[0022] The paper feeding mechanism 300 includes: a transmission frame 310, a suction cup 320, an air pipe 330, a vacuum generator 340, a driving motor 350, a driving wheel 360, a transmission belt 370, a driven wheel 380, a rotating shaft 390, a paper feeding roller group 3100 and a conveyor belt 3200. The transmission frame 310 is connected to the upper part of the workbench 200, the suction cup 320 is connected to both sides of the transmission frame 310, and the suction cup 320 is connected to the vacuum generator through the air pipe 330. 340 is connected, the vacuum generator 340 is connected to the bottom of the workbench 200, the driving motor 350 is connected to the side of the transmission frame 310, the driving wheel 360 is connected to the driving motor 350, the driven wheel 380 is connected to the driving wheel 360 through the transmission belt 370, the driven wheel 380 is connected to the paper feeding roller group 3100 through the rotating shaft 390, the paper feeding roller group 3100 is connected to the transmission frame 310, and the conveyor belt 3200 is connected to the paper feeding roller group 3100.

[0023] The cutting mechanism 500 includes a tool holder 510 , a suspension rod 520 , an upper cutter 530 and a lower cutter 540 . The tool holder 510 is connected to the gantry 100 , the upper cutter 530 is connected to the tool holder 510 via the suspension rod 520 , and the lower cutter 540 is connected to the workbench 200 .

[0024] The paper pressing mechanism 400 includes: a paper pressing device 410, a paper pressing rod 420, a connecting rod 430 and a spring reset device 440. The paper pressing device 410 and the connecting rod 430 are connected to the paper pressing rod 420. The paper pressing device 410 is connected to the gantry 100 through the connecting rod 430. The spring reset device 440 is connected to the upper part of the paper pressing device 410, and the spring reset device 440 is connected to the gantry 100.

[0025] The principle of the utility model is that a lifting paper supply table is arranged at the front side of the paper cutter, and the paper supply table is docked with the transmission frame 310 on the workbench 200. The employee selects the working mode on the control display screen 700 and inputs the cutting parameters. Then the vacuum generator 340 is started. When the vacuum generator 340 is working, the air pipe 330 is used to suck the suction cup 320 and the outside air, so that a vacuum environment is formed in the suction cup 320. The paper is positioned and adsorbed on the conveyor belt 320 through the suction cup 320. The driving motor 350 runs to control the rotation of the driving wheel 360. The driving wheel 360 rotates the driven wheel 380 through the transmission belt 370. The driven wheel 380 drives the rotating shaft 390 and the paper feeding roller group 3100 to run. The paper feeding roller group 3100 and the conveyor belt 3200 transport the paper to the designated cutting line. The hydraulic system 600 first controls the operation of the paper pressing mechanism 400. The paper pressing device 410 directly contacts the paper and presses the paper to prevent it from moving during the cutting process. The paper pressing rod 420 connects the paper pressing device 410 and the connecting rod 430 to transmit power so that the paper pressing device 410 can move up and down. The connecting rod 430 serves as an intermediary for power transmission. After the paper pressing device 410 completes the pressing action, the hydraulic system 600 controls the cutting mechanism 500. The knife holder 510 is fixed on the gantry 100 to provide a stable cutting platform. The suspension rod 520 is controlled to move by the hydraulic system 600. After the paper is in place, the upper cutter 530 is responsible for moving downward for cutting. The lower cutter 540 cooperates with the upper cutter 530. After the cutting is completed, the upper cutter 530 will return to its original position along the suspension rod 520 to prepare for the next cutting. Finally, the spring return device 440 is responsible for pulling the paper pressing device 410 back to its original position to prepare for the next pressing action.

[0026] Compared with the traditional technology, the utility model adds a vacuum suction cup structure for transmitting paper, which can automatically position and absorb the paper to be cut, and transfer it to the paper feeding mechanism to the cutting position. There is no need for employees to manually align the paper and place it on the paper cutting workbench, which avoids the danger of the cutting knife and can also improve the accuracy of paper cutting.

[0027] The specific implementation modes of the present invention are described above, but the present invention is not limited thereto. The present invention can also have various changes without departing from the purpose of the present invention.
