[0025] First, the wire-binding roller 19 is sleeved on the rotating rod 15 through the disassembly hole 21, so that the two slide grooves 17 on the inner wall of the wire-binding roller 19 are aligned with the limiting protrusions 16 on the side wall of the rotating rod 15. At this time, the wire-binding roller 19 is sleeved on the rotating rod 15 through the two slide grooves 17 and the four limiting protrusions 16. When one end of the rotating rod 15 abuts against the inner wall of the wire-binding roller 19, the four limiting protrusions 16 are all moved to the positions matching the grooves 18 in the wire-binding roller 19. At this time, the cable passes through the feeding mechanism 3 on the movable substrate 1 and passes through the two wire-passing drums 8 and is wound around the wire-binding roller 19. Then, the moving block 12 in the motor slot 13 is started. The moving block 12 drives the rotating rod 15 to rotate and winds the cable around the wire-binding roller 19 , then start the No. 2 servo motor 14, the output end of the No. 2 servo motor 14 drives the rotating rod 15 to rotate clockwise, the rotating rod 15 rotates clockwise to drive the limiting protrusion 16 to rotate in the slide groove 17 to the groove 18 and abut against the inner wall of the groove 18, at this time, the two limiting protrusions 16 push the hinge roller 19 to rotate clockwise in the groove 18, and at the same time, the groove 18 can limit the limiting protrusion 16, so as to prevent the hinge roller 19 from sliding off the rotating rod 15 during the process of the rotating rod 15 driving the hinge roller 19 to rotate, and when the cable is hinged to a suitable length by the hinge roller 19, the telescopic cylinder 6 is started, and the telescopic end of the telescopic cylinder 6 pushes the limiting plate and the cable cutting knife 7 along the No. 1 frame 4 The inner wall moves downward and cooperates with the two wire-passing drums 8 to cut the cable wire. At this time, the winding and cutting of the cable wire on the wire-twisting roller 19 are completed. There is no need to manually turn the wire-twisting roller 19 to twist the cable wire, which saves time and effort. When it is necessary to twist the cables of different thicknesses, start the No. 1 servo motor 9, and the No. 1 servo motor 9 drives the moving block 12 to move upward along the inner wall of the lifting groove 10 on the threaded rod 11. The moving block 12 moves upward to drive the No. 2 servo motor 14 in the motor groove 13 to move upward. The No. 2 servo motor 14 moves upward to drive the wire-twisting roller 19 to move upward in the No. 2 frame 5, thereby increasing the distance between the lower end of the wire-twisting roller 19 and the upper end surface of the moving base plate 1, thereby avoiding The gap between the lower end of the wire-binding roller 19 and the upper end surface of the movable base plate 1 is avoided, which causes the side wall of the cable to contact the upper end surface of the movable base plate 1 due to being smaller than the thickness of the cable, so that cables of different thicknesses can also be wired by the wire-binding roller 19, and the application range is wide. When it is necessary to remove the wire-binding roller 19 from the rotating rod 15, it is only necessary to use the two handles 20 to rotate the wire-binding roller 19 on the rotating rod 15 counterclockwise. When the four limiting protrusions 16 are all out of the groove 18 and abut against the slide groove 17, the two handles 20 are used to pull the wire-binding roller 19 outward from the rotating rod 15 through the disassembly hole 21. At this time, the disassembly and separation between the wire-binding roller 19 and the rotating rod 15 can be completed, and the disassembly of the wire-binding roller 19 is easier.

[0026] The end of the threaded rod 11 which is away from the first servo motor 9 is rotatably connected to the inner wall of the lifting slot 10 .

[0027] By making the end of the threaded rod 11 away from the first servo motor 9 rotatably connected to the inner wall of the lifting groove 10, one end of the threaded rod 11 can rotate on the inner wall of the lifting groove 10;

[0028] The moving block 12 is slidably connected to the inner wall of the lifting slot 10 .

[0029] By making the moving block 12 slidably connected to the inner wall of the lifting groove 10, the moving block 12 can slide and move in the lifting groove 10 and along the inner wall of the lifting groove 10;

[0030] One end of the rotating rod 15 which is away from the second servo motor 14 abuts against the inner wall of the hinge roller 19 and is rotatably connected to the inner wall of the hinge roller 19 .

