Description

Technical Field

[0001] The present invention belongs to the technical field of cable production equipment, and more specifically, particularly relates to a cable core stranding device for cable production. Background Art

[0002] During the cable manufacturing process, core stranding is one of the key technological processes. Its purpose is to strand multiple single-strand conductors (such as copper wires) into an integral whole according to specific rules to improve the flexibility, tensile strength, and electrical performance of the cable. Traditional core stranding devices usually adopt three basic steps: wire pay-off, stranding, and wire take-up.

[0003] The current cable core stranding device for cable production still has some deficiencies during actual use: 1. After the stranding of multiple copper wires by the traditional cable core stranding device for cable production, there is a lack of a rounding mechanism, resulting in an irregular cross-sectional shape of the cable (such as oval or flattened), which in turn affects the covering effect of the subsequent insulating layer or sheath, and even reduces the voltage withstand performance of the cable; 2. In the conveying link of the traditional cable core stranding device for cable production, generally only a single power is relied on for winding, lacking additional auxiliary conveying power, resulting in large fluctuations in the tension of the cable during conveying, and especially prone to wire breakage or surface scratches during high-speed wire take-up.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a cable core stranding device integrating efficient stranding, dynamic rounding, and adaptive traction is provided to improve the quality of core stranding.

[0008] Further, two round rods one are fixedly installed on each U-shaped plate. Each round rod one movably penetrates through the rotating ring. An arc-shaped plate is fixedly connected to every two round rods one. Each arc-shaped plate is attached to the outer end of the rotating ring.

[0012] Furthermore, a hexagonal rod is fixedly installed at the shaft end at the bottom of the frame on one side, and the hexagonal rod is slidably installed in the hexagonal groove.

[0014] Furthermore, the second bevel gear meshes with the first bevel gear, and a toothed synchronous belt is sleeved on the first synchronous pulley and the second synchronous pulley.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. For the cable core stranding device used in cable production, for the stranded cable core, the device realizes the roundness adjustment function through two sets of U-shaped plates and pressure wheels distributed in the swivel ring. The two pressure wheels in each set of U-shaped plates are distributed in the horizontal and vertical directions respectively. The concave arc groove 1 on their surfaces is adapted to the outer contour of the cable core, which can comprehensively wrap and accurately press the cable from multiple directions. At the same time, the U-shaped plate is connected to the inner wall of the swivel ring through spring 1, endowing the pressure wheel with a certain floating adjustment ability. The horizontally and vertically distributed pressure wheels are self-adaptively pressed against the cable through spring 1, continuously correcting the roundness of the cable core during rotation, ensuring that the cross-sectional shape is regular (reducing oval or flat deformation). The U-shaped plate is connected to the swivel ring through spring 1, and the pressure wheel can finely adjust the pressure with the fluctuation of the cable diameter, not only ensuring the roundness adjustment effect but also avoiding cable core deformation or insulation layer damage caused by excessive extrusion, ensuring the integrity and quality of the cable.

[0016] 2. For the cable core stranding device used in cable production, in the driving link of the take-up reel, the power of motor 1 is transmitted through a series of transmission components, causing the rotation of shaft 2, and then driving gear 3 meshing with the toothed ring, driving the swivel ring to rotate around its axis. When the swivel ring rotates, it drives the U-shaped plate and the pressure wheel to rotate around the cable core together. The roundness adjustment method of continuously applying pressure to the cable core during the dynamic rotation process can act on the cable core more comprehensively and evenly compared with the static roundness adjustment, further ensuring the effectiveness of the roundness adjustment operation, enabling the cable core to better maintain a stable circular structure during subsequent use, and improving the performance and reliability of the cable.

[0017] 3. For the cable core stranding device used in cable production, the round cable core passes through two traction wheels in the frame. Through a series of gear transmissions such as shaft 2, bevel gears, shaft 3, gear 5, and gear 6, the power is transmitted to the traction wheels. The two traction wheels are connected by meshing gear 2 to ensure synchronous rotation, and the rotation direction is the same as the cable winding and conveying direction, actively "pushing" the cable to move towards the take-up reel, sharing the traction force requirement of the take-up reel. During the startup or acceleration stage, the traction wheels provide power in advance, reducing the instantaneous load of take-up motor 1 and extending the service life.

