Description

Technical Field

[0001] The utility model belongs to the technical field of laminated glass manufacturing, and particularly relates to a vacuum pumping device for an autoclave. Background Art

[0002] Laminated glass is a kind of glass with excellent performance, safety and reliability and is widely used in daily life. Laminated glass is generally made of two pieces of glass firmly bonded with film. The film hot pressing method is generally used to produce laminated glass. The film is added between two or more layers of glass, and then hot pressed in an autoclave after vacuuming. The production process of laminated glass using the film hot pressing method generally includes the following steps: cleaning, joining, pre-pressing, autoclave hot pressing and inspection and packaging.

[0003] However, the existing vacuuming mechanism is often controlled by only one switch valve when vacuuming multiple laminated glasses in the autoclave. When the vacuum sealing mechanism wrapped in a certain laminated glass is punctured, all the laminated glasses cannot be vacuumed, which involves certain risks, wastes time, and has low efficiency and safety. In addition, during vacuuming, due to the different degrees of adhesion between the vacuum sealing mechanism and the laminated glass at different locations, a small amount of gas may easily remain in the gaps formed by the folds of the vacuum sealing mechanism itself, resulting in poor vacuuming effect. Therefore, there is an urgent need for a vacuuming device for an autoclave with good vacuuming effect and high efficiency. Utility Model Content

[0039] The air filling and suction mechanism 6 is detachably connected to the vacuum nozzle of the outer sealing bag 32 .

[0040] like Figure 2 and Figure 7As shown, the vacuum mechanism 2 also includes an elastic pressure measuring member 26, which includes a transparent pressure measuring cylinder 27, a spring 28 and an indicator block 29. The transparent pressure measuring cylinder 27 is connected to the vacuum branch pipe 23, and the spring 28 and the indicator block 29 are detachably connected. The spring 28 and the indicator block 29 are both located in the cavity of the transparent pressure measuring cylinder 27, and the spring 28 is detachably connected to the transparent pressure measuring cylinder 27.

[0041] like Figure 2 As shown, the vacuum pumping mechanism 2 further includes a one-way valve 24 , which is fitted to the side surface of one end of the vacuum pumping branch pipe 23 close to the vacuum pumping main pipe 22 .

[0042] The air-inflating and air-suction mechanism 6 includes an air suction pump, an air suction pipe, an air inflation pump and an air inflation pipe. The vacuum air nozzle of the outer sealing bag 32 includes air nozzle port 1 and air nozzle port 2.

When the outer sealed bag 32 is evacuated, the outer sealed bag 32 forms a secondary protection for the inner sealed bag 31, which greatly improves the safety.
