Description

Technical Field

[0001] The utility model belongs to the technical field of paper production equipment, and particularly relates to a two-end spraying type paper surface spraying device. Background Art

[0002] The paper surface spraying device is mainly used for spraying chemical additives, glue and coating on the paper surface to give the paper certain specific properties. Traditionally, a certain chemical raw material is applied to the paper surface by a surface glue machine.
