Description

Technical Field

[0001] This invention relates to the field of wire and cable manufacturing technology, and in particular to a stranding device for producing wires and cables. Background Technology

[0002] Chinese patent document CN219225969U discloses a stranding device for producing wires and cables, relating to the field of stranding device structure. The device includes a main body with a rotating disk and a winding disk mounted on it. A stranding spool is rotatably mounted on the top side of the main body, located between the rotating disk and the winding disk, via a support plate. An external gear ring is coaxially mounted on one side of the stranding spool. A motor is mounted on the top side of the main body. Multiple mounting holes are evenly distributed along the circumference on one side of the stranding spool. A fixing frame is installed in each of the mounting holes. Two I-shaped wheels are rotatably mounted on the inner wall of the fixing frame via a rotating shaft. Through the arrangement of the two I-shaped wheels, the cable passes through the circular channel formed by the two I-shaped wheels. During the stranding process, rolling friction occurs between the cable and the two I-shaped wheels, thereby reducing damage to the insulation layer and facilitating the production and use of wires and cables.

[0003] However, the above-mentioned equipment has significant defects in the initial winding of cables: it lacks an effective fixing structure for the cable end, and cannot be directly and reliably connected to the winding reel and rotate and wind synchronously with it. During operation, the cable end must be manually wound around the winding reel at least once in advance, and the beginning end can only be barely fixed by subsequent pressing. This process is not only cumbersome to operate, but also time-consuming and labor-intensive, which significantly reduces the winding efficiency and the convenience of operation. Therefore, we propose a stranding equipment for producing wires and cables. Summary of the Invention

This fixing connection method is simple and efficient, ensuring stable subsequent winding and eliminating concerns about detachment. It solves the problem of some existing equipment lacking an effective fixing structure for the cable end, making it impossible to directly and reliably connect to the take-up reel and rotate synchronously with it. During operation, the wire end must be manually wound around the take-up reel at least one turn beforehand, and the beginning end can only be barely fixed by subsequent wire pressing. This process is not only cumbersome but also time-consuming and labor-intensive, significantly reducing winding efficiency and ease of operation, thus improving the practicality of the equipment.

[0016] This wire and cable stranding equipment, through the coordinated use of a drive mechanism and a snap-fit ​​mechanism, allows for quick replacement of the take-up reel and the winding reel. This facilitates the direct replacement of a fully loaded winding reel when the metal wire on the winding reel is used up, and the direct replacement of an empty winding reel when the cable on the take-up reel is fully wound. This achieves seamless connection, high-efficiency operation, and ensures the effectiveness of the equipment, which is conducive to its promotion and use.

[0017] This wire and cable stranding equipment, through the combined use of a resistance-increasing mechanism and a winding reel, increases the rotational resistance of the winding reel by having the contact plate closely adhere to it during the stranding process. The metal wire on the winding reel can be tightened and straightened during unwinding, ensuring the stranding effect. At the same time, the rollers and connecting rods help to improve the stability of the rotating disc as it rotates with the stranding reel. Attached Figure Description

One end of the threaded rod 42 is rotatably installed on the wire pressing plate 43. Through the cooperation of the wire pressing mechanism 4 and the take-up reel 9, the end of the twisted cable can be directly pressed and fixed by the wire pressing plate 43 during the initial winding of the cable. This fixing connection method is simple and efficient, ensuring the stability of subsequent winding and eliminating concerns about falling off. It solves the problem that some existing equipment lacks an effective fixing structure for the cable end, making it impossible to directly and reliably connect to the take-up reel and rotate and wind synchronously with it. During operation, the cable end must be manually wound around the take-up reel at least one turn in advance, and the beginning end can only be barely fixed by subsequent wire pressing. This process is not only cumbersome but also time-consuming and labor-intensive, significantly reducing the winding efficiency and ease of operation, thus improving the practicality of the equipment.

One end of each set of rectangular blocks 55 is fixedly connected to the inner wall of the corresponding storage slot 54. The top of each set of rotating blocks 52 is provided with a through slot 57 that communicates with the corresponding storage slot 54.

Through the cooperation of the drive mechanism 5 and the snap-fit ​​mechanism 6, the take-up reel 9 and the winding reel 12 can be quickly replaced. This makes it convenient to directly replace the fully loaded winding reel 12 after the metal wire on the winding reel 12 is used up, and to directly replace the empty winding reel 9 after the cable on the winding reel 9 is fully wound. This achieves seamless connection, efficient operation, and ensures the effectiveness of the equipment, which is conducive to the promotion and use of the equipment.

[0024] The resistance-increasing mechanism 7 includes a movable rod 71, a contact piece 72, a connecting piece 73, and a third spring 74.

The mounting groove 83 is formed through the column 81, and the second motor 84 is fixedly mounted on the top inner side of the mounting groove 83.

Each of the four sets of wire guide grooves 85 has two sets of wire clamping wheels 86 rotatably installed. The two sets of wire clamping wheels 86 in each set of wire guide grooves 85 form a pair. Each pair of wire clamping wheels 86 forms a set of wire passing holes. The rotating disk 10 is sleeved on the column 81. The outer surface of the column 81 is fixedly installed with a limit ring 16.

[0026] Working principle: Initially, each reel 12 is fully wound with metal wire. The wires are pulled out and passed through the threading holes formed between each pair of wire-clamping wheels 86. They are manually and simply twisted together to form the cable end. The end is then pulled to the pressure plate 43 on the take-up reel 9. Tightening the threaded rod 42 on the fixing block 41 moves the pressure plate 43, firmly pressing the cable end onto the take-up reel 9 for fixation. Next, stranding begins. The second motor 84 and the first motor 51 are started. The second motor 84 drives the stranding reel 82 to rotate, stranding the metal wires together to form the cable. Simultaneously, the first motor 51 drives the corresponding rotating block 52 to rotate. This rotating block 52, through its rectangular block 55, cooperates with... Another set of rotating blocks 52 has rectangular blocks 55 that drive the take-up reel 9 to rotate. The take-up reel 9 continuously winds and winds the twisted cable. After the cable on the take-up reel 9 is fully wound, the two sets of levers 58 are moved to drive the two sets of rectangular blocks 55 into the respective storage slots 54 and compress the respective first springs 56. After the two sets of rectangular blocks 55 are disengaged from the docking slots 53 on both sides of the take-up reel 9, the take-up reel 9 can be removed and replaced with a new empty take-up reel 9. After the metal wire on each reel 12 is used up, the fixing plate 63 is pressed down and the second spring 64 is compressed, which drives the locking rod 62 to retract into the fixing sleeve 61. The locking rod 62 disengages from the through rod 13, and the through rod 13 can be pulled out to remove the reel 12 and replace it with a new full reel 12.
