Electronic shaft rotograuvre printing machine

Functions and characteristics of Ruiguang electronic shaft rotograuvre printing machine

Of brand electronic shaft driving the gravure printing machine is a high technological content of a new generation of sophisticated equipment, its innovative point is that it has a unique technology, the performance is as follows: the whole machine for the drum type base material (such as plastic film, paper, etc.), high performance without a shaft (electronic axis) combined, can also apply to water-based ink and solvent-based printing ink, printing preparation time is short, fast startup, rapid and accurate pre set, printing speed stability, high accuracy, high product quality, low residual solvents (use of solvent-based inks), low noise, can be significant energy saving, and many other advantages. It can complete the high-precision AC servo drive and control system of plastic film or paper coil at one time, independent servo motor drives the plate roller to run synchronously and complete the longitudinal color register function, reduce the length of the empty material route between the units and the time of paper passing, which is conducive to accurate overprinting. The unique version of the roller drive and phase compensation calculation, horizontal automatic budget algorithm in acceleration and deceleration mode can also obtain qualified registration. The color group waste discharge device reduces the harm of solvent to human body. The ink circulation is closed ink-pouring or frequency conversion ink-transferring. The drying waste heat is recycled through the double-flow plate-tooth heat exchange system.

Ruiguang electronic shaft drive gravure printing press has achieved a major breakthrough in the printing technology of Chinese gravure printing press, and marks the manufacturing capacity of high-speed electronic shaft (shafless) drive gravure printing equipment in China, which has approached and reached the world's advanced level.

At present, Ruiguang electronic shaft gravure printing machine has been widely used in the high-end market of printing flexible packaging industry with its advantages of high speed, precision and high rate of return.

The main difference between the mechanical shaft and the electronic shaft of a gravure press is the color set. The mechanical shaft is aligned by a hundred precision ball screw. Each color set of the electronic shaft is driven by a servo motor to drive the plate and the servo motor completes the nesting function; The electronic axis is recommended because each color set of the electronic axis has a servo motor, so it also has the function of secondary alignment. And the electron axis factor is faster.

This machine is suitable for multi-color continuous printing of BOPP, PET, PVC, PE, aluminum foil, web and other coiled film materials with excellent printing performance. It is widely used in all kinds of high quality printing
