Description

Low liquid volume ultrasonic spraying system

Technical Field

The utility model relates to a liquid spraying field, concretely relates to ultrasonic spraying system of low spraying liquid measure.

Background

With the development of nano material technology, the application of nano functional coatings becomes more extensive and is widely applied to the manufacturing fields of metal, glass, textiles, non-woven fabrics, paper and the like, and the functional coatings comprise: super-hydrophobic or super-hydrophilic coatings, thermal barrier coatings, antimicrobial coatings, antireflective coatings, and the like. The industrialization of the preparation of nanoscale films and functional coatings is also increasingly demanded. Conventional coating preparation methods for large-area continuous production type include roll coating, dip coating, blade coating, two-fluid spraying, screen printing, and the like. The coatings prepared by the traditional coating processes such as roll coating, dip coating, blade coating and the like are generally thicker, and the preparation of the nanoscale uniform coating is difficult to realize. Two-fluid spraying causes a large amount of waste of coating due to atomization based on high kinetic energy generated by high-pressure gas and liquid. Screen printing can only produce very thick coatings because of the large amount of liquid coating that can be retained on the screen. And because the atomized particles sprayed by the two-fluid spraying are uneven and the spraying flow rate is uncontrollable, and the precision of roll coating, dip coating, blade coating and screen printing is limited, the uniformity of the obtained coating is poor, and the good functionality of the nano coating is difficult to realize.

The ultrasonic spraying mode is being applied to the preparation of nano-scale films as a novel technology, the amplitude of ultrasonic waves emitted by an ultrasonic transducer is increased through an ultrasonic amplitude transformer, so that liquid or solid particle suspension with high viscosity can be atomized, and liquid mist is uniformly sprayed out by applying compressed gas in a specific trend. The ultrasonic spraying has the advantages of uniform spraying and controllable flow, and can realize the preparation of the film under the normal temperature and pressure environment, so that the large-scale production of the nano-scale film becomes possible.

An automatic ultrasonic spraying system generally moves an ultrasonic spray head through an XYZ three-axis motion module to perform reciprocating spraying on a substrate, and a liquid supply pump is fixed outside the three-axis motion module and connected with the ultrasonic spray head through a liquid conveying pipe. The liquid conveying pipe penetrates through and is fixed on the three-axis movement module, the liquid supply pump is fixed outside the movement module during working, sprayed liquid is conveyed to the ultrasonic spray head through the liquid conveying pipe, and the liquid conveying pipe and the ultrasonic spray head move along with the movement module. This type of tubing tends to be relatively long and requires a relatively large amount of coating fluid to be stored in the tubing. The larger the spraying area is, the larger the length of the three-axis movement module is, so that the larger the length of the liquid conveying pipe is, and more coating liquid is stored. For example, a 100mm by 100mm area may be sprayed, the coating fluid stored in the tubing may be more than 5ml, while the fluid required to actually spray the coating onto the substrate may need only 0.1 ml. This requires a large amount of coating liquid to be sprayed, which is difficult to spray in the case of expensive coatings or insufficient amounts of coating. In addition, the long infusion tube causes the controllability of the liquid supply pump to the liquid to be correspondingly reduced, which often causes unstable liquid supply.

SUMMERY OF THE UTILITY MODEL
