[0025] A cardboard punching device comprises a fixed seat 1, a vertical arm 2 is provided on one side of the upper end of the fixed seat 1, a mounting plate 3 is clamped on the vertical arm 2, an upper guide block 4 and a lower guide block 5 are provided on the side of the mounting plate 3 away from the vertical arm 2, a punching rod 6 is installed between the upper guide block 4 and the lower guide block 5, a punching edge 7 is provided at the lower end of the punching rod 6, a discharge hole adapted to the punching edge 7 is provided on the fixed seat 1, an arm pressing mechanism adapted to the punching rod 6 is hingedly installed on the vertical arm 2, and a reset mechanism adapted to the punching rod 6 is provided on the lower guide block 5.

[0026] Specifically, the arm pressing mechanism includes a driving arm 8 and a pressing plate 9. The lower end of the driving arm 8 is connected to the pressing plate 9. The pressing plate 9 is hinged to the vertical arm 2, and the angle between the pressing plate 9 and the driving arm 8 is an acute angle.

[0027] The reset mechanism includes a fixing ring 10, a spring 11, and a buffer ring 12. The fixing ring 10 is fixedly connected to the upper end surface of the lower guide block 5, the buffer ring 12 is fixed to the punching rod 6, and the buffer ring 12 is located below the upper guide block 4. The spring 11 connects the fixing ring 10 and the buffer ring 12, and the spring 11 is sleeved outside the punching rod 6.
