Description

Technical Field

[0001] This invention relates to the field of power cable technology, specifically to a power cable core stranding device. Background Technology

[0002] In the production of power cables, stranding and separating the core wires is one of the core processes. The efficient and safe replacement of the wire reels directly determines the production efficiency and product quality. Currently, most mainstream stranding and separating equipment relies on manual or semi-automated mechanisms for material replacement, which has many technical pain points. Traditional equipment often has a fixed loading platform that lacks a precise guiding and positioning structure. Alignment with the main body of the stranding machine is time-consuming, and the stability after installation is insufficient. Vibration can easily cause the material replacement to shift. Manual assistance is required to clamp the wire reel during material replacement, resulting in low efficiency.

[0003] Furthermore, the rotation of the stranding machine and the loading and unloading actions during material change in traditional equipment are cumbersome and discontinuous, requiring repeated switching of the loading and unloading processes, resulting in long material change cycles and low efficiency. At the same time, the transfer of the wire reel relies on manual pushing, without a dedicated guiding and limiting structure. During the transfer process, the wire reel is prone to rolling and deviating, which leads to gradual damage to the outer surface of the wire reel. Since the wire reel needs to be used repeatedly, the gradual increase in damage will affect the subsequent positioning requirements, further reducing the efficiency of operation and making it difficult to meet the high-efficiency material change requirements of large-scale production.

[0004] Therefore, this solution proposes a power cable core stranding device. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a power cable core stranding wire separating device, which solves the problems of low efficiency in changing the wire reel in existing stranding machines and lack of protection during the wire reel changing process.

The interior of the vertical plates is provided with a second squeezing block at an inclined angle for blocking the displacement of the connecting block. One end of the second squeezing block is provided with a liquid storage cavity for storing liquid, and the other end of the second squeezing block has an arc surface.

[0007] Furthermore, the switching assembly includes a bracket, the top of which is fixedly connected to the bottom of the second support plate. A plurality of first electric push rods are fixedly installed at equal intervals on the top of the bracket. The telescopic ends of the first electric push rods are fixedly connected to the bottom end of the second rectangular frame. A limit rod symmetrically and movably passes through the middle of the top of the second rectangular frame. The top end of the limit rod is fixedly connected to the receiving block. A compression spring is sleeved on the outer peripheral surface of the limit rod, with its two ends respectively abutting against the second rectangular frame and the receiving block.

[0008] Furthermore, both sides of the receiving block are arc-shaped, and the arc-shaped end of the second extrusion block is provided with horizontal grooves at equal intervals. Anti-slip blocks are provided in the multiple horizontal grooves. The anti-slip blocks and the receiving blocks are both made of rubber material.

[0009] Furthermore, the top of the second support plate is provided with multiple rectangular slots at equal intervals, the bottom of each of the multiple rectangular slots is provided with a rectangular hole that can be movably inserted into the second rectangular frame, and both ends of each of the multiple rectangular slots are provided with arc-shaped slots that are adapted to the outer surface of the coil.

[0010] Furthermore, a plurality of fixing blocks are fixedly installed on the top of the second support plate and fixedly connected to the mounting end of the first hydraulic telescopic cylinder. The plurality of clamping plates are located on both sides of the top of the rectangular groove, and the lower surfaces of the plurality of clamping plates are slidably connected to the upper surface of the second support plate.

[0011] Furthermore, both ends of the plurality of clamping plates are provided with arc-shaped clamping grooves corresponding to the curvature of the outer surface of the coil.

[0012] Furthermore, the loading platform has symmetrical first rectangular frames on both sides, and a second hydraulic telescopic cylinder is fixedly installed inside each of the first rectangular frames. The telescopic ends of the second hydraulic telescopic cylinders are fixedly connected to a first extrusion block that is slidably connected to the first rectangular frame. One side of the first extrusion block is inclined, and a first support plate that movably penetrates the loading platform is slidably connected to one side of the first extrusion block. A drive motor that is fixedly connected to the end of the second support plate is fixedly installed in the middle of the top of the first support plate.

[0013] Furthermore, the top of the loading platform is provided with an inclined groove, and the top of the loading platform is provided with positioning holes symmetrically on both sides of the inclined groove. The bottom of the loading platform is provided with limit components below the multiple positioning holes.

[0014] Furthermore, the limiting component includes a support block fixedly connected to the loading platform, a second electric push rod fixedly installed at the top center of the support block, and a lifting plate that is movably inserted into the positioning hole is fixedly connected to the telescopic end of the second electric push rod.

