[0002] The laminated glass lamination process is to melt the film in the interlayer at a suitable temperature to glue two or more layers of glass together. In order to avoid air bubbles in the interlayer, this process needs to be carried out in a vacuum silicone bag. Silicone bag The silicone suction nozzle is fixedly connected through the vent hole, and the silicone suction nozzle is connected to the vacuum pump through the pipeline. When the vacuum pump is working, the air in the silicone bag is pumped out, but at the same time, the colloid in the melted state is also easily accompanied by the air. It enters the pipeline through the silicone suction nozzle, causing the pipeline to be blocked, resulting in the air in the silicone bag not being discharged normally or completely, resulting in too much remaining air in the bag and affecting the quality of the finished laminated glass. In severe cases, the product may be scrapped. bring economic loss to the enterprise
Another convenience is that due to the small contact area between the silicone suction nozzle and the silicone bag, the airtightness is difficult to guarantee. Once a steam leak occurs, the above situation will also occur

Embodiment Construction
[0014] See attached figure 1 As shown, the vertical shaft 5 is vertically located at the center of the disc 2, both of which are concentric, and are integrally formed of aluminum alloy material. , The vertical shaft 5 is provided with an exhaust hole 1, and the exhaust hole 1 communicates with the air intake hole 4.
[0015] In order to facilitate processing and control the processing accuracy, the air inlet hole 4 is a radial hole of the disc 2 and leads to the center of the disc 2; and the exhaust hole 1 is the central hole of the vertical shaft 5.
[0016] See attached figure 2 As shown, during use, the disk 2 is arranged in the silica gel bag 6, and the bottom is close to the inner wall of the silica gel bag 6, and the two are airtightly matched. The vertical shaft 5 passes through the bag wall, and then connects the vacuum pump through the suction pipe 9. The air is discharged through the air inlet hole 4 and the air outlet hole 1, so that the inside of the silica gel ...

The invention discloses an air suction nozzle for a silica gel bag of interlayer glass equipment, which is characterized by being formed by a circular disc and a vertical shaft which is vertical to the circular disc, wherein the circular disc and the vertical shaft are in an integral structure; a groove is formed in the periphery of the circular disc and the groove is uniformly provided with a plurality of air inlets; the vertical shaft is internally provided with an air exhausting hole; and the air exhausting hole is communicated with the air inlets. The air suction nozzle can prevent fused gel from entering the air suction nozzle and prevents an air exhausting pipeline from being blocked, and all the air in the silica gel is discharged. The air suction nozzle is simple in structure and convenient to operate, and has good air exhausting effect and obvious practical applicability.
