A tempered glass production line

Abstract

The invention discloses a tempered glass production line. The tempered glass production line includes a loading table, a heating furnace, an air grid cooling section and a unloading table. The glass plate is carried by a conveying roller table and passes through the above stations in sequence. It is characterized in that the The production line is provided with an air flotation section connecting the outlet end of the heating furnace and the inlet end of the air grid cooling section. The air flotation section includes air flotation devices mirrored above and below the glass plate travel channel. The airflow generated by the device supports the passage of the glass plate and pre-cools the glass plate, which solves the problem that the glass plate is easily bent and deformed when it enters the cooling section of the air grid from the heating furnace, and does not leave roll marks, so that the toughened glass Product quality has been improved.

Description

technical field [0001] The invention relates to a tempered glass production line, in particular to a tempered glass production line in which an air flotation section is arranged at the outlet of a tempering furnace to connect with an air grid cooling section. Background technique [0002] At present, tempered glass production lines such as figure 1 As shown in the figure, it mainly includes a loading table 1, a heating furnace 2, an air grid cooling section 3 and a lowering table 4. The glass plate is carried by the conveying roller table and passes through the above-mentioned stations in turn, and is finally formed. The glass plate directly enters the cooling section of the air grid for cooling and tempering. However, this tempered glass plate production line has some disadvantages in the actual production process: when the glass plate is heated and released from the furnace, the glass plate in the softened state is easy to leave roll marks on the surface of the glass plat...

AI Technical Summary

Problems solved by technology

However, this kind of tempered glass production line has some disadvantages in the actual production process: when the glass plate is heated and released from the furnace, when the glass plate in the softened state passes through the roller table outside the furnace, it is easy to leave roll marks on the surface of the glass plate. At the same time, the edge of the glass plate is deformed, which affects the flatness of the tempered glass plate
