Method for grading scattered tobacco leaves on conveyor belt and production line

Abstract

The invention relates to a method for grading scattered tobacco leaves on a conveyor belt production line, which comprises the followign steps: utilizing a mechanically movable conveyor belt production line for grading, putting damping and soft raw scattered tobacco leaves on the conveyor belt, and selecting one standard grade by professional staff by contrasting grading samples. After being baked, the tobacco leaves are put into an ondol; after being changed to be soft from a brown and crisp state through damping, the tobacco leaves are packed and then sent to purchase spots. After registration and coding, the packed tobacco leaves are conveyed to a grading area, and scattered tobacco leaves in a small amount are continuously sent to the movable conveyor belt production line for grading and selecting into baskets. According to the different growing parts of a tobacco leaf, tobacco leaves are divided into five grades of primming, lugs, leaf, cutters and top leaf. According to the color of a tobacco leaf, tobacco leaves are divided into the five tobacco grades of orange, lemon yellow and varicolored, wherein the varicolored is also divided into reddish brown, cyan and brown. The method reduces the technical difficulty of grading, avoids the phenomenon of adulteration and enhances the efficiency of grading and selection.

Description

technical field [0001] The invention relates to the technical field of grading, packaging, purchasing and storage of raw tobacco leaves after baking, and in particular relates to a method for grading mixed-grade loose tobacco leaves on a transmission belt line. Background technique [0002] Tobacco leaf grading is a link with high technical requirements and large labor input in tobacco leaf processing and production. Pick out and bind according to different specifications and grades. Everyone completes the grading of all grades. The subjective randomness is relatively large, and the standards are difficult to unify and master. , and impurity to make false phenomena occur, and because of repetitive selection and boring operation methods, tobacco farmers are prone to visual fatigue, resulting in low grading efficiency and low grade purity. According to the actual production of tobacco raw materials in my country, it should be simple and easy. Positive results can be achieved. Zu...

[0002] Tobacco leaf grading is a link with high technical requirements and large labor input in tobacco leaf processing and production. Pick out and bind according to different specifications and grades. Everyone completes the grading of all grades. The subjective randomness is relatively large, and the standards are difficult to unify and master. , and impurity to make false phenomena occur, and because of repetitive selection and boring operation methods, tobacco farmers are prone to visual fatigue, resulting in low grading efficiency and low grade purity. According to the actual production of tobacco raw materials in my country, it should be simple and easy. Can achieve positive results, Zunyi County Tobacco Company adopts the method of conveyor belt flow operation, through the special tobacco leaf conveyor belt, implements tobacco leaf flow grading, and overcomes the disadvantages of traditional pure manual grading. This method has not been reported in China.
