Description
Technical field
The present invention relates to the technology and the equipment of tobacco processing, relate to a kind of technology and equipment that improves length uniformity of cut tobaccos specifically.
Background technology
At present the system leaf silk technology of production of cigarettes is that loosening and gaining moisture, blade after reinforced are directly carried out chopping, and the blade size that cigar mill uses is to copy factory's control again by beating leaf, according to beating the standard (seeing YC/T146-2001) that leaf is copied again, the ratio of beating large stretch of (greater than the blade of 25.4mm) behind the leaf is more than 50%, big-and-middle (12.5～25.4mm blade is middle sheet) ratio is more than 80%, more than 96%, fragment ratio (less than the blade of 3.18mm) is below 0.5% greater than the blade ratio of 6.35mm.Discover, the blade size exists quantitative relationship (to see " cigarette process " with leaf filament length weak point, Zhang Huailing etc., China Light Industry Press), because the big or small uniformity of blade is relatively poor, cause the length uniformity of cut tobaccos after the chopping relatively poor, (see " institute of Light Engineering Institutes Of Zhengzhou newspaper " and leaf filament length degree and uniformity and cigarette consumption and manufacturing quality are closely related, 2003 (4): 62-64), for improving manufacturing quality and reducing cigarette consumption, should be by reducing the large stretch of ratio in the blade, sheet ratio in the raising, the method of control fragment ratio improves blade size uniformity, thereby obtains length uniformity leaf silk preferably.
The inhomogeneity technology of existing raising pipe tobacco (comprising Ye Si and stem) length mainly contains four kinds: first kind is that the big blade that will beat behind the leaf sifts out, send into threshing machine and beat leaf, the blade that process is beaten behind the leaf sieves and beats the leaf circular treatment again, (sees Chinese patent CN1695505A) till the no sheet in the blade after beating; Second kind is in technology for making tobacco threds, and after the moisture regain of supplied materials blade, loose and reinforced processing, the blade that sieves out greater than 6.35mm carries out chopping, will be incorporated into less than the blade of 6.35mm to cut in the posterior lobe silk; The third is on the basis of second method, changes the filament cutter blade shapes, and by on filament cutter blade lengths direction blade being set, posterior lobe filament length degree is cut in control; The 4th kind is a kind of method that improves homogeneity of stalk shreds, be that long filament with against regulation size in the stem after the dry expansion sifts out, send into even silk device and carry out break process, sieve again and broken circular treatment through the stem behind the even silk, till stem is of the required size, (see Chinese patent CN101019688A).
The defective of above technology has: though 1. first kind of technology reduced the ratio of big blade on the whole, but adopt the processing mode of beating leaf, the blade size is difficult to control, beats still to have the certain ratio sheet in the rear blade, fragment rate also increases, and blade size uniformity is relatively poor; 2. second kind of technology be on the one hand because blade excessive (greater than the blade ratio of 25.4mm more than 50%), causes that to cut the posterior lobe silk long, causes in the leaf silk dry run and be easy to generate conglomeration and wrapping phenomena, is unfavorable for that high-speed cigarette machine rolls; Because in the process of sifting out less than the 6.35mm blade, the flow of blade is excessive, screening efficiency is lower, causes do not sift out higher less than 6.35mm blade broken rate in the chopping process, has influenced manufacturing quality and raw material availability on the other hand.3. the third technology can reduce leaf filament length degree, but has also increased the ratio of broken leaf silk, the blade structure more complicated of while filament cutter, and the blade manufacturing cost is higher, and maintenance and use difficulty are bigger.Though 4. the 4th kind of technology can improve the stem dimensional homogeneity, but being suitable for, the method do not handle the leaf silk, reason is that stem mostly is sheet, and the leaf silk is thread, width is about 1mm, only is that length is variant, if adopt bolting leaf silk, super sieve, to leak sieve ratio more serious, and the length uniformity of cut tobaccos after the processing is still relatively poor.
