[0002] Plastic is a high-molecular compound made from monomers through addition polymerization or condensation polymerization. It is commonly known as plastic or resin. It can freely change its composition and shape. It is composed of synthetic resin and fillers, plasticizers, stabilizers, lubricants, colorants and other additives. Plastic is a recyclable daily necessity. Before recycling, the old plastic needs to be crushed, cleaned, extruded and other processes.

[0003] In the related technology, most of the existing plastic recycling and cleaning devices have simple processes, which only use the impact of water flow to wash away the stains and dirt on the surface of the recycled plastic. The impurities attached to the surface of the plastic are not effectively removed, and the cleaning effect is not very ideal, which cannot meet people's current usage needs. For this reason, we propose a cleaning device for plastic recycling.

[0004] The above information disclosed in this Background section is only for understanding the background of the present inventive concept and therefore it may contain information that does not constitute prior art. Utility Model Content
