网框调位装置
本技术涉及丝网印刷领域,尤指一种网框调位装置。
技术介绍
丝网印刷是指用丝网作为版基,并通过感光制版方法,制成带有图文的丝网印版。丝网印刷由五大要素构成,丝网印版、刮板、油墨、印刷台以及承印物。利用网版图文部分网孔可透过油墨,非图文部分网孔不能透过油墨的基本原理进行印刷。印刷时在网版的一端倒入油墨,用刮板对网版上的油墨部位施加一定压力,同时朝网版框另一端匀速移动,油墨在移动中被刮板从图文部分的网孔中挤压到承印物上。印刷之前,需要先调整网框(网版)的位置,即调整网框在水平面内前后移动及左右移动,使网框图文部分网孔对准印刷位置,否则会出现印偏现象。而现有的网框调位方法,一般先松开锁紧螺杆,将网框沿底架的滑杆移动,调整好位置后再锁死锁紧螺杆来固定网框。当需要微调以准确定位时,必须反复松紧锁紧螺杆来实现。此种调位方法动作繁琐,费时费力,操作不便,导致工作效率低下。
