Description

Technical Field

[0001] The utility model belongs to the technical field of waste plastic recycling, and in particular relates to a waste plastic recycling compression device. Background Art

[0002] As people's environmental awareness continues to increase, waste plastics have been well recycled, especially various plastic bottles. In the process of transporting waste plastics, some larger plastic bottles take up more space. If they are directly piled on the transport vehicle, the quality of waste plastics effectively transported in a single time will be reduced, which greatly affects the transportation efficiency of waste plastics. Therefore, a recycling compression device is needed to reduce and compress the volume. When the cap of the waste plastic bottle is tightly closed, there may still be residual liquid or gas in the waste plastic bottle. The waste plastic bottle with a sealed cap cannot be completely compressed by using a pressing plate, which affects the effect of recycling compression. Utility Model Content
