Description

Technical Field

[0001] This invention relates to the field of stranding machine technology, specifically to a stranding machine and a stranding and unwinding method. Background Technology

[0002] Stranding is a crucial step in cable manufacturing, involving the orderly twisting of multiple metal conductors to form a stranded core with excellent electrical performance and stable structure. As the requirements for performance, precision, and consistency in wire and cable products continue to increase, stranding machines and their associated unwinding processes face greater technical challenges. Improving processing efficiency while ensuring product quality is a key direction for the industry's development.

[0003] Existing stranding machines typically employ a single mechanical stranding structure. In the pay-off unit, guide rollers and guiding devices pre-treat and guide the wire, which is then twisted in one pass by the main stranding mechanism. Some machines are equipped with tension controllers or length measuring modules to achieve a certain degree of tension and length control. Their working principle mainly relies on a single gear transmission or belt drive system to rotate the winch, achieving the winding and combination of conductors. The operating structure is relatively fixed.

[0004] However, existing technologies generally suffer from the following problems: the stranding process can only perform one stranding operation, which cannot meet the requirements of some high-performance cables that require multiple stranding operations to improve flexibility and anti-interference capabilities. If secondary or multiple stranding operations are required, multiple machines or processes are needed, which not only increases equipment investment and production cycle but also reduces overall production efficiency. Therefore, there is an urgent need for a stranding equipment that can integrate multiple stranding functions to simplify the process, improve production efficiency, and enhance stranded wire performance. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a stranding machine and a stranding and unwinding method, solving the problem that the stranding machine can only strand once, and multiple stranding operations are required to achieve better results.

A limiting assembly is provided between the limiting rod 1 and the guide rod. A measuring assembly is provided on one side of the stranding machine body.

[0010] Preferably, a crossbar is fixedly connected inside the material rack, a mounting rod is fixedly connected to one side of the crossbar, and a material roller is rotatably connected to the outer wall of the mounting rod.

[0011] Preferably, a support rod is fixedly connected to the top of the material rack, a fixed shaft is fixedly connected inside the support rod, and a gear is rotatably connected to the outer wall of the fixed shaft.

[0012] Preferably, the support rod is fixedly connected to symmetrically arranged limiting posts, the outer wall of the limiting posts is provided with a rack, the rack is provided with a limiting groove, and the rack is slidably connected to the outer wall of the limiting posts through the limiting groove.

[0013] Preferably, one end of the rack is rotatably connected to a guide wheel four, the other end of the rack is rotatably connected to a guide wheel five, a fixed shaft two is fixedly connected to one side of the rack, and a connecting block two is rotatably connected to the outer wall of the fixed shaft two.

[0014] Preferably, a connecting block is rotatably connected to the outer wall of the fixed shaft, a telescopic rod is fixedly connected to one side of the connecting block, one end of the telescopic rod is fixedly connected to one side of the connecting block, a tension spring is sleeved on the outer wall of the telescopic rod, one end of the tension spring is fixedly connected to one side of the connecting block, and the other end of the tension spring is fixedly connected to one side of the connecting block.

[0015] A method for releasing stranded wire includes the following steps: S1: The material roller is mounted on the material rack via the mounting rod, and then the copper core passes through guide wheel four and guide wheel five in sequence; S2: During the movement, the copper core pulls the rack, which in turn causes the rack to move synchronously on both sides through the gear. At the same time, the rack and gear are supported by the tension of the tension spring, so that the rack can always be taut against the copper core. S3: The copper core passes through guide wheel three and around guide wheel one for the first twisting, forming three groups of fine wires, each group with 20 wires, and each group is twisted into one strand. Then the copper core passes through guide wheel two and is wrapped around the outer wall of the measuring wheel. S4: The position of the limiting plate is adjusted by sliding the sliding sleeves on both sides on the outer wall of the sliding sleeve, and the sliding sleeve is fixed to the outer wall of the limiting rod by hand-tightening the bolt. S5: When it is necessary to adjust the position of the perforated plate, the perforated plate slides on the outer wall of the limiting rod through the second sliding sleeve, the perforated plate is fixed by the second hand-tightened bolt, and the second guide wheel is adjusted on the outer wall of the limiting rod through the third sliding sleeve. S6: Then, before entering the perforated plate, a second twisting is performed, and the two strands are twisted together into one.

