Problems solved by technology

During the rotation of the sample, it is impossible to determine whether there is an eccentric angle and size. The negative pressure adsorption method is used to clamp the sample, which causes the sample to be adsorbed after completing the normal measurement after each rotation and cannot guarantee the stability of the measurement result. Therefore, the circumference measurement device It is impossible to judge whether the eccentricity angle will affect the final measurement result
At present, there is no good method for judging the degree of influence of the eccentricity angle when measuring the circumference of cigarettes and filter rods.

Embodiment 2

[0031] "GB22838.3-2009 Determination of Physical Properties of Cigarettes and Filter Rods Part 3: Circumferential Laser Method" stipulates that the equipment for rotating the sample with a circular compass is used to keep the sample in the scanning channel of the laser beam or laser scanning around the sample The meridian in the channel is kept perpendicular to the scanning channel. According to the actual measurement principle, the axis of the sample should be parallel to the scanning channel. Since the scanning channel is determined by the position of the laser generator, it is only necessary to ensure the relative angle between the pattern axis and the rotation axis during instrumentation.

[0032] In this method, the sample is fixed in the clamping device, and the sample is always rotated at a constant speed during the measurement process, which can ensure the stability of each repeatability, and at the same time collect all the electrical signal data during the continuous ...

Abstract

The present invention relates to the test field of the circumferences of the cigarette and the filter stick, especially to a validation method of an influence of eccentric angles at the circumference measurement of a cigarette and a filter stick. In the method provided by the invention, a position of a sample is not changed in each measurement process so as to ensure the stability of a measurement result of the sample, the rotations of the samples with eccentric angles in the actual measurement process may be simulated, and the eccentric angles may be controlled and determined so that the laser measurement data is uniformed obtained. According to the invention, the data on different angles may be obtained through regulating the eccentric angles, the average value of all the data may be finally calculated, and the instrument results of the circumferences are obtained on the premise of the unchangeable positions of the samples, the measureable eccentric angles of rotation of the samples and the ensured stability of the measurement results in the repeatability measurement. The validation method of the influence of the eccentric angles at the circumference measurement of the cigarette and the filter stick is reliable in the measurement method and simple in calculation.

Description

technical field [0001] The invention relates to the field of testing the circumference of cigarettes and filter rods, in particular to a method for verifying the influence of eccentricity angles when measuring the circumference of cigarettes and filter rods. Background technique [0002] The current mainstream cigarette and filter rod circumference testing devices in use all adopt the principle of photoelectric detection. Due to the large amount of real-time data of photoelectric detection, the final result obtained by the instrument is the average value of multi-point measurement, and the laser controller can control the amount of process data received per second. During the rotation of the sample, it is impossible to determine whether there is an eccentric angle and size. The negative pressure adsorption method is used to clamp the sample, which causes the sample to be adsorbed after completing the normal measurement after each rotation and cannot guarantee the stability o...
