[0002] In the industrial production process, unwinding devices are often needed to unwind coils. In these unwinding devices, especially for unwinding heavy coils, if the support is not good, firstly, it is easy to shake during unwinding, which affects the production accuracy and quality of the subsequent stage. Secondly, when unwinding at high speed, the coil itself is easy to fall off the rack, resulting in the loss of raw materials and affecting the production quality. For this reason, we hope to find an unwinding device that can maintain stability and safety when unwinding heavier coils. Utility Model Content
