Problems solved by technology

[0002] Plastic materials have the advantages of light weight, high strength, and good impact resistance, and are widely used in many fields. However, plastic packaging materials have a fatal weakness, that is, their natural degradation time is long, and plastics are not easy to degrade. It will exist for a long time. In order to protect the environment and reduce waste of resources, plastic products are widely recycled and reused.
[0003] The recycling of plastic products needs to be crushed. The existing crushing equipment has a simple structure. Although the secondary crushing is set up, the material is easy to accumulate at the bottom of the box during the fine crushing stage, resulting in uneven crushing and unsatisfactory crushing effect.

Abstract

The invention discloses layered crushing equipment for plastic recovery, relates to the technical field of crushing equipment, and aims to provide layered crushing equipment for plastic recovery, which can prevent materials from being accumulated at the bottom all the time, stir and cut up the materials at different positions and ensure that the materials are uniformly and thoroughly crushed. According to the technical key points, the device comprises a coarse crushing mechanism, a material guide block and a fine crushing mechanism, the material guide block guides materials subjected to primary crushing into a fine crushing cavity, the fine crushing mechanism is used for cutting and crushing the materials in the fine crushing cavity, and the fine crushing mechanism comprises a rotating cylinder. On one hand, the driving motor is arranged between the inner wall and the outer wall of the rotating cylinder, so that the driving motor can rotate along with the rotating cylinder, it is guaranteed that the driving motor stirs and cuts up the materials at different positions, and it is guaranteed that the materials are smashed evenly and thoroughly.
