Description

Technical Field

[0001] This utility model relates to the field of cable processing equipment technology, and specifically to a cable core unloading drum for cable core unloading operations. Background Technology

[0002] In the cable production and processing process, the cable core laying operation is one of the key processes. As the core component that carries the cable core roll and enables smooth laying, the rationality of the structure of the laying drum directly affects the laying efficiency, the quality of cable core laying, and the ease of operation.

[0003] Existing cable core feeding drums typically include basic structures such as a base and a chuck, enabling basic cable feeding functions. However, they still have many shortcomings in practical applications: Firstly, the inner ring support structure of existing wire feeding drums is mostly designed with fixed dimensions, which cannot be adapted to different inner diameter specifications of cable core rolls. As a result, a single wire feeding drum can only be adapted to a single specification of cable core roll, resulting in poor equipment versatility and increased equipment investment costs for manufacturing enterprises. Secondly, the rotating connection structure of some wire feeding drums is poorly designed, with a large gap between the base and the rotating disk. This can easily cause jamming during rotation, which not only affects the stability of the wire feeding speed, but may also cause the cable core to be stretched and deformed due to uneven force, thus affecting product quality. Third, most cable reels are not equipped with a dedicated handling and adaptation structure. The overall weight of the cable core roll after loading is large, and it is difficult to transfer it quickly by hand. Even with the help of tools, it requires a lot of manpower and resources, which reduces the efficiency of production flow. Summary of the Invention

[0004] In view of the technical problems existing in the background art, the present invention provides a cable core laying drum for cable core laying operations. Through optimized structural design, it facilitates cable core laying operations and effectively improves the adaptability of the device.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A cable core unloading drum includes a base, a rotating disk, and a chuck. The upper end face of the base is rotatably connected to the lower end face of the rotating disk, and the upper end face of the rotating disk is fixedly connected to the lower end face of the chuck. An outer ring stop bar is vertically arranged on the outer side of the chuck, and an inner ring support bar is symmetrically arranged in a ring at the axis of the chuck. One end of the inner ring support bar is perpendicular to the chuck and can move radially along the chuck. The cable core roll is placed on the chuck and fixed by the outer ring stop bar and the inner ring support bar.

[0006] In a preferred embodiment, the lower end face of the base is provided with a protruding strip to facilitate forklift loading and unloading.

[0007] In a preferred embodiment, an annular retaining rail is provided at the center of the upper end face of the base, and an annular groove is correspondingly provided on the lower end face of the rotating disk. A conveying roller is provided in the annular groove, and the annular retaining rail is engaged in the annular groove and rolls with the conveying roller.

[0008] In a preferred embodiment, connecting posts are symmetrically arranged in a ring on the outer side of the rotating disk. The two ends of the connecting posts are perpendicularly connected to the chuck and the rotating disk, respectively. The rotating disk and the chuck are coaxially arranged and rotate synchronously.

[0009] In the preferred embodiment, the inner ring support rod has an L-shaped structure, and the chuck has symmetrically arranged strip holes along the radial direction. One end of the inner ring support rod passes vertically through the strip hole, and the other end of the inner ring support rod is parallel to the bottom surface of the chuck. The inner ring support rod slides along the strip hole for limitation.

[0010] In a preferred embodiment, a locking seat is symmetrically arranged in a radial ring on the bottom surface of the chuck, and the inner ring support rod passes through the locking seat.

[0011] In the preferred embodiment, the end of the inner ring support rod is a threaded post, and the locking cap is threadedly engaged with the threaded post, together with the locking seat, locking the inner ring support rod in the slidable position.

[0012] A cable core unloading drum can achieve the following beneficial effects: 1. This application sets an inner ring support rod that can move radially on the chuck. With the limiting and guiding effect of the strip hole, the extension length of the inner ring support rod can be flexibly adjusted according to the cable core rolls with different inner diameter specifications. Then, the locking seat and locking cap are used to lock and fix it. This allows a single set of wire feeding drums to stably adapt to cable core rolls with multiple inner diameters. There is no need to equip wire feeding drums separately for different specifications, which greatly reduces the equipment investment cost of production enterprises and improves equipment utilization. 2. This application employs a combination structure of annular retaining rail, annular groove, and conveyor roller at the connection between the base and the rotating disk. The precise fit between the annular retaining rail and the annular groove reduces the clearance, and the conveyor roller converts sliding friction into rolling friction, significantly reducing rotational resistance and effectively preventing rotational jamming. Stable rotational performance ensures uniform wire feeding speed, prevents the cable core from being stretched and deformed due to uneven stress, and improves the quality of cable core feeding and the pass rate of subsequent processed products. 3. This application provides parallel protrusions on the lower end face of the base, which can be directly adapted to the fork forks of the fork, enabling the forklift to quickly pick up, put down and transfer the unloading drum after loading the cable core coil, eliminating the need for manual labor and saving manpower and material resources, shortening the turnover time, and is especially suitable for the high-efficiency operation needs in large-scale production scenarios. 4. This application establishes a rigid connection between the rotating disk and the chuck by symmetrically arranging connecting columns on the outer side of the rotating disk, ensuring that the two rotate coaxially and synchronously, thus avoiding structural deformation caused by uneven force. At the same time, the mating structure of each component has been optimized for limiting, reducing wear between components and extending the service life of the overall equipment.

