Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of uncoilers, in particular to an external frame for uncoilers. Background Art
[0002] In the field of steel strip processing, an uncoiler is required to unwind the rolled steel coil to form a strip-shaped steel strip for easy processing. In order to prevent the steel coil from shifting during the unwinding process, the uncoiler needs to press the pressure roller of the pressure-feeding structure against the unwinding part of the steel coil. At present, the pressure-feeding structure is usually directly installed on the top of the uncoiler body in a swingable manner, but the space available for the pressure-feeding structure to be installed on the top of the uncoiler body is limited, so that the pressure roller of the pressure-feeding structure can only rotate with the unwinding of the steel coil and press against the unwinding part of the steel coil. The pressure-feeding structure installed on the top of the uncoiler body does not have a component that can drive the pressure roller to rotate, and cannot assist the unwinding of the steel coil. It can only prevent the steel coil from shifting during the unwinding process, and its function is relatively simple. Utility Model Content
