Specific implementation manner

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 - 4 , the present invention provides a technical solution: a paper cutting device, including a workbench 1, four support legs 2 are fixedly installed at the bottom of the workbench 1, a support plate 3 is fixedly installed on the opposite sides of the four support legs 2, a suction pump 26 is fixedly installed on the top of the support plate 3, the input end of the suction pump 26 is communicated with an air pipe 25, the other end of the air pipe 25 is communicated with an air collecting frame 24, the output end of the suction pump 26 is communicated with a dust filter box 22 through a pipeline, two slide rails 6 are fixedly installed on the top of the workbench 1, a plurality of adjustment holes 7 are opened inside the two slide rails 6, three slide seats 8 are slidably installed on the outer sides of the two slide rails 6 respectively, two positioning bolts 9 are inserted into the interiors of the three slide seats 8 respectively, scale lines 11 are arranged on the outer sides of the two slide rails 6 respectively, an operation frame 13 is fixedly installed on the tops of the three slide seats 8, a plurality of hydraulic telescopic cylinders 14 are fixedly installed through the top of the operation frame 13, a pressing plate 15 is fixedly installed at the output end of the hydraulic telescopic cylinder 14, a silica gel plate 1501 is fixedly installed at the bottom of the pressing plate 15, the input end at the top of the hydraulic telescopic cylinder 14 is communicated with a connecting pipe 16, one end of the connecting pipe 16 is communicated with a hydraulic power device 17, two sliding frames 18 are fixedly installed on the inner wall of one end of the operation frame 13, a slide bar 20 is slidably installed inside the two sliding frames 18, a cutter 21 is fixedly installed at the bottom of the slide bar 20, a hydraulic telescopic column 19 is fixedly installed at the top of the slide bar 20, a second push rod 5 is fixedly installed at one end of the top of the workbench 1, two first push rods 4 are fixedly installed at one end of the top of the workbench 1, push plates 12 are fixedly installed at the output ends of the second push rod 5 and the first push rods 4 respectively, a plurality of first air holes 10 are opened on the top of the workbench 1, and a plurality of second air holes 23 are opened on the top of the workbench 1.

[0020] Working principle of the above technical solution: During use, the operator places the pre-stacked papers to be cut on the top of the workbench 1, on the opposite sides of the first push rod 4 and the second push rod 5, and starts the first push rod 4 and the second push rod 5 to extend. The papers are stacked neatly by the push plate 12. Then, the second push rod 5 extends to push the papers to the cutting position through the push plate 12. Next, the hydraulic power device 17 starts to output hydraulic pressure. There is hydraulic oil in both the connecting pipe 16 and the hydraulic telescopic cylinder 14. At this time, the hydraulic oil is gradually output, and the output end of the hydraulic telescopic cylinder 14 is pushed out, prompting the pressing plate 15 and the silica gel plate 1501 to press on the top of the papers. Due to the power action of the hydraulic pressure, multiple hydraulic telescopic cylinders 14 move down synchronously, so that the downward pressure for fixing the papers is uniform and appropriate, reducing the wrinkles of the papers. Then, the hydraulic telescopic column 19 extends to drive the sliding rod 20 and the cutting knife 21 to extend, cutting the papers. The overall operation effect is good, facilitating the uniform and appropriate cutting pressure on the papers, reducing the wrinkles of the papers, and indirectly increasing the cutting accuracy.

[0021] In another embodiment, as Figures 1 - 3 shown, the top end of the air collecting frame 24 is fixedly installed at the bottom of the workbench 1, and the dust filtering box 22 is fixedly installed on the top of the support plate 3.

[0022] The air collecting frame 24 applies the air extraction effect of the air pipe 25 to the bottom of the workbench 1, thereby prompting the first air holes 10 and the second air holes 23 to lead out the air flow on the top of the workbench 1, facilitating air extraction and filtration and air flow diversion.

