Kuumba phula, komwe kumadziwikanso kuti hollow blowing, ndi njira yopangira pulasitiki yomwe ikukula mwachangu.Pa Nkhondo Yachiwiri Yapadziko Lonse, njira yowumba nkhonya idayamba kugwiritsidwa ntchito kupanga mbale zotsika kwambiri za polyethylene.Chakumapeto kwa zaka za m'ma 1950, ndi kubadwa kwa polyethylene yochuluka kwambiri komanso kukula kwa makina opangira nkhonya, teknoloji yowomba nkhonya idagwiritsidwa ntchito kwambiri.Kuchuluka kwa zotengera zopanda kanthu kumatha kufika malita masauzande ambiri, ndipo kupanga kwina kwatengera makompyuta.The mapulasitiki oyenera kuwombera akamaumba monga polyethylene, polyvinyl mankhwala enaake, polypropylene, poliyesitala, etc. The chifukwa muli dzenje chimagwiritsidwa ntchito monga zotengera mafakitale ma CD.Malinga ndi njira yopanga parison, kuumba nkhonya kungathe kugawidwa mu extrusion nkhonya akamaumba ndi jekeseni kuwomba akamaumba.Zomwe zangopangidwa kumene ndikuwomba kwamitundu yambiri komanso kuwongola kotambasula.
Jekeseni kutambasula kuwomba kuumba
Pakadali pano, ukadaulo wowotcha jekeseni umagwiritsidwa ntchito kwambiri kuposa kuumba jekeseni.Njira yopangira nkhonya iyi ndiyonso kuumba jekeseni, koma imangowonjezera kugwedezeka kwa axial, kupangitsa kuumba kukhala kosavuta komanso kuchepetsa kugwiritsa ntchito mphamvu.Kuchuluka kwa zinthu zomwe zingathe kukonzedwa ndi kujambula jekeseni ndi kuwomba ndi zazikulu kuposa zomwe zimawombera jekeseni.Kuchuluka kwa chidebe chomwe chitha kuwomberedwa ndi 0.2-20L, ndipo ntchito yake ndi motere:
1. Mfundo yopangira jekeseni ndi yofanana ndi ya jekeseni wamba.
2. Kenako tembenuzirani parison kuti ikhale yotentha komanso yowongolera kutentha kuti parison ikhale yofewa.
3. Tembenukira kumalo okokera ndikutseka nkhungu.Kukankhira ndodo pachimake kumatambasula parison motsatira njira ya axial, ndikuwomba mpweya kuti parisonyo ikhale pafupi ndi khoma la nkhungu ndikuziziritsa.
4. Kusamutsira ku demoulding station kuti mutenge mbali
Chidziwitso - kukoka - kuwomba:
Jekeseni womangira parishi → kutenthetsa parishi → kutseka, kujambula ndi kuwomba → kuziziritsa ndi kutenga mbali
Chithunzi chojambula cha makina a jakisoni, kujambula ndi kuwomba
Kukonzekera kwa extrusion
Extrusion blowing akamaumba ndi imodzi mwa anthu ambiri ntchito kuwomba akamaumba njira.Kukonzekera kwake kumakhala kotakata kwambiri, kuchokera kuzinthu zazing'ono kupita kuzinthu zazikulu ndi ziwalo zamagalimoto, mankhwala opangira ndege, ndi zina zotero.
1. Choyamba, sungunulani ndi kusakaniza mphira, ndipo kusungunuka kumalowa mu mutu wa makina kuti mukhale parison tubular.
2. Pambuyo pa parison kufika utali wokonzedweratu, kuwomba akamaumba nkhungu chatsekedwa ndipo parison ndi clamped pakati pa theka ziwiri za nkhungu.
