The invention relates to a plate bending machine capable of automatically adjusting multiple groups of upper supporting roller devices, which belongs to the technical field of structures of super wide plate bending machines. Each group of upper supporting roller device is hung on the lower end of a beam through a spring, and the upper ends of the upper supporting roller devices are fixedly connected with fixed longitudinal lower inclined irons; the lower ends of both heads of the beam are respectively fixedly connected with oil tanks, telescopic links of the two oil tanks are coaxially opposite and parallel to upper rollers, a connection beam is connected between the two telescopic links of the two oil tanks, longitudinal upper inclined irons are uniformly distributed on the connection beam, and the lower surface of each longitudinal upper inclined iron is respectively contacted with the upper end surfaces of the corresponding fixed longitudinal lower inclined irons; the front side and the rear side of the lo
