Reconstructed cut tobacco shredding and winnowing system

Abstract

The invention discloses a reconstructed cut tobacco shredding and winnowing system which comprises a high-frequency vibrating tank, a shredding device, a shred cleaning device and a blanking device. The shredding device comprises a feeding device, a shredding machine, a shell and a rack, the shred cleaning device comprises a conveying pipe and a winnowing machine, the shredding machine comprises a shredding knife and a power device, the shredding knife comprises a quick knife disc, a slow knife disc, a knife rest and a shredding frame bar, the quick knife disc and the slow knife disc are fixed on the knife rest side by side through a bearing, blades of the knife discs are arranged in a staggered manner, the power device drives the quick knife disc and the slow knife disc to be in differential running and opposite-direction rotating, cutting edges of the blades are staggered for cutting, the shredding frame bar is mounted below the quick knife disc and the slow knife disc and comprises two arc-shaped net plates which are fixedly connected, each arc-shaped net plate is provided with multiple shred-leaking square holes. By the reconstructed cut tobacco shredding and winnowing system, cut tobacco can be cut off in a fixed-length manner according to different process requirements, beating missing is avoided, beaten short cut tobacco is winnowed and purified, and clean cut tobacco uniform in size and moderate in length is output finally, so that blending uniformity of cut tobacco products is improved.

Description

technical field [0001] The invention relates to the technical field of reconstituted shredded tobacco processing equipment in the tobacco industry, in particular to a winnowing system for cutting reconstituted shredded tobacco. Background technique [0002] Reconstituted tobacco is a special tobacco product processed from raw tobacco through special processing to remove some harmful substances. It has been widely used in the tobacco industry at home and abroad. The traditional process of processing reconstituted tobacco leaves is to mix them with tobacco leaves and go through high-intensity processing procedures such as loose leaf moistening and shred drying. Restricted by its physical characteristics, reconstituted tobacco leaves are prone to mechanical crushing after high-intensity processing procedures, thereby producing a large amount of dust, which affects the personal health of on-site workers and the sanitation of the production environment; Intensive processing is e...

AI Technical Summary

Problems solved by technology

In the prior art, the shortening of reconstituted shredded tobacco is mostly based on the breaking principle. The shredded tobacco cutter usually adopts a pair of knife rollers with blades arranged at intervals and rotates in opposite directions. The length of the cut tobacco thus obtained is uneven, and the phenomenon of missing beating is serious, which eventually leads to the short shredded tobacco obtained by winnowing cannot meet the requirements of blending uniformity
