A waste cigarette shredded tobacco recovery device

Abstract

The invention relates to a recovery device for waste cigarettes and shredded tobacco, which comprises a cigarette straightening device, a tobacco cutting device, a shredded tobacco-dirty separation device and a shredded tobacco purification device. Incoming waste cigarettes are separated from shredded tobacco debris in the straightening device, and the cigarettes are straightened and then sent to a cutting device for cigarettes. In the cutting device, they are positioned, rolled, and completely cut, and then shredded tobacco, filter tips, and tobacco paper are sent to the shredded tobacco-dirty separation device for preliminary separation of shredded tobacco and large-sized sundries. Then the separated shredded tobacco is sent to the shredded tobacco purification device again to further separate fine paper scraps and other sundries in the shredded tobacco. The device for recovering waste cigarettes and shredded tobacco in the present invention has the advantages of high degree of mechanization, high efficiency of shredded tobacco recycling, complete separation, applicable to various kinds of cigarettes, and small occupied space.

Description

technical field [0001] The invention relates to the field of tobacco machinery, in particular to a device for recovering shredded tobacco from waste cigarettes. Background technique [0002] According to the current technological level, about 0.1-1% of unqualified cigarettes will inevitably be produced in the cigarette production process, and the accumulated waste smoke cannot be ignored. There have been many processes before, which can be directly recycled and wrapped again; in order to reduce damage and increase efficiency, cigarette factories generally collect waste cigarettes for centralized treatment, and the processed cut tobacco is blended and downgraded for use. [0003] At present, there are generally two ways to deal with waste cigarettes in cigarette factories. One is manual treatment, that is, manual stripping of waste cigarettes, and the other is mechanical treatment. Due to the relatively large amount of waste produced in the production process, manual process...

AI Technical Summary

Problems solved by technology

Judging from the actual treatment effect, there are three disadvantages in this treatment method: one is that the shredded tobacco is greatly broken, the structure cannot be guaranteed, and the utilization rate is low; The purity of shredded tobacco cannot be guaranteed during utilization, which affects the internal quality of cigarettes. Third, the waste paper after treatment contains a large amount of shredded tobacco, resulting in waste of shredded tobacco

[0004] In addition, recently there have been some machines that do not rely on impact, collision, etc. to process waste cigarettes. For example, the Chinese invention patent announcement document CN105167179B discloses a waste cigarette shredded tobacco recovery system, which includes waste cigarette screening and straightening, waste smoke The cutting device, waste cigarette loosening device, waste smoke vibrating screening device and other devices process cigarettes by cutting, and the recovery effect of shredded tobacco is improved to a certain extent, but due to unreasonable design, the cutting effect is poor 1. The recovery rate of shredded tobacco is low, and it cannot be applied to cigarette paper sizes of various specifications. It can only be processed in a centralized manner with multiple specifications and batches of waste cigarettes, resulting in waste of downgraded shredded tobacco; the separation process after cutting lacks fine separation procedures, Inevitably, there will be a lot of paper scraps mixed in the recycled shredded tobacco; and the overall structure is not compact, and the equipment is bulky, so it is not suitable for online use
