This technical solution only needs to control the movement of the knife plate on the workbench, without pushing the paper stack, saving time and effort.

[0004] The printing paper cutting device disclosed in the above document has the following defects: the cylinder of the cutting device is installed with a knife seat through a fixed connection. However, during long-term use, since there is no restriction on the angle of the knife seat, when vibration occurs, the angle of the knife seat may tilt, affecting the cutting effect of the knife plate, and the practicality is poor.

[0005] It can be seen from this that the existing paper cutting device does not have a good limiting structure between the cylinder and the knife seat, and it is necessary to improve the existing shortcomings and provide a cutting device for waste paper recycling. Utility Model Content

[0028] See also Figure 1 - Figure 6 As shown, the utility model is a cutting device for waste paper recycling, comprising a workbench 1, a guide rail 2 is installed on the upper surface of the workbench 1, a connecting frame 3 is slidably connected to the upper surface of the guide rail 2, a cylinder 4 is installed on the upper surface of the connecting frame 3, the output end of the cylinder 4 passes through the connecting frame 3 and is installed with a knife seat 5, the knife seat 5 is installed with a knife plate 7 through a connecting component 6, a slide groove is provided on the inner surface of the connecting frame 3, a limit assembly 8 is arranged inside the slide groove, the outer surface of the limit assembly 8 is slidably connected with the knife seat 5, baffles 101 are provided at both ends of the workbench 1, the baffles 101 are set to four and are symmetrically distributed, wherein a one-way screw 9 is rotatably connected between two baffles 101, a connecting rod 10 is installed between the other two baffles 101, one end of the one-way screw 9 passes through one of the baffles 101 and is installed with a driving motor 11, the outer surfaces of the one-way screw 9 and the connecting rod 10 are both slidably connected with a slider 12, and the two sliders 12 are both installed on the outer surface of the connecting frame 3 by bolts;

[0029] When cutting waste paper, firstly, the waste paper is placed on the table of the workbench 1, and the driving motor 11 is started so that the output end of the driving motor 11 drives the one-way screw 9 to rotate, so that the slider 12 moves on the one-way screw 9, and the slider 12 drives the connecting frame 3 to move synchronously during the movement. When the knife plate 7 is directly below the waste paper, the driving motor 11 is turned off, and the cylinder 4 is started so that the output end of the cylinder 4 pushes the knife seat 5 to move downward, so that the knife plate 7 cuts the waste paper. When the waste paper is cut, the cylinder 4 is operated so that the output end of the cylinder 4 is reset and drives the knife seat 5 and the knife plate 7 to move upward, and the waste paper cutting operation is completed;

[0030] The limiting assembly 8 includes a guide rod 801, which is installed inside the slide slot, one end of which passes through the connecting frame 3 and extends upward, and a connecting plate 802 is provided on the outer surface of the guide rod 801, which is installed on the outer surface of the connecting frame 3 by bolts;

[0031] The guide rod 801 can provide a better limiting effect on the knife seat 5 when the knife seat 5 is moving, so as to avoid the knife seat 5 from tilting at an angle when vibration occurs, thereby affecting the cutting effect of the knife plate 7, thereby achieving a better use effect;

[0032] A first spring 803 is sleeved on the outer surface of the guide rod 801, one end of the first spring 803 is mounted on the inner bottom of the slide slot, and a first slide plate 804 is mounted on the other end of the first spring 803, and the first slide plate 804 is slidably connected to the outer surface of the guide rod 801;

[0033] When the blade 7 cuts the waste paper, the blade holder 5 moves downward along the axis on the guide rod 801, and at the same time, the blade holder 5 pushes the first slide plate 804 to slide downward. When the first slide plate 804 slides downward, the first spring 803 gradually contracts and reduces the impact force of the blade holder 5 on the workbench 1 when it moves downward.

[0034] The upper surface of the guide rod 801 is provided with a groove, an oil storage sponge 805 is installed inside the groove, a plurality of oil outlet holes are provided on the outer surface of the guide rod 801, and a cover 806 is installed at the end of the guide rod 801;

[0035] When the knife holder 5 slides and gets stuck on the guide rod 801, the cover 806 is removed from the guide rod 801 to expose the groove, and lubricating oil is injected into the groove so that the lubricating oil soaks the oil storage sponge 805. When the oil storage sponge 805 is completely soaked, the cover 806 is installed back to the end of the guide rod 801, and the lubricating oil in the oil storage sponge 805 flows to the outer surface of the guide rod 801 through the oil outlet hole. At this time, the cylinder 4 is started, so that the output end of the cylinder 4 drives the knife holder 5 to slide up and down on the guide rod 801, so that the lubricating oil is evenly applied to the outer surface of the guide rod 801, and the guide rod 801 and the knife holder 5 are lubricated;

[0036] The connecting assembly 6 includes a limit block 601, one end of which is provided with a connecting block 602, a chamber is provided inside the connecting block 602, a second slide plate 603 is slidably connected inside the chamber, two second slide plates 603 are provided and are symmetrically distributed, a second spring 604 is installed between the two second slide plates 603, an end of the second slide plate 603 away from the second spring 604 is provided with an abutment block 605, one end of the abutment block 605 penetrates the connecting block 602 and extends outward;

[0037] The outer surface of the abutment block 605 is provided with an inclined surface;

[0038] When the knife plate 7 needs to be removed, the abutment blocks 605 at both ends of the connecting block 602 are pressed so that the abutment blocks 605 push the second slide plate 603 to move into the chamber. At the same time, the second spring 604 gradually contracts. When the pressing does not move, the limit block 601 can be pulled outward to make the connecting block 602 detach from the mounting hole, so that the knife seat 5 and the knife plate 7 are no longer fixed, thereby achieving the effect of removing the knife plate 7.
