[0022] Reference Figure 1 to Figure 6 The present embodiment proposes a high-speed stranding machine for low-voltage cable production, which is used for stranding core wires into stranded wires, including a main turntable 1, which is rotatably arranged, has a first wire hole 101 in the center, and has first guide grooves 102 around it, the first guide grooves 102 are along the radial direction of the main turntable 1, and are arranged in a plurality of circles, and the first guide grooves 102 have an inlet and outlet 103 at one end away from the first wire hole 101; a first sub-turntable 2 is rotatably and slidably arranged in the first guide groove 102, and the rotation axis of the first sub-turntable 2 is parallel to the rotation axis of the main turntable 1; a stranded wire reel 3 is arranged on the first sub-turntable 2, and the stranded wire reel 3 is used to install the stranded wire, and the rotation axis of the stranded wire reel 3 is perpendicular to the rotation axis of the first sub-turntable 2.

[0023] In this embodiment, the main turntable 1 is the basic component of the entire device, and its rotation setting realizes stable rotation through an external drive motor and a transmission mechanism. The first wire hole 101 in the center of the main turntable 1 is used to allow the core wire to pass through, providing a fixed passing path for the core wire, ensuring that the core wire is in a stable position during the stranding process, so as to ensure that the core wire does not deviate during high-speed stranding, thereby improving the precision and quality of the stranding.

[0024] The first guide grooves 102 around the main turntable 1 are distributed radially and arranged circumferentially, providing accurate sliding and rotating tracks for the first sub-turntable 2, so that the first sub-turntable 2 can move according to the preset track. Thereby, the orderly layout and coordinated work of multiple first sub-turntables 2 are realized, and the space utilization and work efficiency of the equipment are improved. The inlet and outlet 103 is set at one end of the first guide groove 102 away from the first line hole, which is convenient for the first sub-turntable 2 to enter and exit, and to facilitate the replacement of the first sub-turntable 2.

[0025] The first sub-turntable 2 can rotate and slide in the first guide groove 102. Its rotation axis is parallel to the rotation axis of the main turntable. The design principle is to achieve rapid position switching through relative rotation and sliding. The technical effect is to quickly move the new twisted wire coil 3 to the working position without stopping the machine, thereby improving the continuity of production. The twisted wire coil 3 is installed on the first sub-turntable 2, and its rotation axis is perpendicular to the rotation axis of the first sub-turntable 2. The design principle is to enable the twisted wire to be stably released and participate in the twisting process. The technical effect is to ensure the uniformity and tightness of the twisted wire.

[0026] In this embodiment, when the equipment is running, the core wire passes through the first wire hole 101 in the center of the main turntable 1, and the stranded wire reels 3 on the multiple first sub-turntables 2 release the stranded wires at the same time to process the stranded wires on the core wire. When the stranded wire reel 3 on a first sub-turntable 2 is about to run out, the main turntable 1 is rotating, and the first sub-turntable 2 with the new stranded wire reel 3 is quickly moved to the stranding working position through the sliding and rotation of the first sub-turntable 2 in the first guide groove 102, and the stranding operation is continued to achieve uninterrupted production.

[0027] In this embodiment, the above structure and working principle effectively solve the problem of low efficiency of replacing wire coils and affecting processing efficiency in the prior art high-speed stranding machine. The wire coil 3 can be quickly replaced without stopping the machine, which greatly improves production efficiency, ensures the quality and stability of the stranded wire, reduces production costs, and meets the production needs of low-voltage cables of different specifications.

[0028] Furthermore, it also includes a storage disk 4, which is arranged outside the main turntable 1 and has a feeding guide groove 401 and a receiving guide groove 402. The feeding guide groove 401 has a feeding port 403 at one end close to the first line hole 101, and the receiving guide groove 402 has a receiving port 404 at one end close to the first line hole 101. The feeding guide groove 401 and the receiving guide groove 402 are arranged circumferentially alternately in sequence. The second sub-disc 5 is rotatably and slidably arranged in the feeding guide groove 401 , the rotation axis of the second sub-disc 5 is parallel to the rotation axis of the first sub-disc 2 , and the second sub-disc 5 is also provided with a twisted wire coil 3 .

