Description

Technical Field

[0001] The utility model relates to the technical field of automatic burr-free paper cutting devices, in particular to a full-automatic burr-free paper cutting device. Background Art

[0002] In the process of paper product production and printing, paper needs to be cut to meet the needs of subsequent binding and printing. Paper cutters are used to handle paper cutting needs before and after printing, and often cut stacked paper.

[0003] The existing automatic paper cutting device, as described in Patent No. CN220313439U: a protective paper cutting device, includes a base, a fixed frame is fixedly connected to the base, a cutting knife is arranged in the fixed frame, a hydraulic cylinder is also fixedly connected to the fixed frame, a piston rod of the hydraulic cylinder is fixedly connected to the cutting knife, at least one side of the fixed frame is rotatably connected to an arc plate, the arc plate and the outside of the fixed frame are fixedly connected to connecting members, and a second spring is fixedly connected between the two connecting members. In the utility model, when the hydraulic cylinder drives the cutting knife to move downward and then cuts the paper through the cutting knife, the arc plate is resisted by the resisting unit, so the paper can be resisted by the resisting roller, thereby fixing the position of the paper. At the same time, the protective cloth can be pulled open by the resisting, so that protection can be provided when the cutting knife is cutting, so as to avoid accidental injury during the cutting process of the cutting knife and avoid safety hazards.

[0004] However, although the above patent drives the cutting knife to move downward by the hydraulic cylinder, and then when the cutting knife cuts the paper, the resistance unit resists the arc plate, so the resistance roller can resist the paper, thereby fixing the position of the paper. At the same time, the protection cloth can be pulled open by the resistance, so that protection can be provided when the cutting knife is cutting, avoiding accidental injury during the cutting process of the cutting knife and avoiding safety hazards. However, the above patent requires workers to push the paper to the position of the cutting knife. Manually pushing the paper is not only labor-intensive, but also there are certain safety hazards when individuals operate at the cutting knife position for a long time. Utility Model Content

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0022] See also Figure 1-4 The utility model provides a technical solution: a fully automatic burr-free paper cutting device, comprising a platform 1, a mounting plate 2 is vertically mounted on the top of the platform 1, and a paper pushing assembly is arranged on the mounting plate 2, a mounting frame 7 is vertically mounted on the top of the platform 1, and a cutting assembly is arranged on the top of the mounting frame 7, and a cutting hole 10 is vertically penetrated through the top of the platform 1 below the mounting frame 7;

[0023] Specifically, when the paper on the top of the platform 1 is pushed under the mounting frame 7 for cutting, the first hydraulic rod 6 is activated to drive the push paper board 5 to move horizontally. When the push paper board 5 moves horizontally, the sliding block 4 installed on the top of the push paper board 5 is slidably sleeved on the outside of the guide rod 3 to guide it. The push paper board 5 at the bottom of the sliding block 4 can push the paper under the mounting frame 7 for cutting.

[0024] Further, the paper pushing assembly includes a guide rod 3, a sliding block 4, a first hydraulic rod 6 and a paper pushing board 5. The guide rod 3 is horizontally installed on the outer side of the mounting plate 2, and the sliding block 4 is slidably sleeved on the outer side of the guide rod 3. The paper pushing board 5 is vertically installed at the bottom of the sliding block 4. The first hydraulic rod 6 is horizontally installed on the outer side of the mounting plate 2, and the output end of the first hydraulic rod 6 is connected to the outer side of the paper pushing board 5.

[0025] Furthermore, an electric push rod 12 is vertically installed at the bottom of the sliding block 4, and a limiting plate 13 is horizontally installed at the output end of the electric push rod 12;

[0026] Specifically, when the paper is pushed, the paper may bend due to friction. At this time, the electric push rod 12 installed at the bottom of the sliding block 4 is started to drive the limiting plate 13 to move downward, and the limiting plate 13 stops moving after it approaches the paper. The limiting plate 13 does not apply downward pressure to the paper, thereby preventing the paper from being bent.

[0027] Furthermore, a collection box 11 is installed at the bottom of the platform 1, and the collection box 11 is located directly below the cutting hole 10;

[0028] Specifically, after the paper is cut by 9, the debris from the cutting enters the collection box 11 for collection.

[0029] Furthermore, the cutting assembly includes a second hydraulic rod 8 and a cutter 9, a plurality of second hydraulic rods 8 are vertically installed on the top of the mounting frame 7, and the output ends of the second hydraulic rods 8 are all connected to the top of the cutter 9;

[0030] Specifically, after the paper is pushed to the position just above the cutting hole 10 , the second hydraulic rod 8 is started to push the cutter 9 to move up and down, so that the paper can be cut by the cutter 9 .

[0031] Furthermore, a side of the top of the platform 1 away from the mounting plate 2 is chamfered;

[0032] Specifically, after the cutting is completed, the first hydraulic rod 6 continues to push the paper to move horizontally, and continues to push the cut part to the side away from the mounting plate 2, and chamfers the top of the platform 1 to facilitate the cut paper to move out of the top position of the platform 1.

[0033] Working principle: When using the fully automatic burr-free paper cutting device, when the paper on the top of the platform 1 is pushed under the mounting frame 7 for cutting, the first hydraulic rod 6 is started to drive the push paper board 5 to move horizontally. When the push paper board 5 moves horizontally, the sliding block 4 installed on the top of the push paper board 5 is slidably sleeved on the outside of the guide rod 3 to guide it. The push paper board 5 at the bottom of the sliding block 4 can be pushed under the mounting frame 7 for cutting. After the paper is pushed to the top of the cutting hole 10, the cutter 9 is pushed up and down by starting the second hydraulic rod 8, and the paper can be cut by the cutter 9. After the cutting is completed, the first hydraulic rod 6 continues to push the paper to move horizontally, and the cut part continues to be pushed to the side away from the mounting plate 2, and chamfers are performed through the top of the platform 1 to facilitate the cut paper to move out of the top position of the platform 1. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
