A limiting groove of the same shape as the limiting rod 15 is provided inside the inner sleeve rod 3 and the first fixed plate 6, so that the first servo motor 12 is fixed on the first fixed plate 6. Example 2

[0023] like Figure 1-4As shown, the cutting device includes a second fixed plate 7, two second fixed plates 7 are symmetrically fixed on the top surface of the base plate 1, a transmission screw 8 is slidably connected between the two second fixed plates 7, a second servo motor 14 is fixed on the side of the second fixed plate 7 close to the drive motor 5, the output end of the second servo motor 14 is fixedly connected to the transmission screw 8, a control slider 10 is threadedly connected to the transmission screw 8, the control slider 10 is rotatably connected to the end away from the transmission slide rod 9 by a control arm 11, a cutting blade 13 is fixed to the end of the control arm 11 away from the control slider 10, a first servo motor 12 is fixed on the control slider 10, the output end of the first servo motor 12 is fixedly connected to the control arm 11, so that the cutting blade 13 can cut the paper core body 2 more conveniently.

[0024] The effect achieved by the entire embodiment is that the length of the control arm 11 is greater than the control slider 10, the width of the rotating groove above the control slider 10 is greater than the width of the control arm 11 near the end of the control slider 10, a transmission slide 9 is fixed between the two second fixed plates 7, and the control slider 10 is slidably connected to the transmission slide 9 below. The transmission slide 9 is the same length as the transmission screw 8, and the length of the transmission slide 9 is the same as the length of the paper core body 2.

At this time, the cutting blade 13 cuts the rotating paper core body 2. When the cutting is completed, the control arm 11 is controlled to move the cutting blade 13 away from the paper core body 2. At the same time, the second servo motor 14 is started again, so that the second servo motor 14 drives the control slider 10 to move again, so that the cutting blade 13 cuts the paper core body 2 for the next time. When the paper core body 2 is cut, the other end of the control arm 11 is driven by the first servo motor 12 to move in a direction away from the paper core body 2, so that the cutting blade 13 is away from the paper core body 2, thereby avoiding the problem of the staff accidentally touching the cutting blade 13 and being cut when reclaiming the paper core body 2.
