Description

Technical Field

[0002] With the extensive use of plastic products, the hot melting technology of bottle flakes can convert bottle flakes into other plastic products, realizing resource recycling and reducing environmental pollution. The bottle flakes can be heated into a molten body and materials such as plasticizers, antioxidants, lubricants, compatibilizers and masterbatch can be added. Plasticizers can increase the flexibility and plasticity of the hot-melted bottle flakes, antioxidants can prevent the bottle flakes from degrading due to oxidation at high temperatures, when the bottle flakes are mixed with different types of polymers, compatibilizers can improve the compatibility of different polymers, and masterbatch can dye the molten body of the bottle flakes.

[0003] In the prior art, when a single heating mechanism is used for heating, the temperature in the middle is high, so that the bottle flakes cannot be heated evenly. When a single heating mechanism is damaged, the maintenance cost is high, and the bottle flakes are likely to react with water and oxygen in the air during hot melting. Summary of the Invention
