· Can be continuous or skip paper (with counter).

· It adopt the lead edge roller to feed, can adjust the route, to ease the pressure on drawing paper roll.

· Lead edge feeding increase the section flow rate to make feeding smoothly and accuracy.

· Frequency conversion control vacuum air flow and pressure, to match the board size.

· Paper glue roller for double glue, soft inner and outer hard, keep the inner elastic and guarantee the surface wear resistance, reduce the cardboard was be squashed to be be sent in.

· Dust cleaning device:The brush and blower to remove cardboard surface confetti. Multiple fan straight smoke added electrostatic brush and turning round brush, the greatest degree remove dust board surface.

· About paper roller clearance, the position of the left right bar is adjusted by computer.

· Equipped with brush device to sufficiently eliminate dust and scraps as well as foreign substances on the printing surface and to improve printing quality.

· Scroll hanging version, locking 360 degrees, let operation of hanging plate is simple, more accurate registration.

· Changing plate quickly,it can fix the incline error when paste the plate, so that reach to the range of amendment.

· Adopting vacuum absorb and high precision to convey, high topping precision.

· The fixed group be widen in printing unit, it can help dry the ink, to guarantee the topping precision.

· Printing roll phase adopt servo motor to drive, can connect to the Endat high precise encoder, guarantee the control precision of the servo drive system, topping-control contact to the servo directly, quick response and high precision.

· The transverse phase, computer and electric-digital control.

· Imported brand scraper ink system: ink cavity body for non-metal material, special never rust, easy to clean;Rapid change around the blade.

· Adopt automatic cleaning-switching device. Let the ink recycling more thoroughly and save the ink, when clean or change the color of the ink, can save ink 0.4-0.5kg per unit once.

The fixed group be widen of the polishing unit, it can help speed up the oil-dry.

· You can adopt water base or UV varnish to polish when the polishing unit works, also to use as printing unit.

· Equipped with card sensor to make the operate safe and reliable.

· With servo motor driving, guarantee not effect the printing precision.

· Drying unit can adopt Infrared or ultraviolet light system.

· According to the wide of paperboard, you can segment control infrared lamp, energy saving.

· UV drying method can dry the UV oil of presswork quickly, Avoid phenomenon of tow flowers die cutting,At the same time effectively improved the product printing speed.

· With the servo motor drive,guarantee the shake of printing unit is few, to make print accurate.

· Rubber gasket roll compensation is controlled by independent motor drive, rubber mat roller speed, compensation scope± 3.5 mm, make the rubber gasket roller and die cutter roller speed is consistent.

· Rubber gasket roll machine screw reversing 50 mm winding device, improve the service life of the rubber gasket.

· Transverse phase, computer and electric control, digital control in the plus or minus 10 mm.

· Die-cutting phase adjustment by PLC, servo drive.

· The structure of the rubber gasket roller, keep the rubber gasket surface is flat and level.
