[0002] A continuous die-cutting machine for cartons is a type of machinery specifically designed for die-cutting packaging materials such as cartons and boxes. Die-cutting technology ensures that the size and shape of the cartons meet design requirements by creating precise die-cutting plates. Moreover, die-cutting production is highly efficient. In addition, die-cutting can also achieve personalized customization of cartons. According to the packaging needs of different products, different shapes and sizes of die-cutting plates can be made to die-cut cartons with different requirements.

[0003] However, during the application of die-cutting machines, the cardboard to be die-cut is prone to tilting or deviating during the conveying process, which makes it impossible to be accurately conveyed into the round die for die-cutting. This leads to increased cardboard loss and a lower die-cutting yield, resulting in increased production costs. There is a technical problem that the cardboard to be die-cut cannot be limited and guided from the top, bottom and sides to ensure that it is accurately positioned and conveyed for die-cutting.

There is a speed-regulating motor 10. Bearing seats 9 are provided at the top and bottom of the front ends on both sides of the machine body 1. The two sides of the circular mold roller 2 and the circular pressure roller 5 pass through the interior of the bearing seats 9. One side of the circular pressure roller 5 is connected to the output end of the speed-regulating motor 10. The speed-regulating motor 10 drives the circular pressure roller 5 to rotate. The other side of the circular pressure roller 5 and one side of the circular mold roller 2 are provided with transmission gears 11, and the transmission gears 11 mesh with each other. When the circular pressure roller 5 is driven to rotate, the meshing transmission gears 11 drive the circular mold roller 2 to rotate in the opposite direction, thereby transmitting and conveying the paperboard and performing die-cutting processing on the paperboard.

[0024] As a further implementation of this embodiment, such as Figure 1 , Figure 3 and Figure 4As shown, a guide roller 13 is rotatably connected between the rear ends of the two sides of the machine body 1 near the bottom. The guide roller 13 is horizontally arranged inside the machine body 1, supporting and guiding the cardboard for die-cutting from below. A lifting groove 6 is provided on the inner side of the machine body 1 above the guide roller 13. A stabilizing pressure roller 7 is rotatably connected between the two sides inside the lifting groove 6. The stabilizing pressure roller 7 is parallel to the guide roller 13 and limits the cardboard from above to prevent it from tilting upwards and affecting normal input. Annular limiting plates 14 are provided on both sides of the outside of the guide roller 13. When the cardboard is conveyed between the guide roller 13 and the stabilizing pressure roller 7, the limiting plates 14 limit the sides of the cardboard to ensure accurate orientation. The guide roller 13 is conveyed to the die-cutting mold 3 for die-cutting. The inner side of the limiting plate 14 outside the guide roller 13 is provided with a ring-shaped protective rotating plate 15. The protective rotating plate 15 rotates with the moving cardboard to prevent the cardboard from getting stuck. The outer side of the limiting plate 14 outside the guide roller 13 is provided with a connecting sleeve 18. The two sides of the rear end of the guide roller 13 are provided with fixing screw holes 20. The rear end of the connecting sleeve 18 is inserted with a connecting bolt 19. The fixing screw holes 20 are arranged at equal intervals on both sides of the rear end of the guide roller 13. The front end of the connecting bolt 19 is inserted into the interior of the fixing screw hole 20. The spacing of the limiting plate 14 can be adjusted by connecting the connecting bolt 19 with the fixing screw holes 20 at different positions to accommodate cardboards of different widths that need to be die-cut.

[0025] When in use, adjust the connecting sleeve 18 to a suitable distance according to the width of the cardboard to be die-cut. Then connect the connecting bolt 19 inserted at the rear end of the connecting sleeve 18 to the corresponding fixing screw hole 20 to stabilize the connecting sleeve 18. This will stabilize the limiting plate 14 on both sides outside the guide roller 13. During the conveying process, the cardboard is supported and guided from below by the guide roller 13 at the bottom of the rear end between the two sides inside the machine body 1. At the same time, the stabilizing pressure roller 7 above the guide roller 13 limits the cardboard from above to prevent it from tilting upwards. Meanwhile, the limiting plate 14 limits the cardboard from the side, and the protective rotating plate 15 rotates with the movement of the cardboard to prevent it from getting stuck and damaging the side of the cardboard.

[0026] As a further implementation of this embodiment, such as Figure 1 , Figure 3 and Figure 4As shown, lifting adjustment components are provided at the rear ends of both sides of the top of the machine body 1. The lifting adjustment components include positioning sleeves 12, which are located at the rear ends of both sides of the top of the machine body 1. The bottom end of the positioning sleeves 12 is rotatably connected to the adjusting sleeves 16. Lifting rods 17 are provided on both sides of the top of the lifting groove 6. The top end of the lifting rods 17 passes through the interior of the adjusting sleeves 16 and extends into the interior of the positioning sleeves 12. The lifting groove 6 and the stabilizing pressure roller 7 are positioned inside the machine body 1 by the inserted lifting rods 17 and the positioning sleeves 12. The outer side of the lifting rods 17 is provided with external threads, and the inner side of the adjusting sleeves 16 is provided with internal threads that cooperate with the outer threads of the lifting rods 17. By rotating the adjusting sleeves 16, the lifting rods 17 can be adjusted to lift and lower through the threaded connection, thereby adjusting the distance between the stabilizing pressure roller 7 and the guide roller 13 to accommodate different thicknesses of cardboard.

[0027] When in use, the adjusting sleeve 16 connected to the bottom of the positioning sleeve 12 is rotated according to the thickness of the cardboard. When the adjusting sleeve 16 rotates, it drives the lifting rod 17 that runs through it to rise and fall through the threaded connection. When the lifting rod 17 rises and falls, it drives the lifting groove 6 set between its bottom ends to rise and fall and move inside the rear end of the machine body 1, thereby adjusting the distance between the stabilizing pressure roller 7 and the guide roller 13.

[0028] Working principle: When using the continuous die-cutting machine for cartons, first adjust the connecting sleeve 18 to the appropriate spacing according to the required width of the cardboard to be die-cut. Then connect the connecting bolt 19 to the corresponding fixing screw hole 20 to secure the connecting sleeve 18 and the limiting plate 14. Then, rotate the adjusting sleeve 16 according to the cardboard thickness, which drives the lifting rod 17 through the threaded connection to rise and fall, thereby adjusting the spacing between the stabilizing pressure roller 7 and the guide roller 13. Then, pass the cardboard to be die-cut between the stabilizing pressure roller 7 and the guide roller 13 and between the circular die roller 2 and the circular pressure roller 5, and start the speed regulating motor. 10 drives the circular pressure roller 5 to rotate, and at the same time drives the circular die roller 2 to rotate in the opposite direction through the meshing transmission gear 11. This allows for the transmission and conveying of cardboard and the performance of die-cutting. When the cardboard is conveyed, it is supported and guided from below by the guide roller 13. The stabilizing pressure roller 7 directly above the guide roller 13 limits the cardboard from above to prevent it from warping. At the same time, the limiting plate 14 limits the cardboard from the side, and the protective rotating plate 15 rotates with the movement of the cardboard to prevent jamming and damage to the side of the cardboard. This ensures stable, continuous and precise continuous die-cutting of cardboard.

[0029] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
