Duckbilled balanced adjustable film blowing air ring auxiliary device

The utility model relates to a duckbilled balanced adjustable film blowing air ring auxiliary device which comprises two groups of air blowing cooling mechanisms arranged on the outer side of a film above an air ring, and the two groups of air blowing cooling mechanisms respectively blow to two white film areas of the film; the air blowing cooling mechanism comprises a duckbilled air blowing head, the interior of the duckbilled air blowing head is hollow and is an air cavity, and an air baffle used for slowing down the air outlet speed is installed in the air cavity. An air inlet is formed in one end of the duckbilled blowing head, an air outlet is formed in the other end of the duckbilled blowing head, the air outlet is of an arc-shaped structure, and the radian of the air outlet is matched with that of a film. The blowing cooling mechanism is used for independently blowing and cooling the white film area, so that the cooling speed of the white film area is increased, the cooling speed of the black film area