[0018] 4. For the cable core stranding device used in cable production, when the height of the cable wound on the take-up reel increases due to the increase in the amount of cable, the cable exerts an upward force on the traction wheels, and spring 2 is compressed under force. The frame drives the traction wheels to move upward along round rod 2. Conversely, when the cable height decreases, spring 2 resumes deformation and pushes the frame and the traction wheels to move downward. The floating frame supported by spring 2 enables the traction wheels to automatically lift with the increase in the diameter of the take-up reel, maintaining a constant contact pressure and avoiding insufficient pressure (slipping) or excessive pressure (crushing the cable).

[0019] V. For the cable core stranding device used in cable production, the rotating shaft four cooperates with the hexagonal rod of the traction wheel, and can still transmit torque when moving up and down in the frame, ensuring the continuous operation of the traction wheel. The limiting ring on the outer side of the swivel ring is embedded in the annular groove of the round sleeve, restricting the axial movement of the swivel ring and ensuring the stability of the whole-round process. The concave arc grooves of the pressure wheel and the traction wheel match the outer contour of the cable, increasing the contact area, dispersing the pressure, and reducing local wear. The depth of the arc groove one is shallower than that of the arc groove two, which can ensure an appropriate contact area between the pressure wheel and the cable core, evenly distribute the pressure, and avoid over-wrapping the cable core to restrict its free rotation or movement, optimizing the flexibility and adaptability of the whole-round process, and avoiding over-constraining the cable core. The deeper arc groove two can increase the contact arc length between the cable core and the traction wheel, enhance the traction reliability and power transmission efficiency, prevent slipping, and also reduce the lateral offset of the cable core during the conveying process, ensuring the stability of the linear movement.

[0020] VI. When stranding the cable core of this device, the motor two is used to drive the drive shaft, driving the turntable and the stranding plate fixedly connected thereto to rotate at the same angular velocity. The multi-strand copper wires on the wire pay-off reel are driven by the stranding plate and wind around each other according to a specific motion trajectory under the guidance of the threading holes, enabling the multi-strand copper wires to be evenly stranded, avoiding the loosening or uneven stranding of single-strand wires. The guiding ring restricts the direction of the stranded cable, avoiding swinging or twisting and making the stranding process smoother.

[0021] VII. The cable core stranding of this cable production uses a collaborative design of stranding-rounding-traction, optimizing energy consumption while improving the quality of the cable core. Its adaptive mechanism (spring pressurization, floating traction) ensures the stable production of the cable. The highly collaborative overall operation mode enables the device to efficiently and stably complete the cable core stranding process, improving production efficiency and product quality.

A gear three 92 and a synchronous pulley two 93 are respectively fixedly installed at both ends of the rotating shaft two 91.The second rotating shaft 91 movably penetrates through the two vertical plates 5.

