The invention relates to a strip steel cold bending forming machining manufacturing technology, in particular to a vertical active uncoiling device for spiral steel plate bin forming. The device comprises a bracket, a rotating device, a vertical guide roller device, a circumference fixing device and a steel coil driving device, the inner wall of the rotating device is provided with a universal ball, the steel coil driving device is provided with two driving wheels driven by a positive displacement straight gear, power is provided by a servo motor, and the gap between the two driving wheels isadjusted by moving the driving wheels through a manual linear module and a linear guide rail. A steel coil for manufacturing a spiral steel plate bin is placed on the rotating device, a steel plate isdriven to advance through the steel coil driving device, whether the steel plate exists within a calibrated distance or not is judged according to a photoelectric sensor, an analog output signal is sent to a servo motor control system, the speed difference between the driving speed and the forming speed of the steel plate is controlled, and steel plates with different thicknesses of 3mm-5mm can be machined and manufactured. The device better protects the outer surface of the steel plate, reduces the load of a motor of a steel plate forming unit, and improves the working efficiency.
