The utility model relates to a coating regulator of a coater for producing liquid crystals, which belongs to equipment for producing liquid crystal displays. The lower side of a fixed wall plate 11 is provided with a supporting roller 19 through a bearing; a movable wall plate 23 is arranged on the fixed wall plate 11 through guide pillars 10 and 20 and a feed screw nut driving mechanism; the movable wall plate 23 is provided with a coating roller 21; the coating roller 21 is positioned on the right upper side of the supporting roller 19. The utility model is characterized in that the movable wall plate 23 is also provided with a sliding bar component 14; a dovetail sliding block 18 of the sliding bar component is provided with an equalizing roller 22; a slope angle of a connecting line of two shaft centers of the coating roller 21 and the equalizing roller 22 is from 18DEG to 22DEG. The utility model has the advantages that a dial test indicator faces to an operating desk, and therefore, the operation is convenient and visual; a pretightening force of the sliding bar component 14 is adjustable, and therefore, the coating roller is not easy to move; the uniformity and the stability of the coating thickness are raised; the adjustment is convenient and quick to control the thickness of a film.
