Introduction
The needle punching machine is a carpeting equipment for refracting a certain thickness of refractory fiber blanket blank, which is compacted and needled and woven into a refractory fiber blanket. A puncture with a triangular or other shape and with a hook on the edge repeatedly punctures the web. The web that is driven by the cross-web or the air-laid machine is very fluffy when fed into the needle-punching machine. It only has a certain strength due to the cohesion between the fibers and the fibers, but the strength is very poor. When a needle is inserted into the fiber web, the barbs on the needle will drive the fibers on the surface of the web and the subsurface, and move from the plane direction of the web to the vertical direction of the web, causing the fibers to shift up and down, resulting in up and down shifting. The fibers are pressed against the web to compress the fibers in the web.
