die-cutting blade 5 via the mounting base 4. The machine also includes a reversible motor 6, a threaded rod 7, an internally threaded tube 8, a guide sleeve 9, a slide bar 10, a worktable 11, and a die-cutting groove 12. A transmission belt mechanism is provided on the upper side of the conveyor frame 1. The bottom center of the conveyor frame 1 is connected to the bottom end of the reversible motor 6. The output end of the reversible motor 6 is connected to the bottom end of the threaded rod 7. The outer wall of the threaded rod 7 is screwed to the inner wall of the internally threaded tube 8. The top end of the internally threaded tube 8 is connected to the bottom center of the worktable 11. A die-cutting groove 12 is provided on the top of the worktable 11. The left and right center of the bottom of the worktable 11 are respectively connected to the top of a set of slide bars 10. Each part is connected to the bottom end of a set of guide sleeves 9. The inner wall of the guide sleeve 9 is vertically slidably connected to the outer wall of the slide bar 10 on the same side. The cardboard moves on the top of the conveyor frame 1 through the action of the conveyor belt mechanism. When it reaches the die-cutting position, it stops. The forward and reverse motor 6 runs, causing the threaded rod 7 to rotate. The threaded rod 7 is screwed into the internal threaded tube 8 and is slidably constrained by the two sets of guide sleeves 9 and slide bar 10, so that the worktable 11 moves vertically upward, supporting the cardboard until it is higher than the conveying surface. The threaded rod 7 and the internal threaded tube 8 are self-locked by the thread, so that the height of the worktable 11 is fixed. Under the connection of the top frame 2, the hydraulic cylinder 3 acts on the mounting base 4 to move downward. The die-cutting knife 5 acts on the cardboard to cooperate with the die-cutting groove 12 in the worktable 11 for die-cutting. After completion, the hydraulic cylinder 3 acts on the mounting base 4 to connect the die-cutting knife 5 to reset upward. The forward and reverse motor 6 acts on the worktable 11 to reset downward. The die-cut cardboard falls back to the upper surface of the conveyor belt mechanism to continue to be transported forward.
[0025] The transmission belt mechanism includes a reducer 13, a transmission drive motor 14, rollers 15, belt rollers 16, a thin conveyor belt 17, and a slotted section 18. The upper rear left side of the conveyor frame 1 is connected to the right side of the reducer 13. The output end of the transmission drive motor 14 is connected to the input end of the reducer 13. The output end of the reducer 13 is connected to the left end of the rear roller 15. Two sets of rollers 15 are rotatably arranged at the front and rear ends of the upper inner side of the conveyor frame 1. The outer wall of each set of rollers 15 is connected to the inner wall of a set of belt rollers 16. A set of thin conveyor belts 17 are tensioned and sleeved on the outer walls of the left and right sides of the roller 16, and a set of slots 18 are respectively provided on the left and right sides of the top of the workbench 11. When the conveyor drive motor 14 runs, it can be reduced by the reducer 13, which drives the roller shaft 15 connected to it to rotate, thereby causing the belt roller 16 to rotate. Under the tension of the two sets of thin conveyor belts 17, the roller shaft 15 on the front side is connected to the belt roller 16 to rotate, and the cardboard is placed on the top side of the two sets of thin conveyor belts 17, so that it can move and be transported with the thin conveyor belts 17.
[0026] It also includes a limiting ring frame 19.

[0030] In summary, when a carton printing and die-cutting machine is in use, the drive motor 14 runs, and the reducer 13 speeds up the rotation of the connected roller 15, which in turn rotates the belt roller 16. Under the tension of the two sets of thin conveyor belts 17, the front roller 15 is connected to the belt roller 16 and rotates. The cardboard is placed on the top side of the two sets of thin conveyor belts 17 and can then move and be transported along with the thin conveyor belts 17. The limiting ring 19 can limit the outer side of the thin conveyor belts 17 to prevent them from deviating during the movement. When it reaches the die-cutting position, it stops. The forward and reverse motor 6 runs, causing the threaded rod 7 to rotate. The threaded rod 7 is screwed into the internal threaded tube 8 and is slidably constrained by the two sets of guide sleeves 9 and the slide bar 10, causing the worktable 11 to move vertically upward. The cardboard is raised until it is higher than the conveyor surface. The threaded rod 7 and the internal threaded tube 8 are self-locked to fix the height of the worktable 11. Under the connection of the top frame 2, the hydraulic cylinder 3 acts on the mounting base 4 to move down. The die-cutting knife 5 acts on the cardboard to cooperate with the die-cutting groove 12 in the worktable 11 for die cutting. After completion, the hydraulic cylinder 3 acts on the mounting base 4 to connect the die-cutting knife 5 to reset upward. The forward and reverse motor 6 acts on the worktable 11 to reset downward. The die-cut cardboard falls back to the upper surface of the conveyor belt mechanism to continue to be transported forward. In addition, maintenance operations such as inspection can be carried out on the corresponding structure from the outside to the inside through the maintenance port 20. Oil can be injected into the inner wall of the internal threaded tube 8 through the oil injection nozzle 21 for convenient lubrication. After installing the oil injection cap 22 on the outside of the oil injection nozzle 21, the inside of the oil injection nozzle 21 can be sealed and protected.
