metal sheet four-color offset printing machine

The main transmission gear is located in the protective cover of the machine, which is fully lubricated and has a long service life; 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 is advanced, and the operation Convenient; using shaftless transmission technology, each color group is independent of each other, and can be installed on the plate and wipe the cylinder at the same time;
Introduction


Technical performance:

● The main transmission gear is located in the guard of the machine, with sufficient lubrication and long service life;

● The three printing cylinders are arranged vertically, which is easy to operate;

● The printing cylinder is supported by imported precision bearings to ensure the rotation accuracy of the cylinder;

● Advanced roller pressure adjustment structure, easy to operate;

● Adopting shaftless transmission technology, each color group is independent of each other, and can be loaded with plate and wiped cylinder at the same time;

● The synchronous transmission technology is adopted between the color groups, and the virtual main axis is used as a reference to achieve high-precision synchronization;

● The cylinder adopts the hard lining method, and the printing dots are strong and clear;

● It adopts cam high-point closing teeth, reliable positioning and accurate overprinting;

● The plate cylinder adopts alcohol dampening, and the printing ink is bright;

● The clutch of form roller and drum is driven by air cylinder, with simple structure and reliable operation;

● The water fountain roller and the ink fountain roller are driven by separate frequency conversion motors, which can be adjusted steplessly to achieve synchronous tracking with the speed of the main machine;

● Scientific and reasonable arrangement of ink rollers ensures the quality of ink supply in the system;

● The drive of the ink supply system and dampening system can be disconnected from the main machine as needed to avoid dry wear of the rubber roller;

● Man-machine interface, intuitive screen, easy to grasp, easy to operate;

● The synchronization between the feeder and the main machine can be adjusted electrically without stopping the machine, effectively shortening the auxiliary time;

● It adopts fixed-point, quantitative and timing lubrication system, which ensures sufficient lubrication without oil leakage.
