The utility model is a blocking type scraper device used for reducing plate roll exposure in the process of printing, including a fixed frame, a fixed frame including two vertical plates with parallel settings, and a plate and a sealing scraper mechanism between the two vertical plates. The sealing scraper mechanism includes two telescopic cylinders and two telescopic cylinders are fixed in respectively. On the inner wall of the two vertical plates, the end of the telescopic rod of the telescopic cylinder is connected with a vertical fixed plate, and an arc baffle is arranged between the two vertical fixed plates. The left and right ends of the arc baffle are equipped with a rotating mounting shaft and are mounted on the two vertical fixed plates through the rotating mounting shaft, and the rotating mounting shaft is fixed with two vertical fixations. A fastening device is provided at the junction of the fixed plate. The fastening device is provided with a fastening pin. The front and rear ends of the arc baffle are provided with a scraper mounting plate, and a scraper is installed on the scraper mounting plate. The utility model seals the plate roller, greatly reduces the exposure of the roller, reduces the volatilization of the solvent, and reduces the splash of the ink spot. One

一种印刷过程中减少版辊裸露用的封挡式刮刀装置
本技术涉及密封刮刀领域,尤其涉及一种印刷过程中减少版辊裸露用的封挡式刮刀装置。
技术介绍
目前软包装行业对环保的要求越来越高,除了对外排放的VOCs气体要求处理外,对车间内部的溶剂挥发也提出了要求。印刷过程中版辊因高速旋转,增加了油墨或胶水的挥发;印刷过程中因版辊的过度裸露,容易甩墨点到印刷膜上,造成印品不良。
技术实现思路
本技术旨在解决现有技术的不足,而提供一种印刷过程中减少版辊裸露用的封挡式刮刀装置。本技术为实现上述目的,采用以下技术方案:一种印刷过程中减少版辊裸露用的封挡式刮刀装置,包括固定架,所述固定架包括左右两个平行设置的立板,两个立板之间安装有版辊和密封刮刀机构,所述密封刮刀机构与所述版辊等高设置,所述密封刮刀机构包括两个伸缩气缸,两个伸缩气缸分别固定在两个立板的内侧壁上,所述伸缩气缸的伸缩杆面向所述版辊,所述伸缩气缸的伸缩杆末端连有竖直固定板,两个竖直固定板之间设有弧形挡板,所述弧形挡板的弧面半径与所述版辊的半径一致,所述弧形挡板左、右两端设有旋转安装轴并通过所述旋转安装轴安装在两个竖直固定板上,所述旋转安装轴与两个竖直固定板的连接处设有紧固装置,所述紧固装置上设有紧固销,所述弧形挡板前、后两端设有刮刀安装板,所述刮刀安装板上安装有刮刀。所述弧形挡板的上表面成弧面且弧面的半径与所述版辊的半径一致,所述弧形挡板的下表面成平面。所述弧形挡板下表面的左右两端设有两个互为镜像的连接板且右端的连接板呈7字形,所述旋转安装轴固定在所述连接板的竖板和竖直固定板之间。本技术的有益效果是:本技术对版辊进行了密封处理, ...
