[0002] Traditional die-cutting refers to a cutting process used in the post-production of printed materials. This process allows printed materials or other paper products to be cut according to pre-designed patterns using a die-cutting blade, thus expanding the possibilities of printed materials into shapes that are no longer limited to straight edges or right angles. Traditional die-cutting involves using a die-cutting blade, assembled into a die-cutting plate according to the design requirements, and then, under pressure, cutting the printed material or other sheet material into the desired shape or cut.

[0003] Currently, during the die-cutting process, when the position of the die-cutting knife and the die-cutting material below does not correspond or the moving speed of the die-cutting material does not match the cutting speed of the die-cutting knife, it will affect the die-cutting accuracy and the quality of the die-cutting product. Utility Model Content

[0007] With this technical solution, the die-cutting tape passes through the mounting gantry and is ultimately die-cut and wound onto the take-up reel. The die-cutting cylinder is activated to cut the tape as it passes beneath it. If the die-cutting position of the die-cutting tape deviates from the die-cutting blade, a driver adjusts the position of the unwinding and take-up gantry on the baseplate to correct the deviation. Through the coordinated operation of the baseplate, unwinding and take-up gantry, and mounting frame, deviation correction is achieved, improving die-cutting precision.

[0031] The following is combined with Figure 1-4 The present application is further described in detail. The embodiment of the present application provides a die-cutting device with a deviation correction effect, which has the effect of improving the accuracy of the die-cutting process.

[0033] Reference Figure 1 and Figure 2 The unwinding gantry 2 is provided with an unwinding shaft 21 that rotates along the width direction of the base plate 1. The unwinding gantry 2 is provided with an unwinding motor 22, and the output shaft of the unwinding motor 22 is transmission-connected to one end of the unwinding shaft 21. Two unwinding guide rollers 23 are provided on the unwinding gantry 2 to rotate parallel to the unwinding shaft 21.

[0034] Reference Figure 2-4 The mounting gantry 30 is arranged on the top surface of the mounting frame 3, and the flattening assembly 5 is arranged on the side of the mounting frame 3 close to the unwinding gantry 2. The flattening assembly 5 includes a flattening roller 51, a flattening motor 52, and a mounting plate 53. Two flattening rollers 51 are arranged horizontally and symmetrically about the central axis in the longitudinal direction of the mounting frame 3, and the distance between the two flattening rollers 51 gradually increases as they move away from the unwinding gantry 2. Two mounting plates 53 are connected to the mounting gantry 30, and the two mounting plates 53 are arranged in a one-to-one correspondence with the two flattening rollers 51. Two flattening motors 52 are provided on the mounting gantry 30, and the two flattening motors 52 are arranged in a one-to-one correspondence with the two flattening rollers 51. One end of the flattening roller 51 is drivingly connected to the output shaft of the flattening motor 52, and the other end is rotatably connected to the mounting plate 53. The flattening roller 51 is arranged in contact with the top surface of the mounting frame 3.

[0035] Reference Figure 2 and Figure 4The mounting gantry 30 is provided with a die-cutting cylinder 13, and the output shaft of the die-cutting cylinder 13 extends vertically downward and is connected to the die-cutting knife 14. The edge of one side in the width direction of the die-cutting belt 15 is provided with a plurality of connecting holes 151 along the length direction of the die-cutting belt 15, and the connecting holes 151 are arranged at equal intervals. The mounting gantry 30 is connected to a connecting plate 16 on the side where the connecting holes 151 are provided near the die-cutting belt 15, and a controller 17 is provided on the connecting plate 16. Two connecting wires 18 are provided on the controller 17, and the ends of the two connecting wires 18 away from the controller 17 are connected to contact blocks 19. One end of the two contact blocks 19 is fitted and corresponds to the position of the connecting holes 151 on the die-cutting belt 15. The edge of the die-cutting belt 15 is also fitted with the two contact blocks 19. The controller 17 is electrically connected to the die-cutting cylinder 13.

[0036] Reference Figure 3 A clamping plate 20 is vertically mounted on the top surface of the mounting frame 3 along its length. The bottom edge of the clamping plate 20 is aligned with the top surface of the mounting frame 3, and one side of the clamping plate 20 abuts the side of the die-cutting belt 15 away from the connecting plate 16. An adjustment screw 28 and a guide rod 29 are vertically mounted on the side of the clamping plate 20 away from the connecting plate 16. The adjustment screw 28 is threadedly connected to the mounting door 30, and the guide rod 29 extends through the mounting door 30 and slidably engages with it. The guide rod 29 is provided with adjustment scale lines along its length.

[0037] Reference Figure 1-3 During the die-cutting operation, the die-cutting tape 15 passes through two unwinding guide rollers 23 and the tensioning roller 24 between them and is transferred to the mounting frame 3. To adjust the tension of the die-cutting tape 15 made of different materials, the tensioning cylinder 27 drives the second sliding block 9 to slide vertically in the connecting groove 26, while the first sliding block 8 slides in the connecting blind groove 25. This allows the height of the tensioning roller 24 to be adjusted, allowing the structure to adapt to the different materials of the die-cutting tape 15.

[0038] Reference Figure 2-4 The die-cutting strip 15 moves above the mounting frame 3. Driven by the flattening motor 52, the two flattening rollers 51 rotate away from each other, stretching the width of the die-cutting strip 15 outward, reducing the possibility of the width of the strip 15 folding inward. For die-cutting strips 15 of different widths, the adjusting screw 28 is rotated. Driven and guided by the adjusting screw 28 and the guide rod 29, the clamping plate 20 abuts against one side of the width of the die-cutting strip 15, achieving positional guidance for die-cutting strips 15 of varying widths, ensuring that the position of the communication hole 151 always corresponds to the two contact blocks 19.

[0039] Reference Figure 3 and Figure 4When the position of the connecting hole 151 corresponds to the position of the two contact blocks 19, the circuit is connected, and the controller 17 sends a signal to the die-cutting cylinder 13. Under the action of the die-cutting cylinder 13, the die-cutting blade 14 moves downward and cuts the die-cutting strip 15, achieving precise cutting of the raw material. When there is a vertical positional deviation between the position of the die-cutting strip 15 and the position of the die-cutting blade 14, the first cylinder 6 and the second cylinder 7 are activated, driving the unwinding gantry 2 and the winding gantry 4 to move along the length of the base plate 1, thereby adjusting the position of the die-cutting strip 15 on the mounting frame 3. The die-cut die-cutting strip 15 is guided by the winding guide roller 12 and finally reeled on the winding guide roller 12.

[0040] The working principle of a die-cutting device with a corrective effect in the embodiment of the present application is as follows: During the die-cutting operation, the die-cutting tape 15 is conveyed to the mounting frame 3 via two unwinding guide rollers 23 and a tensioning roller 24 located between the two rollers. The tensioning roller 24 is height-adjustable to accommodate the tensioning requirements of the die-cutting tapes 15 made of different materials.

[0041] The two flattening rollers 51 stretch the width of the die-cutting strip 15 outward, reducing the possibility of the strip 15 folding inward. When there is a vertical misalignment between the die-cutting strip 15 and the die-cutting blade 14, the first and second cylinders 6 and 7 are activated, driving the unwinding and rewinding gantry 2 and 4 to move along the length of the base plate 1, thereby adjusting the position of the die-cutting strip 15 on the mounting frame 3.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
