[0020] Please see Figure 1 , Figure 3The creasing mechanism 2 includes a slide plate 21, which is slidably connected to the inside of the frame 1. A screw 22 is threadedly connected to the inside of the slide plate 21, and the screw 22 is connected to the frame 1 via a bearing. A slide rod 23 is welded to the inside of the frame 1, and the slide rod 23 is slidably connected to the slide plate 21. A cylinder 24 is fixedly installed at the upper middle part of the slide plate 21. The cylinder rod of the cylinder 24 passes through the slide plate 21 and is slidably connected to the slide plate 21. A pressure strip 25 is welded to the lower end of the cylinder rod of the cylinder 24. A support strip 26 is slidably connected to the bottom inner side of the frame 1. A guide rod 27 is welded to the upper end of the support strip 26, and the guide rod 27 is slidably connected to the pressure strip 25. By setting the guide rod 27, the movement of the pressure strip 25 is guided. By rotating the screw 22 and the slide plate 21 to make threaded movement, the slide plate 21 drives the cylinder 24 to move. The cylinder 24 drives the pressure strip 25 to move and cooperate with the support strip 26, so that the cardboard can be easily creasing at any position.

[0021] Please see Figure 1 , Figure 4 The adjustment mechanism 3 includes a motor 31. The motor 31 is fixedly installed in the middle of the lower end of the frame 1. The rotating shaft of the motor 31 passes through the frame 1 and is slidably connected to the frame 1. The rotating shaft of the motor 31 is fixedly connected to the support plate 4. A slide cylinder 32 is welded to the lower end of the support plate 4. A top block 33 is slidably connected inside the slide cylinder 32. The top block 33 is slidably connected to the frame 1. A compression spring 34 is provided inside the slide cylinder 32. One end of the compression spring 34 is fixedly connected to the top block 33, and the other end of the compression spring 34 is fixedly connected to the support plate 4. A support 35 is fixedly connected to the bottom inner side of the frame 1. The support 35 contacts the support plate 4. The motor 31 drives the support plate 4 to rotate, thereby changing the position of the cardboard. This makes it easier to perform indentation operations on multiple positions when operating the cardboard. Furthermore, the compression spring 34 acts on the top block 33, making the cardboard accurately positioned after adjustment.

[0022] The specific implementation process of this utility model is as follows: In use, manually move the sliding sleeve 6 upward to disengage the pressure plate 7 from the support plate 4, thereby compressing the spring 8. Then, place the cardboard on the support plate 4, release the sliding sleeve 6, and the spring 8 returns to its original position, causing the pressure plate 7 to be elastically pressed down, thus pressing the cardboard tightly onto the support plate 4. Then, adjust the screw 22 according to the position where the cardboard needs to be pleated. The screw 22 rotates and the sliding plate 21 makes a threaded movement, thereby causing the sliding plate 21 to drive the cylinder 24 to move. Then, start the cylinder 24, which drives the cylinder rod to extend, and the cylinder rod drives the pressure strip 25 to move downward. The pressure strip 25 and the support strip 26 work together to press the cardboard to form an indentation. After the indentation is completed, the motor 31 is started. The motor 31 drives the tray 4 to rotate, thereby changing the position of the cardboard. This makes it easier to perform indentation operations on multiple positions during cardboard operation. The rotation of the tray 4 causes the slide cylinder 32 to drive the top block 33 to change position, thereby causing the top block 33 and the slot of the frame 1 to misalign. This causes the compression spring 34 to be compressed until the station change is completed. Then the motor 31 stops, and the compression spring 34 resets, causing the top block 33 to enter the slot of the current position and limit the tray 4, so that the cardboard is accurately positioned after adjustment.
