[0002] Paper is the most commonly used item in our daily life. Whether reading, reading newspapers, writing or painting, we have to come into contact with paper. In industrial, agricultural and national defense industry production, paper is also indispensable. When making paper, it needs to be cut by a water needle cutting device. Generally, a traditional water needle cutting device is provided with a mesh part. In addition to being used to convey the paper web, the main task of the mesh part is to evenly disperse the fibers and crisscross them to lay a good foundation for the formation of good paper, so that the whole paper page is uniform in quantity, thickness, uniformity, etc., and a water needle is arranged on the side of the mesh part. The water needle penetrates the paper web by spraying a high-pressure water column. As the paper web is conveyed forward, a continuous cutting mark is formed to cut off the edge of the paper web.
