Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of uncoilers, in particular to an improved uncoiler pressure-feeding structure. Background Art
[0002] In the field of steel strip processing, an unwinder 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 deflecting during the unwinding process, the unwinder needs to be pressed against the unwinding part of the steel coil through a pressure-feeding structure, and then the pressure roller of the pressure-feeding structure rotates to drive the steel coil to unwind into a steel strip. At present, the pressure roller is rotatably arranged on the swing arm of the pressure-feeding structure through the roller shaft heads at both ends of its roller body, and the roller shaft head at one end is passed out of the swing arm, and then connected to the roller drive module of the pressure-feeding structure by a chain drive module. The pressure roller installed with this structure can be used stably in a short period of time, but after long-term use, because only the roller shaft head at one end of the pressure roller is connected to the roller drive module by a chain drive module, the pressure roller always has a certain degree of imbalance, and under long-term imbalance, the roller shaft head connected to the roller drive module by the chain drive module is greatly worn, and it is easy to be broken by force when the pressure roller is pressed against the unwinding part of the steel coil, affecting the durability of the pressure roller.
