Rotary collecting device for recycling plastic film residues

The utility model relates to the technical field of residual film recovery, in particular to a rotary collecting device for residual film recovery. The film picking device comprises a film picking wheel, embedded cylinders are evenly embedded in the outer portion of the film picking wheel, contraction springs are placed in the embedded cylinders, end limiting columns are arranged on the inner sides of the ends, located outside the film picking wheel, of the embedded cylinders, film picking tooth nails with the contraction function are arranged in the middles of the end limiting columns in a penetrating mode, and cavities are formed in the film picking tooth nails. And inner insertion rods are inserted into cavities of the film picking tooth nails. Through the arrangement, compared with the prior art, the film picking tooth nails have the contraction function, once the film picking tooth nails touch a hard object, the film picking tooth nails can contract to a certain degree and cannot make hard contact with t
