Zvinhu zvakakosha zveNanhai YaPlastic Extruder Machine "inoramba ichiendesa, yakakwirira-inoshanda plasticizing, uye yakagadzikana kuumba."
Iyo extruder ine mashanu epakati masisitimu kubva pakudyisa kusvika pakuumbwa, imwe neimwe iine basa rakanyatsotsanangurwa uye kushanda pamwe chete:
1. Kudyisa System
Zvikamu zvepakati: hopper, feeder (yakakamurwa kuita giravhiti yekudya uye yekumanikidza kudya).
Basa: Inoendesa zvakasimba epurasitiki granules / hupfu kune iyo screw feed chikamu, kudzivirira "bhiriji" (kuvharika kwezvinhu muhopper). Kumanikidzirwa mafeeders (akadai sematwin-screw feeders) akakodzera kune yakakwira-viscosity kana zviri nyore agglomerated zvinhu, zvine chokwadi chekudya che ± 1%.
2. Plasticizing System
Core components: screw, barrel, kudziyisa uye kutonhora zvishandiso.
Basa: Nzvimbo yakakosha ye "solid-liquid conversion" yemapurasitiki. Iyo screw kutenderera inogadzira shear simba, iyo, yakasanganiswa neyakakamurwa kupisa kwembiya (kazhinji 3-5 segment), zvishoma nezvishoma inopfava uye inonyungudutsa iyo purasitiki yakasimba; mudziyo wekutonhodza (wakaita sekutonhodza kwemvura kana kutonhodza mhepo) unodzora tembiricha yedhiramu kudzivirira kupisa nekushatisa kwezvinhu.
Makiyi paramita: Iyo screw urefu-kusvika-dhayamita reshiyo (L/D) inowanzo 20:1-30:1. Iyo tembiricha yekudziya yedhiramu inogadziriswa zvinoenderana nepurasitiki zvinhu (semuenzaniso, PE 180-220 ℃, PVC 160-190 ℃).
3. Transmission System
Zvikamu zvepakati: mota, gearbox, coupling.
Basa: Inopa simba rakagadzikana kune screw uye inodzora screw speed (kazhinji 10-100 r/min). Iyo mota inowanzoshandisa inosiyana frequency mota kana servo mota, ichibvumira kurongeka kwakaringana kumhanya; bhokisi regiya rinoderedza kumhanya kwemota uye rinowedzera torque kuti isangane neyakakura-mutoro mashandiro ezvinodiwa zve screw.
4. Die Head uye Mold System
Core components: Die head (inobatanidza mbiya uye mold), mold (inosarudza muchinjika-chikamu chimiro chechigadzirwa).
Basa: Inopinza purasitiki yakanyungudutswa mugomba rekuumbwa uye inoiburitsa mune chaiyo maumbirwo (semuenzaniso, mapaipi, mapepa, profiles). Iyo mold inoda kunyatsogadzirwa zvinoenderana nehukuru hwechigadzirwa. Mhando dzakajairika dzinosanganisira zviumbwa zvepombi, flat-mouth molds (mashiti/mafirimu), uye zviumbwa-zvisina kurongeka (masuo nemahwindo profiles).
5. Kuumba, Kutonhora, uye Kudhonza System
Zvikamu Zvikuru: Sleeve yekugadzira (semuenzaniso, vacuum sizing sleeve, calendering roller), tangi yekutonhora (mvura-yakatonhorera / mhepo-yakatonhorera), muchina wekudhonza.
Basa: Inokurumidza kutonhora uye inoumba iyo extruded yepamusoro-tembiricha mbiri, panguva imwe chete ichiidhonza nekumhanya yunifomu kuburikidza nemushini wekudhonza kuti uve nechokwadi chekugadzikana kwechigadzirwa (semuenzaniso, pombi madziro ukobvu kutsauka ≤ ± 0.1mm). Iyo yekumhanyisa kumhanya inofanirwa kuenderana nekumhanya kwekuwedzera kudzivirira chigadzirwa kutambanudza kana kuunyana.
Zvichienderana nezvinodiwa zvekugadzira, tinogona kupasingle-screw extruders, mapatya-screw extruders, uye mitsetse yekugadzira extrusion.
