Technical performance: The main transmission gear is located in the protective cover of the machine. The lubrication is sufficient and the service life is long; the three printing cylinders are arranged vertically, which is easy to operate; the printing cylinders are all supported by imported precision bearings to ensure the rotation accuracy of the cylinders: the pressure adjustment structure of the plate roller Advanced, easy to operate: Shaftless transmission technology is adopted, each color group is independent of each other, and the plate and wiper cylinder can be installed at the same time; synchronous transmission technology is adopted between color groups, and the virtual main axis is used as a reference to achieve high-precision synchronization
