Abstract

The invention discloses an on-line detecting device and method of tobacco bag density, which comprises the following parts: several testing units, rack, position sensor, data gathering processing system, wherein the detecting unit contains several radiation sources or X-ray sources and several ray detectors; the radiation source and detector are assembled on the rack of two sides of the detected tobacco bag, which corresponds one by one to form several detecting units to test the density of the detected point; the density value is calculated according to several detecting points with maximum deviation a of mean value and maximum density of density at the rate of maximum density-density mean value and density mean value; the maximum deviation b of mean value of maximum density and density minimum value is at the rate of minimum density-density mean value and density mean value; the maximum value of the absolute value of a and b is not more than the given value to judge, which rejects the defective tobacco bag more than the given value by rejecting device. The device and method realizes the on-line non-destroying detection, which possesses high detecting precision and stable and reliable property.

Description

technical field [0001] The invention relates to on-line detection technology, in particular to an on-line detection device and method for cigarette pack density. Background technique [0002] The uniformity of cigarette bale density is one of the important factors affecting the quality of cigarette bale storage and fermentation (alcoholization). At present, each flue-cured tobacco factory adopts a static 9-point sampling method to test the density of the cigarette bale, that is, place the 9-point sampling plate (as shown in Figure 1) on the top of the cigarette bale, press down 15mm, and align the 9 points of the sample plate with a density sampler. Press the samples separately, the depth of the sample is 600mm or 500mm, take out 9 samples respectively, put them into plastic bags of the same quality and label them, and then weigh the samples at each point with a balance, and calculate Density value, average value, maximum value, minimum value, maximum deviation of density m...
