Description
Technical field
This application involves inkjet printing technology fields more particularly to a kind of nozzle maintenance method, device, equipment and storage to be situated between
Matter.
Background technique
Digital printing is a kind of printing technology emerging in recent years.Refer to the biometrics of some or all of overall process.Number
Code printing is that computer document is directly printed on paper, is different from the completely new printing of one kind of the cumbersome technical process of traditional printing
Mode.Digital printing has numerous advantages such as simple, quick, flexible, it and traditional printing are the difference is that digital printing can
It is variable with a Zhang Qiyin, data, also picture and text can be made to be propagated by various media, substantially increase digital image-forming uses model
It encloses.With the development of the times, specific gravity of the digital printing in printing industry is also increasing.
Representative of the ink jet printing as digital printing, is widely used in books and periodicals, label, commercial affairs, packaging and specialty printing etc.
Aspect.More and more equipment suppliers start to put into the research and development of high-speed inkjet printing equipment.Ink jet printing is a kind of nothing
Contact, no pressure, the printing without printing plate.Relative to electrostatic/laser, magnetic powder be imaged, ink jet printing resolution ratio, print speed printing speed,
There is significant advantage in terms of cost, and mode of printing is more environmentally friendly.Ink jet printing can be divided into continuous inkjet by the difference of ink-jet mode
With drop on demand ink jet two ways, continuous inkjet refers to that liquid ink passes through a small circular nozzle under pressure, by height
Frequently successional ink stream is generated, then is separated into single ink droplet and takes electrostatic, then under the control of image information, ink droplet
It is injected on stock or is transferred recycling.Drop on demand ink jet refer to according to facsimile signal make in drops out from nozzles spray and immediately
On the substrate, the ink droplet of nozzle supply only just sprays when needed, and drop on demand ink jet is than continuous inkjet high resolution for attachment.Into one
Step ground, drop on demand ink jet are subdivided into heat foamable formula and piezoelectric type.Heat foamable formula refers to that the side of print head ink chamber is heating plate,
The other side is spray orifice, and heating board is brought rapidly up the boiling point higher than ink under the function of current that facsimile signal controls, with heating
Bubble is formed after the ink vaporisation that plate directly contacts, bubble sprays ink from spray orifice full of inking chamber, reaches stock, then
Heating plate cools down inking chamber, is refilled by capillarity by accumulator.Piezoelectric type refer to using the vibration of piezo-electric crystal come
Generate ink droplet.Pressure pulse is applied on ink by piezo-electric crystal, and when piezoelectricity generates pulse, piezo-electric crystal deforms, shape
At the pressure of ink-jet, to form ink droplet, fly out to form picture and text.Piezo-electric crystal restores to the original state, and refills ink in inking chamber
Water.
In simple terms, ink-jet printer is made of system controller, inkjet controller, spray head, stock driving mechanism etc..
Ink sprays, spray printing is on the substrate under the control of inkjet controller from the nozzle of spray head.Spray head as ink jet printing one
A important composition unit, construction is complicated, and in order to ensure the consistency of crystal, is disposably processed using bulk crystal, to production
The requirement of technique is very high, so the cost specific gravity of spray head is larger in entire ink-jet system.In actual printing process (with
For book and periodical printing), in addition to the little particle in environmental factor, such as ink, dust small in air cause the blocking of nozzle
Outside, most of situation is not sprayed for a long time since ink is chronically in nozzle, leads to loss of moist in ink, ink
Water-setting consolidates plug nozzle.For example, the centre of the books and periodicals space of a whole page, due to being the part of spine, so being left white, comparison is more, and correspondence is sprayed in this way
Mouth will not spray ink droplet for a long time, this region is caused to gag somebody than more serious over time.It is general it is slight gag somebody, pass through and be
The included blow head maintenance operating process of system just can solve.It is serious just to need to disassemble in spray head to clean, for example use
Ultrasonic cleaning.It is serious again to gag somebody, it safeguards, clean and not can solve, which can only just scrap processing.
