Abstract
The utility model relates to a polarization testing device for the maturity of cotton fibers. The utility model is composed of a light source, a lens matched with the light source, a photoelectric device, a display device, an optical polarization device in a light path, a neutral filter and a cotton fiber sample clamp. The utility model is characterized in that the light source is composed of a laser diode with high efficiency and an adaptive laser extender lens, and is matched with a silicon photocell detecting device with long service life and high temperature stability. Therefore, the utility model has the characteristics of good stability, good sensitivity and high reliability. The utility model can be widely used for the test of cotton gradation.
Description
The utility model relates to a kind of maturity of cotton fiber polarisation proving installation.
The Y147 type cotton fibre polarization maturation stage instrument of having listed standard GB 6099.2-85 " maturity of cotton fiber test method polariscope method " and this standard in is extensive use of in departments such as worker, agricultural, commerce and examinations of fibers.Because the used light source of this instrument is about 100 hours 6V of life-span, 15W osram lamp, and thermal value is big, cause the selenium cell generation temperature drift of photoelectric device bigger; And the depolarization that causes polaroid is easily shaken.Cause the poor stability of instrument for this reason, use inconvenience.Above-mentioned situation is difficult to adapt to the needs of Cotton in China hierarchical verification; Be difficult to adapt to current needs (new standard has been classified degree of ripeness as grade condition reference index) of carrying out new standard GB1103-1999 " cotton medium staple cotton ".People are exploring for a long time and are designing new proving installation, thirst for the good stability of instrument, the reliability height.
The purpose of this utility model is to overcome above shortcoming a kind of maturity of cotton fiber polarisation proving installation is provided, and not only solves the stability of instrument, and improves the reliability of instrument, to adapt to the needs of Cotton in China hierarchical verification.
The utility model only improves the pick-up unit of existing Y147 type cotton fibre polarization maturation stage instrument, and to replace the life-span long, highly sensitive, the temperature drift is little to its selenium cell as photoelectric device specifically, almost do not have tired silicon photocell; Tungsten lamp as light source is little with power consumption, and the life-span reaches 30,000 hours laser diode and substitutes, and considers the narrow laser beam uniform irradiation is expanded bundle with it on cotton fiber, adopts the laser beam expanding lens to be fixed on the light path.
Obviously the utility model has the advantages that good stability, highly sensitive, reliability is high, and owing to be complementary as the laser diode of light source and the silicon photocell spectrum of photoelectric device, makes also raising greatly of its sensitivity.
Provide embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is a basic structure synoptic diagram of the present utility model.
1 light source, 2 lens, 3 polarizing plates, 4 cotton fiber sample holders, 5 analyser plates, 6 photoelectric devices, 7 potentiometers, 8 display device, 9 neutral colour filters among the figure.
As shown in the figure, the utility model is by light source 1, and suitable lens 2, display device 8 and itself and the potentiometer 7 that electrically connects, constitute optical polarizer device by polarizing plate 3, analyser plate 5 in photoelectric device 6 and the light path, form with neutral colour filter and cotton fiber sample holder 4.It is characterized in that above-mentioned light source 1 is a laser diode, as model EL65 or near-infrared laser diode, and its lens 2 are laser beam expanding lens, should adopt photoelectric device 6 to be silicon photocell, select for use the temperature drift little, highly sensitive device.
Above-mentioned laser diode and receiving device as ballistic device light source 1, promptly the silicon photocell Spectral matching of photoelectric device is good, has improved detection sensitivity greatly.Above-mentioned display device 8 can adopt microammeter or digital counting device.
According to the device that the utility model proposes, under the situation that does not change existing device substantially, improved sensitivity, stability and the reliability of test, be applicable to the cotton hierarchical verification more.
