Ukukhipha izinto kuyinqubo yokukhiqiza ehilela ukudlulisa izinto ngedayi ukuze kudalwe into enephrofayili eqinile yesigaba esinqamulelayo. Ubuchwepheshe busetshenziswa ezimbonini eziningana okuhlanganisa ipulasitiki, izinsimbi, ukudla kanye nemithi. Imishini esetshenziswa enqubweni yokukhipha izinto yenzelwe ngqo ukuhlangabezana nezidingo ezihlukile zezinto ezikhishwayo ukuqinisekisa ukusebenza kahle nokunemba. Kulesi sihloko, sizobheka izinhlobo ezahlukene zemishini esetshenziswa enqubweni yokukhipha izinto, izingxenye zayo, kanye nendlela esebenza ngayo.
1. Isikhiphi Esisodwa Sesikulufa
I-single screw extruder uhlobo oluvame kakhulu lwe-extruder. Yakhiwe yi-screw eyindilinga ejikelezayo emgqonyeni oyindilinga. Izinto ezisetshenziswayo zifakwa kwi-hopper lapho zifudunyezwa khona futhi zincibilike njengoba zihamba ngesikulufu. Ukwakheka kwesikulufu kuvumela ukuthi izinto zixutshwe, zincibilike futhi zipompelwe ekhanda le-die. Ama-single screw extruder anezinto eziningi futhi angasetshenziswa ezintweni eziningi ezahlukene, kufaka phakathi ama-thermoplastic kanye nama-thermoset athile.
2. I-Extruder Yesikulufu Esiphindwe Kabili
Ama-extruder e-twin-screw anezikulufo ezimbili ezihlanganayo ezijikeleza ohlangothini olufanayo noma oluphambene. Lo mklamo uvumela ukuxubana okungcono futhi ulungele izinhlelo zokusebenza ezidinga izinga eliphezulu lokufana. Ama-extruder e-twin-screw avame ukusetshenziswa ekukhiqizweni kokudla, imithi kanye nezinto ze-polymer ezithuthukisiwe. Ama-extruder e-twin-screw angacubungula nohlu olubanzi lwezinto, kufaka phakathi izinto ezizwela ukushisa.
3. Isikhiphi se-Plunger
Ama-extruder e-Plunger, aziwa nangokuthi ama-extruder e-piston, asebenzisa i-plunger ephindaphindayo ukuze asunduze izinto nge-diye. Lolu hlobo lwe-extruder luvame ukusetshenziselwa izinto okunzima ukuzicubungula ngama-screw extruder, njenge-ceramics nezinsimbi ezithile. Ama-extruder e-Plunger angafinyelela ukucindezeleka okuphezulu kakhulu futhi ngenxa yalokho afaneleka ezinhlelweni ezidinga ama-extruder aphezulu kanye namandla.
4. Izinto zokukhipha amashidi
Ama-extruder eshidi ayimishini ekhethekile yokukhiqiza amashidi ayisicaba. Ngokuvamile asebenzisa inhlanganisela ye-extruder eyodwa noma ezimbili kanye ne-diye ukuze akhiphe izinto zibe yishidi. Ishidi elikhishwe lingapholiswa futhi lisikwe libe osayizi abafanele ukusetshenziswa okuhlukahlukene, okuhlanganisa ukupakisha, ukwakhiwa kanye nezingxenye zezimoto.
5. I-extruder yefilimu eqhumile
I-Blown film extruder inqubo ekhethekile esetshenziselwa ukukhiqiza amafilimu epulasitiki. Kule nqubo, ipulasitiki encibilikisiwe ikhishwa nge-diye eyindilinga bese inwetshwa ukuze yakhe amabhamuza. Amabhamuza ayaphola futhi anciphe ukuze akhe ifilimu eyisicaba. Ama-Blown film extruder asetshenziswa kabanzi embonini yokupakisha ukukhiqiza izikhwama, iphepha lokusonga nezinye izinto zokupakisha eziguquguqukayo.
Ake sibonise inkampani yethuUmhlinzeki womshini wokuvuthela ifilimu ohlanganisa ungqimba oluphindwe kabili we-LQ 55 (Ububanzi befilimu 800MM)
I-extruder inezingxenye eziningana ezibalulekile ezisebenzisana ukuqinisekisa ukucutshungulwa kwezinto okuphumelelayo:
I-Hopper: I-hopper yilapho izinto zokusetshenziswa zifakwa khona emshinini. Yenzelwe ukufaka izinto zokusetshenziswa njalo ku-extruder.
Isikulufu: Isikulufu siyinhliziyo yomshini wokukhipha. Sinesibopho sokudlulisa, ukuncibilikisa nokuxuba izinto zokusetshenziswa njengoba sidlula emgqonyeni.
Umgqomo: Umgqomo uyigobolondo eliyindilinga eliqukethe isikulufu. Umgqomo uqukethe izinto zokushisa zokuncibilikisa izinto futhi ungase ube nezindawo zokupholisa zokulawula izinga lokushisa.
Idayi: Idayi iyisakhi esibumba izinto ezikhishwe zibe yisimo esifunwayo. Amadayi angenziwa ngokwezifiso ukuze adale izimo ezahlukene zezinto ezifana nepayipi, ishidi noma ifilimu.
Uhlelo Lokupholisa: Ngemva kokuba izinto ziphume edayeni, ngokuvamile kudingeka zipholiswe ukuze zigcine isimo sazo. Izinhlelo zokupholisa zingafaka phakathi amabhavu amanzi, ukupholisa umoya, noma imiqulu yokupholisa, kuye ngokuthi isetshenziswa kanjani.
Izinhlelo Zokusika: Kwezinye izinhlelo zokusebenza, izinto ezikhishwe kungadingeka zinqunywe zibe nobude obuthile. Izinhlelo zokusika zingafakwa emgqeni wokukhipha ukuze zenze le nqubo ibe ngokuzenzakalelayo.
Inqubo yokukhipha iqala ngokulayisha izinto ezingavuthiwe ku-hopper. Izinto ezingavuthiwe zibe sezifakwa emgqonyeni lapho zifudunyezwa khona futhi zincibilike njengoba zihamba ngesikulufu. Isikulufu senzelwe ukuxuba kahle izinto ezingavuthiwe bese sizipompa kudayi. Uma izinto sezifikile kudayi, ziphoqelelwa ukuthi zidlule embotsheni ukuze zakhe isimo esifiselekayo.
Ngemva kokuba i-extrudate ishiye i-die, iyaphola futhi iqine. Kuye ngohlobo lwe-extruder kanye nezinto ezisetshenzisiwe, kungase kudingeke kwenziwe ezinye izinyathelo, njengokusika, ukugoqa noma ukucubungula okwengeziwe.
Ukukhipha izinto kuyinqubo ebalulekile yokukhiqiza encike emishinini ekhethekile ukukhiqiza imikhiqizo eyahlukahlukene. Kusukela kuma-extruder anezikulufo ezi-single kanye nama-twin-screw kuya kuma-plunger extruder kanye nemishini yamafilimu aqhunyisiwe, uhlobo ngalunye lwe-extruder lunenhloso ehlukile embonini. Ukuqonda izingxenye nemisebenzi yale mishini kubalulekile ekwenzeni ngcono inqubo yokukhipha izinto futhi kufinyelelwe imiphumela esezingeni eliphezulu. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, imboni yokukhipha izinto cishe izobona ezinye izinto ezintsha ezizokwandisa ukusebenza kahle futhi zandise amathuba okucubungula izinto.
