[0002] Plastic modification is the process of improving or enhancing the original properties of resins through physical, chemical, mechanical and other means. All plastics can be modified to improve their quality, such as density, hardness, precision, processability, chemical properties, corrosion resistance, aging resistance, wear resistance, flame retardancy, barrier properties and cost. Modified plastics are collectively referred to as "modified plastics". Plastic modification is the most effective way to reduce costs and improve performance. It is widely used in the recycled plastics industry.

[0003] The general production process of modified plastics includes batching, mixing, melt plasticizing and extrusion, cooling, air drying, pelletizing, screening, packaging and other processes. Since the market needs modified plastics of different qualities and functions to meet the needs of different users, in the batching and mixing process, multiple raw materials need to be mixed in a certain proportion before subsequent processing. However, the current mixing is done manually, which cannot be quantitative and automatic, thus affecting production efficiency. Utility Model Content
