Ubudlelwano phakathi kwe-waveform yenozi yephrinta ye-uv kanye noyinki we-uv bumi kanje: amagagasi ahambisana noyinki abahlukene nawo ahlukile, athintwa kakhulu umehluko wejubane lomsindo likayinki, i-viscosity kayinki, kanye ukuminyana kukayinki.Iningi lama-printheads amanje anamagagasi aguquguqukayo ukuze azivumelanise noyinki abahlukene.
Umsebenzi wefayela le-nozzle waveform: ifayela le-waveform yinqubo yesikhathi yokwenza umsebenzi we-ceramic we-nozzle piezoelectric, ngokuvamile kuba khona unqenqema olukhuphukayo (isikhathi sokuminyanisa sokushaja), isikhathi sokuminyanisa esiqhubekayo (ubude bokuminyanisa), unqenqema oluwayo (ukucindezela isikhathi sokukhululwa), Isikhathi esihlukile esinikeziwe sizoshintsha ngokusobala amaconsi ayinki aminywe umlomo wombhobho.
1.Ukushayela i-Waveform Design Izimiso
Idizayini ye-waveform yeDrayivu ibandakanya ukusetshenziswa kwesimiso sezinto ezintathu zamagagasi.I-amplitude, imvamisa nesigaba kuzothinta umphumela wokugcina weshidi le-piezoelectric.Ubukhulu be-amplitude bunomthelela ejubaneni leconsi le-inki, okulula ukulibona nokulizwa, kodwa umthelela we-frequency (ubude be-wavelength) ngesivinini se-droplet kayinki akusho ukuthi ujulile kakhulu.Ngokuvamile, lolu wushintsho lwejika olunomkhawulo ophezulu (okuningi kakhulu Inani elingcono kakhulu) liyakhethwa, ngakho inani elingcono kakhulu kufanele liqinisekiswe ngokuya ngezici ze-inki ezihlukene ekusetshenzisweni kwangempela.
2. Umthelela wejubane likayinki womsindo ku-waveform
Ivamise ukushesha kunoyinki osindayo.Isivinini somsindo kayinki osuselwe emanzini sikhulu kunesikayinki osuselwe emafutheni.Ekhanda elifanayo lokuphrinta, uma usebenzisa ukuminyana okuhlukile kukayinki, ubude begagasi obulungile kufomethi yayo yegagasi kufanele bulungiswe.Isibonelo, ububanzi be-wavelength bokushayela uyinki osuselwe emanzini kufanele bube buncane kunobukayinki osuselwa kuwoyela.
3. Ithonya le-viscosity ye-inki ku-waveform
Lapho iphrinta ye-uv iphrinta ngemodi yamaphuzu amaningi, ngemuva kokuphela kwe-waveform yokushayela yokuqala, idinga ukuma isikhashana bese ithumela i-waveform yesibili, futhi lapho i-waveform yesibili iqala kuncike ekuzulisekeni kwemvelo kokucindezela kombhobho ngemuva i-waveform yokuqala iyaphela.Ushintsho luvele lubole lube ziro.(I-viscosity ye-inki ehlukile izothinta lesi sikhathi sokubola, ngakho futhi kuyisiqinisekiso esibalulekile se-viscosity ye-inki ezinzile ukuze kuqinisekiswe ukuphrinta okuzinzile), futhi kungcono ukuxhuma lapho isigaba singu-zero, ngaphandle kwalokho ubude begagasi begagasi lesibili buzoshintshwa.Ukuze uqinisekise inkjet evamile, iphinde ikhulise ubunzima bokulungisa i-waveform ye-inkjet engcono kakhulu.
4.Umthelela wenani lokuminyana kukayinki kufomethi yegagasi
Uma inani lokuminyana kukayinki lihlukile, isivinini somsindo wayo sihlukile.Ngaphansi kwesimo sokuthi usayizi weshidi le-piezoelectric lombhobho unqunyiwe, ngokuvamile ubude be-pulse ububanzi be-waveform yokushayela bungashintshwa ukuze kutholwe iphuzu elingcono kakhulu lokushaya kwe-pulse.
Njengamanje, kukhona ama-nozzles anokwehla okuphezulu emakethe yephrinta ye-UV.I-nozzle yasekuqaleni enebanga elingu-8 mm iguqulwa ibe yi-waveform ephezulu ukuze iphrinte u-2 cm.Nokho, ngakolunye uhlangothi, lokhu kuzonciphisa kakhulu isivinini sokunyathelisa.Ngakolunye uhlangothi, amaphutha afana noyinki endizayo kanye nokulandelana kombala kuzophinde kwenzeke kaningi, okudinga izinga eliphezulu lobuchwepheshe labakhiqizi bephrinta ye-uv.
