Technical Field
The invention belongs to the technical field of tobacco processing, and particularly relates to a tobacco raw material cutting device and a tobacco raw material cutting method.
Background
The tobacco cutter is an electromechanical device for cutting tobacco leaves or tobacco stems into qualified cut tobacco or cut stem. The basic principle of the tobacco cutter is that the feeding motion of tobacco raw materials and the cutting rotary motion of a cutting knife roller are operated according to a certain speed ratio, and the cutting knife roller cuts the tobacco raw materials passing through a knife gate of the tobacco cutter into tobacco shreds with required width.
With the development of the times, the attention of people to health is improved year by year, and the harm of the traditional tobacco is highly valued by people. In recent years, the technology of heating non-combustible novel tobacco rapidly develops, and the heating non-combustible novel cigarette does not generate second-hand smoke and does not have open flame. The tobacco shreds used for the novel cigarette which is not burnt by heating are different from the traditional tobacco shreds, and the cigarette rod of the novel cigarette can use strip-shaped tobacco sheets which are longitudinally arranged in order, and also can use sheet tobacco shreds which are arranged in disorder. The tobacco sheet material is derived from tobacco and has the same material basis as natural tobacco. Accordingly, the related art on tobacco sheets has been developed on the market.
At present, tobacco sheets used for heating non-combustible novel cigarettes are processed by shredding in the production of cigarettes in China, most of tobacco sheets are prepared by a thick slurry method, dry papermaking or a rolling method, then the tobacco sheets are transported and stored in a roll form, and the tobacco sheets are cut off line or cut on line, so that the tobacco sheets are extruded by a traditional tobacco cutter through a feeding chain so as to be convenient for subsequent shredding, the subsequent shredding quality is influenced by glycerin flowing contained in novel tobacco under the strong extrusion of the chain, meanwhile, the smoking property of finished cigarettes is influenced, and the traditional tobacco cutter cannot meet the shredding requirement of the tobacco sheets used for heating non-combustible novel cigarettes.
The existing method for cutting tobacco sheets by adopting roll cutting can only meet the requirement of fixed-length shredding, and when the tobacco sheets are rolled by disordered tobacco sheets, the effect of rolling the real tobacco sheets cannot be achieved, the compactness of finished cigarettes is directly influenced, the sucking quantity and the sucking time are greatly reduced, and the sucking property is influenced.
