Adjustable universal wind grating for glass toughening furnace

Abstract

The invention discloses an adjustable universal wind grating for a glass toughening furnace. The adjustable universal wind grating comprises wind grating fixing frames, an upper wind grating body and a lower wind grating body, wherein upper and lower wind grating body lifting mechanisms are arranged on the wind grating fixing frames, and each lifting mechanism comprises motor-driven rising and falling lead screws. The adjustable universal wind grating is characterized by further comprising flank wind gratings arranged at the two sides of the upper and lower wind grating bodies, wherein swinging devices which are used for driving the flank wind gratings to rotate are further arranged on the wind grating fixing frames, and wind guiding ports which communicate with one another are formed in the upper and lower wind grating bodies and the flank wind gratings. According to the adjustable universal wind grating for the glass toughening furnace, disclosed by the invention, the wind gratings are not required to be frequently replaced according to glass of different specifications any more, so that the time and personnel for replacing the wind gratings are saved, the equipment productivity and production efficiency are increased, intelligent control is achieved, and the degree of automation is high; and wind energy can be put into effective use, so that the glass toughening cost is reduced.

Description

Technical field: [0001] The invention relates to a tempered glass production equipment, in particular to an adjustable universal air grill for a glass tempering furnace. Background technique: [0002] The glass tempering furnace is a kind of mechanical equipment for strengthening glass. Generally, the tempering furnace adopts hot air quenching method to process flat glass, that is, the glass is controlled and heated in the tempering furnace to close to the softening point (about 700 ° C), and quickly removed from the furnace. Quenched by high-speed blowing. Toughened glass has 4-6 times greater mechanical strength than ordinary glass and is not easily broken; it also has high thermal stability and can withstand temperatures of about 300°C. When the tempered glass is broken, the fragments are not sharp and angular, but round and obtuse, which is not easy to hurt people. Therefore, tempered glass is widely used in doors and windows of automobiles, trains, ships, etc., surfac...

Problems solved by technology

However, due to the variety of glass types, the shape of the mold and the air grille must match the specific product. Therefore, when the product type is different, the type of cooling air grille is also different, resulting in changing molds and air grilles during the production process. The frequency is very high. Since the upper and lower air grilles are fixed on the fuselage, when replacing the air grilles, it is first necessary to remove the upper and lower air grills by hand, and then fix the air grills that match the production glass at an appropriate position. The operation is cumbersome, and the multiplication of the length of the large air grille has a large area and heavy weight. It is very laborious and time-consuming for employees to replace it, which will take up a lot of production time. On average, the replacement of each pair of air grilles takes more than 98 minutes, accounting for Lost a lot of normal production time and reduced productivity
