Description

Technical Field

[0001] This invention relates to stranding machines, and more specifically to a bow-shaped stranding machine. Background Technology

[0002] A stranding machine is a type of mechanical equipment widely used for stranding various soft and hard conductor wires. It can twist multiple single conductors into a single strand to meet the process requirements of wire. Common stranding machines can be classified according to the stranding method into single stranding machines, double stranding machines, high-speed stranding machines, untwisting machines, cage stranding machines, frame stranding machines, tubular stranding machines, and disc stranding machines. The wires produced by these machines are widely used in various aspects of modern society, such as power and communications.

[0003] For example, Chinese invention application CN119274885A discloses a ship-frame cradle structure stranding machine. This stranding machine includes a housing, a rotation control mechanism, and a take-up frame. The rotation control mechanism is rotatably mounted inside the housing and includes two symmetrically arranged bows. The bows allow the wire to pass through and be stranded. The take-up frame is rotatably connected inside the rotation control mechanism and has a spool rotatably mounted on it. The take-up frame also includes a wire-laying mechanism, comprising a first guide wheel, a second guide wheel, a third guide wheel, a fourth guide wheel, and a wire lay-up device on the left side of the take-up frame. The fourth guide wheel is mounted on the wire lay-up device. The four guide wheels of the take-up frame are distributed along the long axis diameter of the bows, and the take-up frame and the spool are also distributed along the long axis diameter of the bows. This invention effectively shortens the short axis diameter of the bows, thereby shortening the rotation radius of the stranding machine, avoiding excessive centrifugal force, and ultimately reducing machine vibration and noise.

[0004] The above-mentioned stranding machine has the following shortcomings: The existing stranding machine is equipped with a main drive motor. The output shaft of the main drive motor is connected to the right threading shaft to drive its rotation. A coupling mechanism connects the left and right ordinary threading shafts, allowing the main drive motor to synchronously drive both shafts. However, because the main drive motor is located on the outside of the machine casing, it requires additional space, resulting in a less compact structure and a larger size, which needs improvement. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned problems and provide a bow-shaped stranding machine, which has the advantages of compact structure and small size.

[0006] The objective of this invention is achieved through the following technical solution: A bow-shaped stranding machine includes a chassis and a ship-frame type rotating mechanism and a rotating drive mechanism disposed within the chassis. The ship-frame type rotating mechanism includes an inlet-side bearing housing assembly, an outlet-side bearing housing assembly, a stranding bow, a take-up frame, and an outlet stranding mechanism. The rotary drive mechanism includes a rotary drive motor and a rotary transmission assembly. The rotary drive motor is disposed on the axial side of the inlet-side bearing housing assembly. The rotary transmission assembly includes an inlet-side transmission assembly, an outlet-side transmission assembly, and a synchronous linkage assembly. The synchronous linkage assembly is connected between the inlet-side transmission assembly and the outlet-side transmission assembly. The synchronous linkage assembly includes a synchronous linkage transmission shaft, and the rotary drive motor is located above the first end of the synchronous linkage transmission shaft.

[0007] In a preferred embodiment of the present invention, the lead-out cable laying mechanism is mounted on the take-up frame. This mechanism includes a lead-out traction mechanism and a dynamic cable laying mechanism. The lead-out traction mechanism comprises a lead-out traction assembly and a lead-out traction drive mechanism. The lead-out traction assembly includes an upper lead-out traction wheel, a lower lead-out traction wheel, and a lead-out guide wheel. The axis of the upper lead-out traction wheel is parallel to the axis of the lower lead-out traction wheel, and the axis of the upper lead-out traction wheel is parallel to the lateral movement direction of the lead-out traction assembly. With this structure, the lead-out traction mechanism can stably pull the stranded wire from the coiled wire area. The upper and lower lead-out traction wheels cooperate to form a stable traction force, ensuring the continuity of wire delivery.

