A glass dusting system

Abstract

The invention relates to the technical field of glass processing auxiliary devices, in particular to a glass powder spraying system. The glass powder spraying system comprises a screw powder feeding apparatus installed on a stander, a powder spraying apparatus and a glass conveying apparatus, a closed chamber is arranged above the glass conveying apparatus, the powder spraying apparatus is arranged in the closed chamber, the powder spraying apparatus comprises a venturi powder pump, a powder conveying pipe and spray nozzles which are successively communicated with one another, the screw powderfeeding apparatus comprises a powder storage tank and a shaftless screw powder feeding mechanism, the shaftless screw powder feeding mechanism is used for transporting the isolation powder arranged in the powder storage tank to the venturi powder pump, the isolation powder is sprayed onto the upper surface of glass conveyed on a glass conveying surface of the glass conveying apparatus, and the glass powder spraying system is characterized in that at least two spray nozzles are provided, the two spray nozzles are arranged in parallel along a lateral direction perpendicular to the conveying direction of the glass, a powder outlet of each spray nozzle is in a slit shape, and the length direction of the slit-shaped powder outlet is perpendicular to the glass conveying direction. The glass powder spraying system has the advantages that the powder is uniformly sprayed, the powder spraying efficiency is high, and the powder utilization rate is high.

Description

Technical field: [0001] The invention relates to the technical field of glass processing auxiliary equipment, in particular to a glass powder spraying system. Background technique: [0002] Laminated glass is made of two or more pieces of glass with one or more layers of organic polymer intermediate film between them. A bonded composite glass product. The laminated glass needs to go through the hot bending process before laminating, and the two pieces of glass are laminated together for hot bending (temperature is about 600 ° C). In order to prevent the two pieces of glass from bonding together during the heating and softening process, it needs Spray a layer of isolation powder on the upper surface. [0003] There are two main methods of glass powder spraying, namely wet spraying and electrostatic powder spraying. [0004] Such as the wet spray method proposed in Chinese patent applications 201120520419.1, 201510288887.3, 201520721694.8, etc. After mixing and stirring the...

Problems solved by technology

However, due to the characteristics of small particles of silicon powder that are not easy to charge and agglomerate, conventional powder spraying devices cannot evenly spray silicon powder on the glass surface, which affects the performance and yield of glass.
