Tobacco shred cutting method using water cutting machine and device thereof

Abstract

The invention belongs to the technical field of tobacco shred processing in the cigarette manufacture, and more particularly relates to a method for cutting the tobacco shred by a water jet and a device thereof. The method for cutting the tobacco shred by the water jet comprises: 1. tobacco leaves are prepared; 2. the tobacco leaves are put into a delivery mechanism of the device for cutting the tobacco shred to be conveyed to the cut position of the water jet; 3. high-pressure water sprayed out by a nozzle forms a water shooting flow jet to lead the tobacco leaves to be cut into the tobacco shred; 4. the cut tobacco shred are conveyed to the next working procedure; 5. after being cut by the high-pressure water, the tobacco shred enters a water recovery machine. The method is managed and controlled by a computer. The device for cutting the tobacco shred by the water jet is provided with a main conveyer belt and a carding conveyer belt on a frame, wherein, the carding conveyer belt is inclined, rotation shafts of the main conveyer belt and the carding conveyer belt are respectively connected with a motor shaft, and the sides of the two conveyer belts are provided with side baffles; the upper part of a manhole and the frame are connected with a guideway which is provided with the nozzle of the water jet, a control device is arranged on the frame, and the water recovery device is arranged under the manhole; the main conveyer belt, the carding conveyer belt, the nozzle of the water jet and a motion control device of the nozzle are connected with a appliance of the computer. The invention can maintain the active ingredients in the tobacco leaf to the utmost extent, improves the quality of the tobacco shred, simplifies the technique for tobacco shred processing, saves energy, reduces consumption and the cost for manufacturing the tobacco shred, and can be used for the planted tobacco leaf and artificial tobacco sheet.

Description

technical field [0001] The invention belongs to the technical field of shredded tobacco processing in cigarette manufacturing, in particular to a method and equipment for cutting shredded tobacco with a water knife. Background technique [0002] High-pressure water jet cutting is to increase the pressure of the water flow to more than 400MPa, so that the water flow speed exceeds twice the speed of sound. The jet has great kinetic energy and can penetrate materials of various strengths to achieve the purpose of cutting. Because its cutting medium is water flow, it is commonly known as "water jet". The waterjet cutting process does not generate significant heat, so it is also called a cold cutting process. The water cutting process has the following advantages: water jet cutting objects are all-encompassing, from gel to high hardness or high elastic materials and special structural materials, it can be cut conveniently and at high speed, so it has the reputation of universal ...

AI Technical Summary

Problems solved by technology

The existing tobacco cutting machine adopts mechanical shearing. During the cutting process, the cutting knife will squeeze the tobacco leaves, causing great damage to the internal fiber tissue and cell structure of the tobacco leaves. Due to the extrusion of the tobacco leaves, the tobacco leaves Part of the e-liquid in the smoke will be squeezed out, which will change the color of the cut tobacco and affect the inner quality and appearance quality of the cut tobacco

The mechanical cutting machine needs to sharpen the metal blade with a grinding wheel frequently when cutting tobacco leaves. During this process, the grinding dust of the metal and the grinding wheel enters the shredded tobacco, which will also affect the quality of the shredded tobacco.
