Ukwakhiwa kwe-plastic extruder

Umsingathi we-plastic extruder yi-extruder, equkethe i-extrusion system, isistimu yokudlulisa kanye nesistimu yokufudumeza nokupholisa.

1.isistimu ye-extrusion

Isistimu ye-extrusion ihlanganisa isikulufu, umgqomo, i-hopper, ikhanda, kanye nesikhunta. Ipulasitiki yenziwe ngepulasitiki ibe incibilike iyunifomu ngohlelo lwe-extrusion, futhi ikhishwa ngokuqhubekayo ngesikulufu ngaphansi kwengcindezi esungulwe kule nqubo.

⑴Isikulufu: Ingxenye ebaluleke kakhulu ye-extruder, ehlobene ngokuqondile nebanga lohlelo lokusebenza kanye nokukhiqiza kwe-extruder, futhi yenziwe ngensimbi enamandla amakhulu kanye ne-alloy resistant corrosion.

⑵Isilinda: Iyisilinda sensimbi, ngokuvamile esakhiwe ngezinto ezingashisi, amandla acindezelayo aphezulu, ukumelana ngokuqinile nokubola, ingxubevange yensimbi engagqwali noma ipayipi lensimbi eliyinhlanganisela elihlanganiswe nensimbi yengxubevange. Umphongolo usebenzisana nesikulufu ukuze ubone ukuchotshozwa, ukuthambisa, ukuncibilika, ukwenziwa kwepulasitiki, ukukhathala nokuhlanganisa ipulasitiki, futhi ngokuqhubekayo nangokufanayo uhambise irabha ohlelweni lokubumba. Ngokuvamile, ubude bomphongolo buphindwe izikhathi ezingu-15 kuya kwezingu-30 ububanzi, ukuze ipulasitiki ikwazi ukushisisa ngokugcwele futhi yenziwe ngepulasitiki njengesimiso.

(3) I-Hopper: Umshini wokusika ufakwa ngaphansi kwe-hopper ukuze ulungise futhi unqamule ukuhamba kwezinto. Uhlangothi lwe-hopper lufakwe imbobo yokubuka kanye nedivayisi yokulinganisa ukulinganisa.

⑷ Ikhanda lomshini nesikhunta: Ikhanda lomshini lakhiwe ngomkhono wangaphakathi wensimbi ye-alloy kanye nomkhono wangaphandle wensimbi ye-carbon. Kukhona isikhunta esakhayo ngaphakathi kwekhanda lomshini. Setha, futhi unikeze ipulasitiki ingcindezi yokubumba edingekayo. Ipulasitiki yenziwe ngepulasitiki futhi ihlanganiswe emgqonyeni womshini, futhi igeleza ingene ekubumbeni kwekhanda lomshini ngepuleti lokuhlunga elinezimbotshana eduze kwesiteshi esithile sokugeleza entanyeni yekhanda lomshini. Isembozo se-tubular esiminyene esiqhubekayo sakhiwa eduze kwentambo ewumgogodla. Ukuze uqinisekise ukuthi indlela yokugeleza kwepulasitiki ekhanda lomshini inengqondo futhi isuse i-angle efile yepulasitiki eqoqiwe, umkhono we-shunt uvame ukufakwa. Ukuze kuqedwe ukushintshashintsha kwengcindezi ngesikhathi se-plastic extrusion, indandatho yokulinganisa ingcindezi nayo ifakiwe. Kukhona futhi idivayisi yokulungiswa kwesikhunta kanye nokulungiswa kwekhanda lomshini, elilungele ukulungisa nokulungisa ukugxila kwe-mold core kanye nomkhono wesikhunta.

Ngokuya nge-engeli ephakathi kwesiqondiso sokugeleza kwekhanda kanye nomugqa omaphakathi wesikulufu, i-extruder ihlukanisa ikhanda libe yikhanda eligobekile (i-engeli efakiwe engu-120o) kanye nekhanda elibheke kwesokudla. Igobolondo lekhanda lomshini ligxilwe emzimbeni womshini ngamabholithi. Isikhunta esingaphakathi kwekhanda lomshini sinesihlalo esiwumgogodla futhi sigxilwe embobeni yokungena yekhanda lomshini ngenadi. Ingaphambili lesihlalo esiwumgogodla ifakwe core, core kanye isihlalo core Kukhona imbobo enkabeni yokudlulisa ucingo core, futhi indandatho yokulinganisa ingcindezi ifakwe phambi kwekhanda lomshini ukulinganisa ingcindezi. Ingxenye yokubumba i-extrusion yenziwe ngesihlalo somkhono wokufa kanye nomkhono wokufa. Isikhundla somkhono wokufa singalungiswa ngebhawodi ngokusebenzisa ukusekelwa. , ukulungisa isikhundla esihlobene somkhono wesikhunta kumgogodla wesikhunta, ukuze ulungise ukufana kokuqina kwe-cladding extruded, futhi ngaphandle kwekhanda kufakwe idivayisi yokushisa kanye nedivayisi yokulinganisa izinga lokushisa.

