Roller way mechanism used for conveying calendered flat plate glass

Abstract

The invention relates to a roller way mechanism used for conveying calendered flat plate glass. A front transmission chain and a back transmission chain which are in parallel arrangement are used fordriving a roller in a roller way, so that a load required for roller driving is distributed onto two transmission chains, so that the load required to be borne by each transmission chain is smaller; therefore the specification of the front transmission chain and the back transmission chain can be small, so that the installing space of the transmission mechanism can be further reduced. Therefore the space between rollers in the roller way can be further reduced; the contact area between the glass plate and the rollers can be larger and more uniform; the glass plate cannot easily deform, so thatthe flatness degree of the produced glass plate can be improved.

Description

technical field [0001] The invention relates to a roller table mechanism for conveying rolled flat glass, in particular to a roller table mechanism used for conveying flat glass in a rolling annealing kiln. Background technique [0002] In the existing calendering annealing kiln roller tables, rollers with a diameter of φ150mm~φ160mm are generally used, and the transmission of the rollers adopts the structure of gear transmission. Since the transmission of the gear structure will occupy part of the space between adjacent rollers, therefore, adjacent The distance between the rollers is controlled between 240mm and 260mm. The glass produced by this kind of calendering line meets the requirements for conventional thick glass plates, but for glass plates with a thickness of less than 2mm on the surface, the glass produced by this roller spacing is not high in surface flatness and large in undulations, which meets the requirements. The reason is that the temperature of the rolli...

Problems solved by technology

The glass produced by this kind of calendering line meets the requirements for conventional thick glass plates, but for glass plates with a thickness of less than 2mm on the surface, the glass produced by this roller spacing is not high in surface flatness and large in undulations, which meets the requirements. The reason is that the temperature of the rolling annealing kiln is high, and the glass ribbon in this area is still in an elastic-plastic state. For the roller distance of 240mm to 260mm, the glass surface will collapse and collapse in the gap between adjacent rollers. Undulations, and cannot be completely eliminated by annealing in the subsequent process, thus affecting the surface quality of the glass
