Background
The structure of tobacco materials (tobacco shreds, tobacco flakes and tobacco stems) means the proportion of the tobacco materials with different sizes, has important influence on both cigarette quality indexes and economic indexes, and is a routine detection item in the tobacco processing process. The cigarette technical standard and the cigarette national standard have definite definition and requirements on the structures of different tobacco materials. Taking the structure of the cut tobacco as an example, the specification of the cigarette process specification is as follows: the cut tobacco with the length more than or equal to 3.35mm is a filament, the cut tobacco with the length between 2.5 and 3.35mm is a medium cut tobacco, and the cut tobacco with the length less than 1.0mm is a shredded cut tobacco; the whole tobacco shred ratio (the proportion of the tobacco shred with the length more than 2.5 mm) is more than or equal to 80 percent, and the broken tobacco shred ratio (the proportion of the tobacco shred with the length less than 1.0 mm) is less than or equal to 3 percent.
Along with the deepening of cigarette processing refinement, some problems that detection device that uses at present exists are more and more outstanding, mainly have following problem:
(1) The detection range is not suitable for needs, and no matter the pipe tobacco structure or the blade structure is used at present, the aperture span of the detection mesh is large, and a detection blind area exists. Similarly, taking the structure of the cut tobacco as an example, the current detection instrument is a three-layer vibrating screen, the mesh aperture is 3.35mm, 2.50mm and 1.0mm respectively, but actually the longest length of the cut tobacco can reach 100mm, and the specific gravity of the cut tobacco larger than 10mm can also reach about 20% on average. The screen of the current detection device is fixed, so that subdivision cannot be performed, and the current detection device is not suitable for the requirement of refinement;
(2) The detection precision is not suitable for the requirement, and the detection precision is mainly characterized in that the feeding of the conveying belt is not uniform, the material is piled when falling to the screen, the material cannot be fully screened, and the precision of the detection result is influenced. In addition, materials can be accumulated on two sides of the conveying belt, and detection errors can be amplified;
(3) The detection cost is high, and because the sizes and the shapes of tobacco materials such as cut tobacco, leaves and the like are inconsistent, each tobacco material needs an independent detection instrument, so that the equipment investment cost is increased. Meanwhile, no special detection instrument for the tobacco stems and the cut stems exists at present, and the structural proportion of the tobacco stems is detected by manual picking; the cut stem structure is detected by using a cut stem structure instrument, but actually, the cut stem is sheet-shaped, the cut leaf is filiform, and the detection result is not accurate.
The above problems are ubiquitous in the tobacco industry, and particularly with the deepening of process research and refinement, the research on tobacco shred subdivision becomes one of the hot spots of industry research, but no related detection device is available for reference at present.

When the tobacco material screening is finished, a second driving motor 501 is started, the second driving motor 501 drives a swing cylinder 508 to move back and forth on the screen plate 314 through a main transmission synchronous gear belt wheel 502, a secondary transmission synchronous gear belt wheel 503 and a synchronous toothed belt 504, and the surface of the screen plate 314 is cleaned, wherein when the brush roller shaft 507 and the brush 509 are in a horizontal state under the action of the swing cylinder 508, the screen plate synchronous cleaning device 5 does not clean the surface of the screen plate 314; when the brush roll shaft 507 and the brush 509 are in a vertical state under the action of the swing cylinder 508, the sieve plate synchronous cleaning device 5 cleans the surface of the sieve plate 314, tobacco materials hung on a net surface are cleaned and fall into the corresponding U-shaped discharge chutes 7 along with vibration screening, and finally the tobacco materials in the U-shaped discharge chutes 7 are weighed and recorded, and various proportions (such as the whole tobacco rate, the shredded tobacco rate, the large and medium tobacco slice rate, the long stalk rate, the broken stalk rate and the like) are respectively calculated according to a calculation formula.
The device can separate the tobacco materials of different sizes through loosening and vibration screening of the tobacco materials, collects the separated tobacco materials of different sizes respectively, is used for the analysis requirements of the detection materials of different sizes, improves the detection precision, reduces the detection cost simultaneously, and provides a basis for deep development of process research. The method specifically comprises the following aspects:
(1) The detection range is wide, the sieve plate can be quickly replaced in time through the optimized design, the fixation is firm, the operation is stable, the detection range is expanded through setting the shapes or sizes of different sieve pores, and the requirement of subdividing, detecting and analyzing the size of the tobacco material can be fully met;
(2) The detection precision is high, and detection errors are avoided and the detection precision is effectively improved through the design and application of the loosening device and the improvement of the conveying belt;
(3) The detection cost is low, the integrated application is realized, namely, the detection requirements of different tobacco material (leaf, leaf shred, tobacco stem and stem shred) structures are simultaneously met on one detection device, and the detection cost is effectively reduced; the power of the ratchet mechanism comes from the vibration of the screen body, which is also beneficial to reducing the power consumption;
(4) The cleaning and maintenance are convenient, the automatic cleaning of the detection sieve plate is realized through the design and application of the sieve plate cleaning device, the operation efficiency is improved, the labor intensity is reduced, and meanwhile, the detection error is favorably reduced;
(5) The transmission is steady, the noise is low, divides the net rate high, and operation maintenance is simple and convenient, and amplitude, frequency, time all can set up respectively as required, one-touch operation.