2.isistimu yokudlulisela

Umsebenzi wesistimu yokudlulisa ukushayela isikulufu nokunikezela ngetorque nesivinini esidingwa isikulufu ngesikhathi senqubo yokukhipha. Ngokuvamile yakhiwa injini, i-reducer kanye ne-bearing.

Ngokwesisekelo sokuthi isakhiwo siyefana ngokuyisisekelo, izindleko zokukhiqiza zesinciphisi zicishe zilingane nosayizi nesisindo saso sisonke. Ngenxa yokuthi ukwakheka nesisindo sokunciphisa kukhulu, kusho ukuthi izinto eziningi ezisetshenziswayo zisetshenziswa ngesikhathi sokukhiqiza, futhi ama-bearings asetshenzisiwe nawo akhulu kakhulu, okwandisa izindleko zokukhiqiza.

Kuma-extruder ane-screw diameter efanayo, ama-extruder anesivinini esiphezulu futhi asebenza kahle kakhulu adla amandla amaningi kunama-extruder avamile, amandla emoto aphindwe kabili, futhi usayizi wefreyimu yesinciphisi uyakhula ngokufanayo. Kodwa isivinini esikhulu sesikulufa sisho isilinganiso esiphansi sokunciphisa. Ngokunciphisa usayizi ofanayo, i-modulus yegiya yesilinganiso esiphansi sokunciphisa inkulu kunaleyo yesilinganiso esikhulu sokunciphisa, futhi umthamo wokuthwala umthwalo wesinciphisi nawo uyakhuphuka. Ngakho-ke, ukukhuphuka kwevolumu nesisindo sokunciphisa akulingani ngokulinganayo nokwanda kwamandla emoto. Uma ivolumu ye-extrusion isetshenziswa njenge-denominator futhi ihlukaniswa nesisindo sokunciphisa, inani lama-extruder anesivinini esiphezulu nelisebenza kahle lincane, futhi inani lama-extruder ajwayelekile likhulu.

Ngokuphathelene nokuphuma kweyunithi, amandla emoto we-extruder enesivinini esikhulu futhi esebenza kahle kakhulu mancane futhi isisindo sesinciphisi sincane, okusho ukuthi izindleko zokukhiqiza iyunithi ye-extruder enesivinini esikhulu futhi esebenza kahle kakhulu iphansi kune lokho kwama-extruder ajwayelekile.

3.idivayisi yokushisisa nokupholisa

Ukushisa nokupholisa yizimo ezidingekayo ukuze inqubo ye-plastic extrusion isebenze.

⑴I-extruder ivamise ukusebenzisa ukushisisa kukagesi, okuhlukaniswa ngokushisa kokumelana nokushisisa okungeniswayo. Ishidi lokushisa lifakwe engxenyeni ngayinye ye-fuselage, intamo yomshini kanye nekhanda lomshini. Idivayisi yokushisisa ishisisa ipulasitiki kusilinda ngaphandle ukuze ishise ifike ezingeni lokushisa elidingekayo ekusebenzeni kwenqubo.

(2) Umshini wokupholisa usethelwe ukuqinisekisa ukuthi ipulasitiki isezingeni lokushisa elidingwa inqubo. Ngokukhethekile, okokuqeda ukushisa okudlulele okukhiqizwa ukungqubuzana kwe-shear kokuzungezisa isikulufu, ukuze kugwenywe ukubola kwepulasitiki, ukushisisa noma ubunzima bokubunjwa ngenxa yezinga lokushisa elidlulele. Kunezinhlobo ezimbili zokupholisa umgqomo: ukupholisa amanzi nokupholisa umoya. Ngokuvamile, ukupholisa komoya kufaneleka kakhulu kuma-extruder amancane naphakathi nendawo, futhi ukupholisa amanzi noma inhlanganisela yezinhlobo ezimbili zokupholisa kuvame ukusetshenziselwa ama-extruder amakhulu. Ukupholisa isikulufu ikakhulukazi kusebenzisa ukupholisa kwamanzi okumaphakathi ukuze kukhuphule izinga lokulethwa okuqinile kwezinto. , uzinzise ukuphuma kweglue, futhi uthuthukise ikhwalithi yomkhiqizo ngesikhathi esifanayo; kodwa ukupholisa ku-hopper ukuqinisa umphumela wokudlulisa ezintweni eziqinile futhi uvimbele izinhlayiya zepulasitiki ukuthi zinganamatheli ngenxa yokukhuphuka kwezinga lokushisa futhi uvimbele imbobo yokuphakelayo, futhi okwesibili ukuqinisekisa ukusebenza okuvamile kwengxenye yokudlulisela.
