[0032] Specifically, starting the DC motor 13 can drive the rotating disk 14 to rotate.

[0036] Specifically, the position of the transverse stop block 19 can be restricted by the first card slot 18, the position of the longitudinal stop block 21 can be restricted by the second card slot 20, the movement of the L-shaped block 9 can be facilitated by the sliding groove 22, the staff can be reminded in case of a malfunction by the warning light 23, the staff can be reminded by the sound emitted by the speaker 24, the debris generated during processing can be collected through the holes 27 by the collection box 25, and the collection box 25 can be taken out conveniently by the handle 26.

[0037] Refer to Figure 1 、 Figure 2 and Figure 3 , a controller 28 is fixedly connected to the right side of the top end of the operating table 1, and the controller 28 is electrically connected to the servo motor 4, the first electric telescopic rod 8, the second electric telescopic rod 11 and the DC motor 13 respectively; a housing 29 is fixedly connected to the outside of the controller 28, and a protective cover 30 is rotatably connected to the outside of the housing 29;

[0039] Working principle: Before using the device, first,

[0040] The rotation of the turntable 14 will be driven by the start of the DC motor 13, and the rotation of the turntable 14 will directly drive the cutting knife 16 to rotate, thereby realizing the cutting of the paper bag. When performing arc cutting operations, the servo motor 4 can be started, and this motor will drive the rotating column 5 and the mechanism above it to rotate synchronously. When facing the cutting requirements of paper bags of different sizes, by activating the first electric telescopic rod 8, the L-shaped block 9 can be displaced, so as to adjust the specific position of the cutting device on the disc 6. Further, by activating the second electric telescopic rod 11, the rotation of the rotating plate 12 can be caused to realize the precise adjustment of the cutting depth;

[0041] And through the clamping mechanism 2, when the cutting tool needs to be replaced, the knob 208 needs to be rotated to drive the threaded rod 206 to rotate synchronously. Subsequently, the moving plate 202 is caused to linearly move along the right side direction of the fixed cylinder. At the same time, the clamping plate 203 also moves synchronously. Under the traction of the rotating bar 205, the left part of the clamping plate 203 will rotate and enter the square hole 201 above the fixed cylinder 17. At this time, the cutting tool 16 can be safely removed. When the knob 208 is released, the spring 207 will exert its elastic potential energy to push the moving plate back to its original position, thereby driving the clamping plate 203 to move to the left. During the movement, due to the obstruction of the rotating bar 205, the clamping plate 203 will rotate outward. At this time, a new cutting tool 16 can be placed along the direction of the fixed cylinder 17. When the cutting tool 16 moves to the outside of the clamping plate 203, the clamping plate 203 will contract due to the extrusion. Once the cutting tool 16 completely passes through the clamping plate 203, the spring 207 will push the clamping plate back to its original position again, thus completing the clamping action with the cutting tool. The model of the servo motor 4 is 130SYX, the model of the first electric telescopic rod 8 is KMF, the model of the second electric telescopic rod 11 is STYF129, and the model of the DC motor 13 is DDSM118.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
