喷嘴压力和布带位置对滤棒压降稳定性的影响

Effect of Nozzle Pressure and Cloth Belt Position on Pressure Drop Stability of Filter Rod

KDF-2成型机主要有开松机和烟枪两部分构成。开松机将成品丝束开松成蓬松状态,以达到制作特定规格滤嘴棒的要求;开松后的丝束在烟枪内收紧、上胶成型;丝束经喷嘴、烟枪收紧上胶成型过程的稳定性对滤棒的质量有较大影响,在细支棒成型过程中表现尤为明显。通过方差分析对细支滤棒成型过程中喷嘴压力、布带位置进行了研究,发现布带位置对滤棒稳定性影响不明显,对喷嘴压力影响明显。通过回归模型研究了因素和结果之间的关系,找到了喷嘴压力、布带位置最佳工艺参数,对提高细支滤棒质量具有一定参考意义。

KDF-2molding machine was mainly composed of two parts:loosing machine and pipe.The loosing machine loosened the finished silk bundle into a fluffy state,to meet the requirements of making a filter rod of specific specifications.The loose silk bundle was tightened and glued into shape in the pipe.The stability of the filament-bundle through the nozzle and the bong had a great influence on the quality of the filter rod,especially in the process of forming fine sticks.Through analysis of variance,the pressure of the nozzle and the position of the cloth belt during the shaping process of the fine-supported filter rod were studied,and it was found that the position of the cloth belt had no obvious influence on the stability of the filter rod,while the influence of the nozzle pressure was obvious.And the relationship between factors and results was studied by regression model.Finding the optimum processing parameters of the fine-supported rod had certain reference significance for improving the quality of the fine-supported filter rod.
