The invention relates to a packaging label stripping assembly with a floating elastic pressing plate. The packaging label stripping assembly comprises a shell-shaped stripping plate. The front end of the stripping plate is provided with an arc-shaped stripping face. An oscillating rod is installed below the arc-shaped stripping face. The middle portion of the oscillating rod is hinged to the end portion of a supporting rod fixed to the stripping plate. A guide roller is arranged at the upper end of the oscillating rod, the lower end of the oscillating rod abuts against the circumferential face of an eccentric wheel, and the eccentric wheel is driven by a motor. A label pressing assembly is installed on the stripping plate and is in a T shape. The label pressing assembly comprises the pressing plate located above the stripping plate, a fixing rod fixedly connected with the pressing plate and a plurality of parallel pressing rollers installed on the lower surface of the pressing plate. A vertical sliding groove is formed in the fixing rod, the fixing rod is installed on a fixing shaft on the side face of the stripping plate through the vertical sliding groove in an up-and-down sliding manner, and a spring is arranged between the vertical sliding groove and the fixing shaft. The packaging label stripping assembly has the beneficial effects that the label stripping effect is good and the label stripping reliability is high.
