Description

Automatic clamping device of ventilation rate standard rod Technical Field The utility model relates to the technical field of tobacco detection, in particular to an automatic clamping device for a ventilation rate standard rod. Background The ventilation rate of the cigarette is used as an important index for influencing the quality of the cigarette, the size of the ventilation rate is closely related to the generation of cigarette smoke, the taste of the cigarette and the filtration efficiency of a filter tip, and the ventilation rate is directly related to the tar and harm reduction of the cigarette. The cigarette ventilation rate detection equipment used in the tobacco industry is more in brands and models, in order to guarantee the accuracy and consistency of cigarette ventilation rate detection results, the ventilation rate standard rod is generally adopted to calibrate the detection equipment, and therefore the accuracy of the cigarette ventilation rate measurement results is directly affected by the accurate use of the ventilation rate standard rod. The ventilation rate standard rod consists of a rod body made of low-expansion transparent crystal and capillary through holes integrally formed in the rod body, wherein the capillary through holes comprise 10 capillaries along the axial direction and side ventilation holes which are communicated with the capillaries. The capillary tubes are arranged in concentric circles in parallel along the axial direction, and the vent holes are annularly arranged on the periphery of the plug-in end of the rod body. The standard rods with different ventilation rates can be manufactured by adjusting parameters such as the diameter, the number and the like of each capillary through hole. In order to conveniently identify standard rods with different ventilation rates, a printing mark color ring is arranged outside the rod body, and different colors respectively represent different ventilation rates. In the production and manufacturing links and the application links, the ventilation rate standard bars in groups or batches need to be detected or used one by one, more uncertain factors exist in a manual transfer mode, and the ventilation rate standard bars are fragile in the measurement process due to the material and structure specificity of the ventilation rate standard bars. In order to solve the above problems, an ideal technical solution is always sought.
