Description

Technical Field

[0001] This utility model belongs to the field of rock wool board cutting technology, specifically relating to a rock wool board cutting and recycling device. Background Technology

[0002] In the production of rock wool boards, the cured rock wool boards need to be cut. During the curing process, because the mesh plate of the curing furnace only has two sides (top and bottom), it cannot restrict the shape of the rock wool boards on the left and right sides. This results in the cured rock wool having flat top and bottom sides, but irregular wavy shapes on the left and right sides. Therefore, the rock wool boards on the left and right sides need to be cut in subsequent processes. Furthermore, due to the wavy shape of the left and right sides and the insufficient density of the rock wool at the edges, the cut dimensions on the left and right sides are relatively large. To recycle this portion of rock wool, it needs to be crushed and transported back through wind-powered pipelines for reuse in the rock wool production process. This process is complex and detrimental to improving production efficiency.

[0003] While basalt, the main raw material for rock wool products, is less hard than steel, finished rock wool fibers commonly contain high-hardness oxides such as SiO2 and AlO3. During the cutting process, these hard particles act like "miniature sandpaper," continuously scraping the surface of the steel blade, causing ongoing damage and shortening its lifespan.
