Iiprosesa ezingakumbi nangakumbi zifuna ukuchaneka ngakumbi kwizixhobo zabo zokutya.Le yinto eyenziwa ngabanye abantu.# Inkqubo yengcebiso
I-Plastrac gravity disc feeder iye yatshintshwa ukuba iqhube kumatshini wokubumba inaliti ethe nkqo esetyenziswa yi-Weiss-Aug Surgical Products 'i-injection molding division.
Izisombululo ze-Preform ngokuyintloko zisebenza ngokukhethekileyo kwi-preforms yokubumba isitofu kwimibala eyahlukeneyo, kodwa apha isebenzisa i-Plastrac feeder ukuqinisekisa ukuchaneka kwedosi kunye nokutshintsha okukhawulezayo kumgca wayo wokubumba owolula.
I-MCNexus ye-Movacolor okwangoku iphantsi kwezilingo zabathengi emva kokuqaliswa okuthambileyo kwi-K 2016;I-low speed feeder izakuqala ukurhweba eFakuma ngo-Okthobha.
Ukunqanda ukusetyenziswa kwee-resin ezidityanisiweyo ngaphambili, iiprosesa kwezinye iimarike ziya zicela ababoneleli bezixhobo zabo zokuphatha izixhobo ukuba babonelele ngokutya okuchanekileyo - ukuya kuthi ga kwiigram zeegranules kunye nezongezo-umzekelo, ukusebenzisa i-particle enye yedayi ewayo ngumahluko. phakathi kwenxalenye elungileyo kunye neCandelo elingeyomfuneko.URoger Hultquist uthetha ngomsebenzi wezonyango wamva nje ukubonisa ingongoma yakhe.Umthengi ekuthethwa ngaye ebefuna ukondla ngokuchanekileyo iipelithi zedayi ezintathu ezisilinda kwizibuko lokubumba lomatshini wokubumba ngexesha lokuphinda lijike elimalunga nemizuzwana emi-3.
"Akufani nokutya ngeeponti ezili-100 ngeyure," utshilo u-Hultquist, umseki kunye nomongameli wentengiso kunye nokuthengisa e-Orbetron, umthengisi wezokutya, ukuxuba kunye nezixhobo zokuphatha izinto e-Hudson, eWisconsin.I-shot enye, i-particle enye ingenza umehluko omkhulu ekuchanekeni, okuye kube yingxaki enkulu kakhulu, ngakumbi kwizicelo zonyango kwaye ngokukodwa ekwenzeni iimveliso eziguquguqukayo.“
Ngamafutshane, njengoko iimfuno ze-feedrate ziyancipha, kunjalo ke iimfuno zokuchaneka.I-Orbetron, egxile kwi-pipettes yesantya esisezantsi, ilungelelanise itekhnoloji yokondla umgubo ekuqaleni eyayisetyenziswa kwishishini lamayeza kwiiplastiki.(Jonga ngoJulayi 2017 inqaku le-Hultquist: Ukuqonda iiReyithi zoMxhesho oPhantsi wokuQhubeleka kunye neeNkqubo zeBatch.)
Abathengisi bezixhobo ezininzi bajolise kwimarike ye-niche yeeprosesa abasebenzisa ukuchaneka kunye nokuguquguquka kokutya okunesantya esisezantsi ukuxuba izinto kumatshini kunye nezinye izicelo apho ngokuchanekileyo ubuninzi bufunekayo.
Kwiiprosesa zongeza izongezo kwizinga le-0.5 lb ukuya kwi-1 lb ngeyure, ukuchaneka okuphezulu akubalulekanga, kodwa njengoko le mali iyancipha, ukuchaneka kuba yinto ebalulekileyo."Kwiprojekthi yocingo kunye nekhebula apho usondla khona izinto kwi-15 g / h, kubaluleke kakhulu ukufumana ezi ngqungquthela apho kufuneka zihambe khona," kusho u-Hultquist."Ngamaxabiso aphantsi enzala, oku kuyabaluleka, ngakumbi xa kufikwa kumbala - ukuhambelana kombala wale mveliso yenye yezinto esigxila kuzo."extruder throat, inceda ukusombulula into ethethwa nguHultqvist yingxaki yeendlela ezimbini zeepellets.
