摘要
生产过程中出现出纸困难、横向厚度不一、压榨断纸、筋道和卷烟纸的罗纹深度过浅等问题时,可能是压榨辊辊面失效所致。压榨辊的辊面磨损、脱胶的原因是过高的线压力、过高的车速、胶辊的表面硬度过低、不合适的中高。为了保护压榨辊的辊面,可以采用双刮刀、摆动式刮刀、纸页剥离装置、光电断纸检测系统、合适的助滤剂和对大压榨辊进行冷却等措施。对陶瓷辊、可控中高辊、胶辊和压榨辊的辊壳材料进行改进,可以延长压榨辊使用的寿命。
During the production process, problems including thedifficulties in arising out of paper, different horizontal thickness,squeezing off paper, tendons road, cigarette paper shallow depth ofrib and other, might be solved by replacing the damaged press roll.Reasons of worn roll surface of press roll and being unglued werecaused by excessive line pressure, high speed roll, too low surfacehardness, inappropriate crown. In order to protect roll surface ofthe press roll, double-scraper, swing-type scraper, paper pagespeeling devices, photoelectric detection system off paper, the ap-propriate filter aids and cooling the large press rolls and so on canbe adopted. The improvement of shell materials such as ceramicroll, crown controlled roll, rubber roll and press roll can be used toextend the life of press rolls.
