Digitally ua ntej- cov ntaub ntawv luam tawm ua rau lub web slippage thiab lateral tracking yuam kev ntawm siab -ceev corrugators vim cov inks thiab overprint varnishes (OPV) drastic txo cov ntawv coefficient ntawm kev sib txhuam (COF). Standard steel feed rollers poob traction tiv thaiv lub polymer du nto, ua rau misaligned boards thiab sau npe yuam kev ntawm kev txiav -tawm riam. Kev tshem tawm cov teeb meem kev taug qab no yuav tsum tau muaj plaub qhov kev hloov kho tshwj xeeb: hloov lub zeb yob sawv ntsug rau lub tshuab kaw tsis siv neeg kaw- voj nro tswj, txo ua ntej- rhaub qhwv lub kaum sab xis kom tiv thaiv thermal ink softening, retrofitting tsav rollers nrog siab- tuav polyurethane coatings, thiab siv dual{{8} hneev taw kom qhuav{9} channel caum.
Kev sib koom ua ke ntawm kev lag luam digital luam ntawv rau hauv cov khoom ntim ntim khoom ua haujlwm tau hloov pauv luv luv -khiav tshuaj pleev ib ce, hluav taws xob, thiab e- lub thawv xa khoom lag luam. Los ntawm kev siv siab - ceev digital presses los luam tawm vivid, ntau - xim duab ncaj qha mus rau yob ntawm linerboardua ntejlawv mus txog lub corrugator- cov txheej txheem hu ua digital pre-print-box cov nroj tsuag tuaj yeem hla tus nqi kim, qeeb txheej txheem ntawm litho-lamination.
Txawm li cas los xij, nqa cov digitally ua ntej - luam tawm yob mus rau qhov siab - kab nrawm nrawm qhia txog qhov teeb meem tseem ceeb:web slippage thiab taug qab kev sib raug zoo yuam kev.
Thaum lub sij hawm tus txheej txheem corrugator khiav, cov ntawv nyoos cia siab rau qhov kev sib tw ntawm kev sib txhuam kom txav tau yooj yim los ntawm cov yob sawv ntsug, ua ntej- cua sov, ib lub ntsej muag, thiab ob lub nraub qaum. Cov inks digital thiab lawv cov tiv thaiv saum toj kawg nkaus -coat varnishes hloov pauv cov txheej txheem saum npoo av. Thaum lub tshuab luam ntawv yob khiav ntawm kev lag luam siab, nws nquag plam tawm tsam pub cov menyuam thiab rub tawm ntawm kev sib tw. Qhov no tsim warped boards, ruined print graphics, thiab loj txiav yuam kev ntawm lub teb riam.
Kev daws qhov kev sib tw no hybrid- era kev sib tw yuav tsum tau nkag siab txog cov kev hloov kho tshuab thiab tshuaj lom neeg tshwj xeeb uas yuav tsum tau ua kom ua ntej - cov ntawv luam tawm taug qab ncaj nraim.
1. Kev Tshawb Fawb Txog Kev Tshawb Fawb: Vim li cas Cov Inks ua rau plam
Lub hauv paus ua rau lub vev xaib slippage yog qhov poob qis hauv daim ntawvCoefficient ntawm kev sib txhuam (COF)thiab lub zog nto, uas ntsuas hauv millinewtons ib 'meter' (mN / m) lossis dynes.
Standard, unprinted kraft linerboard nta ib tug ntxeem tau, fibrous nto uas muab zoo heev mechanical tuav rau steel thiab roj hmab rub rollers. Thaum cov inkjet inks (txawm tias dej-raws li cov xim pleev xim los yog UV- cov tshuaj kho tau) raug siv, lawv ua rau cov dej ntws tawm, tsim kom muaj cov yas du, zoo li polymer zaj duab xis saum daim ntawv.
Txhawm rau tiv thaiv qhov siab - daws teeb meem cov duab los ntawm khawb thaum lawv hla cov phaj kub ntawm lub corrugator, cov tshuab luam ntawv digital feem ntau siv cov kua roj vanish (OPV). Cov kua roj vanish tiv thaiv no ua zoo li lub roj nplua nyeem ntawm cov kab corrugator.
- Traditional Linerboard COF:Kev sib txhuam siab, muab cov neeg kho tshuab muaj zog traction.
- Digitally Pre-Printed Liner COF:Tsis tshua muaj kev sib txhuam, ua rau traction poob raws li tus qauv ntawm cov menyuam nro.
