By adopting this structure, four groups of coating devices 2 are arranged on the frame 1, and each group of coating devices 2 is composed of a coating roller 21, a transfer roller 22, a guide roller and a pressure roller 23. That is, two draws (4 sheets) of base paper can be coated with cream on the coating equipment at the same time, so that the wood pulp base paper or bamboo pulp base paper can achieve the function of frosted paper, which greatly improves the work efficiency.

[0026] like Figure 1 and Figure 2 As shown, four groups of coating devices 2 are evenly spaced along the height direction of the frame 1. With this structure, by reasonably setting the distribution mode of the coating devices 2, the coating devices 2 can simultaneously perform cream coating treatment on 2 draws (4 sheets) of base paper, which greatly improves the work efficiency.

[0027] like Figure 1 and Figure 2 As shown, the frame 1 is rotatably connected with a first guide roller 25 and a second guide roller 26, the first guide roller 25 is located on the left side of the coating roller 21, and the second guide roller 26 is located on the right side of the coating roller 21, and the upper surfaces of the first guide roller 25 and the second guide roller 26 are both lower than the upper surface of the coating roller 21.
