Description

Technical Field

[0001] The invention relates to the technical field of plastic recycling and processing, in particular to a particle processing device for recycling and reproducing waste plastics. Background Art

[0002] Plastic bottles are a common type of plastic waste. Due to their non-degradable nature, the traditional landfill and incineration methods are gradually being abandoned and replaced by reuse, degradation or decomposition processes. The recycling of discarded plastic bottles can not only protect the environment and save energy, but also has good economic benefits.

[0003] A plastic bottle generally consists of a bottle body, a bottle cap and wrapping paper. The wrapping paper is wrapped around the outer surface of the bottle body, and the bottle cap is screwed onto the opening of the bottle body. Due to the functions, processes and cost considerations of each part of the plastic bottle, the materials of these three parts of the plastic bottle are also very different. If they are melted uniformly, different parts of the plastic bottle will melt at different temperatures, which will lead to a waste of resources and will be detrimental to the reuse and recycling of plastics. Therefore, plastic recycling equipment has been derived. The staff will place the plastic bottle into the plastic recycling equipment, separate it from the bottle body by twisting the bottle cap and cutting the packaging bag, and the next plastic bottle can only be separated after the current plastic bottle is separated. This makes the entire plastic recycling process discontinuous, resulting in low plastic recycling efficiency. Summary of the invention