[0031] By making the end of the rotating rod 15 away from the second servo motor 14 abut against the inner wall of the hinge roller 19 and rotatably connected with the inner wall of the hinge roller 19, the end of the rotating rod 15 away from the second servo motor 14 can abut against the inner wall of the hinge roller 19 and rotate;

[0032] Wherein, both sides of the limiting plate are slidably connected to the inner wall of the No. 1 frame 4 .

[0033] By making both sides of the limit plate slidably connected to the inner wall of the first frame 4, the limit plate can be attached to the inner wall of the first frame 4 and slide up and down;

[0034] Among them, four locking universal wheels 2 are fixedly installed on the lower end surface of the movable base plate 1 .

[0035] When the mobile base plate 1 and the first frame 4 and the second frame 5 need to be moved, the four locking universal wheels 2 arranged under the mobile base plate 1 can help the mobile base plate 1 to move on the ground, thereby improving the applicable range of the mobile base plate 1 and the first frame 4 and the second frame 5;

[0036] Among them, the feeding mechanism 3 and the wire-passing drum 8 have been fully disclosed in the publication number: CN208460485U, and will not be repeated here.

[0037] The working principle of the utility model is as follows: first, the hinge roller 19 is sleeved on the rotating rod 15 through the disassembly hole 21, so that the two slide grooves 17 on the inner wall of the hinge roller 19 are aligned with the limiting protrusions 16 on the side wall of the rotating rod 15. At this time, the hinge roller 19 is sleeved on the rotating rod 15 through the two slide grooves 17 and the four limiting protrusions 16. When one end of the rotating rod 15 abuts against the inner wall of the hinge roller 19, the four limiting protrusions 16 are all moved to the position matching the groove 18 in the hinge roller 19. At this time, the cable passes through the feeding mechanism 3 on the movable substrate 1 and passes through the two wire reels 8 and is wound around the hinge roller 19. Then, the moving block 12 in the motor slot 13 is started. The moving block 12 drives the rotating rod 15 to rotate and winds the cable around the hinge roller 19. Then, the No. 2 servo motor 14 is started, and the output end of the No. 2 servo motor 14 drives the rotating rod 15 to rotate. The two limiting protrusions 16 push the wire twisting roller 19 clockwise in the groove 18 to rotate, and the groove 18 can limit the limiting protrusions 16, thereby preventing the wire twisting roller 19 from sliding off the rotating rod 15 during the rotating process of the rotating rod 15 driving the wire twisting roller 19 to rotate. When the cable is twisted to a suitable length by the wire twisting roller 19, the telescopic cylinder 6 is started, and the telescopic end of the telescopic cylinder 6 pushes the limiting plate and the cable cutting knife 7 to move downward along the inner wall of the No. 1 frame 4 and cooperates with the two wire passing drums 8 to cut the cable. At this time, the winding and cutting of the cable on the wire twisting roller 19 are completed, and there is no need to manually rotate the wire twisting roller 19 to twist the cable, which saves time and effort.

[0038] When it is necessary to perform wire twisting on cables of different thicknesses, start the No. 1 servo motor 9, which drives the moving block 12 to move upward on the threaded rod 11 along the inner wall of the lifting slot 10, and the moving block 12 moves upward to drive the No. 2 servo motor 14 in the motor slot 13 to move upward, and the No. 2 servo motor 14 moves upward to drive the wire twisting roller 19 to move upward in the No. 2 frame 5, thereby increasing the distance between the lower end of the wire twisting roller 19 and the upper end surface of the moving base plate 1, thereby avoiding the side wall of the cable contacting the upper end surface of the moving base plate 1 due to the distance between the lower end of the wire twisting roller 19 and the upper end surface of the moving base plate 1 being less than the thickness of the cable, so that cables of different thicknesses can also be twisted by the wire twisting roller 19, and the application range is wide;

[0039] When it is necessary to remove the hinge roller 19 from the rotating rod 15, it is only necessary to use the two handles 20 to rotate the hinge roller 19 on the rotating rod 15 counterclockwise. When the four limiting protrusions 16 are all out of the grooves 18 and abut against the slide grooves 17, the two handles 20 are used to pull the hinge roller 19 out of the rotating rod 15 through the disassembly hole 21. At this time, the disassembly and separation between the hinge roller 19 and the rotating rod 15 is completed, and the disassembly of the hinge roller 19 is easier.

[0040] When the mobile base 1 and the first and second frames 4 and 5 need to be moved, the four locking universal wheels 2 arranged under the mobile base 1 can help the mobile base 1 to move on the ground, thereby improving the application range of the mobile base 1 and the first and second frames 4 and 5.
