Tempered glass cooling device

The invention relates to the technical field of glass cooling, in particular to a tempered glass cooling device. The tempered glass cooling device convenient to adjust is provided. A tempered glass cooling device comprises a long mounting plate, a conveying component, a glass width detection component, an exhaust component and the like. The long mounting plate is provided with a conveying part, the conveying part is provided with a glass width detection part and an exhaust part, the glass width detection part is connected with the exhaust part, the long mounting plate is provided with a driving speed adjusting part, and the driving speed adjusting part is connected with the conveying part. When wide glass is cooled, the limiting frame does not block the area of the air guide holes in the square frame to be enlarged, so that the wide glass can be comprehensively cooled, when narrow glass is cooled, the narrow glass makes contact with the bevel driven plate, the limiting frame does not block the area of the air
