[0027] like Figure 1-4As shown, the utility model proposes a paper punching device, including a table board 14, the upper end surface of the table board 14 is smoothly set, and a mounting frame 10 is provided at the left end of the top of the table board 14, and a lifting and punching mechanism is provided inside the mounting frame 10. A plurality of openings 1 compatible with the lifting and punching mechanism are passed through the table board 14 and located below the mounting frame 10, and the front and back sides of the table board 14 are provided with lifting components, and the lifting ends of the lifting components on both sides are respectively connected to the front and back sides of the paper placement tube 11, and a pushing component is provided on the upper end surface of the table board 14 and located on the right side of the paper placement tube 11, and a support frame 22 is provided at the bottom of the table board 14, and a reinforcing support frame 15 is provided on the left side of the support frame 22, so that the table board 14 is more stable when placed, and a first collecting component is provided at the bottom of the table board 14 and located below the plurality of openings 1, and a second collecting component is provided on the left end surface of the table board 14.

[0028] In the present invention, a plurality of papers are first placed inside the paper placement tube 11, and then the pushing component is used to push the paper at the bottom of the paper placement tube 11 toward one side of the mounting frame 10, and then the lifting and punching mechanism is started to punch the paper. At this time, the pushing component will retract and retract again. When the pushing component is retracting, the multiple papers inside the paper placement tube 11 will drop again. When the pushing component is extended, the paper at the bottom of the paper placement tube 11 can be pushed out, and the cycle is repeated, thereby realizing automatic feeding processing; after the paper is punched, the waste paper will fall into the first collecting component through the opening 1, and the paper after punching will push the paper in front along with the paper behind to fall into the second collecting component.

[0029] In an optional embodiment, the lifting and punching mechanism includes a punching drill bit 7, a movable plate 8, a first electric push rod 9 and a limiting assembly. Multiple first electric push rods 9 are spaced apart on the top of the mounting frame 10. The telescopic shafts of the multiple first electric push rods 9 pass through the top of the mounting frame 10 and are connected to the movable plate 8. The bottom of the movable plate 8 is connected to the multiple punching drill bits 7 through equidistantly distributed disassembly parts. The front and rear ends of the movable plate 8 are respectively connected to the limiting assembly. The limiting assembly includes a buffer rod 6 and a pressure plate 5. The two ends of the top of the movable plate 8 are respectively connected to the buffer rod 6. The telescopic shaft of the buffer rod 6 passes through the movable plate 8 and is connected to the pressure plate 5.

[0030] It should be noted that when punching the paper, multiple first electric push rods 9 are started, and the multiple first electric push rods 9 drive the movable plate 8 to descend. When it descends to a certain height, the pressure plates 5 on both sides will contact the paper, thereby limiting the paper. The movable plate 8 is lowered again. At this time, the punching drill bit 7 at the bottom of the movable plate 8 can punch the paper, and the punched waste will fall into the first collecting component through the opening 1.

[0031] In an optional embodiment, the disassembly part includes a mounting seat 26 and a punching drill bit 7. The mounting seat 26 is arranged at the bottom of the movable plate 8.

The telescopic axes of the third electric push rods 20 on both sides respectively pass through the first connecting plate 19 connected thereto and are respectively connected to the second connecting plates 21 on both sides.

[0034] It should be noted that by starting the third electric push rods 20 on both sides, the third electric push rods 20 on both sides can respectively drive the paper placement tube 11 to rise and fall through the second connecting plates 21 on both sides, ensuring that the gap between the paper placement tube 11 and the table board 14 is slightly larger than the thickness of the processed paper, ensuring that paper of different thicknesses can be processed; and the processing thickness of the push plate 12 is slightly smaller than the gap between the paper placement tube 11 and the table board 14.

[0035] In an optional embodiment, the pushing assembly includes a pushing plate 12, a second electric push rod 13 and a connecting assembly. The second electric push rod 13 is arranged on the top of the table top 14, and the telescopic shaft of the second electric push rod 13 is connected to the pushing plate 12 through the connecting assembly.

[0036] It should be noted that, when the second electric push rod 13 is started, the table 14 can drive the push plate 12 to move through the connecting component, so that the paper located at the bottom of the paper placement tube 11 can be pushed to the side of the mounting frame 10, thereby pushing it to the top of the table 14 and located below the mounting frame 10, so that the paper is punched by the lifting punching mechanism, and then the second electric push rod 13 is retracted. At this time, the push plate 12 is located on the right side of the paper placement tube 11, and the paper inside the paper placement tube 11 will fall down to the upper end surface of the table 14 with gravity, and the second electric push rod 13 is started again to drive the push plate 12 to move, and it is recycled to automatically load the paper, without the need for staff to repeatedly install the paper and remove the processed paper.

[0037] In an optional embodiment, the connecting assembly includes a fixing bolt 23, an insert block 24 and a limiting recess block 25. The insert block 24 is arranged on the telescopic shaft of the second electric push rod 13. The limiting recess block 25 is arranged on the side of the push plate 12 close to the second electric push rod 13. The insert block 24 is inserted into the interior of the limiting recess block 25. The fixing bolt 23 passes through the upper end of the limiting recess block 25 and extends to the interior of the insert block 24. The insert block 24 and the fixing bolt 23 are threadedly connected.

[0038] It should be noted that when it is necessary to replace paper of different thickness, the limiting recessed block 25 is separated from the inserting block 24 by rotating the fixing bolt 23, and then the limiting recessed block 25 on the push plate 12 to be used is inserted into the inserting block 24, and then the inserting block 24 and the limiting recessed block 25 are fixed by rotating the fixing bolt 23.

[0039] In an optional embodiment, the first collection component includes a collection shell 16, a collection drawer 17 and a handle 18. The collection shell 16 is arranged at the bottom of the table top 14 and below the multiple openings 1. The collection drawer 17 is inserted into the interior of the collection shell 16, and the handle 18 is arranged on the front end surface of the collection drawer 17.

[0040] It should be noted that when there is a lot of paper waste inside the collection drawer 17, the staff pulls the handle 18 to drive the collection drawer 17 out from the inside of the collection shell 16, making it easier to take out the collection drawer 17 and clean it. After cleaning, the collection drawer 17 can be inserted into the inside of the collection shell 16.

[0041] In an optional embodiment, the second collection component includes a hanging ear 2, an installation side frame 3 and a collection box 4. The installation side frame 3 is arranged on the left end face of the table top 14, and the collection box 4 is located inside the installation side frame 3. A plurality of spaced-apart hanging ears 2 are arranged above the outer end face of the collection box 4, and a plurality of hanging ears 2 are clamped on the edge of the upper end face of the installation side frame 3.

[0042] It should be noted that after the punching of the paper is completed, the subsequent paper will push the punched paper to the left, and the paper will fall into the inside of the collection box 4, thereby collecting the punched paper. When a large amount of paper is collected, the collection box 4 can be removed from the installation side frame 3, and the processed paper can be taken out. Finally, the multiple hanging ears 2 on the collection box 4 can be connected to the installation side frame 3 to realize the installation of the collection box 4.
