Vertically advance cauldron car

Abstract

The invention relates to a vertically advance cauldron car, which comprises a glass platform. The vertically advance cauldron car is characterized in that a T-shaped support is fixed on the platform. The two sides of the bottom of the T-shaped support are fixedly provided with square cushion blocks. The upper surfaces of the cushion blocks are provided with a plurality of parallel straight slots. The middle parts of the bottoms of the straight slots are provided with an accommodating groove. A plurality of spaced support rods hang down from two cross beams arranged at the upper part of the T-shaped support. A silicone tube is sleeved onto the lower end of each support rod. The laminated glass of the vertically advance cauldron car is vertically and uprightly stacked onto the advance cauldron car, so that no mutual extrusion force forms between the laminated glass. Therefore, the bowl-shaped optical distortion is eliminated. Meanwhile, oblique-angled cushion blocks at the bottom of the advance cauldron car are improved, and no bubble is generated in a film at the bottom thereof. The laminated glass is attractive and beautiful in appearance.

Description

technical field [0001] The invention relates to the technical field of glass processing, in particular to a vertical kettle feed car. Background technique [0002] Autoclave is the key equipment used for glass interlayer. This equipment makes the film and glass bonded into transparent laminated glass through heat treatment processes such as pressurization and heating. In order to maximize the utilization of the space in the autoclave and maximize the utilization efficiency, the laminated glass is generally pushed into the autoclave by an oblique vertical stacking method. There is an A-shaped bracket on the car, and the laminated glass is stacked on both sides of the A-shaped bracket. The upper and lower ends of the laminated glass are separated by spacers, and a beveled pad is added at the bottom. , so that the bottom as a whole rests on the surface of the bevel block to keep the leaning against the glass stable, see figure 1 shown. However, due to the large size of the g...

Problems solved by technology

However, due to the large size of the glass, when the glass is placed obliquely, the weight is all supported by the upper spacer. When the autoclave is under high temperature and high pressure, the film at the spacer between the inner glass is easy to become thinner due to extrusion. optical distortion

Before the laminated glass enters the autoclave, although the excess film on the glass end face has been trimmed and smoothed, some film will still be squeezed out of the glass end face under pressure in the autoclave, which will make the glass bottom and A-shaped The glue cannot be removed from the place where the bevel pads at the bottom of the bracket are in contact, and if they accumulate together, the gas in the film cannot be removed, and bubbles will form here, such as figure 2 shown

The above problems cause the overall appearance of the finished laminated glass to be poor and unsightly
