Description

Tobacco lamina taking production device

Technical Field

The invention belongs to the technical field of tobacco leaf production, and particularly relates to a tobacco leaf taking and producing device.

Background

The leaf redrying is a tobacco sheet processing technology commonly used in the tobacco industry at present, and the raw material tobacco sheets meeting the production requirements of cigarette enterprises are formed by threshing and drying the primary-cured tobacco leaves. The redried strip tobacco is generally packaged by a corrugated case, and the national standard specifies two standard sizes of 1136mm multiplied by 720mm multiplied by 725mm and 1115mm multiplied by 690mm multiplied by 725 mm. After the redried strip tobacco is put into the carton, the strip tobacco is compacted in a mechanical extrusion mode, the volume of the strip tobacco is greatly reduced, and the transportation and the storage of the strip tobacco are facilitated. The weight of the tobacco flakes is generally 200 kg/box (even 400 kg/box), and the tobacco flakes need to be cut and loosened in use before further processing can be achieved. The processing mode has the following disadvantages that firstly, 200kg of tobacco sheets are filled in a space less than 0.5 cubic meter, and the uniformity of the packing density of the tobacco leaves is difficult to ensure; secondly, before the tobacco flakes are produced and used, the tobacco flakes need to be pre-loosened by slicing, so that the tobacco flakes are crushed. These cases are accompanied by the following problems: firstly, the effect of storing the tobacco flakes is influenced, and the unstable packing density easily causes part of tobacco leaves to go bad by pressing oil; secondly, the stability of cigarette processing is easily influenced during production and processing; thirdly, the higher weight makes the smoking inspection of the tobacco flakes extremely difficult, and the quality of the tobacco flakes is difficult to accurately grasp.

In order to solve the problems, the cellular packing box is used for storing the tobacco leaves, the packing box is divided into a plurality of areas, the tobacco leaves in each area have the same quality, the tobacco leaf slitting or inserting and dividing process can be omitted in the tobacco leaf shredding production, the tobacco leaf shredding is reduced, however, due to the limitation of the partition plates, the tobacco leaves are not easy to take out in the tobacco leaf shredding production, and the cellular packing box cannot be connected with the existing tobacco leaf shredding production line when the tobacco leaves are taken.
