Novel plastic crusher

The utility model relates to the technical field of plastic processing, and discloses a novel plastic crusher which comprises a discharge port, the outer surface of the discharge port is fixedly connected with a first motor, the output end of the first motor is fixedly connected with a rotating rod, and the other end of the rotating rod is rotatably connected with the inner wall of the discharge port. A roller is fixedly connected to the outer surface of the rotating rod, and protective covers are fixedly connected to the two side faces of the roller. Compared with the prior art, the plastic crushing device has the following advantages and effects that a worker puts plastic into the discharging opening, the first motor is driven to drive the roller on the rotating rod to rotate, the plastic is pressed and conveyed, falling of the plastic is buffered, in the crushing process, an arc-shaped baffle protects internal fragments, and the crushing efficiency is improved. And therefore, processed plastic in the crush
