Description

Constant temperature control supply limiting tube photoelectric blowing device for compressed air of air storage cylinder

Technical Field

The utility model relates to a cigarette production facility technical field especially relates to an air cylinder compressed air constant temperature control supplies with limit buret photoelectricity jetting device.

Background

At present, cut tobacco leaves on a tobacco shred manufacturing line in the field of cigarettes are conveyed into a limiting pipe through a belt conveyor, and two sides of the limiting pipe are in opposite emission type photoelectric control to start and stop feeding. Because the cut tobacco leaves enter the limiting tube and fall onto the belt of the electronic scale with a certain fall, the tobacco dust contained in the tobacco leaves splashes on the organic glass plates at two sides of the limiting tube, and after a certain thickness is accumulated, the cut tobacco leaves can block photoelectric detection light sources at two sides to cause material breakage to influence the flow stability of the electronic scale. Meanwhile, when the cut tobacco falls into the cross section of the limiting pipe through the belt conveyor, the middle of the cut tobacco is high, the two sides of the cut tobacco are low, the cut tobacco is not pre-compacted in the limiting pipe, and the surfaces of the cut tobacco form a state of loose wave crests and wave troughs when the cut tobacco moves forwards along with the belt scale, so that the flow of the electronic scale is frequently fluctuated. Meanwhile, the infrared moisture meter has very high detection sensitivity, the amount of moisture is detected and fed back mainly by the amount of moisture wavelength in infrared absorption cut tobacco, and the moisture detection at a closer distance is more sensitive and the detection at a farther distance is weaker. Therefore, the thickness of the leaf shreds measured on the electronic scale is required to be uniform, the surface is flat and solid, and the phenomenon of cracks and unevenness does not exist, and the factors are very important for the reality and the stability of the detection data of the moisture meter.

Meanwhile, the flow of the cut leaf shred electronic scale and the water content stability seriously affect the water content control at the outlet of the cut tobacco dryer, the water content of the cut leaf shred entering the cut tobacco dryer is about 23 percent, the water content at the outlet of the cut leaf shred passing the cut tobacco dryer reaches about 13.5 percent, 10 percent of water content needs to be removed in the process, and the stable fluctuation of the water content of the incoming material is required to be small. The moisture of the cut tobacco after drying directly influences the completion of indexes such as filling value, curling degree, elasticity and the like of the finished cut tobacco of the cigarette. Is also the most important assessment index for measuring the processing in the silk making process. In the moisture control process of the cut-tobacco drier, a PLC system is required to adjust the temperature of a drying cylinder, hot air and the opening degree of a moisture exhaust valve by referring to the flow of a front-mounted electronic scale and the moisture of incoming materials, and the moisture setting requirement of an outlet is realized through calculation, so that the instability of the front-mounted flow and the moisture requires the PLC to frequently make valve instruction adjustment, and meanwhile, the interlocking reaction of outlet moisture fluctuation is also caused. The qualification rate of the export water assessment standard deviation is seriously influenced, and the product quality and the homogenization requirement are also influenced.

Therefore, there is a need for an electro-optical blowing device for a constant temperature controlled supply limiting tube of compressed air from an air reservoir.
