Description

Technical Field

[0001] This utility model relates to the field of winding machine equipment technology, and in particular to a steel strip winding machine that reduces wear. Background Technology

[0002] In the production and processing of steel strip, the coiling process is one of the crucial steps in forming the final product. After continuous cold rolling, annealing, or coating processes, the steel strip is typically wound into coils by a coiling machine for easy transport and storage. Traditional steel strip coiling equipment generally uses fixed tension or passive coiling methods. In actual operation, factors such as steel strip thickness, speed, or material fluctuations can cause tension instability, leading to problems such as wrinkling, uneven coiling, or slippage during the coiling process. This, in turn, exacerbates the relative friction and wear between the steel strip and the coiling components.

[0003] In existing technologies, most steel strip winding machines only have single-point drive or simple damping structures, making it difficult to achieve dynamic tension adjustment throughout the winding process. During high-speed operation or conversion between multiple steel strip specifications, traditional structures are unable to adapt to constantly changing process conditions, easily causing local over-tensioning or under-tensioning, which affects the appearance quality of the product and shortens the service life of the equipment. In particular, the wear of the winding rollers, guide rollers, and other parts in contact with the steel strip is especially severe.

[0004] Some devices attempt to compensate for tension by adding torque motors or brakes to the winding spindle, but these often result in low control accuracy or delayed feedback response, making it difficult to achieve continuous and stable tension control. The lack of real-time feedback and automatic adjustment mechanisms is also a common problem in current winding equipment, which is particularly evident under long-term operation or high-precision winding requirements.

[0005] In view of this, the inventors specifically designed a steel strip winding machine that reduces wear, and this invention arises from this. Utility Model Content

[0018] (III) Beneficial Effects

[0038] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0039] like Figure 1 and Figure 2 As shown, the present invention provides a steel strip winding machine for reducing wear, mainly comprising a frame 1, a rotating shaft assembly 2, a tray 3, a drive mechanism 4, and a tension adjustment device 5. The frame 1, as the overall load-bearing structure, is used to install and support the other components, and is typically a steel structure or a welded frame made of aluminum profiles.

[0040] like Figure 1 and Figure 3 As shown, the rotating shaft assembly 2 is mounted on the frame 1 and is a key structure for achieving steel strip winding. It includes a hollow main shaft 21, with both ends of the main shaft 21 connected to the frame 1 via bearings, enabling it to rotate smoothly. To further improve rotational accuracy and structural stability, a reinforcing shaft core or a pitch adjustment assembly 22 can be inserted inside the main shaft 21. The pitch adjustment assembly 22 includes a fixed plate 221, a pitch adjustment plate 222, and a connecting rod 223. The pitch adjustment plate 222 is rotatably connected to the fixed plate 221 via the connecting rod 223, allowing for appropriate adjustment of the winding center height when winding steel strips of different thicknesses or widths, thereby improving the uniformity of the steel strip and its winding adaptability.

[0041] The tray 3 is fixedly mounted on the rotating shaft assembly 2. Its structure is disc-shaped or multi-claw structure, and it can be replaced with various specifications according to the diameter of the steel coil. In order to facilitate the removal of steel strip debris generated during the operation, several through openings 31 can be provided on the tray 3 to prevent debris from accumulating and causing scratches or jamming.

[0042] like Figure 3 As shown, the drive mechanism 4 is housed within the frame 1, and the preferred drive method is a combination of motor 41, reducer 42, and sprocket 43. The output shaft of motor 41 is connected to sprocket 43, and through a chain drive structure, it is connected to the input end of reducer 42, thereby driving reducer 42 to evenly output power to main shaft 21, causing the rotating shaft assembly 2 to drive tray 3 to rotate slowly and stably, achieving smooth winding of the steel belt. To avoid slippage or vibration during transmission, sprocket 43 can be equipped with a tensioning wheel assembly to ensure the tension of the chain during operation.

[0043] like Figure 2 and Figure 6 As shown, the core improved structure is the tension adjustment device 5, which is located between the drive mechanism 4 and the rotating shaft assembly 2. It is an important means for this invention to reduce wear. This device includes several adjusting plates 51, a first pressure roller 52, a second pressure roller 53, and a clamping plate 54. The first pressure roller 52 is fixedly arranged between the adjusting plates 51 and remains stationary, serving as a support surface for the steel strip. The clamping plate 54 is located outside the adjusting plates 51 and has a waist-shaped hole 55 along its length. The second pressure roller 53 is located on the waist-shaped hole 55 and can slide along the hole to adjust the tension or relaxation of the steel strip. One end of the second pressure roller 53 is equipped with a locking shaft 56. By rotating or snapping, the second pressure roller 53 can be secured in any position within the waist-shaped hole 55, thus meeting the clamping requirements of steel strips with different thicknesses and stiffnesses.

[0044] like Figure 4 As shown, to further improve the accuracy and convenience of adjustment, a rack 61 can be installed on one side of the oblong hole 55, and a gear 62 meshing with it is provided at one end of the second pressure roller 53. By rotating the gear 62, the second pressure roller 53 can achieve precise linear movement within the oblong hole 55. This structure is more controllable and convenient than the traditional bolt adjustment method, which is conducive to improving on-site operation efficiency.

[0045] like Figure 5 As shown, to make the angle of the tension adjustment device 5 adjustable, the adjustment plate 51 can also be provided with a crescent-shaped groove 71 and equipped with a locking rotating head 72. When the angle of the steel strip entering the coil deviates or different working conditions require different angle guide paths, the locking rotating head 72 can be loosened to make a slight angle swing of the entire pressure roller assembly, and then locked again to ensure that the steel strip is always in the optimal angle and tension state before entering the winding area.

[0046] like Figure 6 As shown, an elastic coating layer 8, such as rubber, polyurethane, or silicone, can be further provided on the surface of the second pressure roller 53 to improve the adhesion to the steel strip, prevent slippage, absorb some vibration impact, and further reduce micro-wear on the steel strip surface. This elastic coating structure can also maintain guiding accuracy and stability when there are small particles or oil stains on the steel strip surface.

[0047] Through the above-mentioned structural combination, this utility model introduces an adjustable tension control structure and an angle guiding structure on the basis of the traditional steel strip winding structure. It can realize dynamic tension adjustment and clamping angle optimization of the steel strip during the winding process, ensuring that the steel strip can still maintain stable and accurate winding at high speed, and significantly reducing problems such as roller wear and steel strip abrasion caused by uneven tension or slippage.

[0048] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
