[0042] The working principle of a cutting device for processing packaging cartons and boxes in the present embodiment is as follows: the staff first places the carton to be cut on the workbench 4, and then starts the second motor 32. After the second motor 32 works, it drives the bidirectional threaded rod 31 to rotate. Since the bidirectional threaded rod 31 is threadedly connected with the first connecting block 34, the guide rod 33 is slidably matched with the second connecting block 35, and the limit block 36 is fixed with the first connecting block 34 and the second connecting block 35, thereby limiting the circumferential rotation of the limit block 36 around the bidirectional threaded rod 31. Since the bidirectional threaded rod 31 is provided with two sections of threads with equal pitch and opposite rotation direction, the two limit blocks 36 can be mutually rotated in the horizontal direction during this process. Keeping them away from or close to each other is conducive to limiting the position of cartons of different lengths, and is conducive to improving the stability of the cartons during the cutting process, thereby improving the cutting quality. Subsequently, the staff starts the electric push rod 5 to raise the carton to be cut to the bottom of the limiting component 3 and press it tightly, which is conducive to reducing the probability of cutting errors caused by the displacement of the carton during the cutting process, and is also conducive to limiting the position of cartons of different thicknesses; then starting the cylinder 12 to adjust the height of the blade 23, is conducive to cutting cartons of different thicknesses; after the first motor 21 is started, it drives the blade 23 to rotate and cut the carton, which is conducive to reducing the probability of burrs at the cutting point of the carton, thereby helping to improve the cutting quality.

[0043] Example 2

[0044] The difference between this embodiment 2 and embodiment 1 is that a driving assembly for driving the cylinder 12 to reciprocate horizontally in a direction perpendicular to the bidirectional threaded rod 31 is provided on the mounting frame 11 (not shown in the figure, the driving assembly belongs to the prior art, for example, a motor drives the screw rod to rotate, the connecting block is threadedly connected to the screw rod, the connecting block is movably matched with the sliding rod, and the cylinder 12 is fixedly connected to the connecting block). The driving assembly can drive the cylinder 12 to drive the blade 23 to cut cartons with a larger width.
