Manufacture method of tobacco strips and air groove

Abstract

The invention discloses a manufacture method of tobacco strips. Cut tobacco enters a tilt-up air groove along an acceleration direction, the slope of the air groove is gradually increased along the acceleration direction so as to lift the cut tobacco, and a plurality of synchronously pivoting nozzles or singly pivoting nozzle is arranged at the bottom of the air groove so as to change the speed and the direction of an airflow which is blown out from the nozzles along the acceleration direction of the cut tobacco and converges with a cut tobacco flow at the mouth of each nozzle to accelerate the cut tobacco flow. The invention also discloses the air groove for manufacturing the tobacco strips, comprising a plurality of tilt-up corrugated soleplates at the bottom. The invention reaches the optimal flowing condition of continuously accelerated near-wall flowing when the airflow and the cut tobacco flow converge so as to obtain tobacco strips with even density. The invention is suitable for the tobacco industry and can be used in technical fields of cigarette product development, cigarette process, tobacco machinery, and the like.

Description

technical field [0001] The invention relates to the field of tobacco manufacturing, in particular to a method for manufacturing tobacco rods in the cigarette production process. The invention also relates to an air slot for the manufacture of tobacco rods. Background technique [0002] Cigarettes are tobacco products that cut tobacco leaves into thin shreds and roll the shredded tobacco with cigarette paper for people to smoke or smoke in other ways. Shredded tobacco is a mixture composed of shredded leaves, cut stems, shredded reconstituted tobacco leaves, expanded tobacco, expanded cut stems, etc., and is used for rolling cigarettes. [0003] Since the introduction of the suction forming technology in 1953, the technical method of conveying, removing impurities and forming shredded tobacco by using the wind wire feeding system has been widely used and developed. The suction forming technology is to use the air flow to form the tobacco in the tobacco box into a tobacco fl...

AI Technical Summary

Problems solved by technology

Its disadvantages are: eddy currents are formed in the cavity above the guide rail, which can easily cause some shredded tobacco to circulate in the cavity, causing the shredded tobacco to break and heat up due to friction, and even damage the flow conditions and cause shutdown

Its disadvantages are: due to the side-by-side staggered arrangement of double guide rails with different concave surfaces, resulting in differences in tobacco flow, resulting in quality deviations in the tobacco rods on the tobacco rod forming machine

Its disadvantages are: the nozzle structure is fixed and cannot be adjusted, and it cannot be adjusted in real time according to changes in production rate, fluctuations in the internal structure of shredded tobacco, and fluctuations in the quality of tobacco rods on the tobacco rod forming machine, resulting in downtime failures such as wire blocking, running rods, and rod weight deviations. And increase the consumption of raw and auxiliary materials
