[0028] Example 1: Figures 1-7As shown, when cutting a stack of paper, the paper is placed on the workbench 1. The workbench 1 is relatively smooth and convenient for moving the paper. Then the paper is positioned. After the cutting position is determined, the multi-stage hydraulic cylinder 102 is started to drive the movable plate 103 to move downward, so that the cutting knife 105 can be driven downward to cut the paper. During the downward movement of the movable plate 103, the positioning bar 107 can first contact the paper. Then the movable plate 103 moves downward to make the sliding rod 106 slide on the movable plate 103 and stretch the support spring 108, so that the positioning bar 107 can be moved downward to make the cutting knife 105 move downward to cut the paper. The strip 107 can position the paper to avoid wrinkles on the paper. When the movable plate 103 moves, it can drive the movable rod 109 to slide. After the paper is cut, under the action of the cutter 105, the cut paper is in a skewed state. Then the movable plate 103 can be reset. After the movable plate 103 is reset, the movable plate 103 continues to move up.

After the U-shaped frame 201 moves, it can drive the movable rod 206 to move, so that the ball 216 on the support plate 215 abuts against the bevel on the push block 222. The U-shaped frame 201 continues to move, and under the action of the push block 222, the two movable rods 206 can be moved closer to each other, so that the two push plates 210 can be moved closer to each other. The push plates 210 can push the two sides of the cut paper pile, and the cut paper pile can be neatly arranged. The movement of the U-shaped frame 201 can push the cut paper piles, and under the action of the U-shaped frame 201 and the remaining paper piles, the other two sides of the cut paper piles can be aligned, so that it is convenient to align the four sides of the cut paper piles after cutting the paper, and then reset and move the movable plate 103 downward to reset the U-shaped frame 201 to complete the alignment of the paper piles, so that it is convenient to align the cut paper piles after cutting, avoid skewness or misalignment of edges of stacks of paper, and facilitate subsequent processing operations of the paper.

[0030] Example 2: Figure 4 and Figure 8As shown, when the paper piles are tidy, the U-shaped frame 201 moves, and the movement of the U-shaped frame 201 drives the tidying plate 233 to move. After the tidying plate 233 moves, the movable block 236 slides on the oblique edge of the triangular plate 237, so that after the U-shaped frame 201 moves, the tidying plate 233 moves downward under the action of gravity, so that the tidying plate 233 can block the through groove on the U-shaped frame 201. The subsequent movement of the U-shaped frame 201 can tidy the paper piles through the tidying plate 233. After tidying, the U-shaped frame 201 is reset, so that the tidying plate The movable block 236 on 233 moves upward under the action of the hypotenuse of the triangle plate 237, so that the aligning plate 233 moves upward, and then after the U-shaped frame 201 is reset, the aligning plate 233 no longer blocks the through slot on the U-shaped frame 201. At this time, the staff can remove the cut paper pile horizontally through the through slot on the U-shaped frame 201, which is convenient for subsequent processing. After the cut paper is aligned, it is also convenient to remove the cut paper, avoiding the cut paper being blocked and difficult to remove, thereby improving the convenience of paper processing.

After determining the cutting position, the multi-stage hydraulic cylinder 102 is started to drive the movable plate 103 to move downward, so that the cutting knife 105 can be driven to move downward to cut the paper. During the downward movement of the movable plate 103, the positioning bar 107 can first contact the paper. Then the movable plate 103 moves downward so that the sliding rod 106 slides on the movable plate 103 and stretches the supporting spring 108, so that the positioning bar 107 can position the paper to avoid wrinkles in the paper. While the movable plate 103 moves, it can drive the moving rod 109 to slide upward. After the paper is cut, under the action of the cutting knife 105, the cut paper pile is in a skewed state. Then the movable plate 103 can be reset. After the movable plate 103 is reset, the movable plate 103 continues to move upward. At this time, the limit block 1 The U-shaped frame 201 is moved so that the fixed rod 202 slides on the support rod 204 and stretches the return spring 205. After the U-shaped frame 201 moves, it can drive the movable rod 206 to move, so that the ball 216 on the support plate 215 abuts against the bevel edge of the push block 222, and the U-shaped frame 201 continues to move. Under the action of the push block 222, the two movable rods 206 can be moved closer to each other, so that the two push plates 210 can be moved closer to each other. The push plates 210 can push the two sides of the cut paper pile to tidy up the cut paper pile, and the U-shaped frame 201 can be moved to push the cut paper pile, and under the action of the U-shaped frame 201 and the remaining paper pile, the other two sides of the cut paper pile can be neatly operated. When the U-shaped frame 201 is reset, the movable block 236 on the aligning plate 233 moves up under the action of the hypotenuse of the triangular plate 237, so that the aligning plate 233 moves up, and then the U-shaped frame 201 is reset, so that the movable block 236 on the aligning plate 233 moves up under the action of the hypotenuse of the triangular plate 237, so that the aligning plate 233 moves up, and then the U-shaped frame 201 is reset, and the aligning plate 233 no longer blocks the through slot on the U-shaped frame 201. At this time, the staff can remove the cut paper pile horizontally through the through slot on the U-shaped frame 201, which is convenient for subsequent processing. When the positioning frame 303 is moved, the column block 308 can slide in the straight section of the guide groove 307, which is convenient for positioning paper piles of different widths and convenient for pushing the paper piles when the paper piles are continuously cut.
