Fine cigarette cut tobacco length controlling and sliver rejecting device and method for processing cut tobaccos

Abstract

The invention discloses a fine cigarette cut tobacco length controlling and sliver rejecting device and a method for processing cut tobaccos, and relates to the field of machinery. The fine cigarette cut tobacco length controlling and sliver rejecting device comprises a uniform material vibrating conveyor, a sorting and breaking area, a roll cutting area, a feeding belt conveyor, a first multifunctional winnowing box, a second multifunctional winnowing box and a discharged material lifting conveyor, wherein the first multifunctional winnowing box is arranged at the back of an outlet end of the feeding belt conveyor; the second multifunctional winnowing box is connected to the lower side of the first multifunctional winnowing box; the discharged material lifting conveyor is arranged below material outlets of the first multifunctional winnowing box and the second multifunctional winnowing box; a first circulating fan is arranged on the first multifunctional winnowing box and a second circulating fan is arranged on the second multifunctional winnowing box; and a winnowing part of the first multifunctional winnowing box communicates with a winnowing part of the second multifunctional winnowing box. By conducting primary screening and secondary screening on the cut tobaccos, qualified cut tobaccos can be finally obtained. The equipment (the device) provided by the invention, in the aspects of homogenizing and recycling the cut tobaccos and removing impurities, is smaller in occupied space, lower in energy consumption and is more concise and convenient.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a device and method for homogenizing shredded tobacco length, screening out stems from shredded tobacco, and recycling shredded shredded shreds, and more specifically, to a process and method for secondary processing of shredded tobacco, belonging to tobacco production machinery. equipment field. Background technique [0002] In the current domestic and foreign cigarette technology, shredded tobacco often contains some sundries such as tobacco stalks and agglomerated shredded tobacco, which need to be separated and removed. During processing, it is required that the shredded tobacco winnowing machine can efficiently and thoroughly remove impurities. If waste tobacco stems and impurities cannot be removed efficiently and thoroughly, it will firstly affect the continuous operation of the entire process, and secondly, it will affect the quality of the final shredded tobacco. The main compo...

AI Technical Summary

Problems solved by technology

However, no matter whether you use a drum dryer or air-flow drying equipment, because there are many filaments in the shredded tobacco, they will be entangled with each other during the drying process to form silk clusters, resulting in local uneven temperature and moisture, and the drying equipment will also be affected by temperature. Higher burnt tobacco shreds need to be removed

Existing winnowing equipment cannot loosen the filament clusters very well, shorten the filaments, make the shredded tobacco uneven, and it is difficult to remove coke flakes, stem sticks and other sundries in the shredded tobacco, and consumes a lot of energy at the same time

[0004] The main function of the existing tobacco cut tobacco winnowing machine is to sort out the stems and discard them directly. Among them, the sorted tobacco contains 1% to 2% qualified cut tobacco. The existing technology cannot be recycled, resulting in large economic losses.
