The wires are discharged from the wire outlet. When the size of the transmission gap needs to be adjusted for the wires of the same batch with different thicknesses, the cylinder 46 corresponding to the wire that needs to be adjusted is turned on, and the output end of the cylinder 46 pushes the adjustment block 45 to move, thereby driving the rotating plate 43 to rotate on the outer wall of the fixed shaft 40, so that the height of the circular gear 44 can be controlled to adjust the transmission width between the transmission roller 42 and the circular gear 44 to meet the production needs of wire harnesses of different types and specifications, and each transmission channel can be adjusted separately without affecting each other, thereby improving the manufacturing efficiency and production flexibility of the wire harness.

[0040] Working principle: When this device is needed, the technician can process multiple wires by first turning on the motor 36 fixed to the outer wall of the protective shell 35. The output end of the motor 36 can drive the first gear 38 to rotate through the transmission belt 37. When the first gear 38 rotates, it can drive the steering gear 41 and the second gear 39 to rotate clockwise at the same time through the meshing connection. When the second gear 39 rotates, it can drive the circular gear 44 to rotate counterclockwise, and then the wire can be discharged through the wire outlet of the outer wall of the protective shell 35 through the transmission roller 42. When adjusting the wires of different thicknesses of the same batch, turn on the cylinder 46 corresponding to the wire that needs to be adjusted. The output end of the cylinder 46 can push the adjustment block 45 to move, which can The rotating plate 43 is driven to rotate on the outer wall of the fixed shaft 40, so that the height of the circular gear 44 can be controlled to adjust the transmission width between the transmission roller 42 and the circular gear 44, which can adapt to the production needs of wire harnesses of different types and specifications, greatly improving the manufacturing efficiency of the wire harness.

When the slider 16 approaches the second sensor 19, the second sensor 19 will issue a reminder to the technician to handle it, so as to prevent the wire from breaking due to tension, affecting safety and wire quality. It is easy to deviate during the transmission of the wire. Turn the handle 26, the handle 26 can drive the movable plate 27 to rotate, and then push the moving block 21 to slide, thereby driving the first correction on the upper surface of the moving block 21. The wheel 22 moves, and then the wire is placed between the first correction wheels 22 at both ends, the turning handle 26 is released, and the first spring 24 rebounds, which can pull the positioning column 23 to slide inside the limit block 25, thereby driving the first correction wheel 22 on the upper surface of the moving block 21 to engage with the first correction wheel 22 on the upper surface of the limit block 25, so as to correct the transmission route of the wire and facilitate threading. At the same time, the pull handle 29 is pulled upward, and the pull handle 29 can drive the pressure block 31 to slide upward inside the guide block 32, thereby driving the second correction wheel 33 on the inner wall of the pressure block 31 away from the second correction wheel 33 on the outer wall of the connecting shaft 34. After the cable is placed between the second correction wheels 33 at both ends, the pull handle 29 is released, and the second spring 30 rebounds through the positioning frame 28.It can drive the pressing block 31 to move downward, thereby further correcting the cable and reducing the risk of operating errors and wire damage caused by wire threading difficulties.
