The invention discloses a ceramic tile stacking machine, which comprises a base, a tile selecting mechanism, a clamping and ascending mechanism, a turning mechanism and a conveying mechanism, wherein the tile selecting mechanism, the clamping and ascending mechanism, the turning mechanism and the conveying mechanism are arranged on the base, the tile selecting mechanism is used for selecting the set number of ceramic tiles, the clamping and ascending mechanism corresponds to the position of the turning mechanism before the turning, the turning mechanism is used for turning tipsily leaned ceramic tiles into the horizontal state and placing the ceramic tiles onto a conveying belt, the conveying mechanism comprises a chain plate conveying belt and is used for realizing the moving of a load bearing tile frame, the ceramic tiles are continuously taken away, meanwhile, the ceramic tiles can be continuously supplemented to reach the tile stacking position, and an empty tile frame pushing mechanism is arranged in the tile stacking position and is used for fast moving way an emptied tile frame for preventing a full-tile tile frame behind from being blocked. Compared with the prior art, the ceramic tile stacking machine provided by the invention is applicable to the tile stacking of the ceramic tiles stacked in a longitudinal inclined stacking mode, and has the characteristics of high tile stacking efficiency and high tile stacking stability.
