Kukweva inki inoreva maitiro ekuisa laminating, apo glue inodonhedza pasi inki layer pane inodhinda yepasi substrate, zvichiita kuti ingi inamire kune yepamusoro rubber roller kana mesh roller. Mhedzisiro yacho haina kukwana mavara kana ruvara, zvichikonzera kuti chigadzirwa chiraswe. Uyezve, iyo inki yakasungirirwa kune yepamusoro glue roller inotamirwa kune inotevera patani, ichikonzera tsvina. Chikamu chisina ruvara chine inki mavara uye kuderera kwakanyanya mukujeka, izvo zvinokanganisa kunaka kwechigadzirwa.
1.Iyo ine hukama nehuwandu hweglue yakashandiswa uye iyo yekushanda concentration
Mukana wechimwe chikamu chinopisa chinonyungudutsa chinonamira chinodhonza inki chakakwira kupfuura icho chezvikamu zviviri zvinonamira,iyo isingapatsanurwi kubva kumhando huru yekunamira uye diluent.
Nekuda kwehushoma hweglue yakaiswa, huwandu hweinki inokwevera pasi iri muchimiro chetambo dzakatsetseka, semamaki anokonzerwa nemameteor. Aya madotsi akanaka anonyanya kuoneka munzvimbo isina chinhu yefirimu repurasitiki, uye muchikamu chemuenzaniso, kunyatsotarisisa kunodiwa kuti uzviwane. Iyo gluing yakawanda ye scraper type yakaoma laminating machine inotarirwa nehuwandu hwemitsara uye kudzika kweanilox roller. Kunyanya kudzvinyirira pane scraper panguva yekushanda chaiko kunoderedzawo huwandu hweglue yakaiswa. Kana huwandu hweglue inoshandiswa idiki, chiitiko chekukwevera inki chakanyanya, nepo kana huwandu hweglue hwakaiswa hwakakura, chiitiko chekukwevera inki chinoderedzwa.
Kuwanda kwebasa remumba kwakanyatsoenderana nechiitiko chekukweva inki.Kana kusungirirwa kwechikamu chimwe chete chekunamatira kusingasviki 35%, iyo yakasimba yeadhesive yakakura isingasviki 3g /㎡, kana kuti kusungirirwa kwezvikamu zviviri zvinogadzirisa zvinonamidzira zvishoma kudarika 20%, uye iyo yakasimba yechinhu chikuru chekunamatira isingasviki 3.2g /㎡, zviri nyore kuitika inki yekudhirowa chiitiko, icho chine hukamawo neiyo chaiyo yekushandisa maitiro. Kana iyo yekushanda yakagadziriswa yakaderera uye inki inokwevera ichiitika, zvakakosha kuti uwedzere kushandiswa kwekugadzirisa kuti ugadzirise, izvo zvinoreva kuwedzera huwandu hwemumiririri mukuru kana kuderedza huwandu hwe diluent inoshandiswa.Kazhinji, kushanda kwechikamu chechikamu chimwe chete kunodzorwa kunenge 40%, uye zviri nani kudzora kusungwa kwezvikamu zviviri zvakapoteredza 25-30%, kuitira kuti inki inokwevera chiitiko inogona kugadziriswa.
2. Inoenderana nekumanikidzwa kweglue roller
Mune yakaoma composite process, gluing pressure roller inowanzoshandiswa, iyo inoshandiswaita kuti gluing coating iwedzere yunifomu uye kuderedza chizvarwa chebubbles. Kana inki ichikwevera ichiitika, kunze kwekutarisa huwandu hweglue yakaiswa uye kusungirirwa kwekushanda, ndiko kumanikidza kwerubha roller.
Kazhinji, kana dzvinyiriro inopfuura 4MPa, pane mukana wekudhonza inki. Mhinduro ndeyokuderedza kudzvinyirira, uye panguva imwe chete, mushandi ane unyanzvi anofanira kushandisa jira kuti anamate diluent kupukuta nzvimbo yeinki yekumhanya anilox roller. Kana yakanyanya kuoma, iyo anilox roller inofanira kumira kuchenesa.