A third rotating shaft 95 is rotatably installed in the rectangular shell 9. A fifth gear 96 and a fourth bevel gear 97 are fixedly installed on the third rotating shaft 95. The fourth bevel gear 97 meshes with the third bevel gear 94. A fourth rotating shaft 98 is rotatably installed in the rectangular shell 9. A sixth gear 99 meshing with the fifth gear 96 is fixedly installed on the fourth rotating shaft 98. A hexagonal groove is formed on the surface of the fourth rotating shaft 98. A hexagonal rod 84 is fixedly installed at the shaft end of the bottom of one side frame 8. The hexagonal rod 84 is slidably installed in the hexagonal groove. A first motor 14 for driving the wire reel 13 to rotate is installed on the bottom plate 1. A first bevel gear 16 is fixedly installed on the output shaft of the first motor 14. A first rotating shaft 15 is arranged on one side of the first motor 14. The first rotating shaft 15 is rotatably installed on the bottom plate 1. A second bevel gear 17 and a first synchronous pulley 18 are respectively fixedly installed at both ends of the first rotating shaft 15. The second bevel gear 17 meshes with the first bevel gear 16. A toothed synchronous belt 19 is sleeved on the first synchronous pulley 18 and the second synchronous pulley 93; Before using the device, the operator installs the multi-strand copper wires to be stranded on the wire reels 21 of the turntable 2 respectively. Then, each copper wire passes through the corresponding wire passing holes 31 on the stranding plate 3 in sequence. After the multi-strand copper wires converge, they pass through the guiding ring 42, completing the wire passing preparation work. After being ready, the first motor 14 and the second motor 4 are started simultaneously. The first motor 14 serves as the wire winding power source. The first bevel gear 16 on its output shaft rotates. By meshing with the second bevel gear 17, it drives the first rotating shaft 15 and the first synchronous pulley 18 to rotate, providing the basic power for subsequent transmission. The second motor 4 drives the drive shaft 41 to rotate. Since the drive shaft 41 is fixedly connected to the turntable 2 and the stranding plate 3 respectively, the turntable 2 and the stranding plate 3 rotate synchronously, starting the stranding process of the cable core; The second motor 4 drives the drive shaft 41 to rotate, driving the turntable 2 and the stranding plate 3 to rotate at the same angular velocity. At this time, the multi-strand copper wires on the wire reels 21 are driven by the stranding plate 3 and wind around each other along a specific movement track. The guiding ring 42 plays a role in guiding and restricting the copper wires, making the stranding process more stable and orderly, ensuring that the multi-strand copper wires can be stranded into a complete cable core according to the predetermined rules. The stranded cable core passes through the guiding ring 42 and enters the next processing link; The stranded cable core passes through the two U-shaped plates 7 in the rotating ring 6 in sequence. The two pressing wheels 71 in each group of U-shaped plates 7 are respectively distributed in the horizontal and vertical directions. The concave arc-shaped grooves 75 on their surfaces are adapted to the outer contour of the cable core, and can wrap and press the cable from multiple directions. The U-shaped plates 7 are connected to the inner wall of the rotating ring 6 through the first springs 73, endowing the pressing wheels 71 with a certain floating adjustment ability, and can automatically adjust the pressure according to the actual diameter and shape of the cable core, ensuring that the cable shape can be effectively corrected during the circularization process without damaging the cable surface; In the driving section of the take-up reel 13, the first motor 14 drives the first bevel gear 16 to rotate. Through the rotation of the second bevel gear 17, the