The invention discloses an aluminum pipe color printing automatic charging device. The aluminum pipe color printing automatic charging device comprises a base. A first supporting plate and a second supporting plate are arranged at the upper end of the base. A first transverse plate is fixedly connected with the upper end of the first supporting plate. A second transverse plate is fixedly connectedwith the upper end of the second supporting plate. A material container is fixedly connected with the bottom of the first transverse plate. A discharging port is formed in the side wall of the bottomof the material container in a penetrating mode. A holding plate is arranged on the side wall of the first supporting plate in a penetrating mode. A moving groove is formed in the side wall of the holding plate in a penetrating mode. A limiting sliding plate is fixedly connected with the bottom of the moving groove. A movable plate is arranged at the upper end of the limiting sliding plate. A first sliding groove is formed in the side wall of the bottom of the movable plate. The limiting sliding plate is slidably connected with the first sliding groove. The aluminum pipe color printing automatic charging device is reasonable in structure design and easy to operate, automatic charging can be conducted, and the stability of aluminum pipe bodies in the color printing process can be improved.
