一种滤棒成型机组出胶量控制方法分析

Analysis of Method for Glue Volume Control in Filter Rod Maker

为了更好地控制滤棒成型机组封口胶(热胶)和内线胶(冷胶)的出胶量,提高滤棒成品品质,减少废品量,介绍了一种在滤棒成型机上实现出胶量控制的方法。该方法直接测量胶泵在各转速n下的质量流量Qm,再根据公式计算出与胶泵固有特性相关的控制参数ε,从而达到准确控制出胶量目的。对于实际操作中涉及的启动过程及启动超量补偿问题进行了论述。该出胶量控制方法实际应用效果表明,涂胶厚宽均匀,胶线无中断无溢出线,快速调整启动阶段的出胶,提高了校准速度和质量,保证了成品滤棒的外观品质和内在质量。

A method for controlling the glue volume applied to filter plug wrap and improve filter rod quality in filter rod making was described.For the purpose of precise control of glue volume,the control parameter ε related to the inherent characteristic of glue pump was calculated based on the mass volumes Qm（g/min） of glue pump determined at different rotating speeds.The volume compensation during startup period in practical operation was discussed.The application results indicated that this method was capable of forming uninterrupted glue line with uniform thickness and width,and regulating glue volume rapidly in startup period,and the quality of finished filter rod was guaranteed.
