Abstract
An online pipe tobacco filling value measuring meter comprises a thickness test mechanism equipped on a rack and a computer process displaying device, wherein the rack is also equipped with a radiation source positioned above the pipe tobacco flow, the lower position of the pipe tobacco flow corresponding to the radiation source is equipped with a radiation detector, and the radiation detector is connected with a computer through a signal processor. The pipe tobacco filling value tested by the utility model has high accuracy, and can really play the function of guiding the production.
Description
The utility model relates to a kind of device that tobacco quality parameter in the production of cigarettes is detected, and especially relates to a kind of on-line determination instrument of measuring tobacco fill value.
Tobacco fill value is to estimate the important indicator of tobacco quality, the cigarette that the pipe tobacco that the filling value is big rolls, the consumption of pipe tobacco is few, when burning and sucking, little and the features good taste of tar, nicotine and carbon monoxide content in the flue gas, so filling value size is all significant concerning factory and consumer.The mensuration of filling value need detect the quality and the thickness of pipe tobacco in the compressive region simultaneously, and accurate quality, the thickness that detects the pipe tobacco that flows is key and difficult point on production line.A kind of product that present online tobacco fill value analyzer only has Germany to produce, to compare measuring accuracy with filling pH-value determination pH instrument lower but it is with the laboratory, can not effectively instruct production.The flow signal that this instrument transmits with belt bar is converted into the tobacco quality value in conjunction with time of manifold collection.Thickness is with the round roller of three roll extrusion on pipe tobacco, monitors that its changing up and down on tobacco stream measures.Because the transversal section of the tobacco stream that travelling belt is carried is very irregular, and press limited (the width 50mm of single round roller of width of the round roller of pipe tobacco, three round roller overall widths are 150mm, only be about sixth of conveying belt width), so when the thickness that each pressure roller of a certain moment is recorded as known, extrapolate the mass value of that part of pipe tobacco under each pressure roller effect with the flow of tobacco of belt bar, big error must be arranged, the precision of the tobacco fill value of trying to achieve thus is not high yet certainly.
The online filling pH-value determination pH instrument that provides a kind of precision higher is provided the purpose of this utility model, so that really play the effect of producing of instructing.
For achieving the above object, the utility model adopts following technical scheme: a kind of online tobacco fill value analyzer, comprise the mechanism for measuring thick, signal processor and the Computer Processing display device that are contained on the frame, the radioactive source that is positioned at above the tobacco stream also is being housed on the frame, radiation detector is equipped with in position corresponding with radioactive source below tobacco stream, and radiation detector links to each other with computing machine through signal processor.
The pressure roller that mechanism for measuring thick comprises the angular displacement sensor that is contained on the frame, be connected by movable rod with angular displacement sensor and the cylinder mechanism of control pressure roller working position.
Radioactive source and pressure roller overlap point-blank the effect track of tobacco stream.
Radioactive source is equipped with the self-acting valve with the cylinder mechanism interlock.
The infrared temperature sensor and the infrared ray Moisture Meter that link to each other with computing machine also are housed on the frame.
The isotope radiation exposure material that the utility model produces with radioactive source, the ray part that total amount is certain is absorbed by material, remainder penetrates material, measure the quantity that sees through ray, just can try to achieve the quantity that absorbs ray, and it is closely related to be absorbed the quality of the amount of ray and material, in view of the above just can be in the hope of the quality of material, the thickness of the tobacco stream measured in conjunction with the pressure roller mechanism for measuring thick of quality just can draw accurate tobacco fill value thus.The mass value of the pipe tobacco that the utility model employing isotope assay device is measured is compared with the pressurized tobacco quality value of extrapolating according to the flow of tobacco that adopts belt conveyer scale to measure, and precision improves a lot.Therefore the tobacco fill value precision height that adopts the utility model to measure can really play the effect of producing of instructing.
Further specify the utility model below in conjunction with accompanying drawing and by embodiment:
Fig. 1 is the structural representation of embodiment;
Fig. 2 is the left view of Fig. 1.
Embodiment: on the frame 12 of online tobacco fill value analyzer angular displacement sensor 4 is housed, it is connected by movable rod 2 with pressure roller 1, connecting rod 2 also be contained in frame on cylinder mechanism 3 be connected.Do not lift by cylinder mechanism 3 when the pressure roller of thickness measuring and connecting rod are not worked, put down during work.Radioactive source 5 is housed on methods, rack on the tobacco stream 11, and corresponding source positions is equipped with radiation detector 6 below tobacco stream, for safety, radioactive source is equipped with self-acting valve, and it can link with cylinder mechanism 3, just make it open valve when work.For accurately measuring the mass value of pressurized pipe tobacco, radioactive source and pressure roller overlap point-blank to the track of pipe tobacco effect.
The isotope of radioactive source adopts americium Am
241, it is a kind of low-energy photon source, and the energy of ray is 60KeV, and intensity is 50-100mCi, is suitable for detecting on production line the quality of pipe tobacco.Radiation detector uses the detector of thin window ionization chamber or other type, in the hope of response and higher degree of accuracy are fast arranged.
During work, pressure roller rolls on tobacco stream, what and fluctuate with the size variation of and filling value of pipe tobacco, this height change is passed to the filling value that Computer Processing display device 9 is used for calculating pipe tobacco by connecting rod, angular displacement sensor, radiation detector 6 receives the ray that sees through pipe tobacco and exports weak current, amplify and be converted to pulse signal input Computer Processing display device through signal processor, the number of pulse is directly proportional with the quantity of X-rays X of radiation detector reception.Computing machine contrasts this umber of pulse and " umber of pulse and the tobacco quality value " relation curve that obtains by materials calibration in advance, can draw corresponding tobacco quality value, the thickness of the pressurized pipe tobacco of being measured by this mass value and mechanism for measuring thick can be measured the filling value of pressurized pipe tobacco.
Consider filling value and the temperature of pipe tobacco and the relation of moisture of pipe tobacco, this analyzer also is furnished with infrared temperature sensor 7 and infrared ray Moisture Meter 8, provide the temperature of pressurized pipe tobacco and moisture value to computing machine 9 by them, computing machine is according to the relation curve of filling value and temperature, moisture, to calculate by quality and thickness the filling value revise, to obtain tobacco fill value accurately.Certainly, if all conformance with standard value requirements of the temperature of workshop and moisture in cut tobacco then no longer need to be equipped with temperature sensor and Moisture Meter.
