Amaphrosesa andayo adinga ukunemba okwengeziwe kumishini yabo yokuphakelayo.Yilokhu okwenziwa abanye abantu.#Inqubo yokusikisela
I-Plastrac gravity disc feeder ishintshiwe ukuze isebenze emshinini wokubumba umjovo oqondile osetshenziswa isigaba sokubumba umjovo we-Weiss-Aug Surgical Products'.
I-Preform Solutions igxile kakhulu ekubumbeni umjovo okwenziwe ngokwezifiso ngemibala ehlukahlukene, kodwa lapha isebenzisa iziphakeli ze-Plastrac ukuze kuqinisekiswe ukunemba komthamo kanye noshintsho olusheshayo emugqeni wayo wokubumba owunwebekayo.
I-MCNexus ye-Movacolor okwamanje ibhekene nezivivinyo zamakhasimende ngemva kokwethulwa okuthambile ngo-K 2016;I-low-speed feeder izoqala ukudayisa eFakuma ngo-Okthoba.
Ukuze ugweme ukusetshenziswa kwama-resin ahlanganiswe ngaphambili, amaphrosesa kwezinye izimakethe aya ngokuya ecela abahlinzeki babo bemishini yokuphatha impahla ukuthi banikeze ukuphakelwa okunembe kakhudlwana - kuze kufike kumagremu ezinhlayiyana ngazinye nezithasiselo - ngokwesibonelo, ukusebenzisa inhlayiya eyodwa kadayi ewayo kungumehluko. phakathi kwengxenye enhle nengxenye engadingekile.URoger Hultquist ukhuluma ngomsebenzi wezokwelapha wakamuva ukuze aveze iphuzu lakhe.Ikhasimende okukhulunywa ngalo belifuna ukondla ngokunembile amapellets amathathu kadayi ayisilinda embobeni yokuphakelayo yomshini wokubumba umjovo phakathi nesikhathi sokuphinda sithole isikulufu esingamasekhondi angu-3.
“Akufani nokudla ngamaphawundi ayi-100 ngehora,” kusho u-Hultquist, umsunguli kanye nomongameli wezokuthengisa nokumaketha e-Orbetron, umphakeli wezinto eziphakelayo, ezixutshwayo nezokuphatha izinto ezibonakalayo e-Hudson, Wisconsin.Ukudubula okukodwa, inhlayiya eyodwa kungenza umehluko omkhulu ekunembeni, okuba inkinga enkulu kakhulu, ikakhulukazi ezinhlelweni zezokwelapha futhi ikakhulukazi ekwenziweni kwemikhiqizo ekhanyayo.“
Ngamafuphi, njengoba izidingo ze-feedrate zincipha, nezidingo zokunemba ziyanda.I-Orbetron, egxile kakhulu kumapayipi anejubane eliphansi, iguqule ubuchwepheshe bokuphakela impushana obusetshenziswa ekuqaleni embonini yezemithi baba ngamapulasitiki.(Bona i-athikili ye-Hultquist kaJulayi 2017: Ukuqonda Amanani Okuphakelayo Okuphansi Ngezinqubo Eziqhubekayo Nenqwaba.)
Abathengisi bemishini abaningana baqondise imakethe ye-niche yamaphrosesa abasebenzisa ukunemba nokuguquguquka kokuphakelayo kwesivinini esiphansi ukuxuba izinto emishinini nakwezinye izinhlelo zokusebenza lapho kudingeka khona ukunemba okuphezulu.
Kumaphrosesa anezela izithasiselo ngesilinganiso esingu-0.5 lb kuya ku-1 lb ngehora, ukunemba okuphezulu akubalulekile, kodwa njengoba leli nani lincipha, ukunemba kuba okubucayi."Kuphrojekthi yocingo nekhebula lapho uphakela khona izinto ngo-15 g/h, kubaluleke kakhulu ukuthola lezi zinhlayiya lapho zidinga ukuya khona," kusho u-Hultquist."Ngezilinganiso zenzalo ephansi, lokhu kuba bucayi, ikakhulukazi uma kuziwa embaleni - ukungaguquguquki kombala walo mkhiqizo kungenye yezinto esigxila kuzo."i-extruder throat, esiza ukuxazulula okushiwo u-Hultqvist kuyinkinga yezindlela ezimbili zama-pellets.
"Ungayinikeza, kodwa uma isikhishiwe, manje kufanele uqiniseke ukuthi isatshalaliswe ngendlela efanele ohlelweni lwakho," kuchaza u-Hultquist.
U-Hultqvist uphawule ukuthi ngaphezu kokunemba, abadlali kule ndawo badinga nezinga eliphezulu lokuguquguquka."Esitolo sokubumba esishintsha imibala ngokushesha, mhlawumbe izikhathi ezingu-10, 12, 15 ngosuku, kubaluleke kakhulu ukuthi bame futhi bashintshe imibala ngemizuzu embalwa."ikhishwa kudivayisi, okuvumela amaphrosesa ukuthi ashintshe asuke kokuphakelayo aye kwesinye njengoba umbala ushintsha.
Njengamanje i-Orbetron ihlinzeka ngokuphakelayo ngosayizi abane - uchungechunge lwama-50, 100, 150 kanye no-200 - olunamandla asukela ku-1 gram/hr kuya ku-800 lb/hr.Ngaphezu kokudweba ezimakethe ezifana nocingo/ikhebula kanye nemikhiqizo yezokwelapha, u-Hultqvist waphawula, inkampani isanda kunwetshwa embonini yezinto zokwakha, lapho ama-disc feeders asetshenziselwa ukondla ama-ejenti afuthayo, odayi baseceleni, amaphrofayili namaphaneli, ama-ejenti nezinye izithasiselo. ..