[0008] Furthermore, the outgoing line traction drive mechanism includes an outgoing line traction drive motor and an outgoing line traction transmission assembly. The outgoing line traction transmission assembly includes a synchronous belt and a synchronous pulley, which are connected between the outgoing line traction drive motor and the lower outgoing line traction pulley.

[0009] Furthermore, the dynamic cable laying mechanism includes a dynamic cable laying assembly and a lateral drive mechanism for driving the dynamic cable laying assembly to move laterally. The dynamic cable laying assembly includes a cable laying mounting base, a cable laying eye, a cable laying guide wheel, and a fixed guide wheel. The cable laying guide wheel is mounted on the cable laying mounting base via a first swing structure, and is located on the side of the cable laying mounting base closer to the cable output traction mechanism. The cable laying eye is connected to the first swing structure via a second swing structure, and is located above the cable output guide wheel. The fixed guide wheel is rotatably mounted on the cable laying mounting base, and is located on the side of the cable laying mounting base closer to the take-up drum. With the above structure, the dynamic cable laying mechanism can move laterally reciprocally under the drive of the lateral drive mechanism, so that the cable is evenly distributed on the take-up drum.

[0010] Furthermore, the lateral drive mechanism includes a lateral drive motor and a lateral transmission assembly. The lateral transmission assembly includes a lateral lead screw and a lateral lead screw nut, and the lateral lead screw nut is fixedly connected to the cable mounting base.

[0011] Furthermore, the dynamic cable routing mechanism also includes a cable routing sway adaptive module. This cable routing sway integrated module includes an integrated mounting plate and stabilizing cable routing wheels. The integrated mounting plate is directly or indirectly connected to the cable routing mounting base. Two stabilizing cable routing wheels are provided and arranged horizontally and parallel to each other. The stabilizing cable routing wheels are directly or indirectly rotatably connected to the integrated mounting plate. The stabilizing cable routing wheels are located between the cable routing ceramic eye and the cable exit guide wheel. The axis of the stabilizing cable routing wheel is perpendicular to the axis of the cable routing ceramic eye and the axis of the cable exit guide wheel, respectively. The axis of the stabilizing cable routing wheel is parallel to the lateral movement direction of the cable exit traction component and parallel to the axis of the cable exit guide wheel. A cable routing gap is provided between the two stabilizing cable routing wheels, and the axis of the cable routing ceramic eye passes through the cable routing gap. With the above structure, in actual stranding operations, the stranded wire is pulled out by the upper and lower lead-out traction wheels, then guided by the lead-out guide wheel to the upper stable guide wheel. After passing through the gap between the two stable guide wheels, it enters the wire guide ceramic eye directly, then winds around the guide wheel to the fixed guide wheel, and finally is wound up by the take-up drum. In this process, firstly, because the axis of the lead-out guide wheel is parallel to the lateral movement direction of the lead-out traction assembly (i.e., the axis of the lead-out guide wheel is perpendicular to the lateral movement direction of the lead-out traction assembly), when the lead-out traction assembly moves, the stranded wire will not deviate axially from the lead-out guide wheel, but will adaptively adjust in the circumferential direction of the lead-out guide wheel, which helps to ensure a more accurate and stable lead-out path. Furthermore, since the axis of the stabilizing cable guide wheel is parallel to the axis of the output guide wheel, when the cable gap is located exactly in the middle of the output guide wheel and the cable tray eye, the stranded wire, after being guided by the output guide wheel, will pass directly through the cable gap between the two stabilizing cable guide wheels. The stranded wire will not undergo reversal of direction by the stabilizing cable guide wheels. At this time, the bending part is minimized, and the cable delivery is smoothest. When the cable gap is not located exactly in the middle of the output guide wheel and the cable tray eye, for example, when the output traction assembly moves laterally to the left, the stranded wire will first wrap around the underside of the stabilizing cable guide wheel located on the right, then enter the cable gap along the circumference of the stabilizing cable guide wheel, and finally be delivered directly to the cable tray guide wheel. Similarly, when the output traction assembly moves laterally to the right, the stranded wire will first wrap around the underside of the stabilizing cable guide wheel located on the left, then enter the cable gap along the circumference of the stabilizing cable guide wheel. Therefore, the stabilizing guide wheel in this design acts as an intermediate reversing mechanism, providing a relatively smooth turn throughout the entire lateral movement of the lead-out traction component and guiding the stranded wire into the guide gap. During this process, the stranded wire will not rotate sharply, which can effectively reduce the pulling force (friction) and prevent the stranded wire from being subjected to additional pulling, thus improving the quality of the stranded wire.

