Problems solved by technology

[0003] The problem is that the nuclear scanner detects the density of the cigarette through microwave detection, and then calculates the weight of the cigarette indirectly based on the density data and the length of the cigarette, compares the calculated weight with the set weight, and then controls the suction ribbon position, so that the weight is always within the specified value; however, the density of the cigarette is not only related to the filling amount of shredded tobacco, but also related to the circumferential size of the cross section of the cigarette. , the density of the cigarette is affected by the size of the cross-sectional circumference of the cigarette; in the case of the same amount of shredded tobacco, when filled into cigarettes with different diameters, the density of the larger diameter is obviously lower than that of the smaller diameter; when the shredded tobacco conveying device When the position is accurate, if the cigarette circumference control device is inaccurate and the cross-sectional circumference size of the cigarette is too large, the density of the cigarette will be too small. At this time, the scanning device detects that the density of the cigarette is too small, and the control module It will control the shredded tobacco conveying device to increase the filling amount of shredded tobacco until the scanning device detects that the density of the cigarettes reaches the preset range, which will cause the weight of the cigarettes to exceed the standard; If the circumferential size of the cross-section of the cigarette is too small, the density of the cigarette will be too high. At this time, the scanning device detects that the density of the cigarette is too high. If the density of the cigarettes reaches the preset range, this will cause the weight of the cigarettes to not meet the standard

Abstract

The invention discloses a cigarette weight control system and a cigarette weight control method. The cigarette weight control system comprises a density detection device, a cigarette bar leveling device and a weight adjusting device, wherein the weight adjusting device is in communication connection with the density detection device and the cigarette bar leveling device; the density detection device is used for detecting cigarettes and generating a corresponding density measurement value; and the weight adjusting device is used for comparing the density measurement value with a preset densityvalue, and controlling a position of a cut tobacco suction belt of the cigarette bar leveling device according to a comparison result. According to the cigarette weight control system, the density isdirectly detected by the density detection device to control the weight adjusting device, the mode that the density is directly adopted for judgment omits the intermediate link of converting the density into the weight, so that the control sensitivity is improved, the control sensitivity is not affected by the circumference size of the cross section of cigarettes any more, and the regulation and control accuracy rate is greatly improved.

Description

technical field [0001] The invention relates to the technical field of cigarette preparation, in particular to a cigarette weight control system and method. Background technique [0002] The cigarette weight control system is used for real-time measurement of the cigarette weight of the crimping unit. The precise weight control system can improve the utilization efficiency of shredded tobacco, improve the qualified rate of cigarettes, and reduce production costs. At present, the working principle adopted by the cigarette weight control system is: the nuclear scanner detects the weight of the cigarette, feeds back the actual weight signal to the control module, and the control module compares the actual weight with the set weight, and controls the weight according to the comparison result Adjust the leveler to move up and down to control the weight of cigarettes. [0003] The problem is that the nuclear scanner detects the density of the cigarette through microwave detection...
