[0014] Beneficial effects

[0015] This invention provides an anti-warping corrugated cardboard die-cutting device with added stress relief blocks. Compared with the prior art, it has the following advantages:

[0016] 1. This anti-warping corrugated cardboard die-cutting device with added unloading blocks allows for the following steps when die-cutting corrugated cardboard: First, the cardboard is placed on the processing table. To prevent the cardboard from tilting and creating an angle between it and the die-cutting blade, a rotating rod is first rotated. This rotation drives the second bevel gear, which in turn drives three first bevel gears and a threaded screw. This adjusts the position of the electric suction cups, enabling them to accommodate cardboard of different sizes and improving the stability of the cardboard's adhesion. Then, a motor rotates the cardboard below, further adjusting the angle between the cardboard and the die-cutting blade to prevent the die-cutting position from shifting, thus improving the die-cutting quality. Furthermore, when other edges of the cardboard need die-cutting, simply continue rotating the motor to allow the die-cutting blade to process different edges, thereby increasing the die-cutting efficiency.

[0017] 2. This anti-warping corrugated cardboard die-cutting device with added unloading blocks, when it is necessary to die-cut corrugated cardboard, activates the first electric push rod, which extends and pushes the mounting plate down. The sponge pad first contacts the corrugated cardboard to prevent the pressure plate from crushing it. As the mounting plate continues to descend, the die-cutting blade contacts and cuts into the corrugated cardboard, and the spring is compressed. Due to the buffering effect of the spring, the pressure plate will slowly press down, effectively preventing the corrugated cardboard from warping on both sides during die-cutting, ensuring that the cardboard remains flat throughout the die-cutting process, thereby improving the die-cutting quality of the corrugated cardboard.

[0024] 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.

[0025] This utility model provides two technical solutions:

[0026] Figures 1-5 The first embodiment is shown: an anti-warping corrugated cardboard die-cutting device with added unloading blocks, including a processing table 1, and a die-cutting component 2 and a moving component 3 respectively provided on the top of the processing table 1;

[0027] The die-cutting assembly 2 includes a mounting plate 25. A die-cutting blade 28 is fixedly mounted on the bottom end of the mounting plate 25. Pressure plates 29 are provided on both sides of the outer wall of the die-cutting blade 28. Two slide rods 26 are fixedly mounted on the top end of the pressure plates 29. Springs 27 are sleeved on the outer walls of the two slide rods 26.

[0028] The moving component 3 includes a mounting frame 32. A motor 33 is fixedly mounted on the bottom of the inner wall of the mounting frame 32. The output end of the motor 33 passes through the bottom of the mounting frame 32 and is fixedly mounted on a circular plate 34. Three sliding grooves 35 are opened at the bottom of the circular plate 34. A second moving slide plate 37 is movably inserted into the inner wall of the sliding grooves 35. An electric suction cup 38 is fixedly mounted on the bottom of the second moving slide plate 37. The electric suction cup 38 is existing technology. When the bottom of the electric suction cup 38 contacts the corrugated cardboard, it can adsorb the corrugated cardboard, thereby facilitating the subsequent movement of the corrugated cardboard.

[0029] The die-cutting assembly 2 also includes a frame 21, which is fixedly installed on the top of the processing table 1. An electric slide rail 22 is provided on the top of the frame 21. A first movable slide plate 23 is provided at the output end of the electric slide rail 22. A first electric push rod 24 is fixedly installed on the top of the first movable slide plate 23. The electric slide rail 22 is existing technology and is usually composed of a lead screw and a power source. It can drive the die-cutting blade 28 below to move, thereby facilitating the die-cutting blade 28 to die-cut the corrugated cardboard.

[0030] The output end of the first electric push rod 24 is fixedly connected to the mounting plate 25. The four slide rods 26 slide through the top of the mounting plate 25. One end of the four springs 27 is fixedly connected to the mounting plate 25, and the other end of the four springs 27 is fixedly connected to the two pressure plates 29 respectively. The bottom ends of the two pressure plates 29 are fixedly installed with sponge pads to prevent the cardboard from being crushed. The horizontal height of the sponge pads is lower than the horizontal height of the die-cutting blade 28. When the die-cutting blade 28 moves downward, the sponge pads first contact the surface of the pressure plates 29. As the die-cutting blade 28 continues to move downward, the die-cutting blade 28 performs die-cutting on the corrugated cardboard, and the springs 27 are compressed. The pressure plates 29 can clamp the corrugated cardboard on both sides of the die-cutting blade 28, thereby preventing the corrugated cardboard from warping during die-cutting. At the same time, a spring 27 with a suitable elastic coefficient is selected to prevent the spring force of the spring 27 from being too large and causing damage to the surface of the corrugated cardboard. The first electric push rod 24 can drive the die-cutting blade 28 to move up and down, thereby performing die-cutting on the corrugated board.

