Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cigarette processing, more particularly to a multi-layer tobacco material sampling device for a closed space. BACKGROUND

[0002] At present, the on-site technical transformation of the cigarette manufacturing workshop of our factory has been completed, and the number and layout of the silos have changed greatly. The finished cigarette tobacco storage process has changed from silo storage to box storage. Process inspectors need to sample the tobacco materials in the closed spaces such as the tobacco storage box and the silo to detect process indicators such as the whole tobacco structure, moisture, and filling value of the materials. However, in the actual operation process, there is no special material collection equipment. Generally, manual sampling is used, and the sampling results are affected by manual operation methods. Moreover, it is difficult to collect materials at different depths.

[0003] During the material sampling process, the following problems exist: (1) Direct sampling by hand can affect the tobacco structure and may cause damage to the tobacco structure. Different sampling methods of different personnel can affect the accuracy of the sampling data. (2) The weight of the tobacco material during sampling can be too much or too little. Too much causes waste, and too little requires repeated sampling, leading to uneven sampling and biased data. (3) Sampling can only be performed on the surface of the silo, and it is difficult to collect deep-layer materials. It is difficult to detect and compare materials at different depths.

[0004] At present, there are multi-layer sampling devices that set up a slender volume and a tapered tip to be reused. However, such a design has certain defects. First, the slender volume leads to a small sampling amount, which affects the accuracy of the sampling data. Second, the tapered tip can damage the tobacco structure when repeatedly inserted, which affects the quality of the subsequent cigarette rolls.
