[0024] Please see Figure 1 , Figure 2 and Figure 3 A cardboard punching device;

[0025] The device includes: a base 1 and a sliding adjustment assembly. The sliding adjustment assembly is installed on the top of the base 1. The sliding adjustment assembly includes a slide groove 3, fixing bolts 4, a mounting bracket 8, and a slider 9. The slide groove 3 is opened on the top back of the base 1. Multiple fixing bolts 4 are installed through the back of the base 1. The mounting bracket 8 is installed on the top back of the base 1 through the slide groove 3. The bottom of the mounting bracket 8 is installed with a slider 9 that matches and fits into the slide groove 3. The bottom of the slider 9 is embedded in the slide groove 3 to achieve a fitting connection. The inside of the slider 9 is installed with a fixing hole 10, and the fixing hole 10 is threadedly connected to the fixing bolt 4. The top of the base 1 is installed with a drilling platform 5. The top of the drilling platform 5 is installed with an anti-slip pad 6. The top of the anti-slip pad 6 is provided with through holes 7 of different diameters, and the through holes 7 pass through the top of the drilling platform 5.

[0026] The base 1 provides a position for the installation of the punching table 5 and the sliding adjustment assembly. The top of the punching table 5 has through holes 7 of different diameters through the anti-slip pad 6. When it is necessary to punch the cardboard, the position of the mounting frame 8 can be adjusted by the sliding adjustment assembly, thereby moving the punching head 15 above the through hole 7 of the corresponding diameter. Then, the position of the cardboard to be punched is aligned with the bottom of the punching head 15, so that the cardboard punching device can perform punching processing of different diameters, making the punching device more applicable and flexible. When the sliding adjustment assembly is in use, the bottom of the mounting frame 8 is connected to the slide groove 3 through the slider 9, which allows the mounting frame 8 to rotate. When it slides to the position to be used, the fixing bolt 4 is rotated into the fixing hole 10 for fixation. The anti-slip pad 6 improves the stability of the cardboard on the top of the punching table 5.

[0027] Specific adjustment process: First loosen the bolts, slide the mounting bracket 8 to the target position and then tighten it, and fix it by pressing the slider 9 with the bolt head.

[0028] Please see Figure 1 , Figure 3 and Figure 4 A cardboard punching device;

[0029] The device includes a hydraulic cylinder 11 and a drilling head 15. A controller 2 is installed on the top front of the base 1, and a hydraulic cylinder 11 is installed on the top front of the mounting bracket 8. The output end of the hydraulic cylinder 11 passes through the bottom of the mounting bracket 8. An mounting sleeve 12 is installed on the output end of the hydraulic cylinder 11. A fixing screw 13 is installed through the outside of the mounting sleeve 12. A drilling head 15 is installed at the bottom of the mounting sleeve 12. An mounting head 14 connected to the mounting sleeve 12 is installed at the top of the drilling head 15. A moving groove 16 is opened inside the drilling head 15. A through groove 17 is opened at the bottom of the moving groove 16. A limiting plate 19 is slidably installed inside the moving groove 16. A positioning rod 18 is installed at the bottom of the limiting plate 19. The bottom end of the positioning rod 18 passes through the through groove 17 to the bottom of the drilling head 15. The positioning rod 18 hangs down by its own weight under the limiting plate 19 and protrudes 10mm from the bottom of the drilling head 15 under normal conditions.

[0030] The limiting plate 19 is made of nylon and has a diameter 0.2mm smaller than the moving groove 16. It can slide freely without shaking.

[0031] The controller 2 is used to control the use of the hydraulic cylinder 11. The punching head 15 is inserted into the mounting sleeve 12 by the mounting head 14 and then fixed by the fixing screw 13. When the fixing screw 13 is rotated and disassembled, the punching head 15 can be replaced to accommodate different hole diameters. Each punching head 15 is provided with a moving groove 16 and a through groove 17. In order to keep the position of the cardboard to be punched perpendicular to the punching head 15, the positioning rod 18 is located below the punching head 15 under the action of the limiting plate 19. The bottom end of the positioning rod 18 is connected to the punching position of the cardboard, thereby ensuring that the punching head 15 is perpendicular to the punching position and preventing the punching head 15 from deviating from the punching position of the cardboard, which would result in the punched hole not being in the specified position. After positioning, the hydraulic cylinder 11 converts hydraulic energy into kinetic energy, driving the punching head 15 to move downward to punch the cardboard, while the positioning rod 18 enters the interior of the moving groove 16.

[0032] Punching process: After the positioning rod 18 contacts the cardboard, the hydraulic cylinder 11 continues to press down, and the limiting plate 19 slides up along the moving groove 16 until the punching head 15 contacts the cardboard; after punching is completed, the hydraulic cylinder rises, and the limiting plate 19 resets due to gravity.

[0033] Replacement steps for the punch head 15: Loosen the fixing screw 13 and pull the punch head 15 together with the mounting head 14 out of the mounting sleeve 12; select a new punch head (diameter matching the through hole 7), insert it into the mounting sleeve and tighten the fixing screw (torque 2 N·m).

[0034] The working principle is as follows: First, a Φ5mm punch head 15 is selected. The position of the punch head 15 is adjusted by the sliding adjustment component. After adjustment, it is fixed by the fixing bolt 4. Since the number of fixing bolts 4 corresponds to the Φ5.1mm through hole 7 on the punching table 5, the punch head 15 is always used above the through hole 7. The punching position on the cardboard is positioned by the positioning rod 18. After the positioning rod 18 contacts the cardboard, the hydraulic cylinder 11 is opened by the controller 2. The hydraulic cylinder 11 drives the punch head 15 at the output end to move downward to punch the cardboard.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
