Cov Lus Qhia Kom Paub! Cov txheej txheem kev khiav hauj lwm rau kev siv Anilox Rollers, yuav tsum- Kawm thiab Yuav Tsum-Saib!

Anilox rollers yog 'lub plawv' ntawm flexographic printing presses, thiab lawv cov mob ncaj qha txiav txim siab luam ntawv zoo thiab cov nqi tsim khoom. Txhawm rau ua tus txheej txheem rau cov neeg ua haujlwm cov txheej txheem, txuas ntxiv lub neej kev pab cuam ntawm anilox rollers, thiab xyuas kom meej luam ntawv zoo, kuv lub koom haum tau tsim cov kev cai rau kev siv thiab kev saib xyuas ntawm anilox rollers. Kuv tab tom qhia lawv ntawm no rau kev siv, vam tias yuav txhawb kev paub ntawm ntau lub tuam txhab luam ntawv txog kev siv thiab kev saib xyuas ntawm anilox rollers.

PART 01

Yuav tsum muaj thiab ceev faj rau kev siv Anilox Rollers

1. Kev tshuaj xyuas ua ntej siv

1.1 Roller Surface Inspection

Ua ntej siv, tshuaj xyuas cov menyuam nto qhov muag pom hauv qhov teeb pom kev zoo thiab nrog lub teeb nyem kom ntseeg tau tias nws tsis muaj roj, tus cwj mem qhuav, cov khoom txawv teb chaws, txhaws hlwb, thiab khawb. Raws li pom nyob rau hauv daim duab 1, cov roj paug tau pom nyob rau ntawm cov menyuam nto thaum lub sij hawm ua ntej - siv tshuaj ntsuam xyuas.

Nws yuav tsum raug sau tseg tias kev tshuaj xyuas cov hlwb ntawm ceramic anilox rollers feem ntau yuav tsum muaj lub iav tsom iav ntau dua 200x. Rau anilox rollers nrog ntau dua 1000 LPI, yog tias lub hlwb pom meej meej ntawm qhov muag liab qab, feem ntau xav tau ib lub iav loj dua 400x.

2. Kev tshuaj xyuas kabmob

Manually rotate the bearing to ensure it turns smoothly without any sticking or abnormal noise. Check the bearing clearance (axial clearance >0.1mm yuav tsum tau hloov tam sim). Nws raug nquahu kom siv cov bearings kaw kom tiv thaiv corrosion los ntawm number case thiab ntxuav cov neeg ua haujlwm.

3. Kev txheeb xyuas qhov ntsuas

Ua ntej mounting lub anilox cov menyuam, xyuas kom meej tias cov kab suav (LPI) thiab ntim (BCM) ntawm anilox roller phim cov kev txiav txim ntau lawm tam sim no los tiv thaiv kev siv cov menyuam tsis raug. Nws raug pom zoo tias tus naj npawb tiag tiag ntawm cov menyuam yaus anilox yuav tsum tau qhia meej meej ntawm qhov kev txiav txim ntau lawm, vim tias BCM ntim ntawm cov menyuam yuav muaj kev ua haujlwm ntev. Sau tus lej anilox cov menyuam tiag tiag txhua zaus ua qauv thiab nruj me ntsis siv tib tus lej lej thaum tso qhov kev txiav txim tiag. Yog tias cov menyuam raug puas tsuaj thiab yuav tsum tau hloov pauv, rov ntsuas dua thiab hloov kho yog qhov tsim nyog kom tsis txhob muaj xim tsis sib xws txawm tias siv cov yob nrog tib qhov tsis sib xws, uas yuav nkim sijhawm thiab cov khoom siv.

II. Installation thiab Commissioning

1. Txuj kev teeb tsa

Siv cov cuab yeej tshwj xeeb (xws li lub tes tsho hydraulic) rau kev teeb tsa. Tsis txhob ntaus lossis rauj cov menyuam kom tsis txhob ua rau cov tub ntxhais kawm lossis cov kabmob. Xyuas kom meej tias qhov chaw sib cuag ntawm lub cev ntawm cov menyuam thiab cov phaj phab ntsa yog huv si thiab cov menyuam raug ntsia tau zoo.

2. Kev hloov siab

Ua ntej, kho tus kws kho hniav siab, uas yuav tsum tau ua tom qab anilox roller tau coated nrog number case. Thaum ua kom ntseeg tau txawm tias tus cwj mem hloov, siv lub caij nplooj ntoos hlav los yog lub ntsuas hluav taws xob los kho cov kab siab mus rau qhov kev pom zoo ntawm 2.8g / cm mus rau 5.6g / cm, ua raws li lub hauv paus ntsiab lus ntawm "yam tsawg kawg nkaus yuav tsum tau siab." Tom ntej no, kho tus cwj mem hloov siab kom lub siab sib cuag ntawm cov menyuam hloov thiab cov menyuam anilox yog 0.2-0.3MPa.

