Ob lub ntsia hlau #tshuab riam Feem ntau siv rau hauv kev tsim khoom yas thiab kev ua cov yas. Hauv cov txheej txheem ua khoom tiag tiag, lub tshuab extruder twin-screw siv nws cov kev ua tau zoo tshaj plaws los txhim kho kev siv cov khoom siv thiab txo cov khoom seem hauv lub tshuab extruder. Raws li kev nthuav dav ntawm qhov ntsuas ntawm kev tsim khoom thiab kev ua cov yas hloov kho tau muab cov kev cai siab dua rau kev ua haujlwm ntawm lub tshuab extruder twin-screw nws tus kheej.
Kev kho dua tshiab ntawm lub thawv txias
Los ntawm kev ntxiv lub thawv txias rau hauv lub twin-screw extruder, kev txhim kho thiab kev ua kom zoo dua ntawm cov txheej txheem ntau lawm ntawm twin-screw #yas extruder tau pom tseeb. Hauv cov txheej txheem tsim khoom extrusion tiag tiag, lub cuab yeej tswj cov av noo ntxiv rau hauv lub thawv txias, uas txo qhov poob txias ntawm cov khoom yas, thiab nyob rau hauv kev teeb tsa ntawm cov vaj huam sib luag rwb thaiv tsev kub, cua ncig tau tsim los xyuas kom meej tias cov khoom nyob rau hauv qhov xwm txheej zoo ntawm kev sib cais, thiab cov nyhuv dissipation yog qhov pom tseeb; cov saw hlau hauv lub thawv txias ua kom zoo dua hom kev sib kis ntawm cov khoom yas, thiab los ntawm kev kho qhov zaus ntawm lub cev muaj zog tseem ceeb, lub thawv txias thiab lub twin-screw extruder khiav synchronously; nrog kev txhawb nqa ntawm tus pas nrig txhawb nqa, qhov deb ntawm cov khoom yas thiab lub thawv sib cuag tau nqaim kom tiv thaiv kev nplaum. Txhawm rau kom ua tau raws li qhov xav tau tiag tiag, ua tiav lub hom phiaj ntawm kev txhim kho qhov zoo ntawm cov khoom yas, xyuas kom meej tias muaj ntau yam ntawm cov khoom yas tsim tawm, thiab nthuav dav ntau yam kev siv thiab thaj chaw ntawm twin-screw extruder.
Kev txhim kho ntawm lub cuab yeej pub sab ntawm lub tshuab twin-screw #extrusion
Txo cov huab cua sib xyaw hauv cov txheej txheem pub mis
Muaj ib lub qhov tso pa tawm uas teeb tsa rau sab saud ntawm lub qhov pub sab, lub hau qub raug hloov nrog lub hau hlau, thiab lub qhov pub sab muab faib ua ob ntu, sab pem hauv ntej siv rau kev tso pa tawm thiab sab nraub qaum siv rau kev pub. Lub hau hlau txhawb nqa qhov kev sib zog ntawm cov khoom ntim thaum lub sijhawm pub, thiab maj mam tso cov huab cua sib xyaw los ntawm sab pem hauv ntej ntawm lub qhov pub, thiab thaum kawg tso cov huab cua los ntawm lub qhov tso pa tawm sab saud ntawm lub qhov pub sab.
Qhov chaw pub dawb yog tseg rau qhov chaw pub mis rau ib sab
Los ntawm kev ua kom qhov chaw pub dawb ntawm ib sab ntawm qhov chaw pub khoom noj, qhov yuav tsum tau ntim khoom tiag tiag raug ua tiav. Raws li qhov no, ib lub ntsia hlau loj-lead yog tsim los ntawm lub hauv paus ntawm cov ntsia hlau uas twb muaj lawm, ib lub ntsia hlau asymmetric yog teeb tsa rau sab saud ntawm qhov chaw pub khoom noj ntawm sab ntawm cov ntsia hlau, ib lub khoom xa rov qab yog tsim rau ib sab ntawm qhov chaw pub khoom noj ntawm sab ntawm cov ntsia hlau, thiab ib lub khoom xa rov qab yog tsim rau sab tod. Thaum cov khoom siv raug thauj los ntawm lub extruder, cov khoom siv nkag mus rau hauv qhov chaw pub khoom noj tseem ceeb thiab nkag mus rau hauv lub extruder. Lub ntsia hlau txuas ntxiv mus rau pem hauv ntej thiab raug cua sov thiab yaj. Thaum cov khoom siv mus txog qhov chaw asymmetric, nws nyob rau hauv lub xeev molten. Nyob rau hauv qhov kev ua ntawm lub ntsiab lus asymmetric, lub xeev faib khoom ntawm cov khoom siv hloov pauv ntau heev. Qhov chaw pub khoom noj ntawm ib sab yog thauj mus rau sab nraud, thiab sab tod yog thauj mus rau sab nraud. Synchronous reverse conveying, nyob rau hauv cov txheej txheem ntawm kev xa rov qab ntawm cov khoom siv, ib sab ntawm qhov chaw pub khoom noj tsim ib lub qhov nyob rau hauv qhov kev ua ntawm lub ntsiab lus xa rov qab, uas ua rau ntau ntxiv ntawm cov khoom sau ntxiv rau sab pub khoom noj.
Ob chav pub mis
Hom kev pub ib zaug thawj zaug tau hloov mus ua hom kev pub ob lub qhov (dual-port simultaneous feeding mode) los tsim ib lub "dual-feeding system". Thaum lub sijhawm hloov pauv tiag tiag, pom tias cov gaskets hauv qab lub kaw lus pub tau raug tshem tawm hauv qab kev co. Hauv qhov kev hloov pauv thib ob, tau ntxiv ib lub bracket ruaj khov kom daws tau qhov teeb meem kev hloov pauv kev co, ua kom zoo dua cov txheej txheem ntim khoom thiab cov txuas, thiab ua tiav lub hom phiaj ntawm kev sib tov, extrusion, thiab shearing ntawm cov ntaub ntawv tseem ceeb ntawm qee qhov kub, thiab qhov zoo ntawm cov khoom tom qab tsim khoom thiab ua tiav yog siab dua.
Nrog yuav luag 20 xyoo hauv kev lag luam khoom siv extrusion ntse, nws tau tuav lub luag haujlwm tseem ceeb ntawm Jwell Machinery, suav nrog Tus Thawj Coj General thiab Tus Thawj Coj Hloov Chaw. Txij li xyoo 2024, nws tau tswj hwm ntau lub tuam txhab me, tsav kev nthuav dav lag luam thiab kev txhim kho kev lag luam, thaum ua tus thawj coj hauv kev tsim khoom ntse thiab kev loj hlob thoob ntiaj teb.
