Material feeding 2.0 (ton) Power of main motor 15KW+15KW Capacity of air pump 140/ (m3/hr) Dimension of press(LWH) 1130028002460mm 3. Main Technical Performance 1)Three printing cylinders are arranged vertically for easy operation; 2)Quick gripper for printing plate and rubber cloth to reduce lead time; 3)Drive system of ink/water supply can be separated from the main motor to avoid dry abrasion of the rubber roller; 4)Advanced structure for dynamic pressure adjustment of water/ink roller makes easy operation; 5)Position of pusher is adjusted by motor with easy operation and high efficiency; 6)Automatic adjustment of synchronization between feeder and main motor by easy operation of push button; 7)Shaft-less drive is used. Two printing couples are controlled by individual servomotor so they are independent. 8)Synchronized optic cable between printing couples, through virtual main axis as reference, makes the two servomotors quite synchronized. 9)Printing precision is enhanced by synchronized servomotor with low inertia, high output torque, quick dynamic response, smooth run and low noise. 10) Main drive device with simple structure has only one communication bus to connect PLC and is easy for service; 11) All cylinders/rollers and delivery device and double sheet ejector are coupled pneumatically featuring simple structure and easy operation; 12) Water/ink duct rollers are controlled separately by frequency converter for continuous speed change, and are synchronized/traced with main motor; 13) Reasonable and advanced arrangement of water/ink rollers guarantees printing quality; 14) All three big cylinders use advanced high precision bearing support to ensure quality printing; 15) Hard lining structure ensures solid screen dot; 16) High point closing of jaws with strong gripping force and reliable transfer; 17) Sheet transfer by imported electronic device and standard air cylinder features simple structure and accurate transfer; 18) Stock lift mechanism is operated by worm wheel and chain wheel with strong load capability and without slip; 19) No-sheet detector for stock controls the air pump operation and holds back the stock lift.
