The invention discloses a waste smashing and recovering device for plastic products. The waste smashing and recovering device comprises a recovering tank. A storage box is slidably connected to the bottom end in the recovering tank, and an electric hearting pipe is inlaid in one side in the recovering tank. A feeding shell is welded to the upper end of one side of the recovering tank, and a conveyor belt body is fixedly mounted at the bottom end in the feeding shell through a rolling bearing. A smashing shell is welded to the outer end of the top of the feeding shell, and two sets of mutually-matched smashing rolls are fixedly mounted in the smashing shell through rolling bearings. A water tank is fixedly mounted at the top of the feeding shell, and an exhaust fan is mounted at the top ofthe recovering tank in an inlaid mode. An air pipe is fixedly mounted at the top end of the exhaust fan. The end of the air pipe is movably connected with a filtering device. The waste smashing and recovering device is simple and reasonable in structural design, convenient to operate and good in smashing effect on waste, recycling of the plastic products is convenient, waste gas can be treated, safety and stability are achieved, the application range is wide, and promoting and popularizing are facilitated.
