[0044] Example 1:

[0045] Please see Figure 1 - Figure 8 As shown, this embodiment provides a clamping device for a die-cutting machine, including:

[0046] A tabletop 1 has a U-shaped frame 2 fixedly installed on its top. Two grooves 17 are formed within the U-shaped frame 2. A bidirectional threaded rod 5 is rotatably installed within each groove 17. A slider 6 is slidably installed within each groove 17 and on the bidirectional threaded rod 5. A connecting rod 7 is rotatably installed on the slider 6. Two pressure plates 9 are provided within the U-shaped frame 2. A groove 10 is formed within each pressure plate 9. A round rod 11 is fixedly installed within each groove 10. Two sliders 12 are slidably installed within each groove 10 and on the round rod 11. One end of the connecting rod 7 is rotatably connected to the corresponding slider 12.

[0047] A drive assembly, located on the U-shaped frame 2, is used to drive the two bidirectional threaded rods 5 to rotate;

[0048] Two through slots 13 are provided, both of which are opened in the U-shaped frame 2 and located between two grooves 17. A movable plate 19 is slidably installed between the two through slots 13, and a die-cutting blade 20 is fixedly installed at the bottom of the movable plate 19.

[0049] A power assembly is located on the U-shaped frame 2 and is used to drive the moving plate 19 to move up and down.

[0050] In this process, the operator can place the cardboard on top of the table 1 and below the two rubber pads 8. Then, the position where the cardboard needs to be cut is adjusted to be directly above the through slot 21, so that the position where the cardboard needs to be cut is on the same horizontal line as the die-cutting blade 20. Then, the operator can hold the cardboard and use the set drive component to drive the two bidirectional threaded rods 5 to rotate. Under the action of the threads, the bidirectional threaded rods 5 will drive the corresponding two sliders 6 to move closer to each other. At this time, the connecting rod 7 on the slider 6 will rotate. When the two connecting rods 7 rotate, they will drive the two sliders 12 to slide on the round rod 11 and move closer to each other. At this time, the pressure plate 9 will move downward until the rubber pad 8 at the bottom of the pressure plate 9 contacts the top of the cardboard. When both rubber pads 8 are in contact with the top of the cardboard, the cardboard is positioned.

One end of each of the two transmission wheels 15 passes through one side of the power chamber 16 and extends into the two grooves 17 respectively. One end of each transmission wheel 15 is coaxially connected to the corresponding bidirectional threaded rod 5.

[0055] Motor 4 is fixedly installed on one side of U-shaped frame 2. The output end of motor 4 extends through one side of U-shaped frame 2 into one of the grooves 17 and is coaxially connected to one of the bidirectional threaded rods 5.

[0056] When the controller starts the motor 4, the output shaft of the motor 4 will drive one of the bidirectional threaded rods 5 to rotate. One of the bidirectional threaded rods 5 will drive one of the transmission wheels 15 to rotate. Subsequently, one of the transmission wheels 15 will drive the belt 14 to rotate. The belt 14 will drive the other transmission wheel 15 to rotate. At this time, the other transmission wheel 15 will drive the other bidirectional threaded rod 5 to rotate, so that both bidirectional threaded rods 5 will rotate.

[0059] In this way, it is ensured that one end of the transmission wheel 15 can rotate within the U-shaped frame 2 and the corresponding groove 17, so that the motor 4 can operate normally.

[0060] Example 4:

[0061] This embodiment provides a clamping device for a die-cutting machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features, wherein the power component includes:

[0062] Two electric push rods 18 are fixedly installed inside the U-shaped frame 2, and both electric push rods 18 are located between two grooves 17. The output ends of both electric push rods 18 are tightly welded to the top of the moving plate 19. A guide rod 3 is fixedly installed in the through groove 13, and one end of the guide rod 3 passes through the moving plate 19.

[0063] In this process, the staff activates two electric push rods 18 through the controller. The output shafts of the two electric push rods 18 will extend and drive the moving plate 19 to move downward. At this time, the two ends of the moving plate 19 will slide downward on the corresponding guide rods 3, making the downward movement of the moving plate 19 more stable.

[0064] Example 5:

[0065] This embodiment provides a pressing device for a die-cutting machine. In addition to the technical solutions of the above embodiments, it also has the following technical features: the moving plate 19 is slidably connected to the guide rod 3.

[0069] Among them, the rubber pad 8 is relatively soft, which can avoid damaging the surface of the cardboard and increase the friction between the pressure plate 9 and the rubber pad 8, ensuring that the die-cutting knife 20 can enter the through groove 21, thereby cutting the cardboard.

[0070] Example 7:

[0071] This embodiment provides a pressing device for a die-cutting machine. In addition to the technical solution of the above embodiment, it also has the following technical features: the slider 6 is threadedly connected to the bidirectional threaded rod 5, the bidirectional threaded rod 5 is provided with two sections of threads with opposite directions of rotation, and the slider 12 is slidably connected to the round rod 11.

[0072] The threaded rod 5 rotates to drive the two sliders 6 to move closer or further apart, ensuring that the slider 12 can slide on the round rod 11.

[0073] Working principle: In use, the operator places the cardboard on top of the table 1, below the two rubber pads 8. Then, the position of the cardboard to be cut is adjusted to be directly above the through slot 21, so that the cutting position is on the same horizontal line as the die-cutting blade 20. The operator then holds the cardboard and starts the motor 4 via the controller. The output shaft of the motor 4 will drive one of the bidirectional threaded rods 5 to rotate, which in turn drives one of the drive wheels 15. Subsequently, the drive wheel 15 drives the belt 14. This will drive another transmission wheel 15 to rotate. At this time, the other transmission wheel 15 will drive another double-threaded rod 5 to rotate, so that both double-threaded rods 5 will rotate. Under the action of the threads, the double-threaded rods 5 will drive the corresponding two sliders 1 6 to move closer to each other. At this time, the connecting rod 7 on the slider 1 6 will rotate. When the two connecting rods 7 rotate, they will drive the two sliders 2 12 to slide on the round rod 11 and move closer to each other. At this time, the pressure plate 9 will move downward until the rubber pad 8 at the bottom of the pressure plate 9 contacts the top of the cardboard. When both rubber pads 8 are in contact with the top of the cardboard, the cardboard is positioned.

[0074] Subsequently, the staff activates the two electric push rods 18 through the controller. The output shafts of the two electric push rods 18 will extend and drive the moving plate 19 to move downward. At this time, the two ends of the moving plate 19 will slide downward on the corresponding guide rods 3, making the downward movement of the moving plate 19 more stable until the die-cutting blade 20 contacts the cardboard and cuts the cardboard. At this time, the die-cutting blade 20 will enter the through groove 21 to ensure that the cardboard can remain stable when cutting the cardboard and avoid the cardboard from shifting.
