Fresh tobacco leaf petiole sectioning and orderly clamping device and its sectioning and clamping method

Abstract

The invention discloses a fresh tobacco leaf stalk sectioning and orderly-clamping device and a sectioning and clamping method thereof. Leaf stalks and tobacco leaves are different in flue-curing degree, and accordingly the flue-curing quality is affected. The fresh tobacco leaf stalk sectioning and orderly-clamping device comprises a positioning adjusting assembly, a first belt conveying mechanism, guiding plates, a compressing contour wheel, a Y-shaped cutter, a photoelectric sensor, a second belt conveying mechanism, a fastener, a tobacco clamp and a baffle. The Y-shaped cutter begins to cut main veins from the end faces of tobacco leaf stalks, and the compressing contour wheel is adjusted through a spring to adapt to the different height situations at different positions of the tobaccoleaf main veins. Sectioned tobacco leaves are throwed and conveyed through the first belt conveying mechanism, and leaf stalks fall between two adjacent clamping columns of the tobacco clamp after being in contact with the baffle; when n tobacco leaves are stacked between the two adjacent clamping columns, the tobacco clamp is stepped for one station; when the tobacco clamp is full of tobacco leaves, a motor is driven to stop rotating, the tobacco clamp is taken down and put in a flue-curing room, then a new tobacco clamp is clamped on two fasteners located at an upper tobacco leaf clamping station. The fresh tobacco leaf stalk sectioning and orderly-clamping device achieves automatic and orderly clamping of fresh tobacco leaves and makes the leaf stalk flue-curing time approximate to leaf flue-curing time.

Description

technical field

[0001] The invention belongs to the field of tobacco processing, and in particular relates to a fresh tobacco leaf petiole cutting and orderly clamping device and a cutting and clamping method thereof. Background technique

[0002] Flue-cured tobacco, that is, the curing of fresh tobacco leaves, is a process in which the tobacco leaves are dehydrated and dried by controlling the temperature, humidity and ventilation conditions in the curing room, and become tobacco leaves with certain quality, style and grade standards. The water content of the tobacco leaves changes from 80% to 90% of the expanded state to wither and dry until the whole leaf is scorched. Flue-cured tobacco is one of the important processes in the cigarette processing process in my country, and it is also the process that consumes the most energy. At present, the flue-cured tobacco is made by placing the fresh tobacco leaves on the tobacco holder in an orderly manner manually, and putting th...
