Principle classification yeinkjet printers

1. Inopfuurira Inkjet Printer
Pasi pekumanikidzwa kwepombi yekupa inki, inki inopfuura nepapombi yeinki kubva mutangi yeinki, inogadzirisa kudzvinyirira, viscosity, uye inopinda mupfuti yepfapfaidzo.Sezvo kudzvinyirira kunoramba kuchienderera mberi, inki inobudiswa kubva mumuromo.Kana iyo inki ichipfuura nemumuromo, inobatwa neiyo piezoelectric crystal.Kutyora kuita nhevedzano yemadonhwe einki anoenderera ane nzvimbo yakaenzana uye saizi yakafanana, jeti ingi inoyerera inoramba ichidzika ichidzika uye inochajiswa kuburikidza neelectrode yekuchaja, apo madonhwe einki anoparadzaniswa kubva pamutsetse weinki.Imwe voltage inoshandiswa kune electrode yekuchaja.Kana iyo ingi droplet inoparadzaniswa kubva kune conductive inki mutsetse, ichaita pakarepo kutakura yakaipa charge proportional kune voltage inoshandiswa kune electrode yekuchaja.Nekuchinja frequency yevoltage yekuchaja electrode kuti iite yakafanana neiyo frequency yemadonhwe einki kuputsika, imwe neimwe inki droplet inogona kuchajwa nechaji yakafanotemerwa yakaipa.Iyo deflection plate ine yakanaka uye yakaipa voltage inopfuura nepakati, uye inochaja inki madonhwe anozotsauka kana achipfuura nepakati peplatection.Iyo dhigirii yekutsauka inoenderana nehuwandu hwekuchaja.Madonhwe einki asina kubhadhariswa haazotsauswi, uye anobhururuka achidzika uye anoyerera muchubhu yekudzoreredza., uye pakupedzisira akadzokera kutangi reinki kuti ishandiswe zvakare kuburikidza nepombi yekudzokorodza.Madonhwe eingi anochajirwa uye akatsauka anowira pane imwe sipidhi uye kona pane zvinhu zvinopfuura pamberi pejeti yakatwasuka.
2. Drop On Demand
Kune marudzi matatu einkjet anodhinda ane on-inoda inkjet tekinoroji, piezoelectric inkjet tekinoroji, pressure valve inkjet tekinoroji, uye tekinoroji yefoam inkjet tekinoroji, imwe neimwe inoshanda zvakasiyana.
1) Piezoelectric inkjet teknolojia: Piezoelectric inkjet printer inonziwo high-resolution inkjet printer kana high-resolution inkjet printer.Pamuromo wakabatanidzwa, 128 kana kupfuura piezoelectric makristasi anoshandiswa kudzora ndiro yenozzle.Kuburikidza nekugadziriswa kweCPU, nhevedzano yemagetsi masaini anoburitswa kune yega piezoelectric crystal kuburikidza nedhiraivha bhodhi, uye piezoelectric crystal yakakanganiswa, zvekuti ingi inoburitswa kubva mumuromo uye inowira pamusoro pechinhu chinofamba, ichigadzira. a Dot matrix kugadzira zvinyorwa, nhamba kana mifananidzo.Zvadaro, piezoelectric crystal inodzokera kuchimiro chayo chepakutanga, uye inki itsva inopinda mumuromo nekuda kwekunetseka kwepamusoro kwengi.Nekuda kwekuwanda kwehupamhi hweinki dots pa square centimita, kushandiswa kwepiezoelectric tekinoroji inogona kudhinda zvinyorwa zvemhando yepamusoro, logos yakaoma uye mabhakodhi.
2) Solenoid valve type inkjet printer (hombe character inkjet printer): The nozzle inoumbwa ne7 groups or 16 groups of high-precision intelligent micro-valve.Pakudhinda, mavara kana magirafu achadhindwa anogadziriswa nekombuta yaamai, uye Iyo inobuda bhodhi inoburitsa nhevedzano yezviratidzo zvemagetsi kune yakangwara micro-shaped solenoid valve, vharuvhu inovhura nekuvhara nekukurumidza, uye inki inoiswa mukati. madoti einki kubudikidza nekudzvanywa kwemukati, uye madotsi einki anoumba mavara kana mifananidzo pamusoro pechinhu chakadhindwa chinofamba.
3. Thermal Inkjet Technolog
Yakapfupikiswa seTIJ, inoshandisa firimu rakatetepa rekudzivirira kupisa isingasviki 0.5% yeinki munzvimbo yeinki ejection kuita bubble.Iri bhobho rinokura nekumhanya zvakanyanya (zvisingasviki gumi mamicroseconds), zvichimanikidza kudonhedza inki kubva mumuromo.Iyo bubble inoramba ichikura kwemamwe mashoma mamicroseconds isati yanyangarika ichidzokera pane resistor.Apo mabhubhu anonyangarika, ingi iri mumhino inodzosa.Surface tension inobva yagadzira kuyamwa.
