Description

Technical Field

[0002] Uncoiling of steel coils refers to the process of lifting the stainless steel coils by hoisting or forklift and placing them on a bracket, and then uncoiling them using a drive device. During uncoiling, it is necessary to protect the steel coils from exploding and causing injuries.

[0003] For example, a Chinese utility model with announcement number CN213530229U discloses a "protective uncoiler for strip steel coils". When the device is used, the steel coil is wound on the four coil plates of the uncoiling mechanism, and the outer periphery of the steel coil is clamped along the side by the limiting block by pulling the second rod barrel of the limiting mechanism. As the thickness of the steel coil decreases, the spring rod pulls the second rod barrel through tension, and the steel coil is clamped as the thickness decreases. The steel coil is not easy to fall off, and the extension shaft of the uncoiling mechanism is flatly supported and stabilized by the support plate of the second connecting rod, and is not easy to tilt. The surface of the steel coil is supported by the limiting wheel of the first connecting rod. When unloading, the steel coil unfolds less. The overall structure is reasonable, no human control is required, it is easy to use, highly practical, and has an improved safety factor.