first rotating shaft 15 and the first synchronous pulley 18, the second rotating shaft 91 rotates. The third gear 92 on the second rotating shaft 91 meshes with the toothed ring 61, thereby driving the rotating ring 6 to rotate around its axis. When the rotating ring 6 rotates, it drives the U-shaped plate 7 and the pressing wheel 71 to rotate around the cable core together. During the dynamic rotation process, the pressing wheel 71 continuously applies pressure to the cable core to complete the circular operation, so that the cable core maintains a good circular structure; The circularized cable core passes through the two traction wheels 81 in the frame 8. During the transmission process, when the second rotating shaft 91 rotates, the third bevel gear 94 on its surface drives the third rotating shaft 95 and the fifth gear 96 to rotate by meshing with the fourth bevel gear 97. The fifth gear 96 then meshes with the sixth gear 99 to drive the fourth rotating shaft 98 to rotate. The hexagonal groove formed on the surface of the fourth rotating shaft 98 cooperates with the hexagonal rod 84 at the bottom of the frame 8 to transmit the rotational motion of the fourth rotating shaft 98 to one of the traction wheels 81. Since the two traction wheels 81 are connected by the meshing second gear 82, the two traction wheels 81 will rotate synchronously, and the rotation direction is the same as the cable winding and conveying direction, providing additional conveying power for the cable core to ensure that the cable is more smooth during the conveying process; During the cable winding process, as the cable wound on the take-up reel 13 continuously increases, the overall diameter of the cable gradually increases, and the height of the take-up reel 13 will also rise accordingly. At this time, the frame 8 realizes adaptive adjustment through the elastic structure composed of the connecting block 86, the second round rod 87, the second spring 88 and the round block 85. When the second spring 88 is in the natural state, the two traction wheels 81 are in contact with the cable. When the height of the take-up reel 13 rises and drives the cable to move upward, the cable exerts an upward force on the traction wheel 81, and the second spring 88 is compressed by the force, causing the frame 8 to drive the traction wheel 81 to move upward along the second round rod 87. During this process, the elastic force generated by the second spring 88 ensures that the traction wheel 81 is always in close contact with the cable surface, providing sufficient friction to assist the cable conveying, and at the same time avoiding damaging the cable due to excessive pressure. The sliding fit between the hexagonal rod 84 and the hexagonal groove on the fourth rotating shaft 98 ensures that the traction wheel 81 can still rotate continuously during the up and down movement of the frame 8. When the cable winding on the take-up reel 13 is completed and the cable height drops, the second spring 88 resumes its deformation, pushing the frame 8 and the traction wheel 81 to move downward and re-contact with the cable, realizing the adaptive conveying of the device to the cable; The depth of the first arc-shaped groove 75 is shallower than that of the second arc-shaped groove 83, which can ensure an appropriate contact area between the pressing wheel 71 and the cable core. This can not only evenly distribute the pressure but also prevent over-wrapping the cable core and restricting its free rotation or movement, optimizing the flexibility and adaptability of the circularization process and avoiding over-constraining the cable core. The deeper second arc-shaped groove 83 can increase the contact arc length between the cable core and the traction wheel 81, enhancing the traction reliability and power transmission efficiency, preventing slippage, and reducing the lateral offset of the cable core during transportation, ensuring the stability of linear motion.

