Description

Technical Field

[0001] This invention relates to the field of high-speed stranded conductor technology, and more specifically to a bow-shaped stranding device for high-speed stranded conductors. Background Technology

[0002] High-speed stranded conductors are a technology used in wire and cable manufacturing. It involves using a high-speed stranding machine to strand multiple conductors together at high speed and precision to form cable cores of the required specifications. This technology can improve production efficiency while maintaining or improving the electrical performance and mechanical strength of the cable.

[0003] In the existing technology, high-speed stranding machines mainly consist of an inlet shaft, a rotating shaft, a motor, a stranding reel, and a feeding structure. The wires and cables enter the stranding reel through the inlet shaft. The rotating shaft is driven to rotate by the motor, and the rotating shaft drives the stranding reel to rotate. The stranding reel rotates and twists the wires and cables into a single strand, which is then wound up by the feeding structure.

[0004] However, when the motor drives the stranding reel to strand the wires and cables through the rotating shaft, the stranding reel can only strand one end of the wires and cables. When a large number of wires and cables need to be stranded, the production efficiency of the stranding reel is low, which affects the performance of the high-speed stranding machine. Summary of the Invention

[0005] The purpose of this invention is to provide a bow-shaped stranding device for high-speed stranding of conductors, so as to solve the technical problem that the stranding reel can only strand wires at one end of the wire or cable in the prior art, which leads to the low working efficiency of the high-speed stranding machine.

[0006] The technical problem to be solved by this invention can be achieved through the following technical solution:

[0007] A bow-shaped stranding device for high-speed stranding of conductors, comprising:

[0008] The chassis has support platforms fixedly connected to both ends of its top, and a main drive motor fixedly connected to the side of the chassis. The support platforms are connected to an inlet shaft, and an inlet box is fixedly connected to the side of the inlet shaft. An outlet is provided at the end of the inlet shaft away from the inlet box. The inlet shaft is connected to the main drive motor. The inlet box has a feed hole that extends through the inside of the inlet shaft. The outlet and the feed hole are interconnected.

[0009] The side plate has two sets and is fixedly connected to the side end of the inlet shaft. A coiled bow is fixedly connected between the two sets of side plates. The coiled bow is arc-shaped. Several stranded wire seats are fixedly connected at equal intervals along the length of the chassis at the bottom end of the coiled bow. The coiled bow is matched with the outlet.

[0010] The frame has a side end rotatably connected to a side plate, and a feeding assembly is fixedly connected to the frame, which cooperates with a winch.

[0011] As a further embodiment of the present invention: the main drive motor is connected to a conveyor turntable, a connecting shaft is fixedly connected to the side end of the conveyor turntable, a conveyor belt is sleeved and connected to the outer wall of the main drive motor, a connecting turntable is fixedly connected to the outer wall of the infeed shaft, the direction of the infeed shaft axis is parallel to the direction of the chassis axis, and support seats are fixedly connected to both sides of the top of the support platform, the inner wall of the support seat is rotatably connected to the infeed shaft.

[0012] As a further aspect of the present invention: the connecting turntable is provided with two sets and each is connected to both ends of the connecting shaft with a connecting belt; a plurality of positioning seats are fixedly connected to the side end of the chassis; and the inner wall of the positioning seat is rotatably connected to the connecting shaft.

[0013] As a further embodiment of the present invention: the feeding assembly includes: a pull wheel, a traction wheel, a feeding turntable, and a feeding drive motor. The feeding drive motor is fixedly connected to the side end of the frame and is connected to the feeding turntable. The feeding turntable is connected to the pull wheel and the traction wheel respectively. The end of the frame away from the feeding drive motor is rotatably connected to the pull wheel and the traction wheel respectively. The pull wheel is connected to a limit assembly.

[0014] As a further embodiment of the present invention: the limiting component includes: a guide rail, a slide block and a limiting seat, the guide rail is provided with several sets and its two ends are respectively fixedly connected to the frame, the slide block is sleeved on the guide rail, the inner wall of the slide block is slidably connected to the guide rail, and the slide block is fixedly connected to the limiting seat.

[0015] As a further aspect of the present invention: the limiting seat is arc-shaped, and a plurality of conveying turntables are provided at equal intervals on the inner wall of the limiting seat, and the two ends of the conveying turntables are respectively rotatably connected to the inner wall of the limiting seat.

[0016] As a further aspect of the present invention: the slide is connected to a laser rangefinder, and the laser rangefinder is provided in two sets and located on both sides of the guide rail respectively, and the laser rangefinder is fixedly connected to the frame.

[0017] As a further embodiment of the present invention: a controller is fixedly connected to one end of the frame away from the main drive motor, and a wire reel is connected to one end of the frame perpendicular to the length direction of the chassis. The controller is respectively connected to the main drive motor and the unloading assembly. Fixed plates are respectively abutted and connected to both ends of the wire reel, and positioning holes are respectively opened at both ends of the wire reel. The fixed plates are fixedly connected to the frame, and positioning posts are connected to the fixed plates. The positioning posts are engaged with the positioning holes.