[0012] Furthermore, the first swing structure includes a first swing mounting frame and a counterweight. The first swing mounting frame rotatably passes through the cable mounting base. One end of the first swing mounting frame is rotatably connected to the cable guide wheel, and the other end is fixedly connected to the counterweight. The rotation center of the first swing mounting frame is perpendicular to the axis of the cable guide wheel. Through this structure, the counterweight ensures that the first swing mounting frame maintains a stable posture under gravity. When the cable tension changes, the cable guide wheel can adaptively swing and adjust, ensuring good guidance of the cable by the cable guide wheel. The structure is simple and reliable.

[0013] Furthermore, the second swing structure includes a second swing mounting bracket and a screw locking structure. The second swing mounting bracket is rotatably connected to the first swing mounting bracket of the first swing structure, which has an arc-shaped adjustment groove. With the rotation center of the second swing mounting bracket as the boundary, one end of the second swing mounting bracket is fixedly connected to the ribbon cable eye, and the other end of the second swing mounting bracket is locked through the arc-shaped adjustment groove by the screw locking structure. With this structure, after loosening the screw locking structure, the second swing mounting bracket can be swinged up and down, thereby adjusting the posture of the ribbon cable eye to adapt to different ribbon cable path requirements, offering good flexibility.

[0014] Furthermore, the cable routing sway integrated module includes an integrated sway mounting base, an integrated sway frame, and a sway limiting pusher. Two integrated sway mounting bases are provided and fixedly mounted on the cable mounting base. One end of the integrated sway frame is rotatably connected to the two integrated sway mounting bases. The integrated sway frame is provided with two sliding mounting rods, and each of the two sliding mounting rods is provided with an axial sliding rail. Two stabilizing cable routing wheels are respectively mounted on the two sliding mounting rods through bearings. The inner rings of the two bearings are provided with axial sliding grooves. Two sway limiting pushers are provided and arranged opposite to each other. One end of the sway limiting pusher is movably connected to one end of the second swing mounting bracket along the axial direction of the cable tray eye. The other end of the sway limiting pusher is a bidirectional limiting structure that extends in the direction of the sliding mounting rod. The bidirectional limiting structure is located outside the two end faces of the stabilizing cable tray. The bidirectional limiting structure is used to control the axial movement of the corresponding stabilizing cable tray. The inner wall of the bidirectional limiting structure is provided with a guide support groove, which cooperates with the sliding mounting rod. The guide support groove is a semi-circular or slightly curved structure, and the openings of the guide support grooves of the two swing limiting pushers face each other. The bidirectional limiting structure is provided with a bottom reinforcing crossbeam at its end, which is located below the sliding mounting rod. The bottom reinforcing crossbeams of the two swing limiting pushers are arranged vertically, with the end of the bottom reinforcing crossbeam of one swing limiting pusher abutting against the end of the bidirectional limiting structure of the other swing limiting pusher. The two bottom reinforcing crossbeams are fixed together by screws.

