Abstract
The invention relates to a digitally-positioned mobile printing machine. The digitally-positioned mobile printing machine comprises a guide rail platform and a mobile printing head mounted on the guide rail platform, wherein a synchronous belt is arranged on the lower end face of a guide rail of the guide rail platform; a machine head traveling, driving and positioning mechanism comprises a servo motor driven by a servo driver through a programmable controller; a driving synchronous wheel meshed with the synchronous belt is connected onto the servo motor; an automatic clearance eliminating mechanism is arranged on the mobile printing machine head; and the automatic clearance eliminating mechanism can be used for pressing the synchronous wheel on the synchronous belt in the pressed state of a movable frame of the mobile printing machine head and canceling the pressing action in the lifting state of the movable frame. The positioning of the mobile printing machine head is controlled by parameters set by the programmable controller, and thus high positioning precision is obtained; and in addition, when the width changes, the width can be directly set by a human-machine interface and is changed conveniently, quickly and accurately. According to the automatic clearance eliminating mechanism, the clearance between the driving synchronous wheel and the synchronous belt can be eliminated, so that the relative displacement between the mobile printing machine head and the guide rail platform during printing can be avoided and the printing precision is ensured.
