Abstract
The utility model discloses a CO2 (carbon dioxide) expanded cut tobacco line loosening mechanism comprising a transmission groove left side guard plate (1), a transmission groove right side guard plate (4), a loosening shaft (2) and rake nails (3). Each rake nail (3) is in the shape of a circular arc which is formed in such a manner that two points are chosen on the loosening shaft (2), arc-shaped lines extend outward from the two points in the rotation direction of the loosening shaft (2), the outer arc-shaped line is longer than the inner arc-shaped line, and the outer arc-shaped line and the inner arc-shaped line intersect at a point on the outside of the loosening shaft (2). The CO2 expanded cut tobacco line loosening mechanism has the advantages of simple structure, less wear and high shock resistance and deformation resistance. The contact area of the rake nails is large and the rake nails do not fall off from the loosening shaft easily, so that the maintenance efficiency is reduced and the loosening efficiency is increased.

Expanded cut tobacco technique is an important pipe tobacco treatment technology in cigarette industry, because of its meet Modern cigarette industry to improving the pipe tobacco interior quality, the requirement that reduces costs, improve security is widely adopted, in present stage, comparative maturity and universal tobacco expanding technology can be divided into carbon dioxide expanded cut tobacco technology, freon expansion pipe tobacco technology and nitrogen expansion pipe tobacco technology with the difference of inflating medium, and the tobacco expanding utilization that the carbon dioxide of wherein take again is inflating medium is the most general.The carbon dioxide expanded cut tobacco technology is to using carbon dioxide as the tobacco thred expansion method of medium, and its advantage is that the filling value is high, can effectively remove the assorted gas in tobacco, improves the product quality of cigarette, reduces the tar content in tobacco.
Swelling cut tobacco line generally adopts on the loose axle of rotation at present, the working method of interval welding cylindrical harrow nail is broken up pipe tobacco, this cylinder harrow nail is drawn materials with low cost, easy to process, welding is simple, cylindrical harrow nail as left side in Fig. 2, but this harrow nail also has obvious shortcoming, such as, the diameter of cylinder harrow nail is less, also little with the contact-making surface of loose axle, easily cause the harrow nail premature fatigue in continuous flow procedure, reduced the firm degree of solder joint, obscission is serious, and 135 ° of bendings of columniform self existence, when such bending runs into larger dry ice pipe tobacco piece, can be sipped curved, thereby the side set phenomenon occurs, make loose link abnormal sound, damage equipment.Frequent owing to damaging, average each month, be to loose link parts finishing once, every two months, to the harrow nail repair welding of losing once, have a strong impact on normal production.
Summary of the invention
The problem existed for above-mentioned prior art, the utility model provides a kind of CO
2the loose mechanism of swelling cut tobacco line, the harrow nail in this mechanism is made circular arc, not easy to wear, more can not come off, and has reduced the maintenance of equipment number of times, has improved production efficiency.
To achieve these goals, the utility model comprises transmission slot left side backplate, transmission slot right side backplate, loose axle, harrow nail, it is characterized in that, described harrow nail is circular arc, and described circular arc is to get 2 points on loose axle, and the camber line direction from this 2 point along loose axle rotation respectively stretches out, wherein the outer arc line is longer than interior camber line, and two camber lines intersect at loose axle outside a bit.
Preferably, 2 that on loose axle, get on same circle, the center of circle of this circle is dropped on the axle center of loose axle.
Preferably, the chord length L between get on loose axle 2 chooses the value in 10～30mm, and particularly preferably, described chord length L is 20mm.
Preferably, the intersection point of described two camber lines is between 100～200mm to the vertical range H of loose axle, and particularly preferably, this vertical range H is 130mm.
Preferably, described harrow nail adopts stainless steel, and thickness is 1～10mm.
Harrow nail quantity on described loose axle is 1～20, and every two adjacent harrow nail spiral array pitch differ 10 °～90 °.
Described harrow nail is welded on loose axle.
Compared with prior art, the utility model is having following advantage: the circular arc harrow nail design that this loose mechanism adopts, the wearing and tearing of equipment are reduced, impact resistance strengthens, non-deformability is optimized, the loose efficiency of pipe tobacco is improved, moreover, the harrow nail of circular arc and loose axle contact-making surface strengthen, and the firm welding degree is strengthened, harrow nail so difficult drop-off, maintenance cycle greatly reduces, after adopting this loose mechanism, overhaul of the equipments once is reduced to annually present from original January, and production efficiency increases substantially.
