[0023] Example:

[0024] As attached Figure 1 To Attachment Figure 3 As shown:

[0025] The utility model provides a paper packaging box punching device, comprising a punching seat 1, a plurality of leakage slots 2 are opened on the punching seat 1, a lifting seat 3 is vertically arranged on one side of the punching seat 1, a cylinder 8 is arranged on the lifting seat 3, an output shaft at the bottom of the cylinder 8 is connected with a punching plate 5, the cylinder 8 can drive the punching plate 5 to achieve lifting, a punching piece 7 corresponding to the leakage slot 2 is installed below the punching plate 5, the punching seat 1 is used to place a corrugated paper box (not folded) to be punched, and the punching plate 5 is driven down by the cylinder 8 so that the punching piece 7 presses and punches the corrugated paper box;

[0026] like Figure 2 and Figure 3As shown, the punching member 7 includes a rod body 701, a knife cylinder 703 is arranged at the bottom of the rod body 701, an inner core 706 installed on the rod body 701 is arranged in the knife cylinder 703, a push strip 708 is penetrated at the bottom of the inner core 706, and the push strip 708 is elastically connected to the inner core 706. In this embodiment, a movable groove 707 is opened in the inner core 706, one end of the push strip 708 is slidably arranged in the movable groove 707, and the push strip 708 is connected to the end wall of the movable groove 707 by a spring 709. After the knife cylinder 703 in the punching member 7 presses and cuts the corrugated paper box, the cut waste is elastically contacted by the push strip 708, and the push strip 708 squeezes the waste downward through the spring 709, so that the waste can quickly break away from the knife cylinder 703 and fall, so as to avoid the waste being stuck and accumulated in the knife cylinder 703 and affecting the next punching.

[0027] The side wall of the knife barrel 703 is provided with an observation hole 704, through which it is possible to observe whether the cut waste is accumulated in the knife barrel 703, and at the same time, it is possible to observe whether the push bar 708 is damaged or stuck.

[0028] During the process of the cylinder 8 lowering the punch plate 5 to drive the punching member 7 to cut the carton, the knife cylinder 703 is cylindrical, and the bottom blade thereof is tilted to reduce the contact area between the knife cylinder 703 and the carton, making the cutting sharper. At the same time, the waste material after cutting is tilted, reducing the probability of the waste material being stuck in the knife cylinder 703.

[0029] An inner groove 705 is provided at the bottom center of the rod body 701, and an inner core 706 is inserted into the inner groove 705 and is threadedly connected to the rod body 701. An inner hexagonal groove 710 is provided at the bottom center of the inner core 706. The inner core 706 can be rotated by a hexagonal screwdriver through the hexagonal groove 710. The position of the inner core 706 in the rod body 701 can be adjusted according to the thickness of the carton, thereby adjusting the initial height of the push strip 708 to avoid the carton hole being affected by the push strip 708 before it is completely cut. In other embodiments, the hexagonal groove 710 can also be a plum blossom groove, a flat groove, etc.
