Abstract
This invention provides an uncoiling and rewinding device, including a rocker arm and an uncoiling knife for opening a steel coil. The uncoiling and rewinding device also includes a pinch roller that presses against the steel coil during uncoiling to facilitate uncoiling by the uncoiling knife, presses against the steel coil during rewinding to facilitate rewinding by the ground roller, and cooperates with a guide roller to pinch and feed the strip steel. The uncoiling and rewinding device also includes a rewinding roller that presses against the guide roller to make the steel coil strip head curl upward so that the steel coil strip head passes through the guide plate assembly. A rotatable swing frame is mounted on the rocker arm, and the uncoiling knife, pinch roller, and rewinding roller are all mounted on the swing frame. The uncoiling and rewinding device also includes a first driving device for driving the rocker arm to swing between the steel coil and the guide roller, and a second driving device for driving the swing frame to rotate.
