Therefore, the air pressure of the cooling air needs to be adjusted according to the thickness of the glass, and the quality accident is avoided. When processing the glass of different thickness, through first lifting unit 34 is adjusted go up the air grid 31 with down the air grid 32 with the distance of rollgang 5 is adjusted go up the air grid 31 with down the air grid 32 and wait to process the distance between the glass, reach the regulation go up the air grid 31 with down the air grid 32 blows the purpose of the wind pressure of the cooling air on waiting to process the glass surface, makes the wind pressure be fit for the glass that will process to improve finished glass's quality. When glass with smaller thickness is processed, the distance between the upper air grid 31 and the lower air grid 32 and the conveying roller way 5 is shortened, so that the air pressure can be improved, and the cooling speed is accelerated; when processing the great glass of thickness, increase go up the air grid 31 with the distance between air grid 32 and the rollgang 5 down, just can reduce the wind pressure, avoid cooling's speed too fast, lead to glass to explode and split.
