However, during the use of this steel strip unwinding equipment, the center of the circle is not easy to find, eccentric rotation is prone to occur, and the stability is poor. At the same time, the position of the positioning roller is also fixed. As the unwinding amount increases, the diameter of the steel strip gradually decreases, which increases the position difference between the positioning roller and the steel strip, and reduces the stability.