[0015] Furthermore, the lifting plate is provided with a threaded rod inside, and a micro motor is fixedly connected to one end of the lifting plate and fixedly connected to the end of the threaded rod. The threaded rod is threadedly connected to a limiting block that is slidably connected to the upper surface of the lifting plate, and the top of the limiting block is arc-shaped.

[0016] The beneficial effects of the technical solutions provided by the embodiments of the present invention include at least the following: 1. During the descent phase of the receiving coil, the arc-shaped groove of the clamping plate contacts the outer surface of the coil, providing stable clamping and anti-slip function through the arc contour. The precise positioning of the vertical plate ensures a tight fit between the second extrusion block and the receiving block, forming an effective blockage. This prevents the coil from shifting when the receiving block is impacted during coil receiving, ensuring coil positioning accuracy. The high-viscosity buffer solution filled in the internal liquid storage chamber can slowly release pressure through flow when subjected to pressure from the receiving block, improving buffering performance and mitigating the impact vibration caused by the coil's descent. The high-elasticity rubber anti-slip block embedded in the horizontal groove at the arc end significantly enhances the friction with the receiving block, further strengthening the blocking and positioning effect. Simultaneously, the rotation of the second support plate quickly completes the switching between the unloading and loading stations. The entire process can achieve automated continuous operation without manual intervention, enabling multiple coils to be unloaded from the main body of the stranding machine to the second support plate, then transferred to the inclined chute and clamped, transferred, and installed as coils to be loaded. This significantly shortens the material change time for a single coil and improves material change efficiency.

[0017] 2. The first hydraulic telescopic cylinder in the material changing assembly drives the automated clamping structure of the clamping plate with arc-shaped clamping grooves at the end. Combined with the first electric push rods in the receiving assembly that are controlled synchronously to drive the second rectangular frame to lift and lower, and the buffer receiving mechanism of the receiving block to receive the wire reel, and combined with the drive motor to drive the second support plate to achieve the station switching of rotation, this solves the problems of traditional equipment that require manual assistance to clamp the wire reel during material changing, resulting in high labor intensity, and the cumbersome connection between the rotation of the stranding machine body and the loading and unloading actions during the material changing process, which requires repeated process switching and results in a long material changing cycle.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] As shown in the figure, specific structures and devices are marked in the figure to clearly illustrate the structure of the embodiments of the present invention. However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device and environment. Those skilled in the art can adjust or modify these devices and environments according to specific needs. Detailed Implementation

[0031] The technical solutions of the present invention will now be described with reference to the accompanying drawings. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some well-known technologies. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0032] Please see Figures 1-10 This invention provides a technical solution: the basic support system of the equipment consists of a stranding machine body 1, a base 2, and a loading platform 3. The base 2 is made of high-strength metal material and is fixed to the bottom of the stranding machine body 1 with bolts, providing a solid installation foundation for the entire equipment, effectively offsetting the vibration generated during equipment operation, and ensuring the stability of the stranding machine body 1 during high-speed operation. The loading platform 3 serves as the core operating platform for coil transfer and loading / unloading. The platform surface is treated with anti-slip material, and its overall height is adapted to the needs of manual or mechanical coil transfer, which can significantly reduce the labor intensity during coil handling and provide convenient preconditions for subsequent material change operations.

[0033] Based on this, the equipment is equipped with two modules: material changing component 4 and receiving component 5. Material changing component 4 serves as the actuator for changing the wire reel, enabling the automated transfer of the wire reel between the main body 1 of the stranding machine and the loading platform 3, thereby improving material changing efficiency. Receiving component 5 serves as a safety guarantee mechanism for the unloading process, preventing damage to the wire reel due to collision or impact during unloading through precise receiving and buffering protection, thus comprehensively improving the safety and smoothness of the unloading operation.

[0034] The material changing assembly 4 uses the second support plate 401 as the mounting base. The second support plate 401 is made of a high-rigidity alloy plate. Multiple fixing blocks 405 are fixed to the top by welding. The fixing blocks 405 are firmly connected to the mounting end of the first hydraulic telescopic cylinder 406 through flanges to ensure that the first hydraulic telescopic cylinder 406 remains stable during high-frequency telescopic movements and to prevent loosening due to vibration. The telescopic end of the first hydraulic telescopic cylinder 406 is detachably connected to the clamping plate 407 through a pin, which is convenient for later maintenance and replacement. Multiple clamping plates 407 are precisely arranged on both sides of the top of the rectangular groove 402, and their lower surfaces slide in contact with the upper surface of the second support plate 401, which can ensure that the clamping plates 407 move smoothly in a straight line under hydraulic drive and avoid clamping deviation.

