Description

Technical Field

[0001] This utility model relates to the field of insulated glass inflation technology, and in particular to an insulated glass inflation device. Background Technology

[0002] Insulating glass is a high-performance, energy-saving glass product consisting of two or more panes of flat glass sealed together with an aluminum alloy spacer using a high-strength composite adhesive. An internal dry gas layer (air or inert gas) is formed, which provides insulation, sound insulation, and anti-condensation by blocking heat conduction and convection. It is widely used in energy-efficient building curtain walls, high-end doors and windows, and automotive windshields.

[0003] The production process of insulated glass involves multiple steps. First, float glass, Low-E glass, or tempered glass is selected, laser-cut, and then cleaned with deionized water. Second, the spacer strip is made of aluminum or composite adhesive strip, with a built-in molecular sieve desiccant, and is processed into a rectangular frame using a bending machine. Then, the two panes of glass are aligned with the spacer strip, and the first seal is completed using a butyl sealant coating machine, followed by the injection of polysulfide sealant or silicone sealant to form a second seal. Finally, during the lamination process, inert gases such as argon are injected into the gas chamber using a gas filling device, and then the glass enters the curing chamber to complete the curing of the adhesive.

[0004] The existing insulated glass inflation device has the following problems: After the insulated glass assembly is completed, valves are set at the top and bottom corners on both sides. After inflation, since the difference between the internal and external air pressure is not large, the air tightness is judged only by the change in the internal air pressure, which has a large error. Insulated glass with poor air tightness, inert gas will slowly leak out from tiny cracks, thus affecting the inflation effect of the insulated glass. Utility Model Content

At this time, the second motor 13 is started. The rotation of the second motor 13 drives the gear 12 to rotate. The gear 12 and the gear ring 11 mesh with each other. The gear 12 drives the gear ring 11 to rotate, thereby driving the U-shaped frame 10 to rotate.

The filter screen 39 filters the impurities in the water, and the water pump 26 continuously pumps the filtered clean water back into the water tank 21 through the return water pipe 24, thereby maintaining the water level in the water tank 21. This allows the operator to observe the overflow of bubbles from outside the water tank 21.