3. Wombani mpweya, womberani mpweya mu parison, womberani parison kuti ikhale pafupi ndi nkhungu yopangira nkhungu.
4. Kuzizira mankhwala
5. Tsegulani nkhungu ndikuchotsani zinthu zolimba.
Njira yopangira extrusion:
Kusungunuka → parishi yotuluka → kutseka kwa nkhungu ndikuwumba → kutseguka kwa nkhungu ndi kutenga mbali
Schematic chithunzi cha extrusion blow molding mfundo
(1 - extruder mutu; 2 - kuwomba nkhungu; 3 - parison; 4 - wothinikizidwa mpweya kuwomba chitoliro; 5 - pulasitiki mbali)
Jekeseni nkhonya akamaumba
Jekeseni nkhonya akamaumba ndi akamaumba njira kuphatikiza makhalidwe a jekeseni akamaumba ndi kuwomba akamaumba.Pakalipano, amagwiritsidwa ntchito makamaka ku mabotolo akumwa, mabotolo amankhwala ndi tizigawo tating'ono tating'ono tating'onoting'ono tambirimbiri.
1. Mu siteshoni yopangira jakisoni, jekeseni wa nkhungu poyamba, ndipo njira yopangira jekeseni ndi yofanana ndi ya jekeseni wamba.
2. Pambuyo jekeseni nkhungu kutsegulidwa, mandrel ndi parison amasamukira ku siteshoni yowomba.
3. The mandrel amaika parison pakati nkhonya akamaumba zisamere pachakudya ndi kutseka nkhungu.Kenako, mpweya woponderezedwawo umawomberedwa mu parison kudutsa pakati pa mandrel, ndiyeno amawombedwa kuti ukhale pafupi ndi khoma la nkhungu ndikuzirala.
4. Pamene nkhungu imatsegulidwa, mandrel amasamutsidwa ku siteshoni yowonongeka.Pambuyo pakuwumbidwa nkhonya kuchotsedwa, mandrel amasamutsidwa kupita kumalo ojambulira kuti ayendetse.
Njira yogwiritsira ntchito jakisoni blower:
Limbani pomanga parishi → jekeseni nkhungu kutsegulira poulutsira filimu → kutseka nkhungu, kuumba ndi kuziziritsa → kuzungulira kupita ku siteshoni kuti mutenge mbali → parison
Chithunzi chojambula cha jekeseni wowuma jekeseni
Ubwino ndi kuipa kwa jakisoni wowotchera:
mwayi
Mankhwalawa ali ndi mphamvu zambiri komanso zolondola kwambiri.Palibe olowa pa chidebe ndipo palibe chifukwa chokonza.Kuwonekera komanso kutha kwa pamwamba pazigawo zowumbidwa ndi nkhonya ndizabwino.Amagwiritsidwa ntchito kwambiri popanga matumba apulasitiki olimba komanso zotengera zapakamwa zazikulu.
chopereŵera
Mtengo wa zida zamakina ndizokwera kwambiri, komanso kugwiritsa ntchito mphamvu kumakhala kwakukulu.Nthawi zambiri, zotengera zazing'ono zokha (zosakwana 500ml) zitha kupangidwa.Ndizovuta kupanga zotengera zokhala ndi mawonekedwe ovuta komanso zinthu za elliptical.
Kaya ndi jekeseni kuwomba akamaumba, jekeseni kukoka nkhonya akamaumba, extrusion kukoka kuwomba kuwomba, izo lagawidwa mu nthawi imodzi akamaumba ndi kawiri akamaumba ndondomeko.Njira yopangira nthawi imodzi imakhala ndi makina apamwamba kwambiri, kulondola kwambiri kwa ma parison clamping ndi indexing system, komanso mtengo wapamwamba wa zida.Nthawi zambiri, opanga ambiri amagwiritsa ntchito njira yopangira kawiri, ndiye kuti, kuumba tchalitchi choyamba kudzera mu jekeseni kapena kutulutsa, ndikuyika tchalitchicho mu makina ena (makina ojambulira jekeseni kapena makina opangira jekeseni) kuti atulutse chinthu chomalizidwa, chokwera kwambiri. kupanga bwino.
