Description
Technical field
The utility model belongs to printing technology, and in particular to a kind of color inkjet printer.
Background technique
By the difference of ink-jet mode, ink jet numbering machine is divided into continuous inkjet technology ink jet numbering machine, drop on demand ink jet technology ink jet numbering machine and heat
Foam ink-jet technology ink jet numbering machine.
For continuous inkjet technology ink jet numbering machine, under the pressure effect of providing ink pump, ink passes through ink road from ink cassette
Pipeline enters spray gun after adjusting pressure and viscosity, and with continuing for pressure, ink is ejected from nozzle, and ink is passing through nozzle
When, fragmented into that a string continuous, spacing is equal and the identical ink droplet of size by the effect of piezo-electric crystal, jet ink flow direction is lower to be continued
It moves across charging pole to be electrically charged, ink droplet is separated from the line of ink marker in charging extremely.Add certain voltage in charging extremely, when
Ink droplet can take and the directly proportional negative electrical charge of pole institute making alive that charges when separating from the conductive line of ink marker in moment.Pass through
The electric voltage frequency for changing charging pole keeps it identical as the frequency of ink droplet fracture, can fill in this way to each ink droplet scheduled
Negative electrical charge, under the continuing of pressure, black stream continues to move downward, and is respectively provided with from two logical among the deflecting plates of generating positive and negative voltage
It crosses, the ink droplet of electrification can deflect when passing through deflecting plates, and degree of deflection depends on how much electrically charged, uncharged ink droplet
It does not deflect, always flight downwards, flows into recovery tube, final recovered pipeline, which returns in ink box, to be recycled.Electrification is simultaneously
The ink droplet of deflection is fallen on the object passed through before vertical spray head with certain speed and angle.
For drop on demand ink jet technology ink jet numbering machine, the ink jet numbering machine of drop on demand ink jet technology is divided into three kinds, piezoelectric ink jet technology, pressure
Valve type ink-jet technology and heat foamable formula ink-jet technology, every kind of working principle be not also identical.
1) piezoelectric ink jet technology: piezoelectric type ink jet numbering machine is called high parsing ink jet numbering machine or high-resolution ink jet numbering machine, integrated
On spray head, multiple a spray orifices on nozzle plate are controlled respectively by 128 or more piezo-electric crystals, by the processing of CPU, then
A series of electric signal is exported to each piezo-electric crystal by driving plate, and piezo-electric crystal is deformed, and such ink is just from nozzle
In eject, fall in mobile article surface, form dot matrix, to form text, number or figure.Then, piezo-electric crystal
It restores to the original state, since ink surface tension acts on, new ink enters nozzle.Because density of ink every square centimeter is very big,
So can be with information such as the text of spray printing high quality, complicated logo and bar codes using piezo technology.
2) pressure valve type inkjet technology: spray head is made of 7 groups or 16 groups high-accuracy intelligent small valve doors, in spray printing,
The character or figure of spray printing export a series of electric signal by output board and give intelligence micro- shape electromagnetism by the processing of computer main board
Valve, valve open and close rapidly, and ink is sprayed by inner, constant pressure at ink dot, and ink dot forms word by spray printing object surface movement
Symbol or figure.
3) thermal foaming inkjet technology: is sprayed in area in ink by the ink less than 0.5% using a thin film resistor
Heating, forms a steam bubble.This steam bubble is spread (less than 10 microseconds) at a terrific speed to be come, and drops out from nozzles is forced to be sprayed
Out.Steam bubble is further continued for into long number microsecond, just disappears and returns on resistor.When steam bubble disappears, the ink of nozzle is just retracted, then table
Face tension can generate suction.
However, traditional continuous inkjet technology ink jet numbering machine and drop on demand ink jet technology ink jet numbering machine, have the following problems: (1)
Ink jet numbering machine has ink cassette and solvent tank, and ink, is exactly diluted to scheduled viscosity, to ensure by the effect of solvent in solvent tank
At code quality, it is therefore desirable to the ink in ink cassette be added in solvent tank, to avoid mixed solvent and ink from being back to
In ink cassette, need to use check valve, and current check valve, structure is complicated, and still has partial reflux, and effect is poor；(2) existing
Some ink jet numbering machines need replacing different print cartridges, use is very inconvenient when printing different colours code.
