That is, the servo motor 24 can directly drive the circular die holder 6 to rotate, and at the same time, due to the meshing transmission of the two gears 5, the die-cutting bottom roller 7 can rotate at the same time, and the rotation directions of the circular die holder 6 and the die-cutting bottom roller 7 are opposite to each other, so as to provide driving action for the sheet material to be die-cut.

[0027] The two ends of the screw rod 2 are respectively rotatably mounted on the side walls of the support 12, and a servo motor 21 is fixed on the outer wall of one of the supports 12, and the power output shaft is connected to one end of the screw rod 2. The screw rod 2 is threadedly sleeved with the thread sleeve on the linkage 32, that is, the servo motor 21 drives the screw rod 2 to rotate, and the linkage 32 can drive the movable plate 3 to slide horizontally under the guidance of the guide rail 11 and the slider 31. Therefore, the die-cutting tooling as a whole can realize lateral movement adjustment.

[0028] The outer wall of the circular die holder 6 is provided with a plurality of groups of rectangular grooves 61 along the axial direction, and the rectangular grooves 61 in each group are evenly arranged along the circumferential direction.
