Iyo Plastrac gravity disc feeder yakagadziridzwa kuti imhanye pamajekiseni ekuumba majekiseni anoshandiswa neWeiss-Aug Kuvhiya Zvigadzirwa 'jekiseni rekuumba kupatsanurwa.
Preform Solutions inonyanya kuita majekiseni ekuumba mapreforms mumhando dzakasiyana siyana, asi pano inoshandisa Plastrac feeders kuve nechokwadi chedosing chokwadi uye nekukurumidza shanduko pamutsetse wayo wakatambanudzwa wekuumba.
Movacolor's MCNexus parizvino irikuedzwa nevatengi mushure mekutanga kunyorova paK 2016;The low speed feeder ichaita bhizimusi rayo rekutanga paFakuma muna Gumiguru.
Kuti udzivise kushandiswa kwe pre-yakasanganiswa resin, ma processor mune mamwe misika ari kuramba achikumbira vatengesi vemidziyo yekubata zvinhu kuti vape kunyatso dyisa - kusvika magiramu emagranules ega ega uye zvinowedzera - semuenzaniso, kuisa dhayi imwe inodonha ndiyo mutsauko. pakati pechikamu chakanaka uye chikamu chisingadikanwi.Roger Hultquist anotaura nezvebasa rekurapa richangoburwa kuratidza pfungwa yake.Mutengi ari mubvunzo aida kunyatsodyisa mapellet matatu edhayi mumajekiseni ekuumba muchina wekudya mukati menguva yekudzoreredza screw ingangoita masekonzi matatu.
"Hazvina kufanana nekudya pamapaunzi zana paawa," anodaro Hultquist, mubatsiri uye purezidhendi wekutengesa nekushambadzira kuOrbetron, mutengesi wezvekudya, kusanganisa uye zvekushandisa muHudson, Wisconsin.Kupfura kamwe chete, chidimbu chimwe chete chinogona kuita mutsauko mukuru mukurongeka, iro riri kuita dambudziko rakakura, kunyanya mumashandisirwo ekurapa uye kunyanya mukugadzirwa kwezvinhu zvinopenya.“
Muchidimbu, sezvo zvinodiwa zve feedrate zvinodzikira, ndizvo zvinoitawo kurongeka zvinodiwa.Orbetron, iyo inonyanya kumhanyisa mapipettes, yakagadzirisa tekinoroji yekudyisa hupfu yakatanga kushandiswa muindasitiri yemishonga kumapurasitiki.(Ona Chikunguru 2017 Hultquist chinyorwa: Kunzwisisa Yakaderera Feed Matengo eInoenderera uye Batch Maitiro.)
Vatengesi vemidziyo vakati wandei vakananga kumusika niche wema processors vanoshandisa iko kurongeka uye kuchinjika kweyakaderera yekumhanyisa mafeed kusanganisa zvinhu mumakina uye mamwe maapplication panodiwa kurongeka chaiko.
Kune ma processors anowedzera zvinowedzera pamwero we 0.5 lb kusvika 1 lb paawa, kurongeka kwepamusoro hakukoshi, asi sezvo huwandu uhu huchiderera, kurongeka kunova kwakakosha."Muchirongwa chewaya netambo kwauri kudyisa zvinhu pa15 g/h, zvakakosha kuti utore zvimedu izvi chaiko kwadzinoda kuenda," Hultquist akadaro."Pamitengo yakaderera yemubereko, izvi zvinova zvakakosha, kunyanya kana zvasvika kune ruvara - kuenderana kwemavara echigadzirwa ichi ndechimwe chezvinhu zvatinotarisa."extruder huro, kubatsira kugadzirisa zvinotaurwa naHultqvist idambudziko renzira mbiri dzepellets.
"Unogona kuishandisa, asi kana yapihwa, unofanirwa kuve nechokwadi kuti yagovaniswa nenzira yako," Hultquist akatsanangura.
Hultqvist akacherekedza kuti pamusoro pekurongeka, vatambi munzvimbo ino vanodawo mwero wepamusoro wekushanduka."Kune chitoro chekugadzira mold chinochinja mavara nekukurumidza, pamwe 10, 12, ka15 pazuva, zvinova zvakakosha kuti vamire uye kuchinja mavara mumaminetsi mashoma."inoburitswa kunze kwemudziyo, ichibvumira processors kuti ichinje kubva kune imwe feeder kuenda kune imwe sezvo ruvara ruchichinja.
Orbetron parizvino inopa mafeeders mumasaizi mana - iyo 50, 100, 150 uye mazana maviri akatevedzana - ane hunyanzvi kubva pa1 giramu/hr kusvika 800 lb/hr.Pamusoro pekupenda mumisika yakaita sewaya/tambo uye zvigadzirwa zvekurapa, Hultqvist akacherekedza, kambani ichangobva kuwedzera muindasitiri yezvivakwa zvekuvaka, uko madhishi edhisiki anoshandiswa kudyisa maajenti anofuridza, siding dhayi, profiles uye mapaneru, vamiririri nezvimwe zvinowedzera. ..