[0031] Figures 1-5 The second embodiment is shown. The main difference from the first embodiment is that the moving component 3 also includes a mounting frame 312, which is fixedly mounted on the top of the processing table 1. A second electric push rod 31 is fixedly mounted on the top of the mounting frame 312. The second electric push rod 31 can drive the electric suction cup 38 to move up and down, so that the electric suction cup 38 can adsorb the corrugated cardboard. When the corrugated cardboard rotates, the second electric push rod 31 can be activated to make the corrugated cardboard rise, preventing the corrugated cardboard from rubbing against the processing table 1 when it rotates. The output end of the second electric push rod 31 is fixedly connected to the mounting frame 32. A circular groove 39 is provided at the bottom end of the circular plate 34.

[0032] The inner walls of the three slides 35 are each rotatably fitted with threaded screws 36. The outer walls of the three threaded screws 36 are respectively threadedly connected to the three second movable slide plates 37. When the threaded screws 36 rotate, they can drive the second movable slide plates 37 to move, thereby changing the distance between the electric suction cups 38. This allows the electric suction cups 38 to be adjusted according to the corrugated cardboard of different sizes, improving the adsorption effect on the corrugated cardboard. One end of the outer wall of each of the three threaded screws 36 penetrates the inner wall of the circular groove 39 and is fixedly installed with a first bevel gear 313.

[0033] The outer walls of the three first bevel gears 313 are meshed with second bevel gears 314. A circular shell 310 is fixedly installed at the bottom end of the circular plate 34. A rotating rod 311 is rotatably installed at the bottom end of the circular shell 310. The top end of the rotating rod 311 passes through the inner wall of the circular shell 310 and is fixedly connected to the second bevel gears 314. When the rotating rod 311 is rotated, it can drive the second bevel gears 314 to rotate. When the second bevel gears 314 rotate, it can drive the three first bevel gears 313 to rotate simultaneously.

[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0035] During operation, when die-cutting corrugated cardboard, the cardboard is first placed on the processing table 1. To prevent the cardboard from tilting and creating an angle between it and the die-cutting blade 28, the rotating rod 311 is rotated first. The rotating rod 311 drives the second bevel gear 314 to rotate, which in turn drives the three first bevel gears 313 and the threaded screw 36 to rotate. This adjusts the position of the electric suction cups 38, allowing them to adapt to corrugated cardboard of different areas and improving the stability of the cardboard being suctioned. Then, the second electric push rod 31 is activated, causing the electric suction cups 38 to move downwards and suction the cardboard. The motor 33 then drives the cardboard below to rotate, adjusting the angle between the cardboard and the die-cutting blade 28 to prevent the die-cutting position from shifting, thus improving the die-cutting quality. Simultaneously, when it is necessary to die-cut the corrugated cardboard... When die-cutting the other sides, simply continue to turn on the motor 33 to rotate the corrugated cardboard, allowing the die-cutting blade 28 to perform die-cutting on different sides of the corrugated cardboard, thereby improving the die-cutting efficiency. After the angle of the corrugated cardboard is adjusted, the position of the die-cutting blade 28 on the corrugated cardboard is adjusted by the electric slide rail 22, and then the first electric push rod 24 is turned on. The first electric push rod 24 extends and pushes the mounting plate 25 down. The sponge pad first contacts the corrugated cardboard to prevent the pressure plate 29 from crushing the corrugated cardboard. As the mounting plate 25 continues to descend, the die-cutting blade 28 contacts and cuts into the corrugated cardboard, and the spring 27 is compressed. Since the spring 27 has a buffering effect, the pressure plate 29 will slowly press down, effectively preventing the two sides of the corrugated cardboard from warping during die-cutting, ensuring that the cardboard remains flat during the die-cutting process, thereby improving the die-cutting quality of the corrugated cardboard.
