Ungayenza kanjani i-anilox rollerumshini wokunyathelisa we-flexographic

Iningi lokuphrinta kokubili inkambu, umugqa, nesithombe esiqhubekayo. Ukuze kuhlangatshezwane nezidingo zemikhiqizo yokunyathelisa ehlukahlukene, abasebenzisi akumele bathathe umshini wokunyathelisa we-flexo onamayunithi ambalwa wokunyathelisa ngomkhuba omncane we-roller. Thatha umshini wokunyathelisa weyunithi encane ye-flexo njengesibonelo, okwamanje, ukwethulwa kwe-6 + 1, okungamaqembu angu-6 ombala wokunyathelisa ngemibala eminingi, iyunithi yokugcina ingaphrintwa kanye ne-UV glazing.

Siphakamisa ukuthi ukuphrinta kungabi ngaphezu kwemigqa ye-150, lo mshini wokuphrinta we-flexo we-6+1 kufanele ufakwe ama-9pcs we-anilox rollers. Ama-pcs amane wamarola e-anilox emigqa engu-700 anogqinsi luka-2.3BCM (1 bhiliyoni cubic micron/inch) kanye no-60° asetshenziselwa ukuphrinta ungqimba. 3pcs of 360 ~ 400 imigqa, BCM6.0, 60 ° roller for ukuphrinta field; 2pcs wemigqa engu-200, i-BCM15 noma ngaphezulu, i-roller engu-60° yokuphrinta igolide nokucwebezela. Uma usebenzisa amafutha okukhanya asekelwe emanzini, kufanele ukhethe i-roller yomugqa we-360, ukuze ungqimba lwamafutha lube mncane kancane, ngeke luthinte isivinini sokunyathelisa ngenxa yamafutha okukhanya okomile. Isicwebezelisi esisekelwe emanzini asinalo iphunga elikhethekile le-UV gloss. Idivayisi ye-anilox roller inganqunywa ngokuhlola nokuqhathanisa ngesikhathi sokuphrinta. Ugqinsi longqimba lukayinki olubonwa isisebenzisi kunqubo yokuhlola luncike kakhulu enombolweni yomugqa kanye nevelu ye-BCM yerola ye-anilox.

I-Anilox roller ohlelweni lokusebenzisa kufanele inake ukuthi yiziphi izinkinga

Lapha sithi i-roller i-laser eqoshiwe i-ceramic roller, isetshenziselwa ukuhamba kwezindiza, i-aerospace, ukumelana nokushisa okuphezulu, ukugqoka izinto zokugqoka zokugqoka, ngokusho kokuminyana okuthile, ukujula kanye ne-Angle ethile, ukuma, nokuqoshwa kwe-laser. Le roller ibonakala ngezindleko eziphakeme, ukumelana nokugqoka, uma isetshenziswe kahle, impilo yayo ingaba yiminyaka eminingana; Uma isetshenziswe ngendlela engafanele, hhayi kuphela impilo ezofinyezwa, kodwa futhi ne-roller scrap.

Enkambweni yokusetshenziswa, isikhundla se-roller emshinini wokunyathelisa sincike ekunyatheliseni okuthile, ukuphrinta okuhlukile, indawo ye-roller nayo ihlukile, ngakho ukunyathelisa ngokuvamile kufanele kuthathe indawo ye-roller yocingo. Njengamanje, umshini wobubanzi obuncane usetshenziselwa ikakhulukazi i-roller yensimbi eqinile, enzima kakhulu, lapho ufaka i-roller ukugwema isembozo esiphezulu se-roller kwezinye izinto zensimbi. Ngenxa yokuthi i-ceramic coating incane kakhulu, kulula ukubangela ukulimala okungapheli kumthelela. Enkambweni yokunyathelisa nokuhlanza umshini, uyinki kufanele igwenywe ku-roller eyomile, ukusebenzisa okokuhlanza okukhethekile okunconywa abakhiqizi be-inki abasekelwe emanzini, besebenzisa ibhulashi lensimbi ukugeza, ukuqinisekisa ukuhlanza okuhlanzekile nokuphelele. Futhi hlakulela umkhuba wokuvamise ukusebenzisa ingilazi yokukhulisa ukuphakama ukuze ubheke imbobo ye-roller mesh, uma sekutholakele ukuthi ukufakwa kukayinki phansi kwembobo enezikhala nokwenyuka kancane kancane kwethrendi, kufanele kuhlanzwe ngesikhathi. Uma le ndlela engenhla ingasebenzi, i-ultrasonic noma i-sandblasting ingasetshenziselwa ukwelashwa, kodwa kufanele yenziwe ngaphansi kokuqondisa kwabakhiqizi be-roller.

Ngaphansi kwezimo ezijwayelekile zokusetshenziswa nokugcinwa, asikho isidingo sokukhathazeka mayelana nokugqoka kwe-roller, izingxenye eziyinhloko zokugqoka zesistimu yokudlulisa uyinki yi-scraper, ngokuphambene, ukugqoka kwe-roller ceramic coating kungashiwo ukuthi kuncane. Ngemuva kokugqoka okuncane kwe-roller, ungqimba lukayinki luzoba mncane.

Buyini ubudlelwano phakathi kwenombolo yemigqa yenethiwekhi yokuphrinta kanye nenani lemigqa yenethiwekhi yerola

Ezihlokweni eziningi ezethula ubuchwepheshe bokuphrinta be-flexographic, isilinganiso senani lemigqa yenethiwekhi yokuphrinta enombolweni yemigqa yenethiwekhi ye-roller isethwe njenge-1∶3.5 noma i-1∶4. Ngokusekelwe kokuhlangenwe nakho okungokoqobo nokuhlaziywa kwemikhiqizo eklonyeliswe yi-American Flexographic Technology Association (FTA) eminyakeni yamuva, umbhali ukholelwa ukuthi inani kufanele libe phezulu, cishe 1:4.5 noma 1:5, futhi kweminye imikhiqizo emihle yokuphrinta, isilinganiso singase sibe phezulu nakakhulu. Isizathu siwukuthi inkinga enzima kakhulu ukuyixazulula lapho usebenzisa isendlalelo sokuphrinta se-flexographic ukunwetshwa kwamachashazi. Irola enenombolo ephezulu yemigqa yenethiwekhi ikhethiwe, futhi ungqimba lukayinki luncane. Kulula ukulawula ukunwetshwa kwamachashazi. Uma uphrinta, uma uyinki ungagqinsi ngokwanele, ungakhetha uyinki osuselwe emanzini onombala ophezulu wokugxilisa ingqondo ukuze uqinisekise ikhwalithi yemikhiqizo yokuphrinta.
