A rapid test method for the particle size of incense beads for cigarettes

Abstract

The invention discloses a quick testing method for the particle sizes of aromatic beads for tobacco. The method comprises the steps of image acquisition, namely placing a certain quantity of aromatic beads for tobacco under a monochromatic background randomly, and carrying out vertical exposure on the aromatic beads by a CCD (Charge Coupled Device) camera, a scanner, a vidicon, a digital camera and the like to obtain aromatic bead images; size calibration, namely placing a scale under the same background for vertical exposure of the aromatic beads and exposing under the same parameters; carrying out computer recognition on the aromatic bead images by MATLAB, MATHEMATICA and other mathematical software and other software with the graphic cutting function, and extracting to obtain characteristic parameters of geometry images of the aromatic beads; and performing statistic analysis on data of the diameters of the aromatic beads to obtain the qualified rate of the particle sizes of the aromatic beads. The method can precisely measure the particle sizes of the aromatic beads, and the detecting efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of inspection of the particle size of incense beads for tobacco, in particular to a rapid inspection method for the particle size of incense beads for tobacco. Background technique [0002] Tobacco fragrance beads are granular capsules made of tobacco essence wrapped by wall materials, and buried in the finished cigarette filter rod tow. It is one of the technologies used for cigarette aroma compensation. It has been gradually popularized and used in cigarette processing enterprises. Cigarette quality has a very important impact. For the quality inspection of fragrant beads, there is still a lack of very effective means, especially for the inspection of the particle size of fragrant beads. The current methods include the vernier caliper method and the screen screening method. The vernier caliper method is to manually measure the particle size of the fragrant beads one by one , this method has a large human ...

For the quality inspection of fragrant beads, there is still a lack of very effective means, especially for the inspection of the particle size of fragrant beads. The current methods include the vernier caliper method and the screen screening method. The vernier caliper method is to manually measure the particle size of the fragrant beads one by one , this method has a large human error and is very inefficient; the sieve screening method is to use a sieve with a specific mesh number to sieve a certain number of fragrant beads, and to pass the particle size of the fragrant beads according to the ratio of the number on the sieve and under the sieve. This method is also relatively extensive, and the control precision of screen screening is low and the error is large. At the same time, manual counting and statistics are required, which is time-consuming, labor-intensive, and inefficient.