Vim tias lub ntsej muag luam tawm ntawm lub liner tau txo qis traction, tus qauv rub - cov menyuam clamping siab tsis txaus lawm. Thaum lub corrugator nrawm nrawm dua150 meters ib feeb, tus tsav rollers tig nrawm dua li daim ntawv slick web tuaj yeem taug kev. Qhov kev tsis sib haum no ua rau lub cev swb (slip), ua rau lub vev xaib mus rau tom qab thiab tsim cov teeb meem tseem ceeb ntawm kev taug qab.
2. Kev ntub dej -Kev Kho Kom Kawg: Tswj Kev Nyuaj Siab thiab Kev Kub Kub Softening
Kev txhim kho qhov yuam kev yog pib ntawm qhov ntub dej - kawg ntawm lub corrugator, tshwj xeeb tshaj yog nyob rau ntawm lub zeb yob sawv ntsug thiab ua ntej - lub tshuab cua sov. Ib txwm neeg teb xov tooj instincts hais kom nruj cov neeg kho tshuab nres ntawm lub yob sawv yog tias lub vev xaib pib mus. Txawm li cas los xij, nrog qis -kev sib txhuam ua ntej- cov ntawv luam tawm, kev siv tshuab ntau dhau yuav ua rau cov traction ntawm koj cov rolls tam sim ntawd, ua rau cov khauj khaum hnyav dua thiab muaj feem cuam tshuam rau lub vev xaib.
Siv Kaw -Loop Tension Control
Hloov ntawm phau ntawv qhia kev siv lub tshuab braking, ua ntej- cov ntaub ntawv luam tawm yuav tsum tau siv lub tshuab ua haujlwm, kaw- lub voj nro uas siv ultra- cov khoom siv ceev ceev. Lub load hlwb tsis tu ncua saib xyuas cov feeb hloov hauv lub vev xaib nruj raws li cov yob txoj kab uas hla shrinks.
Kev nyab xeeb PLC yuav tsum hloov kho lub zog ntawm lub zog kom ceev nrooj hauv qhov nqaim, qis - qhov rai cuam tshuam. Lub hom phiaj yog kom tswj tau kom txaus txaus kom tsis txhob muaj lub hnab ntim khoom tsis muaj overloading kev sib txhuam ntawm cov khoom noj.
Modulating Pre-Heater Wrap Angles
Kev tswj qhov kub thiab txias yog lwm qhov sib txawv tseem ceeb. Digital inks thiab varnishes soften thaum raug thermal loads heev. Yog tias lub tshuab ua ntej - cov ntawv luam tawm qhwv tob dhau ib puag ncig tus qauv ua ntej- lub tshuab rhaub cua sov, cov cua kub uas muaj zog tuaj yeem ncav cuag qhov chaw uas cov txheej number case ua tacky lossis "gummy."
Thaum tus cwj mem softened no ntaus cov snubber yob los yog lub siab yob ntawm ib lub ntsej muag, nws tsim erratic, siab -kev sib txhuam ib cheeb tsam. Qhov kev sib txuas hauv cheeb tsam no, sib hloov nrog cov ntu ntawm qis - kev sib txhuam ntog, ua rau lub vev xaib jerk rau sab, pov tawm ntawm kev taug qab sab nraud.
Engineering Txoj Cai ntawm Thumb:Thaum khiav digitally ua ntej- luam tawm webs, txo lub pre-heater qhwv lub kaum sab xis los ntawm30% mus rau 50%piv rau cov ntaub ntawv uas tsis tau luam tawm, tso siab rau ntawm cov dej noo- ntsuas cov chav da dej kom txias rau daim ntawv yam tsis muaj cua sov ntawm tus cwj mem polymer matrix.
3. Qhuav-End Synchronization: Sensor Calibration thiab Riam Chasing
Txawm hais tias lub vev xaib luam tawm tau zoo dhau los ntawm ob lub backer yam tsis muaj drifting, slippage tuaj yeem ua rau muaj kev puas tsuaj loj thib ob ntawm qhov kev txiav rotary -tawm riam thiab computerized slitter scorer.
Txhawm rau txiav cov nplooj ntawv corrugated kom meej meej ntawm cov duab luam tawm, qhov qhuav -kawg lub khoos phis tawj tso siab rau siab- cov ntawv sau npe kho qhov muag ceev (feem ntau hu ua "qhov muag cim" lossis "cov cim hla") luam tawm raws ntug ntawm lub liner. Ib qho optical register sensor nyeem cov cim no thaum lawv ya dhau los, qhia cov riam tig raws nraim thaum yuav hlais.
