Description

Technical Field

[0001] The utility model relates to a glass tempering furnace in the field of tempered glass, in particular to a high-pressure air grid swinging device for a glass tempering furnace. Background Art

[0002] Wind spots often appear on raw glass after being treated in a tempering furnace. Wind spots are also called stress spots. The internal stress of tempered glass causes the glass to produce double refraction, which is an optical effect caused by grating diffraction. Stress spots appear under polarized or partially polarized light.

[0003] Uneven stress distribution during heating and cooling of tempered glass can cause wind spots. Ensuring uniform heating and cooling can effectively reduce the occurrence of wind spots.

[0004] However, the inventors of this application found that the above technology has at least the following technical problems in the process of implementing the technical solution of the invention in the embodiment of this application:

[0005] Heating factors: The glass is heated unevenly in the plane direction before being cooled and tempered in the tempering furnace. After the unevenly heated glass is cooled and tempered, the high temperature area will produce smaller compressive stress, and the low temperature area will produce larger compressive stress. Uneven heating will cause unevenly distributed compressive stress on the glass surface.

[0006] Cooling factor: The tempering process of glass is to heat and then cool rapidly. The cooling process is as important as the heating process to the formation of tempering stress. Uneven cooling of the glass in the plane direction before cooling and tempering will also cause uneven stress, just like uneven heating.

[0007] In the cooling section of the glass tempering furnace, measures can be taken to reduce the generation of wind spots. After the glass comes out of the furnace, the wind grille should be swung continuously, and the glass should be cleaned in time when it is broken in the wind grille. The wind pressure of the wind grille is determined according to the thickness of the tempered glass. Usually, when the wind pressure is 1000-3000Pa, it is a low-pressure wind grille; when the wind pressure is 8000-10000Pa, it is a high-pressure wind grille. Summary of the invention

[0127] The pad 103 is an L-shaped plate structure, which is located on the upper wind grille 32. A fixing seat 102 is arranged on the pad 103. A screw rod 101 is installed in the middle of the fixing seat 102, and a connecting block 105 is installed on the screw rod 101 and screwed through a nut 104; the connecting block 105 is a rectangular block, one end of which is sleeved on the screw rod 101, and the other end is connected to the upper support hook 8, and is connected to the outer end of the arc-shaped hook 82, forming a support point at the end of the arc-shaped hook 82 to prevent the upper support hook 8 from deforming and shifting; in this embodiment, the anti-deformation fixing component 10 is two pieces to prevent the wind grille 32 connecting plate on which the upper support hook 8 is installed from being deformed due to excessive weight. If the upper wind grille 32 connecting plate is deformed, the resulting phenomenon is that the arc-shaped hook 82 scratches the swinging upper frame 42, causing abnormal noise and deformation. Over time, the upper wind grille 32 and the lower wind grille 31 will swing out of sync.

[0128] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0129] Since the anti-deformation fixing component 10 is located on the upper wind grille 32 through the pad 103 and is connected to the upper support hook 8 through the connecting block 105, it can form a support point for the cantilevered upper support hook 8, enhance the structural stability of the upper support hook 8, and avoid the arc-shaped hook 82 of the upper support hook 8 from scratching the swinging upper frame 42, causing the hidden danger of the swinging upper frame 42 and the swinging lower frame 41 swinging out of sync.

[0130] It is worth noting that the contents not described in detail in the specification belong to the existing technologies known to those skilled in the art, and the model parameters of the lower wind grid worm gear reduction motor 4111, the upper wind grid worm gear reduction motor 4211 and the swing reduction motor 52 are not specifically limited and can be determined using conventional equipment. In this technical solution, the electrical control components not mentioned are not shown in the figure because they belong to the existing technologies and will not be described here.

[0131] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