[0018] The beneficial effects of this invention are:

[0019] 1. Insert multiple wires and cables through the feed hole in the inlet box, and then pass them out through the outlet. The wires and cables pass through the inner wall of the stranding seat fixed to the bow, where the stranding seat limits their movement. Finally, connect the wires and cables to the feeding assembly. Then, run the main drive motor, which drives the feed shaft to rotate. The feed shaft drives the side plates, which in turn drive the bow to rotate. Since the bow is located between two sets of side plates, the two sets of side plates drive both ends of the bow to rotate simultaneously. The bow rotates around the frame's axis, and the bow strands the wires and cables through the stranding seat. Because both ends of the bow carry the wires and cables, when the bow rotates one revolution, the wires and cables are equivalent to rotating two revolutions, thus improving the efficiency of stranding the wires and cables.

[0020] 2. When the bow twists the wires and cables through the fixed stranding seat, the side plate rotates around the side of the frame. The side plate transfers the support of the wire inlet shaft to the frame, ensuring that the frame is located on the top of the chassis. This ensures that the bow can rotate around the frame's axis. The shape of the bow can prevent collisions with the frame. At this time, the feeding component operates, pulling the twisted wires and cables to move, thus achieving the effect of twisting and feeding the wires and cables. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figures 1-5 As shown, a bow-shaped stranding device for high-speed stranding of conductors includes: a chassis 1, side plates 7, and a frame 11.

[0030] Support platforms 2 are fixedly connected to both ends of the top of the chassis 1. A main drive motor 21 is fixedly connected to the side of the chassis 1. An inlet shaft 5 is connected to the support platform 2. An inlet box 4 is fixedly connected to the side of the inlet shaft 5. An outlet port 6 is opened at the end of the inlet shaft 5 away from the inlet box 4. The inlet shaft 5 is connected to the main drive motor 21. The inlet box 4 has a feed hole through the inside of the inlet shaft 5. The outlet port 6 is connected to the feed hole. There are two sets of side plates 7, which are fixedly connected to the side of the inlet shaft 5. A coiled bow 8 is fixedly connected between the two sets of side plates 7. The coiled bow 8 is arc-shaped. Several stranded wire seats 15 are fixedly connected at equal intervals along the length of the chassis 1 at the bottom of the coiled bow 8. The coiled bow 8 cooperates with the outlet port 6 to pass multiple wires and cables through the feed hole of the inlet box 4, and then the multiple wires and cables are... The cable exits from the outlet 6 and passes through the inner wall of the stranding seat 15 fixed to the bow 8. The stranding seat 15 limits the movement of the cable. Finally, the cable is connected to the feeding assembly. Then, the main drive motor 21 is run, which drives the infeed shaft 5 to rotate. The infeed shaft 5 drives the side plate 7, which in turn drives the bow 8 to rotate. Since the bow 8 is located between the two sets of side plates 7, the two sets of side plates 7 drive both ends of the bow 8 to rotate simultaneously. The bow 8 rotates around the axis of the frame 11. The bow 8 strands the cable through the stranding seat 15. Since both ends of the bow 8 carry the cable, when the bow 8 rotates one revolution, the cable is equivalent to rotating two revolutions, thereby improving the efficiency of stranding the cable.

[0031] The side end of the frame 11 is rotatably connected to the side plate 7. The frame 11 is fixedly connected to the feeding assembly, which cooperates with the stranding bow 8. When the stranding bow 8 strands the wires and cables through the fixed stranding seat 15, the side plate 7 rotates around the side end of the frame 11. The side plate 7 transfers the supporting effect of the wire inlet shaft 5 to the frame 11, ensuring that the frame 11 is located on the top of the chassis 1. This ensures that the stranding bow 8 can rotate around the axis of the frame 11. The shape of the stranding bow 8 can avoid collision with the frame 11. At this time, the feeding assembly operates, and the feeding assembly pulls the stranded wires and cables to move, thereby achieving the effect of stranding and feeding the wires and cables.

