Description

Technical Field

[0001] The utility model relates to the technical field of tobacco production, in particular to a raw material screening device for tobacco processing. Background Art

[0002] Tobacco is a product made from the leaves of the tobacco plant. It is one of the most common smoking products in the world and is widely used to make cigarettes, cigars, pipes and hookahs. The tobacco plant is a perennial plant, and its leaves are the main part of making tobacco products. Tobacco plants usually need to grow in warm and humid climates and require appropriate soil and sunlight. Tobacco is native to South America and is widely cultivated in provinces and regions in the north and south of China. Tobacco likes warm and sunny environments, is not cold-resistant, is relatively heat-resistant, and likes fertile, deep, and well-drained soil. Tobacco mainly relies on division and sowing for reproduction. When processing tobacco, screening devices are needed to screen the tobacco raw materials.

[0003] After searching, it is found that the screening device in the prior art is a raw material screening device for tobacco processing disclosed in publication number CN220004824U. By setting a two-stage screening plate, the aperture of screening plate one is larger than the aperture of screening plate two. Screening plate one screens out small tobacco, tobacco stems and powder to screening plate two. Screening plate one only retains large tobacco after screening and enters the large tobacco collection box. Screening plate two screens out tobacco leaf powder residue and tiny particles and leaves only small tobacco leaves and tobacco stems to enter the stem-shaped tobacco collection box. Then the tobacco powder enters the powder collection box. It can achieve a good multi-stage sorting effect and can sort out three different sizes of tobacco. It has a simple structure and is easy to operate. Collection boxes for large tobacco leaves, small tobacco stems and tobacco powder are specially provided in the inner cavity of the screening box, which is convenient for collection after sorting. The screening plate is detachable, and the aperture size of screening plate one can also be adjusted according to the degree of screening. The aperture size of the sieve hole is adjusted by adjusting the distance between the toothed strip plate one and the toothed strip plate two. It is flexible and applicable.

[0004] The existing tobacco raw material screening device directly uses the screening plate to screen the tobacco raw materials. Since there are many kinds of impurities inside the tobacco raw materials after cutting, the effect of directly using the screening plate to screen is limited, resulting in reduced screening quality of the tobacco raw materials. Therefore, we propose a raw material screening device for tobacco processing. Utility Model Content
