Abstract

The invention discloses flexographic printing equipment with high fitting degree and a printing method, and belongs to the field of flexographic printing equipment. The invention discloses high-fitting-degree flexographic printing equipment and a printing method. The high-fitting-degree flexographic printing equipment comprises a letterpress printing cylinder, a buffer layer, a supporting layer impact part, a roller core and a friction part. The letterpress printing cylinder, the buffer layer and the supporting layer are all cylindrical and are sequentially nested and fixedly arranged from outside to inside, a heating cavity is formed in the supporting layer, and the roller core is fixedly installed in the heating cavity in the axial direction of the supporting layer and coincides with the axis of the supporting layer. The letterpress printing cylinder is axially and rotatably mounted at the mounting position of the letterpress printing cylinder of the flexographic printing equipment, vibration is generated through impact of the impact plate and the supporting layer and is transmitted to the letterpress printing cylinder through the buffer layer, so that printing ink is quickly separated from the letterpress printing cylinder through slight vibration during printing of the letterpress printing cylinder, the utilization rate of the printing ink is increased, and the printing efficiency is improved. And meanwhile, the printing quality is improved.

Description

technical field [0001] The invention relates to the field of flexographic printing equipment, in particular to a flexographic printing equipment and a printing method with high adhesion. Background technique [0002] Currently in the printing industry, one of the main directions representing the future development of printing technology is flexographic printing. Flexographic printing has attracted widespread attention due to its advantages of environmental protection, high production efficiency, and high precision. Common flexo printing equipment currently on the market generally includes a frame and a relief cylinder, impression cylinder and ink cylinder mounted on the frame. [0003] Due to the defects in the frame structure provided in the prior art, the traditional relief cylinder transfers ink through the ink cylinder, and then presses the ink to the surface of the material under the combined action of the impression cylinder. At this time, the degree of fit of the tw...
