The AOTF/ (NIR) near-infrared spectrograph ultimately causes measurement result inaccurate, owing to small signal acquisition area and less information receiving amount. The utility model has the technical proposal that a bracing frame 21 is respectively fixed with speed reducing motors 1 and 6, a rack 3 which is arranged in the slide track 4 of the bracing frame 21 is meshed with the tooth gear 2 of the speed reducing motor 1, and a toothed rack 3 is fixedly connected with elevation and subsidence cartridge 5. The speed reducing motor 6 is coaxially connected with a tooth gear 8, the tooth gear 8 is respectively meshed with a tooth gear 7 and a tooth gear 16, an eccentric sheave 9 is coaxially connected with the tooth gear 7, and an eccentric sheave 15 is coaxial coupled with the tooth gear 16. A rotary table 14 inserting with a sample cell 12 is fixedly connected with the eccentric sheave 9 and the eccentric sheave 15 via an axis 10 and an axis 13. The experiment platform for near and far infrared spectrograph has the advantages that the area of signal acquisition of the experimental bench is enlarged, measuring accuracy has great improvement, and area of sample-taking is nearly 19 times than before.
Description
Technical field: the utility model relates to spectrometer experiment table gear train technical field, is the special-purpose experiment table of near infrared spectrometer more specifically.
Background technology: AOTF/ (NIR) near infrared spectrometer is when setting up data model and actual detected unknown materials, originally adopt fixed point collected specimens signal method, because the collection area of signal is little, the 6mm diameter is only arranged, the quantity of information of collecting is few, adds the difference of the inhomogeneous and artificial dress sample of sample itself, produces very big systematic error and personal error, finally cause measurement result inaccurate, can't satisfy the requirement of result of use.
Summary of the invention: for overcoming above-mentioned shortcoming, the purpose of this utility model is the special-purpose experiment table of a kind of near infrared spectrometer of design.Its technical scheme is: cabinet 23 internal fixation have bracing frame 21 and control circuit 22 are arranged, and are fixed with reducing motor 1 and 6 on the bracing frame 21 respectively, have the tooth bar 3 and the gear 2 of reducing motor 1 to mesh in the slideway 4 of bracing frame 21, and tooth bar 3 is fixedlyed connected with lifting tube 5; Reducing motor 6 and 8 coaxial connections of gear, gear 8 meshes with gear 7 and gear 16 respectively, eccentric wheel 9 and 7 coaxial connections of gear, eccentric wheel 15 and 16 coaxial connections of gear, the rotary table 14 that is plugged with sample cell 12 are fixedlyed connected with eccentric wheel 15 with eccentric wheel 9 by axle 10 and spools 13 respectively; Bracing frame 21 is provided with optoelectronic switch 17 and 18, and rotary table is provided with near switch 11.The advantage of this utility model is: " the special-purpose experiment table of AOTF/ (NIR) near infrared spectrometer " is in measuring process, adopted the dynamic acquisition signal, after loading onto sample, sample cell is done at 0.3～0.5 millimeter place of measurement mouth of distance near infrared spectrometer and is horizontally rotated, so just enlarge the signals collecting area of AOTF near infrared spectrometer, and then reduced the systematic error of the unevenness generation of personal error that dress sample process brings and sample itself.Therefore, measuring accuracy has had large increase.Sampling area is in the past 19 times approximately, has increased the quantity of information of sample collecting greatly.Used after the special-purpose experiment table, average analytical error relatively is lower than 3%, and the reproduction variation of repeated measurement is lower than 1%.Its structural design is novel unique, and nimbly and freely simple to operation, manufacturing expense is low, is convenient to penetration and promotion.
Description of drawings: Fig. 1 is the utility model structural representation, and Fig. 2 is this special use experiment table drive mechanism enlarged diagram.In the accompanying drawing: 1, reducing motor, 2, gear, 3, tooth bar, 4, slideway, 5, lifting tube, 6, reducing motor, 7, gear, 8, gear, 9, eccentric wheel, 10, axle, 11, near switch, 12, sample cell, 13, axle, 14, rotary table, 15, eccentric wheel, 16, gear, 17, optoelectronic switch, 18, optoelectronic switch, 19, the near infrared spectrum instrument bracket, 20, support column, 21, bracing frame, 22, control circuit, 23, cabinet.
Embodiment: cabinet 23 internal fixation have bracing frame 21 and control circuit 22 are arranged, and are fixed with reducing motor 1 and 6 on the bracing frame 21 respectively, have the tooth bar 3 and the gear 2 of reducing motor 1 to mesh in the slideway 4 of bracing frame 21, and tooth bar 3 is fixedlyed connected with lifting tube 5; Reducing motor 6 and 8 coaxial connections of gear, gear 8 meshes with gear 7 and gear 16 respectively, eccentric wheel 9 and 7 coaxial connections of gear, eccentric wheel 15 and 16 coaxial connections of gear, the rotary table 14 that is plugged with sample cell 12 are fixedlyed connected with eccentric wheel 15 with eccentric wheel 9 by axle 10 and spools 13 respectively; Bracing frame 21 is provided with optoelectronic switch 17 and 18, and rotary table is provided with near switch 11.
It is as follows to manipulate process:
(1) when AOTF/ (NIR) near infrared spectrometer is put near infrared spectrum instrument bracket 19, when connecting the 220V AC power, this " the special-purpose experiment table of AOTF/ (NIR) near infrared spectrometer " enters duty.C1 normally closed contact connection+12V direct supply in the control circuit 22, reducing motor 1 counter-rotating drives tooth bar 3 by gear 2 and makes down rectilinear motion of lifting tube 5, when movement position arrives positive stop end optoelectronic switch 18, normally closed contact C2 action, reducing motor 1 quits work.
(2) when sample cell 12 is put into rotary table 14, near switch 11 actions, C1 normally closed contact closure, reducing motor 1 is just changeing, drive tooth bar 3 by gear 2 and make up rectilinear motion of lifting tube 5, reducing motor 1 quits work, normally opened contact C3 connects reducing motor 6 simultaneously, by gear 8 driven gears 7 and 16 and eccentric wheel 9 and 15 do synchronous rotation, it is moving apart from 0.3～0.5 millimeter horizontal circle of measurement mouth of near infrared spectrometer transhipment of socializing to be connected rotary table 14 and sample cell 12 with 13 by axle 10, and finishes test job.
