Ua ntej, kev sib raug zoo ntawm kev sib raug zoo thiab lub sijhawm
Daim ntawv mus dhau ntawm kev hloov cov txheej txheem los ntawm yoov mus rau lub rooj noj mov. Kev hloov mus rau lwm qhov yog hais txog lub sijhawm thiab txoj haujlwm kev sib raug zoo thaum daim ntawv tso ntawm ib lub tshuab mus rau lwm tus. Lub sij hawm kev sib raug zoo no kuj yog hu ua kev sib raug zoo ntawm kev ua neej, uas yog hais txog qhov uas tau hloov. Qhov kev sib raug zoo ntawm tus txheeb ze ntawm qhov taw, yog li lub sij hawm sib raug zoo ntawm feem kaum, thiab ib lub voj voog yog 360 °. Yuav kom ntsuas thiab lub sij hawm kev sib raug zoo ntawm lub Cheeb Tsam, ib qho 360 ° kawm tiav disk yog feem ntau txuas nrog lub ntsej muag kawg ntawm lub tog raj kheej ntawm qhov offset xovxwm. Piv txwv li: J2108, J2205 lub tswv yim kheej kheej, thawj daim ntawv pub rau cov ntsej muag kawg ntawm lub tshuab uas muaj ntau lub tshuab yog feem ntau muaj kev sib tham.
Nyob rau hauv lub tshuab luam ntawv tshuab luam ntawv, muaj qee qhov kev sib raug zoo ntawm qhov txav ntawm qhov qub zog. Muaj ntau lub sij hawm txav ntawm lub tshuab tsis hloov kho, tsuas yog ib qho me me ntawm lub sij hawm txav ntawm lub tshuab yog kho tau, thiab kev hloov kho tseem ceeb tshaj plaws. Muaj: lub sij hawm qhib thiab kaw cov ntawv ntawm daim ntawv, lub sij hawm muab tus me nyuam lub sij hawm, lub sij hawm ntawm kev sib tw hauv ntej, lub sij hawm txav ntawm kev sib tsoo, thiab lub sij hawm txav ntawm tus neeg pub mis.
Lub sij hawm kev sib raug zoo yog ib qho tseem ceeb ntawm kev lag luam luam ntawv. Lub sij hawm kev sib raug zoo tsis yog. Qhov teeb meem loj tshaj plaws yuav ua rau cov khoom sib tsoo, tsoo thiab ua kom lub tshuab puas tsuaj. Lub sij hawm kev sib raug zoo yog feem ntau rau cov ntawv tso, Feida paper feeding, thiab qhov hloov ntawm daim ntawv ntawm cov hniav. Cov teeb meem uas tshwm sim los ntawm lub sij hawm tsis zoo yog: overprinting, ghosting, xa ntawv, poob ntawv hauv nruab nrab, Feida paper feeding failure, lwm yam. Yog li, nws tseem ceeb heev kom siv tau thiab kho lub sij hawm ntawm qhov offset xovxwm.
Thib ob, txoj kev sib raug lub sijhawm tseem ceeb thiab kev xav tau
1. Feida kev sib raug zoo
Feida lub sij hawm muaj kev sib raug zoo nrog rau lub sij hawm kev sib raug zoo ntawm qhov kev sib koom ntawm ko taw thiab kev sib txuas ntawm daim ntawv no, lub sij hawm kev sib raug zoo ntawm cov ntawv sib cais no thiab cov ntawv xov no, lub sij hawm kev sib raug zoo ntawm daim ntawv pub tsis muaj dej thiab hauv ntawv nres, nozzle thiab daim ntawv qhia cov sij hawm rau cov menyuam. Kev sib raug zoo, thiab lwm yam., Tsuas yog lub sijhawm ua ntej ntawm kev nres tsheb thiab daim ntawv qhia phau ntawv log yog kho tau, thiab lub sij hawm txav ntawm lwm qhov tsis raug kho.
