Tobacco rib breaking machine

Abstract

The invention discloses a tobacco rib breaking machine which comprises a machine frame, a hob cutter roller, a convey rubber roller and a driving device, wherein the hob cutter roller, the convey rubber roller and the driving device are arranged on the machine frame; the driving device drives the hob cutter roller and the convey rubber roller to rotate in the reverse direction; a clearance used for breaking ribs is kept between the hob cutter roller and the convey rubber roller; and the hob cutter roller comprises a rolling shaft and circular blades fixedly sleeved on the rolling shaft. When the tobacco rib breaking machine is in use, the driving device is started firstly, the driving device drives the hob cutter roller and the convey rubber roller to rotate in the reverse direction, and the tobacco leaves are placed in the rib breaking clearance of the hob cutter roller and the convey rubber roller with the leaf veins at the thicker end facing the hob cutter roller, so that under the equidirectional dragging force generated when the hob cutter roller and the convey rubber roller rotate in the reverse direction, the tobacco leaves pass through the clearance; and during the passing process, leaf stems or chief veins which are thicker than the leaf surfaces are lacerated by the circular blades so as to realize rib breaking, and the rapid rib breaking of the tobacco is realized.

Description

technical field [0001] The invention relates to the technical field of tobacco leaf rib breaking, in particular to a tobacco leaf rib breaking machine. Background technique [0002] Among the varieties grown in tobacco, sun-dried tobacco is one of them. In the preparation process before the tobacco leaves are purchased, sun-cured yellow tobacco is different from flue-cured yellow tobacco. The process of yellowing, color fixing and tendon drying is completed in the artificially built curing barn, while sun-cured yellow tobacco is passed in the sun in a natural environment. The above three steps are completed according to certain technical requirements and experience. Since the veins of the fresh yellow tobacco leaves are thicker, especially the petiole end, it is necessary to manually cut the vein skin of the thicker end of the tobacco leaves to a certain depth before drying. The water in fresh leaves volatilizes quickly, adapting to the whole preparation requirements and sp...

AI Technical Summary

Problems solved by technology

When working, put the veins of the fresh leaves upward, and use a tendon cutter to scratch the epidermis from the veins near the leaf tip to the petiole end to break the tendons. This form of artificial tendon breaking is labor-intensive and efficient. Low, and the depth of broken ribs varies, and the operation requires a certain degree of proficiency
