Description

Technical Field

[0001] This utility model relates to the field of die-cutting machine technology, specifically a die-cutting machine with adjustable die-cutting depth. Background Technology

[0002] Die-cutting machines, also known as die-cutting machines, cutting machines, or CNC punching machines, are mainly used for die-cutting (full cut, half cut), creasing, hot stamping, lamination, and automatic waste removal of various non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronic products, mobile phone pads, etc. Die-cutting machines use steel blades, hardware molds, and steel wire (or templates carved from steel plates) to apply a certain pressure through the printing plate to cut printed materials or cardboard into a certain shape.

[0003] In the prior art, a die-cutting machine with adjustable die-cutting depth, authorized by publication number CN216464990U, includes a work frame. A gantry plate is fixedly connected to the top of the work frame. A first vertical groove is opened on both sides of the inner wall of the gantry plate. A hydraulic cylinder is provided at the top of the gantry plate. A vertical rod is provided at the bottom of the hydraulic cylinder. A horizontal plate is provided below the vertical rod. A slider is provided on both sides of the outer wall of the horizontal plate. The first vertical groove is adapted to the slider. A limit ring is fixedly connected to the top of the horizontal plate. The central axis of the limit ring coincides with the central axis of the vertical rod. A first limit rod adapted to the vertical rod is threadedly connected to one side of the limit ring. Circular holes are symmetrically opened inside the horizontal plate. A circular rod is slidably installed inside the circular holes. A blade plate is fixedly installed at the bottom of the circular rod.

[0004] In this device, the blade is fixed to the bottom of the blade plate with bolts. When replacing or installing the blade, it is necessary to manually support the blade on the bottom of the blade plate and align it with the bolt holes. This is inconvenient for installing and replacing the blade, and the blade is quite sharp, which can easily pose a safety risk to workers. In addition, when workers need to change to different sizes of blades, they often have to spend a lot of time to remove and replace the corresponding blade plate, which causes inconvenience to workers' daily work and affects the production efficiency of the device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figure 1 - Figure 4 As shown, this utility model provides a technical solution for a die-cutting machine with adjustable die-cutting depth, including a worktable 1, a gantry plate 2 fixedly connected to the top of the worktable 1, a hydraulic cylinder 3 fixedly connected to the top of the gantry plate 2, a horizontal plate 4 fixedly connected to the bottom output end of the hydraulic cylinder 3, an installation plate 6 provided at the bottom of the horizontal plate 4, a positioning rod 7 provided at the bottom of the installation plate 6, the top end of the positioning rod 7 passing through the installation plate 6 and slidably connected to the installation plate 6, a die 12 provided at the bottom of the positioning rod 7, hook plates 14 provided on both sides of the die 12, and a positioning groove 15 adapted to the bottom end of the positioning rod 7 provided on the top of the die 12.

[0024] A pressure plate 8 is fixedly connected to the outside of the positioning rod 7. The top two sides of the pressure plate 8 are hinged with first connecting rods 9. The two first connecting rods 9 are hinged to push plates 10 at the ends away from the pressure plate 8.

[0025] The top of the mounting plate 6 is threaded with a first threaded rod 11. One end of the first threaded rod 11 is rotatably connected to the push plate 10. The mounting plate 6 has an opening inside that conforms to the movement trajectory of the pressure plate 8 and the two first connecting rods 9.

[0026] The bottom of the mounting plate 6 has movement grooves on both sides. The tops of the two hook plates 14 are slidably connected to the two movement grooves. The bottom of the mounting plate 6 has a mounting groove 16. Two racks 17 are slidably connected inside the mounting groove 16. The bottom of one end of the two racks 17 is fixedly connected to the two hook plates 14. The first gear 18 is rotatably installed inside the mounting groove 16. The opposite side of the two racks 17 is meshed with the first gear 18. When fixing the die dies 12 of different sizes, the worker can pull one of the hook plates 14. The other hook plate 14 moves synchronously under the action of the rack 17 and the first gear 18, so that the center of the die dies 12 hooked by one end of the two hook plates 14 is always directly below the mounting plate 6.

[0027] Both sides of the die 12 are provided with slots 13 that are adapted to the hook plate 14. The hook plate 14 slides in contact with the slots 13, and the die 12 is fixedly installed with a cutting tool at the bottom.

[0028] The horizontal plate 4 has two grooves 19 inside, and each groove 19 is rotatably connected to a second threaded rod 21. Each groove 19 is also slidably connected to two sliders 20. The two ends of the second threaded rods 21 pass through the four sliders 20 and are threadedly connected to them. The bottom of each slider 20 is hinged to a second connecting rod 22, and one end of each second connecting rod 22 is hinged to the top of the mounting plate 6. The worker can rotate the second threaded rods 21 through the pivot 24 to move the two sliders 20 at both ends of the second threaded rods 21 closer to or further away from each other, thereby adjusting the height of the die 12 fixed at the bottom of the mounting plate 6 and thus adjusting the depth of the cutting template.

