Abstract
The invention discloses a method for detecting defects of aromatic beads in aromatic bead filter sticks. The method comprises five steps as follows: A, selection of the aromatic bead filter sticks; B, acquisition of density distribution of the aromatic bead filter sticks; C, establishment of a density value distribution curve graph of the aromatic bead filter sticks; D, determination of the density peak of the aromatic beads in the aromatic bead filter sticks; E, analysis and determination of the defects. According to the method, the density distribution of the aromatic bead filter sticks is acquired by the aid of a cigarette microwave density tester, then the density distribution curve graph of the aromatic bead filter sticks is established, or aromatic bead peak nature data information of the aromatic bead filter sticks can be calculated with a peak integral method, so that whether the aromatic beads have defects (deficiency or damage) or not is calculated in a statistical manner and judged, accurate judgment on the defects of the aromatic beads in the aromatic bead filter sticks can be realized, the aromatic bead filter sticks cannot be damaged during detection, the detection is non-destructive, and losses of the aromatic bead filter sticks are reduced; besides, data processing and programming can be performed according to a data processing method, automatic batch processing of data is realized, and accordingly, automatic batch detection is realized.
Description
Technical field
The present invention relates to material testing art field, particularly relate to the detection method of fragrant pearl defect in a kind of fragrant pearl filter stick.
Background technology
Along with consumer is more and more stronger to the individual demand of cigarette fragrance, to cigarette blending, protect fragrant technology and have higher requirement, the personalized blending of cigarette and flavouring are protected fragrant problem and are become increasingly conspicuous.By the fragrant pearl of characteristic fragrance built-in in cigarette filter rod or specific function, the individual demand of consumer can be met preferably, also can solve cigarette flavouring preferably, protect fragrant problem.Increasing tobacco enterprise is progressively paid attention to and is increased the R&D intensity to the fragrant pearl filter stick of cigarette both at home and abroad at present, and in the cigarette filter of release, the cigarette product of built-in fragrant pearl also gets more and more.
Fragrant pearl filter stick has the place different from other filter sticks, particularly for the defect situation of fragrant pearl, as the indexs such as breakage, disappearance have strict requirement in its technical characteristic.As the breakage of fruital pearl or disappearance, directly cause smoking property of cigarette Quality of experience problem.At present, the method detecting the These parameters of fragrant pearl filter stick is peelled off the forming paper outside fragrant pearl filter stick, after being torn by the tow of inside, with the naked eye checks these projects.Also have and adopt the method for strong illumination to detect, but this method is invalid to using the fragrant pearl filter stick of dark forming paper, to fragrant pearl, whether breakage detection is also invalid in addition.Therefore, a kind of universal method being applicable to detect fragrant pearl defect in fragrant pearl filter stick is developed significant.
Summary of the invention
For the weak point that prior art exists, the object of the present invention is to provide the detection method of fragrant pearl defect in a kind of fragrant pearl filter stick, whether the method exists the quality problems such as the breakage of fragrant pearl, disappearance for the fragrant pearl filter stick of inspection, improves fragrant pearl product rod quality and provides technical support.
Object of the present invention is achieved through the following technical solutions:
A detection method for fragrant pearl defect in fragrant pearl filter stick, its method is as follows:
The selection of A, fragrant pearl filter stick: choose the fragrant pearl filter stick that length is 120mm, this fragrant pearl filter stick comprises four cigaratte filters, containing a fragrant pearl in each cigaratte filter;
