TECHNICAL FIELD

[0001] The utility model relates to the technical field of tissue paper drying cylinder, especially to coating device for tissue paper drying cylinder. BACKGROUND

[0002] Tissue paper creping technology is a unique process of tissue paper compared with other paper, and is also a key technology to give tissue paper water absorption and softness. Tissue paper creping technology is divided into three types: wet creping technology, semi-wet creping technology and dry creping technology.

[0003] Dry creping technology is to dry the wet paper web to about 6% moisture on the surface of the drying cylinder, through the matching of coating and creping doctor blade, the dry and flat paper web hits the creping doctor blade, the paper web is folded to form wrinkles, at the same time, the combination between fibers is destroyed, the combination between fibers becomes weak, and the paper web becomes fluffy, so as to become soft and strong in absorbency. In this process, the creping doctor blade also needs to be matched with coating to get better products. The coating of dry creping is a special film formed by evaporating water in the coating mixed with water through the coating pipe nozzle and then curing under high temperature of the drying cylinder. This coating helps the wet paper web adhere to the cylinder surface when the paper web is transferred from the felt to the cylinder surface, dries better on the cylinder surface, and assists the paper web to separate from the cylinder surface when hitting the creping doctor blade. By improving and optimizing the coating pipe, the amount of coating per ton of paper is reduced.
