Blow molding inzira inoshandiswa zvakanyanya kugadzira kugadzira maburi epurasitiki zvikamu. Inonyanya kufarirwa mukugadzirwa kwemidziyo, mabhodhoro uye zvimwe zvakasiyana-siyana zvigadzirwa. Pamwoyo wekuvhuvhuta muitiro ndiyokuvhuvhuta molding muchina, iyo inoita basa rinokosha mukuumba zvinhu zvepurasitiki muchigadzirwa chinodiwa. Muchinyorwa chino, isu tichatarisa pamatanho mana ekuputira kuvhuvhuta uye kuti muchina wekuvhuvhuta unofambisa sei nhanho imwe neimwe.
Usati wapinda muchikamu chimwe nechimwe, zvinodikanwa kuti unzwisise kuti blow molding chii.Kuvhuvhuta kuumbainzira yekugadzira inosanganisira kufuridza chubhu yepurasitiki inopisa (inonzi parison,) kuita mold kuita chinhu chisina mhango. Iyo nzira inoshanda uye inokwanisika, zvichiita kuti ive sarudzo yakakurumbira yekugadzira yakawanda yezvigadzirwa zvepurasitiki.
Matanho mana ekuumba kuvhuvhuta:
Blow molding inogona kukamurwa kuita matanho mana akasiyana: extrusion, kuumba, kutonhora uye ejection. Imwe neimwe nhanho yakakosha kukubudirira kwese kweiyo blow molding process, uye blower molding michina inofambisa imwe neimwe nhanho.
1. Extrusion
Nhanho yekutanga yekuvhuvhuta yekuvhuvhuta ndeye extrusion, uko epurasitiki pellets anodyiswa mumushini wekuvhuvhuta. Thekuvhuvhuta molding muchinainopisa mapepa epurasitiki kusvikira anyunguduka, achiita chubhu inopfuurira yepurasitiki yakanyungudutswa inonzi parison. Iyo extrusion process yakakosha nekuti inotarisa ukobvu uye kufanana kweparison, iyo inobata zvakananga kunaka kwechigadzirwa chekupedzisira.
Panguva ino, muchina wekuvhuvhuta unoshandisa screw kana plunger kusundira purasitiki yakanyungudutswa muforoma kuti igadzire parison. Tembiricha uye kudzvanywa kunofanirwa kunyatsodzorwa kuti ive nechokwadi chekuti plastiki yanyungudika zvachose uye inogona kuumbwa zviri nyore mumatanho anotevera.
2. Kuumba
Kana parison yaumbwa, nhanho yekuumba inopindirwa. Muchikamu chino, jeri rinosungirirwa muforoma kuti rigadzire chigadzirwa chekupedzisira. Muchina wekuvhuvhuta wobva wapinza mweya muprison, uchiita kuti uwedzere kusvika wazadza mold. Iyi nzira inozivikanwa se blow moulding.
Dhizaini ye mold yakakosha sezvo inosarudza saizi yekupedzisira uye kupera kwepamusoro kwechigadzirwa. Panguva ino, muchina wekuvhuvhuta unofanirwa kunyatso kudzora kudzvanywa kwemhepo uye tembiricha kuti ive nechokwadi chekuti parison inokura zvakafanana uye inonamatira kumadziro efodya.
LQ AS Jekiseni-kutambanudza-kuvhuvhuta kuumba muchina wekutengesa
1. Iyo AS yakatevedzana modhi inoshandisa matatu-chiteshi chimiro uye yakakodzera kugadzira midziyo yepurasitiki yakadai sePET, PETG, etc. Inonyanya kushandiswa mukutakura midziyo yezvizoro, mishonga, nezvimwe.
2. Injection-stretch-blow molding technology ine michina, molds, molding process, etc. Liuzhou Jingye Machinery Co., Ltd. yave ichitsvakurudza nekugadzira teknolojia iyi kwemakore anopfuura gumi.
3. Yedu Injection-Stretch-Blow Molding Machine ndeye-tatu-chiteshi: jekiseni preform, strent & blow, uye ejection.
4. Iyi nhanho imwe chete maitiro anogona kukuchengetedza simba rakawanda nekuti haufanirwe kudzoreredza preforms.
5. Uye inogona kuita kuti iwe uve nani kutaridzika kwebhodhoro, nekudzivisa preforms kukwenya kune mumwe nemumwe.
3. Kutonhodza
Mushure mokunge parini yave yakafuridzirwa uye yakaumbwa, inopinda muchikamu chekutonhora. Iyi nhanho yakakosha pakurapa purasitiki uye kuve nechokwadi chekuti chigadzirwa chekupedzisira chinochengeta chimiro chayo.Vhura michina yekuumbakazhinji shandisa nzira dzekutonhora kana mhepo kuderedza kupisa kwechikamu chakaumbwa.
Nguva yekutonhora inosiyana zvichienderana nerudzi rwepurasitiki inoshandiswa uye ukobvu hwechigadzirwa. Kutonhora kwakaringana kwakakosha nekuti kunokanganisa mashandiro emakanika uye huwandu hwese hwechigadzirwa chekupedzisira. Kana iyo yekutonhodza ikasadzorwa zvakanaka, inogona kukonzera warpage kana kumwe kukanganisa muchigadzirwa chakapedzwa.
4. Ejection
Nhanho yekupedzisira yekuputira kuumba ndeye ejection. Kana chigadzirwa chacho chatonhora uye chakasimba, iyokuvhuvhuta molding muchinainovhura mold kuti isunungure chigadzirwa chakapedzwa. Danho iri rinofanira kuitwa nemazvo kudzivirira kukuvadza chigadzirwa. Muchina uyu unogona kushandisa robhoti ruoko kana pini ejector kubatsira mukubvisa chikamu kubva mukuumbwa.
Mushure me ejection, chigadzirwa chinogona kufanira kupfuura mamwe matanho ekugadzirisa, akadai sekucheka kana kuongorora, isati yaiswa mukati uye kutumirwa. Kushanda kweiyo ejection nhanho kunogona kuve nekukanganisa kwakakosha pane yakazara kugadzirwa kutenderera uye saka chikamu chakakosha cheiyo blow molding process.
Blow molding inzira inoshanda uye yakasiyana-siyana yekugadzira inotsamira pane chaiyo mashandiro emuchina wekuvhuvhuta. Nekunzwisisa nhanho ina dzekuputira kuumba (extrusion, kuumba, kutonhora uye ejection), zvinokwanisika kuwana nzwisiso mukugadzirwa kweasina mapurasitiki zvigadzirwa. Danho rega rega rinoita basa rakakosha mukuona kunaka nekuenderana kwechigadzirwa chekupedzisira.
Sezvo kudiwa kwezvigadzirwa zvepurasitiki zvemhando yepamusoro kuri kuramba kuchikura kune akasiyana maindasitiri, kufambira mberi mukatiblow moldingtekinoroji nemakina zvinogona kuwedzera kushanda uye kugona kweiyo blow molding process. Kunyangwe iwe uri mugadziri, mainjiniya, kana kungofarira nyika yekugadzira mapurasitiki, kunzwisisa nhanho idzi kunodzamisa kunzwisisa kwako kwekuoma uye hunyanzvi kuseri kwekuridza machira ekuumba.
