Indlela yokwenza i-anilox rollerumatshini wokuprinta we-flexographic

Uninzi lokushicilela zombini imifanekiso yasemabaleni, emgceni, kunye neyomfanekiso oqhubekayo. Ukuze kuhlangatyezwane neemfuno zeemveliso ezahlukeneyo zokuprinta, abasebenzisi akufuneki bathathe umatshini wokuprinta we-flexo oneeyunithi ezimbalwa zokuprinta ezinee-roller ezimbalwa zokuziqhelanisa. Thatha umatshini wokuprinta we-flexo weyunithi encinci njengomzekelo, okwangoku, ukuqaliswa kwe-6+1, oko kukuthi amaqela emibala ama-6 okuprinta ngemibala emininzi, iyunithi yokugqibela inokuprintwa kunye ne-UV glazing.

Sicebisa ukuba xa kuprintwa kungabi ngaphezu kwemigca eli-150, lo matshini wokuprinta we-flexo ongu-6+1 kufuneka uxhotyiswe ngee-9pcs zee-anilox rollers. Ii-pcs ezine zee-700-line anilox rollers ezinobukhulu obuyi-2.3BCM (1 billion cubic micron/inch) kunye ne-60° zisetyenziselwa ukuprinta umaleko. Ii-3pcs zemigca engama-360 ~ 400, i-BCM6.0, i-60° roller yokuprinta intsimi; ii-2pcs zemigca engama-200, i-BCM15 okanye ngaphezulu, i-60° roller yokuprinta igolide kunye ne-glazing. Ukuba usebenzisa i-oyile yokukhanya esekwe emanzini, kufuneka ukhethe i-360 line roller, ukuze umaleko weoyile ube mncinci kancinci, awuyi kuchaphazela isantya sokuprinta ngenxa yeoyile yokukhanya eyomileyo. I-gloss esekwe emanzini ayinavumba likhethekileyo le-UV gloss. Isixhobo se-anilox roller sinokumiselwa ngovavanyo kunye nothelekiso ngexesha lokuprinta. Ubukhulu bomaleko we-inki obubonwa ngumsebenzisi kwinkqubo yovavanyo buxhomekeke kakhulu kwinani lomgca kunye nexabiso le-BCM le-anilox roller.

I-Anilox roller kwinkqubo yokusebenzisa kufuneka inikele ingqalelo kwiingxaki ezinjani

Apha sithi i-roller yi-laser engraving roller ceramic, isetyenziswa kwiinqwelomoya, kwi-aerospace, kubushushu obuphezulu, kwizinto zokugquma ezichasene nokuguguleka, ngokwe-density ethile, ubunzulu kunye ne-Angle ethile, imilo, kunye ne-laser engraving. Le roller ibonakaliswa yindleko ephezulu, ukumelana nokuguguleka, ukuba isetyenziswa ngokufanelekileyo, ubomi bayo bunokuba yiminyaka eliqela; Ukuba isetyenziswa ngendlela engafanelekanga, ayizukuphela nje ubomi buya kufinyezwa, kodwa kunye ne-roller scrap.

Kwinkqubo yokusetyenziswa, indawo yerola kumatshini wokuprinta ixhomekeke kushicilelo oluthile, ukuprinta okwahlukileyo, indawo yerola nayo yahlukile, ngoko ke ukuprinta kudla ngokuthatha indawo yerola yentambo. Okwangoku, umatshini obanzi obuncinci usetyenziswa kakhulu kwirola yentsimbi eqinileyo, enzima kakhulu, xa ufaka irola ukuze uphephe isigqubuthelo somphezulu werola kwezinye izinto zesinyithi. Ngenxa yokuba i-ceramic coating incinci kakhulu, kulula ukubangela umonakalo osisigxina xa ibetha. Kwinkqubo yokuprinta nokucoca umatshini, i-inki kufuneka ithintelwe kwirola eyomileyo, ukuze kusetyenziswe isepha ekhethekileyo ecetyiswa ngabavelisi be-inki esekwe emanzini, kusetyenziswa ibrashi yentsimbi ukuhlamba, ukuqinisekisa ukucoca okucocekileyo nokucokisekileyo. Kwaye uphuhlise umkhwa wokusebenzisa iglasi ekhulisayo rhoqo ukujonga umngxuma we-rola mesh, xa sele kufunyenwe ukuba i-inki ibekwe ezantsi komngxuma we-mesh kunye nokunyuka kancinci kwendlela, kufuneka icocwe ngexesha. Ukuba le ndlela ingentla ayisebenzi, i-ultrasonic okanye i-sandblasting ingasetyenziselwa unyango, kodwa kufuneka yenziwe phantsi kwesikhokelo sabavelisi berola.

Phantsi kweemeko eziqhelekileyo zokusetyenziswa nokugcinwa, akukho mfuneko yokukhathazeka malunga nokuguguleka kweeroli, iindawo eziphambili zokuguguleka kwenkqubo yokudlulisa i-inki yi-scraper, ngokuchaseneyo, ukuguguleka kwe-roller ceramic coating kunokuthiwa kuncinci. Emva kokuguguleka kancinci kweeroli, umaleko we-inki uya kuba mncinci.

Yintoni ubudlelwane phakathi kwenani lemigca yenethiwekhi yokuprinta kunye nenani lemigca yenethiwekhi yerola

Kumanqaku amaninzi azisa ubuchwepheshe bokuprinta be-flexographic, umlinganiselo wenani lemigca yenethiwekhi yokuprinta kwinani lemigca yenethiwekhi ye-roller umiselwe njenge-1∶3.5 okanye i-1∶4. Ngokusekelwe kumava asebenzayo kunye nohlalutyo lweemveliso ezinikwe yi-American Flexographic Technology Association (FTA) kwiminyaka yakutshanje, umbhali ukholelwa ukuba ixabiso kufuneka libe phezulu, malunga ne-1:4.5 okanye i-1:5, kwaye kwezinye iimveliso zokuprinta ezincinci, umlinganiselo unokuba phezulu nangakumbi. Isizathu kukuba eyona ngxaki inzima ukuyisombulula xa usebenzisa umaleko wokuprinta we-flexographic kukwandiswa kwamachaphaza. Irola enenani eliphezulu lemigca yenethiwekhi iyakhethwa, kwaye umaleko we-inki uncinci. Ukuguquguquka kokwandiswa kwamachaphaza kulula ukulawula. Xa uprinta, ukuba i-inki ayityebanga ngokwaneleyo, ungakhetha i-inki esekelwe emanzini enoxinzelelo lombala ophezulu ukuqinisekisa umgangatho weemveliso zokuprinta.
