Description
Technical field
The present invention relates to a kind of inkjet technology for spraying ink mist.This inkjet technology is to improve existing ultrasound
Developed on the basis of ripple ink mist jet printing technology.
Background technology
So-called ink-jet printer, exactly forms word or image by the way that ink droplet is ejected on print media.Early stage sprays
The ink-jet printer of black printer and current large format is all to use continuous ink jet technology, and the popular ink-jet of current market
Printer all generally uses random ink-jet technology, and hot bubble type, piezoelectric type, ultrasound are broadly divided into by the type of drive of inkjet printing
Formula and electrostatic.
1999, Japanese scholars Fukumoto delivered " ultrasonic wave ink mist jet printing " on international digital print session,
One text mentions the method for producing very little " ink droplet " using ultrasonic wave effect.Because " ink droplet " size is very small, so that being mutually difficult
Distinguish, be referred to as " ink mist ".Dimensionally ink mist is different from ink droplet, and ink drop size is generally in 10 μm, and each in ink mist
Tiny " ink droplet " is then less than this magnitude, and average diameter is about 2.5 μm.When so tiny " ink droplet " is imaged, can be in paper
It is upper to form the printing image being of high quality.
Misubishi Electric Coporation develop a kind of ultrasonic type inkjet printing be by PZT (piezoelectric transducer),
Dielectric film, black chamber, reflection cavity and nozzle plate are constituted.Dielectric film is covered in PZT (piezoelectric transducer) inner surface, effect be make hearth electrode with
Ink insulation in black chamber.And reflection cavity is made of metal, parabolically type.Reflection cavity is overcoating to be stamped nozzle plate, arranges above
Nozzle.Ultrasonic wave by PZT (piezoelectric transducer) produce, through dielectric film after, along liquid transmissive.Ultrasonic wave focuses on spray by reflection cavity
Near mouth, capilary-tube wave is produced on liquid level, capilary-tube wave can produce the misty liquid droplets of outside injection, when the frequency of ultrasonic wave is
During 10MHz, the liquid-drop diameter of ejection is several microns.
Ultrasonic wave ink mist sprays specific work process：（1）The supersonic detector phase of supersonic generator and industrial circle
Together, it is made up of PZT (piezoelectric transducer)；（2）PZT (piezoelectric transducer) is attached to paraboloid by insulation polyester film, nozzle plate
Position is in the focus of parabolic terrestrial transmitter；（3）PZT (piezoelectric transducer) makes electric energy be converted into mechanical energy under imaging signal excitation, sends out
Go out ultrasonic wave；（4）Ink feed waits swashing for ultrasonic signal to the space formed by ultrasonic transmitter and polyester film
Encourage；（5）High frequency voltage is acted on piezoelectric transducer drives electrode, the ultrasonic wave of generation is delivered to ink, and ink turns into transmission
The medium of ultrasonic wave；（6）PZT (piezoelectric transducer) direction of vibration is vertical with piezoelectric board, ultrasonic wave is vertically delivered to throwing
The surface of thing line interface shape；（7）Ultrasonic energy is changed on parabola, launched, and is gathered on focus point, due to
Nozzle bore is also near parabolic focus position, thus the ultrasonic wave being launched will be focused at the outlet port of nozzle；（8）Assemble
, there is waveform conversion in ultrasonic energy increase afterwards, form the surface wave vertical with ink injection direction in jet expansion position；
(9）Vertical with ink injection direction surface wave direction both sides transmission, the ink higher-order of oscillation in the horizontal direction；（10）In spout both sides
The Sasser edge of ink, the surface tension of ink liquid can not continue to be contacted with parent, and in high density ultrasonic energy
In the presence of, cause part ink to divide with parent, form very tiny vaporific ink droplet group；（11）After the ink mist of jet hole is received
The extruding of face ink and stable state can not be kept, it is spouting from jet expansion；（12）The ink mist for ejecting is by certain
After flying distance, paper surface is transferred to.
Each ink jet unit of ultrasonic wave ink mist injection is required for arranging single driving electrodes that nozzle number is more, drives
Electrode is more, and corresponding drive circuit is more complicated, and cost is higher.
The content of the invention
Present invention aim at a kind of simple structure of proposition, low cost of manufacture, significantly page shower nozzle easily is manufactured into, can not
Nozzle is set, the novel ultrasonic formula inkjet technology of ink mist is ejected at a high speed.
The purpose of the present invention is reached by following measure：The ultrasonic wave that supersonic generator is produced passes through ultrasonic scanning
System, by ultrasonic wave deflection, accommodates in ink gun, and ultrasonic wave directly or indirectly converges to the nozzle of ink gun or connect with air
Near tactile liquid level, ink ejects vaporific ink droplet group in the presence of high density ultrasonic energy.Ultrasonic scanning system is right
Ultrasonic wave carries out controllable deflection and focusing etc., and scan mode mainly has two kinds of mechanical scanning and electron scanning, and mechanical scanning includes
With rotatably, electron scanning is mainly phased configuration to swing type.It is because drop is driven by the ultrasonic wave of direction propagation thus super
Sound formula inkjet printing mode can be not provided with nozzle.