[0035] The multiple rectangular slots 402 equidistantly opened at the top of the second support plate 401 provide a standardized placement station for the wire reel. The size of each rectangular slot 402 is customized according to the specifications of commonly used wire reels. The arc-shaped slots 404 opened at both ends of the slot are perfectly matched with the curvature of the outer surface of the wire reel. When the wire reel is placed in the rectangular slot 402, the arc-shaped slots 404 can limit it from both sides, effectively preventing the wire reel from rolling and achieving precise positioning. The rectangular holes 403 opened at the bottom of the rectangular slots 402 not only provide an active channel for the second rectangular frame 503 of the switching component 5, but also provide precise guidance for the lifting and lowering of the second rectangular frame 503, avoiding jamming or deviation during the lifting and lowering process.

[0036] Both ends of the clamping plate 407 are machined with arc-shaped clamping grooves 408. The curvature of these grooves strictly matches the curvature of the outer surface of the wire spool. When the clamping plate 407 moves closer to the wire spool, the arc-shaped clamping grooves 408 can fully fit with the surface of the wire spool, greatly increasing the contact area and distributing the clamping force evenly on the contact surface. This not only improves the clamping firmness but also effectively prevents excessive local pressure from causing deformation or damage to the surface of the wire spool. It should be noted that the first hydraulic telescopic cylinder 406 is powered by an external hydraulic system. This system is equipped with pressure regulating valves, solenoid directional valves, and other supporting control devices, which can realize precise adjustment of clamping force and automated control of clamping action. The relevant technologies are all mature technologies in the industry and will not be described in detail here.

[0037] The switching component 5 is rigidly connected to the bottom of the second support plate 401 via the bracket 501. The bracket 501 can evenly transfer the weight of the switching component 5 to the second support plate 401, ensuring the overall installation stability. Multiple first electric push rods 502 are equidistantly installed on the top of the bracket 501. These first electric push rods 502 adopt a synchronous control method and drive the second rectangular frame 503 to lift and lower through telescopic movement, thereby adjusting the receiving height of the connecting block 510. This can accurately adapt to the unloading requirements of different specifications of wire reels. It should be noted that the first electric push rods 502 use an external power supply and are connected to a matching control device. The relevant technologies are all mature technologies in the industry and will not be described in detail here.

[0038] The limiting rod 504, symmetrically penetrating the top center of the second rectangular frame 503, is fixedly connected to the bottom of the receiving block 510. The limiting rod 504 is chrome-plated, with an extremely smooth surface, ensuring that the receiving block 510 rises and falls smoothly in a straight line. The compression spring 505, sleeved on the outer periphery of the limiting rod 504, is in a pre-compressed state. When the coil falls onto the receiving block 510, the compression spring 505 absorbs the impact energy through further deformation, converting the falling impact force of the coil into the elastic potential energy of the spring, thereby effectively mitigating the impact on the coil and... In the event of equipment damage, the receiving block 510, as the core component for receiving the wire spool, has an arc-shaped groove machined in the middle of its top that perfectly matches the curvature of the middle surface of the wire spool, enabling precise positioning and receiving of the wire spool. The two ends of the receiving block 510 are symmetrically machined with beveled surfaces, which adopt a smooth transition design to guide the wire spool to slide smoothly into the arc-shaped groove during the feeding process, avoiding jamming. Both sides of the receiving block 510 are designed with arc surfaces, which can form a smooth fit with the arc-shaped end of the second extrusion block 507, avoiding jamming during relative sliding.

