In the printing process of the digital printing machine, sometimes, due to the problem of the material of the printing medium, the left and right deviation occurs, so that the pattern is printed outside the medium. In order to solve the problem that the medium deviates left and right, the existing solution is to pause printing, manually release the air for unwinding the air inflation shaft, adjust the printing medium to a proper position, inflate the air inflation shaft, and continue printing after adjustment. The method needs to stop printing, the tension is changed after the air inflation shaft is deflated, the printing can be continued only by adjusting the tension and the position of a medium before the printing is continued, and the process is complicated and is not easy to operate.

Referring to the drawings, the embodiment of the present application provides a digital printing machine 100, configured to print a medium 200 on a printing platform, where the digital printing machine 100 includes an unwinding device 10, a base 20, and a deviation rectifying assembly 30, where the unwinding device 10 is configured to unwind the medium 200 onto the printing platform, the unwinding device 10 is slidably disposed on the base 20, the deviation rectifying assembly 30 includes a sensing element 31 and a driving element 32, the sensing element 31 is disposed on the printing platform and is configured to monitor a current position of the medium 200; the driving member 32 is disposed on the base 20 and is used for driving the unwinding device 10 to slide relative to the base 20.

It is understood that the medium 200 is wound on the unwinding shaft of the unwinding device 10, and when the digital printing machine 100 starts to operate, the unwinding device 10 continuously unwinds the medium 200 toward the printing platform so that the medium 200 is printed with a pattern on the printing platform.
