Background

In the production process of toughened glass, stress spots (commonly called wind spots) are often left on the heated glass in the toughening process due to uneven air blowing, the wind spots of the toughened glass are taken as an index of appearance quality and are more and more concerned by people, and technicians in the industry adopt various modes such as accelerating the glass discharging speed, optimizing the air hole layout, transversely swinging an air grid and the like to reduce the wind spots as much as possible. However, the formation of wind spots is complicated, and in addition to the need for uniform cooling across the width of the apparatus, it is also important to eliminate the formation of wind spots along the length of the apparatus. So far, the wind spot of the toughening furnace is still a flaw of the toughened glass, and people expect a better wind spot weakening technology to ensure that the toughened glass has better appearance.

In order to ensure that the air is uniformly blown in the bending process, the prior art mostly adopts a mode of arranging a row of air boxes on the section bar for blowing, and the rows of air boxes are distributed between the gaps of the flexible shaft roller way. The main reasons for the occurrence of stress spots are: by adopting the wind box and wind grid technology, obvious stress spot marks can be left on the glass due to gaps between the wind boxes, and the attractiveness and the using effect of the glass are seriously influenced.

Original wind box air grid mechanism is fixed through modes such as riveting or bolted connection between the butt joint portion of wind box and the aluminium alloy, and when the flexible air grid that adopts to link up in succession, the above-mentioned mode of reuse is unable butt joint, has two technical problem: the butt joint cannot be completely matched with the external contour of the flexible air grid; and when the flexible air grid is bent along with the arc-changing mechanism, the curvature of the outer surface of the flexible air grid can be changed, and the butt joint part can not be changed into an irregular curved surface.
