Description
Technical Field
[0001] The utility model relates to the technical field of cigarette experiment equipment, in particular to an automatic tobacco trimming and feeding system. Background Art
[0002] During cigarette production, smokers' satisfaction and comfort must be considered while ensuring the safety of tobacco products. Studies have shown that the intrinsic qualities of cigarettes, such as the ratio of tobacco product ingredients, tobacco filling density, and filling uniformity, affect the aroma quality and the release of harmful components in the smoke. Therefore, to improve the intrinsic quality of cigarettes, laboratory personnel at tobacco companies will change the ratio of tobacco product ingredients and develop new formula tobacco products. When developing new formula tobacco products, it is necessary to prepare cigarettes from the formulated tobacco with a good ratio and conduct smoking aroma testing. However, since these are experimental test samples, the amount of formulated tobacco is relatively small, making it impossible to prepare formulated cigarettes on the cigarette production line. Currently, in order to more conveniently obtain formulated cigarettes, laboratory personnel use some cigarette fillers on the market to fill empty cigarette cylinders with tobacco.
[0003] Among them, the preparation of formula cigarettes requires weighing tobacco that meets weight requirements. Currently, most laboratory personnel weigh tobacco manually, which is inefficient, has poor accuracy, and is labor-intensive. Although there are automated equipment to load and weigh tobacco, and the tobacco is trimmed, some tobacco is still too long when loading, resulting in uneven loading and a high weighing failure rate, which in turn affects the quality of the filling and affects the preparation and testing of formula cigarettes.
[0004] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the Invention

The scissor head of the pneumatic scissors is located at the front side and extends obliquely downward into the inside of the vibration plate. The base of the pneumatic scissors is located at the rear and upper part of the vibration plate.
[0015] Based on the above, the scissor heads of the pneumatic scissors are set to open and close left and right.
