Problems solved by technology

The measurement of cigarette draw resistance is obtained by converting the pressure difference between the two ends of the measuring stick. The draw resistance of cigarettes is slightly different due to changes in environmental temperature, humidity, atmospheric pressure and other factors; at present, cigarette packing workshops are equipped with a large number of online monitoring instruments , there are differences in the detection values ​​between different instruments, and the maximum value reaches 100Pa, which is not conducive to timely adjustment of the coiler
It is a regular and cumbersome task to unify the detection values ​​between the draw resistance detection instruments and compare the instruments. At present, it only relies on manual regular calibration. Usually, 30 samples of cigarettes taken at the same time period are taken on different instruments. Measurement, according to the average value of the measurement results, to judge the deviation of the detection instrument; but because there are abnormal individuals in the cigarette (the deviation of the draw resistance is large), the error of the comparison result is relatively large

Embodiment Construction

[0009] In order to better illustrate the present invention, an example is given as follows: use acetate tow to make a special school rod, and wrap a layer of wrapping paper outside the special school rod forming paper to stabilize the suction resistance of the special school rod.

[0010] Select special school rod specifications: adjust the filling amount of cellulose acetate tow, roll school rods with different suction resistance and different circumferences, and select special school rods of different specifications according to the need to detect the difference in cigarette circumference and suction resistance; for example, to produce A Brand cigarettes (drawing resistance 1100Pa, length 84mm, circumference 24.3mm) are selected with a special calibration rod comparison online draw resistance tester with a draw resistance of 1100Pa, a length of 84mm, and a circumference of 24.3mm; 24.5mm), a special school rod with a suction resistance of 1250Pa, a length of 84mm and a circum...

Abstract

The invention discloses a method for fast comparing suction resistance between cigarette suction resistance instruments, which belongs to the field of detecting instruments for cigarettes. The method comprises the following steps of: rolling check bars with different suction resistances and different circumferences by adopting acetate fiber tows as special check bars and adjusting the filling volume of the acetate fiber tows; selecting cigarettes of different specifications as special check bars according the difference of the circumference and the suction resistance of the cigarettes which need to be detected; and correcting an online suction resistance tester according to a difference value between marked values and test values of a fixed suction resistance tester and the online suctionresistance tester, so that the suction resistance of all cigarette making machines are controlled to be consistent. Therefore, errors are reduced; the quality of a cigarette product is stabilized; and labor intensity of workers is reduced at the same time. The method has industrial application value and popularization and application prospects.

Description

technical field [0001] The invention relates to a method for quick comparison of draw resistance among cigarette draw resistance instruments, which belongs to the field of cigarette detection instruments. Background technique [0002] Cigarette draw resistance is an important control index of cigarettes. Stable draw resistance can ensure stable smoking style and tar release of cigarettes, achieve stable smoking quality of products, satisfy consumers' smoking tastes, and improve product reputation. The measurement of cigarette draw resistance is obtained by converting the pressure difference between the two ends of the measuring stick. The draw resistance of cigarettes is slightly different due to changes in environmental temperature, humidity, atmospheric pressure and other factors; at present, cigarette packing workshops are equipped with a large number of online monitoring instruments , There are differences in the detection values ​​between different instruments, and the ...
