The invention discloses a multi-row-line automatic telescoping in-mould labeling mechanical hand connected with a cup making machine. The multi-row-line automatic telescoping in-mould labeling mechanical hand comprises a supporting frame, a plurality of groups of mould mechanisms, a row and line sliding telescoping connecting mechanism, a row distance regulating drive source and a line distance regulating drive source, wherein the distance between labeling convex moulds of one or more mould units of each group of mould mechanisms is driven by the row distance regulating drive source to regulate; and distance among the plurality of groups of mould mechanisms is driven by the line distance regulating drive source. The multi-row-line automatic telescoping in-mould labeling mechanical hand has the advantages that: firstly, an existing cup making machine and an original mould are utilized to upgrade and update old equipment; secondly, distance between rows and lines of the labeling convex moulds is telescopic, so that flexibility is high; thirdly, in-mould labeling of a thermal forming container is not limited by various shapes; and fourthly, the multi-row-line automatic telescoping in-mould labeling mechanical hand disclosed by the invention is simple in structure, is strong in adaptation, is simple and convenient to operate, and automatically stretches out and draws back for enabling a cup-making mould to increase row-line cavity number, so that working efficiency is improved.
