Description

A tobacco leaf stalk splitter for experiment line

Technical Field

The utility model relates to a tobacco processing equipment, especially a tobacco leaf stalk splitter for experiment line.

Background

Before tobacco processing enters a shredding procedure, tobacco leaves and stems are separated by a tobacco leaf and stem separator, the process is generally called threshing air separation (process equipment is called threshing lines for short) in the tobacco industry, the tobacco leaf and stem separator is generally formed by connecting four (or five) stages of threshing devices and ten (to twelve) air separators in series, and tobacco flakes and tobacco stems (or leaf veins) are separated in a step-by-step threshing step-by-step air separation mode. Unprocessed tobacco leaves firstly enter a first-stage defoliator, under the striking action of movable teeth (arranged on a toothed roller) and static teeth (fixed on a machine body), the tobacco leaves are torn and broken to a certain degree, the broken smaller tobacco leaves fall off from the basket fence hole gaps and leave the machine body, the tobacco leaves with the broken degree which is not enough (larger) are still kept in the defoliator machine body and are continuously struck until the tobacco leaves are completely broken and fall off, then the tobacco leaves enter an air separator, under the wind power flotation action of the air separator, a part of (lighter) leaves without stems are separated and leave a production line, and a part of materials with the separated parts which are not enough (the leaves in the leaves or the stems with the leaves in the stems) sequentially enter a second stage, a third stage and a fourth stage, and the leaf-striking air separation is carried out until the stems and the leaves are completely separated.
