Kutulutsa zinthu ndi njira yopangira zinthu yomwe imaphatikizapo kudutsa zinthu kudzera mu die kuti apange chinthu chokhala ndi mawonekedwe okhazikika. Ukadaulowu umagwiritsidwa ntchito m'mafakitale angapo kuphatikiza mapulasitiki, zitsulo, chakudya ndi mankhwala. Makina omwe amagwiritsidwa ntchito potulutsa zinthu adapangidwa mwapadera kuti akwaniritse zofunikira zapadera za zinthu zomwe zikutulutsidwa kuti zitsimikizire kuti zikugwira ntchito bwino komanso molondola. M'nkhaniyi, tiwona mitundu yosiyanasiyana ya makina omwe amagwiritsidwa ntchito potulutsa zinthu, zigawo zake, ndi momwe amagwirira ntchito.
1. Chotulutsira Chokha Chokha
Chotulutsira cholukira chimodzi ndi mtundu wofala kwambiri wa chotulutsira. Chimakhala ndi chokulungira chozungulira chomwe chimazungulira mu mbiya yozungulira. Zipangizozo zimayikidwa mu hopper komwe zimatenthedwa ndikusungunuka pamene zikuyenda motsatira chokulungira. Kapangidwe ka chokulungirako kamalola kuti zinthuzo zisakanizidwe, kusungunuka ndikupopedwa ku mutu wa die. Zotulutsira zolukira chimodzi ndi zosinthika kwambiri ndipo zingagwiritsidwe ntchito pazinthu zosiyanasiyana, kuphatikizapo thermoplastics ndi ma thermosets ena.
2. Chotulutsira Ma Screw Twin
Zotulutsira zinthu za twin-screw zili ndi zokulungira ziwiri zolumikizana zomwe zimazungulira mbali imodzi kapena yosiyana. Kapangidwe kameneka kamalola kusakaniza bwino ndi kusakanikirana ndipo ndi koyenera kugwiritsa ntchito zomwe zimafuna kufanana kwakukulu. Zotulutsira zinthu za twin-screw nthawi zambiri zimagwiritsidwa ntchito popanga chakudya, mankhwala ndi zipangizo zamakono za polima. Zotulutsira zinthu za twin-screw zimathanso kukonza zinthu zosiyanasiyana, kuphatikizapo zinthu zomwe zimakhudzidwa ndi kutentha.
3. Chotulutsira cha Plunger
Zipangizo zotulutsira zinthu zopopera, zomwe zimadziwikanso kuti zotulutsira zinthu zopopera, zimagwiritsa ntchito chopopera chobwerezabwereza kuti zikankhire zinthu kudzera mu die. Mtundu uwu wa chotulutsira zinthu nthawi zambiri umagwiritsidwa ntchito pazinthu zomwe zimakhala zovuta kuzikonza ndi zotulutsira zinthu zopopera, monga ziwiya zina zadothi ndi zitsulo. Zipangizo zotulutsira zinthu zopopera zimatha kufika pamavuto akulu kwambiri ndipo motero ndizoyenera kugwiritsidwa ntchito pofunikira zotulutsira zinthu zopopera kwambiri komanso zamphamvu.
4. Zotulutsira mapepala
Makina otulutsira mapepala ndi makina apadera opangira mapepala athyathyathya. Nthawi zambiri amagwiritsa ntchito chotulutsira chimodzi kapena ziwiri ndi die kuti atulutse zinthuzo mu pepala. Pepala lotulutsira limatha kuziziritsidwa ndikudulidwa m'makulidwe oyenera kugwiritsidwa ntchito m'njira zosiyanasiyana, kuphatikizapo kulongedza, kumanga ndi zida zamagalimoto.
5. chotulutsira filimu chophulika
Chotulutsira filimu yophwanyika ndi njira yapadera yomwe imagwiritsidwa ntchito popanga mafilimu apulasitiki. Munjira imeneyi, pulasitiki yosungunuka imatulutsidwa kudzera mu die yozungulira kenako nkukulitsidwa kuti ipange thovu. Thovulo limazizira ndikuchepa kuti lipange filimu yathyathyathya. Zotulutsira filimu yophwanyika zimagwiritsidwa ntchito kwambiri mumakampani opanga ma CD popanga matumba, mapepala okutira ndi zinthu zina zosinthika zotulutsira.
Tiyeni tiwonetse kampani yathuWogulitsa makina opukutira filimu a LQ 55 okhala ndi zigawo ziwiri (Kutalika kwa filimu 800MM)
Chotulutsiracho chimakhala ndi zigawo zingapo zofunika zomwe zimagwirira ntchito limodzi kuti zitsimikizire kuti zinthuzo zikugwira ntchito bwino:
Hopper: Hopper ndi komwe zinthu zopangira zimayikidwa mu makina. Yapangidwa kuti ipereke zinthu zopangira nthawi zonse mu extruder.
Sikulu: Sikulu ndi mtima wa chotulutsira mpweya. Chimayang'anira kunyamula, kusungunula ndi kusakaniza zinthu zopangira pamene zikudutsa mu mbiya.
Mbiya: Mbiya ndi chipolopolo chozungulira chomwe chili ndi screw. Mbiyayo ili ndi zinthu zotenthetsera zomwe zimasungunula zinthuzo ndipo ikhoza kukhala ndi malo ozizira owongolera kutentha.
Die: Die ndi chinthu chomwe chimapanga zinthu zomwe zatulutsidwa kukhala mawonekedwe omwe mukufuna. Dies zimatha kusinthidwa kuti zipange mawonekedwe osiyanasiyana azinthu monga chitoliro, pepala kapena filimu.
Njira Yoziziritsira: Zinthuzo zikachoka mu die, nthawi zambiri zimafunika kuziziritsidwa kuti zisunge mawonekedwe ake. Njira zoziziritsira zimatha kuphatikizapo madzi osambira, mpweya wozizira, kapena ma roll ozizira, kutengera momwe zimagwiritsidwira ntchito.
Machitidwe Odulira: Mu ntchito zina, zinthu zotulutsidwa zingafunike kudulidwa m'litali linalake. Machitidwe odulira amatha kuphatikizidwa mu mzere wotulutsira kuti izi zitheke zokha.
Njira yotulutsira zinthu imayamba ndi kuyika zinthu zopangira mu hopper. Kenako zinthu zopangirazo zimayikidwa mu mbiya komwe zimatenthedwa ndikusungunuka pamene zikuyenda motsatira sikuru. Sikuruyo imapangidwa kuti isakanize bwino zinthu zopangirazo ndikuzipopera mu die. Zinthuzo zikafika pa die, zimakakamizika kudutsa m'malo otseguka kuti zipange mawonekedwe omwe mukufuna.
Chotulutsa chikachoka mu die, chimazizira ndi kuuma. Kutengera mtundu wa chotulutsa ndi zinthu zomwe zagwiritsidwa ntchito, njira zina zingafunike kuchitidwa, monga kudula, kupotoza kapena kukonza zina.
Kutulutsa zinthu ndi njira yofunika kwambiri yopangira zinthu yomwe imadalira zida zapadera kuti ipange zinthu zosiyanasiyana. Kuyambira zotulutsira zinthu zokhala ndi sikelo imodzi ndi ziwiri mpaka zotulutsira zinthu zokhala ndi sikelo imodzi ndi makina opangira mafilimu ophulika, mtundu uliwonse wa chotulutsira zinthu uli ndi cholinga chake pamakampaniwa. Kumvetsetsa zigawo ndi ntchito za makinawa ndikofunikira kwambiri kuti njira yotulutsira zinthu izi igwire bwino ntchito komanso kuti pakhale zotsatira zabwino kwambiri. Pamene ukadaulo ukupitirira, makampani opanga zinthu zotulutsira zinthu mwina awona zatsopano zina zomwe zingathandize kuti zinthu zigwire bwino ntchito ndikuwonjezera mwayi wokonza zinthu.
