Kev daws teeb meem tsis zoo thiab teeb meem ntawm daim ntawv ntawm Offset Printing Xovxwm
Nyob rau hauv cov txheej txheem ntau lawm, ib tug ruaj khov daim ntawv pub yog ze ze rau lub stability ntawm ntau lawm zoo. Yog tias daim ntawv tsis pub noj zoo, nws tuaj yeem ua rau muaj teeb meem ntau yam, xws li tsis tuaj yeem ua kom lub tshuab ceev, tsis tuaj yeem lav lub peev xwm ntau lawm, thiab tsis tuaj yeem tswj tus number case thiab dej sib npaug, thaum kawg ua rau tsis muaj peev xwm ua kom cov khoom luam tawm zoo.
Qee lub sij hawm dhau los, CD102-5 L tsib- xim Heidelberg daim ntawv pub zaub mov siv los ntawm peb lub tuam txhab tau ntsib cov teeb meem hauv qab no: thaum lub tshuab ceev tshaj 7,000 nplooj ntawv hauv ib teev, cov ntawv tso tawm tau pib skew, uas nyob rau hauv lem tsis tu ncua ua rau misfeeds, tshuab stalls, thiab lwm yam kev ua txhaum, tiv thaiv kom tsis txhob muaj kev sib tw.
Txhawm rau daws qhov txhaum saum toj no, peb xub kuaj xyuas lub sijhawm xa ntawv. Los ntawm nias lub khawm ntawv, peb maj mam nce mus rau 40.3 degree, tom qab ntawd ntxig tus pin xeem rau hauv phab ntsa feeder. Peb pom tias tus pin xeem tuaj yeem dhau los ntawm ob lub cam qhov thiab ntxig rau hauv qhov chaw pub khoom noj (Daim duab 1), qhia tias lub sijhawm xa ntawv tau raug. Tom ntej no, peb tau tshuaj xyuas ib qho - sab kev hloov khoom siv rau daim ntawv pub ceev thiab pom tsis muaj teeb meem. Peb mam li xyuas seb qhov kev xa khoom siab ntawm cov menyuam puas zoo ib yam, thiab tsis muaj teeb meem. Tom qab tig lub tshuab raj, peb pom tias daim ntawv nqus nozzles kuj ua haujlwm synchronously. Txuas ntxiv mus xyuas, peb cia cov cuab yeej pub ntawv tsis tu ncua nyob rau hauv qeeb - khiav hom, thiab tsis muaj teeb meem.
Daim duab 1 Kev txheeb xyuas tus pin hla txoj haujlwm
Peb khiav lub tshuab tsis ua haujlwm dua thiab nias cov ntawv pub rau kom nrawm rau 11,000 nplooj ntawv / teev. Qee lub sij hawm, peb hnov me ntsis vibrations. Tom qab decelerating thiab nres, peb xyuas lub feeder dua thiab thaum kawg pom qhov teeb meem. Thaum tuav ob daim ntawv noj suction nozzles ntawm tes, peb pom me ntsis rau pem hauv ntej thiab rov qab wobble. Kev tshuaj xyuas ntxiv tau qhia tias qhov teeb meem yog nrog cov khoom sib txuas uas txuas cov ntawv pub nozzle pas nrig rau lub pas nrig tsav. Cov khoom no tau pom kev hnav (Daim duab 2), uas tsim qhov sib txawv ntawm tus pas nrig tsav thiab daim ntawv pub lub pas nrig, ua rau lub wobble. Ntawm qhov ceev ceev, lub wobble amplitude yog me me thiab tsis cuam tshuam rau ib txwm ntawv pub, tab sis raws li qhov ceev nce, lub wobble amplitude loj hlob, nws thiaj li cuam tshuam rau cov ntawv pub mis. Qhov teeb meem qhov chaw yog qhia nyob rau hauv daim duab 3.
Daim duab 2 Hnav Cov Khoom Siv
Daim duab 3 Qhov chaw teeb meem
Txhawm rau txheeb xyuas peb qhov kev txiav txim siab, peb siv cov hlua roj hmab los rub ib sab ntawm daim ntawv noj suction nozzle, siv lub elasticity ntawm cov roj hmab band los cuam tshuam qhov cuam tshuam ntawm qhov nqus nozzle qhov tsis sib xws los ntawm kev co. Nyob rau tib lub sijhawm, peb tau nce lub tshuab ceev mus rau 11,000 nplooj ntawv ib teev, thiab cov cuab yeej muaj peev xwm pub tau ntawv zoo.
Tom qab txheeb xyuas qhov teeb meem, peb tau daws nws tam sim ntawd los ntawm kev hloov cov khoom thiab ua tiav cov plua plav tshem tawm thiab kev saib xyuas ntawm tag nrho cov khoom hauv lub taub hau feeder. Thaum kuaj- khiav cov ntawv pub mis, lub tshuab ceev tuaj yeem hloov kho rau 13,000 nplooj ntawv ib teev twg yam tsis muaj teeb meem (Daim duab 4). Nrog rau qhov ntawd, qhov teeb meem tau ua tiav tiav.
