In the paper splitting machine in the prior art, in the process of conveying the split paper to the stacking platform 190, the front end of the split paper is easy to curl, so that the paper is easy to fold when reaching the stacking platform 190, the volume of stacking is increased, if the front end of the paper is not greatly influenced when being bent upwards, the upward bent part can automatically restore to be smooth under the action of gravity, if the front end of the paper is bent downwards, the front end of the paper is folded, the flatness of subsequent stacking is influenced, and the overall stacking quality is poor.

Specifically, the conveying assembly in the embodiment of the present invention includes a conveying plate 200 and two rotating rollers 210, as shown in fig. 2 and 3, the conveying plate 200 is fixedly connected with the upper slitting knife 130, when the upper slitting knife 130 moves upward, the conveying plate 200 is synchronously driven to move upward, when the upper slitting knife 130 moves downward, the conveying plate 200 is synchronously driven to move downward, the two rotating rollers 210 are rotatably disposed on the conveying plate 200, one ends of the two rotating rollers 210 close to each other are rotatably connected in the middle position of the conveying plate 200, one ends of the two rotating rollers 210 far away from each other are rotatably connected at two ends of the conveying plate 200, the horizontal position of the two rotating rollers 210 close to each other is lower than the horizontal position of the two rotating rollers 210 far away from each other, so that a V-shaped groove is formed on the vertical surface by the two rotating rollers 210 (the rotation direction is consistent with the conveying direction at this time), when the slit paper falls on the two rotating rollers 210, the lower surface of the two rotating rollers 210 is contacted with the two rotating rollers under the action of gravity, and the two bending ends of the two rotating rollers are not bent, and the paper is not bent, thereby the paper is conveyed in the state before the two bending state is formed, and the paper is folded.
It should be noted that, when the upper cutter 130 moves downward to approach the lower cutter 140, the highest horizontal position of the end of the conveying plate 200 where the two rotating rollers 210 are far away from each other is parallel to the highest horizontal position of the lower cutter 140, so that the paper is in a horizontal state when being cut, and the cutting position of the paper 300 to be cut and the highest position of the two rotating rollers 210 are not staggered, and if the cutting position and the highest position are staggered, the uneven condition of the paper 300 to be cut is caused.
It should be further noted that, in the paper splitting machine in the prior art, in the process of conveying the paper after splitting, paper wrinkles still occur, in order to avoid paper wrinkles occurring in the conveying process, the two rotating rollers 210 are inclined in the conveying direction of the paper, so that one end of the two rotating rollers 210 close to each other is located at the front side in the conveying direction of the paper, and one end of the two rotating rollers 210 far away from each other is located at the rear side in the conveying direction of the paper, so that the two rotating rollers 210 also form a V-shaped groove on a horizontal plane, and the opening faces the opposite direction of the conveying direction of the paper, and when the two rotating rollers 210 rotate, a flattening acting force is given to the paper.
It can be appreciated that since the two rotating rollers 210 form V-shaped grooves on the horizontal plane, a component force is imparted to the two sides of the paper away from each other when the two rotating rollers 210 rotate, and the component force can flatten the wrinkles on the paper or prevent the paper from forming wrinkles during the conveying process, so that the paper is conveyed to the stacking platform 190 without forming wrinkles.

The specific working process of the modularly-designed paper splitting machine provided by the invention is described by combining the above embodiments:
the paper 300 to be slit wound on the unreeling roller 110 sequentially passes through the conveying rollers 120, the tensioning rollers 170 and the flattening rollers 150, passes through a gap between the flattening plate 160 and the frame 100, starts a power source (not shown in the figure), drives the two flattening rollers 150 to rotate around the axes of the two flattening rollers 150, pulls the paper 300 to be slit, pulls the unreeling roller 110 to rotate, thereby starting to continuously convey the paper 300 to be slit, and starts two driving motors 220, the two driving motors 220 drive the two rotating rollers 210 to rotate around the axes of the two rotating rollers through the transmission wheels 230 and the two first universal joints 240, and adjusts the reciprocating frequency of the upper slitting knife 130, so that the conveying length of the paper 300 to be slit is the required length when the upper slitting knife 130 moves downwards to the lower slitting knife 140, and the upper slitting knife 130 continues to move downwards to contact the paper 300 to be slit.
The paper 300 to be cut is flattened to two sides under the action of the two sections of spiral bulges 151 on the periphery of the upper flattening roller 150, so that the paper 300 to be cut is prevented from being wrinkled in the direction perpendicular to the conveying direction, as shown in fig. 3, when the upper slitting knife 130 moves downwards, the conveying plate 200 is driven to move downwards synchronously, at the moment, the right side of the paper 300 to be cut can move downwards to be parallel to the left side synchronously under the action of gravity with the conveying plate 200, at the moment, the left side of the paper 300 to be cut is supported by the flattening plate 160 and the frame 100, so that the cutting edge of the paper is smoother during cutting, and the cutting quality of the paper is improved.
When the paper 300 to be slit is slit by the upper slitting knife 130 and the lower slitting knife 140, the slit paper is conveyed by the two rotating rollers 210 rotating around the axes of the two rotating rollers 210, so as to move towards the stacking platform 190, when the rotating rollers 210 convey the slit paper, the two rotating rollers 210 form a state that two sides of the slit paper are bent upwards on the two rotating rollers 210 due to the inclined arrangement of the two rotating rollers 210, so that the front end of the slit paper cannot be bent upwards and downwards in the conveying process, and under the action of different diameters and smooth curved surfaces of the two rotating rollers 210, the linear speeds of the peripheries of the two rotating rollers 210 at the middle position and the two side positions of the paper are different, so that the slit paper can be acted towards two sides, and the difference of the linear speeds is formed between the different positions of the peripheries of the rotating rollers 210, so that the fine wrinkles can be flattened, the relative friction between the slit paper and the two rotating rollers 210 in the conveying process is reduced, and the lower surface of the slit paper is prevented from being worn. When in conveying, the paper passing over the two rotating rollers 210 is separated from the restriction of the two rotating rollers 210, so that the bending degree of the front end is smaller than that of the rear end, and the buoyancy force received by the front end of the paper is larger than that of the rear side, thereby reducing the inclination degree of the front end of the paper downwards under the action of gravity and improving the conveying distance of the paper.
