[0002] Recycled plastics refer to plastics obtained by processing waste plastics through physical or chemical methods. This process includes steps such as pretreatment, melt granulation, and modification, aiming to transform waste plastics into reusable materials. Recycled plastics have good processing properties and are easy to mold, cut, and weld, so they can be used to manufacture various plastic products, such as water pipes, agricultural machinery, packaging bags, and toys. Recycled plastics have a wide range of applications, including textiles, food and beverage packaging, and home building materials, and are one of the ways to achieve sustainable development of plastics.
[0003] Currently, recycled plastics often have dust and dirt adhering to their surface, which is not conducive to subsequent melting, granulation, and modification of recycled plastics, and is also difficult to remove. Therefore, we propose an environmentally friendly raw material pretreatment equipment for plastic recycling. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This utility model, by setting up a processing box, a crushing box, crushing rollers, a conveyor belt, branch pipes, cleaning nozzles, a cold air hood, and a hot air hood, achieves the ability to crush and clean recycled plastics to remove impurities such as dirt and dust adhering to the plastic surface, and to dry the moisture on the surface of the cleaned plastics, so as to facilitate the subsequent processing of recycled plastics such as melting, granulation, and modification. The recycled plastics are added into the crushing box from the feed hopper, crushed by the crushing rollers, and the crushed plastics fall onto the conveyor belt and are conveyed by the conveyor belt. The cleaning water sprayed from the cleaning nozzles cleans the plastics on the conveyor belt to remove dust, dirt, and other impurities adhering to the surface of the plastics. When the cleaned plastics pass under the cold air hood, the surface moisture is blown off. When the plastics pass under the hot air hood, the residual moisture on the surface of the plastics is dried by the hot air. Then the plastics are conveyed out of the processing box by the conveyor belt.
[0013] 2. By setting the first guide roller and the second guide roller, this utility model guides the conveyor chain, allowing it to pass through the inside of the processing box to transport the crushed recycled plastic. Attached Figure Description
