Inkjet Printer Principle Classification

1. Nruam Inkjet tshuab luam ntawv
Nyob rau hauv lub siab ntawm tus number case mov twj tso kua mis, tus number case ntws los ntawm tus number case tank los ntawm tus number case yeeb nkab, kho lub siab thiab viscosity, thiab nkag mus rau hauv cov tshuaj tsuag phom. Thaum lub siab txuas ntxiv, tus number case yog ejected los ntawm lub nozzle. Thaum tus number case dhau los ntawm lub nozzle, nws tau tawg mus rau hauv ib qho kev sib txuas ntawm tus number case tas li nrog qhov sib npaug sib npaug thiab qhov loj tib yam los ntawm kev ua ntawm piezoelectric siv lead ua. Lub ejected number case ntws mus txuas ntxiv mus rau hauv qab thiab dhau los ntawm lub charger electrode yuav tsum tau them. Nyob rau hauv lub charger electrode, tus number case droplets yog cais los ntawm tus number case kab. Ib qho voltage yog siv rau lub charger electrode. Thaum tus number case droplets raug cais los ntawm cov kab hluav taws xob conductive, lawv yuav tam sim ntawd nqa tus nqi tsis zoo uas yog proportional rau voltage thov rau lub charger electrode. Los ntawm kev hloov qhov voltage zaus ntawm lub charger electrode kom nws tib yam li qhov zaus ntawm tus number case droplet breakage, txhua tus number case droplet yuav raug them nrog ib tug predetermined tsis zoo nqi. Nyob rau hauv lub siab tas mus li, tus number case ntws mus txuas ntxiv mus rau hauv qab thiab dhau los ntawm nruab nrab ntawm ob daim hlau deflection nrog qhov zoo thiab tsis zoo voltages feem. Cov kua dej uas tau them tus number case yuav deflect thaum hla lub phaj deflection. Lub degree ntawm deflection nyob ntawm tus nqi ntawm tus nqi. Cov kua dej uas tsis tau them nqi yuav tsis thim rov qab thiab yuav ya mus rau hauv txhua txoj kev, ntws mus rau hauv cov yeeb nkab rov qab, thiab thaum kawg rov qab mus rau hauv lub tank los ntawm cov yeeb nkab rov qab los siv dua. Cov kua nplaum uas raug them thiab deflected poob rau ntawm cov khoom hla ntawm lub taub hau ntsug ntawm ib qho ceev thiab lub kaum ntse ntse.
2. Drop On Demand Technology
Muaj peb hom tshuab luam ntawv inkjet nrog kev xav tau thev naus laus zis: piezoelectric inkjet thev naus laus zis, siab valve inkjet tshuab, thiab thermal foaming inkjet tshuab. Lub hauv paus ntsiab lus ua haujlwm ntawm txhua tus kuj txawv.
1) Piezoelectric inkjet tshuab: Piezoelectric inkjet tshuab luam ntawv tseem hu ua high-resolution inkjet printers lossis high-resolution inkjet printers. Ntawm qhov sib xyaw nozzle, 128 lossis ntau dua piezoelectric crystals tswj ntau lub nozzles ntawm lub phaj nozzle. Tom qab ua tiav los ntawm CPU, cov teeb liab hluav taws xob tau tso tawm rau txhua lub piezoelectric siv lead ua los ntawm pawg tsav tsheb. Lub piezoelectric crystals deform, yog li ntawd tus number case yog ejected los ntawm lub nozzle thiab ntog rau saum npoo ntawm cov khoom txav mus rau hauv ib tug dot matrix, yog li tsim cov ntawv, cov zauv los yog cov duab. Tom qab ntawd, cov piezoelectric siv lead ua rov qab los rau nws qhov qub, thiab vim yog qhov nro ntawm tus number case, tus number case tshiab nkag mus rau lub nozzle. Vim tias qhov ntom ntom ntawm number case dots ib square centimeter siab heev, daim ntawv thov ntawm piezoelectric technology tuaj yeem luam cov ntawv zoo, cov logos, barcodes thiab lwm yam ntaub ntawv.
2) Solenoid valve inkjet tshuab luam ntawv (loj cim inkjet tshuab luam ntawv): Lub nozzle muaj 7 lossis 16 pawg ntawm cov ntse ntse micro li qub. Thaum luam ntawv, cov cim lossis cov duab uas yuav tsum tau luam tawm yog ua tiav los ntawm lub khoos phis tawj motherboard, thiab cov khoom siv hluav taws xob tau tso tawm mus rau lub ntse micro solenoid valve los ntawm lub rooj tsavxwm tso tawm. Lub valve qhib thiab kaw sai sai, thiab tus number case yog ejected rau hauv number case dots raws li lub siab tas li. Cov cwj mem dots tsim cov cim lossis cov duab kos rau ntawm qhov chaw ntawm cov khoom luam tawm txav.
3. Thermal Inkjet Technology (TIJ)
Luv luv li TIJ, nws siv cov yeeb yaj kiab nyias nyias kom sov tsawg dua 0.5% ntawm tus number case nyob rau hauv cheeb tsam ejection los ua npuas. Cov npuas no nthuav dav ntawm qhov ceev ceev heev (tsawg dua 10 microseconds), yuam kom cov kua dej ntws tawm ntawm lub nozzle. Cov npuas txuas ntxiv loj hlob rau ob peb microseconds thiab tom qab ntawd ploj mus rau qhov resistor. Thaum cov npuas ploj lawm, tus number case hauv lub nozzle retracts. Ces qhov nro saum npoo yuav tsim suction.
