4 Colors 250m/min gear sleeve cylinder Central Drum Flexographic Printing Machine

Lisheng Paper Bag Ci Flexographic Printing Machine Central Drum 4 Color Flexo Presses
 
 
Use:
This central impression (central drum) flexographic printing machine is suitable for printing such packing materials as polyethylene, polyethylene plastic bag, leather, glass paper and roll paper etc. And it is a kind of ideal printing equipment for producing paper packing bag for food, supermarket handbag, non-woven bag, vest bag and clothes bag, etc.

Characteristics:
1.Reasonable structure, advanced technology, easy operation, stable performance, accurate color register.
2.Adopting high-quality motor, high-quality inverter, save the electricity, reduce the run fluctuation.
3.When the machine is stopped working, printing rolls still keep moving; when rise the printing roller,
ink motor running automatically ;when fallen the printing roller, ink motor stop running automatically.
4.The machine is equipped with blower and heater; and the heater employed central temperature control system.
5.The use of individual drying oven and cold wind system can effectively prevent the ink adhesion after printing.
6.Roller adopts special steel processing, and through special treatment, greatly reduce the beating range.
7.Printing roller uses static balance and dynamic balance processing, hard anode oxidation treatment, small resistance, 
beating small, achieves finally perfect printing effect.
8.Accurate printing effect achieved by special gear transmission device.
9.The printing machine all can choose advance configurations to achieve the high quality, the high-definition effect.
