Description
Technical Field
The invention relates to the technical field of cigarette detection, in particular to a cigar hardness tester.
Background
The manually rolled cigars have a long history, and with the improvement of production technology, a series of quantification and data reference need to be carried out on physical parameter indexes of the manually rolled cigars; the hardness is used as an important physical parameter index of the cigarette/filter stick, and in the manually rolled cigar, the hardness also influences the quality of the manually rolled cigar; too low hardness can cause the manual cigar to affect the appearance size, the holding and hand feeling, the ash pile layer in the smoking process and the like in the storage, transportation and consumption processes. Too high a hardness can cause an increase in the resistance of a manual cigar, a decrease in the oxygen content, a decrease in the intensity of combustion, etc. Therefore, there is a need for an apparatus for measuring hardness of a manual cigar to test the hardness of a sample, provide data reference for the manufacturing process of a manual cigar or control the quality of a product.
At present, no instrument or device for detecting the physical parameter indexes of the hardness of the manual cigar exists in the market; the existing cigarette/filter stick cigar hardness tester can not be directly used for detecting the hardness index of the manual cigar; the existing method for detecting the manual cigar mainly depends on sensory experience, and the hardness of the manual cigar is sensed by a human body through pinching and pressing between fingers.
The disadvantages of the conventional techniques are:
the cigarette/filter stick hardness detector can only be used for detecting the hardness index of the cigarette or the filter stick, and is not suitable for detecting the hardness index of the manual cigar.
The perception varies from person to person and the same sample does not give a uniform definition of hardness.
The hardness obtained from human senses does not allow accurate data referencing.
The reasons for the above-mentioned disadvantages are:
the size and shape of the cigarette or the filter stick are uniform, the variation range is small, and the specifications of the common cigarette/filter stick include the length: 40-150 mm, diameter: 5-8 mm. The common manual cigar has the length specification of 60 ~ 210mm, the diameter: 12-25 mm; compared to conventional cigarettes/filter rods. The diameter range of the manual cigar is far larger than that of a cigarette/filter stick; the manual cigar itself is made of tobacco leaves by rolling, and has higher hardness compared with cigarettes/filter sticks.
The fingers between people have different pressure applying areas and different pressure applying forces, so that different feelings are obtained.
Human perception cannot be converted to numeric symbols and unit of measure representations.
Therefore, it is necessary to develop a cigar hardness tester to solve the above problems.
