Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical coating equipment, in particular to an automatic roller cleaning device for a material taking roller of a roller coating machine. Background Art

[0002] In the production of continuous electrogalvanizing and color coating units, the roller coater located in the coating section applies different reagents or coatings on the upper and lower surfaces of the strip. The most important mechanism of the roller coater is the coating mechanism. The coating mechanism is also called the coating head, which is composed of a feed roller, a coating roller and a coating tray. This form of structure is usually called a two-roller type. The function of the feed roller is to pick up the coating from the coating tray and transfer the coating to the coating roller, which then applies the reagent or coating to the surface of the coil. Since there may be impurities in the coating in the coating tray, or during the entire coating process, the coating liquid is exposed to the outside, and impurities in the surrounding environment can easily fall into the coating liquid, it is inevitable that impurities will be mixed in the coating. If the impurities in the coating liquid adhere to the coating roller along with the feed roller, it will affect the coating quality of the strip surface. If the strip runs at too high a speed, some sharp and hard impurities may even scratch the strip surface. During normal production, if there are impurities on the coating roller and the feed roller, they are generally wiped manually. Manual wiping is inefficient and poses a great safety hazard. If quality problems occur, the only option is to replace the roller. The coating roller can be replaced quickly, which has little impact on the production line, while the take-up roller can be replaced slowly, which has a greater impact on the production line. Therefore, it is very important to study an automatic roller cleaning device for the take-up roller of a roller coater and improve the cleaning method of the take-up roller. Summary of the invention
