[0017] 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.
[0018] Specific implementation examples: like Figure 1 As shown, a multi-core cable manufacturing stranding equipment includes a frame 1, a winding mechanism 2 mounted on the frame 1, a planetary gear assembly 3 mounted on the frame 1, a stranding module 4 mounted on the planetary gear assembly 3, a core placement tray 8 mounted on the other side of the planetary gear assembly 3, a fixing frame 6 mounted on the outer periphery of the planetary gear assembly 3, a limiting mechanism 7 mounted at the center of the fixing frame 6, and a core protective layer placement tray 5 mounted on the planetary gear assembly 3. The planetary gear assembly 3 is driven by a motor; In this mechanism, the positional relationship of each component is as follows: the back of the planetary gear assembly 3 is the core placement disc 8, the center of the front is the stranded module 4, the outermost part is the fixing frame 6, the core protective layer placement frame 5 is located between the stranded module 4 and the fixing frame 6, and is distributed in a ring symmetrical distribution to ensure balanced tension during the wrapping process. The wire outlet of the stranded module 4 is located after the wire outlet of the core protective layer placement frame 5. The limiting mechanism 7 is located in front of the wire outlet of the core protective layer placement frame 5. The winding mechanism 2 is located on the axial extension line of the wire outlet of the limiting mechanism 7 to ensure that the cable maintains a straight running trajectory during the traction process and reduces offset resistance. In this mechanism, the wire cores enter the stranding module 4 through the wire core placement tray 8, and are driven by the planetary gear assembly 3 to achieve synchronous rotation, so that multiple wire cores are evenly stranded. The limiting mechanism 7 dynamically corrects the position of the wire cores to prevent eccentricity. The fixing frame 6 enhances the structural stability and reduces vibration. Together with the wire core protective layer placement frame 5, the cable is covered with insulation material, realizing integrated continuous production, effectively improving stranding accuracy and work efficiency. This equipment significantly reduces the floor space, reduces maintenance difficulty, and makes operation more convenient through optimized transmission layout and modular design. The function of winding mechanism 2 is to wind the cable under constant tension after twisting to ensure uniform wire diameter and tight arrangement, and to avoid loose strands or overlap. like Figures 2-3 As shown, the planetary gear assembly 3 includes a main gear 32, with three sets of secondary gears 33 evenly distributed around its outer circumference. Gear rings 31 mesh with the outer sides of the three sets of secondary gears 33. The main gear 32 is driven by a motor. A main shaft 35 is located at the center of the main gear 32, and a rotating disk 81 is fixedly mounted on the main shaft 35. A wire core placement disk 8 is mounted on the rotating disk 81. A wire core protective layer placement frame 5 is mounted on the secondary gears 33. A stranding module 4 is mounted on the main gear 32, and the stranding module 4 rotates synchronously with the main gear 32 to ensure a constant stranding pitch. The gear rings 31 are fixed to the frame 1 and remain stationary, forming a planetary transmission structure. Driven by a motor, the main wheel 32 drives the main shaft 35 to rotate, causing the rotating disk 81 and the wire core placement disk 8 to rotate synchronously. At the same time, the main wheel 32 meshes with the secondary wheel 33, which rolls along the inner side of the toothed ring 31, driving the wire core protective layer placement frame 5 to revolve, thus achieving uniform winding of the coating material. In this structure, the main wheel 32, as the core of the planetary transmission, works with the secondary wheel 33 to achieve a two-stage transmission. The main wheel 32 only rotates on its own axis under the constraint of the fixed toothed ring 31, while the secondary wheel 33 revolves around the center. The rotation direction of the main wheel 32 is opposite to that of the secondary wheel 33, which allows the rotation of the wire core stranding to be opposite to the revolution of the wire core protective layer coating. This realizes the basic principle of cable stranding processing, thereby effectively avoiding the superposition of torsional stress caused by the same-direction rotation between the coating layer and the wire core, improving the coating density and surface flatness, ensuring the synchronization of the wire core stranding, and ensuring the continuity of the protective layer coating. This effectively avoids material stretching or accumulation caused by the difference in rotation speed, improving the overall operational stability and product consistency. The core protective layer placement frame 5 is provided in three sets, and a stabilizing frame 52 is provided between the three sets of core protective layer placement frames 5. The stabilizing frame 52 is triangular star-shaped and is used to support and fix the three sets of core protective layer placement frames 5, so that the positions of the three sets of core protective layer placement frames 5 are constant, and the consistency of the orbital trajectory and the stability of operation are maintained. The stabilizer 52 is installed in front of the wire output end of the stranded wire module 4, and the stabilizer 52 has a wire inlet hole 521 at the center. The inlet hole 521 is used to guide the wire core from the stranding module 4 into the stranding area, ensuring that the wire core remains stably centered before entering the coating process. During the processing, the wire core enters the inlet hole 521 from the outlet end of the stranding module 4 for stranding. Therefore, the stabilizing frame 52 can keep the positional relationship between the three sets of wire core protective layer