1. Yakavharwa kurongedza
Rudzi urwu rwekurongedza rwakafanana ne shrink firimu kurongedza.Iyo firimu inoputira tireyi ichitenderedza tireyi, uye ipapo maviri anopisa anobatisa kupisa anovhara iyo firimu kumigumo yese.Iyi ndiyo yekutanga kushandisa fomu rekutamba firimu, uye mamwe mafomu ekurongedza akagadzirwa kubva pane izvi
2. Yakazara yakafara kurongedza
Rudzi urwu rwekuputira runoda kuti firimu rive rakakura zvakakwana kuti rivhare pallet, uye chimiro chepallet chinogara chiripo, saka chine chayo, chakakodzera firimu ukobvu hwe17～35μm.
3. Manual kurongedza
Iri rudzi rwekurongedza ndiyo yakapusa mhando yekutambanudza firimu kurongedza.Iyo firimu inosungirirwa pane rack kana ruoko-yakabatwa, inotenderedzwa netireyi kana firimu inotenderera patireyi.Iyo inonyanya kushandiswa kurongedza zvakare mushure mekuputirwa pallet yakuvadzwa, uye yakajairwa pallet kurongedza.Rudzi urwu rwekurongedza kumhanya kunononoka, uye yakakodzera firimu ukobvu ndeye 15-20μm;
4. Tambanudza firimu kuputira muchina kurongedza
Iyi ndiyo yakajairika uye yakawandisa fomu yekurongedza mechanical.Iyo tireyi inotenderera kana firimu rinotenderera rakatenderedza tireyi.Iyo firimu inogadziriswa pabhuraketi uye inogona kufamba ichikwira nekudzika.Iri rudzi rwekurongedza huwandu hwakakura kwazvo, dzinenge 15-18 matireyi paawa.Iyo yakakodzera firimu ukobvu ndeye 15-25μm;
5. Horizontal mechanical packaging
Yakasiyana kubva kune mamwe mapeji, iyo firimu inotenderedzwa nechinyorwa, icho chakakodzera kureba zvinhu kurongedza, senge makapeti, mapuranga, fiberboards, yakakosha-yakaumbwa zvinhu, nezvimwewo;
6. Packaging yepepa tubes
Iyi ndeimwe yeazvino kushandiswa kweakatambanudzwa firimu, iri nani pane yekare-yechinyakare bepa tube packaging.Iyo yakakodzera firimu ukobvu i30～120μm;
7. Kurongedza zvinhu zviduku
Iyi ndiyo yazvino kurongedza fomu yeyakatambanudzwa firimu, iyo isingagone chete kuderedza kushandiswa kwezvinhu, asi zvakare kuderedza nzvimbo yekuchengetedza yema pallets.Munyika dzekunze, rudzi urwu rwekuputira rwakatanga kuiswa muna 1984. Gore rimwe chete gare gare, zvakawanda zvekuputira zvakadaro zvakaonekwa pamusika.Iyi fomu yekurongedza ine mukana mukuru.Inokodzera firimu ukobvu hwe15～30μm;
8. Packaging yemachubhu netambo
Uyu muenzaniso wekushandiswa kwefirimu yakatambanudzwa mundima yakakosha.Midziyo yekurongedza inoiswa pakupera kwemutsara wekugadzira.Iyo yakazara otomatiki yakatambanudzwa firimu haingogone kutsiva tepi kuti isunge zvinhu, asi zvakare kutamba basa rekudzivirira.Ukobvu hunoshanda ndeye 15-30μm.
9. Tambanudza fomu ye pallet mechanism
Iko kurongedza kwefirimu yakatambanudzwa kunofanirwa kutambanudzwa, uye mafomu ekutambanudza epallet mechanical packaging anosanganisira kutambanudza kwakananga uye pre-kutambanudza.Kune mhando mbiri dzepre-stretching, imwe iri roll pre-stretching uye imwe ndeyemagetsi kutambanudza.
Kutambanudza kwakananga ndiko kupedzisa kutambanudza pakati petireyi nefirimu.Iyi nzira ine yakaderera kutambanudza reshiyo (inenge 15% -20%).Kana chiyero chekutambanudza chinodarika 55%～60%, iyo inodarika yekutanga goho remufirimu, hupamhi hwefirimu hunoderedzwa, uye puncture performance inorasika zvakare.Nyore kutyora.Uye pa60% kutambanudza chiyero, simba rekudhonza richiri rakakura, uye kune zvinhu zvakareruka, zvinogona kukanganisa zvinhu.
Iyo pre-stretching inoitwa nema rollers maviri.Iwo maviri roller e-roller pre-stretching akabatanidzwa pamwe chete negear unit.Chiyero chekutambanudza chinogona kunge chakasiyana zvichienderana nechiyero chegiya.Simba rekudhonza rinogadzirwa neturntable.Sezvo kutambanudza kunogadzirwa muchidimbu chinhambwe, kukakavara pakati pe roller nefirimu Iyo yakakurawo, saka hupamhi hwefirimu hahuna kuderera, uye yekutanga puncture performance yefirimu inochengetwa zvakare.Hapana kutambanudza kunoitika panguva yemhepo chaiyo, iyo inoderedza kuputsika kunokonzerwa nemicheto yakapinza kana makona.Iyi pre-stretching inogona kuwedzera kutambanudza chiyero kusvika 110%.
Iyo yekutambanudza nzira yemagetsi pre-stretching yakafanana neye roll pre-stretching.Misiyano ndeyokuti mipumburu miviri inotungamirirwa nemagetsi, uye kutambanudza kwakasununguka zvachose pakutenderera kwetireyi.Naizvozvo, inonyanya kuchinjika, inokodzera zvinhu zvakareruka, zvinorema, uye zvisina kujairika.Nekuda kwekunetseka kwakaderera panguva yekurongedza, iyo pre-kutambanudza chiyero cheiyo nzira yakakwira se300%, iyo inochengetedza zvakanyanya zvinhu uye inoderedza mutengo.Inokodzera firimu ukobvu hwe15-24μm.
