Description

Technical Field

[0001] The present invention belongs to the technical field of cigarette product quality inspection, and particularly relates to a cigarette diameter detection device. Background Art

[0002] During the production process, since the production speed of the PROTOS cigarette machine is 7000 cigarettes per minute, when the cigarettes are produced, it is necessary to quickly inspect the circumference of the cigarettes. If the inspected circumference does not meet the production quality requirements, the equipment needs to be readjusted. Cigarette manufacturing enterprises implement strict process standards for the circumference of cigarettes. The national standard process standard for the cigarette circumference is the nominal value ±0.1 mm. The conventional inspection method requires the operator to take 30 cigarettes at the sampling point of the equipment sampling wheel and then put the sampled cigarettes into the detection device for detection.

[0003] For example, in a Chinese patent, a rapid cigarette circumference detection device [Authorized Publication No. CN209783471U], includes: a detection plate and a support rod; the detection plate is arranged on the support rod, and the support plate is used to support the detection plate; a plurality of through holes are arranged on the surface of the detection plate; a detection sleeve is nested in each through hole, and a detection hole is arranged in the center of each detection sleeve, and the inner diameters of each detection hole are different; the height of the detection plate is more than 64 mm. When producing cigarettes, the operator only needs to directly insert the cigarettes into the detection holes to quickly determine whether the circumference of the cigarettes meets the production quality requirements. The device has a simple structure and simple and fast operation, saving the detection time of the operator, thus saving the raw material cost, and solving the problem that during the production of cigarettes by the cigarette machine, the operator cannot timely judge the circumference of the cigarettes, which is likely to waste the raw material cost.

[0004] This device requires the operator to put the cigarettes into the detection holes. If the operator's operation speed is too fast, it is difficult to avoid squeezing the cigarettes, which will affect the detection accuracy of the cigarettes. If the operator operates carefully, this will prolong the detection time of the cigarettes. Summary of the Invention
