The first motor 204 preferably adopts a servo motor. The servo motor is a prior art. The servo motor is a motor that can achieve precise position control through feedback signals. It is usually composed of a motor, an encoder, a controller and a driver. In the servo system, the encoder continuously monitors the position of the motor and feeds back the actual position information to the controller. The controller will accurately control the motor through the driver according to the set position and speed requirements to achieve the desired position and speed. A plurality of sets of rotating shafts 201 are rotatably arranged on the rotating disk 2. The rotating shafts 201 are arranged in two to eight groups, preferably three groups, and the three groups are evenly distributed on the rotating disk 2. After the first motor 204 drives the rotating disk 2 to rotate 120 degrees each time, it stops at the current position for a period of time. In this process, loading, cutting and unloading can be performed at the same time, which can improve the cutting efficiency. The three sets of rotating shafts 201 are respectively fixed at one end. A mounting plate 202 is provided, on which a rotating rod 3 is detachably connected, and the diameter of the rotating rod 3 matches the inner wall of the paper tube, so that the paper tube can be sleeved on the rotating rod 3 and can also rotate with the rotating rod 3, and a driving part for driving the rotating shaft 201 to rotate is provided on the first fixed plate 101. By providing three groups of rotating shafts 201, that is, three groups of rotating rods 3 are correspondingly provided, corresponding to the three stations of loading, cutting and unloading, the cutting efficiency can be improved; two groups of connecting plates 4 are lifted and lowered on the frame 1, wherein, in the two groups A connecting block is fixedly arranged between the connecting plates 4, a dust collecting groove is provided on the connecting block, a dust collecting box is fixedly arranged at the bottom of the frame 1, and the dust collecting groove is connected to the dust collecting box through a pipeline. By providing the connecting block, on the one hand, it can be ensured that the two groups of connecting plates 4 are lifted and lowered at the same time, and the lifting and lowering are not synchronized, so as to ensure the normal use of the knife bar 5. On the other hand, a dust collecting groove is provided on the connecting block, so that the dust generated by cutting can be collected as much as possible, which helps to reduce the diffusion of dust. A knife bar 5 is rotatably arranged between the two groups of connecting plates 4, and multiple groups of cutting knives 5 are evenly arranged on the knife bar 5. 01.
