[0002] Household waste refers to solid waste generated in daily life or in activities that provide services for daily life, as well as solid waste that is considered household waste according to laws and administrative regulations. In household waste treatment, "soft plastics" usually refers to lightweight, thin, and flexible plastic waste, mainly including plastic bags (shopping bags, garbage bags), plastic films (food packaging films, cling film), plastic tubes (toothpaste tubes, facial cleanser tubes), plastic woven bags, and foam plastic fragments. These plastics are difficult to separate directly from household waste due to their large volume, low density, and tendency to tangle, and are often mixed with oil, kitchen waste, etc., making them a key challenge affecting resource recycling efficiency. Soft plastic extraction devices are specialized equipment systems designed to efficiently separate and purify soft plastics from mixed household waste. Their core objective is to separate soft plastics from other waste (such as kitchen waste, paper, glass, metal, and rigid plastics) through physical, mechanical, or intelligent technologies, providing pure raw materials for subsequent recycling (such as granulation, incineration power generation, and pyrolysis for oil production).

[0003] Existing soft plastic extraction devices typically use sieves to screen and extract soft plastics. However, when the soft plastics stick to the sieves, they become clogged, affecting the screening efficiency and hindering subsequent extraction of the soft plastics.

[0004] Therefore, we propose a flexible plastic extraction device to solve the above problems. Utility Model Content