Yog hais tias lub rooj sib txoos ua ke muaj kev cuam tshuam me me, cuam tshuam tsis sib xws ntawm lub ntsiab conveyor siv, cov cim qhov muag yuav hla lub qhov muag pom ntawm qhov tsis sib xws, tsis muaj kev cia siab. Tus txiav -tawm tswj yuav pom qhov no yog qhov yuam kev ceev thiab nkag mus rau lub xeev hu ua"hnav caum."Cov riam teb yuav txuas ntxiv nrawm thiab qeeb hauv qhov kev xav ua kom ua raws li qhov kev nyeem ntawv tsis zoo, uas ua rau tawm - ntawm -square boards, qhov ntev ntawm daim ntawv tsis sib xws, thiab cov khoom seem loj heev.
Txoj Cai Kho Kom Zoo Rau Riam Chasing:
- Dual{0}}Channel Encoder Synchronization:Tsis txhob cia siab ib leeg rau lub log encoder caij rau ntawm daim ntawv nplaum. Ua ke ib tug thib ob encoder ncaj qha txuas mus rau lub ntsiab tsav lub cev muaj zog ncej. Cov tswj software yuav tsum sib piv ob lub cim; Yog tias pom muaj qhov sib txawv, nws qhia tau tias daim ntawv hlais, tso cai rau PLC siv cov txheej txheem dampening es tsis dhau - kho cov riam ceev.
- Contrast thiab Xim -Spectrum Sensor Tuning:Digital inks pom lub teeb txawv dua li cov ntawv nyoos kraft. Txheem xim liab- lub teeb pom kev zoo feem ntau nyuaj los nyeem cov ntawv sau npe luam tawm ntawm cov keeb kwm yav dhau los tsaus nti lossis coated hauv siab -gloss varnish. Hloov kho mus rau ntau-spectrum RGB lossis xiav- lub teeb pom kev sib txawv, uas muaj kev nkag siab ntau dua rau cov txheej txheem sib txawv, tshem tawm cov lus tsis tseeb - nco cov cim.
4. Kev hloov kho tshuab rau qis-Txoj kab sib txhuam
Yog tias koj cov nroj tsuag npaj yuav khiav digitally ua ntej - cov ntaub ntawv luam tawm ua ib feem ntawm nws cov khoom sib xyaw, kev cia siab rau kev hloov kho software nkaus xwb yog kev kho ib ntus. Kev mus tas li, txhim khu kev qha yuav tsum tau kho dua tshiab cov ntsiab lus ntawm kev sib cuag ntawm cov kab corrugator.
Hloov Knurled Steel nrog Polyurethane Txheej
Traditional corrugator feed rolls siv knurled lossis checkered steel nto los tuav cov ntawv nyoos. Thaum cov hlau ntse no nias tawm tsam cov ntawv luam tawm digitally, lawv tsis tuaj yeem tom rau hauv cov ntawv nplaum nplaum zoo, thiab lawv muaj kev pheej hmoo khawb lossis khawb tawm ntawm cov duab zoo nkauj.
Hloov cov hard steel rolls nrog siab -durometerpolyurethane-coated rollers. Polyurethane deforms microscopically nyob rau hauv siab, ua rau qhov tseeb saum npoo ntawm kev sib cuag tiv thaiv cov slick varnish txheej thiab maximizing kev sib txhuam yam tsis muaj kev puas tsuaj rau cov luam ntawv zoo.
Nqus -Pull Tables
Ntawm qhov tawm ntawm ob sab nraub qaum, lub rooj sib koom ua ke yog ib txwm rub los ntawm cov hlua khi hnyav hnyav nias los ntawm saum toj. Yog hais tias lub hauv qab liner yog hnyav varnished thiab luam tawm, nws yuav swb hla cov hlau bedplates hauv qab no.
Txhim kho anqus tsev - pab rub roojdaws qhov no los ntawm kev siv lub tshuab nqus tsev tswj los ntawm lub matrix ntawm cov slots hauv qab txaj. Qhov kev nqus dej no rub lub rooj tsavxwm txav kom ruaj khov rau qhov siab - tuav txoj siv thauj khoom qis, kom ntseeg tau tias muaj qhov zoo ntawm lub tshuab xauv uas tshem tawm tag nrho qhuav - kawg slippage.
