Description

Technical Field

[0001] This utility model belongs to the field of cable stranding technology, and more specifically, it relates to a cable stranding machine. Background Technology

[0002] Cable stranding machines are one of the core pieces of equipment in the cable manufacturing industry. Their main function is to wind and integrate multiple independent copper wires (or other conductive metal wires) according to preset stranding rules (such as pitch and direction) to form a cable core with specific mechanical strength, conductivity and flexibility, laying the foundation for the subsequent covering of cable insulation and sheath layers.

[0003] Traditional cable stranding machines often use bolts or complex snap-fit ​​structures to fix the pay-off reel. Replacing the pay-off reel requires disassembling each component one by one using tools such as wrenches. This makes the installation and removal of the pay-off reel cumbersome and inconvenient. Therefore, this paper studies and improves the existing structure to provide a cable stranding machine with greater practical value. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a cable stranding machine, which is achieved by the following specific technical means: A cable stranding machine includes a frame, a second support, and a third support. A turntable is rotatably mounted inside the second support. Several mounting shafts are equidistantly mounted on the turntable's circumference, and each mounting shaft is equipped with a wire feeding reel. A stranding reel is rotatably mounted inside the third support. The surface of the stranding reel has equidistant wire-passing holes matching the number of wire feeding reels. A guide ring is provided on the rear side of the third support. A connecting shaft is fixedly connected to the center of the turntable, and each mounting shaft has a fixedly fitted front end with a... A retaining ring one is provided, and a retaining ring two is movably sleeved on the front end of each of the mounting shafts. A central hole is provided in the middle of the surface of the pay-off reel. The pay-off reel is sleeved on the mounting shaft through the central hole and is located between the retaining ring one and the retaining ring two. A locking block is fixedly installed on the hole wall of the retaining ring two. A sliding groove is provided on the rear surface of the mounting shaft. An arc-shaped groove is provided on the side wall of the sliding groove. The locking block is movably inserted into the sliding groove and rotated into the arc-shaped groove. A limiting block for limiting the locking block is slidably installed in the sliding groove.

[0005] Furthermore, bracket two, bracket three and guide ring are all fixedly installed on the upper end of the frame, bracket one is provided on the rear side of the frame, bracket one is fixedly installed on the upper end of the frame, and a take-up roller is rotatably installed inside bracket one.

[0006] Furthermore, a drive device is fixedly installed on the frame, and the output shaft of the drive device is fixedly connected to the center of the turntable to drive the turntable to rotate.

[0007] Furthermore, the turntable is equidistantly equipped with a number of guide wheels that are the same number as the wire feeding reels.

[0008] Furthermore, a limiting groove is formed on the surface of the limiting block, an L-rod is fixedly connected to the bottom end of the limiting block, the L-rod moves through the interior of the mounting shaft, a spring is fixedly connected between the L-rod and the inner wall of the mounting shaft, and a pressing plate is fixedly connected to the rear end of the L-rod.

[0009] Furthermore, both sides of the first and second retaining rings are provided with a number of balls at equal intervals.

[0010] Compared with the prior art, the present invention has the following beneficial effects: 1. This cable stranding machine achieves rapid fixing and disassembly of the pay-off reel by using the locking block of the retaining ring two in conjunction with the sliding groove and arc groove of the mounting shaft, combined with the elastic limiting structure of the limiting block: During installation, simply insert the locking block of the retaining ring two into the sliding groove and rotate it into the arc groove. The limiting block will automatically reset under the action of the spring, and the limiting groove will limit the locking block, thus fixing it without tools. During disassembly, pressing the pressing plate will move the L rod to release the constraint of the limiting block on the locking block. Reversing and pulling out the retaining ring two will remove the pay-off reel, shortening the pay-off reel replacement time and making operation more convenient. Both sides of the retaining ring one and retaining ring two are equipped with several balls. When the pay-off reel rotates on the mounting shaft to pay off the wire, the balls can convert the sliding friction between the pay-off reel and the retaining ring into rolling friction, reducing frictional resistance.

[0011] 2. The turntable and the stranding disc are fixedly connected by a connecting shaft and driven by the same drive device, which ensures that they rotate at the same angular velocity, avoiding disorder in the stranding of multiple copper wires. The number of wire-passing holes on the stranding disc is the same as that on the pay-off disc and they are equidistantly distributed around the circumference, which can ensure that the multiple copper wires are evenly distributed. The guide ring on the rear side further constrains and guides the stranded cable core, effectively improving the uniformity of the cable stranding density. Attached Figure Description

[0021] Example:

