[0043] Working principle:

[0044] When in use, the rotating shaft of the cutting cylinder 4 is inserted through the opening of the herringbone notch of the mounting frame 201 and placed at the bottom of the vertical part of the herringbone notch, and then the electric telescopic rod 203 pushes the moving plate 202 to rise, so that the moving plate 202 pushes the rotating shaft of the cutting cylinder 4 to the top of the inverted herringbone notch, and the first roller 204 and the second roller 205 wrap the rotating shaft of the cutting cylinder 4, and at the same time the two gears 3 are meshed with each other, and then the driving motor 9 drives the auxiliary cylinder 8 to rotate, and the cutting cylinder 4 is driven to rotate through the two meshing gears 3, and then the pushing table 10 continuously transports a single cardboard between the auxiliary cylinder 8 and the cutting cylinder 4 for slotting. When cutting, the cardboard presses the fixed seat 705 and the rotating bar 706 together. After the cutting is completed, under the elastic force of the spring 707, the rotating bar 706 rotates to eject the cut paper strip from the cut paper slot, and the disassembly and installation of the cutting cylinder 4 are the same;

[0045] When adjusting the position of the cutting assembly 7 on the cutting cylinder 4, the first forward and reverse threaded screw 605 is rotated to separate the two extruding blocks 602 from each other. Under the elastic force of the return spring 604, the clamping block 603 is retracted into the inner cavity of the T-block 601, so that the T-block 601 can slide freely along the T-slot of the cutting cylinder 4. After the cutting assembly 7 is moved to a suitable position, the first forward and reverse threaded screw 605 is rotated to make the two extruding blocks 602 approach each other, and the mutually parallel inclined surfaces squeeze the clamping block 603 to move away from the first forward and reverse threaded screw 605, so that the clamping teeth of the clamping block 603 are clamped into the rack 5, and the position of the fixing assembly 6 connected to the cutting assembly 7 is fixed;

[0046] By installing cutting assemblies 7 with different types of circular knives on the cutting cylinder 4 and adjusting the distance between the circular knives, paper troughs or divided cardboards of different sizes are cut. The specific adjustment distance is as follows: at the same time, the two second positive and negative threaded screws 703 of the same cutting assembly 7 are rotated, and the two circular knives of the same cutting assembly 7 are moved closer to or separated from each other.

[0047] It should be noted that the above content only illustrates the technical idea of ​​the utility model and cannot be used to limit the protection scope of the utility model. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model. These improvements and modifications all fall within the protection scope of the claims of the utility model.
