Roller printing device for continuous coating of moisture-absorbing response material

Abstract

The utility model discloses a roller printing device for continuous coating of a moisture absorption response material, and belongs to the technical field of coating printing equipment. The cylinder printing apparatus includes: a cylinder printing unit including a main cylinder and an impression cylinder cooperating with the main cylinder, the main cylinder being provided with a gravure pattern accommodating a moisture-absorbing response material, the moisture-absorbing response material being coated on a base material by rotation of the main cylinder and the impression cylinder; the base material conveying unit is used for continuously conveying the base material to the roller printing unit; and a coating material supply unit for supplying the moisture absorption responsive material to the cylinder printing unit. The gravure pattern is arranged on the main roller, so that the problem that the permeation amount of the moisture absorption response material is difficult to accurately control is solved, continuous coating can be realized in cooperation with the base material conveying unit, the coating material supply unit and the like, and the uniformity of a high-viscosity material of the moisture absorption response material in transfer printing is ensured.
