[0003] A granulator is a commonly used piece of equipment in industrial production. It can mix, stir, compress, and granulate various raw materials to produce granules of various shapes and sizes. For example, twin-screw granulators are commonly used for filling, blending, modifying, adding, chlorinating, processing polypropylene and superabsorbent resins in rubber, plastics, and engineering resins. This equipment is now widely used. To effectively reuse resources, materials such as waste bottle caps are often used for secondary granulation. These materials require the waste to be cut into sheet-like caps before being fed into the granulator. However, since these materials are usually centrally recycled, although pre-cleaning is performed during recycling, impurities such as dust may still be mixed in. If these impurities are not treated, they will affect the granulation quality. Therefore, a feeding device has been proposed to solve this problem. Utility Model Content
