Umshini wokuphrinta wesathelayithi we-flexographic, okubizwa ngokuthi umshini wokunyathelisa we-satellite flexographic, owaziwa nangokuthiI-Central Impression Flexo Cindezela,igama elifushaneCI Flexo Cindezela. Iyunithi yokuphrinta ngayinye izungeza i-roller ye-Impression emaphakathi, futhi i-substrate (iphepha, ifilimu, indwangu engalukiwe noma indwangu) isongwe ngokuqinile ebusweni berola emaphakathi ye-Impression, Isivinini esingaphezulu somugqa we-substrate kanye nerola yokuphrinta emaphakathi engaguquki. Lapho okubili kumile ngokuqhathaniswa, okokunyathelisayo kuzungeza ngerola ehlaba umxhwele emaphakathi. Lapho udlula kuyunithi yokuphrinta ngayinye, irola yepuleti lokuphrinta kanye nomshini wokunyathelisa ohlaba umxhwele Ukuphrinta, qedela ukuphrinta okunombala owodwa. I-central Impression roller iyajikeleza, i-substrate idlula kuzo zonke izingxenye zokunyathelisa, futhi ama-plate rollers eyunithi ngayinye yokunyathelisa ahlelwa ngendlela ehlelekile ngokuvumelana nokusatshalaliswa kombala wephethini, futhi ukuphrinta irejista yeyunithi ngayinye yokunyathelisa umbala kuqediwe.

Emshinini wokunyathelisa we-satellite flexographic, i-roller yokucindezela ngokuvamile ifakwe ngaphambi kokuba i-substrate ingene ku-roller ephakathi nendawo, futhi nge-engeli enkulu yokugoqa ecishe ibe ngu-360 °, asikho isihlobo esishelelayo phakathi kwe-substrate ne-roller embossing ephakathi, ngakho-ke akulula ukwelula nokukhubazeka . Ngakho-ke, izinzuzo zomshini wokunyathelisa we-satellite flexographic zinembile futhi zi-overprinting ngokushesha (ikakhulukazi ukuphrinta igolide nesiliva, okungafinyelelwa ngaphandle kwamehlo e-photoelectric), isivinini sokunyathelisa esisheshayo kanye nezinga eliphansi lokwenqatshwa, kanye namafilimu amancane futhi aguquguqukayo. ama-substrates angcono kakhulu. Kodwa-ke, ngenxa yokuthi iqembu ngalinye lombala lihlanganyela i-roller embossing ephakathi, futhi umugqa wokudla phakathi kwamaqembu ombala mfushane, kunzima ukuhlela iyunithi yokumisa isikhathi eside. Ngakho-ke, ikhono lokumisa lepherimitha eligcwele ikhasi lokuphrinta noma uyinki phakathi kwemibala yokuvanisha lingaphansi komphumela wokuphrinta we-flexo wohlobo lweyunithi.

Ngokuvamile, inani lamaqembu ombala wokunyathelisa wemishini yokunyathelisa ye-satellite flexographic ingaphezu kwemibala emine, imibala eyisithupha nemibala eyisishiyagalombili, kanti ububanzi obungaba ngu-1300mm buvame kakhulu. Izici zomshini wokunyathelisa we-satellite flexographic zimi kanje:

① I-substrate iphrintwa ku-roll ngaphandle kokuma, futhi ukuphrinta kwemibala eminingi kungaqedwa ngokudlula okukodwa ngerola yokugqamisa emaphakathi.

②Ukunemba okuphezulu kokubhalisa, kufika ku-±0.075mm.

③Ububanzi berola yokugqamisa emaphakathi bukhulu. Ngokwenani lamaqembu emibala, ububanzi buphakathi kuka-1200 no-3000mm. Ngesikhathi sokuphrinta, indawo yokuxhumana ye-roller ephakathi nendawo ingathathwa njengendiza, ecishe ibe yikhwalithi yokuphrinta ye-round flattening. Ngesikhathi esifanayo, ngenxa yokuthi i-cylinder embossing emaphakathi ilawulwa ukushisa okungaguquki, ilusizo oluhle lokulawula ukucindezela kokuphrinta.

④Ububanzi bokusebenza bezinto zokuphrinta bubanzi kakhulu. Ingakwazi ukuphrinta iphepha elincanyana nephepha eliwugqinsi (28-700g/㎡), futhi ingaphrinta izinto zokuphrinta ezisekelwe kufilimu ezincane kakhulu neziguqukayo, okuhlanganisa i-BOPP (ukunwebeka okubili) kumafilimu epulasitiki. I-polypropylene eyandisiwe), i-HDPE (i-polyethylene ephakeme kakhulu), i-LDPE (i-polyethylene ephansi kakhulu), inayiloni, i-PET (i-polyethylene terephthalate), i-PVC (i-polyvinyl chloride), ne-aluminium foil, njll., ingatholakala umphumela ongcono wokunyathelisa.

⑤Isivinini sokuphrinta esiphezulu, ngokuvamile esingafika ku-250-400m/min, singafika ku-800m/min, sifaneleka ngokukhethekile amaqoqo amakhulu nama-oda amade okuphrinta okukodwa.

⑥ Ibanga phakathi kwemibala lifushane, ngokuvamile li-550-900mm, isikhathi sokulungisa kanye nokuphrinta ngokweqile sifushane, futhi imfucuza yezinto ezibonakalayo incane.

⑦ Ukusetshenziswa kwamandla kungaphansi kwalokho kohlobo lweyunithi. Uma sithatha imodeli yokomisa kagesi engu-8-color 400m/min njengesibonelo, amandla okomisa acishe abe ngu-200kW, kuyilapho uhlobo lweyunithi ye-flexo ngokuvamile ludinga cishe u-300kW.

⑧ Umjikelezo wokwenza amapuleti mfushane. Umjikelezo wokwenza amapuleti weqoqo lamapuleti okuphrinta ama-gravure enemibala eminingi yi-3 ezinsukwini ze-5, kuyilapho umjikelezo wokukhiqiza ipuleti ye-flexographic kuyi-3 kuphela emahoreni angu-24.

Umshini wokunyathelisa we-Satellite flexographic usetshenziselwe kakhulu ukupakisha nokunyathelisa ngenxa yekhwalithi yayo enhle yokunyathelisa, ukusebenza kahle okuphezulu nokuzinza okuhle, ikakhulukazi efaneleka imikhiqizo enamaqoqo amakhulu, izidingo zokunemba okuphezulu kanye nokuguquguquka okukhulu kwezinto zokunyathelisa.