[0039] The second rectangular frame 503 has symmetrically fixed vertical plates 506 on both sides of its top. The vertical plates 506 have inclined rectangular holes inside, which provide an inclined mounting base for the second extrusion block 507. The mounting angle of the second extrusion block 507 ensures that its curved end fits tightly against the side of the receiving block 510, thereby effectively blocking the receiving block 510 and preventing displacement of the receiving block 510 and the receiving block itself during the wire reel receiving process, which would affect the positioning accuracy. One end of the second extrusion block 507 has a liquid storage cavity 508 filled with a high-viscosity buffer solution. When the second extrusion block 507 is subjected to pressure from the receiving block 510, the buffer solution can release the pressure slowly through flow, further improving the buffering performance of the second extrusion block 507. The other end of the second extrusion block 507 is machined into a curved surface, and the curved end has horizontal grooves at equal intervals. The anti-slip blocks 509 embedded in the horizontal grooves are made of high-elasticity rubber material, which can greatly enhance the friction between the second extrusion block 507 and the receiving block 510, further improving the blocking and positioning effect. Meanwhile, the receiving block 510 is also made of rubber material. This material not only has good elasticity, which can further buffer the impact of the coil, but its anti-slip performance can also improve the stability of the coil after receiving it, effectively protecting the coil from damage.

[0040] The first rectangular frames 301 symmetrically opened on both sides of the loading platform 3 provide installation space for the second hydraulic telescopic cylinder 302. The second hydraulic telescopic cylinder 302 drives the first extrusion block 303 to slide stably. One side of the first extrusion block 303 is processed into a bevel, which forms a precise fit with the bevel at the end of the first support plate 306. When the telescopic component drives the first extrusion block 303 to slide, the horizontal telescopic force can be converted into the vertical lifting force of the first support plate 306 through the force transmission of the bevel, thereby realizing the height adjustment of the first support plate 306. The first support plate 306 is made of high-strength alloy plate, and a limit protrusion is set at the penetration point between it and the loading platform 3 to ensure the smooth lifting action of the first support plate 306. A drive motor 307 is fixed to the top center of one of the first support plates 306 by bolts. The output shaft of the drive motor 307 is fixedly connected to the end of the second support plate 401 by a coupling, which can provide stable power for the rotation of the second support plate 401 and ensure the angle adjustment needs of the second support plate 401 during material change.

[0041] It should be noted that the second hydraulic telescopic cylinder 302 is powered by an external hydraulic system. This system is equipped with supporting control equipment such as pressure regulating valves and solenoid directional valves, which can realize precise adjustment of clamping force and automated control of clamping action. The relevant technologies are all mature technologies in the industry, and will not be described in detail here.

[0042] It should be noted that the drive motor 307 is powered by an external AC power supply and is equipped with a frequency converter and other supporting control equipment, which can achieve precise speed adjustment. The relevant technologies are all mature technologies in the industry, and will not be described in detail here.

[0043] The inclined groove 304 on the top of the loading platform 3 is designed with an angle and the inclined surface is polished, which can significantly reduce the friction when the wire reel slides, making it easier for the wire reel to be quickly transferred on the loading platform 3 and reducing the intensity of manual handling. The positioning holes 305 symmetrically opened on both sides of the inclined groove 304 provide precise insertion guides for the lifting plate 603 of the limiting component 6, ensuring that the limiting component 6 can accurately align with the wire reel for limiting. The limiting component 6 is fixedly connected to the bottom of the loading platform 3 through the support block 601. The support block 601 is made of thickened steel plate, which can provide a stable installation base for the second electric push rod 602. At the same time, guide rods are set on both sides. The second electric push rod 602 drives the lifting plate 603 to rise and fall along the positioning hole 305 through telescopic movement. The limiting height of the limiting block 606 can be adjusted according to the height of the wire reel to adapt to the limiting requirements of the wire reel.

[0044] A threaded rod 604 is mounted inside the lifting plate 603 via bearings. One end of the threaded rod 604 is fixedly connected to the output shaft of the micro motor 605. When the micro motor 605 drives the threaded rod 604 to rotate, the limiting block 606, which is threadedly connected to the threaded rod 604, slides along the upper surface of the lifting plate 603, thereby achieving precise adjustment of the limiting position. The top of the limiting block 606 is machined into an arc surface, which matches the curvature of the outer surface of the coil, thus achieving limiting fixation while avoiding scratches or squeezing damage to the surface of the coil. It should be noted that the micro motor 605 is powered by an external DC power supply and is equipped with supporting equipment such as a forward and reverse controller, which can realize bidirectional sliding adjustment of the limiting block 606. The relevant technologies are all mature technologies in the industry and will not be described in detail here.

[0045] Before the equipment can be put into operation, it needs to be pre-installed and aligned. First, the loading platform 3 is slowly pushed to the designated position along the pre-dug track groove at the bottom of the base 2. The initial alignment of the loading platform 3 and the base 2 is achieved by the guiding action of the track groove. Then, the loading platform 3 is fixed with the help of positioning pins and other auxiliary components to ensure that the loading platform 3, the main body 1 of the stranding machine, and the base 2 form a stable overall structure, laying a precise positional foundation for subsequent loading and unloading operations.

