Description

Technical Field

[0001] The utility model relates to the technical field of plastic recycling, in particular to plastic recycling and classification equipment. Background Art

[0002] Iron filings or other metal particles are on the surface or in the middle of plastic particles. The presence of metal particles in recycled plastic particles is the reason why there are iron filings in the raw materials. The main reasons are screw wear and broken moving knives.

[0003] According to a disclosed plastic recycling classification and crushing device (publication number: CN217454558U), the above application is provided with an air blowing assembly, which can blow small plastics and light plastics into the discharge box through a fan, thereby achieving high-efficiency crushing.

[0004] However, in actual use, the above-mentioned equipment uses an air blowing component to classify plastics according to size and weight, but the plastic particles often contain metal impurities inside. When the plastic particles are recycled, the plastic particles and metal impurities cannot be classified, thereby reducing the classification efficiency and thus reducing the effect of plastic recycling. In view of this, we propose a plastic recycling classification device. Utility Model Content

[0025] In the present invention, when in use, plastic particles are put into the shell 1 in batches through the feed port 2. At this time, the plastic particles slide down from the feed plate 3.

After the push switch 19 is applied with force, the electromagnet 11 is powered off and loses its magnetic force, and the metal on its surface falls to the inside of the partition plate 12. In this way, the work of recycling and sorting the plastic particles is completed reciprocatingly, thereby avoiding the recycled plastic particles containing metal impurities, causing inconvenience in their subsequent use, and improving the efficiency of plastic particle recycling and sorting.

[0026] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
