Waste plastic crushing and recycling device and method

Abstract

The invention discloses a waste plastic crushing and recycling device and a method. The device comprises a crushing box, wherein a first-stage crushing cavity and a second-stage crushing cavity are formed in the crushing box, a first feeding opening is formed in one side of the first-stage crushing cavity, a second feeding opening is formed in one side of the second-stage crushing cavity, a discharging opening is formed in the side, close to the second feeding opening, of the bottom of the second-stage crushing cavity, and four supporting legs are connected to the bottom of the crushing box. According to the device, when a conveying assembly conveys waste plastics and large-size materials are conveyed on a conveying belt, small-size materials can fall on a sieve plate from material leakage gaps, excessive dust raising caused by excessive smashing of the small-size materials is prevented, a transmission part drives the conveying belt to work and meanwhile drives a shaking part to work, the sieve plate is shaken, accumulation and jam of the materials are prevented, the materials on the sieve plate enter the second-stage crushing cavity to be crushed, part of the materials fall into a recycling box from meshes of the sieve plate to be recycled, and the materials with smaller sizes are prevented from being excessively crushed.

Description

technical field [0001] The invention relates to the technical field of waste plastic recycling, in particular to a waste plastic crushing and recycling device and method. Background technique [0002] Plastic recycling refers to the use of certain recycling processes to recycle and reuse waste plastics to achieve the purpose of turning waste into treasure. Waste plastics include various types of plastics. Before recycling, they need to be crushed uniformly to facilitate subsequent recycling. [0003] The existing patent notification number CN 108890926 B discloses an environment-friendly plastic crushing and recycling device, which can crush a large number of relatively large plastics through a crushing mechanism, and perform more detailed crushing on the plastic after the first crushing through two sets of roller mechanisms. broken. [0004] However, when the above-mentioned device is used, after the crushing mechanism crushes the material, the material is likely to remai...

AI Technical Summary

Problems solved by technology

[0004] However, when the above-mentioned device is used, after the crushing mechanism crushes the material, the material is likely to remain on the carrier and cannot enter the roller mechanism for crushing, causing blockage, affecting the crushing and recycling work, and due to the different sizes of the materials, it is easy to cause some materials to be crushed Excessive, affecting subsequent recycling and causing excessive dust during production
