Heavy-Duty Precision Roller Coating Machine for Glass

Working Principle

The heavy-duty precision roller coating machine for glass adopts a heavy-duty frame and a high-precision transmission system, suitable for the stable conveyance of large-size and thick-specification glass. Through the precise contact between the precision coating system and the glass surface, the machine achieves quantitative transfer of coating materials. Its core advantages include controllable film thickness, uniform coating without defects, support for continuous high-speed operation, coating utilization rate of over 95%, and environmental protection with low VOC emissions, making it more competitive in efficient production.

Structural Composition

Conveying System: Composed of a conveyor belt, drive motor, etc., it is used to transport glass sheets and make them pass through the roller coating area smoothly. The speed of the conveyor belt can usually be adjusted by a frequency converter to meet different coating process requirements of the machine.

Coating System: As the core part of the machine, it includes coating rollers, metering rollers, coating tanks, etc. The material and surface treatment process of the coating rollers and metering rollers have a significant impact on the coating effect. Usually, the coating rollers are made of solvent-resistant and wear-resistant materials such as polyurethane to ensure the coating quality of the machine.

Transmission System: Composed of motors, reducers, gears, chains, etc., it is used to drive the operation of components such as coating rollers, metering rollers, and conveyor belts. By ensuring the speed matching and stable operation between various components, it provides power support for the efficient operation of the machine.

Control System: Including electrical control cabinets, PLC, touch screens, etc., it can realize the setting and monitoring of various parameters of the machine. For example, coating speed, coating thickness, pressure of the coating circulation system, etc., to ensure the precise control and stable operation of the machine's roller coating process.

Coating Circulation System: Composed of oil pumps, filters, oil storage tanks, etc., it can recover and filter excess coating, then transport it back to the coating tank for recycling. This design reduces coating waste and further improves the economy of the machine.

Application Fields

The heavy-duty precision roller coating machine for glass is widely used in fields such as architectural glass, photovoltaic glass, home appliance glass, and display panel glass. It can meet mass production needs and high-quality coating standards, and is an important equipment in the glass deep processing industry.
