Preparation method of detection sample for removing tobacco shreds in sliver materials by cigarette making machine

Abstract

The invention relates to a preparation method of a detection sample for removing tobacco shreds in sliver materials by a cigarette making machine, which comprises the following steps of: a, determining the sample receiving time at a sliver blanking position below a sliver removing barrel of the cigarette making machine: firstly, testing the normal blanking speed V of the sliver removed by the cigarette making machine, and determining the sample receiving time t to be equal to 40 / V (second), according to the sample receiving time V, receiving a sample below a sliver removing barrel of the cigarette making machine through a sample receiving box; b, pouring the sample in the sample receiving box on a smooth plane, uniformly mixing the sample, spreading the sample into a circle with the same thickness by using a tool, and equally dividing the sample into four parts from the center of the circle by using a cross-shaped sample divider; and c, randomly taking two parts, removing the two parts, uniformly mixing the rest two parts again, repeating the step b, quartering the mixture once again, and after quartering, randomly taking one part as a final detection sample. The quartering method is applied to the tobacco shred stem-containing detection sample, so that the sampling workload is small, the efficiency is high, the uniformity of the prepared sample is improved, the detection accuracy is improved, and the representativeness of a sampling inspection result is improved.

Description

technical field [0001] The invention belongs to the technical field of cigarettes, and in particular relates to a method for preparing a sample for detecting the amount of shredded tobacco contained in cut-off sticks removed by a cigarette machine. Background technique [0002] The purpose of the technical index of stem content in shredded cigarettes is to control the puncture defects of cigarettes and ensure that the cigarettes will not go out when they burn. However, this index cannot directly guide the operation of the cigarette making machine. It can only reflect whether the adjustment is in place by using the cigarette machine stem label to remove the shredded tobacco content index. , it is required that shredded tobacco should be contained in the removed stems, and it is also required to control the cost, so that too much shredded tobacco cannot be brought out when removing the stems. At present, this indicator is manually tested by workers, manually picking out the sh...

Problems solved by technology

However, there is currently no method for preparing samples for the detection of cut tobacco content in cut stems, the sampling is random, and the representativeness of the test samples cannot be guaranteed, resulting in large differences in test results, which is not conducive to guiding production
