Ukuqulunqwa kwe-extruder yeplastiki

Umninimzi we-plastic extruder yi-extruder, equkethe inkqubo yokukhupha, inkqubo yokuhambisa kunye nenkqubo yokufudumala kunye nokupholisa.

Inkqubo ye-1.extrusion

Inkqubo ye-extrusion ibandakanya i-screw, i-barrel, i-hopper, intloko, kunye ne-mold. Iplastiki ifakwe kwiplastiki kwi-uniform inyibilika nge-extrusion system, kwaye ngokuqhubekayo ikhutshwe nge-screw phantsi koxinzelelo olusekwe kwinkqubo.

⑴Isikruru: Yeyona nxalenye ibalulekileyo ye-extruder, ehambelana ngokuthe ngqo kuluhlu lwesicelo kunye nemveliso ye-extruder, kwaye yenziwe ngentsimbi ephezulu kunye ne-corrosion-resistant alloy.

⑵Isilinda: Yisilinda yesinyithi, eyenziwe ngokubanzi ngokumelana nobushushu, amandla acinezelayo aphezulu, ukumelana nokungagugi, intsimbi enganyangekiyo kwi-alloy okanye umbhobho wentsimbi odibeneyo ofakwe ngentsimbi yealloy. Umgqomo usebenzisana ne-screw ukuqonda ukutyumza, ukuthambisa, ukunyibilika, ukuxutywa kweplastiki, ukuphelelwa amandla kunye nokudibanisa iplastiki, kwaye ngokuqhubekayo nangokufanayo ukuhambisa irabha kwinkqubo yokubumba. Ngokuqhelekileyo, ubude bombhobho buphindwe ngama-15 ukuya kuma-30 ububanzi bayo, ukuze iplastiki ikwazi ukufudumeza ngokupheleleyo kwaye ifakwe iplastiki njengomgaqo.

(3) I-Hopper: Isixhobo esinqunyiweyo sifakwe ezantsi kwe-hopper ukulungisa kunye nokunqumla ukuhamba kwezinto. Icala le-hopper lixhotyiswe ngomngxuma wokujonga kunye nesixhobo sokulinganisa i-calibration.

⑷ Intloko yomatshini kunye nokubumba: Intloko yomatshini yenziwe nge-alloy steel sleeve yangaphakathi kunye ne-carbon steel sleeve yangaphandle. Kukho ukubumba okubumba ngaphakathi kwentloko yomatshini. Seta, kwaye unike iplastiki uxinzelelo oluyimfuneko lokubumba. Iplastiki yenziwe ngeplastiki kwaye idityaniswe kumbhobho womatshini, kwaye iqukuqela ukuya kubumba lokubumba intloko yomatshini ngepleyiti yokucoca enemingxuma ecaleni komjelo othile wokuqukuqela entanyeni yentloko yomatshini. Isigqubuthelo esixineneyo se-tubular senziwa malunga nocingo olungundoqo. Ukuze kuqinisekiswe ukuba indlela yokuhamba kweplastiki kwintloko yomatshini inengqiqo kwaye ikhuphe i-angle efileyo yeplastiki eqokelelweyo, i-shunt sleeve ivame ukufakwa. Ukuze kupheliswe ukuguquguquka koxinzelelo ngexesha lokukhupha iplastiki, indandatho yokulinganisa uxinzelelo nayo ifakiwe. Kukho kwakhona ukulungiswa kwesikhunta kunye nesixhobo sokulungelelanisa kwintloko yomatshini, ekulungele ukulungelelanisa kunye nokulungiswa kwe-concentricity ye-mold core kunye ne-sleeve yokubumba.

Ngokwe-engile phakathi kolwalathiso lokuhamba kwentloko kunye nomgca ophakathi we-screw, i-extruder yahlula intloko ibe yintloko ye-beveled (i-120o ibandakanya i-angle) kunye nentloko echanekileyo. Igobolondo lentloko yomatshini igxininiswe kumzimba womatshini ngeebholiti. Isikhunta ngaphakathi kwentloko yomatshini sinesihlalo esingundoqo kwaye sigxininise kwi-port yokungena yentloko yomatshini kunye ne-nut. Umphambili wesihlalo esiphambili uxhotyiswe ngondoqo, isiseko kunye nesitulo esiphambili Kukho umngxuma kwiziko lokudlula ucingo oluphambili, kwaye indandatho yokulinganisa uxinzelelo ifakwe phambi kwentloko yomatshini ukulinganisa uxinzelelo. Inxalenye yokubumba i-extrusion yenziwe sisitulo somkhono wokufa kunye nomkhono wokufa. Isikhundla somkhono wokufa sinokulungiswa ngebholi ngokusebenzisa inkxaso. , ukulungelelanisa indawo ehambelana nomkhono wokubumba kwi-mold core, ukwenzela ukuba ulungelelanise ukufana kobunzima be-cladding extruded, kwaye ngaphandle kwentloko ixhotywe ngesixhobo sokufudumala kunye nesixhobo sokulinganisa ubushushu.

