Description

Technical Field

[0001] The utility model relates to the technical field of plastic bottle recycling, in particular to a feeding mechanism. Background Art

[0002] The production and use of plastic bottles generates waste, which first needs to be sorted and collected. Common plastic bottles used for drinking water and other beverages are primarily made of PET, and these bottles can be collected and processed separately. The collected plastic bottles are crushed in a crusher, resulting in small plastic fragments. The plastic fragments are then sorted using various methods, including electrostatic separation, screening, magnetic separation, and wind separation, to remove impurities and unwanted components. The crushed plastic fragments are then cleaned to remove any remaining dirt and impurities. The cleaned plastic pellets are then dried in a spin dryer or naturally sun-dried to improve quality for subsequent processing. The cleaned and dried plastic fragments are then fed into a specialized extruder for pelletization. These pellets have two basic uses: blown film and injection molding. Through these processes, the plastic pellets can be processed into a variety of recycled plastic products.
