Embodiment 1

[0013] A method for eliminating wind spots on glass. A number of air grilles are arranged above and below the conveying roller table, and the air grilles are evenly distributed along the glass conveying direction to form a blowing coverage area. During the cooling process, the conveying roller table drives the glass to blow air. Within the coverage area, it moves back and forth along the glass conveying direction; when the moving direction of the glass changes, the air grid is moved to make it move relative to the glass in the direction of glass conveying. When the glass changes its moving direction, the relative movement between the wind grille and the glass is still guaranteed, and it will not stay on the glass surface, which effectively reduces the formation of wind spots. The moving speed of the air grid is equal to the speed of the glass during the reciprocating movement. Make the glass maintain a constant relative speed with the wind grid during the whole process of reci...

Embodiment 2

[0015] Such as figure 1 As shown, an air grid swing mechanism includes a conveying roller table 1, a number of air grilles 2 are arranged above and below the conveying roller table 1, and the air grilles 2 are evenly distributed along the conveying direction of the glass 3 to form a blowing coverage area. During the cooling process, the conveying roller table 1 drives the glass 3 to move back and forth along the conveying direction of the glass 3 within the blowing coverage area; the air grille 2 is movable, and the air grille 2 is connected with a drive that can push the air grille 2 to move back and forth along the conveying direction of the glass 3 mechanism, the drive mechanism is connected with a power mechanism that provides power for it, and the swing mechanism of the air grid 2 also includes a speed detection device (not shown in the figure), which is used to detect the speed of the glass 3 and generate When changed, a signal is sent to the drive mechanism. The moving...

Abstract

The primary purpose of the invention is to discloses a method for eliminating glass wind spots, especially a method for eliminating wind spots formed when glass swinging stops; several wind gratings are disposed above and below a conveying roller; the wind gratings are uniformly distributed in the glass conveying direction to form a wind blowing covering area; during cooling, the glass is driven by the conveying roller to reciprocate in the wind blowing covering area in the glass conveying direction; when the moving direction of the glass changes, the wind gratings are moved to perform relative movement to the glass in the glass conveying direction. At the moment when the glass swings back, the phenomenon of nonuniform stress caused by glass stop is eliminated by the relative movement of the wind gratings. The secondary purpose of the invention is to discloses a wind grating swing mechanism.

Description

technical field [0001] The invention relates to a method for eliminating wind spots on glass, in particular to a method for eliminating wind spots formed on tempered glass by swinging an air grid, and an air grid swing mechanism. Background technique [0002] The tempering process of the tempering furnace will leave stress spots (commonly known as wind spots) on the glass. As an indicator of the appearance quality of tempered glass, wind spots have attracted more and more attention. In order to reduce the wind spots as much as possible, technicians in this industry have adopted A variety of methods, such as accelerating the speed of glass production, optimizing the layout of air holes, and laterally swinging air grilles, etc. However, the formation of wind spots is complicated. In addition to the need to consider the formation of uniform cooling in the width direction of the equipment, it is more important to consider the elimination of the formation of wind spots along the ...
