Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a stripping plate structure with an airflow baffle of a needle loom. Background Art

[0002] The needle punching machine is a blanket-making device that compacts and needles a refractory fiber blanket of a certain thickness to weave a refractory fiber blanket. The fiber web is repeatedly punctured by a needle with a triangular or other shaped cross-section and barbed hooks on the edges. The fiber web from the cross-web or air-web machine is very fluffy when fed into the needle punching machine. It only generates a certain strength due to the bonding force between the fibers, but the strength is very poor. When multiple needles penetrate the fiber web, the barbed hooks on the needles will drive the fibers on the surface and sub-surface of the fiber web to move from the plane direction of the fiber web to the vertical direction of the fiber web, causing the fibers to shift up and down. The fibers that shift up and down will squeeze the fiber web to a certain extent, causing the fibers in the fiber web to be close together and compressed.