[0023] In another embodiment, as Figures 1 - 4 shown, the adjusting holes 7 are linearly and evenly arranged inside the slide rail 6. The specification size of the positioning bolt 9 is adapted to the specification size of the adjusting holes 7. The scale lines 11 are opened on the top of the workbench 1.

[0024] The adjusting holes 7 provide positions for the adjustment and fixation of the slide seat 8, and cooperate with the scale reference of the scale lines 11, facilitating the operator to adjust the cutting position and fixing by inserting the positioning bolt 9 into the inside of the slide seat 8 and the adjusting holes 7, facilitating adjustment and fixation and assisting the operation.

[0025] In another embodiment, as Figures 1 - 4 shown, the hydraulic power device 17 is fixedly installed on the top of the operation frame 13. The hydraulic telescopic cylinders 14 are arranged in a rectangular and linear uniform distribution inside the operation frame 13, and are in close contact with the outer side of the pressing plate 15. There is hydraulic oil in both the connecting pipe 16 and the hydraulic telescopic cylinder 14.

[0026] After the hydraulic power unit 17 is fixed, it outputs hydraulic oil, which is pushed into the connecting pipe 16 and the hydraulic telescopic cylinder 14, so that the pressure evenly pushes out the pressing plate 15. The overall structure is stable, facilitating the equalization of the acting force, making the pressure balanced and stable, and avoiding uneven pressure. In addition, in another embodiment, the hydraulic power unit 17 can be replaced with a device that outputs air flow. The air flow is input into the hydraulic telescopic cylinder 14 through the connecting pipe 16, thereby moving the pressing plate 15 downward, and a stable air pressure elastic force can be applied to the paper, facilitating stable different operations, such as different pressures for rough paper and delicate paper, and reducing the damage to the paper caused by applying pressure to the paper.

[0027] In another embodiment, as Figures 1 - 3 shown, the hydraulic telescopic column 19 is fixedly installed at the top of the inner cavity of the working frame 13. The positions of the first push rod 4 and the second push rod 5 correspond to each other, and the bottom of the push plate 12 is in contact with the top of the workbench 1.

[0028] After the hydraulic telescopic column 19 extends, it drives the slide rod 20 to extend, thereby controlling the cutter 21 to move downward to cut the paper. The first push rod 4 and the second push rod 5 push the paper to a suitable position, and through the push of the second push rod 5, the paper is stabilized at a suitable working position, facilitating auxiliary operations.

[0029] In another embodiment, as Figures 1 - 4 shown, the second air holes 23 are linearly and evenly arranged and distributed through the top of the workbench 1. The positions of the second air holes 23 correspond to the positions of the adjustment holes 7. The first air holes 10 are rectangularly and evenly distributed on the top of the workbench 1. The positions of the first air holes 10 correspond to the positions of the slide rails 6. The bottoms of the first air holes 10 and the second air holes 23 are both connected to the inside of the air collecting frame 24.

[0030] Through the provided first air hole 10 and second air hole 23, when there are certain debris and powders generated during the paper cutting operation, the suction pump 26 is started to pump air through the air pipe 25. The air flow enters into the inside of the air collection frame 24 through the first air hole 10 and the second air hole 23, and brings the debris and powders together. It is transported to the dust filter box 22 through the suction pump 26 to filter and discharge the paper debris and powders in the air flow, which is convenient for reducing the floating of debris and powders, protecting the respiratory health of the operating personnel and indirectly prolonging the service life of the equipment parts. During the cutting process, the position of the sliding seat 8 is adjusted through the adjusting hole 7 and the positioning bolt 9. The cutting position of the cutter 21 with respect to the paper is fixed. Through the distribution of the second air hole 23 corresponding to the position of the adjusting hole 7, the air flow is guided to the position where the cutter 21 cuts the paper. During cutting, the generated debris and powders are guided, and the first air hole 10 guides the air flow around the slide rail 6, which is convenient for forming an air flow guiding wall around the paper being cut, thereby reducing the drift of paper debris and powders, facilitating the air flow to correspond to the periphery and the cutting position, and thus reducing the overflow of paper debris and powders, increasing the purification effect.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
