DETAILED DESCRIPTION

[0024] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0025] like Figures 1 to 5As shown, an embodiment of the utility model provides a die-cutting machine which is convenient for adjusting the die-cutting size, comprising a base 1, a frame 2 is fixedly mounted on the top of the base 1, a mounting frame 3 is arranged inside the frame 2, the mounting frame 3 and the frame 2 are connected via a lifting mechanism, a brake motor 4 is fixedly mounted on the mounting frame 3, a rotating shaft 5 is fixedly sleeved on the output shaft of the brake motor 4, a disc 6 is fixedly connected to the other end of the rotating shaft 5, slide plates 7 are slidably connected to both sides of the bottom of the mounting frame 3, a cutting knife 8 is arranged on the slide plate 7, a square hole 9 is opened at the bottom of the slide plate 7, a round block 10 located inside the square hole 9 is fixedly mounted at the bottom of the disc 6, and the outer surface of the round block 10 is slidably connected to the inner wall of the square hole 9.

[0026] By starting the brake motor 4, the rotating shaft 5 can drive the disc 6 to rotate, so that the round block 10 can rotate together. Due to the rotation of the round block 10, the inner wall of the square hole 9 will be squeezed, so that the two slides 7 can move toward or away from each other, thereby adjusting the position of the cutting knife 8.

[0027] Furthermore, the lifting mechanism includes a cylinder 11, which is fixedly mounted on the top of the frame 2, and the telescopic end of the cylinder 11 passes through the frame 2 and is fixedly connected to the top of the mounting frame 3. A round rod 12 is fixedly connected between the base 1 and the frame 2, and the mounting frame 3 is movably sleeved on the outer surface of the round rod 12. By starting the cylinder 11, the staff can push the mounting frame 3 to move downward, so that the cutting knife 8 can move downward, and then the cardboard placed on the base 1 can be die-cut.

[0028] Further, the bottom of the slide plate 7 is rotatably connected with a handle 13, and the cutting knife 8 is movably installed in the handle 13. The bottom of the slide plate 7 is also provided with a top hole 14. The angle of the cutting knife 8 can be adjusted by rotating the handle 13, so that the staff can cut the cardboard into materials of different shapes.

[0029] Furthermore, a block 15 is fixedly mounted on the handle 13, a bolt 16 is threadedly connected to the block 15, and the top of the bolt 16 is threadedly connected to the inside of the top hole 14. After the staff rotates the handle 13 to adjust the angle of the top hole 14, the bolt 16 can be screwed into the top hole 14 at the corresponding position, so that the handle 13 can be limited, thereby ensuring the stability of the cutting knife 8.

[0030] Furthermore, a pin 17 is movably connected to the handle 13, one end of the pin 17 penetrates the cutting knife 8, and the other end of the pin 17 is fixedly connected to a pull handle 18. By pulling the pull handle 18 to pull the pin 17 out of the hole on the cutting knife 8, the limiting effect on the cutting knife 8 can be released, so that the staff can disassemble the cutting knife 8 for maintenance or replacement.

[0031] Furthermore, a spring 19 is movably sleeved on the outer surface of the latch 17, and the two ends of the spring 19 are respectively fixedly connected to the surface of the handle 13 and the pull handle 18. By setting the spring 19 in a stretched state, due to the elastic recovery effect of the spring 19, the pull handle 18 and the latch 17 will tend to move closer to the handle 13, so that the latch 17 can be stably maintained in the hole on the cutting knife 8.

[0032] Furthermore, a guide rod 20 is fixedly mounted on the base 1 , and a pressure plate 21 is movably sleeved on the outer surface of the guide rod 20 .

[0033] Furthermore, a driving motor 22 is fixedly mounted on the bottom of the base 1, and a screw rod 23 is fixedly sleeved on the output shaft of the driving motor 22. The top of the screw rod 23 passes through the base 1, and the screw rod 23 is threadedly connected to the pressing plate 21. The screw rod 23 is rotated by starting the driving motor 22, and the pressing plate 21 is threadedly connected to the screw rod 23, so that the pressing plate 21 can move downward, and then the cardboard placed on the surface of the base 1 can be pressed and fixed, so as to avoid the vibration of the die-cutting machine during operation, which causes the cardboard to be misaligned and causes die-cutting errors.

[0034] When in use, the staff can first place the cardboard on the top of the base 1, and then start the driving motor 22. Due to the operation of the driving motor 22, the screw rod 23 can be rotated. Since the screw rod 23 is threadedly connected to the pressure plate 21, the rotation of the screw rod 23 can make the pressure plate 21 move downward to press the cardboard. When the die-cutting size needs to be adjusted before die-cutting the cardboard, the staff can first start the brake motor 4. Due to the operation of the brake motor 4, the rotating shaft 5 can drive the disc 6 to rotate, so that the round block 10 can rotate together. Due to the rotation of the round block 10, the inner wall of the square hole 9 will be squeezed, so that the two slides 7 can move toward or away from each other, and then the position of the cutting knife 8 is adjusted, so that the distance between the two cutting knives 8 changes, so that the cardboard can be cut into different sizes later. If necessary To adjust the angle of the cutting knife 8, the staff can first unscrew the bolt 16 from the top hole 14, then rotate the handle 13, adjust it to a suitable angle, and then tighten the bolt 16 in the top hole 14 at the corresponding position to fix the handle 13. Then the staff can start the cylinder 11 to move the mounting frame 3 downward, so that the cutting knife 8 can move downward together to die-cut the cardboard. If the cutting knife 8 needs to be maintained or replaced, the staff only needs to pull the handle 18 to drive the latch 17 to move and stretch the spring 19, so that the latch 17 can be pulled out of the hole on the cutting knife 8, thereby releasing the limiting effect on the cutting knife 8, and the staff can take the cutting knife 8 out of the handle 13, thereby realizing the disassembly of the cutting knife 8, which is convenient for the subsequent staff to maintain or replace the cutting knife 8.