[0015] With the above structure, when the posture of the ribbon cable eye is adjusted, the posture of the stabilizing wheel will be adjusted synchronously to ensure that the axis of the ribbon cable eye can pass straight through the cable gap. Specifically, when the second swing mounting frame swings, the two sway limit pushers perform a compound linkage operation simultaneously: on the one hand, the guide support groove of the bidirectional limit structure carries the sliding mounting rod to swing synchronously, so that the entire integrated sway frame and the stabilizing wheel swing in the same direction, ensuring that the axis of the stabilizing wheel is relatively perpendicular to the axis of the ribbon cable eye, realizing the adaptive adjustment of the posture of the stabilizing wheel, so as to more accurately and smoothly transport and guide the stranded wire; on the other hand, when the sway limit pusher swings, its bidirectional limit structure will push the stabilizing wheel in the corresponding direction, so that the stabilizing wheel moves axially to the designated position, so that the cable gap is located on the axis of the ribbon cable eye, automatically realizing the dynamic consistency adjustment of the posture and position of the stabilizing wheel, ensuring the smoothness of the cable after adjustment, which is very convenient. In addition, by setting a bottom reinforcing crossbeam, the support of the two sliding mounting rods can be strengthened to prevent the bottom from slipping off, and the rigidity of the sway limit pusher can be improved.

[0016] Furthermore, the integrated mounting plate is provided with a synchronous swing arc-shaped hole, within which a synchronous swing pin fixed to the cable mounting base is disposed. The center of the synchronous swing arc-shaped hole is collinear with the rotation center of the first swing mounting frame. Through this structure, the entire cable routing yaw integrated module can swing along with the swing of the first swing mounting frame, adaptively adjusting its posture in the other direction, further achieving dynamic consistency adjustment of posture – a truly ingenious design! Compared with the prior art, the present invention has the following advantages: 1. By placing the rotary drive motor on the axial side of the inlet bearing housing assembly and positioning it above the beginning of the synchronous linkage transmission shaft, the present invention effectively optimizes the spatial layout of the entire machine, avoids the problem of increased volume caused by placing the traditional drive motor externally in the chassis, and makes the overall structure more compact and occupies less space.

[0017] 2. Because the rotary drive motor is embedded inside the chassis and rationally arranged with the synchronous linkage components, the machine maintains high-efficiency transmission performance while significantly reducing the footprint of the machine, making it easier to install and operate in limited spaces, and improving the applicability and flexibility of the equipment.

The rotating transmission assembly includes an inlet-side transmission assembly, an outlet-side transmission assembly, and a synchronous linkage assembly. The synchronous linkage assembly is connected between the inlet-side transmission assembly and the outlet-side transmission assembly. The synchronous linkage assembly includes a synchronous linkage transmission shaft, and the rotating drive motor 5 is located above the first end of the synchronous linkage transmission shaft. Specifically, the specific structure of the rotating drive mechanism of this embodiment can be referred to the prior art.

[0028] Combination Figure 3The cable delivery mechanism is mounted on the take-up frame 4. This mechanism includes a cable delivery traction mechanism and a dynamic cable delivery mechanism. The cable delivery traction mechanism comprises a cable delivery traction assembly and a cable delivery traction drive mechanism. The cable delivery traction assembly includes an upper cable delivery traction wheel 6, a lower cable delivery traction wheel 7, and a cable delivery guide wheel 8. The axis of the upper cable delivery traction wheel 6 is parallel to the axis of the lower cable delivery traction wheel 7, and the axis of the upper cable delivery traction wheel 6 is parallel to the lateral movement direction of the cable delivery traction assembly. Through this structure, the cable delivery traction mechanism can stably pull the stranded wire from the coiled wire area 3. The upper cable delivery traction wheel 6 and the lower cable delivery traction wheel 7 work together to form a stable traction force, ensuring the continuity of wire delivery.

[0029] Furthermore, the outgoing line traction drive mechanism includes an outgoing line traction drive motor and an outgoing line traction transmission assembly. The outgoing line traction transmission assembly includes a synchronous belt 9 and a synchronous pulley 10, which are connected between the outgoing line traction drive motor and the lower outgoing line traction pulley 7. Specifically, the specific structure of the outgoing line traction drive mechanism in this embodiment can be found in the prior art.