2.inkqubo yothumelo

Umsebenzi wenkqubo yokuhanjiswa kukuqhuba i-screw kunye nokubonelela nge-torque kunye nesantya esifunwa yi-screw ngexesha lenkqubo yokukhupha. Ngokuqhelekileyo iqulunqwe yi-motor, i-reducer kunye ne-bearing.

Kwisiseko sokuba ulwakhiwo luyafana, iindleko zokwenziwa komnciphisi ziphantse zilingane nobukhulu bayo bubonke kunye nobunzima. Ngenxa yokuba imilo kunye nobunzima bomnciphisi bukhulu, oko kuthetha ukuba izinto ezininzi zisetyenziswa ngexesha lokuvelisa, kwaye iibheringi ezisetyenzisiweyo nazo zinkulu, nto leyo eyandisa iindleko zokuvelisa.

Kwi-extruders ene-screw diameter efanayo, i-speed-speed and high-efficiency extruders idla amandla amaninzi kune-extruders eqhelekileyo, amandla emoto aphindwe kabini, kunye nobukhulu besakhelo sokunciphisa ngokuhambelanayo. Kodwa isantya esiphezulu se-screw sithetha umlinganiselo ophantsi wokunciphisa. Ngomnciphisi wobungakanani obufanayo, imodyuli yegiya yomlinganiselo ophantsi wokunciphisa inkulu kunomlinganiselo omkhulu wokunciphisa, kunye nomthamo wokuthwala umthwalo womnciphisi nawo wonyuswa. Ke ngoko, ukwanda komthamo kunye nobunzima bomnciphisi abuhambelani ngokuhambelana nokunyuka kwamandla emoto. Ukuba umthamo we-extrusion usetyenziswa njenge-denominator kwaye uhlukaniswe ngobunzima bomnciphisi, inani le-high-speed and high-efficiency extruders lincinci, kwaye inani le-extruders eziqhelekileyo likhulu.

Ngokubhekiselele kwimveliso yeyunithi, amandla emoto ye-high-speed and high-effective extruder encinci kwaye ubunzima bomnciphisi buncinci, oku kuthetha ukuba ixabiso leyunithi yokuvelisa i-extruder ephezulu kunye ne-high-effective extruder ingaphantsi kune ukuba extruders eqhelekileyo.

3.isixhobo sokufudumeza kunye nokupholisa

Ukufudumeza kunye nokupholisa ziimeko eziyimfuneko ukuze inkqubo yeplastiki ye-extrusion isebenze.

⑴I-extruder ihlala isebenzisa ukufudumeza kombane, okwahlulahlulwe kukuxhathisa ukufudumeza kunye nokufudumeza kwe-induction. Iphepha lokufudumala lifakwe kwindawo nganye ye-fuselage, intamo yomatshini kunye nentloko yomatshini. Isixhobo sokufudumeza sitshisa iplastiki kwi-cylinder ngaphandle ukufudumeza ukuya kwiqondo lokushisa elifunekayo ekusebenzeni kwenkqubo.

(2) Isixhobo sokupholisa simiselwe ukuqinisekisa ukuba iplastiki ikwiqondo lobushushu elifunwa yinkqubo. Ngokukodwa, kukuphelisa ubushushu obugqithisileyo obuveliswa kukukhuhlana kwe-shear ye-screw rotation, ukuze kuthintelwe ukubola kweplastiki, ukutshisa okanye ubunzima bokubumba ngenxa yobushushu obugqithisileyo. Kukho iindidi ezimbini zokupholisa umphanda: ukupholisa amanzi kunye nokupholisa umoya. Ngokuqhelekileyo, ukupholisa umoya kulungeleka ngakumbi kwii-extruders ezincinci kunye naphakathi, kunye nokupholisa kwamanzi okanye indibaniselwano yeentlobo ezimbini zokupholisa zihlala zisetyenziselwa ii-extruders ezinkulu. Ukupholisa isikrufu ikakhulu kusebenzisa ukupholisa kwamanzi okuphakathi ukunyusa izinga lonikezelo oluluqilima lwemathiriyeli. , ukuzinzisa imveliso yeglue, kunye nokuphucula umgangatho wemveliso ngexesha elifanayo; kodwa ukupholisa kwi-hopper kukuqinisa impembelelo yokuhambisa kwizinto eziqinileyo kunye nokuthintela amaqhekeza eplastiki ukuba abambelele ngenxa yokunyuka kweqondo lokushisa kunye nokuthintela i-port feed, kwaye okwesibini kukuqinisekisa ukusebenza okuqhelekileyo kwenxalenye yokudluliselwa.
