Description

Technical Field

[0001] The utility model relates to the field of sorting devices, in particular to a waste polyester whole bottle sorting device. Background Art

[0002] Plastic bottles made of polyethylene terephthalate (PET) are an indispensable part of modern life and are widely used to package beverages, water, oils, detergents and many other liquid products. PET bottles have many advantages, such as excellent transparency, good chemical stability, high impact resistance and excellent oxygen barrier properties, which make them an ideal packaging material. In addition, PET material has high heat resistance and can withstand certain temperatures without reducing performance, making it suitable for hot-filled beverages such as tea and coffee.

[0003] From an environmental perspective, PET's recyclability is another significant advantage. Post-consumer PET bottles can be recycled and reused through physical or chemical methods. Physical recycling involves collecting, washing, crushing and remelting PET bottles into pellets, which can then be used to make new PET bottles or other plastic products, such as fabrics, carpets or automotive parts. Chemical recycling involves breaking down PET into its monomers or other basic chemical components, which can be used to make new PET or other types of plastics.

[0004] However, the main technical challenge in the recycling of waste polyester bottles is that waste PET bottles often carry residual liquids, food or other contaminants. The weight of these residues causes large differences in the weight of PET bottles, thereby increasing the difficulty of sorting and the next step of cleaning. Therefore, manual intervention is required to complete the sorting work. Manual sorting is not only time-consuming and labor-intensive, but also seriously affects the sorting efficiency.