[0022] As attached Figure 1 To be continued Figure 5 As shown: This utility model provides a cable stranding machine, including a frame 1, a second support 2, and a third support 3. A turntable 4 is rotatably installed inside the second support 2. Several mounting shafts 5 are equidistantly installed on the circumference of the turntable 4. Each mounting shaft 5 is equipped with a wire feeding reel 41. A stranding reel 31 is rotatably installed inside the third support 3. The surface of the stranding reel 31 is provided with wire passing holes 32 at equal intervals around its circumference, the same number as the number of wire feeding reels 41. A guide ring 13 is provided on the rear side of the third support 3. A connecting shaft 12 is fixedly connected to the middle of the turntable 4 and the stranding reel 31. A retaining ring 51 is fixedly sleeved on the front end of each mounting shaft 5. A retaining ring 6 is movably sleeved on the front end of each mounting shaft 5. A central hole is provided in the middle of the surface of the wire feeding reel 41. The wire feeding reel 41 is sleeved on the mounting shaft 5 through the central hole and is located between the retaining ring 51 and the retaining ring 6, which limits the wire feeding reel 41 and prevents it from detaching. A locking block 61 is fixedly installed on the hole wall of the retaining ring 2 6. A sliding groove 52 is opened on the rear side surface of the mounting shaft 5. An arc groove is opened on the side wall of the sliding groove 52. The locking block 61 is movably inserted into the sliding groove 52 and rotated into the arc groove. A limiting block 7 is slidably installed in the sliding groove 52 to limit the locking block 61, so as to prevent the locking block 61 from falling out of the arc groove and ensure the stability of the locking and fixing. Support 2, support 3 and guide ring 13 are all fixedly installed on the upper end of frame 1. Support 14 is provided on the rear side of frame 1. Support 14 is fixedly installed on the upper end of frame 1. A take-up roller 15 is rotatably installed inside support 14 for winding the twisted cable. A drive device 11 is fixedly installed on the frame 1. The output shaft of the drive device 11 is fixedly connected to the middle of the turntable 4 to drive the turntable 4 to rotate, ensuring that the two rotate at the same angular velocity to avoid the multiple strands of copper wire from twisting and becoming disordered. Several guide wheels 42, the same number as the wire feeding disc 41, are installed equidistantly around the circumference of the turntable 4, which guide the copper wire. The surface of the limiting block 7 has a limiting groove 71. The bottom end of the limiting block 7 is fixedly connected to an L rod 8. The L rod 8 moves through the inside of the mounting shaft 5. A spring 81 is fixedly connected between the L rod 8 and the inner wall of the mounting shaft 5. A pressing plate 82 is fixedly connected to the rear end of the L rod 8 for easy pressing. Both the first retaining ring 51 and the second retaining ring 6 have several balls 9 evenly spaced on their opposite sides to reduce friction.

[0023] The working principle of this embodiment: Step 1: In use, first install multiple cable reels 41 wound with cables onto the mounting shaft 5. During installation, the cable reels 41 are fitted onto the mounting shaft 5 through the center hole. Then, the retaining ring 6 is fitted onto the mounting shaft 5, and the locking block 61 is inserted into the slide groove 52. The locking block 61 will exert a force on the limiting block 7 in the slide groove 52. The limiting block 7 moves under force, and the spring 81 is compressed. When the limiting block 7 is in contact with the side wall of the slide groove 52, the limiting block 7 no longer blocks the opening of the arc groove. At this time, twist the retaining ring 6 to rotate. The rotation of the retaining ring 6 drives the locking block 61 to rotate, so that the locking block 61 is locked into the arc groove. At this time, the retaining ring 6 no longer exerts a force on the limiting block 7. Using the elastic reset action of the spring 81, the limiting block 7 and the L rod 8 are reset. At this time, the limiting block 7 is fitted onto the locking block 61 through the limiting groove 71. Limited by the inner wall of the limiting groove 71, the cable cannot rotate, thus limiting and blocking the locking block 61, and completing the locking and fixing of the second retaining ring 6. At this time, the pay-off reel 41 is limited by the second retaining ring 6 and the first retaining ring 51, preventing the pay-off reel 41 from detaching from the mounting shaft 5. The first retaining ring 51 and the second retaining ring 6 are equally spaced on opposite sides, which reduces the friction between the pay-off reel 41 and the first retaining ring 51 and the second retaining ring 6 during rotation. When disassembling, press the pressing plate 82 to move the L rod 8. The movement of the L rod 8 drives the limiting block 7 to move, releasing the limitation on the locking block 61. The user reverses the second retaining ring 6, causing the locking block 61 to disengage from the arc groove and come to the sliding groove 52. Pulling the second retaining ring 6 outward can separate it from the mounting shaft 5, thereby releasing the limitation on the pay-off reel 41, and the pay-off reel 41 can be removed from the mounting shaft 5. Step 2: After the multiple pay-off reels 41 are installed, the copper wires of each pay-off reel 41 are sequentially twisted into the threading holes 32 on the reel 31. After the multiple copper wires converge, they pass through the guide ring 13, completing the threading preparation. After preparation, the drive device 11 and the drive device 2 on the bracket 14 for driving the take-up roller 15 are started. The drive device 2 drives the take-up roller 15 to rotate for take-up operation. The drive device 11 drives the turntable 4 to rotate. The rotation of the turntable 4 synchronously drives the twisting reel 31 to rotate through the connecting shaft 12, starting the cable twisting process. The drive device 11 starts and drives the turntable 4 and the twisting reel 31 to rotate at the same angular velocity. At this time, the multiple copper wires on the turntable 4 are intertwined with each other in a specific motion trajectory under the drive of the twisting reel 31. The guide ring 13 guides and constrains the copper wires, making the twisting process more stable and orderly, ensuring that the multiple copper wires can be twisted into a complete cable core according to the predetermined rules. After twisting, the cable is wound on the take-up roller 15.
