Shrinkable adhesive film packaging mechanism

The invention relates to the field of packaging equipment of object packaging films, in particular to a shrinkable adhesive film packaging mechanism. The shrinkable adhesive film packaging mechanism comprises a base plate, wherein a center gear and a driving device for driving the center gear to rotate are arranged in the center position of the base plate; the center gear is connected with at least two sets of rack structures; each set of rack structures comprises two parallel racks; the tail ends of the racks are connected with slide blocks; the slide blocks are connected to the base plate through slide rails; limiting pieces are arranged on the slide blocks, and are provided with arc support pieces; the slide blocks of each set of rack structures are peripherally distributed; and the arc support pieces on each limiting piece are formed to a ring shape. The shrinkable adhesive film packaging mechanism packages products, to be packed through film sealing, with different diameter sizes, so that the production packaging efficiency is greatly improved, the payment of manual packaging costs is reduced, and the technical blank incapable of using one piece of equipment for the products, to be packed through film sealing, with different sizes in the prior art is filled.
