Yuav ua li cas kho qhov nro ntawm lub hnab ua tshuab raws li cov khoom siv
Kho qhov nro ntawm lub hnab ua tshuab raws li cov ntaub ntawv sib txawv yog kev ua haujlwm zoo uas sib txuas cov khoom siv, cov cuab yeej ua haujlwm, thiab kev tsim khoom.
Lub hauv paus ntsiab lus yog: Kev nruj tsis zoo dua thaum nws siab dua, tab sis zoo dua thaum nws tsim nyog.
Koj tuaj yeem kho qhov nro raws li cov kauj ruam thiab cov hauv paus ntsiab lus no.
1. Lub hauv paus ntsiab lus: Kho raws li cov yam ntxwv ntawm cov khoom
Lub cev lub cev ntawm cov ntaub ntawv sib txawv (xws li lub zog tensile, modulus ntawm elasticity, thickness) sib txawv heev, yog li ntawd yuav tsum tau customized.
• Cov ntaub ntawv nyuaj (PET, BOPP)
◦ Nta: Zoo rigidity, tsis yooj yim rau ncab lossis deform, tuaj yeem tiv taus qhov nruj heev.
◦ Cov lus qhia: Siv cov kev sib zog siab kom ntseeg tau tias qhov tiaj thiab ruaj khov thaum lub sijhawm ua haujlwm siab -.
• Cov ntaub ntawv mos (PE, CPP, PVC)
◦ Nta: High ductility, mos heev, yooj yim rau ncab thiab ua nyias hauv nro.
◦ Cov lus qhia: Yuav tsum siv cov kev tswj nruj nruj. Kev nruj nruj heev yuav ua rau cov yeeb yaj kiab nqaim thiab nyias nyias, thiab tseem ua rau xoob xoob xws li "pob txha pob txha" tom qab winding.
• Cov ntaub ntawv tshwj xeeb (ultra-thin film, functional film)
◦ Nta: Cov rhiab heev rau kev nro.
◦ Cov lus qhia: Yuav tsum muaj siab -precision, qis- hloov pauv micro- tswj nruj.
2. Cov kauj ruam ua haujlwm: Los ntawm kev xav mus rau kev xyaum
Kauj Ruam 1: Kev kwv yees theoretical thiab siv cov txiaj ntsig zoo
Ua ntej pib, txiav txim siab tus nqi pib raws li kev paub dhau los lossis kev suav yooj yim.
• Empirical method: Teem thawj qhov ntau raws li cov khoom siv thiab thickness.
◦ Piv txwv: PET zaj duab xis feem ntau siv 2-5 kgf nro; PE zaj duab xis siv 1-3 kgf.
• Kev suav cov txheej txheem: Txoj kev xav, nro T yog proportional rau modulus ntawm elasticity E, hla -sectional cheeb tsam A (dav × thickness), thiab elongation.
Formula: T=E \\times A \\times \\Delta L / L .
Qhov no qhia tau hais tias cov yeeb yaj kiab dav thiab tuab dua yuav tsum muaj kev nruj dua.
Kauj Ruam 2: Cov chaw sib txawv hauv cov cheeb tsam sib txawv
Kev nruj tsis zoo ib yam ntawm cov kab ntau lawm. Nws feem ntau ua raws li txoj cai ntawm "pem hauv ntej, siab dua rear" los yog teem sib txawv rau txhua qhov chaw nres tsheb.
1. Unwinding cheeb tsam: Tsawg nro, feem ntau kom kov yeej inertia thiab pub zaj duab xis smoothly.
2. Trailing / processing zone: Cov cheeb tsam tseem ceeb, yuav tsum muaj kev nruj nruj heev raws li qhov kev ntsuas qhov system.
3. Winding cheeb tsam: feem ntau complex. Feem ntau siv taper nro - nro txo thaum yob txoj kab uas hla nce, kom tsis txhob nruj nruj thiab tsis txhob "chrysanthemum qauv" los yog core crushing.
Kauj ruam 3: Dynamic Adjustment and Fine-Tauning
Tom qab pib, kho dynamically raws li qhov tseeb.
• Kho nrog ceev: nce nro thaum lub sij hawm acceleration los tiv thaiv slack; txo thaum lub sij hawm deceleration kom tsis txhob muaj kev ntxhov siab ntau dhau los ntawm inertia.
• Saib zaj duab xis nto:
◦ Wrinkles lossis sagging → nro tsawg dhau → nce kom zoo.
◦ Tshaj- nruj lossis pom tseeb nqaim zaj duab xis → nro siab dhau → txo kom zoo.
3. Cov cuab yeej thiab kev pab: Siv Cov Tswj Kev Nyuaj Siab
Niaj hnub nimno lub hnab ua tshuab feem ntau yog nruab nrog tshwj xeeb nro controllers (magnetic hmoov nres, servo lub cev muaj zog tsav, thiab lwm yam).
• Teem feem pua (%) lossis tus nqi quab yuam tiag tiag (N / kgf) ntawm tus maub los.
• Siv lub luag haujlwm xws li kev teeb tsa taper thiab qhov siab tshaj plaws yob txoj kab uas hla kev teeb tsa rau kev hloov kho tsis siv neeg lub ntsej muag ntse.
4. Cov Lus Cim Tseem Ceeb
• Kho maj mam: Hloov me me txhua zaus, saib cov nyhuv, tom qab ntawd kho ntxiv.
• Tshawb xyuas cov khoom siv kho tshuab: xyuas kom txhua qhov kev taw qhia rollers tig hloov tau yooj yim thiab sib npaug.
• Ib puag ncig: Kub thiab av noo cuam tshuam rau zaj duab xis thiab nro - xyuam xim rau kev hloov ib puag ncig.