[0029] Furthermore, it also includes a movable baffle 14, which is movably set at the feeding port 403 and the receiving port 404, and blocks or cancels blocking the feeding port 403 and the receiving port 404 after movement. The movable baffle 14 blocks the feeding port 403 and the receiving port 404 to achieve isolation from the inlet and outlet 103.

[0030] In this embodiment, the storage disk 4 is located outside the main turntable 1, and the feeding guide groove 401 and the receiving guide groove 402 are arranged in a staggered manner in a circle. The design principle is to realize the orderly feeding and receiving of materials through a reasonable spatial layout. The feeding port 403 and the receiving port 404 are respectively located at one end of the feeding guide groove 401 and the receiving guide groove 402 close to the first line hole 101, so as to facilitate docking with the inlet and outlet 103 on the main turntable 1.

[0031] The second sub-disc 5 is rotatably and slidably arranged in the feeding guide groove 401, and its rotation axis is parallel to the rotation axis of the first sub-disc 2. The design purpose is to ensure that the second sub-disc 5 can move flexibly and accurately interact with the main disc 1. The movable baffle 14 is movably arranged at the feeding port 403 and the receiving port 404. Its working principle is that when feeding or receiving operation is required, the movable baffle 14 moves to cancel the blocking of the corresponding port, so that the second sub-disc 5 can smoothly enter and exit; when no operation is required, the movable baffle 14 blocks the feeding port 403 and the receiving port 404 to achieve isolation from the inlet and outlet 103.

[0032] In terms of technical effects, the cooperation between the storage disk 4 and the second sub-rotating disk 5 increases the storage and replacement efficiency of the spare twisted wire coil 3. The setting of the movable baffle 14 improves the safety of operation, prevents accidental wire coil entry and exit during the twisting process, and ensures the stability of the twisting operation.

[0033] Overall working principle: During the wire twisting process, when the wire reel 3 of a first sub-rotor disc 2 on the main turntable 1 is about to run out, the movable baffle 14 moves to open the receiving port 404, and the first sub-rotor disc 2 that has run out of wire reels enters the receiving guide groove 402 through the receiving port 404; thereafter, the movable baffle 14 moves to open the feeding port 403, and the second sub-rotor disc 5 equipped with a new wire reel 3 enters the first guide groove 102 of the main turntable 1 from the feeding guide groove 401 through the feeding port 403, thereby replacing the first sub-rotor disc 2 that has run out of wire reels. The entire replacement process of the second sub-rotor disc 5 can be carried out when the wire twisting is stopped, or it can be carried out during the wire twisting process, which can be selected according to actual needs. Through the synergistic effect of the above-mentioned components, the problem of rapid replacement and safe operation of the wire reels 3 during the wire twisting process is effectively solved, the production efficiency is improved, and the product quality and production continuity are guaranteed.

[0034] Furthermore, it also includes a first elastic member 6, which is arranged in the first guide groove 102, one end of which acts on the first sub-turntable 2, and the other end acts on the bottom of the first guide groove 102, so as to provide a force for the first sub-turntable 2 to approach the inlet and outlet 103; the second elastic member 7 is arranged in the feeding guide groove 401, one end of which acts on the second sub-turntable 5, and the other end acts on the bottom of the feeding guide groove 401, so as to provide a force for the second sub-turntable 5 to approach the feeding port 403.

[0035] In this embodiment, the first elastic member 6 is arranged in the first guide groove 102. The design principle is to use elastic restoring force to provide the first sub-disc 2 with a force close to the inlet and outlet 103. In actual work, when the first sub-disc 2 is in the first guide groove 102, the first elastic member 6 is compressed, and when the movable baffle 14 stops blocking the receiving port 404, the elastic force of the first elastic member 6 will push the first sub-disc 2 to pass through the inlet and outlet 103 and the receiving port 404, so that the first sub-disc 2 that has used up the strands is sent to the receiving guide groove 402 to achieve exchange.

