Description

Technical Field

[0001] This utility model relates to the field of cigarette manufacturing, and in particular to an online sampling auxiliary device for detecting the structure of re-dried and pounded leaves. Background Technology

[0002] Leaf structure indicators are one of the important process quality indicators of tobacco leaf threshing and re-drying lines in the tobacco industry. During the production process, samples of tobacco leaves after threshing or re-drying are taken at regular intervals and the leaf structure is tested in the laboratory.

[0003] Currently, most blade structure testing utilizes multi-layer vibrating screen equipment. This involves separating tobacco leaves of different sizes using screens with varying apertures, followed by weighing and calculation to characterize the blade structure. This method requires timely testing after sampling because changes in temperature over time can alter the blade's morphology, leading to deviations in the blade structure testing data.

[0004] In actual production, a typical leaf re-drying production line is equipped with 1-2 blade structure testing vibrating screens. During busy production periods or when conducting experimental research, a large number of blade structure tests are often required. However, insufficient testing capacity can lead to samples not being tested in a timely manner, resulting in data inaccuracies and an inability to accurately guide production. In other words, according to industry practice, blade structure testing during leaf re-drying must be completed quickly after sampling; otherwise, changes in blade morphology will alter testing characteristics and cause data inaccuracies. However, in actual production, insufficient testing capacity frequently leads to testing delays, affecting the accuracy of blade structure testing data. Utility Model Content

[0005] In view of the above, the present invention aims to provide an online sampling auxiliary device for leaf structure detection by leaf re-baking, so as to solve the problem of leaf structure detection data deviation caused by insufficient detection capability and detection lag.
