Inline Flexo Printing Presses
Language
Offset and flexo unit combination.
Enhanced stabilization with shaftless drive.
Optimized print management and machine adjustment.
DBJR 320 modular multi-function rotary printing machine is ideal for a variety of substrates from 0.02mm to 0.35mm including paper, film, metal foil, cardboard and other materials. The wide range of printable substrates makes this a very versatile machine.
◪
Offset and flexo unit combination
The ink fountain and the ink feed roller of the offset printing unit are controlled by the cooling water thermostat to maintain the stability of ink viscosity. The flexo unit with anilox sleeves makes sleeve changing quick and easy. Flexo printing can be applied to any printing station through the shared platform technology.
◪ Enhanced stabilization with shaftless drive
From unwinding to printing, die-cutting to rewinding, the whole machine uses servo drive technology. The printing tension is controlled by a closed-loop tension control system which is driven by a servo motor. All the offset printing cylinders (plate, blanket and impression), rubber cylinders and ink and water rollers are driven by separate servo motors for better stability.
◪
Optimized print management and machine adjustment
Magnesium aluminum alloy plate and blanket sleeves make changing sleeve sizes quick and easy. Similarly, the printing format can also be changed easily. Using the PMC Print Management Center, the machine parameters can be adjusted at any time through the digital controller. In addition to those functions, the print jobs can be stored and recalled to set the machine for the next job, making it very operator friendly.

1、 The whole machine adopts the latest servo control system Baumuller from Germany and each printing unit is driven by independent servo motor .there are 21 servo motors in total for 8 color machine which ensure the accurate registration during high speed running .every printing unit has two servo motor
2、 The printing roller adopts sleeve system which is light, easy, convenient and fast to change .This type of design is largely improve the printing quality and reduce the maintenance .
3、 Fast and easy pressure adjustment of printing or ink transferring :printing roller run by bearer, it is not necessary to adjust the pressure when change the roller, or at most fine adjust for special job.
4、 Anvil roller equips with water chiller, it’s good for film material as well
