Description

Technical Field

[0001] This utility model relates to the field of stranding machine technology, specifically to a stranding device for an automatic high-speed stranding machine. Background Technology

[0002] A stranding machine is a specialized mechanical device used to strand multiple conductors together. It is widely used in power, telecommunications, and railway industries, primarily to improve the tensile strength, anti-interference ability, and wear resistance of conductors, thereby ensuring the safety and stability of cables during long-term use. Structurally, a stranding machine mainly consists of an infeed device, a stranding device, a drive system, a control system, and a take-up device. The infeed device is responsible for guiding the raw materials into the stranding machine, ensuring the conductors smoothly enter the stranding area. The stranding device is its core component, typically composed of multiple stranding wheels and a stranding shaft. The rotation of the wheels causes the conductors to be stranded under a certain tension. The drive system consists of an electric motor, a reducer, and a transmission device, providing the necessary power for the stranding process. For example, the stranding device of an automatic high-speed stranding machine disclosed in patent announcement number CN212434342U includes a base. Two first mounting plates are symmetrically fixedly mounted on the top of the base. A second mounting plate is fixedly mounted on each of the two first mounting plates. A third mounting plate is slidably mounted on the bottom of each of the two second mounting plates. Rotating rods are rotatably mounted on each of the two third mounting plates. Fixing plates are fixedly mounted on each of the two rotating rods. Screws are threaded onto each of the two fixing plates. Pressure plates are fixedly mounted at the bottom ends of each of the two screws. During the stranding process, the clamping device changes its spacing to ensure that the raw material is not further stranded. Damage can occur during the stranding process, and after the stranding is completed and no longer clamped, the clamping device will reset, allowing the finished stranded wire to fall onto the receiving plate. However, the above technical solution is mainly suitable for stranding short-length wires. For the stranding of long-specification wires, it is difficult to simultaneously complete the stranding and subsequent winding operations. That is, at least two drive devices are required as power sources. Moreover, the stranding speed and winding speed required for long wires often differ significantly. If the stranding speed is too fast and the winding speed is too slow, the wire may accumulate in the stranding area, increasing the equipment load and even causing equipment damage. Conversely, if the winding speed is too fast, the stranded wire may become loose, resulting in poor stranding effect. Utility Model Content

[0003] The purpose of this utility model is to provide a stranding device for an automatic high-speed stranding machine. The wire to be stranded passes through the wire feed drum of the turntable. The wire that has been initially stranded is wound onto the stranding take-up mechanism. At this time, the gear drive unit drives the turntable to rotate, and multiple wire feed drums rotate around the turntable to form stranded wire. The rotational power of the gear drive unit is transmitted to the stranding take-up mechanism through the pulley transmission structure and the worm gear transmission structure to simultaneously complete the wire stranding and stranding take-up operations, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a stranding device for an automatic high-speed stranding machine, comprising a right-angle frame and a stranding winding mechanism disposed on one side of the right-angle frame. A turntable is rotatably mounted on the top of the right-angle frame, and several corresponding and interconnected wire guides are mounted on the outer walls of both sides of the turntable. A gear drive unit for driving the turntable to rotate is mounted on one outer wall of the right-angle frame. A horizontal shaft is rotatably mounted on the outer wall of the right-angle frame near the stranding winding mechanism. A pulley transmission structure for maintaining power transmission is installed between the horizontal shaft and the gear drive unit. A worm gear transmission structure for driving the stranding winding mechanism is mounted on the other end of the horizontal shaft.

[0005] Preferably, the strand winding mechanism includes a frame fixed to one side of the outer wall of the right-angle frame, bearing seats fixed on both sides of the top of the frame, a driven shaft rotatably mounted between the two bearing seats, and a drum fixed to the outer circumference of the driven shaft.

[0006] Preferably, the worm gear transmission structure includes a worm fixed to one end of the horizontal shaft and a worm wheel fixed to one end of the driven shaft surface, with the worm and worm wheel meshing with each other.

[0007] Preferably, the gear drive unit includes a stepper motor mounted on one side of the outer wall of the right-angle frame, a primary gear mounted on the output end of the stepper motor, and a central shaft rotatably mounted on the other side of the outer wall of the right-angle frame. One end of the surface of the central shaft is fixed with a secondary gear that meshes with the primary gear. A gear ring for meshing with the secondary gear is fixed on the outer wall of the turntable near the strand winding mechanism. The pulley drive structure is mounted on the output end of the stepper motor.

[0008] Preferably, several of the cable trays are located inside the toothed ring, and the cable trays are made of stainless steel.