[0016] Working principle: When using this stranding machine, the material roller is first installed on the material rack via the mounting rod. Then, the copper core passes through guide wheel four and guide wheel five in sequence. Guide wheel four and guide wheel five are fixed on the rack. At the same time, the rack is axially symmetrical about the gear, so that the copper core pulls the rack during the movement. In turn, the rack drives the racks on both sides to move synchronously through the gear. At the same time, the rack and the gear are supported by the tension of the tension spring, so that the rack can always keep the copper core taut. The limiting post is connected to the connecting block one and the connecting block two and the fixed shaft one and the fixed shaft two through the connecting block one. The rack passes through the limiting post and is limited in the limiting groove, achieving the effect of adaptive adjustment of copper wire tension. The copper core then passes through guide wheel three, around guide wheel one, then through guide wheel two, and wraps around the outer wall of the measuring wheel. Next, the copper core passes through the guide hole in the perforated plate and enters the through hole inside the stranding machine body for the next operation. The limiting rod one and the guide rod are limited by a limiting plate. The limiting plate's position is adjusted by sliding sleeves one on both sides against the outer wall of sleeve one, and sleeve one is fixed to the outer wall of the limiting rod one by a hand-tightening bolt. When the position of the perforated plate needs adjustment, the perforated plate slides against the outer wall of the limiting rod one via sleeve two. The perforated plate is fixed by hand-tightening bolt two, and guide wheel two is adjusted on the outer wall of limit rod one by sliding sleeve three. During the process of copper core stranding, it drives the measuring wheel to rotate, and then the speed of the measuring wheel is detected by the speed measuring module to accurately calculate the strand length of copper core. When the copper core is on guide wheel one, it is stranded for the first time. There are a total of 3 groups of fine wires, 20 wires in each group, and each group is stranded into one wire. Then, before entering the perforated plate, it is stranded for the second time, and the wires are stranded together into one wire. This achieves the effect of multiple stranding to improve the performance of the wire core.

[0017] In summary, this application includes at least one of the following beneficial technical effects: 1. This invention involves the first stranding of copper cores on the guide wheel, with a total of 3 groups of fine wires, 20 wires in each group, and each group is stranded into one wire. Then, before entering the perforated plate, a second stranding is performed, and the wires are stranded together into one strand. This achieves the effect of multiple stranding to improve the performance of the wire core, solving the problem in the prior art that the stranding machine can only strand once, and multiple stranding is required to achieve better results, thus improving the production efficiency of the stranding machine.

[0018] 2. In this invention, the copper core is wound in an S-shape around the outer wall of the measuring wheel. During the twisting process of the copper core, the measuring wheel is driven to rotate. The speed of the measuring wheel is detected by the speed measuring module, and the length of the copper core strand is accurately calculated. This achieves the effect of facilitating the measurement of strand length, solves the problem of inaccurate measurement in traditional stranding machines, and improves the practicality of stranding machines.

[0019] 3. In this invention, the copper core pulls the rack during movement, which in turn causes the rack to move synchronously on both sides through the gear. At the same time, the rack and gear are supported by the tension of the tension spring, so that the rack can always keep the copper core taut. This achieves the effect of adaptive adjustment of copper wire tension, which solves the problem that traditional tension adjustment requires frequent adjustment and motor control, and improves the convenience of the stranding machine.

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.

[0023] Example: Please see the appendix Figure 1 -Appendix Figure 4This invention provides a stranding machine, including a stranding machine body 1, a guide frame 2, and a material rack 3. A bracket 4 is fixedly connected to the top of the stranding machine body 1 to support the upper guide structure and ensure the smooth operation of the conductor. A guide wheel 5 is rotatably connected to one side of the bracket 4 to guide the copper core 21 in its running direction before the initial stranding, ensuring that the conductors are neatly arranged. A guide rod 6 is fixedly connected inside the stranding machine body 1 to provide positioning support for the stranding assembly and guide the copper core 21 to run along a specified path. A through hole 8 is opened inside the guide rod 6, through which the copper core 21 can pass, so that the copper core 21 maintains a consistent guiding direction during the guiding process and prevents misalignment.

[0024] A stranding assembly is provided on one side of the stranding machine body 1 to realize the stranding operation of multi-core wires and improve the stranding quality and efficiency. The stranding assembly includes a limiting rod 7, one end of which is fixedly connected to one side of the stranding machine body 1 and serves as a guide rail for installing the sliding sleeve and stranding elements, ensuring the smooth movement of the stranding components. A sliding sleeve 15 is slidably connected to the outer wall of the limiting rod 7. The sliding sleeve 15 can be adjusted axially along the limiting rod 7 to facilitate the adjustment of the position of the perforated plate 16 to accommodate wire bundles of different sizes. A perforated plate 16 is fixedly connected to one side of the sliding sleeve 15 for arranging and guiding the wires before the second stranding, improving the uniformity of the wire bundle. A guide hole 17 is opened inside the perforated plate 16 to further guide the multi-strand copper cores 21 and improve the accuracy of the multi-core wire arrangement.

