[0006] In the technical solution, during the process of the motor driving the active pulley to rotate, the first driven pulley and the second driven pulley are synchronously driven, so that the cutting blade on the second driven pulley can rotate with the second driven pulley. At the same time, since the sliding seat is fixedly connected to the synchronous belt located at the upper end of the active pulley and the first driven pulley, the sliding seat will move with the synchronous belt. Since the sliding seat is slidably connected to the frame, the stability of the sliding seat moving along the frame is guaranteed. In summary, the second driven pulley is installed on the sliding seat, and the second driven pulley can also rotate while moving with the synchronous belt. The cutting blade is fixed on the second driven pulley, and finally the cutting blade can rotate during the movement to achieve paper cutting. The technical solution does not require a gear rack structure, and the synchronous belt drives the rotation and movement of the cutting blade. The structure is simpler and the production cost is reduced.

[0007] Furthermore, in order to achieve a better tensioning effect on the synchronous belt, tensioning wheels are symmetrically provided on the sliding seat, and the two tensioning wheels are respectively located on both sides of the second driven pulley.

[0008] Furthermore, in order to facilitate the installation of the cutting blade and connect the sliding seat to the synchronous belt while enabling the sliding seat to slide with the frame, the cutting blade is arranged at one end of the second driven pulley, and the other end of the second driven pulley is rotatably connected to the sliding seat, a slider is provided on the sliding seat, and a slide rail is provided at the lower end of the frame along the length direction of the frame, the slider slides with the slide rail, and a pressure block connecting plate is provided on the sliding seat, and the upper end of the pressure block connecting plate is fixedly connected to the synchronous belt located at the upper ends of the driving pulley and the first driven pulley.

[0009] Furthermore, in order to better achieve fixed connection between the pressure block connecting plate and the synchronous belt, the upper end of the pressure block connecting plate is fixedly connected to the synchronous belt located at the upper ends of the driving pulley and the first driven pulley through the synchronous belt pressure block.

[0010] Furthermore, in order to achieve a better rotary cutting effect of the cutting blade, the cutting blade is a circular cutting blade.

[0011] Furthermore, in order to facilitate the installation of the driving pulley and the first driven pulley, the frame is a long strip frame, and the driving pulley and the first driven pulley are respectively installed at two ends of the frame.

[0012] The beneficial effects of the utility model are as follows: in the technical solution, during the process of the motor driving the active pulley to rotate, the first driven pulley and the second driven pulley are synchronously driven, so that the cutting blade on the second driven pulley can rotate with the second driven pulley. At the same time, since the sliding seat is fixedly connected to the synchronous belt located at the upper ends of the active pulley and the first driven pulley, the sliding seat will move with the synchronous belt. Since the sliding seat is slidably connected to the frame, the stability of the sliding seat moving along the frame is guaranteed. In summary, the second driven pulley is installed on the sliding seat, and the second driven pulley can also rotate while moving with the synchronous belt. The cutting blade is fixed on the second driven pulley, and finally the cutting blade can rotate during the movement to achieve paper cutting. The technical solution does not require a gear rack structure, and the synchronous belt drives the rotation and movement of the cutting blade. The structure is simpler and the production cost is reduced. BRIEF DESCRIPTION OF THE DRAWINGS