placement frames 5 constant. Thus, the center hole position of the stabilizing frame 52 coincides with the axis of the spindle 35, ensuring that the wire core is in a precise center position when passing through the inlet hole 521, effectively avoiding the problem of uneven coating thickness caused by eccentricity. At the same time, multiple sets of wire cores can be stranded by entering the inlet hole 521 with a constant position from the outlet end of the stranding module 4. The multiple wire cores are twisted into a tightly arranged cable by rotation, ensuring that each wire core is evenly stressed and tightly twisted. like Figures 3-4 As shown, the main shaft 35 is fixedly connected to the rotating disk 81. Several sets of wire core outlet frames 82 are installed on the rotating disk 81. Wire core outlet cylinders 83 are rotatably installed on the wire core outlet frames 82. A rotating shaft 84 is installed on the main shaft 35. A fixed seat 85 is installed on the outside of the rotating shaft 84. The fixed base 85 is used to stabilize the installation position of the rotating shaft 84 and ensure that it does not deflect radially during high-speed rotation. The fixed connection between the rotating shaft 84 and the main shaft 35 enables the rotating shaft 84 and the main shaft 35 to operate synchronously, ensuring the stability and accuracy of power transmission. The rotating shaft 84 and the main shaft 35 are driven by the same motor to ensure synchronous speed. The wire core outlet cylinder 83 is the main component for installing the wire core. It is rotatably mounted on the wire core outlet frame 82 to ensure smooth wire core outlet. The wire core outlet drum 83 and the wire core outlet frame 82 are evenly distributed around the circumference, which can realize the synchronous feeding of multiple sets of wire cores, ensure that the tension of each wire core is consistent and the arrangement is uniform, and effectively prevent entanglement or loosening caused by differences in feeding speed; the wire core outlet drum 83 maintains axial stability during rotation. A protective disc 34 is installed on the main shaft 35. The function of the protective disc 34 is to prevent external impurities from entering the planetary gear assembly 3, ensuring a clean operating environment for the transmission system, and avoiding wear or jamming of the planetary gears due to dust or debris interference. The top of the main shaft 35 is equipped with a wire outlet plate 41, which rotates synchronously with the main shaft 35; the wire outlet plate 41 is used to guide the untwisted wire cores out. The rotating disk 81 has several sets of first cable outlet holes 811 evenly distributed around its circumference; the main wheel 32 has several sets of second cable outlet holes 321 evenly distributed around its circumference; the protective disk 34 has several sets of third cable outlet holes 341 evenly distributed around its circumference; and the cable outlet disk 41 has several sets of fourth cable outlet holes 411 evenly distributed around its circumference. In this structure, the wire exit holes are arranged sequentially to ensure that the wire core is led out from the wire core exit tube 83, passes through the first wire exit hole 811, the second wire exit hole 321, the third wire exit hole 341, and finally is guided to the stranding module 4 through the fourth wire exit hole 411. The path is clear and the layers are distinct. Each stage of wire exit holes is distributed in concentric circles with the main shaft 35 as the center, ensuring that the multi-strand wire cores maintain a uniform phase angle and constant tension during rotation, avoiding uneven stranding or stress concentration caused by positional deviation. Each wire exit hole is strictly perpendicular to the axis of the main shaft 35, and the central axis is aligned accordingly, ensuring that the wire core does not deflect or twist during high-speed wire feeding, effectively improving the stranding accuracy and the roundness of the finished cable. like Figure 5 As shown, the wire core protective layer placement frame 5 includes a fixed column 53, which is fixedly connected to the secondary wheel 33. A wire outlet tube connecting frame 512 is installed on the fixed column 53, and a protective layer wire outlet tube 511 is installed on the wire outlet tube connecting frame 512. The protective layer cable outlet drum 511 is used to store and release the outer protective material of the cable. The protective layer cable outlet drum 511 can rotate smoothly on the cable outlet drum connecting frame 512 to ensure that the protective layer material is released evenly. A stabilizing frame 52 is provided between the three sets of fixed columns 53. The stabilizing frame 52 is used to enhance the structural rigidity between the fixed columns 53, prevent the support from deforming due to vibration or torque changes, and ensure the stability of the protective layer cable outlet cylinder 511 during rotation. The three sets of fixed columns 53 and the stabilizing frame 52 form a triangular support structure, which further improves the overall load-bearing capacity and anti-eccentric load performance. When the finished cable exits the device, the cable surface may be scratched or deformed due to excessive twisting amplitude. At the same time, excessive twisting amplitude during the winding of the finished cable may also lead to uneven winding tension, affecting the neatness of the winding. Therefore, it is necessary to limit the cable when it exits the device. Limiting the cable can effectively constrain its radial runout and avoid surface damage and tension fluctuations caused by excessive swing. Therefore, as Figure 6 As shown, the fixed frame 6 is provided with a limiting mechanism 7. The limiting mechanism 7 includes a housing 71, a side tooth transmission ring 72 is rotatably disposed on the housing 71, and a fixed connecting frame 73 is installed on the housing 71. One side of the side tooth transmission ring 72 is provided with teeth (not shown in the