[0032] In some specific implementations, the main drive motor 21 is connected to a conveyor turntable 22, and a connecting shaft 25 is fixedly connected to the side of the conveyor turntable 22. A conveyor belt 23 is sleeved and connected to the outer wall of the main drive motor 21. A connecting turntable 12 is fixedly connected to the outer wall of the infeed shaft 5. The direction of the axis of the infeed shaft 5 is parallel to the direction of the axis of the chassis 1. Support seats 3 are fixedly connected to both sides of the top of the support platform 2. The inner wall of the support seat 3 is rotatably connected to the infeed shaft 5. The connecting turntable 12 has two sets and is sleeved and connected to the two ends of the connecting shaft 25 with connecting belts 13. Several positioning devices are fixedly connected to the side of the chassis 1. The inner wall of the positioning seat 24 is rotatably connected to the connecting shaft 25. When the main drive motor 21 is running, the main drive motor 21 drives the conveyor turntable 22 to rotate via the conveyor belt 23. The conveyor turntable 22 drives the connecting shaft 25 to rotate. The connecting shaft 25 drives the connecting turntable 12 to rotate via the connecting belt 13. The connecting turntable 12 drives the feed shaft 5 to rotate. The connecting shaft 25 transmits the driving force of the main drive motor 21 to the two sets of feed shafts 5. When the connecting shaft 25 rotates, the positioning seat 24 provides a limiting support for the connecting shaft 25 to ensure the stability of the rotation of the connecting shaft 25.

[0033] In some specific implementations, the feeding assembly includes: a pull reel 9, a traction wheel 10, a feeding turntable 29, and a feeding drive motor 28. The feeding drive motor 28 is fixedly connected to the side end of the frame 11, and the feeding drive motor 28 is connected to the feeding turntable 29. The feeding turntable 29 is connected to both the pull reel 9 and the traction wheel 10. The end of the frame 11 away from the feeding drive motor 28 is rotatably connected to both the pull reel 9 and the traction wheel 10. The pull reel 9 is connected to a limit component. When the feeding assembly is running, the twisted wire / cable... The wire and cable are wound once on the pull reel 9, then once on the traction wheel 10, and then back onto the pull reel 9 for another turn. This process is repeated. When the feeding drive 28 is running, it drives the feeding turntable 29 to rotate. The feeding turntable 29 drives the pull reel 9 and the traction wheel 10 to rotate synchronously. The wire and cable are detached under the rotation of the pull reel 9 and the traction wheel 10. The limiting component controls the wire and cable to detach from the top of the pull reel 9, thereby achieving the effect of feeding the wire and cable.

[0034] In some specific implementations, the limiting component includes: a guide rail 17, a slide 18, and a limiting seat 19. The guide rail 17 has several sets of components, and both ends are fixedly connected to the frame 11. The slide 18 is sleeved on the guide rail 17, and the inner wall of the slide 18 is slidably connected to the guide rail 17. The slide 18 is fixedly connected to the limiting seat 19, which is arc-shaped. The inner wall of the limiting seat 19 has several conveying turntables 22 equidistantly arranged, and both ends of the conveying turntables 22 are rotatably connected to the inner wall of the limiting seat 19. A laser rangefinder 16 is connected to the slide 18. The laser rangefinder 16 has two sets, located on both sides of the guide rail 17, and is fixedly connected to the frame 11. When the limiting component is running, the wire and cable pass through the inner wall of the limiting seat 19. When the wire and cable are wound up, the coiled wire and cable rotates with the coiled wire and cable 8, so the wound wire and cable can be automatically wound up. The slide 18 can be driven by a motor using existing technology. The slide 18 moves along the guide rail 17, and the slide 18 moves the limiting seat 19 along with it. Thus, the limiting seat 19 can move the wire and cable in different horizontal directions, thereby ensuring the uniformity of the wire and cable winding. When the wire and cable passes through the inner wall of the limiting seat 19, the wire and cable moves along the limiting wheel 20. The limiting wheel 20 rotates as the wire and cable moves, which can limit the wire and cable and at the same time prevent the wire and cable from sliding on the inner wall of the limiting seat 19 and generating large friction. When the slide 18 moves, the laser rangefinder 16 can measure the distance that the slide 18 moves. The laser rangefinder 16 transmits the measured signal to the motor, thereby controlling the distance that the slide 18 moves according to the number of rotations of the bow 8 when the wire and cable is wound.

[0035] In some specific implementations, a controller 27 is fixedly connected to the end of the frame 11 away from the main drive motor 21, and a wire reel 26 is connected to the end of the frame 11 perpendicular to the length direction of the chassis 1. The controller 27 cooperates with the main drive motor 21 and the feeding assembly. Fixed plates 14 are respectively abutted and connected to both ends of the wire reel 26. Positioning holes are opened at both ends of the wire reel 26. The fixed plates 14 are fixedly connected to the frame 11, and positioning posts 30 are connected to the fixed plates 14. The positioning posts 30 cooperate with the positioning holes. When the wire and cable are wound, the wire and cable are wound and stored on the wire reel 26. When the wire reel 26 has finished winding the wire and cable, the positioning posts 30 can be controlled by a cylinder of the prior art. The cylinder controls the positioning posts 30 to lock into the fixed plates 14. At this time, the positioning posts 30 disengage from the positioning holes, releasing the positioning function of the wire reel 26. The operator can control the controller 27 to adjust the power of the main drive motor 21 and the feeding assembly, further improving the applicability of the bow 8 to wire and cable strands.

All equivalent variations and improvements made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
