Cigarette and filter-rod periphery checkout equipment specify that in test zone, sample should not produce eccentric motion, otherwise the speed of laser scanning can affect the precision of diameter measurement.Although " the mensuration part 2 of GB22838.2-2009 cigarette and filter stick physical property: length photoelectric method " does not specify similar requirement, but according to actual measurement principle, in test zone, sample should not produce eccentric motion, otherwise the speed of laser scanning can affect the precision of linear measure longimetry.
This method is fixed in clamping device by sample, and in measuring process, sample does always and at the uniform velocity rotates, and can ensure the stability of each repeatability, gathers all electrical signal datas in continuous rotation process simultaneously.By adjusting eccentric clamper, can change the relative distance of pattern axle center and axis of rotation, gathering length process data amount under a measuring period, research eccentric distance sample size is on the impact of linear measure longimetry.
The step that test sample 9 is being fixed on measurement after in clamp port by the method is as follows:
