Technical Field

[0001] The utility model relates to the field of dryer fabric cleaning, in particular to an on-line high-pressure cleaning device for the dryer fabric of a corrugating paper machine. Background Art

[0002] In the production process of corrugated cardboard, the dryer fabric conveyor belt, as one of the important components, is responsible for carrying and transporting the corrugated cardboard that has not been completely dried. Since residues such as paper scraps and glue will be left during the transportation of the cardboard, these residues will gradually accumulate on the dryer fabric, which not only affects the drying quality of the cardboard but also reduces the service life of the dryer fabric. Regularly cleaning the dryer fabric is one of the key links to ensure the normal operation of the production line.

[0003] The traditional dryer fabric cleaning method is usually manual cleaning after shutdown or simple brushing. This method is not only time-consuming and laborious but also inefficient, and it is difficult to completely remove stubborn stains. In order to improve the cleaning efficiency and reduce the shutdown time, this solution automatically completes the cleaning of the dryer fabric by means of high-pressure spraying and air jetting, greatly improving the production efficiency and the cleaning degree of the dryer fabric.