[0009] Preferably, wheel frames are fixed on both the front and rear outer walls of the right-angle frame, and support wheels are rotatably installed inside the wheel frames, with the support wheels and the turntable in contact with each other.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The stranding device of this automatic high-speed stranding machine achieves efficient and stable completion of the stranding and winding process of the cable through the coordinated work of a right-angle frame, a turntable, a cable guide drum, a gear drive unit, a pulley transmission structure, a worm gear transmission structure, and a stranding winding mechanism. The gear drive unit drives the turntable to rotate, and multiple cable guide drums rotate around the turntable together, thus achieving synchronous stranding. The gear transmission structure can precisely control the speed and synchronicity of each link, avoiding the problem of mismatch between stranding and winding speeds in traditional stranding machines. Furthermore, through the cooperation of the pulley transmission structure and the worm gear transmission structure, the stranding winding mechanism can complete the stranding and winding operations simultaneously. Therefore, by utilizing mechanical transmission and control, the stranding and winding tasks can be completed within the same work cycle, greatly improving production efficiency.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] Please see Figure 1-5The present invention provides an embodiment of a stranding device for an automatic high-speed stranding machine, comprising a right-angle frame 1 and a stranding winding mechanism 3 provided on one side of the right-angle frame 1. A turntable 4 is rotatably mounted on the top of the right-angle frame 1, and several corresponding and interconnected wire guides 5 are installed on the outer walls of both sides of the turntable 4. The right-angle frame 1 and the frame 2 are used to support and fix other components of the device to ensure the stability of the entire stranding structure.

[0019] A gear drive unit 6 for driving the turntable 4 to rotate is installed on one outer wall of the right-angle frame 1. A horizontal shaft 9 is rotatably installed on the outer wall of the right-angle frame 1 near the strand winding mechanism 3. A belt drive structure 11 for maintaining power transmission is installed between the horizontal shaft 9 and the gear drive unit 6. A worm gear drive structure 10 for driving the strand winding mechanism 3 is installed at the other end of the horizontal shaft 9.

[0020] Wheel frames 7 are fixed on the front and rear outer walls of the right-angle frame 1, and support wheels 8 are rotatably installed inside the wheel frames 7. The support wheels 8 and the turntable 4 are in contact with each other, and the rotational stability of the wheel frames 7 is improved by the support wheels 8.

[0021] The gear drive unit 6 includes a stepper motor 601 mounted on one side of the outer wall of the right-angle frame 1, a first-stage gear 605 mounted on the output end of the stepper motor 601, and a central shaft 602 rotatably mounted on the other side of the outer wall of the right-angle frame 1. A second-stage gear 604 that meshes with the first-stage gear 605 is fixed at one end of the surface of the central shaft 602. A gear ring 603 that meshes with the second-stage gear 604 is fixed on the outer wall of the turntable 4 near the strand winding mechanism 3. The pulley drive structure 11 is mounted on the output end of the stepper motor 601.

[0022] Several cable trays 5 are located inside the gear ring 603. The cable trays 5 are made of stainless steel. During operation, the stepper motor 601 drives the first-stage gear 605, the second-stage gear 604, and the central shaft 602 to rotate in sequence. In turn, the second-stage gear 604 drives the gear ring 603 and the turntable 4 to rotate. At this time, the gear drive unit 6 is used to drive the turntable 4 to rotate quickly. The cooperation of each gear can achieve a large reduction ratio and provide a large torque. The stepper motor 601 provides more precise motion control.

[0023] The stranding and winding mechanism 3 includes a frame 2 fixed on one side of the outer wall of the right-angle frame 1, bearing seats 301 fixed on both sides of the top of the frame 2, a driven shaft 302 rotatably mounted between the two bearing seats 301, and a drum 303 fixed on the outer circumference of the driven shaft 302. The worm gear transmission structure 10 includes a worm fixed to one end of the horizontal shaft 9 and a worm wheel fixed to one end of the surface of the driven shaft 302. The worm and the worm wheel mesh with each other. When the stepper motor 601 shaft rotates, it drives the horizontal shaft 9 to rotate through the pulley transmission structure 11. Then, the horizontal shaft 9 drives the driven shaft 302 and the drum 303 to rotate through the worm gear transmission structure 10. The drum 303 winds and winds the stranded wire. The pulley transmission structure 11 and the horizontal shaft 9 can achieve precise speed matching, so that the wire will not have excessive or insufficient tension due to speed mismatch during stranding, ensuring that the stranding of each wire is uniform and tight.

[0024] In this embodiment, the operator first passes the wires to be twisted through each of the wire guide spools 5. The wires are then manually twisted, and the twisted wires are wound onto the winding mechanism 3, thus completing the preparation of the device. The operator then activates the gear drive unit 6, which drives the turntable 4 to rotate. The wires are drawn from the external feed rack and guided by the wire guide spools 5 to another winding mechanism 3. Because multiple wire guide spools 5 revolve around the turntable 4, the wires are twisted together. During this process... The rotation speed of the reel 4 needs to be coordinated by the gear drive unit 6 to ensure that the wire can be wound in the predetermined twisting pattern. While the wire is twisting, the rotational power of the gear drive unit 6 is transmitted to the wire winding mechanism 3 through the pulley transmission structure 11 and the worm gear transmission structure 10. The wire winding mechanism 3 then ensures that the twisted cable can be evenly wound on the reel. When the cable is completely wound, the system will automatically stop the operation of the winding mechanism, completing the entire twisting and winding process. The operator can inspect and mark the wound cable as needed for subsequent storage and transportation.
