Description

Technical Field

[0001] The utility model relates to a high-temperature resistant carbon fiber composite material pull-out clamp suitable for a front group drying cylinder, belonging to the technical field of papermaking equipment. Background Art

[0002] At present, most of the clamps used on the front group of drying cylinders are traditional double-bag scraper clamps. As most of the raw materials used by major paper mills are domestic waste, the humidity of the paper sheets on the front drying cylinders of paper machines is relatively high, and there are many hard impurities such as fibers and adhesives on the surface of the front drying cylinders, which are very difficult to clean. In addition, the paper machine drying cylinders usually reach a higher temperature during operation, which may cause adhesives or stains that are difficult to remove to form on the surface of the drying cylinders.

[0003] After the scraper blade cleans up the paper fibers or adhesives, some of the adhesives and other impurities will adhere to the scraper blade or scraper clamp, and some will enter the airbag chamber of the loading airbag or the lifting airbag, affecting the pressurization or lifting of the clamp tool holder. Another part of the paper fibers or adhesives will enter the finger block where the cleaning scraper is installed. Over time, this will have a great impact on the insertion and removal of the cleaning scraper.

[0004] Therefore, the clamps used in the paper machine should be cleaned frequently to avoid affecting its cleaning function. However, the current double-airbag scraper clamp has the following disadvantages when cleaning: it needs to be disassembled as a whole, which takes a long time, and the original installation position of the scraper clamp may be damaged during cleaning, thereby affecting the cleaning angle of the scraper blade during operation; therefore, the cleaning work of the operator in a high temperature environment is not only inefficient, but also poses a certain threat to the safety of the staff.
