[0002] In the papermaking industry, the wire blanket of the paper machine plays a vital role, which is responsible for carrying the pulp and helping to form the paper. However, during the production process, the surface of the wire blanket is prone to accumulate various impurities, such as pulp fibers, fillers, chemical additive residues, and dust, etc. These impurities not only affect the quality of the paper, but also accelerate the wear and tear of the wire blanket, shortening its service life. Therefore, regular and efficient cleaning of the paper machine wire blanket is an important measure to ensure the continuous and stable operation of the papermaking production and the quality of the products.
