sps stop cylinder wire printing machine
1. high precision stainless steel printing cylinder
(1) in addition to the unique groove design, exquisite flattening treatment, and the built-in paper holder located in the cylinder, there is an additional gap between the plate and the surface of the roll during the inking process to complete the paper feeding positioning and realize "zero distance" printing. Extremely low squeegee pressure is used to obtain minimal version deformation and achieve perfect image reproduction accuracy
(2) the exquisite automatic conversion design of vacuum suction and high-pressure blowing not only ensures the precise pasting and movement synchronization of the paper and the drum in printing, but also ensures the rapid and smooth stripping of the paper from the roll after printing.
(3) the strict machining accuracy ensures the accuracy and roundness of the surface of the Jane
(4) excellent stainless steel materials are used to ensure the high quality and durability of the drum
2. Precise rubber scraper control system
