1. Nruam Inkjet tshuab luam ntawv
Nyob rau hauv lub siab ntawm tus number case muab twj tso kua mis, tus number case kis tau los ntawm tus number case pipeline los ntawm tus number case tank, kho lub siab, 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 hla lub nozzle, nws cuam tshuam los ntawm piezoelectric siv lead ua.Kev tawg mus rau hauv cov kab nrib pleb txuas ntxiv nrog qhov sib npaug sib npaug thiab qhov loj me, cov jetted number case kwj txuas ntxiv mus rau hauv qab thiab raug them los ntawm cov khoom siv hluav taws xob, qhov twg cov number case droplets yog sib cais los ntawm tus number case kab.Ib qho voltage yog siv rau lub charger electrode.Thaum tus number case droplet sib cais los ntawm cov kab hluav taws xob conductive, nws yuav tam sim ntawd nqa tus nqi tsis zoo rau qhov voltage thov rau lub charger electrode.Los ntawm kev hloov qhov voltage zaus ntawm lub charger electrode kom nws zoo ib yam li cov zaus ntawm number case droplet tawg, txhua tus number case droplet yuav raug them nrog ib tug predetermined tsis zoo nqi.Lub phaj deflection nrog qhov zoo thiab qhov tsis zoo hluav taws xob dhau los ntawm qhov nruab nrab, thiab cov ntawv ntim cov kua dej yuav raug deflected thaum dhau los ntawm lub phaj deflection.Lub degree ntawm deflection nyob ntawm tus nqi ntawm tus nqi.Cov cwj mem uas tsis tau them nqi yuav tsis raug deflected, thiab yuav ya mus rau hauv qab thiab ntws mus rau hauv lub raj rov qab., thiab thaum kawg rov qab mus rau hauv lub tank kom rov ua dua los ntawm cov raj xa dej rov qab.Cov cwj mem raug them thiab deflected poob ntawm ib qho kev ceev thiab lub kaum sab xis mus rau cov khoom hla pem hauv ntej ntawm lub dav hlau ntsug.
2. Tso rau ntawm Kev Thov
Muaj peb hom inkjet tshuab luam ntawv nrog rau kev thov inkjet tshuab, piezoelectric inkjet tshuab, siab valve inkjet tshuab, thiab thermal foam inkjet tshuab, txhua yam ua haujlwm sib txawv.
1) Piezoelectric inkjet tshuab: Piezoelectric inkjet tshuab luam ntawv tseem hu ua high-resolution inkjet tshuab luam ntawv lossis lub tshuab luam ntawv siab inkjet.Ntawm qhov sib xyaw nozzle, 128 lossis ntau dua piezoelectric crystals yog siv los tswj lub nozzle phaj.Los ntawm kev ua haujlwm ntawm CPU, cov khoom siv hluav taws xob ntau yog tso tawm rau txhua lub piezoelectric siv lead ua los ntawm lub rooj tsavxwm, thiab cov piezoelectric siv lead ua deformed, kom tus number case yog ejected ntawm lub nozzle thiab ntog rau ntawm qhov chaw ntawm cov khoom txav, tsim. Dot matrix los tsim cov ntawv, lej lossis duab.Tom qab ntawd, lub piezoelectric siv lead ua rov qab los rau nws cov duab qub, thiab tus number case tshiab nkag mus rau lub nozzle vim qhov nro ntawm tus number case.Vim hais tias ntawm qhov siab ntom ntom ntawm number case ib square centimeter, daim ntawv thov ntawm lub tshuab piezoelecricum ua tau tuaj yeem luam cov ntawv nyeem zoo, cov cav teeb zoo thiab barcodes.
2) Solenoid valve hom inkjet tshuab luam ntawv (loj cim inkjet tshuab luam ntawv): Lub nozzle yog tsim los ntawm 7 pawg lossis 16 pawg ntawm cov ntse ntse micro-valve.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 lub rooj tsavxwm tso tawm tawm cov khoom siv hluav taws xob rau cov ntse micro-zoo li solenoid valve, lub valve qhib thiab kaw sai, thiab tus number case yog ejected rau hauv. ink dots los ntawm lub siab tsis tu ncua, thiab tus number case dots tsim cov cim lossis cov duab ntawm qhov chaw ntawm cov khoom luam tawm txav.
3. Thermal Inkjet Tshuab
Cov ntawv luv li TIJ, nws siv cov yeeb yaj kiab nyias nyias kom sov tsawg dua 0.5% ntawm tus number case hauv cheeb tsam ejection los ua npuas.Cov npuas no nthuav dav ntawm tus nqi nrawm heev (tsawg dua 10 microseconds), yuam kom tus number case droplet tawm ntawm lub nozzle.Cov npuas txuas ntxiv mus rau ob peb microseconds ntxiv ua ntej ploj mus rau qhov resistor.Thaum cov npuas ploj, tus number case nyob rau hauv lub nozzles retracts.Nto nro ces tsim suction.
