1. The flexographic printing press consists of 4 parts, ie unwinding feeding parts, printing parts, drying parts and rewinding receiving parts. In modern flexo printing presses, there are generally tension control, edge position control, register control, print observation and other measurement and control devices and mechanical condition monitoring and fault diagnosis systems. In addition, in order to expand the scope of application, some flexographic printing machines are also equipped with glazing, laminating, bronzing, slitting, die-cutting, punching, screen printing, and gravure printing units and other devices to become a flexographic joint. production line.

2. The flexographic printing speed generally reaches 150m/min (or even higher). Under normal operating conditions, the unwinding feeding device must be installed in order to reduce the number of stoppages and the waste of the reel material. The function of the unwinding feeding device is to unwind the rolled printing material, continuously and stably convey the printing material to the printing part, and control the speed, tension and lateral position of the printing material before the printing material reaches the first printing part. The unwinding feed member has a feed roll holder and a set of guide rollers, and the feed roll holder is arranged in a straight line on the printing member. The reel rack has electric or hydraulic components to control the lift. Generally, the axis of the paper roll is locked by pneumatic components, and the detector is installed at the end of the paper roll.
