In order to improve the processing efficiency, a reeling conveyor rack is generally provided to allow the metal strips to automatically enter the punch press to be punched to form workpieces. In the related art, the coils of the metal strips are mounted on a rotating shaft, and the rotating shaft rotates to realize the unwinding and conveying of the metal strips. However, due to the narrow width of the metal strips, as the rotating shaft unwinds, the moving direction of the metal strips is easily offset, and the metal strips cannot smoothly enter the punch press processing position, requiring manual adjustment, resulting in low processing efficiency and not conducive to production.
