Description

Technical Field

[0001] This utility model relates to the field of plastic recycling technology, specifically to a plastic recycling conveying device with a dustproof structure. Background Technology

[0002] Plastic recycling is a key measure to address plastic pollution and achieve resource recycling, and it has significant environmental, economic and social implications. Plastics degrade slowly in the natural environment, and large amounts of waste plastic end up in landfills, not only occupying valuable land resources but also potentially polluting soil and groundwater. By recycling plastics, the amount of plastic entering landfills can be significantly reduced, thus mitigating the potential harm to land and water resources. Every year, a large amount of plastic waste flows into the ocean, causing serious damage to marine ecosystems and threatening the survival of marine life. Recycling plastics can effectively prevent these plastics from entering the ocean, protecting marine biodiversity and the balance of marine ecosystems.

[0003] Existing plastic recycling conveying devices typically use conveyor belts to transport shredded plastic to crushing equipment for further processing. During the conveying process, the varying shapes and sizes of waste plastics can easily cause blockages on the conveying device, resulting in low conveying efficiency and damage to the drive equipment. Furthermore, the presence of a large amount of dust and small plastic fragments on the surface of waste plastics pollutes the working environment and is detrimental to the health of workers. Therefore, we propose a plastic recycling conveying device with a dustproof structure. Utility Model Content

[0004] The purpose of this utility model is to provide a plastic recycling conveying device with a dustproof structure, in order to solve the problems mentioned in the background art. Existing plastic recycling conveying devices usually use a conveyor belt mechanism to transport the crushed plastic to the crushing equipment for crushing. During the conveying process, due to the different shapes and sizes of waste plastics, they are prone to blockage on the conveying device, resulting in low conveying efficiency and damage to the drive equipment. At the same time, the large amount of dust and small plastic fragments on the surface of waste plastics pollute the working environment and are detrimental to the health of workers.

At the same time, the duct fan 440 is started to draw residual dust and small plastic fragments on the plastic products into the first collection chamber 430. After the small plastic fragments are filtered by the filter cover 431, the dust continues to be introduced into the second collection chamber 460 through the second pipe 450 and filtered by the metal mesh filter element 470. Finally, clean air is discharged. When the staff finds that the conveyor belt 210 is blocked, the second DC motor 370 and the electric push rod 390 are started. The electric push rod 390 drives the connecting plate 300 to a position above the conveyor belt 210 according to the set stroke. The second DC motor 370 drives the second connecting roller 350 and the lever 360 to move the blocked plastic products until the conveying is smooth. Then the electric push rod 390 is started to return to its original position, and the use is completed.
