NOVELTY - The utility model claims a baffle-type coating groove, comprising: bottom plate; one end of the bottom plate is provided with a hinge; the lower part of the other end is provided with a supporting rod; the front plate, the front plate is set on the front side of the bottom plate; back plate; the back plate is set on the back side of the bottom plate; a first guide roller; the first guide roller is set on one side of the hinge; a flexible pad; the flexible pad is paved on the upper surface of the bottom plate; covering the first guide roller; a bottom plate, a front plate, a rear plate; the first guide roller and the flexible pad form a groove for containing the coating; the middle position of the groove is provided with a baffle. Compared with the existing technology, the baffle-type coating groove provided by the utility model can make the groove respectively the first groove and the second groove, reduces the coating height of the coating port, besides, the paint absorbing part of the height difference through the suction port, reduces the height difference of the coating port; ensuring the graphene oxide slurry coating uniformly on the substrate.