“Ungayinika, kodwa xa sele inikezelwe, ngoku kufuneka uqiniseke ukuba isasazwe ngokufanelekileyo kwinkqubo yakho,” ucacise watsho uHultquist.
U-Hultqvist waphawula ukuba ngaphezu kokuchaneka, abadlali kule ndawo bafuna iqondo eliphezulu lokuguquguquka."Kwivenkile yokungunda yesiko etshintsha imibala ngokukhawuleza, mhlawumbi izihlandlo ezili-10, ezili-12, ezili-15 ngemini, kubaluleke kakhulu ukuba bayeke batshintshe imibala ngemizuzu embalwa."iyatsalwa ngaphandle kwesixhobo, ivumela abaqhubekisi ukuba batshintshe ukusuka kwesinye isondlo ukuya kwesinye njengoko umbala utshintsha.
Okwangoku i-Orbetron ibonelela ngezondla kwiisayizi ezine - i-50, i-100, i-150 kunye ne-200 series - kunye namandla ukusuka kwi-1 gram / hr ukuya kwi-800 lb / hr.Ukongeza kwipeyinti kwiimarike ezifana nocingo / intambo kunye neemveliso zonyango, u-Hultqvist waphawula, inkampani isandula ukwandisa kwishishini lezinto zokwakha, apho i-disc feeders isetyenziselwa ukondla ii-agent ezivuthelayo, iidayi ze-siding, iiprofayili kunye neepaneli, ii-agent kunye nezinye izongezo. ..
Utshintsho olukhawulezayo "yisivumelwano sethu," ucacisa uJason Christopherson, umphathi we-Preform Solutions Inc., eseSioux Falls, eMzantsi Dakota.Izisombululo zemibhobho emfutshane kunye nephakathi kunye ne-16 kunye ne-32 cavities.Oku kunqanda ukuleqa umthamo omkhulu onxulunyaniswa namanzi okanye iipreforms zebhotile zesiselo esithambileyo, ezinokuthi zibe phezulu njenge-144 okanye ngaphezulu.
"Uninzi lweeprojekthi zethu zisebenzisa idayi," utshilo uKristofferson."Yonke imihla yeveki sinokuba nemigca emibini, emithathu, emine enemibala eyahlukeneyo kunye nezongezo ezahlukeneyo kwiipreforms zethu."
Zonke ezi shades zifuna ukuhanjiswa kwedayi echanekileyo, kwaye iinjongo zenkampani ziba nzima ngakumbi, ukuya kuthi ga kwi-0.055% kwi-672g kunye ne-0.20% kwi-54g (eyokugqibela i-98.8% resin kunye ne-0.2%).% umbala).Izisombululo ze-Preform ziseshishini ukususela kwi-2002 kwaye ixesha elininzi, utshintsho lwabo olukhethiweyo oluchanekileyo lwesisombululo sokutya esichanekileyo sibe yi-Gravity Auto-Disc Feeder esuka kwi-Plastrac, Inc. esuka e-Edgemont, ePennsylvania.Inkampani ngoku ineeyunithi zePlastrac ezili-11 ezinezinye ezikwi-odolo.
Inzuzo ye-Preform Solutions esekelwe kwi-teknoloji yePlasrac yoyilo olulodwa kunye nefuthe layo ekuchanekeni.I-feeder isebenzisa i-blade, ngokusisiseko idosa i-granules ngokusika.I-feeder iwisa iipellets kwiipokethi kwi-disc kwaye i-blade ikhupha nayiphi na indawo yeepellets ezidlula ngaphaya kweepokotho.“Xa isixhobo sePlastrac sinqumla iinkozo kwaye sigudisa iipokotho apho impahla ingena phantsi kwencakuba, ichaneke kakhulu,” utshilo uChristofferson.
