Cut tobacco making method and system

Abstract

The invention discloses a cut tobacco making system. The system comprises a feeding airlock, an air pipe, a wind impact pipe, a tangential blanking device, a discharging airlock, an air return pipe and a fan; one inlet of the air pipe is connected with the feeding airlock, and the other inlet of the air pipe is connected with the air outlet of the fan; the outlet of the air pipe is connected withthe inlet of the wind impact pipe, the outlet of the wind impact pipe is connected with the tangential blanking device, the discharging port of the tangential blanking device is connected with the discharging airlock, and the air return port of the tangential blanking device is connected with the air inlet of the fan through the air return pipe; and a wind power cutter set is arranged in the windpower impact pipe and comprises a plurality of blades arranged side by side. The invention further discloses a cut tobacco making method for feeding a mixture of airflow and a material into the wind power cutter set at a preset speed and cutting. Wind energy is used for replacing mechanical shearing to achieve shredding, and the system and the method have the advantages of being low in machining requirement, long in service life, small in cutter abrasion, stable, efficient and the like.

Description

technical field [0001] The invention belongs to a shredded tobacco processing system in the tobacco industry, and more specifically relates to a shredded shredded method and system. Background technique [0002] Shredded stems are the filling material of cigarettes. The shredded stems produced by traditional techniques are mostly flakes. They are used in a relatively large proportion in middle and low-grade cigarettes, and the proportion of cut stems in high-end cigarettes is very small, or even not used. In order to increase the utilization value of cut stems, improve product quality, reduce the harmful properties of cigarettes, increase the use ratio of cut stems in high-grade cigarettes, and improve the cutting process of cut stems, so that cut stems are changed from traditional flakes to silk shape, the adjusted stem shreds and leaf shreds are closer, and the blending is more uniform. Blending the appropriate ratio of silk stems in high-grade cigarettes will not change ...

AI Technical Summary

Problems solved by technology

This type of structure is relatively simple, but the processing accuracy is very high. The thickness of the round knife and the gap between the blades are required to be no more than 0.05mm, and the cumulative error of 30 blades is ≤0.1mm. The processing difficulty is very high.

Moreover, in the process of use, the round knives will be accompanied by friction due to insufficient precision. During the friction process, the knife edge will be damaged, the blade will become blunt, and the service life of the knife will be reduced. At the same time, impurities will be dropped to pollute the raw materials.

In general, the precision requirements for processing similar tools are high, and the processing cost is too high. Moreover, due to the limited service life of friction, it is difficult for a set of tools to exceed 3 months, so it needs to be replaced for a long time, and the maintenance cost is also high. In addition, friction drops Contaminated raw materials caused by the expansion of shredded stems caused a bottleneck in the re-cutting technology. Therefore, under such a background, a reliable shredding process is urgently needed. Difficulty in processing, improve the service life of the tool, and avoid the contamination of raw materials by the friction and drop of the tool