[0025] The outer wall of the sliding sleeve 15 is threaded with a hand-tightening bolt 18, which is used to fix the sliding sleeve 15 at the designated position of the limiting rod 7, so as to achieve quick positioning and loosening and improve adjustment efficiency. The sliding sleeve 15 is fixed to the outer wall of the limiting rod 7 by the hand-tightening bolt 18, thereby ensuring that the perforated plate 16 is stable in position during the stranding process and is not prone to displacement. The outer wall of the limiting rod 7 is slidably connected to the sliding sleeve 19, which is used to install the guide wheel 20 and realize the adjustable guide path. The guide wheel 20 is rotatably connected to one side of the sliding sleeve 19, which is used to guide the running direction of the copper core 21 again, providing path control for composite stranding and avoiding the copper core 21 from crossing and winding. A limit component is set between the limiting rod 7 and the guide rod 6 to achieve precise limit and stable support for the sliding parts.

[0026] A measuring component is installed on one side of the stranding machine body 1 to detect the wire speed and length of the copper core 21 in real time during operation. Copper cores 21 are installed on the outer walls of guide wheel 5, measuring wheel 10, and guide wheel 20. The copper cores 21 pass sequentially through guide wheel 5, measuring wheel 10, and guide wheel 20, achieving continuous operation of two stranding operations and length measurement. The limiting component includes a limiting plate 13, which passes through the outer wall of the guide rod 6 to provide a support reference for the sliding sleeve 12, enhancing the structural stability of the system. 3. Sliding sleeves 12 are fixedly connected to both sides. Sliding sleeves 12 are used to slide with limiting rods 7 to achieve adjustable positioning of limiting plate 13. Sliding sleeves 12 are slidably connected to the outer wall of limiting rods 7 to facilitate adjustment of the installation position of the limiting component on limiting rods 7. Sliding sleeves 12 are internally threaded with hand-tightening bolts 14 for quick manual fixation. Sliding sleeves 12 are fixed to the outer wall of limiting rods 7 by hand-tightening bolts 14, thereby ensuring that the limiting plate 13 is stable during operation and preventing loosening.

[0027] The measuring component includes a second limiting rod 9. One end of the second limiting rod 9 is fixedly connected to one side of the stranding machine body 1 to support the measuring wheel 10 and maintain its axial stability. The other end of the second limiting rod 9 is rotatably connected to the measuring wheel 10. A copper core 21 is wound around the outer wall of the measuring wheel 10. When the copper core 21 moves, it drives the measuring wheel 10 to rotate, thereby realizing mechanical feedback of the wire movement length. The other end of the second limiting rod 9 is fixedly connected to a speed measuring module 11. The speed measuring module 11 works in conjunction with the measuring wheel 10 to acquire the rotational speed data of the measuring wheel 10 in real time and convert it into the running length of the copper core 21, thereby improving the accuracy of length measurement.

[0028] Please see the appendix Figure 5 -Appendix Figure 10 The top of the guide frame 2 is rotatably connected to the guide wheel 3 22, which is used to further guide the direction of the copper core 21 to enter the stranding machine, ensuring the stability of the running path of the copper core 21 before entering the stranding machine and reducing the risk of deviation and entanglement. The copper core 21 is set on the outer wall of the guide wheel 3 22, so that the copper core 21 is guided by the guide wheel 3 22 to roll and improve the smoothness of the wire entry and protect the surface of the copper core from damage.

[0029] A crossbar 23 is fixedly connected inside the material rack 3. The crossbar 23 serves as a structural support element, used to support the installation position of components such as the mounting rod 24, thereby enhancing the overall stability of the material rack 3. A mounting rod 24 is fixedly connected to one side of the crossbar 23. The mounting rod 24 is used to install and support the material roller 25, ensuring accurate positioning of the rotation axis of the material roller 25 during the wire feeding process. The material roller 25 is rotatably connected to the outer wall of the mounting rod 24. The material roller 25 serves as a wire feeding drum and can be passively rotated as it is pulled by the copper core 21, ensuring a continuous and stable supply of copper core 21.

[0030] A support rod 26 is fixedly connected to the top of the material rack 3. The support rod 26 serves as a structural support for the gear and the limiting mechanism, ensuring the stable installation of related components. A fixed shaft 32 is fixedly connected inside the support rod 26. The fixed shaft 32 is the supporting shaft for the gear 27 and provides a fulcrum for rotation. The gear 27 is rotatably connected to the outer wall of the fixed shaft 32. During rotation, the gear 27 meshes with the rack 28 to realize motion transmission and synchronous adjustment functions.