figure), and a gear 75 is meshed on the side tooth transmission ring 72. A threaded post 74 is threadedly connected to the center of the gear 75. The threaded post 74 is threadedly connected to the fixed connecting frame 73, and a limiting post 76 is provided at the lower end of the threaded post 74. In this mechanism, the rotating side gear transmission ring 72 drives the gear 75 to rotate, thereby driving the threaded column 74 to rise and fall axially, adjusting the distance between the limit column 76 and the center of the cable outlet, and realizing adaptive limiting for cables of different diameters; The gears 75 are arranged in several sets, evenly distributed circumferentially on the outer side of the housing 71. The arrangement of several sets of gears 75 allows the side gear transmission ring 72 to simultaneously control the rotation of multiple gears 75, ensuring synchronous limiting in all directions and improving adjustment accuracy and stability. At the same time, several sets of gears 75 are also threaded with several sets of threaded posts 74, allowing multiple sets of limiting posts 76 to adjust synchronously towards the center, achieving uniform clamping and dynamic adaptive limiting of the cable, effectively suppressing radial offset and vibration during the cable exit process, and ensuring the surface quality and winding neatness of the cable. The multi-point synchronous adjustment mechanism further enhances the adaptability of the limiting mechanism 7 to cables of different specifications, maintaining stable tension output during continuous operation and meeting the requirements of high-precision cable processing. The top of the limiting post 76 is equipped with a rolling ball (not shown in the figure). The rolling ball contacts the surface of the cable and forms rolling friction, which effectively reduces the risk of scratching the outer layer of the cable during the limiting process, protects the integrity of the cable insulation layer or shielding layer, and makes the cable pass through the limiting mechanism 7 more smoothly, reducing running resistance and local wear, and further improving the stability of the cable exit and the surface finish. The setting of the rolling ball also helps to adapt to the slight sway of the cable in real time, maintain constant contact pressure, avoid indentation or deformation caused by rigid contact, and ensure continuous and reliable processing. Two sets of the side gear transmission rings 72 are arranged opposite each other, located on both sides of the housing 71. The two sets of side gear transmission rings 72 rotate synchronously to ensure balanced torque transmission and avoid structural load imbalance and motion jamming caused by unilateral force. After adjusting the limiting distance for the cable, the limiting mechanism 7 can fix the threaded post 74 by tightening the lock nut to prevent loosening and retraction caused by vibration during processing. After the finished cable is processed, it needs to be wound. Therefore, a stable winding device is needed to achieve neat and compact winding. like Figure 7 As shown, the winding mechanism 2 includes a base 25, which is fixedly connected to the frame 1. A limiting cylinder 21 is provided on the base 25, and a finished winding drum 24 is provided on the base 25. The finished winding drum 24 is driven by a motor. A reciprocating mechanism 23 is provided between the limiting cylinder 21 and the finished winding drum 24, and a movable cylinder 22 is installed on the reciprocating mechanism 23. In this mechanism, the main driving force is the motor driving the finished cable reel 24 to rotate, causing the cable to wind around the surface of the finished cable reel 24. During this process, the limiting cylinder 21 is used to guide the cable into the winding area, ensuring the accuracy of the initial winding position and providing a limiting tension for the cable winding, so that the cable maintains stable tension in the early stage of winding, avoiding loosening or mis-layering. The reciprocating mechanism 23 can drive the moving cylinder 22 to reciprocate. The reciprocating mechanism 23 is a reciprocating screw structure, driven by a servo motor, which is an existing mature technology. Its specific principle will not be elaborated here. The reciprocating mechanism 23 precisely controls the moving cylinder 22 to move left and right along the axis, so that the cable is evenly distributed on the surface of the finished cable reel 24, realizing layered winding arrangement, avoiding cable accumulation or overlap, and ensuring tight and neat winding. The inner diameter of the moving cylinder 22 is slightly larger than the outer diameter of the cable, which not only ensures the smooth passage of the cable, but also limits its swing amplitude, further improving the cable laying accuracy. In summary, this multi-core cable manufacturing stranding equipment, through the synergistic action of the limiting mechanism 7 and the winding mechanism 2, achieves dynamic tension control and precise wire arrangement during the stranding and winding process of the cable, effectively improving the forming quality and production efficiency of the multi-core cable, while reducing the risk of mechanical damage to the cable body. It is suitable for high-strength, continuous, large-scale cable production operations. Furthermore, the stranding of the core and the stranding of the core protective layer can be carried out simultaneously, sharing the same motor drive. The power is distributed to two transmission chains through the planetary gear assembly 3, achieving synchronous and coordinated control of core stranding and insulation layer coating. This effectively improves production efficiency, reduces floor space, lowers equipment investment costs, and optimizes the transmission chain layout. The limiting mechanism 7 can flexibly adjust the limiting distance according to the needs of different cable specifications, adapting to the processing requirements of various wire diameters and enhancing the equipment's versatility.
