[0033] See also Figure 1-Figure 6 , the utility model provides a technical solution:

[0034] A paper cutting mechanism of a paper cutting machine includes a machine tool 1. Support legs 101 are fixedly connected to both sides of the bottom of the machine tool 1. The support legs 101 provide support for the bottom of the machine tool 1. Two sets of intermittent conveyor belts 2 are installed inside the machine tool 1. The intermittent conveyor belts 2 transport paper stacks. A cutting table 201 is fixedly connected between the intermittent conveyor belts 2 and inside the machine tool 1. A strip cutting groove 2011 is provided on the top of the cutting table 201 and at a position corresponding to a gate knife 303.

[0035] Among them, see Figure 1 , Figure 2 , Figure 4 and Figure 6 A support frame 3 is provided between the two sets of flattening transmission mechanisms and above the cutting table 201. A pair of electric telescopic rods 301 are installed below the support frame 3. A press table 302 is fixedly connected below the electric telescopic rod 301. The electric telescopic rod 301 drives the press table 302 to compact the paper stack. A strip-shaped movable groove 3021 is provided in the middle section of the bottom of the press table 302. A rubber pad 3022 is fixedly connected to the bottom of the press table 302. The rubber pad 3022 enhances the contact stability between the press table 302 and the paper stack. Both sides of the press table 302 are rotatably connected with directional pulleys 3023. Both sides of the inner wall of the support frame 3 and the directional pulleys 3023 are connected to the directional pulleys 3023. A limiting slide groove 3024 is provided at a position corresponding to the pulley 3023, and the press platform 302 is slidably connected to the limiting slide groove 3024 through the directional pulley 3023, so as to improve the smoothness of the lifting and lowering of the press platform 302. A gate knife 303 is provided inside the press platform 302 and above the strip movable groove 3021. Both sides of the gate knife 303 are located on the top of the press platform 302 and are equipped with a driving device 304. When the driving device 304 drives the gate knife 303 to pass through the strip movable groove 3021 to cut the paper stack, the press platform 302 compacts the cutting edge of the paper stack to avoid uneven cutting edge of the paper stack due to wrinkles or throwing up when the gate knife 303 cuts.

[0036] For further information, see Figure 1 , Figure 2 and Figure 5 A finishing mechanism is provided on one side of the top of the machine tool 1, and the finishing mechanism is composed of an adjusting frame 4, a bidirectional threaded rod 401, a rotating motor 4011, a sliding rod 402 and a clamping plate 403. The lower part of the adjusting frame 4 is rotatably connected with the bidirectional threaded rod 401, one end of the bidirectional threaded rod 401 is located on one side of the adjusting frame 4 and is equipped with a rotating motor 4011. The rotating motor 4011 drives the bidirectional threaded rod 401 to rotate, so that the clamping plate 403 moves to clamp and level the paper stack, and sliding rods 402 are fixedly connected on both sides of the bidirectional threaded rod 401 and located below the adjusting frame 4.

[0037] For further information, see Figure 1 , Figure 2 and Figure 5 The clamping plates 403 are provided with two groups, and threaded adjustment holes 4031 are opened at positions corresponding to the clamping plates 403 and the bidirectional threaded rods 401. The threaded adjustment holes 4031 of the two groups of clamping plates 403 have opposite thread directions. The two groups of clamping plates 403 are threadedly connected with the bidirectional threaded rods 401 through the threaded adjustment holes 4031 to move in opposite directions, so as to clamp and level the two sides of the paper stack to avoid unevenness on both sides of the paper stack affecting the quality of the cut products. The clamping plates 403 are provided with through holes 4032 at positions corresponding to the sliding rods 402, and the clamping plates 403 are slidably connected with the sliding rods 402 through the through holes 4032 to improve the stability of the movement of the clamping plates 403.

[0038] For further information, see Figure 1 , Figure 2 and Figure 3 Two sets of flattening transmission mechanisms are provided on one side of the sorting mechanism and at the top of the machine tool 1.

[0040] The working process of the utility model is as follows: first, the paper stack to be cut is placed on the intermittent conveyor belt 2 on the left side, and the rotating motor 4011 drives the bidirectional threaded rod 401 to rotate, so that the two sets of clamping plates 403 are threadedly connected with the bidirectional threaded rod 401 through the threaded adjustment hole 4031 to move in the opposite direction, clamping and leveling the two sides of the paper stack, and the intermittent conveyor belt 2 drives the paper stack to be transmitted, and the left flattening transmission mechanism drives the pressure roller frame 502 to press the paper stack downward through the electric telescopic rod 501, and the flattening roller 5021 flattens the paper stack while assisting the intermittent conveyor belt 2 to transmit the paper stack, so as to avoid wrinkles or curling of the paper stack during transportation. The intermittent conveyor belt 2 transfers the paper stack to the cutting table 201, the electric telescopic rod 1 301 drives the pressing table 302 to compact the paper stack, the driving device 304 drives the gate knife 303 to pass through the bar movable groove 3021 to cut the paper stack, and the pressing table 302 compacts the cutting edge of the paper stack to prevent the paper stack from being unevenly cut due to wrinkles or throwing up when the gate knife 303 cuts, the right intermittent conveyor belt 2 drives the cut paper stack to be transferred, and the right flattening transmission mechanism drives the pressing roller frame 502 to descend through the electric telescopic rod 2 501, so that the flattening roller 5021 flattens and conveys the paper stack to prevent the cut paper stack from being wrinkled or curled during transportation. The entire operation process is simple and convenient. Compared with the existing paper cutting mechanism, the utility model can avoid the problems of uneven cutting edges and curling when cutting the paper stack through design, and improve the quality of the finished product of the paper stack cutting.
