N'ihe gbasara mbipụta nkwakọ ngwaahịa, igwe na-ebi akwụkwọ flexographic nke 4/6/8 bụ akụrụngwa bụ isi maka iji nweta mbipụta ọtụtụ agba mara mma. The "Central drum design" (nke a makwaara dị ka Central Impression, ma ọ bụ CI, Ọdịdị), site na ngbanwe ya ziri ezi maka mkpa mbipụta akwụkwọ nke ọtụtụ agba nke igwe ndị dị otú ahụ flexographic, abụrụla ihe ngwọta nkà na ụzụ bụ isi.
Dị ka ihe nhazi nke emepụtara maka mbipụta flexographic nke agba 4/6/8, igwe eji ebi akwụkwọ nke Ci Type Flexo dabara na isi ihe achọrọ nke mbipụta agba agba. Ọ na-egosiputa uru pụrụ iche na-enweghị atụ na akụkụ atọ dị mkpa: njikwa ziri ezi nke ihe mkpuchi ọtụtụ agba, nrụpụta arụmọrụ na mmepụta na-aga n'ihu, yana ndakọrịta na ihe dị iche iche - na-enye nkwado isi maka ịdị elu, mmepụta kwụsiri ike na mbipụta multi-agba flexographic.
I. Ndokwa doro anya: Ihe ngosi ngwa ngwa nke Central Drum Structure
Nhazi nhazi nke akụrụngwa obibi bụ n'ezie nzaghachi ziri ezi maka mkpa mmepụta kpọmkwem. Maka mbipụta flexo agba 4/6/8, ebe mmekọrịta ọtụtụ agba na nkenke dị elu bụ isi ihe achọrọ, mgbagha imewe nke ihe owuwu nke etiti na-enweta nha anya ezubere iche.
Site n'echiche nke isi ihe owuwu, Ci Type Flexo Printing Machine na-adabere na otu nnukwu dayameta, nnukwu ihe siri ike nke etiti mmetụta cylinder, nke a na-ahazi ọdụ ụgbọ mmiri 4 ruo 8 n'usoro okirikiri. N'oge a na-ebi akwụkwọ, ụlọ ọrụ niile na-acha agba na-emecha usoro mmetụta na drum etiti a dị ka ntụaka jikọtara ọnụ. Nke a "centralized akwụkwọ ntụaka" imewe fundamentally solves isi nsogbu nke "gbasasịrị ntụaka na-eduga mfe deviations" na multi-agba obibi akwụkwọ, na-eje ozi dị ka isi support maka ịghọta multi-agba synchronous ebipụta na multi-agba flexographic igwe.

II. Akụkụ isi anọ: Otu Central Drum si kwekọọ na mkpa mbipụta nke ọtụtụ agba
1. Deba aha ziri ezi: "Nkwenye nkwụsi ike" maka mmekọrịta ọtụtụ agba.
Mbipụta agba 4/6/8 chọrọ mkpuchi nke ọma nke ọtụtụ agba, yana Igwe nbipụta Central Flexo na-eme ka nke a bụrụ nkenke sitere na isi mmalite site na drum etiti ya:
● Mkpụrụ ahụ na-ejikọta ya na drum etiti a kapịrị ọnụ n'oge usoro ahụ niile, na-ebelata ngbanwe nke esemokwu na nbipụta agba agba ma na-ezere nchịkọta nke nkwụsịtụ;
● Ụlọ ọrụ niile na-acha agba na-eji otu drum etiti dị ka ntụaka nhazi, na-enye ohere ịhazigharị nrụgide kọntaktị na ọnọdụ n'etiti efere obibi akwụkwọ na mkpụrụ. Ndebanye aha ziri ezi nwere ike iru ± 0.1mm, na-emezu ihe dị mma machie chọrọ nke ụkpụrụ ọtụtụ agba;
● Maka ihe ndị nwere ike ịgbatị dị ka ihe nkiri na mpempe akwụkwọ dị mkpa, nkwado siri ike nke etiti etiti na-ebelata nrụrụ mkpụrụ, na-eme ka ọ bụrụ ihe na-agbanwe agbanwe na ndekọ ọtụtụ agba.