[0030] Combination Figures 3-4 The dynamic cable laying mechanism includes a dynamic cable laying assembly and a lateral drive mechanism for driving the dynamic cable laying assembly to move laterally. The dynamic cable laying assembly includes a cable laying mounting base 11, a cable laying eye 12, a cable laying guide wheel 13, and a fixed guide wheel 14. The cable laying guide wheel 13 is mounted on the cable laying mounting base 11 via a first swing structure, and is located on the side of the cable laying mounting base 11 closer to the cable output traction mechanism. The cable laying eye 12 is connected to the first swing structure via a second swing structure, and is located above the cable output guide wheel 8. The fixed guide wheel 14 is rotatably mounted on the cable laying mounting base 11, and is located on the side of the cable laying mounting base 11 closer to the take-up drum. With the above structure, the dynamic cable laying mechanism can move laterally back and forth under the drive of the lateral drive mechanism, so that the cable is evenly distributed on the take-up drum.

[0031] Furthermore, the lateral drive mechanism includes a lateral drive motor 15 and a lateral transmission assembly. The lateral transmission assembly includes a lateral lead screw and a lateral lead screw nut, and the lateral lead screw nut is fixedly connected to the cable mounting base 11. Specifically, the specific structure of the lateral drive mechanism in this embodiment can be found in the prior art.

[0032] Combination Figures 3-4The first swing structure includes a first swing mounting frame 16 and a counterweight 17. The first swing mounting frame 16 rotatably passes through the cable mounting base 11. One end of the first swing mounting frame 16 is rotatably connected to the cable guide wheel 13, and the other end is fixedly connected to the counterweight 17. The rotation center of the first swing mounting frame 16 is perpendicular to the axis of the cable guide wheel 13. Through this structure, the counterweight 17 ensures that the first swing mounting frame 16 maintains a stable posture under gravity. When the cable tension changes, the cable guide wheel 13 can adaptively swing and adjust, ensuring good guiding effect of the cable guide wheel 13 on the cable. The structure is simple and reliable.

[0033] Combination Figures 3-4 The second swing structure includes a second swing mounting bracket 18 and a screw locking structure. The second swing mounting bracket 18 is rotatably connected to the first swing mounting bracket 16 of the first swing structure. The first swing mounting bracket 16 of the first swing structure is provided with an arc-shaped adjustment groove. Taking the rotation center of the second swing mounting bracket 18 as the boundary, one end of the second swing mounting bracket 18 is fixedly connected to the ribbon cable eye 12, and the other end of the second swing mounting bracket 18 is locked through the arc-shaped adjustment groove by the screw locking structure. With the above structure, after loosening the screw locking structure, the second swing mounting bracket 18 can be swung up and down, thereby adjusting the posture of the ribbon cable eye 12 to adapt to different ribbon cable path requirements, providing good flexibility.

