Technical Field

[0001] The utility model relates to a coating production device, in particular to a large-area silver mirror coating coating production device, belonging to the technical field of coating production. Background Art

[0002] Glass coating technology, mainly a chemical process under atmospheric conditions. For large-area glass, chemical silver plating is widely used because the equipment is simple and easy to operate, and the silver mirror surface is clear and corrosion-resistant.

[0003] The traditional silver film process is to pre-plating silver film on the glass as a sensitization preparation stage. Once the glass surface has conductive properties, the silver film can be deposited autocatalytically.

[0004] For example, the existing patent application No. 200920058761.7 is a large-area silver mirror coating production line device, which is a production line composed of various equipment, including the following equipment: pre-cleaning equipment-polishing machine (1)-roll washing machine (2)-spraying machine (3)-air drying equipment-glass drying equipment-painting machine (5)-drying machine (4)-air cooling equipment-painting machine (5)-drying machine (4)-air cooling equipment-pickling equipment-cleaning equipment-air drying equipment. The connecting rod on the polishing machine adjusts the height of the grinding disc at the same time; the upper and lower brushes of the roller washing machine are driven separately, and the height of the brushes is adjusted by a screw; the several nozzles of the spraying machine are pulled by a synchronous belt; and four small oven covers are installed on the dryer.

[0005] However, in the existing silver mirror coating processing, the traditional processing method of spraying paint liquid with a nozzle is adopted. However, the paint liquid sprayed by the nozzle will present a cone shape with a small top and a large bottom. It is easy for the paint liquids sprayed by two adjacent nozzles to cross and overlap each other, resulting in uneven distribution of paint liquid thickness, which affects the processing quality.

A flow controller 6 is fixedly connected to the top of the storage box 7.

[0028] When the utility model is in use: the drying device 15 is arranged on one side of the mounting frame 2 and installed on the top of the conveying device 1 .

[0029] A mounting frame 2 is fixedly connected to the top of the conveying equipment 1, and the bottom end of the telescopic pneumatic cylinder 14 fixedly connected inside the mounting frame 2 is fixedly connected to the storage box 7, so the telescopic pneumatic cylinder 14 is controlled to work, and the telescopic pneumatic cylinder 14 controls the upper and lower positions of the storage box 7. After the telescopic pneumatic cylinder 14 is controlled to push the storage box 7 to the working position downward, the telescopic pneumatic cylinder 14 stops working.

[0030] At this time, the bottom of the storage box 7 is set on the top of the silver mirror transported by the conveying equipment 1, and then the water pump 3 fixedly installed on the top of the mounting frame 2 is controlled to work.
