A kind of pretreatment device and method for anti-mildew isolation powder used in glass coating production line

Abstract

The invention discloses a mould-proof isolation powder pretreatment device for a glass film plating production line. The device comprises a roller table and a main bracket, wherein the roller table is used for conveying glass; the advancing direction of the glass is from left to right; the main bracket is connected with a brush bracket and an air collecting pipe bracket in the transverse direction from right to left in sequence; the lower ends of the brush bracket and the air collecting pipe bracket are respectively connected with a brush and an air collecting pipe; the brush and the air collecting pipe are positioned above the glass on the roller table; a first sensor and a second sensor are arranged below the glass; the first sensor is positioned at the right side of the brush; and the second sensor is positioned at the left side of the air collecting pipe. Aiming at different glass widths, the part or all opening of an electromagnetic valve is controlled through glass width signals returned by the sensors, so that the jet airflow blows the glass surface with a smallest covering area to achieve the purpose of saving compressed air.

Description

technical field [0001] The invention belongs to the field of auxiliary equipment for a glass coating production line, and in particular relates to a glass pretreatment device and method for cleaning the surface of glass to be coated and jetting compressed air to remove tiny solid particles. Background technique [0002] Before glass coating, the surface to be coated must be clean, otherwise the film will not adhere well to the surface, resulting in film peeling or pinhole defects. Therefore, the cleaning of the glass surface is very important, but also very difficult. At present, the glass coating production line adopts a professional cleaning machine for continuous cleaning of the glass. The cleaning machine uses a combination of ultra-pure water spraying and non-abrasive brush cleaning. The cleaned glass is dried with dry air. This method is currently the most effective cleaning method in the glass coating industry. [0003] However, the glass anti-mildew isolation powde...

Problems solved by technology

[0003] However, the glass anti-mildew isolation powder has strong adhesion and becomes muddy when exposed to water. It is easy to adhere to the roller table and brush of the cleaning machine. At the same time, it will pollute the cleaning water and block the pure water spraying system.

In the end, the anti-mildew isolation powder remaining in the washing machine will cause secondary pollution to the cleaned glass and form defects.

[0004] In addition, after the cleaning machine is contaminated, it must be shut down for cleaning and maintenance, which affects normal production
