[0002] The full name is melamine impregnated film paper, also known as "melamine" paper. It is a kind of plain base paper or printed decorative paper that has been impregnated with amino resin and dried to a certain degree. It has a certain resin content and volatile matter content. The impregnation liquid may accumulate during the impregnation process of the decorative paper, thus affecting the impregnation practicality of the impregnation liquid.

[0003] In the prior art, a Chinese patent document with publication number CN114000373A is proposed to solve the above technical problems. The technical solution disclosed in the patent document is as follows: an impregnation device for producing decorative paper, wherein a first guide device for guiding the impregnation of decorative paper is fixedly installed inside the impregnation box and at the bottom of the top plate, and a first mixing device that can swing up and down is fixedly connected inside the impregnation box and at a position corresponding to the first guide device.

[0004] In order to solve the problem that the impregnation liquid may accumulate during the impregnation process of the decorative paper, thereby affecting the impregnation practicality of the impregnation liquid, the prior art uses two sets of mixing devices to cooperate with each other for impregnation.
