At present, the domestic method of detecting the turning phenomenon of cigarettes is mainly through artificial smoking statistics. This method is more practical, but the statistical cycle is long, time-consuming and labor-intensive, and human factors are greatly affected, so it is difficult to provide a more rigorous and credible test. data, it is impossible to analyze the cause of the U-turn phenomenon
[0004] The Chinese invention patent (CN102937639A) provides a device for detecting cigarette head drop, but the device still has certain deficiencies: 1. The impact force cannot be changed flexibly, so that the test has certain limitations; 2. The impact position is always at For the filter section, due to the change of the length of the cigarette when burning and smoking, the force on the combustion cone is not constant, which has a certain impact on the data analysis; 3. It is difficult to detect the falling position of the combustion cone

[0039] According to the method recorded in the present invention, the cigarette of brand A is tested, and the cut tobacco density distribution curve in the cigarette of cigarette of A brand is as follows: image 3 shown. Brand A cigarettes have a diameter of 5mm, a length of 100mm, and a mouth stick length of 30mm.
[0040] 10 smokers were selected to conduct a controlled test of U-turn rate detection, and each smoker tested 20 cigarettes and recorded U-turns.
[0041] Use the cigarette U-turn detection device to detect the cigarettes, select the scale 3, scale 4, and scale 5 of the lifting scale 1 of the cigarette holder holder for detection, and detect 40 cigarettes on each scale, and record the detection data. The test results are as follows:
[0052] According to the detection method in Experimental Example 1, B brand cigarettes were tested, and the tobacco density distribution curve in B brand cigarettes was as follows: Figure 4 shown. Brand B cigarettes have a diameter of 7.5mm, a length of 84mm, and a mouth rod length of 24mm.
[0062] It can be seen from the test data that the scale 5 is the closest to the U-turn rate detected by the reviewers.
[0063] By analyzing the test data of Experimental Example 1 and Experimental Example 2, the following conclusions are drawn:
[0064] 1. The detection device can simulate the action of ejecting ash during the actual suction process by adjusting the lifting scale 1 of the holder, and the obtai...

Abstract
The invention discloses a device for detecting shedding of a tobacco combustion head and a use method thereof. The device can accurately detect a combustion cone shedding position. The device comprises a support assembly, a cigarette clamping assembly and an impactassembly. The support assembly comprises a base and vertical plates arranged at two sides of the base. The cigarette clamping assembly is arranged at the vertical plates and comprises elevating scales arranged on the vertical plates, two cigarette clamping pieces horizontally arranged on opposite vertical faces of the vertical plates by fixing rotary knobs, and a clamping rubber gasket. The impact assembly is fixed to form an integral body, is arranged on the base in the way of movement along an axial direction of an arc chute and comprises a vertical spring, a hammer pin fixedly connected to the upper end of the spring and having a raised part at the lower part, a vertical guiding member, a variable frequency motor and an eccentric gear in a transmission connection relationship with the variable frequency motor. The hammer pin is in a vertically movable connection relationship with the guiding member.
Description
technical field [0001] The invention relates to the technical field of quality monitoring of cigarette products, in particular to a device for detecting the U-turn of cigarettes and a use method thereof. Background technique [0002] "Cigarette turning around" refers to the phenomenon that the burning cone falls due to the ash action of the cigarette during the smoking process. This phenomenon can lead to cigarette flameout, and has certain potential safety hazards. It is a phenomenon that consumers are more disgusted with. It is one of the physical quality defects of cigarettes that the tobacco industry is actively researching and intending to solve. [0003] The main reasons for the U-turn phenomenon of cigarettes are: 1. The density distribution of shredded tobacco in cigarettes; 2. The compatibility of shredded tobacco structure; 3. The combustion compatibility of cigarette paper. At present, the domestic method of detecting the turning phenomenon of cigarettes is mainl...
