Background
In the cigarette production process, after the tobacco shreds pass through a cigarette making machine tobacco shred suction forming system, the moisture density weight distribution of the tobacco shred bundles of the cigarettes is changed. At present, in order to improve the quality of cigarette products and customer satisfaction, cigarette manufacturers usually organize a plurality of smokers to evaluate and analyze finished cigarettes. Before the organization evaluation and analysis meeting, the cigarette needs to be subjected to uniformity treatment so as to ensure the objective consistency of the moisture density and weight of the cigarette obtained by the evaluation personnel, thereby reducing the influence on the evaluation and analysis effectiveness. At present, domestic cigarette production enterprises usually examine the moisture density and weight of tobacco shreds singly, and do not have a comprehensive screening platform aiming at the three indexes.
In addition, the weighing device for measuring the cigarette weight in the prior art automatically drops the cigarettes into the scale pan under the gravity before the cigarettes are weighed, and the cigarettes are ejected out of the scale pan and then drop into the sorting device under the action of the gravity after the weighing is finished. If no corresponding measures are taken, the cigarette can be impacted after falling, and the cut tobacco can be loosened and even fall off. This results in that even if the measured cigarette weight is accurate during weighing, the cigarette weight taken into the hand of the evaluation staff is not different after weighing. Therefore, how to maintain the accuracy and stability of nondestructive non-destructive detection of cigarette weight is very critical, and the weighing device in the prior art obviously violates the nondestructive principle. In summary, it is necessary to develop a weighing apparatus with a buffer mechanism.
The cigarette sorting device that has now, a cigarette accomplish from weighing device and weigh, directly fall into sorting device's material receiving box, because the effect of gravity, the problem that the pipe tobacco dropped can appear in the cigarette in the in-process that drops, in addition, the cigarette often appears can not fall into the material receiving box that corresponds smoothly in the in-process that drops, needs artifical supplementary. The cigarette that divides the election is in disorder, needs artifical arrangement, and is inefficient, and still can produce the damage to the cigarette dropping or artifical arrangement in-process, this cigarette that just leads to the moisture density weight similarity height that confirms in the last step of testing process originally, and after really falling into the material receiving box, the above-mentioned index of cigarette is inconsistent, influences experimental use on next step.
The present invention has been made to solve the above problems.
