Qhov txiaj ntsig tseem ceeb ntawm lub tshuab tsis yog -stretch lub hnab ua tshuab (tseem hu ua xoom- lub hnab ntim ua tshuab) yog nyob rau hauv nws lub peev xwm los txo cov zaj duab xis ncab thaum lub sijhawm ua haujlwm thiab sib khi. Qhov no ua rau nws tshwj xeeb tshaj yog tsim los tsim cov hnab tuab, hnyav - lub hnab ua haujlwm, thiab cov hnab yas uas xav tau cov qauv siab rau kev foob thiab lub zog.
Txhawm rau ua haujlwm cov cuab yeej no kom zoo thiab ua kom cov khoom zoo, ntawm no yog cov ntsiab lus tseem ceeb uas koj yuav tsum tsom mus rau:
Parameters & Kho
Cov riam sib khi thiab lub tshuab ua kom txias yog lub plawv ntawm lub tshuab uas tsis yog - ncab lub hnab ua tshuab, ua qhov kev ntsuas qhov ntsuas qhov tseem ceeb:
1.Fine-tuning Sealing Riam Parameters: Yuav kom ua tiav lub foob muaj zog thiab zoo huv si, koj yuav tsum teem lub sijhawm nyob hauv qhov chaw qis (lub sijhawm sib khi) thiab lub sijhawm nyob ntawm qhov chaw sab saud (lub sijhawm txias) raws li lub hnab tuab. Tso cai rau lub foob kom txias tag ua ntej pub cov khoom zoo tiv thaiv deformation los ntawm stretching.
2.Synchronous Sealing & Separation: Siab- zoo tsis yog -stretch machine feem ntau muaj cov khoom siv rau cov cua sov synchronous, synchronous sealing siab, thiab synchronous sib cais. Qhov kev tsim no ua kom ntseeg tau tias thaum sealing cov ntaub ntawv tuab (piv txwv li, ib txheej tshaj 150 microns), cov kab foob tseem tsis tau ncab, thiab cov khoom yuav tsis lo rau lub sealing puag thaum pub mis, yog li tiv thaiv cov khoom tawg.
3.Temperature & Pressure Settings: Teem lub tshav kub sealing (piv txwv li, feem ntau ntawm 120-150℃rau PE zaj duab xis) thiab sealing siab kom tsim nyog raws li cov khoom siv zaj duab xis tshwj xeeb (xws li PE, PP, thiab lwm yam).
Kev Ua Haujlwm Txhua Hnub & Kev Tu
Cov txheej txheem kev ua haujlwm tau zoo thiab kev saib xyuas tsis tu ncua tuaj yeem txuas ntxiv lub tshuab lub neej thiab txo qhov tsis xws luag:
1.Pre-kev tshuaj xyuas pib: Ua kom lub zog ruaj khov, txhim khu kev qha hauv av, xyuas tias huab cua qhov siab ua tau raws li cov qauv (feem ntau yog 0.6-0.8 MPa), thiab xyuas kom meej tias lub khawm nres thaum muaj xwm txheej ceev.
2.Film Tension Control: Thaum txhim kho zaj duab xis yob, nco ntsoov kho qhov nro los ntawm kev tswj qhov nro. Tsis sib xws los yog misaligned qhia rollers tau yooj yim ua rau zaj duab xis deviate los yog wrinkle thaum ua haujlwm.
3. Photoelectric Tracking Calibration: Tsis tu ncua ntxuav lub lens ntawm lub qhov muag photoelectric (xim cim sensor) kom paub tseeb tias nws raug taug qab cov xim cim ntawm cov ntawv luam tawm, lav qhov tseeb ntawm lub hnab ntev thiab txiav txoj haujlwm.
4.Regular Cleaning & Lubrication: Tom qab txhua hnub ua hauj lwm, huv si huv si residual zaj duab xis thiab carbon deposits los ntawm tshav kub sealing riam thiab cutter kom tsis txhob muaj kev cuam tshuam lub foob zoo. Tshawb xyuas cutter sharpness txhua lub lim tiam, thiab lubricate kis tau tus mob chains, bearings, thiab lwm yam khoom txhua hli.
