Muchina mukuru wepurasitiki pelletizing muchina ndeye extruder, iyo ine extrusion system, transmission system uye yekudziya uye kutonhora system.Gadzira zvine simba zviwanikwa zvinogonekazve, uchishandura marara kuita pfuma.
1. extrusion system extrusion system inosanganisira hopper, musoro, plastiki kuburikidza ne extrusion system uye plasticized kuva yunifomu yakanyunguduka, uye mukugadzirisa kwakasimbiswa pasi pekumanikidzwa, ne screw inopfuurira extrusion musoro.
(1) screw: ndiyo inonyanya kukosha chikamu che extruder, inoenderana zvakananga nehukuru hwekushandisa uye kugadzirwa kweiyo extruder, yakagadzirwa nepamusoro-simba-inodzivirira corrosion-resistant alloy simbi.
(2) barrel: isimbi silinda, inowanzo gadzirwa nekupisa-kupisa, kusimba kwesimba, yakasimba kusapfeka, inodzivirira corrosion-resistant alloy simbi kana alloy simbi yakamisikidzwa necomposite simbi pombi.Iyo dhiramu inobatirana ne screw kuti ione kupwanya, kupfava, kunyunguduka, plasticizing, kupera simba uye compacting yepurasitiki, uye nekuenderera uye zvakaenzanirana kuendesa rabha kune inoumba system.Kazhinji kureba kwebhodhoro ndeye 15 ~ 30 nguva yedhayamita yaro, kuitira kuti ipurasitiki inodziya zvakakwana uye yakazara plastiki.
(3) Hopper: Pazasi pehopper ine mudziyo wekucheka-cheka kugadzirisa uye kucheka kuyerera kwezvinhu, uye divi rehopper rakashongedzerwa neburi rekuona uye yakagadziriswa yekuyeresa mudziyo.
(4) Musoro uye mold: Musoro unoumbwa nesimbi yemukati sleeve uye kabhoni simbi yekunze sleeve, uye musoro wakashongedzerwa nekuumba mold.Basa remusoro ndere kushandura plastiki inotenderera inonyunguduka kuita yakafanana mutsara inofamba, iyo yakaenzana uye yakatsetseka yakaunzwa mune mold sleeve, uye kupa epurasitiki inodiwa yekuumba kumanikidza.Plastiki inogadzirwa nepurasitiki uye yakamisikidzwa mudhiramu yemuchina uye inoyerera nemumutsipa wemusoro kuburikidza neimwe nzira yekuyerera kuburikidza ne perforated filter plate ichipinda mukugadzira mold yemusoro, uye iyo mold core uye mold sleeve zvinonyatsoenderana kuti aumbe. annular gap ine kuderera kwechikamu chemuchinjikwa, kuitira kuti purasitiki inyunguduke inogadzira inoenderera yakakora tubular cladding layer yakatenderedza mutsara wepakati.Kuti ive nechokwadi chekuti chiteshi chepurasitiki chinoyerera mumusoro chine musoro uye kubvisa kona yakafa yepurasitiki yakaunganidzwa, kazhinji panoiswa sleeve yekuchinjisa, uye kubvisa kudzvinyirirwa kwepurasitiki extrusion, kune zvakare kumanikidza kuenzana mhete. set.Musoro wacho wakashongedzerwawo nedhireji yekururamisa uye yekugadziridza mudziyo, iyo yakanakira kugadzirisa uye kugadzirisa iyo concentricity yeiyo die core uye die sleeve.
2. Dhiraivha system Iyo dhiraivha system inoshandiswa kutyaira screw uye kupa iyo torque uye kumhanya kunodiwa ne screw panguva ye extrusion process, kazhinji inoumbwa nemagetsi mota, reducer uye mabheya.
3. kudziyisa uye kutonhora mudziyo Kupisa uye kutonhora kunodiwa kuti epurasitiki extrusion process ikwanise kuenderera.
(1) 2013 extrusion muchina unowanzo shandiswa kupisa magetsi, wakakamurwa mukupisa kupisa uye kupisa induction, kupisa pepa rakaiswa mumuviri, mutsipa, musoro zvikamu.Mudziyo wekudziya unopisa purasitiki mudhiramu kubva kunze kuti udziye kusvika kune tembiricha inodiwa pakuita basa.
(2) Chishandiso chekutonhodza chakamisikidzwa kuti ive nechokwadi chekuti purasitiki iri mumhando yekushisa inodiwa pakuita.Kunyanya, ndeyekubvisa kupisa kwakanyanya kunogadzirwa neshear friction ye screw inotenderera kuitira kudzivirira purasitiki kubva pakuora, kupisa kana kuumba matambudziko nekuda kwekupisa kwakanyanya.Kutonhodza kwemubhobho kwakakamurwa kuva marudzi maviri emvura-yakatonhodzwa uye mhepo-yakatonhodzwa, kazhinji kadiki uye yepakati-saizi extrusion muchina uchishandisa mhepo-yakatonhodzwa ndiyo inonyanya kufanira, hombe yakanyanya kunyoroveswa nemvura kana kusanganiswa kwemhando mbiri dzekutonhodza;screw cooling inonyanya kushandiswa pakati pemvura-yakatonhorera, chinangwa ndechekuwedzera chiyero chekutakura zvinhu zvakasimba, kudzikamisa huwandu hwerabha, uku uchivandudza kunaka kwechigadzirwa;asi kutonhora pahopper, imwe ndeyekusimbisa basa rekutakura zvinhu zvakasimba, kudzivirira purasitiki yegorosi inonamira kuvhara nekuda kwekupisa Chechipiri ndechekuona basa rakajairwa rechikamu chekufambisa.
