Mfundo zamagulu osindikiza a inkjet

1. Chosindikizira cha Inkjet Chokhazikika
Pansi pa kukakamizidwa kwa mpope woperekera inki, inkiyo imadutsa mupaipi ya inki kuchokera ku tanki ya inki, imasintha kupanikizika, kukhuthala, ndikulowa mumfuti ya spray.Pamene kupsyinjika kukupitirira, inki imatulutsidwa pamphuno.Inki ikadutsa mumphuno, imakhudzidwa ndi kristalo wa piezoelectric.Kuthyola mu mndandanda wa madontho a inki osalekeza okhala ndi katayanidwe kofanana ndi kukula kofanana, mtsinje wa inki wonyezimira umapitilirabe kutsika ndipo umaperekedwa kudzera pamagetsi opangira, pomwe madontho a inki amasiyanitsidwa ndi mzere wa inki.Mpweya wina umagwiritsidwa ntchito pa electrode yopangira.Pamene dontho la inki limasiyanitsidwa ndi mzere wa inki wochititsa chidwi, nthawi yomweyo idzanyamula chiwongoladzanja chotsutsana ndi magetsi omwe amagwiritsidwa ntchito pamagetsi opangira magetsi.Ndi kusintha voteji pafupipafupi ma elekitirodi nazipanga izo mofanana pafupipafupi madontho a inki kuswa, aliyense dontho inki akhoza mlandu ndi mlandu anakonzeratu zoipa.Mbale yokhotakhota yokhala ndi voteji yabwino komanso yoyipa imadutsa pakati, ndipo madontho a inki omwe amaperekedwa adzapatutsidwa podutsa mbale yopatuka.Kuchuluka kwa kupatuka kumatengera kuchuluka kwa ndalama.Madontho a inki osalipidwa sadzapatutsidwa, ndipo amawulukira pansi ndikulowa mu chubu chobwezeretsa., ndipo potsirizira pake anabwereranso ku thanki ya inki kuti aigwiritsenso ntchito kudzera papaipi yobwezeretsanso.Madontho a inki opakidwa ndi okhotakhota amagwera pa liwiro linalake ndi ngodya pa zinthu zomwe zimadutsa kutsogolo kwa jeti yowongoka.
2. Dontho Pakufuna
Pali mitundu itatu ya osindikiza a inkjet okhala ndi ukadaulo wofuna ukadaulo wa inkjet, ukadaulo wa inkjet wa piezoelectric, ukadaulo wa valve inkjet, ndiukadaulo waukadaulo wa thovu la inkjet, iliyonse yomwe imagwira ntchito mosiyana.
1) Ukadaulo wa inkjet wa piezoelectric: Chosindikizira cha inkjet cha Piezoelectric chimatchedwanso chosindikizira chapamwamba cha inkjet kapena chosindikizira chapamwamba kwambiri.Pa nozzle Integrated, 128 kapena kuposa piezoelectric makhiristo ntchito kulamulira mbale nozzle.Kupyolera mu processing wa CPU, mndandanda wa zizindikiro zamagetsi zimatuluka ku kristalo aliyense wa piezoelectric kudzera pa bolodi, ndipo kristalo wa piezoelectric ndi wopunduka, kotero kuti inki imatulutsidwa pamphuno ndikugwera pamwamba pa chinthu chosuntha, kupanga. matrix a Dot kuti apange zolemba, manambala kapena zithunzi.Kenaka, kristalo ya piezoelectric imabwerera ku mawonekedwe ake oyambirira, ndipo inki yatsopano imalowa mumphuno chifukwa cha kugwedezeka kwa inki.Chifukwa cha kuchuluka kwa madontho a inki pa lalikulu sentimita imodzi, kugwiritsa ntchito ukadaulo wa piezoelectric kumatha kusindikiza zolemba zapamwamba, ma logo ovuta ndi ma barcode.
2) Chosindikizira cha mtundu wa solenoid valve inkjet (chosindikiza chachikulu cha inkjet): Mphunoyi imapangidwa ndi magulu 7 kapena magulu 16 a vavu yanzeru kwambiri.Mukasindikiza, zilembo kapena zithunzi zomwe ziyenera kusindikizidwa zimasinthidwa ndi bolodi lamakompyuta, ndipo gulu lotulutsa limatulutsa mazizindikiro amagetsi ku valavu yanzeru yooneka ngati solenoid yanzeru, valavu imatsegula ndikutseka mwachangu, ndipo inki imatulutsidwa. madontho a inki ndi kuthamanga kosalekeza kwa mkati, ndipo madontho a inki amapanga zilembo kapena zithunzi pamwamba pa chinthu chosindikizidwa.
3. Thermal Inkjet Technolog
Chidule cha TIJ, chimagwiritsa ntchito chotchinga chochepa kwambiri cha filimu kuti chiwotche zosakwana 0.5% ya inki m'dera la ejection ya inki kuti ipange thovu.Kuwiraku kumakula mwachangu kwambiri (ma microseconds osakwana 10), kukakamiza dontho la inki kuchokera pamphuno.Kuwiraku kumapitilira kukula kwa ma microseconds ena angapo asanazimiririkenso pa resistor.Pamene thovu kutha, inki mu nozzles retracts.Kuthamanga kwapamtunda kenako kumapanga kuyamwa.