2. Ngwa ndakọrịta: Na-ekpuchi mkpa mbipụta dị iche iche
4/6/8 agba flexographic obibi akwụkwọ na-achọkarị ijikwa ihe dị iche iche, gụnyere ihe nkiri plastik (10-150μm), akwụkwọ (20-400 gsm), na foil aluminum. Ọdịdị nke etiti drum na-akwalite ndakọrịta n'ụzọ ndị a:
●Akụkụ etiti nke igwe eji ebi akwụkwọ na-enwekarị dayameta nke ≥600-1200mm, na-enye ebe mkpuchi mkpụrụ osisi buru ibu na nrụgide mmetụta otu. Nke a na-enyere aka ngbanwe na mbipụta mkpụrụ osisi siri ike ma na-ezere nsogbu indentation mpaghara;
●Ọ na-ebelata frictional kọntaktị n'etiti mkpụrụ na multiple ndu rollers, ẹsụhọde ihe ize ndụ nke scratches na wrinkles na mkpa substrates (eg, Pee fim) na adapting ka multi-agba obibi mkpa dị iche iche ihe.
3. Mmepụta arụmọrụ: The "Speed-Boosting Key" maka Multi-Color Printing
Ịrụ ọrụ nke mbipụta agba 4/6/8 na-adabere na "mmekọrịta" na "ịgbanwe mgbanwe mgbanwe" - akụkụ abụọ emebere site na nhazi drum etiti:
● Usoro okirikiri nke ọdụ agba agba na-enye ohere ka mkpụrụ ahụ mezue mbipụta ọtụtụ agba n'otu ngafe, na-ewepụ mkpa maka ịnyefe usoro n'etiti ọdụ ụgbọ mmiri. Ọsọ mmepụta nwere ike iru ruo 300m / min, na-eme mgbanwe maka mmepụta nke ọma nke iwu nnukwu agba ọtụtụ agba;
● N'oge mgbanwe agba, enwere ike ịhazigharị ọdụ agba ọ bụla n'adabereghị n'okirikiri etiti, na-enweghị mkpa ịhazigharị oghere n'etiti ọtụtụ rollers. Nke a na-ebelata oge mgbanwe n'usoro site na 40%, na-eme ka ọ dịkwuo mma maka mkpa nbipụta ọtụtụ agba dị mkpụmkpụ na-agba ọsọ.
4. Ọrụ ogologo oge: "Ngwọta kachasị mma" maka ọnụ ahịa na mmezi
Site n'echiche ogologo oge, imewe drum etiti na-ebuli ọnụ ahịa-arụmọrụ maka igwe nbipụta flexo etiti:
● Mmetụta ndekọ aha ziri ezi na-ebelata ọnụ ahịa mkpofu ibipụta nke ọma. Maka mita 10,000 ọ bụla nke mbipụta agba agba agbachachara, ọ na-ebelata mmefu ọnụ ahịa nke ihe mkpofu mkpụrụ na-akpata, na-achịkwa mfu akụrụngwa na isi mmalite ya;
● Nlekọta na-elekwasị anya na isi ihe dị na etiti etiti, na-achọ naanị nyocha nke bearings na nhazi ntụaka. Tụnyere akụrụngwa nwere ọtụtụ rollers nọọrọ onwe ya, ọnụ ahịa mmezi kwa afọ na-ebelata site na 25%.

III. Mmegharị ụlọ ọrụ: Ndozi n'etiti Central Drum na Trends na Multi-Color Flexographic Printing
Dị ka ụlọ ọrụ nkwakọ ngwaahịa na-akwalite ihe ọ chọrọ maka "ịdị mma gburugburu ebe obibi, nkọwa dị elu, na arụmọrụ dị elu," igwe eji ebi akwụkwọ flexo 4/6/8 kwesịrị imeghari ka ọ bụrụ ihe ọhụrụ dị ka inks dabeere na mmiri na UV. Njirimara mmetụta kwụsiri ike nke drum etiti ka mma dabara na ọsọ ihicha na mmetụta mbipụta nke ink ọhụrụ ndị a.
Ka ọ dị ugbu a, omume nke "obere-batch, multi-pattern" na nkwakọ ngwaahịa kemịkalụ kwa ụbọchị emeela ka ngwa ngwa n'usoro gbanwere uru nke ịgbà etiti ọbụna karịa ọnụ ahịa.
