Description

Technical Field

[0001] The utility model relates to the technical field of printing and cutting equipment, and in particular to a paper cutting device which is easy to fix. Background Art

[0002] In the printing process of paper products such as books and magazines, cutting is an important link. The excess part at the edge of the paper is cut off by cutting, and the paper shape is cut according to the specified size to meet the binding requirements.

[0003] In the prior art, a Chinese patent document with publication number CN115416083A discloses a paper shaping and cutting device, and specifically discloses a longitudinal frame, and two transverse frames are fixedly connected to both sides of the longitudinal frame at equal distances from the front to the back. The present invention is provided with a rubber pressure pad and a support plate, a return spring, and a bending piece, which is conducive to the staff to cut a stack of paper by first putting the paper vertically into the surface of the support plate, lifting the rubber pressure pad and pressing the paper surface to fix it, and then pushing the horizontal edge clamps on both sides of the top of the transverse frame to move horizontally through the roller to shape the two sides of the paper by lifting the rubber pressure pad and pressing the paper surface, and then the longitudinal edge clamps are pressed against the longitudinal shaping plate through the roller to expose the cutting part directly at the bottom of the cutting knife, and while moving, the rubber sleeves on both sides of the bottom of the L plate will roll on the top of the bending pieces on both sides of the longitudinal frame and the top of the transverse frame. When the required position is reached, it moves in the opposite direction and will be pressed against the curved notch on one side of the bending piece to limit the position.

[0004] When the above device is used, the fixed cutting of paper is completed by setting structures such as rubber pressure pads and support plates. However, when cutting paper, the edge of the paper is pressed and fixed by the rubber pressure pads.

Long-term use will cause the rubber pressure pads to be damaged and their elasticity to be weakened. In addition, the degree of damage to each rubber pressure pad is often different, resulting in uneven pressure between the rubber pressure pads when fixing, which may cause looseness when fixing and affect the fixing effect. Therefore, it is necessary to design a paper cutting device that is easy to fix, which can achieve fixation when cutting paper and avoid the reduction of elasticity of the fixing component during long-term use and affect the fixing effect.
