Double-layer blocking plastic bottle

The invention relates to the technical field of plastic bottle recycling, and discloses a double-layer blocking plastic bottle. The double-layer blocking plastic bottle comprises a first shell and a second shell, wherein a feeding pipe is fixedly connected to the exterior of the first shell, motors are movably connected to the interior of the first shell, rotating rods are movably connected to theinterior of the first shell, cutter wheels are fixedly connected to the exteriors of the rotating rods, blades are fixedly connected to the exteriors of the rotating rods, and transmission assembliesare movably connected to the exteriors of the rotating rods. Under the interaction of the first shell, the feeding pipe, the motors, the rotating rods, the cutter wheels, the blades and the transmission assemblies, when a plastic bottle starts to be cut, the rotating directions of the rotating rods can be opposite through the two motors, in this way, the two cutter wheels conduct staggered cutting, the cutting of the plas
