1. Back kicking style automatic feeding paper system, caccum absorption paper help feeding paperboard,precision and reliable. 2. CAD mould piece design, The multi-color printing machine unit can be combined in anhy way . 3. Adopt high-precision phase adjusting configuration, print plate adjusting is easier. 4. The slot knife adopt electrical link adjusting ,adjust the four knives to the position at same time, slotting and rolling can moving simutaneously,adjust quickly. 5. With 45#forging-works and quench treatment the drive gears have increased the durability and life, and greatly guaranteed the precisionof process printing. 6. The paper-feeding of the drive part of the printing part adopts cross aliding drive.The gears of the print pressing roller and the paper-catching roller adopt the planetary rocker-plate drive device. The gears are normally meshed from beginning to end while the space between the print pressingand the paper catching is adjusted, which does not enlarge the space between the gear-top and gear-side,make the color process (esp,the multi-color process)more accurate and lower the waer accurate and lower the wear between the gears to the minimum. 7. The phase part adopts360°adjusting while stop working or during working, The scale will display this two kinds of adjustment which are different from the current phase adjusting,i.e.the driving and jointing part of the large gear adopts 2bearings to suppor and joint, which has preveted the sleeve joint of the current gear and the inside-gear-circle from the ends-and-surface moving up and down, easy to lock, short service life and other defects. And the adjusting part adopts the planetary, worm wheel and worm driving method, which has greatly enlarged the drive moment and raised and raised the accuracy of adjusting.
