The invention relates to the technical field of blow molding machines, in particular to a three-in-one automatic air ring structure and guide assembly of a film blowing machine, which comprises an upper air plate mounted on the side wall, close to the top end of an air outlet, of an annular groove, a lower air plate slidably mounted on the side wall, close to the bottom end of the air outlet, of the annular groove, and a second guide plate obliquely mounted on the side, close to the air outlet, of the upper air plate. A first guide ring is vertically arranged on the top wall of the first guide plate; the lower air plate moves downwards; and when the lower air plate moves downwards, the temperature control assembly increases the temperature of the heater. According to the scheme, the guiding assembly used for guiding the air direction is arranged at the air outlet, the final air speed and the final air volume of the air outlet are changed by adjusting the positions of the upper air plate and the lower air plat
