Description

Technical Field

[0001] This utility model relates to the field of cable production technology, specifically to a cable stranding device for cable production. Background Technology

[0002] Cables are wires with insulation and protective sheaths. They are usually quite thick and consist of multiple insulated conductors. They are often laid overhead or buried underground or underwater for telecommunications or power transmission.

[0003] In the cable production process, the stranding process is a crucial step in forming a cable core by twisting multiple insulated conductors according to specific rules. This directly affects the electrical performance, mechanical strength, and service life of the cable. After stranding the cable, the stranding equipment needs to rewind it. Traditional stranding equipment mostly uses a single winding roller to rewind the cable. Due to the lack of an effective guiding and wire arrangement adjustment structure, the cable is prone to uneven arrangement during the winding process, which affects subsequent processing and use, resulting in insufficient practicality. Therefore, it is necessary to redesign a cable stranding equipment for cable production to address the above problems. Utility Model Content

[0021] This utility model provides a technical solution for cable stranding equipment used in cable production:

[0022] Please see Figures 1-5 A cable stranding device for cable production includes a base 1. A bearing 3 is fixedly mounted on the upper surface of the base 1 via a support plate 2. A fixing sleeve 4 is fixedly mounted on the inner ring of the bearing 3. A connecting block 6 is fixedly mounted on the inner wall of the fixing sleeve 4 via a fixing mechanism. Multiple first connecting frames 7 are fixedly mounted on the outer wall of the connecting block 6. Multiple second connecting frames 9 are fixedly connected to the inner wall of the fixing sleeve 4 via a telescopic mechanism. A clamping roller 10 is rotatably mounted inside each first connecting frame 7 and each second connecting frame 9. A toothed ring 11 is fixedly mounted on the outer wall of the fixing sleeve 4. A first motor 12 is fixedly mounted on the outer wall of the support plate 2. The outer wall of the output shaft of the first motor 12 is rotated... The mechanism is connected to the gear ring 11. A rotating shaft is rotatably mounted on the upper end face of the base 1 via a connecting plate 14. A second motor 16 connected to the rotating shaft is fixedly mounted on the outer wall of the connecting plate 14. A winding roller 15 is fixedly mounted on the outer wall of the rotating shaft. A reciprocating screw 18 is rotatably mounted on the upper end face of the base 1 via a moving frame 17. A third motor 19 connected to the reciprocating screw 18 is fixedly mounted on the outer wall of the moving frame 17. A screw sleeve 21 is rotatably mounted on the outer wall of the reciprocating screw 18. A limit rod 20 is fixedly mounted inside the moving frame 17. The limit rod 20 slides through the screw sleeve 21. A guide sleeve 23 is fixedly mounted on the upper end face of the screw sleeve 21 via a connecting mechanism.

[0023] The fixing mechanism includes multiple fixing rods 5 fixedly installed on the inner wall of the fixing sleeve 4, and the end of each fixing rod 5 is fixedly connected to the outer wall of the connecting block 6.

[0024] Furthermore, the fixing rod 5 is made of high-strength alloy material, which has good load-bearing capacity and anti-deformation performance, and can stably support the connecting block 6 and the first connecting frame 7, ensuring that the connecting block 6 will not shake during the twisting process.

[0025] The telescopic mechanism includes multiple electric push rods 8 fixedly installed on the inner wall of the fixed sleeve 4, and the telescopic end of each electric push rod 8 is fixedly connected to the outer wall of the corresponding second connecting frame 9.

[0026] Furthermore, the extension and retraction stroke of the electric actuator 8 can be precisely controlled by the controller 25, and the spacing between the clamping rollers 10 can be flexibly adjusted according to the diameter of different wires, thus adapting to a wider range.

[0027] The rotating mechanism includes a gear 13 fixedly mounted on the outer wall of the output shaft of the first motor 12, and the gear 13 meshes with the gear ring 11.

[0028] Furthermore, the tooth surfaces of gear 13 and gear ring 11 are precision machined, resulting in a small meshing gap and high transmission efficiency, which enables the fixed sleeve 4 to rotate smoothly and ensures the stability of the twisting process.

[0029] The connecting mechanism includes a connecting rod 22 fixedly installed on the upper end face of the lead screw sleeve 21, and the end of the connecting rod 22 is fixedly connected to the outer wall of the guide sleeve 23.

[0030] Furthermore, the connecting rod 22 is fixed to the lead screw sleeve 21 and the guide sleeve 23 by welding, which has high connection strength and will not fall off when the guide sleeve 23 reciprocates, ensuring that the wiring work is carried out normally.

[0031] A controller 25 is fixedly mounted on the upper surface of the base 1 via a mounting plate 24. The controller 25 is electrically connected to each electric push rod 8, the first motor 12, the second motor 16, and the third motor 19.

[0032] Furthermore, the controller 25 is equipped with a touch panel, allowing operators to intuitively set the operating parameters of each component. It also has a fault alarm function, which can promptly remind staff to handle equipment malfunctions.

[0033] Multiple wires are passed through the two opposing clamping rollers 10. The electric push rod 8 is activated by the controller 25 on the base 1. The telescopic end of the electric push rod 8 pushes the second connecting frame 9 closer to the first connecting frame 7 until the clamping rollers 10 on both sides clamp the wires. At this time, a stable clamping force is formed between the clamping rollers 10 and the wires, which can ensure that the wires do not slip during the twisting process and reduce frictional damage to the surface of the wires through the rotation of the clamping rollers 10. After the wires are clamped, the first motor 12 is activated by the controller 25. The output shaft of the first motor 12 drives the gear 13 to rotate. The gear 13 meshes with the toothed ring 11 on the outer wall of the fixed sleeve 4, thereby driving the inner ring of the bearing 3 on the support plate 2 of the fixed sleeve 4 to rotate.

[0034] When the fixed sleeve 4 rotates, the connecting block 6 connected inside it by the fixed rod 5 rotates synchronously, and the first connecting frame 7 on the outer wall of the connecting block 6 rotates together. At the same time, the electric push rod 8 and the second connecting frame 9 also move in a circular motion with the fixed sleeve 4. During the rotation, the multiple sets of clamping rollers 10 drive the multiple strands of wires passing through them to be twisted around the central axis of the fixed sleeve 4 to form a cable core that meets the specifications. After stranding, the cable core needs to pass through the guide sleeve 23 and then be fixed to the winding roller 15. At this time, the second motor 16 and the third motor 19 are started. The output shaft of the second motor 16 drives the rotating shaft to rotate, and the rotating shaft drives the winding roller 15 to rotate synchronously, starting to wind the stranded cable. At the same time, the third motor 19 drives the reciprocating screw 18 in the moving frame 17 to rotate. Under the action of the thread of the reciprocating screw 18, the screw sleeve 21 moves horizontally back and forth along the limit rod 20. The guide sleeve 23 connected to the upper end of the screw sleeve 21 through the connecting rod 22 moves synchronously, so that the cable is evenly distributed in the axial direction of the winding roller 15 during the winding process, avoiding stacking or loose arrangement.

[0035] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
