[0001] The utility model relates to the technical field of papermaking, in particular to a calender guide roller cleaning device. Background Art

[0002] At present, with the continuous development of the papermaking industry, the utilization of raw materials is becoming more and more green and sustainable. Among them, paper tube base paper is mostly made of waste paper tubes and waste paper boxes as raw materials to achieve waste recycling;

[0003] But at the same time, the glue in the waste paper pipes and waste paper boxes will be brought into the pulp system. During the paper sheet forming process, the adhesives will be transferred from the paper sheets to the calender rollers. When the calender rollers are stuck with adhesives, they will stick to the paper sheets, which can easily cause paper breaks during papermaking. The traditional way to keep the calender roller surface clean is to scrape it with a scraper, which increases the number of times the scraper needs to be replaced and the consumption of the scraper. In addition, the replacement of the scraper is not only time-consuming and labor-intensive, but also affects the working efficiency of the calender, which needs to be improved. Utility Model Content
