Indlela yokwenza i-anilox roller ye-umshini wokunyathelisa we-flexographic

Iningi lokunyathelisa kokubili insimu, umugqa, kanye nesithombe esiqhubekayo. Ukuze kuhlangatshezwane nezidingo zemikhiqizo eyahlukene yokunyathelisa, abasebenzisi akumelwe bathathe umshini wokunyathelisa we-flexo onezingxenye ezimbalwa zokunyathelisa ezinezivivinyo ezimbalwa ze-roller. Thatha umshini wokunyathelisa we-flexo weyunithi encane njengesibonelo, okwamanje, ukwethulwa kwe-6+1, okungukuthi amaqembu anemibala ayi-6 okunyathelisa ngemibala eminingi, iyunithi yokugcina inganyatheliswa kanye ne-UV glazing.

Siphakamisa ukuthi uma unyathelisa kungabi ngaphezu kwemigqa engu-150, lo mshini wokunyathelisa we-flexo ongu-6+1 kufanele ufakwe ama-roller e-anilox angu-9. Kusetshenziswa ama-pcs amane ama-roller e-anilox angu-700 anobukhulu obungu-2.3BCM (1 billion cubic micron/inch) kanye no-60° ekunyatheliseni ungqimba. Ama-pcs amathathu emigqa engu-360 ~ 400, i-BCM6.0, i-roller engu-60° yokunyathelisa ensimini; ama-pcs amabili emigqa engu-200, i-BCM15 noma ngaphezulu, i-roller engu-60° yokunyathelisa igolide ne-glazing. Uma usebenzisa uwoyela wokukhanya osekelwe emanzini, kufanele ukhethe i-roller engu-360, ukuze ungqimba lwamafutha lube mncane kancane, ngeke luthinte isivinini sokunyathelisa ngenxa yamafutha okukhanya owomile. I-gloss esekelwe emanzini ayinayo iphunga elikhethekile le-UV gloss. Idivayisi ye-roller ye-anilox inganqunywa ngokuhlolwa nangokuqhathanisa ngesikhathi sokunyathelisa. Ubukhulu bengqimba yeyinki obubonwa ngumsebenzisi enqubweni yokuhlola buncike kakhulu enombolweni yomugqa kanye nenani le-BCM le-roller ye-anilox.

I-Anilox roller enkambisweni yokusebenzisa kufanele inake ukuthi yiziphi izinkinga

Lapha sithi i-roller iyi-laser engraving roller ceramic, isetshenziswa ezindizeni, ezindiza, ekumelaneni nokushisa okuphezulu, ezintweni zokumboza ezimelana nokuguguleka, ngokuya ngobuningi obuthile, ukujula kanye nesimo se-engela ethile, ngokuqoshwa kwe-laser. Le roller ibonakala ngezindleko eziphakeme, ukumelana nokuguguleka, uma isetshenziswa kahle, impilo yayo ingaba iminyaka eminingana; Uma isetshenziswa ngendlela engafanele, hhayi nje kuphela impilo ezofinyezwa, kodwa futhi ne-roller scrap.

Enkambisweni yokusebenzisa, indawo yerola emshinini wokunyathelisa incike ekunyathelisweni okuthile, ukunyathelisa okuhlukile, isikhundla serola sihlukile, ngakho-ke ukunyathelisa kuvame ukuthatha indawo yerola yensimbi. Njengamanje, umshini wobubanzi obuncane usetshenziswa kakhulu kwirola yensimbi eqinile, enzima kakhulu, lapho ufaka irola ukuze ugweme isembozo sobuso berola kwezinye izinto zensimbi. Ngenxa yokuthi ungqimba lwe-ceramic luncane kakhulu, kulula ukudala umonakalo ohlala njalo lapho ushayisana. Enkambisweni yokunyathelisa nokuhlanza umshini, uyinki kufanele ugwenywe erola eyomile, ukuze kusetshenziswe insipho ekhethekile enconywe abakhiqizi beyinki abasebenzisa amanzi, kusetshenziswa ibhulashi lensimbi ukugeza, ukuqinisekisa ukuhlanzwa okuhlanzekile nokuphelele. Futhi uhlakulele umkhuba wokusebenzisa ingilazi ekhulisayo njalo ukuze ubone imbobo yerola, uma usuthole ukuthi ukufakwa kweyinki phansi kwembobo yenethi kanye nokwanda kancane kancane kwesitayela, kufanele kuhlanzwe ngesikhathi. Uma indlela engenhla ingasebenzi, i-ultrasonic noma i-sandblasting ingasetshenziswa ekwelapheni, kodwa kumele kwenziwe ngaphansi kwesiqondiso sabakhiqizi berola.

Ngaphansi kwezimo ezijwayelekile zokusetshenziswa nokugcinwa, asikho isidingo sokukhathazeka ngokuguguleka kwama-roller, izingxenye eziyinhloko zokuguguleka kohlelo lokudlulisa uyinki yi-scraper, ngokuphambene nalokho, ukuguguleka kwe-roller ceramic coating kungathiwa kuncane kakhulu. Ngemva kokuguguleka okuncane kwama-roller, ungqimba lweyinki luzoba luncane.

Buyini ubudlelwano phakathi kwenani lemigqa yenethiwekhi yokuphrinta kanye nenani lemigqa yenethiwekhi yerola

Ezihlokweni eziningi ezethula ubuchwepheshe bokuphrinta be-flexographic, isilinganiso senani lemigqa yenethiwekhi yokuphrinta nenani lemigqa yenethiwekhi ye-roller sibekwe njengo-1∶3.5 noma 1∶4. Ngokusekelwe kokuhlangenwe nakho okusebenzayo kanye nokuhlaziywa kwemikhiqizo enikezwe yi-American Flexographic Technology Association (FTA) eminyakeni yamuva nje, umbhali ukholelwa ukuthi inani kufanele libe phezulu, cishe ngo-1:4.5 noma 1:5, futhi kweminye imikhiqizo yokuphrinta emihle, isilinganiso singase sibe phezulu nakakhulu. Isizathu ukuthi inkinga enzima kakhulu ukuyixazulula lapho usebenzisa ungqimba lokuphrinta lwe-flexographic ukunwetshwa kwamachashazi. I-roller enenombolo ephezulu yemigqa yenethiwekhi iyakhethwa, kanti ungqimba lwe-inki luncane. Ukuguquguquka kokwandiswa kwamachashazi kulula ukulawula. Lapho uphrinta, uma i-inki ingenkulu ngokwanele, ungakhetha i-inki esekelwe emanzini enokugxila kombala okuphezulu ukuqinisekisa ikhwalithi yemikhiqizo yokuphrinta.
