Txoj kev sealing ntawm polypropylene zaj duab xis ntawv khob ntim tshuab feem ntau yog siv cov thev naus laus zis sealing thiab ua ke nrog kev tswj tsis siv neeg kom ua tiav sealing zoo. Cov yam ntxwv tshwj xeeb thiab cov txheej txheem siv yog raws li hauv qab no:
I.Core Sealing Technology: Thermal Pressure Sealing Principple
Lub foob yog tsim los ntawm cua sov PP zaj duab xis rau lub xeev molten siv cov khoom siv cua sov cua sov, xws li hluav taws xob cua sov phaj, cov menyuam los yog cov khoom siv hluav taws xob siab, thiab tom qab ntawd siv cov tshuab ua kom lub zog rau cov txheej txheem ua ke. Cov khoom siv polypropylene tuaj yeem softened thiab sib txuas sai sai tom qab cua sov, solidified thiab tuav sealable tom qab txias vim nws zoo heev thermoplastic zog.
Nws yog ib daim ntawv uas muaj cua sov.
Phaj- hom cua sov sealing: Phaj Thermal Seal Direct Pressure Film, haum rau polyethylene thiab polypropylene composite zaj duab xis, qauv yooj yim thiab ceev sealing ceev.
Cov Menyuam Kub Foob: Ib khub ntawm cov cua kub chais txuas txuas ntxiv dov zaj duab xis, haum rau siab - ceev ntau lawm kab, xws li ntawv khob paj kws ntim tshuab.
Lub nplhaib hom cua sov foob: Nplhaib hom cua sov foob sandwiched ntawm txav lub nplhaib hom steel siv, cov cua sov thaiv hauv cov hlua hlau muab cua sov, thaum txias thaiv cov ntaub ntawv foob, haum rau polypropylene zaj duab xis uas muaj thermal deformation.
Pulse heat sealing: Ib qho nickel-chromium alloy strip luv luv hluav taws xob, ua rau kub kub uas yaj thiab khi cov zaj duab xis, khov thiab tso tawm, haum rau cov xwm txheej uas xav tau lub zog sealing siab (xws li ntim kua).
II. Tsis siv neeg tswj thiab Sealing Accuracy PLC tswj qhov system
Cov ntawv niaj hnub- khob ntim tshuab (xws li ntawv- khob paj kws ntim tshuab) siv ntau lub tshuab PLC tswj. Qhov ntsuas kub, siab, ceev thiab lwm yam tsis tuaj yeem teeb tsa los ntawm lub vijtsam kov kom ntseeg tau qhov sib xws ntawm lub foob. Piv txwv li:
Kev tswj qhov kub thiab txias: cov yeeb yaj kiab polypropylene feem ntau raug kaw ntawm qhov kub ntawm 160 thiab 180 degrees Celsius. PLC tuaj yeem tswj xyuas qhov ntsuas kub ntawm cov cua sov thaiv kom tsis txhob muaj cov yeeb yaj kiab los ntawm kev cog lus lossis gelatinizing vim overheating.
Kev hloov siab: Lub tshuab pneumatic muab lub siab ruaj khov (xws li . 0.65-1.2 Mpa) kom ntseeg tau tias lub zog sealing thiab tiv thaiv cov khob ntawv puas.
Cursor positioning: Lub photoelectric sensor cia li txheeb xyuas cov xim xim ntawm lub ntim zaj duab xis, nrhiav qhov chaw sib khi kom raug, thiab tswj qhov yuam kev mus rau ± 1mm.
Pwm adaptability
Txhua yam -aluminium pwm (CNC precision engraving) yog mus txog 0.001mm nyob rau hauv qhov tseeb thiab txhawb ntau yam ntawm specifications ntawm "1/1" mus rau "6/1." Cov pwm tuaj yeem hloov pauv sai sai nyob ntawm cov duab ntawm lub khob (xws li puag ncig, square, alien ntawv khob).
III. Sealing khoom thiab txheej txheem
Cov khoom ntawm PP zaj duab xis
PP (polypropylene) zaj duab xis muaj qhov zoo ntawm qhov kub thiab txias, puncture tsis kam thiab siab transparency. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias:
Ib qho -cov khoom siv polypropylene zaj duab xis: Pulse heat sealing lossis qis-kub ntev- lub sijhawm sealing yuav tsum tau vim nws yooj yim rau yaj thiab nyias thaum overheated.
PP zaj duab xis sib xyaw: xws li PP / PE zaj duab xis, qhov qis melting point ntawm PE txheej tuaj yeem siv tau kom ua tiav qhov qis qis - kub sealing, txo qhov kev pheej hmoo ntawm PP txheej deformation.
Sealing txheej txheem optimization
Ua kom txias thiab teeb tsa: tom qab sealing Lub nplhaib nplhaib hom sealing tshuab los ntawm lub tshuab ua kom txias kom txias sai, tiv thaiv zaj duab xis shrinkage.
Anti-kev kho adhesion: cua sov phaj lossis cua sov rau cov menyuam nto coated nrog polytetrafluoroethylene (PTFE), kom tsis txhob muaj zaj duab xis adhesion, ncua cov khoom siv lifespan.
