[0014] In the above technical solution, the collecting groove can collect the debris after punching.

[0015] Furthermore, a plurality of brake universal wheels are installed at the bottom of the collecting tank, and a push handle is installed on the collecting tank.

[0016] In the above technical solution, a brake universal wheel and a push handle are provided to facilitate the movement of the collecting tank.

[0017] Furthermore, the inner bottom surface of the collecting trough is an inclined surface, and a discharge hole is formed through the vertical side wall of the collecting trough. The discharge hole is located at the lowest point of the inclined surface. The collecting trough is hinged with a cover plate, and the cover plate is detachably connected to the outer wall of the collecting trough to seal the discharge hole.

[0018] In the above technical solution, an inclined surface is provided and a discharge port is opened at the lowest point of the inclined surface so as to facilitate the debris to leave the collecting tank.

[0019] Furthermore, the cover plate is installed with a first magnet, and the outer wall of the collecting tank is embedded with a second magnet, and the first magnet can be attracted to the second magnet.

[0020] In the above technical solution, magnet one can be attracted to magnet two so that the cover plate can block the discharge port.

[0021] To summarize, the present application has the following technical effects: if it is necessary to replace a fixing with a different spacing between punching needles, the fixing can be replaced by removing the bolts and nuts, and the chip removal plate can be snapped into place with the upper surface of the workbench to facilitate replacement of the chip removal plate with different spacing between chip holes, so that the position of the chip removal hole can be adapted to the position of the punching needle.

[0029] Please refer to the attached drawings in the instruction manual. Figure 1 and Figure 2 One embodiment of the present application provides a cardboard punching machine, including a frame 1, the frame 1 is formed with a horizontal workbench 11, a hydraulic cylinder 4 is installed on the frame 1, the hydraulic cylinder 4 is used to drive a fixed part 2 to move vertically and linearly, so that the fixed part 2 can move vertically and linearly close to or away from the workbench 11, the fixed part 2 is installed with seven punching needles 3 for punching cardboard, a card slot 111 is provided on the workbench 11, the card slot 111 is connected with a chip removal plate 6, when the chip removal plate 6 is placed in the card slot 111, its upper surface can be flush with the upper surface of the workbench 11, the chip removal plate 6 is provided with seven chip removal holes 61 corresponding to the seven punching needles 3, multiple cardboards can be placed on the chip removal plate 6 and the workbench 11, and the hydraulic cylinder 4 can drive the fixed part 2 to move vertically and linearly so that the punching needles 3 contact the cardboard. A collecting trough 16 is placed below the frame 1, and the chips after punching can enter the collecting trough 16 through the chip removal holes 61 for collection. Among them, three limiting plates 15 for limiting the position of the cardboard are installed on the upper surface of the workbench 11. The three limiting plates 15 can contact with the three side edges of the cardboard at the same time to limit the position, so that the punching position of the cardboard is accurate.

[0030] Please refer to the attached drawings in the instruction manual. Figure 3 and Figure 4, four connection holes 8 are provided on both the fixing plate 7 and the mounting plate 5, and the four connection holes 8 on the fixing plate 7 can correspond one to one to the four connection holes 8 on the mounting plate 5. The connection holes 8 on the fixing plate 7 and the connection holes 8 on the mounting plate 5 are used to penetrate the same bolt 9, and the bolt 9 is threadedly connected with a nut 10, so that the fixing plate 7 is fixed relative to the mounting plate 5. This design can be convenient. Due to different customer needs, the punching spacing on the cardboard of the same specification is different. When it is necessary to replace the fixing part 2 with a different spacing of the punching needle 3, this design facilitates the disassembly of the fixing part 2, and at the same time, the chip removal plate 6 can be taken out of the card slot 111, and the chip removal plate 6 corresponding to the position of the punching needle 3 can be replaced, which is more convenient.

[0031] Please refer to the attached drawings in the instruction manual. Figure 4 Two pressing plates 12 are placed on the side of the fixing part 2 close to the workbench 11.
