Description

Technical Field

[0001] This invention 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. Summary of the Invention

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

The feeding unit is used for spreading and conveying the re-dried leaves, the material storage unit is used for constant temperature preservation of the leaves, and the discharging unit is used for outputting the stored re-dried leaves for inspection.

[0010] In at least one possible implementation, the feeding unit comprises a vibrating spreading belt and a belt conveyor belt;

[0011] The vibrating spreading belt is located in front of the belt conveyor belt and is used for spreading the leaves;

[0012] The belt conveyor belt is used for feeding the leaves into the material storage unit.

[0016] In at least one possible implementation, the material storage unit is further configured with a second timer, and the second timer is used for outputting the leaf storage time in association with the prompting unit.

[0017] In at least one possible implementation, the discharging unit adopts a belt conveyor device connected with a discharging port of the material storage unit.
