The specific embodiment
As shown in the figure, the purposes of this embodiment is the smoked sheet after the moisture regain to be carried out foreign matter separate, mainly be the caking of foreign matter such as the plastics thing that will contain in the smoked sheet, the cigarette that goes mouldy, chicken feather, stone, offal, metal object and smoked sheet, separate, to improve the degree of purity of smoked sheet with smoked sheet.
As shown in the figure, the below of apparatus for feeding 1 is the charging aperture 3-1 of casing 3, and high-speed belt conveyor 2 is connected as a single entity by frame 10 with tail band 8.Impurity removal gas lock 7 and wind locellus 6 are housed between high-speed belt conveyor 2 and the tail band 8 successively.Imaging device 2-1 is housed above or below the high-speed belt conveyor 2, and compressed air spraying device 2-2 is equipped with in the place ahead of high-speed belt conveyor 2 the both top of impurity removal gas lock 7.Casing 3 is equipped with in the top of tail band 8, and the other end of tail band 8 is equipped with discharging gas lock 9, and net 4, wind pipe 5 and external blower fan are logical to link to each other the air outlet of the top of casing 3 by changeing, and the governor motion of vertically-supplying air size in the adjustment wind locellus 6 is installed on wind pipe 5.
Apparatus for feeding 1 is layered on smoked sheet on the zone face of high-speed belt conveyor 2 equably, high-speed belt conveyor 2 drives smoked sheet and travels forward fast, form the material flow even, continuous, that thickness is suitable, because the zone face speed of high-speed belt conveyor 2 is much larger than the ordinary straps machine, therefore, on the zone face of high-speed belt conveyor 2, the layer thickness of smoked sheet is much smaller than the ordinary straps machine, phase non-overlapping copies almost, and, can adjust the layer thickness of smoked sheet easily by adjusting the zone face speed of high-speed belt conveyor 2.
Imaging device 2-1 is housed above or below the high-speed belt conveyor 2, when almost mutual nonoverlapping smoked sheet passes through from imaging device 2-1 below, imaging device 2-1 carries out data acquisition to it, and send into computer, the corresponding software of computer utilization carries out data analysis, features such as size, color, shape profile are compared, provide signal after noting abnormalities, break away from the zone face of high-speed belt conveyor 2 when smoked sheet after, compressed air spraying device 2-2 opens, high velocity air is laid foreign matter, sends equipment through impurity removal gas lock 7, has realized the rejecting to the little foreign matter of density.
Because the force limited of high velocity air, for plastics thing, the cigarette that goes mouldy, foreign matter that the chicken feather isodensity is little, reject respond wellly, then can not effectively reject for stone, offal, foreign matter that the metal object isodensity is big.
By high-speed belt conveyor 2, imaging device 2-1, the foreign matter device that compressed air spraying device 2-2 forms, and corresponding foreign matter is compared, rejecting software, is mature technology, has obtained widely applying on tobacco production line.
Smoked sheet and stone, offal, the foreign matter that the metal object isodensity is big, break away from the zone face of high-speed belt conveyor 2 after, under the effect of self inertia power, continue rapid movement forward, fall along parabola, enter wind locellus 6.
Remain vertically-supplying air from bottom to top in the wind locellus 6.Under the impelling effect of high-speed belt conveyor 2, smoked sheet is as waterfall, fast and along entering wind locellus 6, traverse locellus 6 with the perpendicular direction of vertically-supplying air, aweather another sidewall motion of locellus 6, in this process, smoked sheet density is little, and inertia force is little, windage is big, cast is near, is subjected to the vertically-supplying air long action time, changes direction of advance easily, and offal, foreign matter density such as conglomeration are big, inertia force is big, and windage is little, and cast is far away, be subjected to vertically-supplying air short action time, be not easy to change direction of advance, therefore under vertical wind action, the direction of motion of the smoked sheet that density is little has bigger change, upwards lift, enter casing 3, and the big offal of density, the direction of motion of foreign matters such as conglomeration changes smaller, can not enter casing 3, another sidewall along wind locellus 6 falls, and because the thickness of smoked sheet stream can effectively control, guarantee that smoked sheet can accept vertical wind action effectively, realized rejecting the big foreign matter of density.
So just realized the foreign matter of smoked sheet is separated.
After smoked sheet enters casing 3,, drop on lentamente on the tail band 8 progressively with flow separation, tail band 8 drive under, send casing 3 from discharging gas lock 9, enter next procedure.
Change net 4 and prevent that smoked sheet from being taken out of casing 3 by air-flow.The governor motion of adjusting vertically-supplying air size in the wind locellus 6 is installed on wind pipe 5, and the wind speed of vertically-supplying air can be less than or equal to the floating velocity of smoked sheet.Can adjust the selection by winnowing effect by the size of adjusting vertically-supplying air.
The zone face speed of high-speed belt conveyor 2 generally is controlled at 2～8 meter per seconds, and adjustable continuously in this velocity interval.