[0031] The support rod 26 is internally fixedly connected with symmetrically arranged limiting posts 38, which are used to guide the rack 28 to slide linearly and ensure the accuracy of the adjustment path. The outer wall of the limiting post 38 is provided with a rack 28, which meshes with the gear 27 to realize automatic tension adjustment during the pulling process of the copper core 21, and at the same time realizes the tensioning function through the telescopic mechanism. The rack 28 has a limiting groove 29 inside, which cooperates with the limiting post 38 to form a sliding guide structure to ensure that the rack 28 slides smoothly along the preset path during operation.

[0032] The rack 28 is slidably connected to the outer wall of the limiting post 38 through the limiting groove 29, which is used to realize the tension adjustment of the controlled stroke and prevent the rack 28 from leaving the running trajectory. One end of the rack 28 is rotatably connected to the guide wheel 4 30, which is used to further guide the copper core 21 on the running path and ensure that the copper core 21 is subjected to uniform force. The other end of the rack 28 is rotatably connected to the guide wheel 5 31, which forms an auxiliary tensioning structure with the guide wheel 4 30 to improve the running stability of the copper core 21.

[0033] A fixed shaft 23 is fixedly connected to one side of the rack 28. The fixed shaft 23 serves as a rotational support for the connecting block 25 and is used to connect the tension adjustment structure. The outer wall of the fixed shaft 23 is rotatably connected to the connecting block 25. The connecting block 25 cooperates with the telescopic rod 36 to achieve flexible adjustment of the rack 28. The outer wall of the fixed shaft 12 is rotatably connected to the connecting block 14. The connecting block 14 and the connecting block 25 form an adjustable linkage component to improve the coordination and response speed of tension adjustment.

[0034] A telescopic rod 36 is fixedly connected to one side of connecting block 34. The telescopic rod 36 drives connecting block 35 through its extension and retraction, which in turn drives rack 28 to achieve adaptive tension, improving the tension balance of copper core 21 during operation. One end of the telescopic rod 36 is fixedly connected to one side of connecting block 35 to ensure the continuity of motion transmission. A tension spring 37 is sleeved on the outer wall of the telescopic rod 36. The tension spring 37 provides basic tension, keeping rack 28 in a constant tension state. One end of the tension spring 37 is fixedly connected to one side of connecting block 35, and the other end is fixedly connected to one side of connecting block 34. The spring tension is used to counteract the tension fluctuation of copper core 21, achieving automatic compensation and improving the sensitivity and stability of the tension adjustment system.

[0035] A method for releasing stranded wire includes the following steps: S1: The material roller 25 is mounted on the material rack 3 via the mounting rod 24, and then the copper core 21 passes through the guide wheel 4 30 and the guide wheel 5 31 in sequence; S2: During the movement, the copper core 21 pulls the rack 28, which in turn causes the rack 28 to move synchronously on both sides through the gear 27. At the same time, the rack 28 and the gear 27 are supported by the tension of the tension spring 37, so that the rack 28 can always be taut on the copper core 21. S3: Copper core 21 passes through guide wheel 3 22 and around guide wheel 1 5 for the first twisting, forming 3 groups of fine wires, 20 wires in each group, and each group is twisted into one wire. Then copper core 21 passes through guide wheel 2 20 and is wrapped around the outer wall of measuring wheel 10. S4: The position of the limiting plate 13 is adjusted by sliding the sliding sleeves 12 on both sides on the outer wall of the sliding sleeves 12, and the sliding sleeves 12 are fixed to the outer wall of the limiting rod 7 by the hand-tightening bolts 14. S5: When it is necessary to adjust the position of the perforated plate 16, the perforated plate 16 slides on the outer wall of the limiting rod 7 through the sliding sleeve 2 15, the perforated plate 16 is fixed by the hand-tightening bolt 2 18, and the guide wheel 20 is adjusted on the outer wall of the limiting rod 7 through the sliding sleeve 3 19. S6: Then, before entering the perforated plate 16, a second twisting is performed, and the two strands are twisted together.

S4: The position of the limiting plate (13) is adjusted by sliding the sliding sleeves (12) on both sides on the outer wall of the sliding sleeves (12), and the sliding sleeves (12) are fixed to the outer wall of the limiting rod (7) by the hand-tightening bolts (14); S5: When it is necessary to adjust the position of the perforated plate (16), the perforated plate (16) slides on the outer wall of the limiting rod (7) through the sliding sleeve (15), the perforated plate (16) is fixed by the hand-tightening bolt (18), and the guide wheel (20) is adjusted on the outer wall of the limiting rod (7) through the sliding sleeve (19). S6: Then, before entering the perforated plate (16), a second twisting is performed to combine them into one strand.
