Description

Technical Field

[0001] This utility model belongs to the field of online tobacco metering and detection technology, specifically relating to an online tobacco dust metering and collection device. Background Technology

[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] During the production and processing, tobacco materials, especially low-moisture tobacco shreds, are prone to breakage and dust generation when passing through processing equipment due to their poor processing resistance. Material conveying equipment is one of the most frequently used pieces of equipment in tobacco processing production lines. Friction occurs when materials come into contact with the conveying equipment, generating dust and dirt that adheres to the surface of the equipment during transport. As dust accumulates, it can cause it to be scattered or drip onto the workshop floor, hindering production site management and creating significant inconvenience for cleaning and pest control. Furthermore, collecting this dust during material consumption evaluation in cigarette manufacturing is cumbersome, affecting the accuracy of material consumption test data. Offline weighing of this dust is time-consuming and labor-intensive, making it difficult to conduct batch-by-batch consumption evaluations. Additionally, high-moisture materials and materials with added flavorings and fragrances also tend to adhere to the conveying equipment surface, complicating cleaning and causing material waste.

[0004] Currently, there are few reports in the literature on online metering and collection of tobacco dust, and most dust collections do not achieve effective separation of dust from usable materials such as tobacco shreds. Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned shortcomings. Utility Model Content
