Description

Technical Field

[0001] The utility model relates to the field of tobacco strip sampling, in particular to a finished tobacco strip sampling device and a finished tobacco strip sampling tool set. Background Art

[0002] After threshing and re-curing, the finished tobacco strips are cold-packed. Once moisture content is tested and passes, they are released for storage. The finished tobacco strips are stored in the finished product warehouse for two to three years before being shipped to the cigarette factory based on industrial customer needs. During this two- to three-year storage period, warehouse maintenance personnel must constantly monitor tobacco leaf quality, monitoring basic conditions such as moisture content, stack temperature, mold, and insect infestation. Moisture monitoring is particularly crucial. Because tobacco strips are hygroscopic, high ambient temperature and humidity can lead to moisture absorption, mold, and bale burn, resulting in inestimable economic losses. Moisture content in finished tobacco strips is typically determined by hand feel. If moisture content is excessive, samples from that batch are taken for instrumental testing. Samples are evenly distributed across the box number. The top layer of the tobacco strips, approximately 150 to 200 mm thick, is removed. 80 to 120 g of samples are taken at four equal points along the diagonal. These samples are sealed, labeled, and sent for testing. Moisture content is tested using an oven drying method.

[0003] At present, sampling is basically done manually. In order to avoid the mixing of foreign objects, gloves cannot be worn during sampling. It is easy to hurt fingers during sampling, and moisture on hands will also cause deviations in the samples taken, making the samples less representative. The surface cigarette sheets are manually turned over, and then the turned-over cigarette sheets are restored and packaged for storage. This is laborious and time-consuming. In addition, the cigarette sheets that have been turned over for sampling are relatively loose and difficult to restore to their original appearance before unpacking. The cigarette box is not beautiful after repacking. At the same time, it cannot meet the needs of moisture detection and sampling in the box core. The sampling tubes of existing sampling tools (CN109870321A, CN2911643Y) are easy to fall off, the sampling tools are clumsy, not conducive to operation, and have poor flexibility. They also require the use of mechanical equipment and are not easy to operate on site. After the sample is taken out, it is difficult to separate the sample from the sampling tube, which is not simple enough. The sampling tube size is unreasonable, the sampling amount is too large, and waste is caused. In summary, the current main disadvantages are the following two points: 1. Manual sampling, low work efficiency, laborious and time-consuming. Sampling can easily injure fingers, and moisture on hands can also cause deviations in the sample, making it less representative. After sampling, the repacked cigarette box is less aesthetically pleasing. Furthermore, it cannot meet the requirements for moisture testing and sampling in the box core. Second, existing tools suffer from sampling tubes that easily fall off, are of an inappropriate length, and are difficult to operate. They lack flexibility and are not easy to operate on-site. After the sample is removed, it is difficult to separate it from the sampling tube, making it inconvenient.

[0004] In summary, there is an urgent need for a semi-automatic sampling device with a simple structure and easy operation, and the device can conveniently separate the sample from the sampling tube without disassembling the sampling tube. Utility Model Content