3. Yakabatana nehutano hweglue roller
Rubber roller irikwete kutsetseka kana kutetepa, uye inogona kukweva ingi, iyo inonyatso kuratidzwa pane chimwe chinhu chinopisa chinonamira chinonyunguduka.
Nekuda kwekusaenzana uye kushata kweresin, ingi yakadhonzwa haina kurongeka uye yakagovaniswa zvisina kuenzana, ichisiya mavara eingi munzvimbo isina chinhu, zvichikonzera kuderera kwekujeka, kurasikirwa kweiki muruvara, uye zvinyorwa zvisina kukwana. Kuti uchinje chiitiko ichi, zvinodikanwa kutsiva iyo yakatsetseka uye yakapfava gluing roller.
4. Inoenderana nekumhanya kwemuchina uye kupisa kwekuomesa
Kumhanya kwemuchina kunoratidza kuti chinongedzo chiri pakati peinki layer uye chinonamira pane iyo firimu layer inochinja munguva yekunyorova.
Kazhinji, nekuda kwekunonoka kwemuchina kumhanya, pane chiitiko chekukwevera inki, iyo inogadziriswa nekuwedzera kukurumidza uye kuderedza nguva yekugara pakati peinki layer uye inonamira interface. Mukufungidzira, kana kumhanya kwemuchina kwakawedzera, tembiricha yekuomesa inofanirawo kuwedzera. Panguva imwecheteyo, kana kumhanya kwemuchina kuchiwedzerwa panguva yekushanda chaiko, inofanirwa kucherechedzwa kana paine zvimwe zvikanganiso, sekutamisa zvinhu, uye kugadziridzwa kunoenderana kunofanirwa kuitwa.
5. Yakabatana nekunamatira kwekudhinda substrate kana inki
Kana marudzi akasiyana einki achishandiswa pakudhinda gravure, kuitika kwekukanganisa kunonyanya kuratidzwa panguva yekuchera.
Ingi inogona kupatsanurwa kuita inki yekudhinda uye inki yemukati yekudhinda. Pamusana pemhando dzakasiyana dzeinki, kusungirirwa kwavo kunogona kunge kwakasiyana kana kusapindirana, uye kunamatira kusina simba kunogona kutungamirira kune kusina simba. Kana yakaoma lamination inoshandiswa, zviri nyore kukonzera inki kudhonza. Kana kushushikana kwepamusoro kweiyo substrate yekudhindisa kwakashata, kunowanzoita kudhonza inki.
Iyo yakadhonzerwa pasi inki layer inoratidzika seyose, uye ingi inonamatira kune glue basin, zvichikonzera turbidity uye tsvina. Kana iyo yakatodhindwa, kuitira kuti udzivise kutambisa, kukurumidza kwemashini kunogona kuwedzerwa, huwandu hweglue hunogona kuwedzerwa, uye glue concentration inogona kuwedzerwa panguva imwe chete. Deredza kudzvanya parubber roller uku uchidzikisa kushushikana kwekusunungura.
6. Yakabatana nemagetsi zvinhu
Panguva yekushanda, kana mechanical kukundikana kuitika, zvichiitakusaenzana gluing kana kushambidzika kwakashata, zvinogonawo kukonzera kudhonza inki.
Iko kuwiriranisa kwepamusoro rubber roller uye anilox roller inopedzwa nemagiya maviri anoenderana. Kana paine inki yekukweva chiitiko, kunyatsotarisisa kunofanirwa kuitwa. Ichaonekwa kuti inki inokwevera inoitika nekuda kwekuzununguka kwepamusoro rubber roller uye kupora kwakashata. Chikonzero chekuzununguka kunokonzerwa nekupfeka kwakanyanya uye asynchronous gear mazino.
Kana uine chero Packaging zvinodiwa, unogona kutibata nesu. Semugadziri anochinjika wekurongedza kweanopfuura makore makumi maviri, isu tinokupa yako chaiyo yekurongedza mhinduro zvinoenderana nechigadzirwa chako chinodiwa uye bhajeti.
