Abstract

The invention relates to the tobacco industry, in particular, to the technique of processing tobacco waste, and can be used in the production of reconstituted tobacco. The aim of the invention is to improve the quality of the fibers when cutting the mass of reconstituted tobacco. The device comprises a stationary body 1, in which a shaper in the form of a rod 6 is installed, designed to give the tobacco mass the shape of a hollow cylinder, and plates 7 are fixed on the surface of the rod 6 for dissecting the cylinder formed from the tobacco mass. In the knife head 5 on the axis x 8, fixed with eccentricity, disk knives 9 are installed. The latter, when the knife head 5 rotates, rolls around the rod 6 and cuts off the tobacco fiber shavings formed from the tobacco mass. 1 il.

The invention relates to the production of industrial waste, and can be used in the production of regenerated tobacco.

The goal is to acquire the quality of fibers when cutting the mass of reconstituted tobacco.

The drawing shows the device structure about

The device comprises a fixed body 1, which is fixed on the body of the ganet press 2 “Inside the body of the screw press. To supply the Macci i tobacco and create the necessary pressure, a screw 3 is mounted. On a stationary housing 1, a movable knife 5 is mounted on a bearing 4 rotatably around a central axis o. Inside the stationary case -1 a central former is installed in the form of a st. rod 6 to form a narrowing annular channel. which, together with the body, is designed to give the tobacco mass the shape of a hollow zshishshr, and on its surface there are fixed plates 7 for dissecting the tobacco moldable mass of the cylinder (three splitters evenly around the perimeter of the rod 6), the disk knives 9 on the axles x 8, fixed with eccentricity, have disk knives 9 (three knives at equal distances) "Knives 9 are set in such a way that during rotation of the movable head 5 They are rolling round the rod 6. The drive of the head 5 is carried out by a belt drive, so that on the surface of the head 5 is grooved 10 an iodine V-belt,

The device operates as follows.

The tobacco mass (a mixture of shredded tobacco, adhesives, water and plasticizer) is squeezed out by screw 3) stationary case. Here, the passage between case I and the Shch11M rod 6, the mass is formed in the form of a hollow cylinder, the wall thickness of which is equal to the thickness of the tobacco 0.8 mm fibers. During the watering and molding through the image of the annular slot of the tobacco material, the plates 7 cut it into three paBin.ie parts. With nr-) pg (movable head 5 disk 9 rounds of the

the surfaces of the rod 6 and cut the tobacco-shaped chips from the tobacco mass being molded from the tobacco mass. The rotational speed of the movable head 5 and the cylinder forming speed from the tobacco mass (screw rotation speed C) are synchronized so that the width of the cut chips

Q is 0.1-0.3 mm. During operation, the disk knives gradually grind down and decrease in diameter. A gap is formed between the knives 9 and the rod 6 about this gap.

5 is carried out by adjusting the eccentric axes 8 "With them, the knives 9 are again brought to the rod 6" The cut fibers of reconstituted tobacco have a shape and dimensions close to the sizes of natural tobacco fibers Jo, 8x0.2x3 mm) "After cutting, the surface of the fibers is dried in a stream of warm air, and then the fibers are fed to the dryer, where they

5 humidity is brought to the technologically necessary (about 16%) ,,

To eliminate the gap formed between the rod 6 and the knives 9, the eccentric axis B is rotated along

0 clockwise until the knife 9 touches the rod 6o. Turning the axis 8 can be done manually at the moment of stopping the rotating head 5 1 with a plastic spring. In the latter case, the axis 8 is rotated and the clearance is adjusted automatically without rotating the rotating heads 5 o

The use of plate dividers for dissecting the core to be formed allows for the cutting of tobacco fibers of the same

5 of a predetermined length. An application for cutting the fibers of circular knives mounted in a rotating head, allows you to cut reconstituted tobacco fibers that are identical

Q sizes and configurations of high quality natural tobacco fibers. Moreover, with this method of cutting, the cutting edges of the knives of the knives are not sticking to the tobacco mass.

5 installed with eccentricity

The axial placement of the circular knives to the required position after their normal wear and tear is done quickly and accurately, which ensures a stable high quality of the final product — nare: fine fibers.

The proposed device for cutting the fibers of reconstituted tobacco makes it possible to produce high-quality artificial tobacco fiber, which is close in its parameters to natural tobacco fibers.