[0014] In the figure: base 1, protrusion 101, annular rail 102, rotating disk 2, connecting column 201, annular groove 202, conveying roller 203, chuck 3, locking seat 301, strip hole 302, outer ring stop bar 4, inner ring support bar 5, threaded column 501, locking cap 502, cable core roll 6. Detailed Implementation

[0015] like Figure 1 As shown, the base 1, rotating disk 2, and chuck 3 of the cable core unloading drum achieve load-bearing and rotation functions through a reasonable structural cooperation. The base 1 and rotating disk 2 are rotatably connected, while the rotating disk 2 and chuck 3 are fixedly connected as one unit. Outer ring stops 4 are evenly arranged around the circumference of the chuck 3 to limit the radial displacement of the cable core roll 6; inner ring supports 5 are symmetrically arranged at its axis, and the inner ring supports 5 can move radially along the chuck 3. In use, the cable core roll 6 is placed on the chuck 3, and the outer ring stops 4 prevent the cable core roll 6 from sliding outward. At the same time, the extension length of the inner ring supports 5 is adjusted to ensure a tight fit with the inner ring of the cable core roll 6. Finally, through the synergistic action of the outer ring stops 4 and the inner ring supports 5, the cable core roll 6 is stably limited, preventing shaking and tangling during the unloading process.

[0016] Preferred solutions include Figure 2As shown, a protrusion 101 is provided parallel to the lower end face of the base 1, and the structure of the protrusion 101 is adapted to the forklift fork teeth. When it is necessary to transfer the wire reel, the forklift fork teeth can be directly inserted into the gap between the protrusions 101 without the need for additional auxiliary tools, so as to complete the picking, placing and transferring of the wire reel, effectively replacing manual handling, reducing labor consumption and improving turnover efficiency.

[0017] Preferred solutions include Figure 2 and Figure 3 As shown, an annular retaining rail 102 is provided at the center of the upper end face of the base 1, and an annular groove 202 is correspondingly provided on the lower end face of the rotating disk 2. A conveying roller 203 is installed in the annular groove 202. During assembly, the annular retaining rail 102 is engaged into the annular groove 202, and the two are precisely matched to reduce the gap; the conveying roller 203 makes rolling contact with the annular retaining rail 102, converting the sliding friction between the base 1 and the rotating disk 2 into rolling friction. This structural design can significantly reduce rotational resistance, avoid jamming during rotation, ensure uniform rotational speed during cable feeding, and prevent the cable core from being stretched and deformed due to uneven force.

[0018] Preferred solutions include Figure 2 and Figure 3 As shown, symmetrical connecting posts 201 are arranged on the outer side of the rotating disk 2. The two ends of the connecting posts 201 are fixedly connected to the chuck 3 and the rotating disk 2 respectively, forming a rigid support structure. This design ensures that the rotating disk 2 and the chuck 3 are coaxially arranged and rotate synchronously, avoiding uneven force due to structural misalignment, and thus preventing eccentric swaying of the cable core roll 6 during the unwinding process.

[0019] Preferred solutions include Figure 4 As shown, the inner ring support rod 5 has an L-shaped structure, and the chuck 3 has radially symmetrically arranged strip-shaped holes 302. The vertical section of the inner ring support rod 5 passes through the strip-shaped holes 302, while the horizontal section is parallel to the bottom surface of the chuck 3. During adjustment, the inner ring support rod 5 can slide radially along the guide direction of the strip-shaped holes 302. By changing the extension length of the vertical section, it can adapt to cable core rolls 6 with different inner diameter specifications, thus improving the versatility of the pay-off drum.

[0020] Preferred solutions include Figure 5 and Figure 6 As shown, locking seats 301 are symmetrically arranged radially on the bottom surface of the chuck 3, and the horizontal section of the inner ring support rod 5 passes through the locking seats 301. The locking seats 301 provide a sliding channel for the inner ring support rod 5 to ensure its adjustment flexibility, and also limit the horizontal section to prevent the inner ring support rod 5 from sliding or radially offset during the line laying process, thus ensuring the stability of the support.

[0021] Preferred solutions include Figure 6As shown, the end of the horizontal section of the inner ring support rod 5 is provided with a threaded post 501, and the locking cap 502 is threadedly engaged with the threaded post 501. After the inner ring support rod 5 is adjusted to the target position, the locking cap 502 is tightened to make it fit tightly against the side of the locking seat 301. The two together form a clamping force to fix the inner ring support rod 5 in the current position, preventing the support rod from shifting during the cable laying process and ensuring stable support for the cable core roll 6.

[0022] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