[0046] The operator stops the main body 1 of the stranding machine and simultaneously starts the rotation mechanism of the main body 1, causing the work area where the wire reel is installed to slowly rotate until it is directly above the material changing component 4 at the top of the loading platform 3. After the alignment is completed, the rotation angle of the main body 1 of the stranding machine is locked. Then the material changing component 5 starts first, and multiple first electric push rods 502 on the bracket 501 extend and retract synchronously, driving the second rectangular frame 503 to rise along the rectangular hole 403 at the bottom of the second support plate 401 until the top of the receiving block 510 is flush with the bottom of the wire reel on the main body 1 of the stranding machine. The limit rod 504 ensures that the receiving block 510 rises and falls smoothly, and the pre-compressed compression spring 505 enters the buffering state. At the same time, the second hydraulic telescopic cylinders 302 at both ends of the loading platform 3 drive the first extrusion block 303 to slide, and through the inclined plane cooperation, drive the first support plate 306 and the second support plate 401 to rise.

[0047] It should be noted that the connector block 510 can be directly pushed to the lower surface of the coil. However, after the device is raised, the second support plate 401 cannot rotate due to the size of the base 2. Therefore, the connector block 510 will remain vertically below the coil and maintain a fixed distance from the coil. The distance is based on the length of the range of rotation of the second support plate 401 without affecting it.

[0048] Subsequently, the coil fixing mechanism of the main body 1 of the stranding machine unlocks, and the coil falls vertically under the force of gravity. At the same time, the coil slides into the top arc-shaped groove along the smooth inclined surfaces at both ends of the receiving block 510. The compression spring 505 deforms to absorb the impact force of the fall. The second squeezing block 507 in the vertical plate 506 achieves double positioning protection through the buffer fluid in the liquid storage chamber 508 and the rubber anti-slip block 509. Then, the first hydraulic telescopic cylinder 406 fixed by the fixing block 405 drives the clamping plate 407 to slide along the surface of the second support plate 401. The arc-shaped clamping grooves 408 at both ends of the clamping plate 407 precisely fit the outer surface of the coil. After adjusting to a suitable clamping force through the external hydraulic system, the coil is firmly clamped. After a set of coils is received, the first electric push rod 502 retracts, driving the coil down into the rectangular groove 402 of the second support plate 401. The arc groove 404 limits the coil. The second support plate 401 rotates 180 degrees under the action of the drive motor 307. Figure 3 As shown, the second hydraulic telescopic cylinders 302 at both ends of the feeding platform 3 drive the first extrusion block 303 to slide, and through the inclined surface cooperation, drive the first support plate 306 and the second support plate 401 to descend, so that the wire spool stays on the inclined groove 304 on the upper surface of the feeding platform 3. At this time, after the clamping plate 407 is unlocked, the wire spool rolls on the inclined groove 304 under the action of gravity, and cooperates with the limiting component 6 to complete the automatic feeding of the empty wire spool. Then, the above steps are repeated to complete the feeding of multiple sets of wire spools on the main body 1 of the stranding machine.

[0049] The operator pushes the feed spools into the polishing grooves 304 of the feeding table 3 one by one (e.g., Figure 1 As shown), the limiting component 6 is activated, the second electric push rod 602 drives the lifting plate 603 to rise along the positioning hole 305, the micro motor 605 drives the threaded rod 604 to rotate so that the limiting block 606 limits and fixes the wire reel. Then the clamping plate 407 of the material changing component 4 clamps the wire reel to be fed again. The telescopic components at both ends of the feeding table 3 drive the first extrusion block 303 to move horizontally (at the same time, a guide rod can be added to increase the movement stability of the first extrusion block 303). Through the inclined plane cooperation, the first support plate 306 and the drive motor 307 are driven to rise and fall. The drive motor 307 drives the second support plate 401 to adjust the angle to be parallel to the wire reel installation position of the stranding machine body 1. At this time, the stranding machine body 1 rotates to the feeding position and aligns with the material changing component 4. The clamping plate 407 drives the wire reel to rise and send it into the installation position. After the stranding machine body 1 locks the wire reel, the clamping plate 407 unlocks and resets. This process is repeated to complete the feeding of multiple sets of wire reels. After the feeding is completed, each component returns to the initial state and waits for the next operation cycle.
