Description

Technical Field

[0001] The utility model relates to the technical field of glass processing, in particular to a vacuum extraction device for producing insulating glass. Background Art

[0002] Insulating glass, also known as double-glazed or insulating glass, is designed to improve the thermal insulation performance of windows. Its standard name is "hollow glass" rather than "vacuum glass". During the production process of insulating glass, a near-vacuum state does need to be formed between the two sheets of glass, but it is not a true vacuum, because a complete vacuum will cause negative pressure between the glass, which may cause the glass to break. Therefore, insulating glass usually contains a certain amount of rare gas, such as argon, to reduce heat transfer.

[0003] In the production of insulating glass, there are generally two processing methods. One is to fill the insulating glass with inert gas to achieve thermal insulation and other effects. The other is to extract the gas in the middle of the insulating glass to make it reach a vacuum state. In this way, the transmission medium in the middle can be extracted to achieve better thermal insulation and sound insulation. In order to remove the air in the middle of the insulating glass in a vacuum state during production, it is necessary to use vacuum extraction equipment to extract and discharge it.

[0004] Most of the vacuum extraction equipment for insulating glass production on the market usually replaces the air with hydrogen or nitrogen after extracting it to further improve the thermal insulation performance of the hollow layer. However, different gas cylinders need to be replaced for air supply during the replacement process. During the replacement process, secondary air intake of the insulating glass is inevitable, which means that the vacuum extraction equipment for insulating glass production needs to be improved.

The air pump 16 is arranged at the upper part of the air supply pipe 15, the control valve 1 20 is arranged at the upper part of the air extraction cylinder 18, the control valve 2 21 is arranged at the lower part of the air supply pipe 15, the sleeve 19 is fixedly connected to the middle part of the air extraction cylinder 18, the air supply pipe 15 is connected to the front of the sleeve 19, and the air intake pipe 17 is connected to the outside of the storage box 14.

[0025] Among them, the control valve 1 20 and the control valve 2 21 both belong to existing mature technologies.

[0026] In this embodiment, the lower end of the vacuum extraction base 1 is rotatably connected to a universal wheel 2, and the number of the universal wheels 2 is four.

[0027] In this embodiment, a hollow glass 6 is placed on the upper end of the vacuum extraction base 1 , and a vacuum protection cap 7 is provided on the upper end of the hollow glass 6 .

[0028] In this embodiment, the support frame 3 is fixedly connected to an electric telescopic rod 4, the output end of which is directed toward one side of the insulating glass 6. In this embodiment, the insulating glass 6 is placed on the vacuum extraction base 1, and an exhaust protection cap 7 is provided at the upper end of the insulating glass 6.

[0029] Among them, the vacuum protection cap 7 refers to a device used to protect the interior of a container or equipment from being contaminated by external air, moisture or other gases. This cap can be isolated from the external environment through a vacuum device to ensure that the interior of the container maintains a certain pressure or vacuum state. It is often used in chemical experiments, food preservation, medical packaging and other fields.

[0030] In this embodiment, the output end of the electric telescopic rod 4 is fixedly connected to a clamping block 5, which is a rubber block.

[0031] In this embodiment, a communication hole 22 is opened in the air pump 18, and an air hole is opened at the lower end of the air pump 18.

[0032] In this embodiment, the upper end of the support frame 3 is fixedly connected to an air pump 8 , and both sides of the air pump 8 are connected to an air pump pipe 9 and an exhaust pipe 10 respectively, and the air pump pipe 9 is connected to the air pump box 13 .

[0033] Wherein, the air extraction pipe 9 and the exhaust pipe 10 are both hoses.

[0034] The working principle of the above embodiment is:

[0035] First, place the insulating glass 6 to be processed on the upper end of the vacuum extraction base 1, and drive the clamping blocks 5 on both sides through the operation of the electric telescopic rod 4 to clamp the insulating glass 6, so that the insulating glass 6 can be limited during the processing process to enhance the stability of the equipment processing.

[0036] Secondly, the cylinder 11 is operated to drive the connecting plate 12 to move, and the displaced connecting plate 12 drives the vacuum box 13 and the vacuum cylinder 18 to move. When the vacuum cylinder 18 is connected to the vacuum hole located in the vacuum protection cap 7 on the insulating glass 6, the air inside the insulating glass 6 is extracted through the vacuum pump 8 and the vacuum pipe 9, and then the gas extracted from the insulating glass 6 is discharged through the vacuum pump 8 and the exhaust pipe 10.

[0037] Finally, when the gas in the insulating glass 6 is extracted, the air intake structure is used at this time. The control valve 1 20 is used to block the gas connection between the vacuum cylinder 18 and the vacuum box 13, and the gas is transported to the storage box 14 through the air intake pipe 17. At this time, the control valve 2 21 is opened to connect the air supply pipe 15 with the sleeve 19. The air pump 16 cooperates with the air supply pipe 15 to transport the gas in the storage box 14 to the inside of the sleeve 19, and the gas inside the sleeve 19 will enter the interior of the vacuum cylinder 18 through the connecting hole 22 opened in the vacuum cylinder 18, thereby completing the air supply process of the hollow glass 6 after the air is exhausted, thereby enhancing the practicality and other advantages of the vacuum extraction equipment for the production of insulating glass 6.
