The invention discloses a circle curling machine capable of achieving automatic discharging. The circle curling machine is characterized in that the circle curling machine comprises a base plate; a set of first supporting rods and a set of second supporting rods are arranged at the upper side of the base plate; the first supporting rods are connected with a first vertical plate, and the second supporting rods are connected with a second vertical plate; a circle curling device is connected between the first vertical plate and the second vertical plate in a rotating mode; a power device is arranged at one side of the second vertical plate; a through hole is formed in one side of the second vertical plate, and an automatic discharging device is connected into the through hole; fixed rollers are arranged between the first vertical plate and the second vertical plate; kidney-shaped through holes are symmetrically formed in one side of the first vertical plate and one side of the second vertical plate and are further located below the fixed rollers; and movable rollers are connected into the corresponding kidney-shaped through holes, and gap adjusting devices are arranged at the two ends of the movable rollers. The circle curling machine capable of achieving automatic discharging has the advantages that scale marks can be increased through a hydraulic machine, the gap height of flattening equipment can be adjusted more accurately, an induction device is adopted for automatic discharging, and materials enter guide rails and then enter into the next mechanism automatically; and the circle curling machine is simple in structure, easy and safe to operate and suitable for automatic production.
