Kodi Makina Opangira Blow Molding ndi Chiyani?

Kuumba ndi njira yopangirakupanga zinthu zopanda kanthuPogwiritsa ntchito mpweya wopanikizika kuti upukute ndi kutupa mazira otentha osungunuka omwe atsekedwa mu nkhungu. Kuumba kopanda kanthu kumatulutsa kuchokera ku extruder ndikuyika chopanda kanthu cha thermoplastic chomwe chikadali mu mkhalidwe wofewa mu nkhungu youmba. Kenako kudzera mu mpweya wopanikizika, pogwiritsa ntchito mpweya wopanikizika kuti usinthe chopanda kanthucho m'mphepete mwa die cavity, motero umatulutsa zinthu zopanda kanthu za khosi lalifupi.

Kuumba zinthu zopanda kanthu ndi ukadaulo wofunikira kwambiri popanga zinthu zopanda kanthu za pulasitiki.Pafupifupi ma thermoplastics onse angagwiritsidwe ntchito popanga zinthu zopanda kanthu monga polyethylene, PVC, polypropylene, polystyrene, linear polyester, polycarbonate, polyamide, cellulose acetate ndi poly acid formaldehyde resin, ndi zina zotero.

Ndi ukadaulo uwu woumba, sungathe kokhapanga kakang'ono voliyumumabotolo a ma milliliters angapo, komanso akhozapangamalita zikwi zambirivoliyumu yayikulumigolo ndi matanki osungira madzi, komanso mipira yoyandama, matanki amafuta a magalimoto ndi ma kayak.

Kodi zinthu zopangira utomoni ziyenera kukhala ndi makhalidwe otani?

1.Kukana kupsinjika kwa chilengedwe: monga chidebe, imatha kupewa ming'alu ikakhudzana ndi surfactant;

2.Kulimba kwa mpweya (kukana kulowa kwa mpweya): amatanthauza makhalidwe omwe amaletsa kufalikira kwa mpweya, carbon dioxide, nayitrogeni ndi nthunzi ya madzi kunja.

3.Kukana kugwedezeka: kuti ateteze katundu yemwe ali mu chidebecho, zinthuzo ziyenera kukhala ndi mphamvu yolimbana ndi kugwedezeka komwe sikungasweke kuchokera kutalika kwa mita imodzi.

4. Kuphatikiza apo, pali kukana mankhwala, kukana mosasunthika, kulimba komanso kukana kutulutsa.

Kodi ubwino wa kupanga zinthu zolimbitsa thupi ndi wotani?

1. Kapangidwe ka dzenje, kokhala ndi mipanda iwiri kangathe kuyamwa ndikuchotsa mphamvu yokhudza mphamvu;

2. Kapangidwe kosinthasintha, kogwira ntchito kwambiri komanso kotsika mtengo wopanga;

3. Ukadaulo wokonza zinthu ungasinthe makulidwe a mwana wosabadwayo;

4.Panthawi yokonza, makulidwe a chinthucho amatha kusinthidwa nthawi iliyonse popanda kusintha nkhungu;

5. Kuumba kotsika (kupsinjika kwamkati kwa nkhungu ndi kochepa kwambiri kuposa kwa jekeseni), kuti kukhale kolimba, kukana dzimbiri kwa mankhwala komanso magwiridwe antchito otentha kwambiri;

6. Kusiyanasiyana kwa msonkhano: screw yodzigwira yokha, die insert, rivet expansion fastener;

7. Nkhungu yosavuta, yotsika mtengo komanso yogwira ntchito yochepa;

8. Chifaniziro cha chitsanzo chokhala ndi mtengo wotsika chingapangidwe mwachangu.

Kuumba mabotolo ndi njira yopangira zinthu zomwe zimapangidwira pulasitiki yopanda kanthu: Imagwiritsidwanso ntchito popanga mabotolo agalasi. Kawirikawiri, pali mitundu itatu ikuluikulu ya kuumba mabotolo:Kuumba nkhonya yotulutsa mpweya, kupanga nkhonya yopangira jekeseni, ndi kupanga nkhonya yotambasula jekeseni.

Mawonekedwe:

.Kugwira ntchito kokhazikikandi PLC yapamwamba.

Kutumiza ma preforms okhandi conveyor.

Kulowa mwamphamvukomanso kugawa kutentha bwino komanso mwachangu mwa kulola mabotolo kuti azizungulira okha ndikusinthasintha mu njanji nthawi imodzi mu infrared preheater.

Kusintha kwakukulukuti chotenthetsera chizitha kutentha mawonekedwe ake mwa kusintha chubu cha kuwala ndi kutalika kwa bolodi lowunikira m'dera lotenthetsera, komanso kutentha kosatha mu chotenthetsera chimagwiritsa ntchito chipangizo chotenthetsera chokha.

Chitetezo chapamwambandi chipangizo chodzitsekera chokha chachitetezo pa ntchito iliyonse yamakina, zomwe zipangitsa kuti njirazo zikhale zotetezeka ngati njira ina yawonongeka.

Kwenikwenikuumba nkhonyandi chidebe chopangira pulasitiki yopanda kanthu chomwe chimalumikiza gawoli. Chimapezeka m'mitundu ndi makulidwe osiyanasiyana. Kuumba ndi kupangira jekeseni ndi njira imodzi yomwe imagwiritsidwa ntchito kwambiri ndipo imagwiritsidwa ntchito kwambiri ndi njira iyi.panga zida zapulasitiki zapamwamba kwambiri pamtengo wotsikakotero iyi ndi njira yabwino yotsika mtengo. Kuumba mozungulira ndi njira yakale yomwe imagwiritsidwa ntchito popanga zinthu zopanda kanthu. Mu kupanga mozungulira zinthu zambiri zimakhudzidwa monga "mtundu wa pulasitiki, liwiro, liwiro, kutentha.Mpweya ndi chimodzi mwa zinthu zofunika kwambiri ndipo umagwira ntchito yofunika kwambiri popanga chikombole cha blowing. Mpweya umalowetsedwa mu chikombole kuti ukule ndikupatsa mawonekedwe omwe mukufuna. Njira yopangira chikombole cha blowing ndi yosavuta kwambiri, imagwiritsidwa ntchito kwambiri ndipo imaphatikizapo makina otsika mtengo, kupanga mabotolo apulasitiki pogwiritsa ntchito njirayi ndikotsika mtengo kwambiri poyerekeza ndi kupanga jekeseni. Mu kupanga chikombole cha blowing sikofunikira popanga chikombole chapamwamba kwambiri.

Kuumba zinthu mopanda mphamvu - ndi njira yapadera kwambiri yopangira zinthu zomwe zimapangidwira pulasitiki yopanda kanthu ndipo zimatha kulumikizidwa pamodzi.

Amakina oumbira nkhonyaimagwiritsidwa ntchito kwambiri popanga zakumwa zamalonda. Makina opangira zinthu zophikidwa amapanga botolo la pulasitiki malinga ndi njira yophikira, mwachitsanzo kulongosola mphamvu ya botolo loti lipangidwe. Makinawa ali ndi nkhungu, chowongolera cha logic chomwe chingakonzedwe, ndi zida zamakanika ndi zamagetsi.
