Main Features Of The Machine
The whole machine is controlled by bus technology to realize logic control and protection;
Dc busbar feeding technology is used to reduce energy consumption of equipment;
5 Closed-loop tension control and display;
External double-station rewinding and unwinding unit;
Coating film, lamination film with EPC correction;
Heavy pneumatic doctor scraper;
Coating pressure roller and the coating roller are driven separately to prevent the film from sliding between the coating pressure roller and the coating roller;
Gravure coating roller trolley;
In order to improve the coating flatness of coated surface and increase the transparency of composite film, a coating roller is arranged;
The whole length of 10.8 meters is high efficiency and energy saving detachable porous plate and slot air mouth desiccant structure;
The rewinding tension is set by the tapering tension setting device of any feeding on the touch screen, and a variety of feeding tension curves can be set arbitrarily to obtain the ideal feeding effect.
After the improvement of the material receiving part receiving structure, can minimize the automatic feeding process in the paper tube core of the crumple and other waste.
