Single Screw Barrel Yekuvhuvhuta Firimu: Tsanangudzo uye Basa
Chii chinonzi Single Screw Barrel yeKuvhuvhuta Firimu
Imwe screw barrel yekufuridza firimu chikamu chakakosha cheiyo yakafuridzwa firimu extrusion process. Iyo ine sikou inotenderera mukati memugaba wakasimba, wecylindrical. Iyi setup inobata mbishi epurasitiki zvinhu uye inoigadzirira kuti iite firimu. Iyo screw inotenderera uye inofambisa zvinhu kumberi, nepo mbiya inoshandisa kupisa nekumanikidza. Pamwe chete, vanoshandura mapuranga epurasitiki akasimba kuita mushe wakatsetseka, wakanyunguduka wakagadzirira extrusion.
Iyo single screw barrel yekufuridza firimu inoita zvinopfuura kungofambisa zvinhu. Inonyunguduka, inosanganisa, uye inovaka kudzvanywa kunodiwa kusundira plastiki kuburikidza nekufa. Iyi nzira inogadzira yunifomu yakanyunguduka, iyo yakakosha pakugadzira firimu remhando yepamusoro.
Basa muBlown Film Extrusion Process
Iyo imwechete screw barrel yekufuridza firimu inotamba akati wandei akakosha mabasa muextrusion process:
- Inotakura zvinhu zvakasvibirira kubva muhopi kuenda mudhiramu.
- Iyo inonyunguduka uye inoputira iyo polymer, kuve nechokwadi kuti kunyunguduka kwakaenzana uye kunoenderana.
- Inosanganisa zvinhu kuti ive nechokwadi chekuti ruvara uye zvinowedzera zvinopararira zvakaenzana.
- Inovaka kumanikidza uye inosundira plastiki yakanyunguduka yakananga kumusoro wekufa.
Iyo screw dhizaini mukati medhiramu inokanganisa mashandiro anoita matanho aya. Zvimiro zvakaita semusanganiswa uye zvivhariso zvikamu zvinobatsira kuvandudza kunyungudika uye kusanganiswa kwemavara. Iyo yakanyatsogadzirwa screw inogona kuenzanisa kupisa uye kumanikidza, izvo zvinotungamira kune zviri nani firimu zvinhu uye yakakwirira kubuda. Thekusimba kwedhiramu uye chaiyo engineeringzvakare batsira kuchengetedza hurongwa uhwu huchimhanya zvakanaka, kuderedza nguva, uye kuchengetedza simba.
Kushanda Nheyo yeSingle Screw Barrel Yekuvhuvhuta Firimu
Kudyisa uye Kuendesa Zvinhu
Rwendo rwepurasitiki mune yakafuridzwa firimu extrusion inotanga pahopper. Pano, mapeti epurasitiki mbishi anodonhera mudhiramu. Thesingle screw barrel yekufuridza firimuinoshandisa sikuruu inotenderedza kubata aya mapellets uye oaendesa kumberi. The screw's design inokosha zvikuru. Kudzika nendege muchikamu chescrew's feed kunobatsira kutakura zvimwe zvinhu pasina kuputsa nekukurumidza. Sezvo screw inotendeuka, inosundidzira mapellets pamwe nedhiramu, kuita shuwa kuti anofamba zvakanaka uye zvakatsiga.
Zano: Kudzika uye kudzika kwechaneli kwescrew kunokanganisa kuti ingani zvinhu zvinoenda kumberi uye kuti inofamba zvinyoro sei. Chinamo chikuru chinofambisa zvimwe zvinhu, ukuwo kanzwi kadiki kachidzvanya nekugadzirira purasitiki kuti rinyunguduke.
Heano kutarisa nekukurumidza pamatanho anosanganisirwa muchikamu ichi:
- Plastic pellets kupinda hopper.
- Iyo screw inotenderera uye inodhonza ma pellets mudhiramu.
- Siruuru yakadzika ndege nekunamira kunofambisa ma pellets kumberi.
