Cylindrical surface printing equipment

The invention belongs to the technical field of ink-jet printing, and provides cylindrical surface printing equipment. The cylindrical surface printing equipment comprises a supporting surface, a printing assembly, a first driving assembly and a clamping mechanism, wherein the supporting surface is used for supporting a cylindrical object; the first driving assembly is used for driving the printing assembly to move in the first direction; the clamping mechanism is used for clamping the cylindrical object, and the clamping mechanism and the printing assembly move synchronously in the first direction so as to enable the cylindrical object to roll on the supporting face in the first direction; and a spray head in the printing assembly prints the surface of the cylindrical object in the rolling process of the spray head and the cylindrical object. The surface of the cylindrical object is printed in the rolling process of the spray head in the printing assembly and the cylindrical object, and then the cylindrical
