Description

Technical Field

[0001] The utility model belongs to the technical field of air knife coating, in particular to an air knife coating device of a printing machine. Background Art

[0002] The air knife coating device is a coating machine composed of a single-roll paper coating machine and an air knife. The coating roller applies the coating to the substrate, and the airflow from the air knife blows away the excess coating to adjust the coating thickness and make the coating surface smooth. It is suitable for coatings with high solid composition and low purity, such as water-soluble coatings and organic sols. It is mainly used to manufacture high-grade printing paper, recording paper, latex-type photosensitive paper, etc.

[0003] However, during the use of the existing air knife coating device, the air knife is fixed at a specified angle. When the angle of the air knife is adjusted again, the air knife needs to be disassembled and reassembled. The angle adjustment method is too cumbersome, which affects the work efficiency. At the same time, the paint is stationary for a long time, and the paint surface is prone to crusting, which affects the finished product of the coating. Utility Model Content
