Nheyo Inoshanda Yemuchina Wekudhinda

1. Nheyo yekushanda kwemuchina wekudhinda wechidzitiro. Tichitora muchina wekudhinda wechidzitiro wakagadzirwa nemaoko, nhungamiro yekushanda kwemuchina wekudhinda wechidzitiro inogona kutsanangurwa seinotevera: simba rinopfuudzwa kuburikidza ne transmission mechanism, kuitira kuti squeegee isvine inki ne screen printing plate zvichifamba, kuitira kuti screen Printing plate ne substrate zvigadzire impression line. Nekuti screen ine tension N1 na N2, inogadzira simba F2 pa squeegee. Kusimba kunoita kuti screen printing plate isabatane ne substrate kunze kwe impression line. Inki iri kubata ne substrate. Pasi pe action ye squeegee force F1 ye squeegee, printing inobuda kubva pa moving embossing line kuenda ku substrate kuburikidza ne mesh. Munguva yekudhinda, screen printing plate ne squeegee zvinofamba zvichienderana, uye pressing force F1 ne resilience F2 zvinofambawo pamwe chete. Pasi pe action ye resilience, screen inodzoka nenguva kuti ibve pa substrate kuitira kudzivirira Blot rakasviba. Kureva kuti, sikirini inogara ichichinja chimiro uye ichidzokororwa panguva yekudhinda. Squeegee inoparadzaniswa ne substrate pamwe chete ne screen printing plate mushure mekunge kudhinda kwe one-way kwapera, uye panguva imwe chete, inodzokera ku inki kuti ipedzise kudhinda. Daro riri pakati pepamusoro pe substrate ne reverse side ye screen printing plate mushure mekunge inki yadzoserwa rinonzi same-page distance kana screen distance, iyo inowanzo kuve 2 kusvika 5 mm. Mukudhinda nemaoko, matekiniki nehunyanzvi hwemushandisi zvinokanganisa zvakananga kuumbwa kwe impression line. Mukuita, vashandi ve screen printing vakaunganidza ruzivo rwakawanda rwakakosha, izvo zvinogona kupfupikiswa muzvikamu zvitanhatu, kureva, kuona kuti straightness, uniformity, isometric, equalizing, centering uye vertical edge iri kufamba kwe squeegee. Nemamwe mashoko, squeegee board inofanira kufamba yakananga mberi panguva yekudhinda, uye haigone kufamba kuruboshwe nekurudyi; haigone kunonoka pamberi nekukasira kumashure, kunonoka mberi nekukasira kumashure kana kamwe kamwe kunonoka nekukasira; kona yekutsvedza yebhodhi reinki inofanira kuramba yakafanana, uye kutarisisa kwakakosha kunofanira kupihwa kuti kukunde kona yekutsvedza. Dambudziko rinowanzoitika rekuwedzera zvishoma nezvishoma; kumanikidzwa kwekudhinda kunofanira kuchengetedzwa kwakaenzana uye kwakafanana; daro riri pakati pechinhu chinotsvedza nemativi emukati efuremu rechidzitiro rinofanira kuenzana; ndiro yeinki inofanira kunge yakatarisana nefuremu.
