Detailed Implementation
[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0022] Please see Figures 1 to 8This utility model provides a steel coil unwinding device, including two tensioning assemblies, a support tube 1, and a bracket 2. Each tensioning assembly includes multiple tensioning elements, a fixed ring 3, and a movable ring 4. Each tensioning element includes a support plate 5, a first tensioning rod 6, and a second tensioning rod 7. The support tube 1 has multiple adjusting grooves 8 in its middle. A rotating rod 9 is rotatably mounted inside the support tube 1, and the rotating rod 9 is driven by a motor 10. The rotating rod 9 has a bidirectional thread 11 in its middle, and two threaded sleeves 12 are fitted onto the bidirectional thread 11. The outer side of each threaded sleeve 12 is provided with… The support tube 1 has multiple pushing blocks 13, each extending out of the adjusting groove 8. Bearings 14 are provided at both ends of the support tube 1. Two lifting assemblies are provided on the bracket 2. A first tensioning rod 6 is hinged to the fixed ring 3 and located on the fixed ring 3. A second tensioning rod 7 is hinged to the moving ring 4 and located on the moving ring 4. The first tensioning rod 6 and the second tensioning rod 7 are respectively hinged to the supporting plate 5 and located below the supporting plate 5. The fixed ring 3 is fixedly connected to the support tube 1 and sleeved on the support tube 1. At one end of the support tube 1, the movable ring 4 is slidably connected to the support tube 1 and sleeved in the middle of the support tube 1. Multiple pushing blocks 13 are respectively fixedly connected to the movable ring 4 and located at one end of the movable ring 4. The support tube 1 is mounted on two lifting assemblies via the bearing 14. Through the design of multiple tensioning elements, the fixed ring 3, and the movable ring 4, uniform tensioning of the steel coil 22 can be achieved. In particular, the first tensioning rod 6 and the second tensioning rod 7, along with the supporting plate 5, the fixed ring 3, and the movable ring 4, are effectively connected. The hinged design of ring 4 allows for more flexible adjustment of tension to accommodate steel coils 22 of different diameters and weights. The support tube 1 has multiple adjustment grooves 8 in the middle. The rotating rod 9 is driven by the motor 10 and has a bidirectional thread 11. This design allows the rotation of the rotating rod 9 to move the two threaded sleeves 12 and the pushing block 13 on their outer sides, thereby pushing the moving ring 4 to slide along the support tube 1, achieving further adjustment of tension. This mechanical adjustment method is simple, reliable, and easy to maintain.
[0023] The two tensioning components are symmetrically arranged on the support tube 1, and the multiple tensioning elements are arranged in a cross-shaped symmetrical arrangement between the fixed and buffering moving ring 4. This symmetrical design not only improves the stability of the equipment, but also ensures that the steel coil 22 is subjected to uniform force during the unwinding process, avoiding deformation or damage to the steel coil 22 due to uneven force.
[0024] Secondly, the inner side of the moving ring 4 is provided with multiple limiting blocks 15, and the middle part of the support tube 1 is also provided with multiple limiting grooves 16, and each limiting groove 16 is located between two corresponding adjusting grooves 8. The multiple limiting blocks 15 are slidably connected to the support tube 1 and are located in the corresponding limiting grooves 16. By the slidable connection between the limiting blocks 15 provided on the inner side of the moving ring 4 and the limiting grooves 16 in the middle part of the support tube 1, this design not only limits the movement range of the moving ring 4, but also ensures the stability of the moving ring 4 during the movement process, and prevents equipment damage or safety hazards caused by excessive movement.
[0025] Furthermore, a buffer pad 17 is provided on the outer side of the support plate 5. The outer side of the buffer pad 17 has an arc-shaped surface 18. Through the buffer pad 17, not only can the friction between the support plate 5 and the steel coil 22 be reduced, but it can also better adapt to the curvature of the surface of the steel coil 22, thereby improving the durability and service life of the equipment.
[0026] Additionally, the supporting assembly includes a cover seat 19 and a fixing seat 20. A cavity 21 for accommodating the bearing 14 is provided between the cover seat 19 and the fixing seat 20. The cover seat 19 is hinged to the fixing seat 20 and covers the top of the fixing seat 20. The other end of the cover seat 19 and the fixing seat 20 are fixedly connected by bolts. The support tube 1 is disposed within the cavity 21 via the bearing 14, and the bearing 14 abuts against the cover seat 19 and the fixing seat 20. The fixed seat 20 is fixedly connected to the bracket 2 and located on the bracket 2. In this design, the cover seat 19 and the fixed seat 20 are fixedly connected by hinge and bolts, forming a cavity 21 that can accommodate the bearing 14. This not only simplifies the installation and maintenance process of the equipment, but also ensures that the support tube 1 is stably set in the cavity 21 through the bearing 14, thereby improving the overall stability and safety of the equipment. At the same time, the fixed connection between the fixed seat 20 and the bracket 2 also ensures the stability of the entire unwinding equipment.
[0027] When using this invention, the steel coil 22 is placed on the support tube 1, ensuring its center is aligned with the center of the support tube 1. The positions and states of the two tensioning components are observed, ensuring they are symmetrically arranged on the inner surface of the support tube 1. Based on the diameter and weight of the steel coil 22, the motor 10 is started, causing the motor 10 to drive the rotating rod 9 to rotate clockwise. The two threaded sleeves 12 move away from each other, while the moving ring 4 is pushed by the pushing block 13, thereby adjusting the tension between the first tensioning rod 6 and the second tensioning rod 7 and the supporting plate 5. The hinge angle is adjusted so that the tension of the support plate 5 is gradually increased, and the deformation of the steel coil 22 is observed to ensure that it is in a stable tension state. When the steel coil 22 is firmly fixed, the motor 10 can be stopped. Then, the bearing 14 end of the support tube 1 is placed on the fixed seat of the two lifting components. Finally, the cover seat 19 is covered and the final fixation is completed by bolts. This method solves the technical problem that the steel coil 22 may shift during rotation due to the different widths of different models, which may affect the operation of subsequent continuous operation units.

Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
