Description

Technical Field

[0001] The utility model relates to the technical field of plastic recycling and processing, in particular to a degradable plastic bag recycling and processing device. Background Art

[0002] Degradable plastic, also known as environmentally degradable plastic, refers to a type of plastic whose products' various properties can meet the requirements of use, and the performance remains unchanged during the shelf life. After use, it can be degraded into environmentally harmless substances under natural environmental conditions. Degradable plastic bags, as harmless plastics, can often be recycled and reused. During recycling, they need to be heated and melted, cooled and cut into granules to facilitate subsequent product production.

[0003] However, most existing recycling and processing devices use water cooling during cooling, which causes a large amount of water waste and water pollution. At the same time, if the thermoplastic pellets are not cooled during cutting, plastic residue will be left on the cutting blade, resulting in poor cutting efficiency. In addition, if the pellets are not guided during cutting, the cut pellets will bounce and fly out. Utility Model Content
