the tool apron 21 is in transmission coupling with the driving device 30 so as to drive the tool apron 21 to rotate;
and the blade 22 is arranged on the tool holder 21 and rotates along with the tool holder.
In operation, with reference to the orientation shown in fig. 2, paper is fed from the left side and laid on the press 10, while the blade holder 21 is driven to rotate. When the blade of the blade 22 presses on the paper, pressure is formed between the blade 22 and the pressure-bearing device 10, the paper is cut and divided, no burr is generated, and the cut paper is output from the right side. In a preferred embodiment, the blade 22 makes one cut with one rotation of the blade holder 21.
Preferably, the pressure bearing device 10 is a rotatable pressure bearing roller which rotates along with the advance of the paper, so that the paper is normally conveyed forwards after being cut.
Preferably, a knife groove 23 is provided on one side end surface of the knife holder 21, and the blade 22 is provided in the knife groove 23.
Further, in the knife groove 23, a spring 24 is provided inside the blade 22.
