Rollgang for flat quenches for glass tempering

Abstract

The invention discloses a rollgang for flat quenches for glass tempering, which comprises a rack and multiple conveying rolls, wherein the multiple conveying rolls are parallelly arranged on the rack at certain interval, at least one conveying roll is composed of two sections of rollers, a middle rollgang supporting device is also provided, the middle rollgang supporting device comprises a mounting seat, a mounting frame, a support rod and a sliding bearing pedestal, the mounting frame is connected with the mounting seat, one end of the support rod is fixedly connected with the mounting frame, the other end of the support rod is fixedly connected with the sliding bearing pedestal, a sliding bearing is arranged in the sliding bearing pedestal, the two ends of the sliding bearing are respectively provided with a plane bearing, a connecting head is respectively arranged in inner holes of the sliding bearing and the plane bearings, the two ends of the connecting heads are respectively connected with the two sections of rollers constituting a same conveying roll, and the top end of the sliding bearing pedestal is not higher than the rotary supporting surface of the conveying roll. By using the rollgang disclosed by the invention, the down-warping of the middle part of the rollgang can be eliminated, thereby improving the quality of tempered glass.

Description

technical field [0001] The invention belongs to the technical field of glass tempering, and in particular relates to a conveying roller table of a flat air grid for glass tempering. Background technique [0002] In the glass tempering technology, the roller drive of the large-width flat air grid has a long conveyor roller, and the middle part of the roller table will be deflected. This phenomenon will not only cause the deformation of the tempered glass, but also cause the glass to be heated unevenly. Eventually lead to a decline in the quality of tempered glass. [0003] In the prior art, in glass tempering medium and large-width flat air grid roller table transmission, the method of increasing the diameter of the conveying roller is often used to increase the overall rigidity of the roller table and reduce the downward deflection of the middle part of the roller table. The gap between the nozzle and the roller table, the equipment using this method has to increase the dis...

Problems solved by technology

[0002] In the glass tempering technology, the roller drive of the large-width flat air grid has a long conveyor roller, and the middle part of the roller table will be deflected. This phenomenon will not only cause the deformation of the tempered glass, but also cause the glass to be heated unevenly. Eventually lead to a decline in the quality of tempered glass.

[0003] In the prior art, in glass tempering medium and large-width flat air grid roller table transmission, the method of increasing the diameter of the conveying roller is often used to increase the overall rigidity of the roller table and reduce the downward deflection of the middle part of the roller table. The gap between the nozzle and the roller table, the equipment using this method has to increase the distance between the adjacent conveying rollers, the increase in the distance will make the smaller-sized glass fall into the adjacent conveying rollers and cannot be conveyed, resulting in It is impossible to produce tempered glass products with smaller sizes. In addition, due to the increase in the diameter of the conveying roller, the blowing distance of the corresponding upper and lower air grids to the glass will increase. In this way, it is difficult to ensure the high wind pressure required for thinner glass tempering. At the same time The increase of the distance between the conveying rollers increases the support point of adjacent conveying rollers to the glass, and it is also easy to deform the thinner glass. Therefore, the equipment using this method cannot produce tempered glass products with thinner thickness.
