Patent Description:
Glass has excellent transmittance and scratch resistance, so it is widely used in daily life. At present, related glass products can be seen not only in buildings and general daily necessities, but also in electronic appliances and vehicles. Peripheral products have flooded people's lives.

Most of the glass is made by batching, melting, forming, annealing and other processes. After the glass is made, further processing operations can be performed to improve the functionality of the glass. For example, the annealed glass can be cut to the required size, then the glass is heated by a glass heating furnace to soften the glass, and then the glass is rapidly cooled through a cooling device to cool the glass surface below the annealing temperature for rapid hardening and shrinking. When interior of the glass shrinks, it will cause a compressive stress on the surface, and the interior of the glass will produce a tensile stress, which can increase the strength of the glass to form a so-called strengthened glass.

In the above descriptions, the cooling device at least comprises wind outlet structures laterally arranged above and below. There are several rollers disposed between the above and below wind outlet structures. The rollers can carry glass, and then use the wind outlet structure to output wind and blow it toward the glass, so as to achieve the purpose of rapid cooling of the glass.

However, because the size of the glass to be cooled each time is different, when the cooling device of the prior art is activated, all the wind outlet holes of the wind outlet structure can only output wind power at the same time, and cannot control the appropriate number of wind outlet holes for wind supply operation according to the size of the glass, which consumes energy and generates unnecessary costs.
