Rolling-type labelling mechanism of automatic print labelling machine

The invention discloses a rolling-type labelling mechanism of an automatic print labelling machine. The rolling-type labelling mechanism comprises a label conveying mechanism, wherein the label conveying mechanism is used for conveying labels to a roller, and is connected onto a cylinder exerting downward pressing acting force on the label conveying mechanism; the fixed end of the cylinder is rotationally connected with a cylinder fixing seat; the roller used for rolling on an object to be labelled is arranged at the front end in the conveying direction of the label conveying mechanism; the labels are conveyed onto the roller through the label conveying mechanism. The rolling-type labelling mechanism can be used for labeling on not only a single plane, but also an arc surface or various surfaces with height distances therebetween.
