[Umshini wokuphrinta] ingenye yezindlela eziphakeme kakhulu ezisetshenziswa ngayo yonke imishini yemishini yokunyathelisa. Ukuqinisekisa ukusebenza okuvamile komshini wokunyathelisa, ukugcinwa nokugcinwa kahle kwansuku zonke kubalulekile futhi kudingekile kakhulu.
Ukuthatha umshini wokuphrinta isikrini sesandla njengesibonelo, isimiso sokusebenza somshini wokunyathelisa isikrini singachazwa kanje. Ngokusebenzisa indlela yokudlulisela ukudlulisa amandla, ukuze i-scraper ingene
Uyinki onyakazayo we-extrusion kanye nepuleti lokuphrinta isikrini, ipuleti lokuphrinta isikrini kanye ne-substrate ukuze kwakhiwe umugqa wokuphrinta, ngenxa yokushuba kwesibuko i-N1 ne-N2, amandla e-scraper
E2. Ipuleti lokuphrinta lesikrini esinwebekayo ngaphezu komugqa we-imprint alihlangene ne-substrate, uwoyela omnyama ekukhuhleni ukucindezela kwe-blackboard extrusion, ngokusebenzisa inethi, kusukela ekunyakazeni kwengcindezi.
Umugqa wokuphrinta awukho ku-substrate,
Enqubweni yokuphrinta, ipuleti lokuphrinta isikrini kanye nokunyakaza kwesihlobo se-scraper, amandla e-extrusion F1 kanye nokuqina kwe-F2 nakho ukunyakaza okuhambisanayo, isikrini ngaphansi kwesenzo sokuqina, ukubuya ngesikhathi kanye ne-substrate ngaphandle kokuthintana, ukuze ungahlikihli i-imprint engcolile. Okungukuthi screen in the unhlangothi yokunyathelisa, njalo deformation kanye rebound.
Ukuphrinta kwesikrini esingaphezulu kwesikrini esiyisicaba kubhekisela ekuphrinteni kwesikrini endaweni eyisilinda noma eyindilinga enesikrini esiyisicaba. Ngaphansi kwezimo ezithile kungase futhi kube elliptical surface, isigubhu surface. Ukuphrinta isikrini endaweni egobile. Emshinini wokuphrinta wesikrini esingaphezulu kwesikrini ukusetshenziswa kokuphrinta kwesikrini esiyisicaba ebusweni bomshini.
Isimiso sokusebenza somshini wokuphrinta wesikrini esiyisicaba: A – irola eline-B – i-eksisi eno-C – i-mosaic. Lapho uphrinta, ipuleti lesikrini esiyisicaba kanye nokunyakaza kwe-substrate, kanye ne-scraper static. Ipuleti lesikrini esiyisicaba licindezela kuhlaka lwesikrini umshini wokuphrinta wesikrini esigobile esiyisicaba esiqhutshwa ukuhumusha okufanayo, ngenxa yokungqubuzana kwesikrini esibekwe kudivayisi esekelayo ukuzungezisa kwe-substrate. Isivinini somugqa we-substrate engaphezulu kulayini wokugqamisa ihambisana nesivinini esinyakazayo sepuleti lokuphrinta lesikrini esiyisicaba ukuze kuzuzwe ukuphrinta kokuqala.
Ku-efGH engaqukatha ngokugcwele i-ABED emise okwefeni, ipuleti lokuphrinta elihambisana nokumise okwefeni liyenziwa. I-engeli engakwesokudla igxilwe epuletini elithi EFGH, futhi ipuleti lingazungeziswa libe ngelefeni ngo-o njenge-eksisi. Khona-ke kufana nokunyathelisa kwe-cylinder surface, ngaphansi kwepuleti enama-roller angu-4 ukusekela i-substrate, i-scraper ihleliwe, ngokusho kwefreyimu ehambayo ye-fan, ingcindezi ye-scraper ingaba inguqulo ye-conical yokuphrinta kwendawo. Lapho uphrinta, i-conical bearing printing in a some scraper pressure kanye nescreen printing plate line contact; Lapho ipuleti lokuphrinta lesikrini lizungeze i-eksisi yesibalo esimise okwefeni sokunyakaza okuvundlile okumise okukafeni, faka i-substrate yokuzungezisa okuvumelanisa kudivayisi yosekelo: uyinki ku-squeegee, ukuvuza endaweni engaphansi, ukuphrinta okuphelele.
