Hauv cov txheej txheem tsim khoom tiag tiag ntawm cov hnab ntim khoom sib xyaw, feem ntau ua tsis tiav vim yog vim li cas los yog lwm yam, xws li kev tsim cov npuas npuas, tsis tshua muaj kev sib xyaw ceev, wrinkling, thiab curling, stretching lossis shrinking, thiab lwm yam. Thaum lub hnab ntim khoom sib xyaw yog curled thiab wrinkled, nws tuaj yeem cuam tshuam rau kev tsim khoom ntawm cov neeg siv khoom thiab ua rau hnyav poob rau cov neeg siv khoom.
1. Qhov tshwm sim ntawm curling thiab wrinkling yog hais txog qhov zoo ntawm nws cov khoom
Ib qho kawg ntawm cov khoom siv sib xyaw lossis luam ntawv substrate yog xoob thiab lwm qhov kawg yog nruj, thiab muaj qhov sib txawv ntawm thickness. Yog tias qhov nruj ntawm ob qhov kawg ntawm zaj duab xis yob sib txawv heev tom qab lub tshuab muab tso rau, zaj duab xis viav vias nce thiab nqis, sab laug thiab sab xis, thiab nws yuav ua rau wrinkles thiab curling, vim tias cov khoom siv thaum nkag mus rau ntawm cov menyuam kub steel thiab Cov menyuam roj hmab kub nias, nws tsis tuaj yeem nyob rau hauv kab rov tav nrog cov kub nias roj hmab cov menyuam, thiab tsis tuaj yeem nias ncaj, ua rau cov khoom tiav tiav rau wrinkle thiab twill, ua rau cov khoom seem;
Thaum cov khoom sib xyaw yog PE lossis CPP, yog tias qhov sib txawv ntawm thickness ntau tshaj 10 feem pua, nws kuj yog ib qho yooj yim rau wrinkle. Lub sijhawm no, qhov nro ntawm cov khoom sib xyaw tuaj yeem tsim nyog nce, thiab nws tuaj yeem raug nyem kab rov tav nrog cov kub-nias roj hmab cov menyuam kom ntau li ntau tau. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias qhov nro yuav tsum yog nruab nrab. Yog tias qhov nro siab dhau lawm, cov khoom sib xyaw yuav raug ncab, ua rau lub hnab lub qhov ncauj curl rau sab hauv. Yog tias qhov sib txawv ntawm cov khoom siv sib xyaw loj dhau, nws tsis tuaj yeem siv.
Vim qhov sib txawv ntawm cov thickness ntawm cov khoom nws tus kheej, cov khoom yog wrinkled thiab curled, yog li cov thickness yuav tsum tau ua tib zoo xyuas ua ntej siv lub tshuab. Thaum nws tshaj 10 feem pua, nws yog qhov zoo tshaj tsis siv nws.
2. Kev ua haujlwm yuam kev kuj ua rau wrinkling thiab curling
Piv txwv li, lub siab ntawm cov kua nplaum kub cov menyuam tsis sib npaug, thiab cov kua nplaum kub cov menyuam tig rov qab thiab tawm thaum lub sijhawm ua haujlwm kom cov khoom sib xyaw tsis tuaj yeem noj tau zoo, ua rau wrinkling thiab curling.
Txoj kev daws teeb meem yog: tshem tawm sab laug thiab sab xis ntawm cov txiv ntoo ntawm cov kua nplaum kub, rov ua kom nruj, thiab siv txawm tias quab yuam. Yog hais tias lub tog raj kheej siab valve kaw lub kub kua nplaum rau cov menyuam, ces koj yuav tsum tau ua tib zoo saib xyuas, thiab koj yuav tsum tau ceev ceev kom tiv tauj cov hlau kub. Thaum kawg ntawm cov menyuam, ntxiv cov cua valve siab thiab thaum kawg nyem nws nyob rau hauv parallel, thiab soj ntsuam lub siab ntsuas tus naj npawb, thiaj li pub cov khoom nyob rau hauv parallel kom txo tau qhov tshwm sim ntawm wrinkling thiab curling tsis ua hauj lwm.
Hauv kev tsim khoom tiag tiag, curling thiab wrinkling kuj muaj feem xyuam rau qhov kub thiab txias ntawm cov hlau yob. Yog hais tias qhov kub ntawm cov yob kub yog siab dhau lawm, qhov tshwm sim ntawm curling kuj yuav nce raws li, tshwj xeeb tshaj yog nyob rau hauv BOPP / CPP thiab BOPP / PE composite lug. Yog tias qhov kub thiab txias dhau lawm, nws tseem yuav ua rau PE zaj duab xis daig los ntawm cov hlau yob thiab khov kho rau cov hlau yob, uas tsis yog tsuas yog siv cov khoom siv khib nyiab xwb tab sis kuj ua rau cov khoom ua tau zoo.
Txoj kev kho mob yog nres lub tshuab thiab tua qhov kub thiab txias ntawm cov hlau yob, thiab tom qab ntawd kho nws tom qab txias. Feem ntau, qhov kub ntawm cov hlau yob yog kho raws li qhov tseeb ib puag ncig thiab kev ua haujlwm, thiab nrog rau qhov dav thiab tuab ntawm cov qauv. Kev tswj kub zoo yuav txo qis qhov ua tsis tiav ntawm curling thiab wrinkling.
3. Qhov tshwm sim ntawm curling muaj ntau yam ua rau kev tswj nruj ntawm kev luam ntawv substrate thiab sib xyaw
Kev tsim tawm ib txwm xav kom lub substrate kom tiaj thiab nruab nrab rau txheej thiab gluing. Qhov nro ntawm cov khoom sib xyaw yuav tsum phim qhov nro ntawm lub substrate. Yog hais tias qhov nro ntawm lub substrate yog siab dhau (coated zaj duab xis) thiab qhov nro ntawm cov khoom sib xyaw me me dhau (cov zaj duab xis sib xyaw), lub hnab tiav yuav dov tawm sab nraud, ua rau lub hnab lub qhov ncauj tsis sib xws. Yog hais tias qhov nro ntawm lub tshuab luam ntawv substrate me me dhau thiab qhov nro ntawm cov khoom sib xyaw loj dhau lawm, lub hnab tiav yuav dov rau sab hauv, ua rau lub hnab ntim tsis zoo, qhov qhib yog warped sab hauv, thiab sealing nyuaj. .
Qhov kev daws teeb meem yog los kho qhov nro ntawm cov ntawv luam ntawv substrate thiab cov khoom sib xyaw los ntawm cov ntawv qhia cov menyuam. Kho qhov nro ntawm lub tshuab luam ntawv substrate los yog cov khoom sib xyaw feem ntau yog ua los ntawm phau ntawv ntsia hlau ntsia hlau los yog los ntawm cov hmoov hlau nplaum sib nqus.
4. Qhov tsis tsim nyog winding nro ntawm cov khoom sib xyaw kuj ua rau lub ntsej muag ntev thiab hlaws.
Yog hais tias qhov nro ntawm rewinding composite cov khoom me me dhau lawm, nrog rau qhov maj mam nce ntawm cov khoom siv rewinding, kab rov tav twill kab yuav tshwm rau hauv qab, ua rau lub hnab tiav tsis sib xws thiab cuam tshuam rau cov tsos. Vim yog cov nyhuv ntawm qhov nro, cov khoom tiav lawm yuav tshwm sim longitudinal wrinkles, tshwj xeeb tshaj yog nyob rau hauv thaum ntxov theem ntawm lub tshuab. Ntawm chav kawm, cov ntawv raj tsis du, thiab winding yog siab thiab qis.
Txoj kev daws teeb meem yog: qhov ceev yuav tsum yog los ntawm qeeb mus rau nrawm thaum pib, lub hom phiaj yog kom qeeb lub zog rub thiab txo qhov tshwm sim ntawm wrinkling, qhov nro yuav tsum yog nruab nrab, sim ua kom qhov pib winding tsis muaj wrinkles thiab tsis dhau xoob, thiab winding nro yuav tsum tau txo tom qab qhov standby ceev yog li qub. Tsis tu ncua, koj tuaj yeem txo txoj hauv kev ntawm wrinkling, feem ntau, cua zog yog flattened los ntawm lub caij nplooj ntoos hlav siab piece los yog sib nqus hmoov nres.
5. Qhov tshwm sim ntawm curling thiab wrinkling tsis ua hauj lwm kuj muaj feem xyuam rau qhov tsis sib xws gluing
Thaum gluing lub substrate, yog tias muaj cov kua nplaum ntau dua ntawm ib sab thiab tsawg dua cov kua nplaum ntawm sab nraud, sab nrog cov kua nplaum ntau yuav inevitably khoov rau sab hauv tom qab ziab, thiab txawm tias lo yuav tshwm sim. Yog hais tias lub gluing system ntawm lub laminating tshuab txiav txim siab lub thickness ntawm cov gluing cov menyuam, sab laug thiab txoj cai tuav tuav yuav tsum tau kho kom lub gluing txawm; los yog kho tom qab.
Txoj hauv kev zoo tshaj plaws los ntsuas seb lub gluing zoo li cas yog nias lub kaw lus gluing nrog rau sab laug thiab sab xis ntiv tes txhawm rau saib nws cov tuab thiab thaum kawg ua rau gluing tusyees, uas yuav txo tau qhov tshwm sim ntawm curling thiab wrinkling.
6. Hemming, wrinkling, thiab compounding muaj feem xyuam rau kev huv si ntawm cov traction rollers ntawm txhua phau ntawv qhia cov menyuam
Thaum lub sij hawm ua hauj lwm ntawm lub substrate, yog hais tias tus traction roller yog qias neeg los yog nto tsis sib xws, nws yuav yooj yim ua rau oblique wrinkles. Txoj kev zoo tshaj plaws nyob rau lub sijhawm no yog siv cov ntawv xov xwm los txiav 10cm ntev thiab 6cm dav rau shimming. Vim yog inertia, cov ntawv xov xwm yuav synchronize nrog traction roller. Tig, kom lub twill phenomenon yuav daws tau.
7. Mechanical tsis ua hauj lwm muaj feem xyuam rau wrinkling tom qab compounding
Lub tshuab tsis ua haujlwm ntawm lub tshuab laminating ua rau qhov nro ntawm lub substrate tsis tuaj yeem tswj tau, loj dhau los yog me me dhau los ua kom yooj yim pub rau hauv cov hlau kub yob, uas yuav ua rau wrinkles thiab curling ntawm qhov winding. Tom qab ua tib zoo tshuaj xyuas, muaj ob lub ntsiab lus. taw tes:
Txawm tias qhov sib nqus hmoov nres yog tawm ntawm qhov sib npaug thiab qhov nro yog qhov loj thiab me, uas tswj tsis tau; los yog lub rhiab heev ntawm lub sensor yog distorted, thiab lub speeds ntawm lub pem hauv ntej thiab rear motors tsis ua hauj lwm, uas ua rau cov saum toj no tshwm sim. Thaum kawg, nws pom tias lub sensor yog distorted. Lub nro yog tswj thiab qhov txhaum raug tshem tawm.
8. Mos ntim wrinkling muab faib ua composite wrinkling thiab winding wrinkling
Composite wrinkling yog tias ib lub hauv paus cov ntaub ntawv yog tiaj tus thiab lwm cov ntaub ntawv hauv paus protrudes los tsim ib txoj kab rov tav lossis ntsug. Ob txheej ntawm cov khoom siv hauv paus yog sib cais los ntawm ib leeg, thiab ob txheej ntawm lub qhov txhab thiab wrinkled puag cov ntaub ntawv tseem sib txuas ua ke, tab sis Vim yog extrusion ntawm sab nraud quab yuam, nto ntawm cov zaj duab xis sib xyaw nthuav tawm wavy wrinkles, uas yog. feem ntau nws yuav ua rau winding wrinkles ze ntawm lub hauv paus.
Feem ntau yog vim li cas ntawm composite wrinkling yog:
Thawj tack ntawm cov nplaum nws tus kheej tsis txaus;
Siab hnyav residue;
Tus nqi ntawm cov kua nplaum siv yog siab lossis qis;
Qhov nro ntawm cov khoom sib xyaw substrate tsis sib xws;
Cov huab cua ntim ntawm qhov cub loj heev;
Lub winding nro yog me heev;
Lub flatness ntawm lub substrate tsis zoo.
Lub wrinkling nyob rau hauv winding feem ntau yog vim tsis zoo tswj ntawm nro nyob rau hauv lub composite winding txheej txheem. Tom qab winding, sab nraud yog nruj thiab sab hauv yog xoob, thiab qhov sib txawv ntawm cov khaubncaws sab nraud povtseg yog loj, muab qhov chaw rau shrinkage.
