Iyo mauto epurasitiki extruder ndiyo extruder, iyo inosanganisira extrusion system, transmission system uye yekudziya uye kutonhora system.
1.extrusion system
Iyo extrusion system inosanganisira screw, barrel, hopper, musoro, uye mold. Plastiki inogadzirwa nepurasitiki kuita yunifomu inonyungudika kuburikidza neiyo extrusion system, uye inoramba ichibudiswa nescuru pasi pekumanikidzwa kwakagadzwa mukuita.
⑴Screw: Ndiyo inonyanya kukosha chikamu cheextruder, icho chakanangana nemhando yekushandisa uye kugadzirwa kweiyo extruder, uye inogadzirwa nepamusoro-simba uye inodzivirira-inodzivirira alloy simbi.
⑵Cylinder: Silinda yesimbi, inowanzo gadzirwa nekupisa-kupisa, kusimba kwesimba, yakasimba isingapfeki, inodzivirira kuparara kwesimbi kana pombi yesimbi inoumbwa yakamisikidzwa nesimbi yealloy. Iyo dhiramu inobatirana nescuru kuti ione kupwanya, kupfava, kunyunguduka, kuisa purasitiki, kupera simba uye kusungirirana kwepurasitiki, uye nekuenderera uye zvakafanana kutakura rabha kune inoumba system. Kazhinji, kureba kwebhodhoro ndeye 15 kusvika ku30 dhayamita yaro, kuitira kuti plastiki inogona kunyatsopisa uye plastiki semusimboti.
(3) Hopper: Chishandiso chekucheka-cheka chinoiswa pazasi pehopper kugadzirisa uye kutema kuyerera kwezvinhu. Rutivi rwehopper yakashongedzerwa negomba rekuona uye calibration metering mudziyo.
⑷ Musoro wemuchina uye mold: Musoro wemuchina unoumbwa nealloy simbi yemukati sleeve uye kabhoni simbi yekunze sleeve. Pane kuumba mold mukati memusoro wemuchina. Seta, uye upe plastiki inodiwa yekuumba kumanikidza. Plastiki inogadzirwa nepurasitiki uye yakamisikidzwa mumushini wechirongo, uye inoyerera ichipinda mukuumbwa kwemusoro wemuchina kuburikidza neiyo porous sefa ndiro pamwe neimwe nzira yekuyerera kuburikidza nemutsipa wemusoro wemuchina. Chifukidziro chinoramba chakakora tubular chinoumbwa chakatenderedza waya yepakati. Kuti uone kuti nzira yepurasitiki yekuyerera mumusoro wemuchina inonzwisisika uye kubvisa kona yakafa yepurasitiki yakaunganidzwa, shunt sleeve inowanzoiswa. Kuti ubvise kudzvinyirirwa kwekuchinja panguva yepurasitiki extrusion, mhete yekuenzanisa mhete inoiswawo. Iko kune zvakare yekugadziridza mold uye gadziriso mudziyo pamusoro wemuchina, iyo iri nyore kugadzirisa uye kugadzirisa concentricity ye mold core uye mold sleeve.
Zvinoenderana nekona pakati pekuyerera kwemusoro uye mutsara wepakati we screw, iyo extruder inokamura musoro kuita musoro wakakomberedzwa (120o inosanganisirwa kona) uye musoro-wakona. Iyo shell yemusoro wemuchina inogadziriswa pamuchina wemuviri nemabhaudhi. Iyo mold mukati memusoro wemuchina ine chigaro chepakati uye yakagadzikwa pane inopinza port yemuchina wemusoro ine nati. Pamberi pechigaro chepakati chakashongedzerwa nepakati, musimboti uye chigaro chepakati Pane gomba riri pakati pekupfuura waya yepakati, uye mhete yekuenzanisa inoiswa pamberi pemusoro wemuchina wekuenzanisa kudzvanywa. Iyo extrusion molding chikamu chinoumbwa nechigaro chefa sleeve uye chinofa sleeve. Nzvimbo yefa sleeve inogona kugadziriswa nebhoti kuburikidza nerutsigiro. , kugadzirisa nzvimbo yakaenzana yesleeve mold kusvika kune mold core, kuitira kuti ugadzirise kuenzana kwehupamhi hwechifukidzo che extruded, uye kunze kwemusoro kunogadzirwa nemudziyo wekupisa uye chigadziro chekuyera kupisa.
