[0035] It should be noted that, unlike traditional paper cutting machines, the rotary cutter 2 is used to cut paperboard, and the multi-edge cutter 2 has a certain downward pressure on the paperboard during rotation cutting. Compared with the circular cutter 2, the cutting efficiency is faster.

[0036] In this embodiment, the first drive assembly 4 includes a motor 41, a linear guide rail 42 and a first transmission assembly 43, the motor 41 drives the first transmission assembly 43 and drives the bracket 3 arranged on one side of the moving end of the first transmission assembly 43 to move along the linear guide rail 42. It should be noted that the bracket 3 is driven by the motor 41 to move linearly, and the feed speed, feed direction and rotation speed of the cutter during cutting are related to the rotation speed and rotation direction of the motor 41.

[0037] Please refer to Figure 7 In this embodiment, the transmission structure of the first transmission assembly 43 includes belt transmission, chain transmission or other different transmission modes.
