Description

Technical Field

[0001] The utility model relates to the technical field of plastic recycling, in particular to a shearing device for recycling waste plastics. Background Art

[0002] Waste plastics come from various sources, including discarded packaging materials, plastic containers, housings of electronic devices, etc. Different types of waste plastics may require different types of shearing devices to process in order to meet the requirements of recycling and reuse. A shearing device is a device used to process waste plastic materials. Its main purpose is to shear, crush or compress the waste plastics so that it is easier to carry out subsequent processing and recycling.

[0003] When recycling waste plastics, some of them are hard and difficult to cut, resulting in low cutting efficiency. The waste plastics cannot be cut into pieces quickly and effectively, and the volume of the waste cannot be effectively reduced, which will increase the cost of storage and transportation. When shearing waste plastics, if there is no pushing mechanism, the waste plastics may accumulate or be unevenly distributed in the shearing area, thereby reducing the shearing efficiency. The shearing device may take longer to process the same amount of waste plastics, affecting production efficiency, increasing labor costs, operational complexity and safety issues.
