Device and method for automatically selecting tobacco leaves for producing cut tobacco

Abstract

The invention discloses a device and method for automatically selecting tobacco leaves for producing cut tobacco. The device comprises a rolled tobacco leaf removing system, a tobacco stem detecting and removing system, a detecting and removing system for green tobacco leaves and moldy tobacco leaves, an impurity removing system and a tobacco leaf conveyor. Raw tobacco leaves enter the rolled tobacco leaf removing system from an inlet of the rolled tobacco leaf removing system and rolled tobacco leaves are removed; unrolled tobacco leaves are output from the tobacco stem detecting and removing system and the tobacco leaves with the tobacco stems and impurities are detected by the tobacco stem detecting and removing device; the green tobacco leaves and the moldy tobacco leaves with the impurities are separated out by the green tobacco and moldy tobacco detecting and removing system and are removed through a removing mechanism; after the green tobacco leaves and the moldy tobacco leaves are removed, the tobacco leaves enter the impurity removing system, the tobacco leaves are accelerated by the impurity removing system, the impurities are removed, the tobacco leaves obtained after the impurities are removed are conveyed to a tobacco leaf collecting device through the tobacco leaf conveyor, and selection of the tobacco leaves is achieved. The device and method for automatically selecting the tobacco leaves for the cut tobacco are easy to conduct, the tobacco leaf selecting efficiency is high, and the automatic degree is high.

Description

technical field [0001] The invention belongs to the field of tobacco processing, and in particular relates to an automatic selection device and method for shredded tobacco leaves. Background technique [0002] Maintaining the purity of tobacco leaf raw materials runs through the processes of tobacco leaf purchase, threshing and redrying, and silk making, and has always been one of the key concerns of tobacco processing technology. Non-grade tobacco leaves such as blue smoke and moldy tobacco, as well as non-smoke debris such as hemp shreds, which are produced due to poor control of the picking process, poor tobacco leaf preparation, or poor moisture control during storage, etc., are mixed into the grade tobacco leaves, which will seriously affect the quality of cigarette products. Scent quality. At the same time, due to the limited efficiency of threshing air in the threshing and redrying process, some tobacco sheets containing stems enter the raw materials of cigarettes, w...

AI Technical Summary

Problems solved by technology

Manual screening one by one is time-consuming, labor-intensive, and inefficient, and the homogenization control of the purity of tobacco sheets cannot be guaranteed for long-term stability and reliability, and it is difficult to meet the needs of fine processing in the silk-making process

Therefore, judging from relevant literature reports at home and abroad, there is still no automated equipment that can uniformly solve the detection and removal functions of green smoke, moldy smoke, debris and stem-containing tobacco leaves.