Lub tshuab tseem ceeb yuav tsum ua raws li nram qab no: 1 Thaum lub npog qhov ncauj tsis so, daim ntawv no yuav tsum txav mus rau qhov taw qhia qis thiab pib nqus tau. 2 Thaum qhov kev sib txuas no tsis txav mus rau qhov siab tshaj plaws, lub taub ntim hauv siab tuaj yeem raug ntaus. Daim npav 3-tsho thiab daim ntawv no yuav tsum tau muab daim ntawv ntsaws ua ke (2 ° txog 5 °). Tom qab 4 feeb ntawm daim ntawv xuas tshuab raj no nres (2 ° yuav tsum dhau los), daim ntawv no tau xa tuaj.
Thaum lub hnab 5 daim ntaub ntawv tso rau ntawm daim ntawv, daim ntawv pub no tau muab xa tuaj thiab lub taub txau yuav tsum pib dua daim ntawv nres ua ntej ntawv txiav. 6 Tom qab daim ntawv qhia cov tub ntxhais kawm ntawv tuav cov ntawv, daim ntawv pub mov tuaj yeem muab ntawv. Thaum lub tshuab laus laus thiab cov ntawv xa mus ceev ceev qis dua daim ntawv pub ntawm daim ntawv qhia rau cov menyuam kawm ntawv, daim ntawv pub no yuav tsum muab tso rau hauv daim ntawv, thiab tom qab ntawd daim ntawv qhia rau cov menyuam ntawv yuav tsum txuas nrog daim ntawv.
Feida cov teeb meem loj hauv kev sib raug zoo yog raws li nram no: 1 Lub taub txau feem ntau nias ntawm daim ntawv los ua ib daim ntawv tsis ua haujlwm. Thaum cov nqus ntawm qhov kev sib cais no tsis tshua muaj me me, qhov sib cais no yog siab dhau los ntawm daim ntawv los yog cov yeeb ncuab nyhav ntxig thaum ntxov, daim ntawv tshwm sim ntawm lub tsho ntawm lub tshuab ntiv taw tawm ntawm kev sib cais no yuav tshwm sim, thiab qhov tshwm sim feem ntau yog npliag. Yog tias pom tau tias qhov kev nias ntawm lub cuj pliav yog ntxov dhau los, lub sij hawm nias ntawm lub cuj pliav tuaj yeem ua raws li qeeb qeeb, feem ntau ntawm 5 ° qeeb qeeb los txhim kho qhov kev cia siab ntawm daim ntawv sib cais. Txawm li cas los xij, lub tsho hauv qab yuav tsum tau ua kom pom tseeb tias lub taub taw ntawm cov kauj khawm cam yog txuas nrog lub taub hau ua ntej daim ntawv yog nqus los ntawm lub taub txau. Ua kom kho, tshem lub hau thiab tig lub raj kom rov ua zoo dua tus pin lub qhov los yog siv lub hau ntsia hlau. tsau. 2 Muab cov cua ntses ntawm cov cua ntsawj los ntawm cov ntaub ntawv tshauv thiab daim ntawv cov plaub hau, ua rau kev hloov ntawm lub nqus pa yuav tshwm sim, thiab cov ntawv xov tsis tau muab coj los ua tsis tau lawm, thiab daim ntawv txiav tawm tsis tau tawm los yog daim ntawv feeder tau xa tuaj. Daim ntawv tshwm sim. Feem ntau, tev taus yuav muab tshem tawm thiab ntxuav. 3 Kev cob qhia rau tus kheej los yog daim ntawv txiav thiab lwm cov sijhawm ntawm lub sijhawm ua haujlwm tsis haum, feem ntau hloov cov ntawv qhia rau cov menyuam kawm ntawv los yog daim ntawv txiav plaub, nws yuav yooj yim dua.
