梳棉机后固定盖板隔距对结杂的影响

为探讨后固定盖板隔距对棉结杂质的影响,用AFIS单纤维测试仪对不同道夫、刺辊速度和后固定盖板隔距所加工生条的棉结杂质情况做了检测,结果显示,当梳棉机产量较低时,采用0.50 mm后固定盖板隔距对棉结杂质去除比较有利;当梳棉机产量较高时,杂质去除以原机状态和0.75 mm隔距方案为最佳,小隔距的0.25 mm方案最差.当刺辊速度在800 r/min时,加装后固定盖板几个方案的棉结去除均不及不加固定盖板的原机状态;当刺辊速度在1000 r/min～1200 r/min时,加装后固定盖板的1.00 mm、0.75 mm隔距方案总体上有利于棉结去除(均比原机状态好).综合棉结杂质去除,以后固定盖板隔距取0.75 mm较佳.从杂质平均尺寸变化来看,加装后固定盖板可能使杂质梳碎的可能性增加.

Influences of Carding Machine Back Stationary Flat Gauge on Neps and Impurities

To discuss the influence of back stationary flat gauge on neps and impurities, neps and impurities of slivers of different doffer speed, licker-in speed and back stationary flat gauge were tested by AFIS single fiber tester. The result shows that 0.5 mm back stationary flat gauge is feasible to eliminate neps and impurities, when carding machine output is lower, without back stationary flat 075 mm gauge is suitable when the output is higher, 0.25 mm gauge has the worst function to wipe off neps and impurities. When linker-in speed is 800 r/min, eliminate neps and impurities function of without back stationary flat is worse than that of not adding back stationary flat. When licker-in speed is 1000 r/min - 1200 r/min, adding stationary flat with 1.00 nun and 0.75 mm gauge is feasible for eliminating neps, it is better than raw machine. Combing with eliminating effect of neps and impurities, 0.75 mm gauge is better. From impurity size, adding back stationary flat increase possibility of impurities becomes pieces.
