[0025] Please refer to Figures 1-5, A tensioning mechanism for a bunching machine, comprising a support frame 1, the support frame 1 is installed on an external device, an adjusting mechanism is provided on the support frame 1, the adjusting mechanism includes a winding machine 2, a gear 3, a cable 4, a fixing sleeve 5, a clamping mechanism, a push block 6, a threaded disc 7, a lateral sleeve 8, a push spring 9 and an intermediate sleeve 10. The winding machine 2 is installed on the support frame 1, the gear 3 is installed on the winding machine 2, the cable 4 is slidably connected inside the gear 3, the fixing sleeve 5 is installed on the gear 3, the clamping mechanism is cooperatively connected to the fixing sleeve 5, the threaded disc 7 is threadedly connected to the fixing sleeve 5, both ends of the push spring 9 are respectively connected to the lateral sleeve 8 and the intermediate sleeve 10, the threaded disc 7 is in contact with the lateral sleeve 8, the intermediate sleeve 10 is in contact with the push block 6. There are two lateral sleeves 8, push springs 9 and intermediate sleeves 10, and the two lateral sleeves 8, push springs 9 and intermediate sleeves 10 are respectively symmetrically installed on the fixing sleeve 5, and the two intermediate sleeves 10 are respectively in contact with both sides of the slider 12. There are multiple follower rods 11 between the two threaded discs 7, and the multiple follower rods 11 are respectively arranged equidistantly along the circumference. The clamping mechanism includes a slider 12, a slide plate 13 and a limiting mechanism. The slider 12 is installed on the slide plate 13, the push block 6 is installed on the slide plate 13. A lateral groove 14 is formed on the side wall of the fixing sleeve 5, and the push block 6 is slidably connected in the lateral groove 14. The limiting mechanism is installed on the fixing sleeve 5. An expansion sleeve 15 is provided inside the fixing sleeve 5, and an expansion groove 16 is formed on the side wall of the expansion sleeve 15. The slide plate 13 is slidably connected in the expansion groove 16. Each slider 12 is provided with multiple compression springs 17, and multiple ejector rods 18 are respectively provided on the multiple compression springs 17. The top plate abuts against the cable 4. The limiting mechanism includes a limiting sleeve 19, the limiting sleeve 19 is installed on the fixing sleeve 5, rounded corners 20 are respectively formed on the limiting sleeve 19 and the fixing sleeve 5, and the cable 4 is slidably connected on the rounded corners 20. A motor 21 is provided on the support frame 1, and a belt 22 is meshed on the extending end of the motor 21, and the belt 22 is connected to the winding machine 2.

[0026] In this embodiment, when it is necessary to adjust the fixing force of the cable 4 for different situations, first, the rotation of the follower rods 11 drives the rotation of the two threaded discs 7. Since the two threaded discs 7 are respectively threadedly connected to the side wall of the fixing sleeve 5, and the two lateral sleeves 8 respectively abut against the threaded discs 7, the two intermediate sleeves 10 and the push block 6 will be driven to move correspondingly through the push spring 9. Since the push block 6 is installed on the slide plate 13, the slide plate 13 will be driven to slide along the expansion groove 16, thereby changing the positions between the multiple top plates, and thus changing the clamping force of the compression springs 17, and thus changing the fixing force between the top plate and the cable 4. Then, the tensioning force of the cable 4 can be adjusted to meet the requirements of winding and bunching the wire harness. Then, the cable 4 is conveyed into the winding machine 2 for the winding process.

[0027] More specifically, the motor 21 can drive the wire winding machine 2 to rotate and then carry out the process of bundling wires. Since round corners 20 are provided on both the fixed sleeve 5 and the limiting sleeve 19, when the wire cable 4 slides through the round corners 20, the friction can be reduced, thus ensuring the continuity of wire winding.

[0028] Working process: When it is necessary to adjust the fixing force of the wire cable 4 for different situations, first, the rotation of the follower rod 11 drives the rotation of the two threaded discs 7. Since the two threaded discs 7 are respectively threadedly connected to the side wall of the fixed sleeve 5, and the two lateral sleeves 8 respectively abut against the threaded discs 7, the push spring 9 will drive the two intermediate sleeves 10 and the push block 6 to move accordingly. Since the push block 6 is installed on the sliding plate 13, the sliding plate 13 will be driven to slide along the telescopic groove 16, thereby changing the positions between the multiple top plates. Therefore, the clamping force of the compression spring 17 will be changed, and thus the fixing force between the top plate and the wire cable 4 will be changed. Then, the tension force of the wire cable 4 can be adjusted to meet the requirements of wire winding and wire bunching. Then, the wire cable 4 is conveyed into the wire winding machine 2 for the wire winding process.

[0029] The motor 21 can drive the wire winding machine 2 to rotate and then carry out the process of bundling wires. Since round corners 20 are provided on both the fixed sleeve 5 and the limiting sleeve 19, when the wire cable 4 slides through the round corners 20, the friction can be reduced, thus ensuring the continuity of wire winding.