4 J2108 thiab lwm yam qaum teb offset luam ntawv tshuab xoob npuaj tshuab raj no hauv daim ntawv suction nozzle thaum daim ntawv tsis tshuab, feem ntau ua rau tshuab los tshuab los tshwm, ua rau tsis muaj chaw seem, ob zaug tsis ua. Txhim kho lub voj voog cua kom daws tau. Ntxiv nrog rau qhov no, muaj lwm yam teeb meem nrog kev txom nyem kev sib raug zoo, uas yog lub ntsiab tseem ceeb rau qhov tsis txaus siab ntawm daim ntawv pub nyob rau hauv Beiren offset presses.
2, muab qhov khoom tso rau hauv lub sij hawm
Kev ua haujlwm ntawm qhov tuav twj yog kom khov daim ntawv los ntawm daim ntawv noj khoom noj thiab txav nws qhov chaw. Lub sij hawm kev sib raug zoo ntawm qhov muab ntaus ntawv ncaj qha cuam tshuam cov ntawv kawm qhov kev ua tau zoo, uas yog qhov tseem ceeb rau daim ntawv thiab lub tes tsho tes. Lub sijhawm kev sib raug zoo yog:
Daim ntawv ncig ntawm thaj chaw ncig (t thij), daim ntawv qhia lub sijhawm (t-axis)
t lub lis piam == t ua ntej -t | | t yog lub sij hawm thaum lub ntsuas pa hauv pem hauv ntej tau mus txog ntawm qhov chaw nres tsheb, t yog rub lub koob siv ntawv rub tawm xwb.
T axis = | t pull -t cia t tuas rub tawm ntsuas xwb cia cia ntawv sij hawm
Feem ntau, lub t-lub lim tiam ntau dua 40 ° kom paub meej qhov zoo ntawm qhov zoo ntawm qhov ntawv, thiab qhov kev tshaj tawm yog qhov tseeb. Lub t-axis yuav tsum siab tshaj 40 ° kom paub tseeb zoo qhov chaw ntawm daim ntawv thiab ua zoo tshaj qhov qub. Txawm li cas los xij, raws li kev luam ntawv nce siab, lub sij hawm tseem ceeb ntawm lub t-lub lim tiam thiab lub t-axis yog raug txo, thiab qhov kev ua tau zoo ntawm daim ntawv yog degraded, yog li hais tias lub irregularity ntawm lub tes tsho yog puav tau tsim.
Cov lus nug nquag nug txog lub sijhawm teem rau ntawm qhov khoom siv: 1t axis loj heev, t lub sijhawm tsawg heev, txawm tias thaum daim ntawv cia li mus rau hauv ntej qhov ntsuas pa, rub lub ntsuas pa pib rub tawm ntawv. Lawm, kev ntsuas yog cov neeg txom nyem heev. Txoj kev daws teeb meem feem ntau yog kho lub plab tag nrho. Daim ntawv rub tawm ntev (t-axis) thiab rub lub ntsuas pa cia li cia lub sij hawm ntawv (t cia) ua ntej kho lub t-axis = 40 °, thiab tom qab ntawd ces kho t cia rau daim ntawv txiav hniav.
2 Daim ntawv tsis haum rau lub sijhawm ua ntej kev cai. Feem ntau, thaum lub hauv ntej qhov ntsuas tag nrho mus txog ntawm qhov chaw ntawm daim ntawv nres, daim ntawv yuav tsum yog 6 ~ 10 hli deb ntawm kev ntsuas (pem taub hau ntej). Yog tias nws yog ntxov dhau, daim ntawv yooj yim heev dhau los, thiab daim ntawv lig dhau heev lawm, xws li lig dhau lawm, daim ntawv Lub sij hawm ncig ntawm qhov chaw tsis txaus, thiab nws yooj yim los ua daim ntawv tsis tiav. Qhov kev daws teeb meem yog los kho lub sij hawm ntawm cov kev cai ua ntej thiab Feida.
