izindaba

Ama-roller enjoloba womshini wokuphrinta (kufaka phakathi ama-roller amanzi kanye nama-inki roller) adlala indima ebalulekile enqubeni yokuphrinta, kepha ekukhiqizeni kwangempela, izinkampani eziningi zokuphrinta zizothatha indawo yama-roller wenjoloba wangempela ngemuva nje kokuba zisetshenzisiwe. Iningi labakhiqizi linokuhlanza okwanele kanye nokugcina amasondo enjoloba, okuholela ekugugeni ngaphambi kwesikhathi kwama-roller werabha wangempela, okuholela ekwehlulekeni kokuphrinta nasekulahlekelweni kwezindleko. Mayelana nalokhu, lo mbhalo wenza uhlu olukhulu lwezizathu zokugqokwa kwamaroli enjoloba wokunyathelisa, futhi ngasikhathi sinye wabelana ngamathiphu ayi-10 wokugcinwa kwamaroli werabha.
Izizathu
Enkambisweni yokusebenzisa iroli yerabha yomshini wokuphrinta, ngenxa yokusetshenziswa okungafanele noma ukusebenza, impilo yeroli yenjoloba izofinyezwa noma ilimale. Yiziphi izizathu?
Ukulungiswa okungafanele kwengcindezi ye-roller roller kuzokwenza ukuthi i-roller roller iphele, ikakhulukazi uma ingcindezi inzima ngakolunye uhlangothi futhi ikhanya ngakolunye uhlangothi, kulula ukudala umonakalo ku-roller yerabha.
You Uma ukhohlwa ukuvala izibambo kuzo zombili iziphetho zensimbi ebhakedeni lamanzi, ingcina ye-metering roller izoklebhuka futhi ilimale. Uma umkhawulo owodwa ungavaliwe noma omunye umkhawulo ungekho endaweni, kuzodala ukuthi i-roller yemitha kanye ne-roller yamanzi isekele ukugqoka.
③ Ngesikhathi senqubo yokulayisha ipuleti le-PS, ipuleti le-PS alikho endaweni futhi izikulufo zokudonsa ekulungeni nasemsileni wepuleti le-PS aqinisiwe. Ipuleti le-PS lizoguga i-roller yerabha ngenxa yengxenye engafakwanga untambo kanye nezingxenye eziyize neziphumayo; ngasikhathi sinye, kudonswa ipuleti lePS. Uma ipuleti ephezulu icinene kakhulu noma ipuleti ephezulu iqine kakhulu, izodala ukuthi ipuleti likhubazeke noma liphule futhi lidale umonakalo ku-inki roller, ikakhulukazi ubulukhuni benjoloba obuphansi be-roller inki, futhi umonakalo ubonakala kakhulu.
④ Ngesikhathi senqubo yokuphrinta, lapho kuprintwa ama-oda amade, izimo ezisebenza emaphethelweni amabili naphakathi zihlukile, okuzodala ukuthi imiphetho emibili ye-roller inki igqoke.
Paper Iphepha eliphrintwe kabi, iphepha lempuphu nesihlabathi okuwa ephepheni kuzodala ukuthi i-roller roller neyethusi kugqoke.
⑥ Sebenzisa ithuluzi elibukhali ukudweba imigqa yegeji noma wenze amanye amamaki kupuleti lokuphrinta, okwenza umonakalo ku-roller inki.
⑦ Ngesikhathi senqubo yokuphrinta, ngenxa yezinga eliphansi lamanzi endawo nobulukhuni obuphakeme, futhi ifektri yokuphrinta ayizange ifake amadivayisi afanele okwelashwa kwamanzi, lokhu kuholele ekuqoqeni kokubala ebusweni be-roller roller, okwenyuse ubulukhuni be irabha nokungqubuzana okwandayo. Inkinga ngeke ibangele kuphela ukuthi i-roller roller iphele, kepha futhi izodala nezinkinga ezinkulu zekhwalithi yokuphrinta.
Roller Iroli yokuyinki ibingagcinwanga njalo futhi isetshenziswe kabusha.
⑨ Uma imoto ingagezwa isikhathi eside futhi uyinki ku-roller metering surface nayo izodala ukuhuzuka.
Izinqubo ezikhethekile, njengokuphrinta amakhadibhodi egolide nawesiliva, izitikha noma amafilimu, zidinga ama-inki akhethekile nezithasiselo ezikhethekile, ezizosheshisa ukuqhekeka nokuguga kweroli yenjoloba.
Rough Uburhalarhume bezinhlayiya zikayinki, ikakhulukazi ubukhulu beyinki ye-UV, kunomthelela oqondile ekulimazeni iroli yenjoloba.
Rol Amasondo enjoloba ezingxenyeni ezahlukahlukene agqoka ngokwehlukile ngejubane elihlukile. Isibonelo, iroli yokudlulisa uyinki, ngoba ukunyakaza kwayo kungama-static → isivinini esikhulu → ukubuyisela okuma ndawonye ngokuqhubekayo, izinga layo lokugqoka liyashesha kunokujwayelekile.
⑬ Ngenxa yokuhamba kwe-axial kwe-roller roller no-inki roller, ukuhuzuka kwemikhawulo emibili yeroli yerabha kukhulu kunalokho okuphakathi nendawo.
⑭ Lapho umshini uvaliwe isikhathi eside (njengeholide lomkhosi wasentwasahlobo, njll.), Iroli yerabha icindezelwe ngokwezibalo isikhathi eside, okuholela kububanzi obungalingani bomzimba wenjoloba werabha yenjoloba, nokujikeleza okungalingani kanye ne-extrusion deformation ye-roller yerabha, eqinisa ukuhukululwa kwe-roller yerabha.
Temperature Izinga lokushisa lendawo yokusebenza alilawulwa kahle (kubanda kakhulu noma kushisa kakhulu), okudlula izakhiwo zomzimba zeroli yenjoloba futhi kukhulisa ukuhuzuka kweroli yenjoloba.
