Babban fasali naNanhai YaPlastic Extruder Machine shine "ci gaba da isar da saƙo, ingantaccen aikin filastik, da tsayayyen gyare-gyare."
The extruder ya ƙunshi tsarin guda biyar daga ciyarwa zuwa gyare-gyare, kowanne yana da fayyace ma'anar aiki kuma yana aiki tare:
1. Tsarin Ciyarwa
Mahimman abubuwan da aka gyara: hopper, feeder (kasuwa zuwa ciyarwar nauyi da ciyarwar tilastawa).
Aiki: A tsaye yana isar da ingantattun granules/foda na filastik zuwa sashin abinci na dunƙule, guje wa “gadowa” ( toshewar abubuwa a cikin hopper). Feeders na tilastawa (kamar masu ba da tagwaye) sun dace da babban danko ko kayan haɓaka cikin sauƙi, tare da daidaiton ciyarwa na ± 1%.
2. Tsarin Filastik
Abubuwan da ake buƙata: dunƙule, ganga, dumama da na'urorin sanyaya.
Aiki: Babban yanki don "rikitaccen ruwa mai ƙarfi" na robobi. Juyin juyayi yana haifar da karfi mai ƙarfi, wanda, tare da dumama dumama ganga (yawanci kashi 3-5), sannu a hankali yana narkewa kuma ya narke filastik mai ƙarfi; na'urar sanyaya (kamar sanyaya ruwa ko sanyaya iska) tana sarrafa zafin ganga don hana zafi da lalata kayan.
Mahimman sigogi: Matsakaicin tsayi-zuwa diamita (L/D) yawanci shine 20:1-30:1. The ganga dumama zafin jiki da aka gyara bisa ga roba abu (misali, PE 180-220 ℃, PVC 160-190 ℃).
3. Tsarin watsawa
Abubuwan da ake buƙata: Motoci, akwatin gear, hada guda biyu.
Aiki: Yana ba da ƙarfin ƙarfi ga dunƙule kuma yana sarrafa saurin dunƙule (yawanci 10-100 r/min). Motar sau da yawa tana amfani da injin mitar mitar mai canzawa ko injin servo, yana ba da damar daidaita saurin gudu; gearbox yana rage saurin mota kuma yana ƙaruwa da ƙarfi don saduwa da buƙatun aiki mai ɗaukar nauyi na dunƙule.
4. Die Head and Mold System
Mahimman abubuwan da aka haɗa: Die head (haɗa ganga da mold), mold (yana ƙayyade siffar ɓangaren samfurin).
Aiki: Gabatar da narkakkar robobi a cikin kogon mold kuma ya fitar da shi cikin takamaiman siffofi (misali, bututu, zanen gado, bayanan martaba). Ana buƙatar ƙera injin daidai gwargwado gwargwadon girman samfurin. Nau'o'in da aka saba sun haɗa da gyare-gyaren bututu, ƙwanƙwasa-baki (zane-zane/fina-finai), da gyare-gyare marasa tsari (bayanin kofa da taga).
5. Tsarin Siffata, sanyaya, da Tsarin Jawo
Abubuwan Mahimmanci: Siffar hannun riga (misali, vacuum size sleeve, calendering roller), tanki mai sanyaya (mai sanyaya ruwa/mai sanyaya iska), injin jan hankali.
Aiki: Da sauri yana sanyaya kuma yana siffata bayanin martabar zafin jiki da aka fitar, yayin da lokaci guda yana jan shi a daidaitaccen gudu ta hanyar injin ja don tabbatar da daidaiton girman samfurin (misali, karkacewar bangon bututu ≤ ± 0.1mm). Matsakaicin gudu dole ne ya dace da saurin extrusion don hana miƙewa ko wrinkling.
Dangane da bukatun samarwa, zamu iya samarwaguda-dunƙule extruders, twin-screw extruders, da kuma extrusion samar da Lines.