[0034] Combination Figures 4-7The dynamic cable routing mechanism further includes a cable routing sway adaptive module. This cable routing sway integrated module includes an integrated mounting plate 19 and stabilizing cable routing wheels 20. The integrated mounting plate 19 is directly or indirectly connected to the cable routing mounting base 11. Two stabilizing cable routing wheels 20 are provided and arranged horizontally and parallel to each other. The stabilizing cable routing wheels 20 are directly or indirectly rotatably connected to the integrated mounting plate 19. The stabilizing cable routing wheels 20 are located between the cable routing ceramic eye 12 and the cable exit guide wheel 8. The axis of the stabilizing cable routing wheels 20 is perpendicular to the axis of the cable routing ceramic eye 12 and the axis of the cable routing guide wheel 13, respectively. The axis of the stabilizing cable routing wheels 20 is parallel to the lateral movement direction of the cable exit traction assembly and parallel to the axis of the cable exit guide wheel 8. A cable routing gap is provided between the two stabilizing cable routing wheels 20, and the axis of the cable routing ceramic eye 12 passes through the cable routing gap. With the above structure, in actual stranding operation, the stranded wire is pulled out by the upper lead-out traction wheel 6 and the lower lead-out traction wheel 7, then guided by the lead-out guide wheel 8 to the upper stable guide wheel 20. After passing through the wire gap between the two stable guide wheels 20, it directly enters the wire guide eye 12, then winds around the fixed guide wheel 14 via the wire guide wheel 13, and finally is wound up by the take-up drum. In the above process, firstly, since the axis of the lead-out guide wheel 8 is parallel to the lateral movement direction of the lead-out traction assembly, that is, the axis of the lead-out guide wheel 8 is perpendicular to the lateral movement direction of the lead-out traction assembly, when the lead-out traction assembly moves, the stranded wire will not deviate axially from the lead-out guide wheel 8, but will adaptively adjust in the circumferential direction of the lead-out guide wheel 8, which helps to ensure a more accurate and stable lead-out path. Furthermore, since the axis of the stable guide wheel 20 is parallel to the axis of the lead-out guide wheel 8, when the wire gap is located in the middle between the lead-out guide wheel 8 and the wire guide eye 12, such as Figure 5 After being guided by the lead-out guide wheel 8, the stranded wire will pass directly through the wire feeding gap between the two stabilizing wire feeding wheels 20. The stranded wire will not be reversed by the stabilizing wire feeding wheels 20. At this time, the bending part is minimized and the wire feeding is smoothest. When the wire feeding gap is not located in the exact middle between the lead-out guide wheel 8 and the wire guide eye 12, for example, when the lead-out traction component moves laterally to the left, the stranded wire will first wrap around the bottom of the stabilizing wire feeding wheel 20 located on the right, and then enter the wire feeding gap along the circumference of the stabilizing wire feeding wheel 20. Figure 6 Finally, it is directly conveyed to the cable guide wheel 13. Similarly, when the cable traction assembly moves laterally to the right, the stranded wire will first wrap around below the stabilizing cable guide wheel 20 located on the left, such as... Figure 7The stranded wire then follows the circumference of the stabilizing guide wheel 20 into the wire routing gap. Thus, the stabilizing guide wheel 20 in this design acts as an intermediate reversing mechanism, providing a relatively smooth turn throughout the entire lateral movement of the lead-out traction component, guiding the stranded wire into the routing gap. During this process, the stranded wire does not undergo sharp turns, effectively reducing tensile force (friction) and preventing additional tension on the stranded wire, thereby improving its quality.

[0035] Combination Figures 8-11 The cable routing sway integrated module includes an integrated sway mounting base 21, an integrated sway frame 22, and a sway limiting pusher 23. Two integrated sway mounting bases 21 are provided and fixedly mounted on the cable mounting base 11. One end of the integrated sway frame 22 is rotatably connected to the two integrated sway mounting bases 21. The integrated sway frame 22 is provided with two sliding mounting rods 22-1. Each of the two sliding mounting rods 22-1 is provided with an axial sliding rail 22-2. Two stabilizing cable routing wheels 20 are respectively mounted on the two sliding mounting rods 22-1 through bearings. The inner rings of the two bearings are provided with axial sliding grooves.

[0036] Two sway limiting pushers 23 are provided and arranged opposite to each other. One end of the sway limiting pusher 23 is movably connected to one end of the second swing mounting bracket 18 along the axial direction of the cable tray eye 12. The other end of the sway limiting pusher 23 is a bidirectional limiting structure and extends in the direction of the sliding mounting rod 22-1. The bidirectional limiting structure is located outside the two end faces of the stabilizing cable tray 20. The bidirectional limiting structure is used to control the axial movement of the corresponding stabilizing cable tray 20.

[0037] The inner wall of the bidirectional limiting structure is provided with a guide support groove 23-1, which cooperates with the sliding mounting rod 22-1. The guide support groove 23-1 is a semi-circular or slightly curved structure, and the openings of the guide support grooves 23-1 of the two swing limiting pushers 23 face each other.

