Existing cutting devices cannot effectively collect the debris generated during cutting. At the same time, due to the characteristics of polyurethane foam, some debris will adhere to the saw blade during the cutting process. The existing cleaning method is manual cleaning, which is inefficient and has a certain risk factor. Therefore, those skilled in the art provide a polyurethane foam trimming and cutting device to solve the problems mentioned in the background art. Utility Model Content
