[0008] Further, the first linear slide mechanism (3) and the second linear slide mechanism (4) are through type screw rod and slide block mechanisms.

[0009] Further, the second linear slide mechanism (4) is arranged above the printing platform (1) by a screw rod and slide block lifting mechanism, and the second linear slide mechanism (4) is lifted in the Z direction by the screw rod and slide block lifting mechanism.

[0010] In the utility model, when the warped carton printing platform is conveyed, first, the paperboard is humidified by the steam spray humidifying device below, at this time, the second linear slide mechanism is raised to a height at which the warped part of the paperboard can pass, then after the paperboard passes below the second linear slide mechanism, the second linear slide mechanism is lowered, and the humidified paperboard is flattened by the spring steel paper pressing piece, since the paperboard has absorbed moisture, the warped part of the paperboard is more easily flattened by the spring steel paper pressing piece, and the upper digital ink jet area will not scratch the print head.