2.transmission system
Basa rekutapurirana system ndere kutyaira screw uye kupa torque uye kumhanya kunodiwa ne screw panguva ye extrusion process. Kazhinji inoumbwa nemota, inoderedza uye inotakura.
Pafungidziro yekuti chimiro chakafanana, mutengo wekugadzira weinodzikisira unoenderana nehukuru hwayo uye huremu. Nekuti chimiro uye huremu hweanodzikisira zvakakura, zvinoreva kuti zvimwe zvinhu zvinodyiwa panguva yekugadzira, uye mabhengi anoshandiswa akakurawo, izvo zvinowedzera mutengo wekugadzira.
Kune maextruder ane yakafanana screw dhayamita, yakakwirira-kumhanya uye yakakwirira-inoshanda extruders inoshandisa simba rakawanda kupfuura yakajairwa extruder, simba remota rinopetwa kaviri, uye saizi yefuremu yekudzikisa inowedzerwa zvakafanana. Asi high screw speed zvinoreva kuderera kwereshiyo. Kune iyo inodzikisira saizi imwe chete, iyo giya modulus yeiyo yakaderera yekudzikisa reshiyo yakakura kupfuura iyo yakakura yekudzikisa reshiyo, uye iyo inotakura mutoro wekudzikisa inowedzerwa zvakare. Naizvozvo, kuwedzera kwevhoriyamu uye huremu hweinodzikisira haina mutsara wakaenzana nekuwedzera kwesimba remota. Kana iyo extrusion vhoriyamu ichishandiswa sedhinominator uye yakakamurwa nehuremu hwekudzikisa, huwandu hwepamusoro-nokukurumidza uye hwakanyanya-hunobudirira extruders idiki, uye nhamba yeakajairika extruders yakakura.
Panyaya yekubuda kweyuniti, simba remota yeiyo yepamusoro-kumhanya uye yakakwirira-inoshanda extruder idiki uye huremu hweinodzikisira idiki, zvinoreva kuti iyo unit yekugadzira mutengo weiyo yepamusoro-kumhanya uye yakakwirira-inoshanda extruder yakaderera pane. iyo yevanhuwo zvavo extruders.
3.kupisa uye kutonhora mudziyo
Kupisa uye kutonhora mamiriro anodiwa kuti epurasitiki extrusion process ishande.
⑴Iyo extruder inowanzo shandisa kudziya kwemagetsi, iyo yakakamurwa kuita kupisa kupisa uye induction heat. Iyo yekudziya pepa inoiswa mune imwe neimwe chikamu che fuselage, muchina mutsipa uye musoro wemashini. Mudziyo wekudziya unopisa purasitiki muhumburumbira kunze kuti upise kusvika kune tembiricha inodiwa pakuita basa.
(2) Chishandiso chekutonhodza chinomisikidzwa kuti ive nechokwadi chekuti purasitiki iri mumhando yekushisa inodiwa nemaitiro. Kunyanya, ndeye kubvisa kupisa kwakanyanya kunogadzirwa neshear friction ye screw rotation, kuitira kudzivirira kuparara kwepurasitiki, kupisa kana kuomerwa mukuumbwa nekuda kwekushisa kwakanyanya. Kune marudzi maviri ekutonhodza dhiramu: kutonhora kwemvura uye kutonhora kwemhepo. Kazhinji, kutonhora kwemhepo kunonyanya kukodzera kune madiki uye epakati-kati-extruder, uye kutonhora kwemvura kana musanganiswa wemhando mbiri dzekutonhora kunowanzoshandiswa kune mahombe-extruders. Iyo screw kutonhora inonyanya kushandisa yepakati kutonhora kwemvura kuwedzera iyo yakasimba yekuburitsa chiyero chemidziyo. , kudzikamisa glue kubuda, uye kuvandudza chigadzirwa chemhando panguva imwe chete; asi kutonhora pahopper ndeyekusimbisa kufambisa mhedzisiro pazvinhu zvakasimba uye kudzivirira zvimedu zvepurasitiki kubva kunamira nekuda kwekukwira kwekushisa uye kuvhara chiteshi chekudya, uye chechipiri ndechekuona kushanda kwakajairwa kwechikamu chekutumira.
