Waste and old plastic pulverizing and grinding device

Abstract

The invention discloses a waste and old plastic pulverizing and grinding device. The device comprises a supporting bottom plate. The top of the supporting bottom plate is fixedly connected to a conveying box. The top of the conveying box is fixedly connected to a pulverizing box through symmetric first supporting legs. The center of the bottom of the pulverizing box is communicated with the top ofthe conveying box. The center of the top of the pulverizing box is communicated with a feeding channel. The top of the feeding channel is communicated with a waste feeding hopper. The two sides of the inner wall of the feeding channel are fixedly connected to symmetric anti-pinch splash-proof devices. The middles of the two sides of the inner wall of the pulverizing box are fixedly connected to symmetric supporting material falling plates. The invention relates to the technical field of plastic processing machinery and equipment. The waste and old plastic pulverizing and grinding device solves the problem that the existing plastic pulverizing device has high energy consumption and poor pulverizing effects and produces secondary pollution, realizes uniform and thorough plastic pulverizing,effectively improves the plastic recovery efficiency and protects the environment.