Ukushintsha okusheshayo “kuyisivumelwano sethu,” kuchaza uJason Christopherson, umphathi we-Preform Solutions Inc., ozinze eSioux Falls, eNingizimu Dakota.Izixazululo zesikhunta esifushane nesimaphakathi esinama-cavities angu-16 nama-32.Lokhu kugwema ukujaha ivolumu enkulu okuhlobene namanzi noma amabhodlela eziphuzo ezithambile, okungaba phezulu njengokungu-144 noma ngaphezulu.
"Amaphrojekthi ethu amaningi asebenzisa odayi," kusho uKristofferson.“Njalo ngosuku lwesonto singaba nemigqa emibili, emithathu, emine enemibala ehlukene kanye nezithasiselo ezihlukene zama-preforms ethu.”
Yonke le mithunzi idinga ukulethwa okunembile kodayi, futhi okuhloswe yinkampani kuya ngokuya kuba nzima, kuze kufike ku-0.055% ku-672g no-0.20% ku-54g (okugcina kungu-98.8% resin no-0.2%).% umbala).I-Preform Solutions ibe sebhizinisini kusukela ngo-2002 futhi isikhathi esiningi, isisombululo sabo sokudla esisheshayo esishintshayo kube yi-Gravity Auto-Disc Feeder evela ku-Plastrac, Inc. yase-Edgemont, e-Pennsylvania.Njengamanje inkampani inamayunithi ePlastrac angu-11 namanye amane ahleliwe.
Inzuzo ye-Preform Solutions esekelwe kubuchwepheshe be-Plasrac umklamo oyingqayizivele nomthelela wawo ekunembeni.I-feeder isebenzisa i-blade, empeleni idonsa ama-granules ngokusika.I-feeder iwisa ama-pellets emaphaketheni ku-disc futhi i-blade ikhipha noma iyiphi ingxenye yama-pellets edlula ngaphezu kwamaphakethe.“Lapho umshini wePlastrac usika izinhlamvu bese ushelela amaphakethe lapho impahla ingena ngaphansi kwensingo, inemba kakhulu,” kusho uChristofferson.
Abaphakeli be-Plastrac nabo bathole ukusetshenziswa embonini ehlobene ne-Weiss-Aug Surgical Products e-Fairfield, NJ.Ngokuka-Elisabeth Weissenrieder-Bennis, umqondisi wokuhlela amasu, izingxenye ngokuvamile ziba zincane, ngokuvamile zingu-1 kuya ku-2 noma ngaphansi.
Ngokuka-Leo Czekalsky, umphathi wokubumba, amayunithi angu-12 e-Weiss-Aug Plastrac ashintshwe ngokukhethekile yi-Plastrac ukuze asebenze emishinini yokubumba imijovo eqondile yase-Arburg.Amayunithi e-Plasrac ahlinzeka ngemishini enosayizi bezingxenye ukusuka kuma-ounces angu-2 ukuya kwangu-6 kanye namadiamitha e-auger ukusuka ku-16 kuya ku-18 mm."Ubukhulu bomjovo kanye nokubekezelelana okufanele sikugcine kulezi zingxenye kungaphakathi kwezinkulungwane zama-intshi," kusho u-Chekalsky."Futhi njengoba ukuphindaphinda kanye nevolumu yomjovo kubaluleke kakhulu, asikho isikhala sokuhlukahluka."
Ngokusho kukaChekalsky, lokhu kuphindaphinda kudlulela emibaleni enikezwa yiPlastrac."Angikaze ngibone lutho olunembe kakhulu futhi oluthembekile kunalolu hlelo," kusho uChekalsky."Ezinye izinhlelo eziningi zidinga umuntu ukuthi alinganise futhi alungise lapho eshintsha isimo noma umbala, kodwa lapha uhlelo aludingi lutho."
U-Weiss-Aug ukujabulele lokhu kunemba nokusebenza okungenazinkinga, ikakhulukazi uma kubhekwa imakethe ehlinzeka ngemisebenzi yayo yase-Fairfield.“Lezi zingxenye zinezinga eliphezulu elibonakalayo ngenxa yokuthi zisetshenziswa ekuhlinzeni,” kusho u-Weissenrieder-Bennis."Kunamazinga akhethekile emibala futhi awunakuba nakho ukuhluka."
Ku-K ​​2016, inkampani yaseDutch i-Movacolor BV (esatshalaliswa e-US yi-ROMAX, INC. yase-Hudson, Massachusetts) yethula ubuchwepheshe bayo bokuphakelayo obuphansi, i-MCNexus, ethi ingaphakela izinhlayiya ezi-1 kuye kwezingu-5 (bona umbiko wombukiso we-K wangoFebhuwari 2017) .).
Umkhulumeli we-Movacolor uthe i-MCNexus okwamanje ihlolwa amakhasimende ambalwa ase-Europe ayisebenzisayo ukuze akhiphe ngokunembile amanani amancane odayi kumathoyizi nemikhiqizo yasendlini.I-Movacolor izokwethula i-MCNexus ku-Fakuma 2017 e-Friedrichshafen, e-Germany ngo-Okthoba, futhi imaka ukwethulwa kwayo okusemthethweni kwezohwebo.
Izibunzi eziningi zisebenzisa izilungiselelo ezimbili ukusetha ingcindezi yesigaba sesibili.Kodwa iScientific Molding inezine.
