Description

Technical Field

[0001] This utility model relates to the field of crushing and recycling waste square bottom valve bags, and in particular to a crushing and recycling device for waste square bottom valve bags. Background Technology

[0002] Square-bottom valve bags, a common industrial packaging material, are widely used in the packaging of powdery and granular materials in industries such as cement, chemicals, and grain. Their structure is typically made of multi-layered composite plastics or plastic and paper composites, providing high strength and moisture resistance. However, after fulfilling their packaging purpose, these bags become industrial solid waste that is difficult to biodegrade naturally. Because square-bottom valve bags often retain their three-dimensional square bottom structure after unloading, and the bag body often becomes fluffy and wrinkled due to residual material, this presents specific challenges in recycling. Traditional crushing equipment, such as ordinary single-shaft or double-shaft shredders, easily encounters feeding difficulties, low crushing efficiency, or even equipment jamming when processing these fluffy and resilient bags due to the bag's wrinkles and entanglement. Furthermore, large particles that may not be completely emptied from the bag, if not effectively separated, will directly affect the purity of the crushed plastic particles or flakes, reducing the economic value of the recycled material.

[0003] Therefore, it is necessary to propose a crushing and recycling device for waste square bottom valve bags to solve the above problems. Utility Model Content
