Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Wheel b8, the outer wall of gear a7 is meshed with the outer wall of gear b8. In the process of rotating shaft a4 driving skeleton 5 to rotate, gear a7 rotates under the action of gear b8, thereby driving rotating shaft b6 to rotate. The front end of rotating shaft b6 is fixedly connected with wire-releasing mechanism 9, and the end of transmission assembly is fixedly connected with the back of wire-releasing mechanism 9, thereby driving wire-releasing mechanism 9 to rotate. The end of rotating shaft a4 is fixedly connected with turntable 10, and the inner wall of turntable 10 is provided with three groups of wire holes 11. The three groups of wire-releasing mechanisms 9 straighten the cable wires through the corresponding wire holes 11, and according to the rotation of turntable 10, the transmission assembly is used to adjust the wire-releasing angle of wire-releasing mechanism 9 to prevent jamming during wire-releasing process.

[0031] Furthermore, a slide rail 12 is provided on the outer wall above the workbench 1, and a wire bundling mechanism 13 is slidably connected to the inner wall of the slide rail 12. The wire bundling mechanism 13 is used to gather the cable wires together and bundle them together as the rotating shaft a4 rotates. A handle 23 is fixedly connected to the outer wall of the wire bundling mechanism 13, and a block 25 is elastically connected to the inner wall of the handle 23 through a return spring a24. One end of the return spring a24 is fixedly connected to the inner wall of the handle 23, and the other end of the return spring a24 is fixedly connected to the bottom end of the block 25. Pressing the block 25 inwards can squeeze the return spring a24 to retract it. At the same time, the elastic force generated by the deformation of the return spring a24 gives the block 25 an upward thrust to reset it. A slot 26 is provided on the side wall of the slide rail 12, and the inner wall of the slot 26 is engaged with the outer wall of the block 25. After the block 25 is pressed inwards until it is released from the slot 26, the wire bundling mechanism 13 can be driven to slide along the slide rail 12 by the handle 23. In this way, the distance between the wire bundling mechanism 13 and the turntable 10 is adjusted, the tension of the cable wire during the bundling process is changed, and the cable wire is prevented from breaking during the bundling process, and the outer wall of the handle 23 slides with the inner wall of the slide rail 12.

[0032] Reference Figure 1-Figure 3The upper outer wall of the workbench 1 is fixedly connected with a support frame b14, and a motor b15 is welded on the back of the support frame b14. A rotating shaft c16 is fixedly connected to the output shaft of the motor b15. The outer wall of the rotating shaft c16 is detachably connected with a bunching roller 17. The motor b15 is driven to make the rotating shaft c16 drive the bunching roller 17 to rotate, thereby retracting the bundled cable and driving the entire wire bundling process. The outer wall of the rotating shaft c16 is detachably connected with a fixed block 18. The inner wall of the fixed block 18 is elastically connected to the limit block 20 through a reset spring b19. One end of the reset spring b19 is fixedly connected to the inner wall of the fixed block 18, and the other end of the reset spring b19 is fixedly connected to the back of the limit block 20. The limit block 20 is fixedly connected, and the limit block 20 can squeeze the reset spring b19 to retract. At the same time, the elastic force generated by the deformation of the reset spring b19 gives the limit block 20 a thrust in the opposite direction, prompting it to reset. A pull rod 22 is fixedly connected to the back of the limit block 20, and the outer wall of the pull rod 22 is slidably connected to the inner wall of the fixed block 18. Pulling the pull rod 22 outward can pull the limit block 20 to move outward. Two groups of limit grooves 21 are provided on the outer wall of the rotating shaft c16, and the outer wall of the limit block 20 is clamped with the inner wall of the limit groove 21. After pulling the pull rod 22 outward until the limit block 20 is released from the limit groove 21, the fixed block 18 can be removed from the rotating shaft c16, thereby replacing the focusing roller 17.

[0033] Working principle: Start the motor a3 to make the shaft a4 drive the skeleton 5 to rotate. At the same time, under the action of the gear b8, the gear a7 rotates while making a circular motion, driving the shaft b6 and the pay-off mechanism 9 to rotate, maintaining the best pay-off angle, and the paid-out cable wire passes through the wire hole 11 and is bundled together under the action of the wire bundling mechanism 13. When adjusting the wire bundling mechanism 13 according to the material or size of the cable wire, press the card block 25 downward to push it out of the card slot 26, and then slide the handle 23 to drive the wire bundling mechanism 13 to slide along the slide rail 12 to adjust the distance between the wire bundling mechanism 13 and the wire hole 11, and change the tension of the cable wire during the bundling process to prevent it from breaking. The motor b15 starts to rotate the bundling roller 17 to retract the bundled cable. When the bundling roller 17 needs to be replaced, pull the two sets of pull rods 22 outward to release the clamping connection between the limit block 20 and the limit slot 21, and then the fixed block 18 can be removed to replace the bundling roller 17.
