Device for sorting and recycling broken cigarette paper and tobacco powder in tobacco shreds

Abstract

The invention relates to a device for sorting and recycling broken cigarette paper and tobacco powder in tobacco shreds. The device is installed on a recycling tobacco shred processing production line. A groove vibrating frame of the device achieves vibration transport of the tobacco shreds through an eccentric driving device, wherein the eccentric distance e of an eccentric wheel of the eccentric driving device is equal to 8-10mm, the material fling angle beta is equal to 8-12 degrees, and the rotating speed of the eccentric wheel is equal to 4-6rpm/s. Two layers of sieve plates are designed in the groove vibrating frame, sieve meshes of the first layer sieve plates are kidney-shaped meshes which are 3*25mm in diameter and used for filtering the tobacco shreds, the sieve meshes of the second layer sieve plates are round meshes which are 1.5mm in diameter and used for filtering the tobacco powder, and a tobacco powder outlet is designed in the bottom of the groove vibrating frame. Partition plates, splitter plates and the like are installed on the surfaces of the first layer sieve plates, air pipes and supports are designed and installed on a groove vibrating rack, and an air pressure adjusting valve is connected. A negative pressure adsorption tube is designed, when being sieved from the tobacco shreds, the broken cigarette paper is collected in a suspending mode and adsorbed under the effect of airflow, and tobacco shreds are transported to a next working procedure through a discharge groove.

Description

[0001] technical field [0002] The invention relates to a device for sorting shredded cigarette paper and tobacco powder in recycled shredded tobacco, especially for separating shredded cigarette paper, tobacco dust and shredded tobacco in recycling unqualified shredded tobacco, so as to reduce shredded cigarette paper in recycled shredded tobacco content and fines rate, improve the quality of shredded tobacco and cigarettes. It belongs to the technical field of cigarette production. Background technique [0003] In cigarette production plants in the tobacco industry, cigarette production is strictly inspected in accordance with the national standard GB56063~1996, and the company has also formulated internal control procedures for the quality of corresponding cigarettes. The inspected cigarettes are also classified as unqualified products, and the cigarettes that are taken out when the packets or sticks are damaged during the packaging process of cigarettes are also classi...

AI Technical Summary

Problems solved by technology

[0005] The tobacco industry has been making unremitting research on how to improve the recovery rate and quality of shredded tobacco in the process of recycling cigarettes. Drying, crushing, and then sorting out shredded tobacco through vibrating screens, foreign matter removal and other processes. At present, no matter which process is used, it is difficult to achieve 100% recovery of these shredded tobacco. The recycled shredded tobacco also contains a certain amount of shredded tobacco. Cigarette paper, because these shredded cigarette paper and recycled shredded tobacco are evenly mixed, it is difficult to sort manually. For this reason, some manufacturers further process the cigarettes in a crushing process, but the shredded tobacco will increase the content of tobacco powder

[0006] How to separate these shredded cigarette papers and tobacco powder from these shredded tobacco and improve the quality of shredded tobacco has always been a technical problem studied by cigarette companies. So far, there is no method to completely separate these shredded cigarette papers from these shredded tobacco. Separated, only to reduce the shredded cigarette paper content as much as possible
