Description

Technical Field

[0001] The utility model relates to the technical field of tobacco processing, in particular to an online automatic sampling and packaging device for a silk thread edge. Background Art

[0002] The physical properties of tobacco, such as tobacco width, tobacco structure and tobacco moisture, are of great concern in the tobacco making process. Through the above-mentioned physical properties of tobacco, the quality of tobacco making can be evaluated and the adjustment of tobacco making process parameters can be guided. The accurate acquisition of tobacco physical properties requires that tobacco samples be comprehensive and that tobacco breakage be avoided as much as possible during the storage and transportation of samples. Therefore, standardized sampling of tobacco is an important step in the tobacco processing process.

[0003] At present, tobacco line sampling can be divided into two methods: manual sampling and vacuum extraction sampling. Among them, during manual sampling, in order to ensure personnel safety and convenience of transportation, samplers use metal trays to scoop tobacco samples directly on the conveyor line, and pack them into bags for inspection. In some cases, samplers will also take samples by grabbing directly on the conveyor line. However, whether it is scooping with a metal tray or grabbing directly, only tobacco at a higher position on the conveyor line can be sampled, and the broken tobacco close to the conveyor line is difficult to obtain. Therefore, the comprehensiveness of manual sampling is poor, and because manual sampling often requires small amounts and multiple times, frequent bagging and transportation will also cause a large amount of tobacco to be broken.

[0004] The vacuum suction sampling method uses negative pressure to absorb tobacco samples. Since the samples are mostly from the surface of tobacco, the comprehensiveness of the samples is also poor. In addition, the entire suction process cannot avoid the tobacco from being broken into pieces, and the high-speed flow of air will also cause the loss of moisture in the tobacco.

[0005] Therefore, there is an urgent need to propose a standard sampling method that can comprehensively cover tobacco samples and ensure that the physical properties of tobacco remain unchanged. Utility Model Content
