Description

Paperboard printing and coating mechanism

Technical Field

The invention relates to the field of paperboard printing, in particular to a paperboard paint printing mechanism.

Background

The existing cardboard hard-brushing method is generally used for printing patterns on the surface of the cardboard by rubbing the attached pigment onto the surface of the cardboard by a paint roller. When the paint is attached to the paint roller, the paint in the hopper is directly coated on the surface of the paint roller after the paint roller rotates, or the paint is attached by abutting against a corresponding feed roller, and then printing is carried out.

The surface of the existing paint roller is provided with a convex die, and pigment is printed on the paperboard through the convex die, but when the pigment is attached to the paint roller, the side wall of the paint roller is also attached with the pigment, and when the paperboard is printed, the pigment on the side wall of the paint roller is coated on a non-printing position of the paperboard or is thrown off to the rest position of the paperboard.

Therefore, there is a need for an improved structure that overcomes the above-mentioned deficiencies.