3. Kev xeem khiav

Tom qab mounting ib tug tshiab cov menyuam los yog tom qab kev kho cov cuab yeej loj, siv lub dial gauge los ntsuas lub radial runout ntawm lub anilox roller, xyuas kom meej tus nqi yog tsawg dua los yog sib npaug zos rau 0.025mm. Yog tias nws tshaj qhov ntau, txheeb xyuas cov teeb meem nrog cov bearings, ncej kawg, lossis phab ntsa.

III. Kev soj ntsuam ntau lawm

1. Kev ntsuas kub

Thaum lub sij hawm tsim khoom, siv lub ntsuas kub infrared kom tsis tu ncua ntsuas qhov kub thiab txias ntawm cov menyuam anilox (raws li qhia hauv daim duab 2) kom ntseeg tau tias nws nyob qis dua lossis sib npaug li 35 degree. Yog tias qhov kub ntawm cov menyuam kub siab dhau lawm, nws tuaj yeem ua rau muaj kev hloov pauv hauv cov kua nplaum viscosity, xim inconsistency, thiab ua rau lub hlwb txhaws.

2.Kev Tswj Xyuas Zoo

Nws tuaj yeem muab faib ua kev tshuaj xyuas qhov muag thiab ntsuas ntsuas. Thaum lub sij hawm soj ntsuam pom, cov menyuam nto yuav tsum tau saib xyuas tas li kom paub meej tias txawm tias hloov pauv tus cwj mem, thiab xyuas seb muaj qhov txawv txav xws li streaks lossis ghosting. Kev tshuaj xyuas cov cuab yeej yuav tsum tau ua piv txwv tsis tu ncua ntawm cov ntaub ntawv luam tawm siv lub colorimeter (raws li qhia hauv daim duab 3), nrog rau qhov sib txawv ntom ntom ntawm tib lub phaj tsis pub tshaj 0.3.

3.Scraper System Maintenance

Ua tib zoo saib xyuas qhov xwm txheej ntawm cov scraper kom tsis txhob muaj impurities los ntawm kev sib sau ntawm cov scraper thiab cov menyuam nto, uas tuaj yeem ua rau 'cov nyhuv sandpaper' uas hnav hauv cov menyuam nto. Yog tias kuaj pom cov kab txawv txav, lub tshuab yuav tsum tau nres tam sim ntawd txhawm rau txheeb xyuas cov ntug scraper thiab siab. Nws raug nquahu kom ntxuav cov scraper thiab cov menyuam tom qab kaw ntev lossis thaum lub sijhawm hloov pauv, thiab siv 'lint-dawb daim ntaub' kom tshem tawm cov impurities ntawm ntug scraper, raws li qhia hauv daim duab 4.

4,Kev tuav thiab khaws cia

1. Kov nrog tu

Thaum noj lossis txav cov txheej txheem, ib txwm tuav cov ncej tas nrog ob txhais tes, tuav lawv maj mam, thiab nruj me ntsis tiv thaiv cov menyuam nto ntawm kev sib tsoo lossis rub tawm ntawm cov khoom siv tawv (cov khoom siv, cov cuab yeej, lossis lwm yam rollers).

2. Kev Cia Siab

Rollers yuav tsum tau muab tso rau hauv vertically ntawm ib lub rack siab kom tsis txhob khoov los yog deformation tshwm sim los ntawm muab lawv nyob rau hauv siab. Cov neeg ua haujlwm yuav tsum hnav cov hnab looj tes huv ua ntej kov lub cev rau cov menyuam kom tiv thaiv hws lossis roj los ntawm kev sib kis thiab ua rau cov menyuam ntog. Qhov chaw cia khoom yuav tsum tau qhuav thiab huv si. Nws raug nquahu kom siv cov npog tiv thaiv ntawm qhov chaw ntawm cov qauv chais thaum lub sijhawm siv tshuab, tshem tawm, thiab khaws cia kom txo tau qhov kev pheej hmoo ntawm kev puas tsuaj los ntawm kev sib tsoo.

Vim qhov ntev ntawm cov ntsiab lus, kom nyeem tau yooj yim dua, tus sau tau qhia cov tshooj no ntawm "Cov Lus Qhia thiab Kev Ceeb Toom rau Kev Siv Cov Rollers" thiab vam tias nws tuaj yeem pab tau. Hauv qhov teeb meem tom ntej no, peb yuav ua tib zoo saib yuav ua li cas thiaj tswj tau cov qauv chais kom zoo.
