摘　　要：为解决ZL26C滤棒成型机组生产低单旦醋酸纤维滤棒产生胶孔问题,分别对甘油酯雾化室和丝束开松辊组进行了改进。在雾化室中,拆除对丝束带上甘油酯起梳理作用的支撑板以避免条状飞花堆积,而由导向辊组完成梳理任务;对导流槽进行镜面处理并将导流槽底部设计为拱形,避免形成大颗粒甘油酯;通过实验确定导流槽与丝束带的间距和雾化室出入口间隙分别为0.8 mm和1.0 mm。在开松辊组中,改用硬度为SH85A的胶辊并将开松速比降低至1.22~1.25,辊压降低至140~160 kPa,从而减少飞花形成。以红河卷烟厂生产的“云烟(软如意)”牌卷烟所采用的低单旦醋酸纤维滤棒为对象进行测试,结果表明:ZL26C机组改进后含有胶孔的滤棒数量由496支/d降低至0,且滤棒硬度和吸阻均未发生明显变化。该技术可为提高低单旦醋酸纤维滤棒的质量控制提供支持。To prevent the formation of melting holes in filter rod made of low denier per filament(LDPF)cellulose acetate(CA)tow,the glyceride atomizing chamber and the tow opening rollers in the ZL26C filter rod maker were modified.The support plate that combs the tow band was removed to prevent the accumulated flyings building up,and the combing function was performed by the guide rollers instead.The guide groove was mirror-finished and had a curved bottom to prevent the formation of large glyceride drips.The distance between the guide groove and the tow band and the opening gaps of the inlet and outlet of the atomizing chamber were experimentally determined to be 0.8 and 1.0 mm,respectively.The hardness of the rubber rollers was SH85A in the opening roller pair,and the speed ratio and rolling pressure were reduced to 1.22-1.25 and 140-160 kPa,respectively,to reduce the formation of flyings.The modified ZL26C filter rod maker was tested on the LDPF CA filter rods for“Yunyan(Soft Ruyi)”brand cigarettes in Honghe Cigarette Factory.The results showed that the number of filter rods with melting holes decreased from 496 rod/d to 0,and the hardness and draw resistance of the filter rods did not change significantly.This technology helps to improve the quality control of LDPF CA filter rods.
