The invention discloses a uniform gluing device based on the processing of casual shoe fabrics, and the invention relates to the technical field of gluing devices. Since the glue is in a colloid state and has poor fluidity, the speed of downward flow under its own gravity is slow, and when the material passes through at a fast speed, the glue cannot be coated on the surface of the material. The uniform gluing device based on the processing of casual shoes cooperates with the gluing roller through a rubber gasket. During the upward movement of the gluing roller, the gap between the gluing roller and the glue groove is opened, so that the glue flows downward along the gap under its own gravity, and at the same time, the glue is evenly coated on the surface of the material in cooperation with the rotation of the gluing roller. At the same time, when the gluing roller moves up, the rubber gasket is squeezed, so that the groove roller rotates with the gluing roller, driving the upper layer of glue to move downward, so as to prevent the glue itself from being in a colloid state and having poor fluidity, resulting in obstruction of outflow, and being unable to be evenly coated when the material passes through.