[0038] The end of the bidirectional limiting structure is provided with a bottom reinforcing crossbeam 23-2, which is located below the sliding mounting rod 22-1. The bottom reinforcing crossbeams 23-2 of the two swing limiting pushers 23 are arranged vertically. The end of the bottom reinforcing crossbeam 23-2 of one swing limiting pusher 23 rests on the end of the bidirectional limiting structure of the other swing limiting pusher 23. The two bottom reinforcing crossbeams 23-2 are fixed together by screws.

[0039] With the above structure, when the posture of the ribbon cable eye 12 is adjusted, the posture of the stabilizing cable wheel 20 will be adjusted synchronously to ensure that the axis of the ribbon cable eye 12 can pass straight through the cable gap. Specifically, when the second swing mounting bracket 18 swings, the two swing limit pushers 23 perform a compound linkage operation simultaneously: on the one hand, the guide support groove 23-1 of the bidirectional limit structure drives the sliding mounting rod 22-1 to swing synchronously, so that the entire integrated swing bracket 22 and the stabilizing cable wheel 20 swing in the same direction. Ensuring that the axis of the stabilizing guide wheel 20 is perpendicular to the axis of the ribbon cable eye 12 enables adaptive adjustment of the stabilizing guide wheel 20's posture, allowing for more precise and smooth wire feeding and guidance. On the other hand, when the sway limit pusher 23 oscillates, its bidirectional limit structure pushes the stabilizing guide wheel 20 in the corresponding direction, causing the stabilizing guide wheel 20 to move axially to a designated position, ensuring the wire gap is aligned with the axis of the ribbon cable eye 12. This automatically achieves dynamic consistency adjustment of the stabilizing guide wheel 20's posture and position. Figure 8-9 This ensures smooth wiring after adjustment and is very convenient. In addition, by setting the bottom reinforcing crossbeam 23-2, the support of the two sliding mounting rods 22-1 can be strengthened to prevent bottoming out and improve the rigidity of the sway limit pusher 23.

[0040] Furthermore, the integrated mounting plate 19 is provided with a synchronous swing arc-shaped hole 19-1, in which a synchronous swing pin 24 fixed to the cable mounting base 11 is disposed. The center of the synchronous swing arc-shaped hole 19-1 is collinear with the rotation center of the first swing mounting frame 16. Through the above structure, the entire cable routing sway integrated module can swing with the swing of the first swing mounting frame 16, adaptively completing the attitude adjustment in another direction, further realizing dynamic consistency adjustment of attitude, which is very ingenious! Combination Figures 1-4 The working principle of the above-mentioned bow-shaped stranding machine is as follows: During operation, the rotary drive motor 5 is started, driving the boat-frame rotary mechanism to rotate via the rotary transmission assembly. The bow 3 rotates with the boat-frame rotary mechanism, twisting the wire passing through the bow 3. The twisted wire enters the take-up frame 4, where it is laid out and wound up by the wire laying mechanism. Specifically, the upper wire laying traction wheel 6 and the lower wire laying traction wheel 7 in the wire laying traction mechanism pull out the stranded wire, which is then guided by the wire laying guide wheel 8 and enters the dynamic wire laying mechanism. In the dynamic wire laying mechanism, the wire laying eye 12, the wire laying guide wheel 13, and the fixed guide wheel 14 jointly guide the stranded wire and move laterally under the drive of the lateral drive mechanism, so that the stranded wire is evenly distributed on the take-up drum.

[0041] When the outgoing traction mechanism moves laterally, the stabilizing wire wheel 20 in the wire routing sway adaptive module plays an intermediate reversing role, ensuring that the stranded wire remains smooth before entering the wire guide eye 12, avoiding sudden turns and pulling; at the same time, the first swing structure and the second swing structure can adjust the posture of the wire guide wheel 13 and the wire guide eye 12 according to the wire routing requirements, making the stranded wire path more flexible and adaptable.

[0042] In summary, this invention achieves stable operation and high-quality wire laying in the stranding process through the built-in arrangement of the rotary drive motor 5, synchronous linkage transmission, and the coordinated work of the dynamic wire laying mechanism. The whole machine has a compact structure, small size, and stable operation.