[0036] The second elastic member 7 is arranged in the feeding guide groove 401. Its working principle is similar to that of the first elastic member 6, and it provides a force for the second sub-disc 5 to approach the feeding port 403. This helps to ensure that the second sub-disc 5 maintains an appropriate position in the feeding guide groove 401. When the feeding operation is required, the movable baffle 14 is operated to cancel the blocking of the inlet and outlet 103, and the elastic force of the second elastic member 7 will push the second sub-disc 5 through the feeding port 403 and the inlet and outlet 103, so that the second sub-disc 5 that has run out of strands is sent to the first guide groove 102 to achieve exchange. In terms of technical effects, the arrangement of the first elastic member 6 and the second elastic member 7 improves the position stability and response speed of the sub-disc, reduces exchange failures caused by inaccurate position, and improves the working efficiency and reliability of the stranding machine.

[0037] Overall working principle: During normal wire twisting, the first elastic member 6 and the second elastic member 7 respectively keep the first sub-rotating disc 2 and the second sub-rotating disc 5 at the predetermined positions. When the wire coil needs to be replaced, the movable baffle 14 is operated to remove the blocking of the feeding port 403 and the receiving port 404. Under the action of the elastic member, the first sub-rotating disc 2 and the second sub-rotating disc 5 quickly complete the position exchange, realizing efficient coil replacement.

[0038] Overall technical effect: Through the synergistic effect of the first elastic member 6 and the second elastic member 7, the wire coil replacement mechanism of the stranding machine is further optimized, the continuity and stability of production are improved, and the efficient production of low-voltage cables is ensured.

[0039] Furthermore, the first elastic member 6 is used to push the first sub-turntable 2 in the first guide groove 102 into the receiving guide groove 402, and the second elastic member 7 is used to push the second sub-turntable 5 in the feeding guide groove 401 into the first guide groove 102; the stiffness coefficient of the second elastic member 7 is greater than the progress coefficient of the first elastic member 6.

[0040] Furthermore, it also includes a first arc-shaped push plate 10 , which is arranged between the first elastic member 6 and the first sub-turntable 2 ; and a second arc-shaped push plate 11 is arranged between the second elastic member 7 and the second sub-turntable 5 .

[0041] In this embodiment, the first arc-shaped push plate 10 is arranged between the first elastic member 6 and the first sub-turntable 2. The design principle is to more evenly transfer the thrust of the first elastic member 6 to the first sub-turntable 2 through the arc shape, thereby reducing the local uneven force and wear caused by the thrust concentration. The second arc-shaped push plate 11 is arranged between the second elastic member 7 and the second sub-turntable 5, and its working principle is the same as that of the first arc-shaped push plate 10. In actual work, when the first elastic member 6 or the second elastic member 7 is compressed or stretched, the elastic force generated by it acts more smoothly on the corresponding sub-turntable through the first arc-shaped push plate 10 or the second arc-shaped push plate 11. In terms of technical effects, the setting of the first arc-shaped push plate 10 and the second arc-shaped push plate 11 improves the uniformity and stability of the thrust transmission of the elastic member, reduces the wear of the sub-turntable, and extends the service life of the equipment.

[0042] Overall working principle: During the operation of the stranding machine, as the elastic member expands and contracts, the first arc-shaped push plate 10 and the second arc-shaped push plate 11 respectively apply elastic force evenly to the first sub-turntable 2 and the second sub-turntable 5, thereby achieving precise movement and position adjustment of the sub-turntables.

[0043] Overall technical effect: Through the setting of these two arc-shaped push plates, the stress conditions of the internal components of the stranding machine are further optimized, the operating stability and reliability of the equipment are improved, and it is helpful to ensure the long-term stable production of low-voltage cables.

