Ultrathin toughened glass production line and production method

Abstract

The invention relates to an ultrathin toughened glass production line and a production method. According to the ultrathin toughened glass production line and the production method, driven wheels are fixed to one of the ends of a plurality of rollers placed on the driving shaft on which a plurality of driving wheels in a glass conveying mechanism are fixed at equal intervals, respectively; the faces of the driven wheels are vertical to the faces of the driving wheels; a plurality of photoelectric tubes in a glass measuring device are transversely and densely distributed below an inlet of a heating furnace body; the signal output ends of the photoelectric tubes are connected with the signal input ends of a photoelectric controller in the glass measuring device; the length and the width of the glass are calculated through an optical-electricity encoder; a plurality of high-temperature gas spraying tubes are arranged at equal intervals or unequal intervals on roller conveying channels in the heating furnace body; wind ports are arranged between the rollers in the roller conveying channels in the heating furnace body; air blasting pipes serving as convex nozzle type channels are arranged in an outlet of the heating furnace body; and the outlets of the convex nozzle type channels are opposite to inserting inlets of a quenching device. According to the ultrathin toughened glass production line and the production method, the cooling medium is replaced, thus greater cooling performance is achieved.

Description

technical field [0001] The invention relates to an ultra-thin tempered glass production line and a production method capable of continuously tempering ultra-thin glass with a thickness below 2.5mm, and the tempering standard can meet the national requirements for tempered glass for building materials, and belongs to the field of tempered glass production line manufacturing. Background technique [0002] The traditional continuous tempering furnace is mainly composed of five parts: loading table, preheating section, heating furnace, high pressure section, deceleration section, cooling section and unloading table; plus blower, bellows and air duct, electrical control system and computer terminal etc. facility. The original glass is put into the furnace from the loading table, and goes through the preheating section. Then to the heating section. Heating to a temperature suitable for tempering, then entering the strengthening section for uniform and rapid quenching, and then e...

AI Technical Summary

Problems solved by technology

The quenching process uses the air output by the blower. Because of its low pressure, slow flow rate and high temperature, the number of cooling fans increases, thereby increasing energy consumption and reducing tempering efficiency.

Its shortcomings: first, due to insufficient cooling capacity, it is impossible to temper ultra-thin glass; second, the glass conveying mechanism has poor transmission stability, poor synchronization, and is not easy to detach, and has insufficient ability to deal with emergencies; Entering the furnace and moving forward will cause the temperature of the glass head to be high. Adjusting the temperature in the furnace will have no effect on the glass, resulting in uneven heating temperature of the heated glass surface, and there is a problem of changing the length of the front and rear sides; The roller conveying roller in the furnace body is in line contact with the glass, and the distance between the two rollers is large, which cannot ensure that the heated glass will not be deformed; fifth, the outlet of the main furnace of the heating furnace body is matched with the air grid of the quenching section, and the matching There is a large gap at the place, and the gap will take away the heat of the glass surface that is moving, so the temperature of the glass in the heating furnace body has to be increased, resulting in increased energy consumption and a decrease in the quality of the glass surface; six is ​​the quenching section wind The grid is a passive heat dissipation, completely relying on the wind pressure provided by the air grid to squeeze the hot air away, causing the hot air to stay for a long time, heat is accumulated in the air grid itself, and the temperature of the air grid is high; Seventh, the cooling medium is provided by a blower under a certain pressure. Air, a medium with high temperature, low pressure, and slow flow, resulting in insufficient cooling capacity
