The punching mechanism 5 includes a cylinder 23, which is fixedly installed on the bracket 4. A punching rod 24 is threadedly connected to the piston rod of the bracket 4. A discharge hole 25 is provided on the tabletop 1. The punching rod 24 can be adapted to be aligned and inserted into the discharge hole 25. In this structure, the cardboard is placed on the tabletop 1, and then the cylinder 23 is activated to drive the punching rod 24 to move down and insert into the discharge hole 25, thereby punching the cardboard.

[0025] refer to Figures 1 to 3 As shown, a guide block 26 is fixedly installed on the bracket 4. A guide hole 27 is provided on the guide block 26. The guide block 26 is slidably connected to the punching rod 24 through the guide hole. In this structure, the guide hole 27 of the guide block 26 is used to guide the position of the punching rod 24.

[0026] refer to Figures 1 to 3 As shown, the lower part of the bracket 4 is threadedly connected to an adjusting screw 20. The front end of the adjusting screw 20 is rotatably connected to a calibration plate 21. Guide rods 22 are fixedly connected to both sides of the rear part of the calibration plate 21. The guide rods 22 are slidably connected to the bracket 4. In this structure, the distance from the edge of the cardboard to the punching position is positioned by the calibration plate 21, and the position of the calibration plate 21 is adjusted back and forth by the adjusting screw 20, so as to adjust the use according to the punching needs and improve versatility.

[0027] refer to Figures 1 to 3 As shown, a second size scale 31 is provided on the table surface 1. A pointer 32 is fixedly connected to the side of the calibration plate 21 near the second size scale 31. In this structure, the pointer 32 and the second size scale 310 are used to conveniently adjust the axial distance between the calibration rod 14 and the punching rod 24. This eliminates the need for personnel to use measuring tools to measure and adjust the axial distance between the calibration plate 21 and the punching rod 24.

[0028] refer to Figures 1 to 3As shown, two concave mounting brackets 6 are fixedly connected to the bottom of the platform 1. A sliding rod 7 is slidably connected to the mounting bracket 6. A baffle 10 is fixedly connected to the bottom end of the sliding rod 7. A spring 11 is sleeved on the sliding rod 7. A concave lifting frame 8 is fixedly connected to the sliding rod 7. A square rod 9 is fixedly connected to the lifting frame 8. A sliding block 12 is slidably connected to the square rod 9. A locking bolt 13 is threaded to the side of the sliding block 12. A calibration rod 14 is threaded to the top of the sliding block 12. A push plate 15 is rotatably connected to the bottom of the lifting frame 8. A support plate 16 is rotatably connected to the push plate 15 near the lifting frame 8. The top of the plate 16 is fixedly installed at the bottom of the tabletop 1. A vertical connecting rod 17 is rotatably connected to the end of the push plate 15 away from the lifting frame 8. A foot pressure plate 18 is rotatably connected to the lower end of the vertical connecting rod 17. A mounting plate 19 is rotatably connected to the front of the foot pressure plate 18. The mounting plate 19 is fixedly installed on the base plate 3. A strip-shaped movable hole 28 is provided on the tabletop 1. The calibration rod 14 can move along the strip-shaped movable hole 28. When the calibration rod 14 is lowered, its upper part is within the strip-shaped movable hole 28 and does not extend beyond the tabletop 1. In this structure, when punching continuous holes in the cardboard, the continuous hole... The distance between the calibration rod 14 and the punching rod 24 is adjusted by the sliding block 12 on the sliding rod 7 to match the axial distance between them with the continuous hole spacing. Then, the sliding block 12 is locked by the locking bolt 13. When drilling continuous holes, one hole is drilled first. Then, the operator steps on the foot pressure plate 18. At this time, the foot pressure plate 18 drives the vertical connecting rod 17 to move down, which drives the push plate 15 to rotate on the support plate 16. Thus, the push plate 15 can push the lifting frame 8 to slide on the fixed frame 6 through the sliding rod 7, thereby driving the calibration rod 14 to move up and protrude from the platform 1. Then, the hole drilled first is inserted into the calibration rod 14. Inside, the punching mechanism 5 is activated to punch the next hole, thus ensuring the accurate spacing of the continuous holes. At the same time, with the calibration plate 21, the straightness of the continuous holes can be ensured. After the second hole is punched, the personnel release the foot pressure plate 18. At this time, under the elastic force of the spring 11, the lifting frame 8 is driven back to its original position, thereby disengaging the calibration rod 14 from the first hole. Then, the personnel remove the cardboard from the calibration rod 14 and quickly pick up the cardboard. Then, the personnel step on the foot pressure plate 18 to make the calibration rod 14 protrude, and then the second hole is inserted into the calibration rod 14. Then, the third hole can be punched. Then, the above operation is repeated to punch the remaining holes.

[0029] In use, the entire structure controls the extension and retraction of the calibration rod 14 by stepping on it, with the hands and feet working together. Compared with the hand-lifting positioning structure in the prior art, it frees up the hands and effectively improves the efficiency of continuous punching. In addition, when not punching continuous holes, the calibration rod 14 can automatically retract to the retracted position and will not protrude from the surface 1. Therefore, the calibration rod 14 will not affect other punching needs, thus making it convenient to use.

[0030] refer to Figures 1 to 3As shown, a pointer 29 is fixedly connected to the bottom of the moving block 12, and a size scale 30 is provided on the lifting frame 8. In this structure, the pointer 29 and size scale 30 are used to conveniently adjust the axial distance between the calibration rod 14 and the punching rod 24, so that personnel do not need to use measuring tools to measure and adjust.

[0031] The implementation principle of a punching device for paper product manufacturing according to an embodiment of this application is as follows: During use, the adjusting screw 20 is rotated according to the distance between the punching position and the edge of the cardboard. The adjusting screw 20 drives the calibration plate 21 to adjust back and forth to a suitable position. Then, the sliding block 12 on the square rod 9 is slid according to the spacing of the continuous holes, thereby adjusting the distance between the calibration rod 14 and the punching position to achieve a suitable fit. After adjustment, the position of the sliding block 12 is locked by the locking bolt 13. When punching continuous holes in the cardboard, one hole is punched first. Then, the operator steps on the foot pressure plate 18. At this time, the foot pressure plate 18 drives the vertical connecting rod 17 to move downward, which in turn drives the push plate 15 to rotate on the support plate 16. Thus, the push plate 15 can push the lifting frame 8 through the sliding rod. 7. Slide on the fixed frame 6, thereby moving the calibration rod 14 upward and protruding from the surface 1. Then, insert the first hole into the calibration rod 14, start the drilling mechanism 5 to drill the next hole, thereby ensuring the accurate spacing of the continuous holes. At the same time, with the calibration plate 21, the straightness of the continuous holes can be ensured. After the second hole is drilled, the personnel release the foot pressure plate 18. At this time, under the elastic force of the spring 11, the lifting frame 8 is driven back to its original position, thereby disengaging the calibration rod 14 from the first hole. Then, the personnel remove the cardboard from the calibration rod 14 and quickly pick up the cardboard. Then, step on the foot pressure plate 18 again to make the calibration rod 14 protrude, and then insert the second hole into the calibration rod 14. Then, the third hole can be drilled. Then, the above operation is repeated to drill the remaining holes.
