[0026] The working principle of this utility model:

[0027] First, start the two servo motors 5 to rotate forward and reverse respectively, and drive the two conveying wheels 7 to rotate in opposite directions through the two servo motors 5. The cable body 15 is conveyed downward by the rotation of the conveying wheels 7. The cable body 15 is kept moving in a straight line by the first wire barrel 8 and the second wire barrel 9. The downward movement of the cable body 15 triggers the contact sensor 18. The contact sensor 18 starts the cylinder 3 through the controller and turns off the servo motor 5. The cylinder 3 drives the cutting knife 4 to cut the cable body 15. Then, the first electric push rod 13 is started through the controller 2, and the first electric push rod 13 drives the support block 10 to move upward. The lifting block 12 moves in the direction of the cable body 15. At this time, the cut cable body 15 falls down by gravity. Then, the servo motor 5 is started by the controller 2 to drive the conveying wheel 7 to continue to convey the cable body 15. At the same time, the first electric push rod 13 is started by the controller 2 to drive the support block 10 to move and reset to the bottom of the cable body 15. The cable body 15 is detected again by the contact sensor 18. By adjusting the height of the contact sensor 18, the cutting length can be adjusted. The second electric push rod 11 is started by the controller 2. The height of the contact sensor 18 can be adjusted by driving the lifting block 12 to rise and fall by the second electric push rod 11.
