The invention relates to a waste paper recovery device, in particular to an environment-friendly quantitative waste paper recovery device. The environment-friendly quantitative waste paper recovery device aims to realize the effects that the occupied space of recovered waste paper is small, the demand for labor force is small and manual monitoring is not needed in the whole process. The environment-friendly quantitative waste paper recovery device comprises a supporting rod, a switch, a pressing block, a sliding block, a sliding rail, a base, a first moving rod, a second moving rod, a third spring, a collecting box, a supporting plate, bolts, a compacting box, a first roll wheel, a first pull wire, a first spring, a first pressing plate, an alarm device, a second spring, a second pressing plate, a second roll wheel, a second pull wire, an air cylinder and a third pressing plate, wherein the switch and the sliding rail are sequentially arranged on the base from left to right. The environment-friendly quantitative waste paper recovery device realizes the effects that the occupied space of the recovered waste paper is small, the demand for the labor force is small and manual monitoring is not needed in the whole process.
