Steel plate rolling machine

The utility model relates to a steel plate veneer reeling machine which comprises a supporting frame, two lower winding rollers which are arranged at the same height and are parallel to each other are rotationally connected to the supporting frame in the horizontal direction, and an upper winding roller parallel to the lower winding rollers is rotationally connected between the lower winding rollers, and is characterized in that one end of the supporting frame is rotationally connected with a rotating block, and a first sliding block is arranged in the rotating block; when the rotating block is arranged in the vertical direction, one end of the upper winding roller is arranged in the first sliding block to rotate, the supporting frame is rotationally connected with an inclined air cylinder inclining upwards, and an output shaft of the inclined air cylinder is connected with the rotating block. The blanking device has the effect that the blanking operation of the plate rolling machine is simpler and more conve
