Multi-section linear air knife for toughened glass equipment

Abstract

The invention discloses a multi-section linear air knife for tempered glass equipment. The multi-section linear air knife comprises two fixing plates, the multi-section linear air knife for tempered glass equipment is of U-shaped structure, and the opening end of the U-shaped structure is connected with an air source; the closed end of the U shape is provided with a plurality of rows of narrow slits which are distributed in the length direction, are staggered and mutually pressed and are used for cooling the glass; and the fixing plates, first inclined plates and second inclined plates are connected in sequence. The number of the fixing plates is two. The two fixing plates are symmetrically distributed; the first inclined plates are obliquely fixed at the lower ends of the fixing plates; and the first inclined plates are fixedly connected through the two second inclined plates arranged in an inclined mode. The multi-section linear air knife for tempered glass equipment is compact in structure, reasonable in design and small in occupied space in use, heated glass can be continuously and evenly cooled, the optical distortion defect of the tempered glass is effectively eliminated, andrainbow spots are avoided.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a multi-section linear air knife for tempered glass equipment. Background technique [0002] The cooling grill section is the key core component of the tempered glass equipment, and the optical performance of the tempered glass depends on the structure and arrangement of the air knives of the cooling grill. [0003] The production process of tempered glass requires rapid and uniform cooling of the glass heated to about 700°C. The traditional air hole type cooling grille, because the cooling medium (air) is point-like and discontinuous, will inevitably cause cracks at various points on the glass surface. Inconsistency in the cooling rate will result in stress difference and the formation of stress (rainbow) spots, which will affect the appearance and cause visual obstacles to users, especially in the use of building curtain wall glass and automotive glass.

[0003] The production process of tempered glass requires rapid and uniform cooling of the glass heated to about 700°C. The traditional air hole type cooling grille, because the cooling medium (air) is point-like and discontinuous, will inevitably cause cracks at various points on the glass surface. The cooling rate is inconsistent, resulting in poor stress and forming stress (rainbow) spots, which will affect the appearance and cause visual obstacles to users, especially in the use of building curtain wall glass and automotive glass