[0029] The mounting plate 6 is internally connected to a rotating shaft 24. Two second bevel gears 25 are fixedly connected to the outside of the rotating shaft 24. One end of each of the two second threaded rods 21 is fixedly connected to a first bevel gear 23. The two first bevel gears 23 are respectively meshed with the two second bevel gears 25. The four corners of the top of the mounting plate 6 are fixedly connected to second slide rods 26. The top ends of the four second slide rods 26 pass through the horizontal plate 4 and are slidably connected to the horizontal plate 4. The top two sides of the horizontal plate 4 are fixedly connected to first slide rods 5. The top ends of the two first slide rods 5 pass through the gantry plate 2 and are slidably connected to the gantry plate 2.

[0030] A third threaded rod 28 is threadedly connected to one corner of the mounting plate 6. A measuring rod 27 is provided at one end of the third threaded rod 28. A friction groove adapted to the third threaded rod 28 is provided on one side of the measuring rod 27. The measuring rod 27 passes through one corner of the mounting plate 6 and is slidably connected to the mounting plate 6. A pointer 29 is fixedly installed at one corner of the mounting plate 6. A label adapted to the pointer 29 is fixedly connected to one side of the measuring rod 27. When adjusting the die-cutting depth of the device, the worker can observe the height of the cutter through the pointer 29 and the label, which makes it convenient for the worker to quickly adjust the die 12 to the appropriate height.

[0031] It should be noted that this utility model is a die-cutting machine with adjustable die-cutting depth. When installing die-cutting molds 12 of different sizes, the worker can move the hook plate 14 to adjust the distance between the two hook plates 14. The slot 13 at the bottom of the die-cutting mold 12 is aligned with the hook end of the hook plate 14, and the die-cutting mold 12 is placed on the hook between the two hook plates 14. The top of the two hook plates 14 is fixedly connected to a rack 17, and a first gear 18 is meshed between the two racks 17. The first gear 18 causes the other hook plate 14 to move synchronously when one hook plate 14 moves, so that the die-cutting mold 12 placed between the tops of the two hook plates 14 is always directly below the mounting plate 6. The die-cutting mold 12 slides in contact with the slot 13. At this time, the worker can push the die-cutting mold 12 directly below the mounting plate 6 so that the positioning slot 15 is aligned with the bottom of the positioning rod 7, and then turn. The first threaded rod 11 rotates, pushing the first connecting rod 9 through the push plate 10. At this time, the first connecting rod 9 drives the pressure plate 8 and the positioning rod 7 to descend. The bottom of the positioning rod 7 is conical, thus guiding the positioning rod 7 into the positioning groove 15. The positioning rod 7 enters the positioning groove 15 to position the die 12, so that when the device installs die 12 of different sizes, the die 12 is always located at the bottom center of the mounting plate 6. The pressure plate 8 descends and contacts the top of the die 12, thus pressing the die 12 tightly against the top of the two hook plates 14, preventing the die 12 from moving during the die-cutting operation when the mounting plate 6 moves up and down, which would affect the processing quality of the device. By rotating the first threaded rod 11, the worker can fix the die 12 of different sizes, thus facilitating the quick disassembly and replacement of the die 12 and improving the applicability of the device.

[0032] When adjusting the die-cutting depth: the hydraulic cylinder 3 drives the horizontal plate 4 to move to the lowest point of the device. At this time, the worker can rotate the third threaded rod 28 so that one end of the third threaded rod 28 is not in contact with the measuring rod 27. The measuring rod 27 descends so that the bottom of the measuring rod 27 contacts the surface of the worktable 1. At this time, the pointer 29 points to the label number, which is the current height of the die 12. Then the worker can rotate the rotating shaft 24 while observing the pointer 29. The rotating shaft 24 drives the second threaded rod 21 to rotate through the second bevel gear 25 and the first bevel gear 23, so that the sliders 20 connected at both ends of the second threaded rod 21 move closer or further apart. The sliders 20 are connected to the mounting plate 6 through the second connecting rod 22. The second connecting rod 22 moves relative to each other to adjust the height of the mounting plate 6. When the required height is reached, the worker can lift the measuring rod 27 and rotate the third threaded rod 28. One end of the third threaded rod 28 fits into the friction groove to fix the measuring rod 27. The measuring rod 27 allows workers to quickly adjust the working height and cutting depth of the die 12 when changing to different sizes, making it easier for the device to process templates of different thicknesses.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
