The utility model relates to a paste the tag paper automatic labeling machine who attachs at the label. Automatic labeling machine includes that frame, feeding mechanism, push mechanism, positioning mechanism, transport mechanism and labeling machine construct. This automatic labeling machine can be voluntarily stick the paper of labelling at the label, adopts the feeding mechanism who contains planetary gear set, can put many piles of label subsides, and feeding drive device pastes gyration to pay -off station with the label when carrying out the pay -off, and push mechanism sees the label subsides off, and positioning mechanism fixes a position centre gripping work, and transport mechanism sees the label subsides to be constructed by labeling machine off and accomplishes the tag paper and paste. This automatic labeling machine can paste the tag paper to many piles the label subsides of piling up, adopts electric integrated design, compact structure, uses portably, is favorable to improving the paste efficiency of tag paper.
