The invention relates to a multifunctional coating mold head. The multifunctional coating mold head comprises a mold head frame and a mold head; the mold head frame comprises an upper cavity shell anda lower cavity shell; the upper cavity shell is connected with the lower cavity shell through a rotating shaft; the lower end of the lower cavity shell is tightly connected with the mold head; the mold head is connected with a coating roller through a limiting piece; and a key shaft inserted in the center of the coating roller is connected with an adjusting mechanism. After the structure is adopted, the multifunctional coating mold head structurally adopts an overturning and folding integrated mold head structure to greatly improve the sealing performance compared with the prior art. The upper cavity shell and the lower cavity shell at the top end of the device can quickly refine pulp to distribute to an output end of the mold head. When the output of the pulp is needed to increase, an air pump can apply pressure to the pulp to accelerate the flowing speed of the pulp. During coating by the mold head, the coating roller can be controlled by the adjusting mechanism to further limit a gap between the coating roller and the coating roller.