Kunyunguduka uye Plasticization
Kamwe mapellets akawedzera kupinda mudhiramu, anotanga kupisa. Mahita emudhiramu uye kukweshana kunobva mukutenderedza siruu zvinonyungudutsa purasitiki. Thesingle screw barrel yekufuridza firimuinofanira kunyungudutsa plastiki zvakaenzana kudzivirira mapundu kana mavara asina kunyunguduka. Thegeometry ye screw, kufanana kwayokureba-kusvika-dhayamita (L/D) reshiyouyecompression ratio, inoita basa guru pano. Iyo yakareba screw inopa plastiki nguva yakawanda yekunyunguduka uye kusanganisa, izvo zvinotungamira kune yakapfava, yakawanda yunifomu kunyunguduka.
- The screw's speed zvakare inokosha. Inokurumidza kumhanya inogadzira shear yakawanda, iyo inobatsira kunyungudutsa plastiki, asi yakawandisa inogona kupisa nekuikuvadza.
- Special features like barrel grooves orkusanganisa piniinogona kuwedzera kusanganisa uye kubatsira kunyungudika kuve kwakanyanya.
Iyo screw yakanyatsogadzirwa uye dhiramu inochengetedza tembiricha yakaringana, saka purasitiki inonyunguduka zvakanaka uye inogara yakafanana. Iyi nhanho yakakosha pakugadzira firimu remhando yepamusoro.
Kudzvinyirira, Kuveura, uye Kudzvinyirira
Sezvo purasitiki yakanyungudutswa ichienda kumberi, gwara re screw rinodzikira. Shanduko iyi inomanikidza plastiki, inosvina chero mweya, uye inovaka kumanikidza. Iyo screw zvakare inogadzira mauto ekugera, ayo anosanganisa kunyunguduka uye kutyora chero clumps kana gels. Kusanganisa zvinhu zvakadaiMaddock kana pineapple mixersanogona kubatsira pano. Vanoparadzanisa uye vanobatanidza zvakare kunyunguduka, kuve nechokwadi kuti zvese zvinosanganiswa zvakanaka pasina kupisa plastiki.
| Factor | Basa muMelt Quality | Mhedzisiro pamhando yeFirimu | Chenjero/Kutengeserana |
|---|---|---|---|
| Compression Ratio | Inomanikidza plastiki, inobatsira kunyunguduka uye kusanganisa | Inoita kuti yunifomu inyunguduke, inodzivirira kukanganisa | Kunyanya kukwira kunogona kukonzera kupisa |
| Kudzika Kwendege | Inodzora shear force | Inoputsa masumbu, inoparadzira zvinowedzera | Kugera kwakanyanya kunogona kupisa kunyungudika |
| Kuveura | Misanganiswa uye homogenizes inonyunguduka | Inovandudza kujeka uye simba | Inofanirwa kuenzana kudzivirira kukanganisa |
Maitiro akadzikama ekumanikidza uye kuveura anobatsira iyo imwe screw barrel yekufuridza firimu kuburitsa kunyungudika kuri zvese yunifomu uye yakagadzirira kuumbwa.
Extrusion kubudikidza Die
Mushure mokunge kunyunguduka kwasvika kumagumo ebhodhoro, inotarisana nekufa. Dhayi inoumba purasitiki yakanyungudutswa kuita chubhu yakatetepa. Dhizaini yezvose zviri zviviri die uye imwe screw barrel yekufuridza firimu inofanira kushanda pamwechete. Kana iyo yakanyunguduka isiri yunifomu kana kutonhora kwakadzimwa, firimu rinogona kubuda nehupamhi husina kuenzana kana kukanganisa.
- Thescrew uye barrel kudzora kunyunguduka uye tembiricha.
- Iyo inofa inoparadzira iyo yakanyunguduka zvakaenzana, ichiita bubble rinoputika nemhepo.
- Iyo bubble inotonhorera, inodonha, uye inoputika kuita inoenderera firimu sheet.