[0039] The working principle of this embodiment: First step: Before using the device, the operator installs the multi-strand copper wires to be stranded on the wire pay-off wheels 21 of the turntable 2 respectively. Then, each copper wire passes through the corresponding wire-passing holes 31 on the stranding plate 3 in sequence. After the multi-strand copper wires converge, they pass through the guiding ring 42 to complete the wire-passing preparation work. After getting ready, the first motor 14 and the second motor 4 are started simultaneously. The first motor 14 serves as the wire-receiving power source, and the bevel gear 16 on its output shaft rotates. By meshing with the bevel gear 17, it drives the first rotating shaft 15 and the first synchronous wheel 18 to rotate, providing the basic power for subsequent transmission. The second motor 4 drives the driving shaft 41 to rotate. Since the driving shaft 41 is fixedly connected to the turntable 2 and the stranding plate 3 respectively, the turntable 2 and the stranding plate 3 rotate synchronously, starting the stranding process of the cable core. Second step: The second motor 4 drives the driving shaft 41 to rotate, driving the turntable 2 and the stranding plate 3 to rotate at the same angular velocity. At this time, the multi-strand copper wires on the wire pay-off wheels 21 are driven by the stranding plate 3 to wind around each other along a specific motion trajectory. The guiding ring 42 plays a guiding and constraining role for the copper wires, making the stranding process more stable and orderly, ensuring that the multi-strand copper wires can be stranded into a complete cable core according to the predetermined rules. After stranding, the cable core passes through the guiding ring 42 and enters the next processing link. Third step: The stranded cable core passes through the two groups of U-shaped plates 7 in the rotating ring 6 in sequence. The two pressing wheels 71 in each group of U-shaped plates 7 are distributed in the horizontal and vertical directions respectively. The arc-shaped grooves 75 with concave surfaces on their surfaces are adapted to the outer contour of the cable core, and can wrap and press the cable from multiple directions. The U-shaped plates 7 are connected to the inner wall of the rotating ring 6 through the first springs 73, endowing the pressing wheels 71 with a certain floating adjustment ability, which can automatically adjust the pressure according to the actual diameter and shape of the cable core, ensuring that the cable shape can be effectively corrected during the circularization process without damaging the cable surface. Step 4: In the driving link of the take-up reel 13, the first motor 14 drives the first bevel gear 16 to rotate. Through the rotation of the second bevel gear 17, the first rotating shaft 15, and the first synchronous pulley 18, the second rotating shaft 91 rotates. The third gear 92 on the second rotating shaft 91 meshes with the toothed ring 61, thereby driving the rotating ring 6 to rotate around its axis. When the rotating ring 6 rotates, it drives the U-shaped plate 7 and the pressing wheel 71 to rotate around the cable core together. During the dynamic rotation process, the pressing wheel 71 continuously applies pressure to the cable core to complete the circular operation and keep the cable core in a good circular structure; Step 5: The circularized cable core passes through the two traction wheels 81 in the frame 8. During the transmission process, when the second rotating shaft 91 rotates, the third bevel gear 94 on its surface drives the third rotating shaft 95 and the fifth gear 96 to rotate by meshing with the fourth bevel gear 97. The fifth gear 96 then meshes with the sixth gear 99 to drive the fourth rotating shaft 98 to rotate. The hexagonal groove formed on the surface of the fourth rotating shaft 98 cooperates with the hexagonal rod 84 at the bottom of the frame 8 to transmit the rotational motion of the fourth rotating shaft 98 to one of the traction wheels 81. Since the two traction wheels 81 are connected by the meshing second gear 82, the two traction wheels 81 will rotate synchronously, and the rotation direction is the same as the cable winding and conveying direction, providing additional conveying power for the cable core to ensure smoother cable conveyance during the process; Step 6: During the cable winding process, as the cable wound on the take-up reel 13 continuously increases, the overall diameter of the cable gradually increases, and the height of the take-up reel 13 will also rise accordingly. At this time, the frame 8 realizes adaptive adjustment through the elastic structure composed of the connecting block 86, the second round rod 87, the second spring 88, and the round block 85. When the second spring 88 is in its natural state, the two traction wheels 81 are in contact with the cable. When the rising height of the take-up reel 13 drives the cable to move upward, the cable applies an upward force to the traction wheels 81, and the second spring 88 is compressed by the force, causing the frame 8 to drive the traction wheels 81 to move upward along the second round rod 87. During this process, the elastic force generated by the second spring 88 ensures that the traction wheels 81 always remain in close contact with the cable surface, providing sufficient friction to assist in cable conveyance, while also avoiding damaging the cable due to excessive pressure. The sliding fit between the hexagonal rod 84 and the hexagonal groove on the fourth rotating shaft 98 ensures that the traction wheels 81 can still rotate continuously during the up and down movement of the frame 8. When the cable winding on the take-up reel 13 is completed and the cable height drops, the second spring 88 recovers its deformation, pushing the frame 8 and the traction wheels 81 to move downward to re-contact the cable, realizing the adaptive conveyance of the device for the cable; Step 7: The depth of the first arc-shaped groove 75 is shallower than that of the second arc-shaped groove 83, which can ensure an appropriate contact area between the pressing wheel 71 and the cable core. This can not only evenly distribute the pressure but also avoid over-wrapping the cable core, restricting its free rotation or movement, optimizing the flexibility and adaptability of the circularizing process, and avoiding over-constraining the cable core. The deeper second arc-shaped groove 83 can increase the contact arc length between the cable core and the traction wheel 81, enhance the traction reliability and power transmission efficiency, prevent slipping, and also reduce the lateral offset of the cable core during the conveying process, ensuring the linear motion stability. Step 8: Under the collaborative work of the above-mentioned components, after the cable core undergoes stranding, circularizing, and auxiliary conveying, it is finally wound by the take-up reel 13. The first motor 14 continuously drives the take-up reel 13 to rotate. As the take-up reel 13 rotates, the cable core is neatly wound around the take-up reel 13. Throughout the process, each part of the device cooperates with each other to maintain the tension stability of the cable core and ensure the winding quality until the stranding process of the cable core is completed.
