Description

TECHNICAL FIELD

[0001] The present application relates to the field of glass toughening furnace, and particularly relates to a uniform cooling device for glass toughening furnace. BACKGROUND

[0002] The glass toughening furnace is a core equipment for heating glass to a near softening state and then forming a compressive stress layer on the surface of the glass through rapid cooling, so as to improve the strength, impact resistance and thermal stability of the glass. In the glass toughening process, the cooling step is a key step for imparting excellent properties to the glass, and the cooling uniformity directly determines the quality of the toughened glass.

[0003] The existing glass toughening furnace cooling device adopts a structure design of a straight-line air duct cooperating with a fixed air nozzle. During cooling operation, the cooling air is transmitted through the straight-line air duct and blown out to the surface of the glass through the fixed air nozzle. However, for different sizes of glass, the air outlet direction and coverage range of the straight-line air duct are relatively fixed, which is difficult to adapt to the edges and corners of different sizes of glass, and the cooling air in these areas is easily insufficient. In addition, the angle and air volume adjustment capability of the fixed air nozzle are limited, and the glass size cannot be flexibly adjusted, which often causes uneven cooling of the glass in some positions. For example, the edge area of large-size glass is easily not fully covered by the cooling air, and the cooling speed is lower than that of the center area. Small-size glass may have a situation of excessive concentration of local cooling air due to the fixed position of the air nozzle. This uneven cooling problem will cause the stress distribution in the glass to be unbalanced, which not only reduces the quality of the toughened glass, but also may produce waste products, increasing production loss and cost.

[0004] In view of the above related technologies, the inventors believe that the cooling device with a fixed air duct has the defect of uneven overall cooling of the glass when blowing air to the glass, and therefore propose a uniform cooling device for glass toughening furnace to solve the above problems.