Ongorora: Kuenderana kunyungudika kuyerera uye tembiricha yakakosha pakugadzira firimu rine kunyange ukobvu uye nesimba rakanaka. Chero shanduko mukumhanyisa screw, tembiricha yebhari, kana kufa dhizaini inogona kukanganisa chigadzirwa chekupedzisira.
Iyo yese maitiro, kubva pakudyisa kusvika kune extrusion, inovimba nekuchenjerera kutonga uye smart dhizaini. Kana zvese zvashanda pamwe chete, mhedzisiro ifirimu remhando yepamusoro rakafuridzwa rakagadzirira kurongedza, zvekurima, kana zvimwe zvinoshandiswa.
Zvikamu zvakakosha uye Magadzirirwo Mafungidziro eiyo Imwe Screw Barrel Yekuvhuvhuta Firimu
Zvikamu Zvikuru: Screw, Barrel, Hopper, Die, Drive System
A single screw barrel yekufuridza firimuinovimba nezvikamu zvikuru zvakati wandei zvinoshanda pamwechete kushandura mapepa epurasitiki kuita firimu rakatsetseka. Chikamu chimwe nechimwe chine basa rakakosha:
- Hopper: Inodyisa mbishi epurasitiki pellets muhurongwa.
- Bharel: Inobata sikuruu uye inopisa zvinhu.
- Chikururu: Inotenderera kufamba, kunyunguduka, uye kumanikidza purasitiki.
- Zvidziya: Kutenderedza dhiramu kuchengetedza tembiricha chaiyo.
- Die: Inoumba purasitiki yakanyungudutswa kuita chubhu yakatetepa.
- Dhiraivha System: Inodzora kumhanya kwesiruu kuti ibude zvakadzikama.
| Chikamu | Function |
|---|---|
| Chikururu | Inofamba, inonyunguduka, uye inomanikidza iyo polymer; ine feed, compression, uye metering zones. |
| Bharel | Cylindrical housing yakakomberedza sikuruu; inopa inodzorwa kudziyisa. |
| Die Head | Inoumba iyo yakanyungudutswa polima isati yawedzera. |
| Mhepo Mhete | Inotonhodza iyo yakawedzera firimu bubble. |
| Nip Rollers | Gadzirisa bubble mupepa refirimu. |
Iyo drive system inoshandisa advanced controls kuchengetedza iyoscrew speed steady. Izvi zvinobatsira kuti maitiro arambe akagadzikana uye kuchengetedza firimu remhando yepamusoro.
Kupesvedzera kweScrew uye Barrel Dhizaini Paramita (L/D Ratio, Compression Ratio)
Dhizaini yescrew uye mbiya inokanganisa kuti muchina unonyungudika nekusanganisa plastiki. Hurefu-kusvika-dhayamita (L/D) reshiyo yakakosha. Chiyero chepamusoro cheL / D chinopa plastiki nguva yakawanda yekunyunguduka nekusanganisa, izvo zvinogona kuvandudzafilm quality. Nekudaro, kana reshiyo yakawandisa, inogona kushandisa simba rakawanda uye kukonzera kupfeka.
Iyo compression ratio zvakare ine basa. Ndiyo reshiyo yekudzika kwescrew's feed channel kudzika kwayo metering chiteshi. A yakanaka compression reshiyo inobatsira kunyungudutsa epurasitiki zvizere uye kudzivirira kukanganisa. Kana chiyero chakanyanya kuderera, plastiki inogona kusanyungudika zvakakwana. Kana yakanyanya kukwirira, screw inogona kupisa uye kugadzira zvimedu zvakasimba, izvo zvinogona kukuvadza firimu kunaka.
Zano: Kusarudza L/D chaiyo uye compression ratios zvinoenderana nerudzi rwepurasitiki uye mhando yezvinodiwa zvefirimu.
Maintenance, Troubleshooting, uye Optimization Tips
Nguva dzose kuchengetedzainochengeta siruvha imwe chete yekufuridza firimu richifamba zvakanaka. Vashandi vanofanira:
