Umugqa wokukhiqiza we-PET sheet extrusion
Ukuchazwa komugqa wonke:
Isivinini esiphezulu se-PE, i-PP, i-PS, i-ABS, i-PMMA, umugqa wokukhiqiza weshidi le-PET weshidi lokukhiqiza
Lokhu kucaciswa kuhlanganisa ubuchwepheshe bokukhiqiza ulayini wokukhiqiza weshidi le-PET, okubandakanya ukwakheka kokuphakelayo, i-extruder, ulayini wokuncibilika (okubandakanya ukuhlunga kanye nemitha), ikhanda lokufa, ukuphonsa, ukudonsa nokujika, njll.
Umugqa wokukhiqiza we-PET imvelo ukuvikela ukupakishwa kwe-extrusion wakhiwa ikakhulukazi i-extruder ephindwe kabili, i-mesh change, iphampu yemitha, ukufa, ama-roller amathathu, ubakaki wokupholisa, ukudonsa, ukujikajika nokunye.Uhlobo olusha lwe-co-directionadouble-sided extruder lunezici zokusetshenziswa kwamandla okuphansi, inqubo elula nokugcinwa kalula kwemishini.Isakhiwo sayo esiyingqayizivele sokuhlanganisa isikulufu kunciphisa ukwehla kwe-viscosity kwe-PET resin.Irola enezindonga ze-symmetricathin ithuthukisa ukusebenza kahle kokupholisa kanye nokukhiqiza njengoba ithuthukisa ikhwalithi yamashidi.Idivayisi yokuphakela izingxenye eziningi ingaphazamisa ngokunengqondo ingxenye yezinto ezintsha, izinto zokugaya kabusha, i-masterbatch nokunye.Amashidi akhiqizwayo angasetshenziswa emkhakheni wokuphrinta nokupakishwa kwepulasitiki.Uhlelo lukagesi lwamukela i-Siemens subsystem, ebonakala ngokusebenza okulula, ukuzenzekelayo okuphezulu nokonga izindleko.

I-Twin screw host SHJ-75-132kw—40:1
I-extruder yeshidi yenziwe nge-extrusion, ikhalenda, ukudonsa nokugingqa.Izingxenye eziyinhloko azikwazi ukumelana nokuhuzuka, zimelana nokugqwala, izinga lokushisa eliphezulu amelana nekhwalithi ephezulu elashwe ngokukhethekile.Amandla okumelana aphansi ku-die head extruding channemakes sheet ukujiya ngokulinganayo, i-internaspiratank kuma-roller amathathu iqinisekisa ukupholisa okuphumelelayo futhi kulula ukuyishintsha kanye nokushintsha kwe-instalnet ngeyunithi ye-hydraulic pressure, asikho isidingo sokumisa umshini.Umshini ukhipha imishini ye-PP/PS/PET thermoforming, njengezinkomishi, isitsha sokudla, amathreyi, izitsha, izitsha, izivalo, njll.

ukuhlanganisa
I-Gearbox:Isinciphisi setorque ephezulu.
Ukunciphisa isivinini kanye nokusabalalisa kwe-torque kuhlanganiswe ukuze kuqiniswe umklamo wokuthwala umthamo;
Igiya lenziwe ngensimbi ye-alloy yekhwalithi ephezulu.Ngemuva kwe-carburizing kanye nokucisha, igiya ligaywe kahle.Ukunemba komshini kungaphezu kwebanga lesi-5. Ukuqina kwezinyo kufinyelela ku-hrc60-65.Iphrofayili yezinyo kanye ne-helix ishintshiwe ukuze kuqinisekiswe ukubandakanyeka okuphelele kwegiya ngaphansi komthwalo, ngomsindo ophansi kanye ne-torque enkulu yokudlulisela;
Ama-bearings ngokuvamile amabhrendi adumile emhlabeni wonke, njenge-NSK, FAG, TWB, SKF, ZWZ kanye ne-HRB;
I-oillubrication system ithatha ngokuyinhloko ukugcotshwa kwe-oiimmersion kanye nokugcotshwa kwamaphuzu amaningi ukuze kuqinisekiswe ukuthi amapheya ahambayo ahlala egcotshisiwe;
Isakhiwo esisha esiklanyelwe sokuvala kanye nendandatho yokuvala uphawu evela kwamanye amazwe iqinisekisa ukusebenza okuhle kakhulu kokufakwayo nokuphumayo;

Okwesistimu ye-Pet electric drive
Imishini yepulasitiki ye-Qingdao cuishi esetshenziswa I-Pet electric drive system isetshenziselwa ukuhlinzeka ngemishini yokushayela yezigaba ezahlukahlukene zezilwane ezifuywayo, okuhlanganisa iyunithi enkulu yokukhipha, i-cooling roller, iyunithi yokudonsa kanye ne-turnover double position winder.Uma impendulo yesifaki khodi yamukelwa kudivayisi yokudlulisela, ukunemba kokuqina kwesivinini kungafinyelela ku-0.1%.I-Speed controand pressure controshalbe yenzeke kudivayisi yokudlulisela ye-extruder.Ukunemba okuphezulu kokudlulisela kuyadingeka ku-extruder eyinhloko kanye ne-roller yokupholisa,
3. ukuqinisekisa ukufana kwe-longitudinatolerance ye-PET sheet.Amaroli antantayo noma izinzwa ze-tension zisetshenziselwa ukuxhumana kwejubane phakathi kwama-rolcalender amathathu nogandaganda.
4. ukumiswa kwesivinini kusuka kurola okupholisa kuya kuyunithi yokudonsa kukubudlelwane beketango lejubane ukuze kuqinisekiswe ukuthi isivinini esiqondile somugqa wokukhiqiza siyadidiyelwa, futhi isivinini somugqa womugqa wokukhiqiza singanikezwa i-roller yokupholisa ngokusho ukucaciswa komkhiqizo, futhi kungasethwa ngokuzenzakalelayo.
Isistimu yokumpompa i-vacuum ezimbili × 7.5kw isethi engu-1 (isakhiwo sangaphandle) iphampu ye-vacuum: impompo ye-vacuum yeringi yamanzi + impompo yezimpande, amandla angu-5.5 + 7.5kW;
Ithangi lokujiya i-vacuum: ithange lokuhlukanisa elijiya i-stainless steevacuum, elifakwe igridi yamanzi yesihlungi sepuleti lombhoshongo ukuze kube lula ukuhluzwa kokungcola nokuguquguquka.
Isakhiwo esinezigaba ezimbili sethangi lokujiya i-vacuum singaphazamisa ngokuzenzakalelayo ukukhishwa kwamanzi, izinto eziguquguqukayo kanye nemfucuza.Idigri ye-vacuum ngeke ithinteke ngesikhathi senqubo yokukhipha.
