1, Cov qauv kev ua haujlwm sib txawv
1. Txhaj tshuaj molding tshuab
Lub hauv paus ntsiab lus ua haujlwm ntawm lub tshuab txhaj tshuaj molding zoo ib yam li cov koob txhaj tshuaj rau kev txhaj tshuaj. Nws yog cov txheej txheem ntawm txhaj cov yas yas molten (xws li viscous ntws) mus rau hauv cov pwm kab noj hniav kaw nrog kev pab los ntawm kev sib tw ntawm cov ntsia hlau (los yog plunger), thiab tau txais cov khoom tom qab kho thiab shaping.
Kev txhaj tshuaj molding yog txheej txheem voj voog, txhua lub voj voog feem ntau suav nrog: kev pub noj ntau - yaj thiab yas - kev txhaj tshuaj siab - pwm filling thiab txias - pwm qhib thiab noj cov khoom. Tom qab tshem tawm cov yas, kaw cov pwm dua rau lub voj voog tom ntej.
2. Extruder
Qhov ntev ntev ntawm ib qho ntsia hlau feem ntau muab faib ua peb ntu. Qhov ntev ntawm peb ntu yog txiav txim siab raws li cov ntsia hlau txoj kab uas hla, lub suab thiab ntsia hlau qhov tob, uas feem ntau muab faib raws li ib feem peb ntawm txhua qhov.
Cov xov kawg ntawm cov khoom qhib yog hu ua seem conveying: cov khoom ntawm no yuav tsum tsis txhob yuav plasticized, tab sis yuav tsum tau preheated thiab compacted nyob rau hauv siab. Yav dhau los, txoj kev xav extrusion qub xav tias cov khoom ntawm no yog xoob. Tom qab ntawd, nws tau ua pov thawj tias cov khoom ntawm no yog cov khoom ntsaws, uas yog, cov khoom ntawm no yog cov khoom zoo li lub ntsaws tom qab extruded. Yog li ntawd, ntev npaum li cas txoj haujlwm conveying tiav, nws yog nws txoj haujlwm.
2, Cov yam ntxwv sib txawv
1. Txhaj tshuaj molding tshuab
Cov cuab yeej txhaj tshuaj thiab cov pwm xauv cov cuab yeej yog nyob rau ntawm tib txoj kab ntsug ntsug, thiab cov pwm qhib thiab kaw raws li qhov nce thiab nqis. Nws thaj chaw hauv pem teb tsuas yog kwv yees li ib nrab ntawm cov tshuab kab rov tav. Yog li ntawd, cov khoom tsim tau hloov dua siab tshiab rau hauv pem teb yog li ob zaug.
2. Extruder
Cov khoom muaj kev nyab xeeb uas lub extruder yuav tsum tau them sai sai rau thaum lub sij hawm extrusion muaj xws li: hluav taws xob, thermal, mechanical rotation, loading thiab unloading ntawm hnyav qhov chaw, thiab lwm yam. Lub extrusion locomotive chav yuav tsum tau nruab nrog lifting khoom los sib sau ua ke thiab disassemble hnyav qhov chaw xws li tshuab taub hau. thiab ntsia hlau kom ruaj ntseg ntau lawm.
3, Kev faib tawm txawv
1. Txhaj tshuaj molding tshuab
Kev faib tawm los ntawm txoj kev plasticization
1) Plunger hom yas txhaj tshuaj molding tshuab
Nws cov khoom sib xyaw yog qhov tsis zoo thiab nws cov plasticization tsis zoo. Nws yog ib qho tsim nyog rau nruab ib lub tshuab shunting shuttle. Nws tsis tshua siv.
2) Reciprocating ntsia hlau hom yas txhaj tshuaj molding tshuab;
Nyob ntawm cov ntsia hlau rau plasticization thiab txhaj tshuaj, kev sib xyaw thiab plasticization yog qhov zoo heev, uas yog siv feem ntau.
3) Ntsia Hlau - plunger yas txhaj tshuaj molding tshuab cia siab rau cov ntsia hlau rau plasticization thiab plunger rau kev txhaj tshuaj. Ob txheej txheem sib cais.
2. Extruder
Yas extruders muab faib ua ib qho ntsia hlau extruders thiab ntxaib-ntsia hlau extruders.
