Description

Technical Field

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

[0002] Wood-Plastic Composites (WPC) is a new type of composite material that has been booming in recent years at home and abroad. It refers to the use of polyethylene, polypropylene and polyvinyl chloride to replace the usual resin adhesives, mixed with more than 50% of waste plant fibers such as wood powder, rice husks, straw, etc. to form new wood materials, and then produced through plastic processing processes such as extrusion, molding, injection molding, etc., to produce boards or profiles. It is mainly used in building materials, furniture, logistics packaging and other industries. Wood-plastic materials often need to be cut during the processing process, which will form a large amount of scraps. These scraps take a long time to degrade by themselves and can be recycled and made into wood-plastic boards. The existing wood-plastic waste crushing process generally uses high-speed cutting tools for cutting. Due to the high hardness and high structural strength of the wood-plastic material itself, the cutting tool is severely worn and needs to be frequently replaced with a new cutting tool.
