Comprehensive screening instrument and comprehensive screening method for moisture density and weight distribution characteristics of cigarettes

Abstract

The invention discloses a comprehensive screening instrument for moisture density and weight distribution characteristics of cigarettes. The comprehensive screening instrument comprises a hopper (1), a microwave device (2), a weighing device (3), a sorting device (4) and a case (5) on the outer layer, wherein the hopper (1) is used for accommodating a cigarette sample to be analyzed; the microwave device (2) is positioned at the downstream of the hopper (1) and is used for measuring the moisture and density of the cigarettes; the weighing device (3) is positioned at the downstream of the microwave device (2) and is used for measuring the weight of the cigarette; and the sorting device (4) is positioned at the downstream of the weighing device (3) and is used for sorting the cigarettes with consistent moisture, density and weight together. According to the comprehensive screening instrument for the moisture density and weight distribution characteristics of the cigarettes, detection and screening processes of the cigarettes are not damaged. On the basis of the device, a lossless microwave method is adopted for measuring the moisture and density of the cigarettes, the weighing device (3) is provided with a balance scale and a buffer mechanism and is used for accurately weighing the cigarettes, the sorting device (4) is a drawer type multi-gear cigarette sorting device, and the whole instrument has advantages of being compact in structure, reliable and efficient in operation and the like.

Description

technical field [0001] The invention relates to the technical field of cigarette product quality detection, in particular to a comprehensive sieving instrument for cigarette moisture density and weight distribution characteristics and a comprehensive sieving method. Background technique [0002] In the process of cigarette production, after the shredded tobacco passes through the suction forming system of the crimper, the moisture density and weight distribution of the shredded tobacco bundle of the cigarette changes. At present, in order to improve the quality of cigarette products and customer satisfaction, cigarette manufacturers usually organize a number of smokers to evaluate and score finished cigarettes. Before organizing the evaluation meeting, it is necessary to carry out homogeneity treatment on the cigarettes to ensure the objective consistency of the moisture density and weight of the cigarettes obtained by the evaluation staff, so as to reduce the impact on the ...

Problems solved by technology

[0004] In the existing cigarette sorting device, the cigarettes are weighed from the weighing device and directly fall into the receiving box of the sorting device. Due to the effect of gravity, there will be a problem of shredded tobacco falling during the falling process of the cigarettes , in addition, cigarettes often fail to fall into the corresponding receiving box smoothly during the falling process, requiring manual assistance

The sorted cigarettes are messy and need to be sorted manually, the efficiency is low, and the cigarettes will be damaged during the process of dropping or manual sorting, which leads to the high similarity of moisture density and weight determined in the previous step of detection. After the cigarettes actually fall into the receiving box, the above indicators of the cigarettes are not consistent, which will affect the use of the next test
