[0001] The invention relates to the technical field of plastic granulators, in particular to a plastic granulator. Background Art

[0002] Plastic granulation is an important process in plastic processing, which aims to process plastic raw materials or waste plastics into granular products for storage, transportation and further processing. The main types of plastic granulators include single-screw granulators, twin-screw granulators, etc. Each type is suitable for different plastic materials and processing requirements. These machines convert raw materials into uniform particles through process steps such as crushing, melting, extrusion and pelletizing, which are convenient for storage, transportation and further processing. When the existing plastic granulators are conveying materials, the raw materials expand due to the large temperature difference between the inside and outside of the cylinder due to the hopper. When the raw materials are too humid or contain impurities and are mixed into a liquid, the fluidity and melting effect of the materials will be affected, resulting in blockage and reducing the overall granulation effect. Therefore, we propose a plastic granulator to solve the above problems. Summary of the invention
