Description
Technical Field
The utility model relates to a glass tempering technical field, concretely relates to curved surface glass tempering air grid air-out mechanism.
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.
The flexible shaft bent toughened glass toughening furnace consists of an upper sheet table, a heating furnace, a forming toughening unit, a lower sheet table and the like, and all working sections are connected by conveying roller ways with equal-height horizontal conveying surfaces to form a production line.

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.
When the continuous through flexible air grid is adopted to process curved glass in a toughening way, and air flow from the main air supply pipeline blows air from the air inlet of the flexible air grid to the toughened curved glass to be processed through the air outlet of the flexible air grid, the inner wall of the flexible air grid has a plurality of folds, so that fluid resistance can be generated; and because flexible air grid can take place little deformation when the during operation, some air outlets also can take place deformation, only give vent to anger with the air outlet of seting up from its outer wall, the jet direction, the velocity of flow, the flow of air current all have unordered unstability of certain degree, increase the defective percentage.
