The utility model provides a technical solution: a rotating traction machine, including a frame 1, two ends of the frame 1 are respectively connected with connecting shaft heads 4 through bearing seats 3, the center of the connecting shaft heads 4 is provided with a through hole, a rotating frame 5 is fixed between the connecting shaft heads 4, the upper end surface of the rotating frame 5 is connected with a first guide wheel assembly 61 and a second guide wheel assembly 62 through a support seat, and the lower end surface of the rotating frame 5 is connected with a third guide wheel 63 through a support seat, a rotating motor 2 is fixed on the inner wall of one end of the frame 1, a second pulley 11 is connected to the connecting shaft head 4 on the same side of the rotating motor 2, the second pulley 11 is driven to rotate by the rotating motor 2, and the rotating motor 2 drives the connecting shaft head 4 and the rotating frame 5 to rotate through the second pulley 11, thereby further rotating the guide wheel on the rotating frame 5 to realize the rotation of the cable 7, and a routing motor 12 is also fixed on the frame 1 A transmission wheel 9 is connected to the bearing on the connecting shaft head 4 on the same side of the routing motor 12, and an output pulley is fixed to the output end of the routing motor 12, and the output pulley is connected to the transmission wheel 9. A reduction box 8 is connected to the side of the second guide wheel assembly 62, and a first pulley 81 is fixed to the output end of the reduction box 8, and the first pulley 81 is connected to the transmission wheel 9. Through the power transmission of the transmission wheel 9, the torque of the routing motor 12 is transmitted to the reduction box 8, driving the second guide wheel assembly 62 to rotate, so as to realize the wire feeding of the guide wheel to the cable, and form a twisted joint through the coordination of the rotation speed of the cable 7 and the wire feeding speed of the cable 7, and the rotation speed of the rotating frame 5 and the wire feeding speed of the cable 7 are respectively controlled by the rotating motor 2 and the routing motor 12, thereby improving the speed accuracy and production accuracy, avoiding transmission errors, and ensuring the molding of high-quality cables.

[0030] The thickness of the transmission wheel 9 is greater than the sum of the thicknesses of the first pulley 81 and the output pulley, so that the belt on the first pulley 81 and the belt on the output pulley can be completely sleeved on the transmission wheel 9, thereby increasing the contact area and improving the stability of the transmission.

[0031] like Figure 2As shown, the cross-section of the rotating frame 5 is rectangular, and a third groove 58 is provided on the lower surface of the rotating frame 5. Slide rails 57 are provided on both sides of the third groove 58. The slide rails 57 are fixed on the lower surface of the rotating frame 5. The third guide wheel 63 slides on the slide rail 57. A support seat is slidably connected to the slide rail 57. The third guide wheel 63 is rotatably connected to the support seat. The third guide wheel 63 slides along the slide rail 57. A mounting seat 59 is fixed on the lower surface of the rotating frame 5. The mounting seat 59 is located on the side of the slide rail 57. The mounting seat 59 is connected to the support seat of the third guide wheel 63 through a spring 60. The third guide wheel 63 will move left and right along the slide rail 57 under the winding action of the cable 7. At the same time, the spring 60 will deform, and a reverse force will be provided to the third guide wheel 63 through the tension or elastic force of the spring 60, so as to maintain the tension of the cable 7 on the third guide wheel 63, realize automatic adjustment of the tension of the cable 7, and ensure the stability of the tension of the cable 7.

[0032] like Figure 2 and 9 As shown, the third guide wheel 63 rotates on the support seat, and the support seat slides on the slide rail 57. A wire groove 64 is provided on the surface of the third guide wheel 63. The third guide wheel 63 slides in the third groove 58 along the slide rail 57. The third guide wheel 63 can both rotate and move along the slide rail 57. Under the action of the spring 60, when the third guide wheel 63 moves left and right along the third groove 58, the spring 60 will apply an opposite force to the third guide wheel 63, thereby ensuring that the cable 7 is subjected to the pressure of the third guide wheel 63, avoiding the cable 7 from being detached from the third guide wheel 63.

[0033] like Figure 7 As shown, the first guide wheel assembly 61 is composed of two first guide wheels 611. The centers of the two first guide wheels 611 are on the same axis. Both are rotatably connected to the top of the rotating frame 5 through a support seat. A wire groove 64 is opened on the circumference of the first guide wheel 611. The two first guide wheels 611 are both wrapped with cables 7. The leads of the cables 7 are crossed, which increases the pressure between the first guide wheels 611 and the cables 7 and ensures the stability of the molding of the cables 7.

[0034] like Figure 8 As shown, the second guide wheel assembly 62 includes a second guide wheel 621, the thickness of the second guide wheel 621 is greater than that of the first guide wheel 611, and two wire grooves 64 are provided on the circumferential surface of the second guide wheel 621. One of the first guide wheels 611 and the second guide wheel 621 are connected by a belt. By utilizing the connection between the second guide wheel 621 and the first guide wheel 611, the first guide wheel 611 is driven to rotate when the second guide wheel 621 rotates, so that the cable 7 moves synchronously on the first guide wheel 611 and the second guide wheel 621, thereby ensuring the wire feeding speed of the cable 7.

[0035] The cable leading process: the cable 7 is inserted into the rotating frame 5 from the connecting shaft head 4 at one end, and enters the wire groove 64 on one of the first guide wheels 611 at the same time. The cable 7 is led to the upper end of the second guide wheel 621 through the wire groove 64, and is wound along a wire groove 64 of the second guide wheel 621, led out from the lower end of the second guide wheel 621 and led to the lower end of the other first guide wheel 611 again. The cable 7 is wound on the first guide wheel 611, led out from the upper end and led to the upper end of the second guide wheel 621 again, and led out from the side of the second guide wheel 621 to the third guide wheel 63 located below the rotating frame 5, and led out from the upper end of the third guide wheel 63 directly into another connecting shaft head 4, and led out from the connecting shaft head 4. The leading method of the cable 7 is distributed in the two wire grooves 64 on the first guide wheel 611 and the second guide wheel 621, which increases the pressure between the cable 7 and the wire groove 64 and ensures the stability of the cable 7 twisted into shape.

[0036] like Figure 5 and 6 As shown, the rotating frame 5 is provided with a first groove 55 and a second groove 56, and the first guide wheel 611 and the second guide wheel 621 are respectively embedded in the first groove 55 and the second groove 56, and the first guide wheel 611 and the second guide wheel 621 are both tangent to the straight line where the central through hole of the connecting shaft head 4 is located. The cable 7 is tangent to the guide wheel when entering or leading out of the guide wheel, which increases the pressure of the guide wheel on the cable 7 and ensures the molding stability of the cable 7.

[0037] The first mounting plate 51 is fixed on both sides of the first groove 55, the second mounting plate 53 and the reduction box mounting plate 54 are fixed on both sides of the second groove 56 respectively, the reduction box 8 is connected to the reduction box mounting plate 54, and the first guide wheel 611 and the second guide wheel 621 are fixed respectively by the first mounting plate 51 and the second mounting plate 53, so that the first guide wheel 611 and the second guide wheel 621 are easy to install, and the reduction box 8 is installed through the reduction box mounting plate 54, which improves the installation efficiency.