Kuchinja kwekukurumidza "chibvumirano chedu," anotsanangura kudaro Jason Christopherson, maneja wePreform Solutions Inc., ari muSioux Falls, South Dakota.Mhinduro dzenguva pfupi uye dzepakati dze mold dzine 16 uye 32 cavities.Izvi zvinodzivirira iyo yakakura vhoriyamu kudzingirira kwakabatana nemvura kana zvinwiwa bhodhoro preforms, iyo inogona kunge yakakwira se144 kana kupfuura.
"Mapurojekiti edu mazhinji anoshandisa dhayi," anodaro Kristofferson."Zuva rega rega revhiki tinogona kuva nemitsara miviri, mitatu, mina ine mavara akasiyana uye akasiyana ekuwedzera kune yedu preform."
Zvose izvi mimvuri zvinoda kuendeswa kwedhayi kwakaringana, uye zvinangwa zvekambani zviri kuwedzera kuoma, kusvika pa0.055% pa672g uye 0.20% pa54g (iyo yekupedzisira iri 98.8% resin uye 0.2%).% ruvara).Preform Solutions yave iri mubhizinesi kubvira 2002 uye kwenguva yakawanda yenguva iyoyo, yavo yavanoda kukurumidza shanduko chaiyo yekudyisa mhinduro yanga iri Gravity Auto-Disc Feeder kubva kuPlastrac, Inc. kubva kuEdgemont, Pennsylvania.Iyo kambani parizvino ine gumi nerimwe Plastrac mayunitsi ane mamwe mana pakuraira.
Iyo mukana wePreform Solutions yakavakirwa paPlasrac tekinoroji ndiyo yakasarudzika dhizaini uye maitiro ayo pakurongeka.Iyo yekudyisa inoshandisa blade, kunyanya dosing granules nekucheka.Iyo yekudyisa inodonhedza mapellets muhomwe padhisiki uye blade inokwenya chero chikamu chemapellets chinopfuurira mberi kwehomwe.“Apo mudziyo wePlastrac ukacheka patsanga uye wotsvedzerera homwe panopinda zvinhu pasi pebadza, zvinenge zvakanyatsorurama,” Christofferson akadaro.
Plastrac feeders vakawanawo kushandiswa mune yakabatana indasitiri neWeiss-Aug Kuvhiya Zvigadzirwa muFairfield, NJ.Maererano naElisabeth Weissenrieder-Bennis, mutungamiriri wezvekuronga zvirongwa, zvikamu zvinowanzova zviduku, kazhinji 1 kusvika ku2 kana kuti zvishoma.
Sekureva kwaLeo Czekalsky, maneja wekuumbwa, gumi nemaviri Weiss-Aug Plastrac zvikamu zvakagadziridzwa zvakanyanya nePlastrac kuti ishande paArburg's vertical jekiseni rekuumba michina.Plasrac zvikamu zvinopa michina ine zvikamu saizi kubva pa2 kusvika pa6 ounces uye auger madhayamita kubva pa16 kusvika 18 mm."Majekiseni emajekiseni uye kushivirira kwatinofanira kuchengeta kune zvikamu izvi zviri mukati mezviuru zve inch," akadaro Chekalsky."Uye sezvo kudzokorora uye vhoriyamu yejekiseni yakakosha, hapana nzvimbo yekusiyana."
Maererano naChekalsky, kudzokorora uku kunowedzera kune mavara anopiwa nePlastrac."Handisati ndamboona chimwe chinhu chakarurama uye chakavimbika kupfuura chigadzirwa ichi," akadaro Chekalsky."Mamwe masisitimu mazhinji anoda kuti mumwe munhu agadzirise uye agadzirise kana achichinja chimiro kana ruvara, asi pano system yacho haidi chero chinhu."
Weiss-Aug akatenda kurongeka uye kushanda-kwemahara, kunyanya kupihwa musika unoshandira Fairfield mashandiro ayo."Izvi zvikamu zvine chimiro chepamusoro chekuona nekuti chinoshandiswa pakuvhiya," akadaro Weissenrieder-Bennis."Kune chaiwo mavara akajairwa uye haugone kuve nemusiyano."
PaK 2016, kambani yeDutch Movacolor BV (yakagoverwa muUS neROMAX, INC. yeHudson, Massachusetts) yakaunza yayo yakaderera feed tekinoroji, MCNexus, iyo inoti inogona kudyisa 1 kusvika ku5 particles (ona K show report yaFebruary 2017) .)
Mutauriri weMovacolor akataura kuti MCNexus parizvino iri kuedzwa nevatengi vakati wandei muEurope vanoishandisa kuburitsa nemazvo mashoma madhayi mumatoyi uye zvigadzirwa zvemumba.Movacolor ichaunza MCNexus paFakuma 2017 muFriedrichshafen, Germany muna Gumiguru, zvakare ichicherekedza kutanga kwayo kutengeserana kwepamutemo.
