Device for screening and cutting short of long tobacco shreds

Abstract

The invention provides a device for screening and cutting short of long tobacco shreds. The device comprises a rake tooth sorting machine, a shred cutting sorting machine and a lower conveyor. The shred cutting sorting machine is arranged on the right side of the rake tooth sorting machine, the lower conveyor is arranged on the lower parts of the rake tooth sorting machine and the shred cutting sorting machine, and the rake tooth sorting machine is inclined in the mode of low in left and high in right. A main feeding pipe communicating with a discharging pipe of shred mixing equipment is arranged on the middle part of the rake tooth sorting machine, a secondary discharging pipe communicating with a left feeding port of the lower conveyor is arranged at the lower end of the rake tooth sorting machine, and a main discharging pipe is arranged at the upper end of the rake tooth sorting machine. The shred cutting sorting machine is set horizontally, a shred cutting feeding port opposite tothe lower end of the main discharging pipe is formed in the left end of the shred cutting sorting machine, and a shred cutting discharging port communicating with a middle feeding port of the lower conveyor is formed in the right end of the shred cutting sorting machine. A conveying discharging port that communicates with a feeding pipe of flavoring equipment is formed in the right end of the lower conveyor. The long tobacco shreds can be better screened from the mixed tobacco shreds, and the long tobacco shreds can be cut short.

Description

technical field [0001] The invention belongs to the technical field of tobacco production equipment, and in particular relates to a long shredded tobacco screening and cutting device. Background technique [0002] With the continuous upgrading of the market, the tobacco industry began to produce a large number of slim cigarettes and short cigarettes. The development of slim cigarettes and short cigarettes has greatly reduced the harm of tobacco to smokers, and at the same time satisfied smokers. The psychological dependence of traditional tobacco shredded tobacco is usually more than 50 mm in length, which is completely satisfactory for traditional thick cigarettes, but it is too long for thin cigarettes. Finished shredded tobacco is the main raw material of cigarette products , The requirement of the cigarette process for the structure of cut tobacco is that the ratio of long cut, short cut, broken cut and tobacco powder is 30:40:29.5:0.5 respectively. In recent years, due...

Problems solved by technology

In recent years, due to the rolling needs of slim cigarettes, short cigarettes and various special-shaped cigarettes, it has been found that some shredded tobacco with a length of more than 35 mm exists in the mixed shredded tobacco, which is not conducive to the rolling of slim cigarettes. There is no high-efficiency production equipment on the production line to cut off the shredded tobacco with a length of more than 35 mm. Without increasing the proportion of tobacco powder in the finished shredded tobacco, the ratio of long and short shreds in the shredded tobacco can be adjusted to cut off the shredded tobacco with a length of more than 35 mm. For long and short tobacco, the existing equipment cannot realize it at all, so how to design a long shredded tobacco screening and cutting device to realize the screening and cutting of long shredded tobacco has become a technical problem urgently to be solved by those skilled in the art