[0044] Furthermore, it also includes a wire end disk 8, which is arranged on one side of the main turntable 1 and is located downstream of the main turntable 1 along the core wire conveying direction, and has a second wire hole 801 in the middle of the wire end disk 8; a plurality of clamps 9 are arranged in a circle on the wire end disk 8, and are used to clamp the wire ends of the stranded wire; one end of the third elastic member 12 acts on the clamp 9, and the other end acts on the wire end disk 8, providing a force to keep the clamp 9 away from the second wire hole 801.

[0045] In this embodiment, the wire end disk 8 is arranged on the downstream side of the main turntable 1 along the core wire conveying direction. Its design principle is to provide an installation position for the chuck 9, and to guide and organize the ends of the stranded wires in the overall structure. There are several chucks 9, which are arranged in a circle on the wire end disk 8. The chuck 9 itself has the ability to independently clamp the ends of the stranded wires. Its design principle is to be able to firmly grasp the ends of the stranded wires through the clamping structure and the clamping force design. One end of the third elastic member 12 acts on the chuck 9, and the other end acts on the wire end disk 8. Its working principle is that when the chuck 9 clamps the ends of the stranded wires, the third elastic member 12 provides a force to keep it away from the second wire hole 801.

[0046] In actual operation, the chuck 9 clamps the ends of the stranded wires, and then, under the action of the third elastic member 12, moves the ends of the stranded wires as a whole away from the second wire hole 801. This can prevent the ends of the stranded wires from getting entangled near the second wire hole 801 during the subsequent stranding process. For example, before the stranding begins, the chuck 9 accurately clamps the ends of the stranded wires. As the third elastic member 12 is stretched, the chuck 9 moves the ends of the wires to a safe position. During the entire stranding process, the chuck 9 always keeps the ends of the stranded wires clamped, and under the action of the third elastic member 12, it maintains a state away from the second wire hole 801, ensuring the smooth progress of the stranding work. In terms of technical effects, the independent clamping ability of the chuck 9 ensures the stability and reliability of the wire end clamping. The cooperation between the third elastic member 12 and the chuck 9 effectively avoids the problem of wire end entanglement and improves the quality and efficiency of the stranded wires.

[0047] Overall working principle: When the stranded wire needs to be replaced, the clamp 9 clamps the stranded wire end, and then moves away from the second wire hole 801 under the action of the third elastic member 12. During the stranding operation of the main turntable 1 and other components, the clamp 9 remains away. Overall technical effect: Through the synergistic effect of the above components, the stability and reliability of the production of low-voltage cable strands are significantly improved, and the stranding failure caused by the entanglement of the wire ends is effectively avoided, ensuring product quality and production efficiency.

[0048] Furthermore, the clamping head 9 is slidably arranged on the thread head disk 8 , and the sliding direction is along the radial direction of the thread head disk 8 .

[0049] In this embodiment, the clamp 9 is slidably arranged on the wire head disk 8, and the sliding direction is along the radial direction of the wire head disk 8. This sliding design makes the clamping function of the clamp 9 more perfect and efficient, and can ensure that it is sufficiently away from the second wire hole 801, thereby improving the stability and reliability of the production of low-voltage cable strands, effectively avoiding stranding failures caused by wire entanglement, and ensuring product quality and production efficiency.

[0050] Furthermore, the chuck 9 has an outer conical surface 901 and also includes a sliding push piece 13. The sliding push piece 13 is slidably arranged on the wire head disk 8, and the sliding direction is along the axial direction of the core wire. The sliding push piece 13 has an inner conical surface 1301, and the outer conical surface 901 abuts against the inner conical surface 1301. After the sliding push piece 13 slides, it pushes the chuck 9 close to the second wire hole 801.

[0051] In this embodiment, the chuck 9 has an outer conical surface 901, and the sliding push piece 13 is slidably arranged on the thread head disk 8, and the sliding direction is along the axial direction of the core wire. The design principle is to utilize the cooperation between the outer conical surface 901 and the inner conical surface 1301. When the sliding push piece 13 slides along the axial direction of the core wire, the outer conical surface 901 is pushed by the inner conical surface 1301, so that the chuck 9 moves along the radial direction of the thread head disk 8, and realizes the action of approaching or moving away from the second thread hole 801.

