Description

Technical Field

[0001] This utility model belongs to the technical field of tensioning devices, and in particular relates to a tensioning device for a steel strip feeding rack. Background Technology

[0002] The steel strip feeding rack tensioning device is a key piece of equipment used to stabilize and fix metal coils, such as steel strips and color steel coils, ensuring that they rotate smoothly without deviation during the uncoiling process. Its core function is to reliably tighten the inner diameter of the coil through a mechanical structure. However, when tightening the steel strip, manual tightening is required, and automatic tensioning cannot be performed according to different sizes, which reduces the working efficiency of the device. Therefore, a steel strip feeding rack tensioning device is proposed.

[0003] For example, Chinese patent CN210763355U discloses a tensioning device for a steel strip feeding rack, including a base plate, a rotating shaft, and a support rod. A support column is welded to the upper side of the base plate, and a mounting seat is installed at the upper end of the support column. Bearings are installed at both ends of the rotating shaft. The rotating shaft has two sections of threads in opposite directions. A collar is screwed onto the rotating shaft. A first lug is welded to the outer side of the collar. A connecting rod is hinged to the first lug via a pin. A second lug is welded to the lower side of the support rod. The upper end of the connecting rod is hinged to the second lug. Radial sleeves are welded to all four sides of the rotating shaft. An insertion rod is welded to the lower side of the support rod, and the insertion rod is inserted into the sleeve.

[0004] The existing technical documents have the following problems:

[0005] Existing technical documents have some drawbacks in use, such as the need for manual tensioning of the steel strip, the inability to automatically tension it according to different dimensions, which reduces the efficiency of the device. Furthermore, the height and angle of the steel strip cannot be adjusted during tensioning and feeding, thus reducing the flexibility of the device after installation. Therefore, we propose a steel strip feeding rack tensioning device. Utility Model Content

[0006] The purpose of this utility model is to address the aforementioned technical problems by providing a steel strip feeding rack tensioning device, which facilitates automatic tensioning of different steel strips and allows for adjustment of the height and angle of the steel strip feeding after tensioning.
