Specifically, in the packaging box production line described in this embodiment, first, the loading device 2 transfers the flat packaging box to the positioning mechanism of the frame 11. After the positioning mechanism positions the flat packaging box, the clamping mechanism 12 clamps the packaging box. Then, the clamping mechanism 12 moves the packaging box to the high-frequency device 4 to print the bending lines and generate perforations of specific shapes. Then, the clamping mechanism 12 moves the packaging box to the die-cutting device 3 for edge trimming. Then, the clamping mechanism 12 moves the packaging box to the waste discharge device 5. After the waste discharge device 5 ejects the perforated waste of the packaging box, finally, the clamping mechanism 12 moves the packaging box to the unloading device 6 for unloading, thereby completing the automated production of the packaging box.
