Dispensing plate roller, diaphragm and gluing device

The invention discloses a dispensing plate roller, a diaphragm and a gluing device.The dispensing plate roller comprises a cylindrical cavity, a plurality of protruding points are formed on the surface of the cylindrical cavity, and the protruding points are arranged according to a hexagonal structure and located at the corners of the hexagonal structure; the surface of the cylindrical cavity is connected according to the convex points to form an arc-shaped honeycomb structure, and the regular hexagon is bent along the surface radian of the cylindrical cavity to form an arc-surface hexagon which is the hexagonal structure. The diaphragm comprises a base membrane, a plurality of coating points are formed on the surface of the base membrane, the coating points are arranged according to a hexagon, and the coating points are located at corners of the hexagon, so that a honeycomb structure can be defined on the surface of the base membrane by connecting lines after the coating points are connected.
