Further improvement lies in that the printing plate uses roller concave surface printing plate, and the pressure printed is controlled in 4.5-4.8Mpa.
Further improvement lies in that the drying and processing specifically uses the drying mode of mid-frequency induction heating, and heating temperature At 55 DEG C to 60 DEG C.
A kind of paper package box gravure printing apparatus, including paper feeding mechanism, printing mechanism and the rolling-up mechanism set gradually；
There are a several groups in the printing mechanism, every group of printing mechanism include ink tank, roller printing plate, doctor, print roller and Drying oven, the roller printing plate be set to ink tank in, the doctor be set to roller printing plate side, and the edge of a knife of doctor with The contact of roller printing plate, the print roller are set to the top of roller printing plate, and the contact of certain pressure is kept with roller printing plate, described Drying oven is mid-frequency induction heating drying oven, is set on the paper delivery channel of every group of printing mechanism.
Further improvement lies in that the doctor is made of operator and edge knife, it is described to operate and the contact of roller printing plate Angle is 40 ° -45 °, and the edge knife is connected at the both sides of the edge of operator.
Further improvement lies in that the edge knife is made of nanometer silicon dioxide material.
Further improvement lies in that the surface of the edge knife is covered with mushroom projection.
Further improvement lies in that the clearance distance between the hat body diameter of the mushroom projection and adjacent mushroom projection The ratio between be 1.5:1.
The beneficial effects of the present invention are: in printing ink it joined a variety of materials for increasing viscosity and with faint scent The raw material of smell, such ink is in printing process, and more preferably, and there is no bad smells for clarity, and toxic object is also not present Matter volatilization；In printing technology by the way of mid-frequency induction heating, heating and temperature control is more stable, the effect after making printing More preferably, it using the process of wiping and venting, avoids doctor and carries the blank parts that ink is dropped in plate surface again, Further improve the quality of intaglio printing.