I-Plastrac feeders nayo ifumene ukusetyenziswa kwishishini elinxulumeneyo kunye ne-Weiss-Aug Surgical Products e-Fairfield, NJ.Ngokutsho kukaElisabeth Weissenrieder-Bennis, umalathisi wocwangciso lobuchule, amalungu adla ngokuba mancinane, adla ngokuba sisi-1 ukusa kwisi-2 okanye ngaphantsi.
NgokukaLeo Czekalsky, umphathi wokubumba, iiyunithi ezili-12 ze-Weiss-Aug Plastrac zitshintshwe ngokukodwa yiPlastrac ukuze zisebenze koomatshini bokubumba inaliti ethe nkqo yaseArburg.Iiyunithi zePlasrac zibonelela ngoomatshini abanobukhulu besahlulo ukusuka kwi-2 ukuya kwii-ounces ezi-6 kunye ne-auger diameters ukusuka kwi-16 ukuya kwi-18 mm."Ubukhulu benaliti kunye nokunyamezela okufuneka sikugcine kwezi nxalenye zingaphakathi kwewaka le-intshi," kusho uChekalsky."Kwaye ekubeni ukuphindaphindwa kunye nomthamo wenaliti kubaluleke kakhulu, akukho ndawo yokwahluka."
Ngokutsho kweChekalsky, oku kuphinda kuphindwe kunwenwe kwimibala enikezelwa yiPlastrac."Andizange ndibone enye into echanekileyo kwaye inokuthenjwa ngaphezu kwesi sixhobo," watsho uChekalsky."Iinkqubo ezininzi zifuna ukuba umntu alungelelanise kwaye ahlengahlengise xa etshintsha imilo okanye umbala, kodwa apha inkqubo ayifuni nto."
U-Weiss-Aug ukuxabisile oku kuchaneka kunye nokusebenza ngaphandle kokuphazamiseka, ngakumbi xa kunikwa imakethi esebenzela imisebenzi yayo yaseFairfield."La macandelo anomgangatho ophezulu wokujonga ngenxa yokuba asetyenziselwa utyando," kusho u-Weissenrieder-Bennis."Kukho imigangatho ecacileyo yemibala kwaye ngenene awunakuba nakho ukwahluka."
Kwi-K 2016, inkampani yaseDatshi i-Movacolor BV (ihanjiswe e-US yi-ROMAX, INC. yase-Hudson, Massachusetts) yazisa iteknoloji yayo yokutya ephantsi, i-MCNexus, ethi inokutya i-1 ukuya kwi-5 particles (jonga i-K ibonisa ingxelo ngoFebruwari 2017) .).
Isithethi seMovacolor sathi i-MCNexus okwangoku ivavanywa ngabathengi abaninzi baseYurophu abayisebenzisayo ukuhambisa ngokuchanekileyo amanani amancinci edayi kwizinto zokudlala kunye neemveliso zasekhaya.I-Movacolor iya kubonisa i-MCNexus kwi-Fakuma 2017 eFriedrichshafen, eJamani ngo-Oktobha, iphinda iphawule ukuqaliswa kwayo ngokusemthethweni kwezorhwebo.
Uninzi lwezibumbi zisebenzisa izicwangciso ezimbini ukuseta uxinzelelo lwenqanaba lesibini.Kodwa i-Scientific Molding ine-4.
Ngaphandle kweepolyolefins, phantse zonke ezinye iipholima zikwipolar ukuya kwinqanaba elithile kwaye ngaloo ndlela zinokufunxa ukufuma okuthile emoyeni.Nazi ezinye zezi zixhobo kunye nento ekufuneka uyenzile ukuze zomise.