[0052] In actual work, when the chuck 9 needs to approach the second wire hole 801 for clamping operation, the sliding push piece 13 slides along the axial direction of the core wire, and its internal conical surface 1301 interacts with the outer conical surface 901 of the chuck 9 to push the chuck 9 to move toward the second wire hole 801. For example, when the stranded wire needs to approach the core wire and twist with the core wire, the sliding push piece 13 slides and pushes the chuck 9 to approach the second wire hole 801. After the chuck 9 clamps the wire end, the sliding push piece 13 slides in the opposite direction. Under the action of the third elastic member 12, the chuck 9 takes the wire end away from the second wire hole 801. In terms of technical effect, this design of tapered surface matching makes the movement of the chuck 9 more precise and stable, and improves the accuracy and reliability of the adjustment operation.

[0053] Overall working principle: During the stranding process, the sliding of the sliding push piece 13 is controlled as needed to achieve the clamping and position adjustment of the clamp 9, and work in coordination with other components to ensure the smooth stranding. Overall technical effect: Through this ingenious structural design, the operating performance of the clamp 9 is further optimized, and the efficiency and quality of the production of low-voltage cable strands are improved.

[0054] Furthermore, the chuck 9 includes a first clamping portion 902, which is slidably disposed on the wire end disk 8, and the sliding direction is along the radial direction of the wire end disk 8; the second clamping portion 903 is slidably disposed on the first clamping portion 902, and a clamping space is formed between the second clamping portion 903 and the first clamping portion 902, and the clamping space is used to clamp the wire ends of the stranded wire; one end of the fourth elastic member 904 acts on the second clamping portion 903, and the other end acts on the first clamping portion 902, providing a force for the second clamping portion 903 to clamp the wire ends of the stranded wire close to the first clamping portion 902.

[0055] In this embodiment, the chuck 9 includes a first clamping portion 902 and a second clamping portion 903. The first clamping portion 902 is slidably disposed on the wire head disk 8, and the sliding direction is along the radial direction of the wire head disk 8. The design principle is to adjust the position of the chuck as a whole on the wire head disk 8 by sliding in the radial direction, so as to better align and clamp the ends of the stranded wires. The second clamping portion 903 is slidably disposed on the first clamping portion 902, and a clamping space is formed between the second clamping portion 903 and the first clamping portion 902. The working principle is to change the size of the clamping space by relative sliding, thereby achieving the clamping and loosening of the ends of the stranded wires. One end of the fourth elastic member 904 acts on the second clamping portion 903, and the other end acts on the first clamping portion 902. Its function is to provide the second clamping portion 903 with a force to clamp the ends of the stranded wires close to the first clamping portion 902.

[0056] In actual operation, when it is necessary to clamp the end of the twisted wire, first the first clamp 902 slides to a suitable position along the radial direction of the wire end disk 8 so that the clamping space is aligned with the wire end. Then, the external force overcomes the elastic force of the fourth elastic member 904, causing the second clamp 903 to slide relative to the first clamp 902, expanding the clamping space and allowing the wire end to enter. After the wire end enters, the external force disappears, and the elastic force of the fourth elastic member 904 causes the second clamp 903 to quickly approach the first clamp 902, clamping the wire end in the clamping space. In terms of technical effects, the sliding design of the first clamp 902 and the second clamp 903 and the cooperation of the fourth elastic member 904 enable the clamp 9 to clamp the wire end more flexibly and accurately, thereby improving the stability and reliability of the clamping.

[0057] Overall working principle: During the stranding process, the various components of the clamp 9 work together to achieve fast and stable clamping of the stranded wire ends, ensuring the smooth progress of the stranding work. Overall technical effect: Through the design of this clamp structure, the working efficiency and stranding quality of the low-voltage cable high-speed stranding machine are further improved, and production problems caused by unstable clamping of the wire ends are reduced.
