Abstract

A color photometer for a colored cotton is characterized in that a tinct sensor 5 adopts a XYZ three-color sensor; an amplifier 6 comprises the three amplifiers correspondingly connected with the XYZ three-color sensor; a standard tinct plate 9 is successively a white plate, a red plate, a yellow plate, a green plate, a blue plate, which is arranged in turn on a testing window 3; the XYZ three-color sensor outputs the information measured of the standard tinct plate sequentially; the information is sent to a computer and an output device 8 through the amplifier 6 and an interface circuit RS 232, so as to set up a standard of a color space of the instrument; the colored cotton 10 apostrophe is arranged at the testing window 3; a lock block 11 is pressed on the colored cotton 10 apostrophe; a color measurement result is displayed by the computer and the output device 8. Compare with a prior art, the utility model has the advantages of that 1, the color photometer of the colored cotton is provided firstly to measure a chroma and a color aberration of the colored cotton high precisely; 2, the standard tinct plate of the colored cotton is provided to set up the standard of the color space of the instrument; 3, the measurement of the color photometer has a good precision and repetitiveness; 4, the color photometer can be used in the test of the tinct of not only the colored cotton but also a white cotton.

Description

The color cotton colour photometer

Technical field

The utility model relates to a kind of color measuring device, particularly a kind of color cotton colour photometer.

Background technology

Color cotton is the new cotton variety that artificial culture comes out, the Chinese science man utilizes multiple means such as hybridization, systematic breeding, cultivated serial color cotton variety, these color cotton varieties not only the output height, color is pure, disease resistance is strong, easy large tracts of land popularizing planting, and fiber quality is good, finish and meet the textile requirement, reached world-leading level.Color cotton has the peculiar quality of the nontoxic pollution-free that need not to print and dye, and along with continually strengthening of world's environmental consciousness, " green product " consumption becomes fashion day by day, and color cotton seed is planted and color cotton spinning constantly develops into a new industry.The color ginnings of China accounts for 1/3rd of world wide production, is maximum in the world color cotton producing country.The scholarly forecast of the United Nations Industrial Development Organization, to the year two thousand thirty, color ginnings will reach about 10% of world's ginnings, above 2,000,000 tons.

As everyone knows, its structure of white cotton colorimeter as shown in Figure 1 and Figure 2, pedestal 1 is fixed on housing 2 base plates, above the housing 2 that test window 3 is arranged in, light source 4, light hurdle group 5, shutter 6 are installed in respectively on the pedestal 1, wherein light source 4 to the angle between test window 3 central point lines and this central point vertical line is 45 °, color and luster sensor 5 adopts YZ two look sensors, be arranged on the bottom surface of housing 2, the output information of two look sensors delivers to computing machine respectively behind amplifier 6, interface circuit 7 and output device 8 shows and printing; Before the colour examining of white cotton, the neutral plate, blank, yellow plate, Petiolus Trachycarpi, the hawk that constitute white cotton Standard colour board 9 are arranged on the test window 3 successively by turns, and the relevant detection data are shown by computing machine and output device 8 records thereof; Tested white cotton 10 places on the test window 3, and briquetting 11 is pressed in white cotton and takes; Interface circuit 7 adopts RS232, and light source 4 is powered by stabilized current supply.

Yet also successfully do not develop the instrument of color cotton color and luster grade assessment at present both at home and abroad, and the artificial visual grade assessment causes error easily owing to be subjected to the influence of uncertain factors such as human factor reaches in time, space change, is difficult to make objective evaluation.

Summary of the invention

A kind of color cotton colour photometer, comprise pedestal 1, housing 2, test window 3, light source 4, color and luster sensor 5, amplifier 6, interface circuit 7, computing machine and output device 8 thereof, Standard colour board 9, it is characterized in that: color and luster sensor 5 adopts the XYZ three-colour sensors, amplifier 6 comprise three respectively with the amplifier of the corresponding connection of XYZ three-colour sensor, Standard colour board 9 is followed successively by blank, red plate, yellow plate, green plate, blue plate, they place on the test window 3 successively by turns, and the information of XYZ three-colour sensor output is respectively through amplifier 6, deliver to computing machine and output device 8 record demonstrations thereof behind the interface circuit RS232; Tested color cotton places on the test window 3, and briquetting 11 is pressed on the color cotton 10 ', and the colour examining result is shown by computing machine and output device 8 thereof or prints.As shown in Figure 3, Figure 4

With prior art relatively, the utlity model has following advantage: 1) take the lead in providing a kind of color cotton colour photometer, can carry out high-precision color and luster grade assessment to colourity, the aberration of color cotton; 2) provide color cotton Standard colour board, the surface color of this Standard colour board is even and matt, is used to set up the color space benchmark of instrument; 3) instrument has good grade assessment degree of accuracy and repeatability; 4) this instrument both can be used for the test of color cotton color and luster, also can be used for white cotton color test.

Embodiment

Embodiment:

A kind of color cotton colour photometer, as shown in Figure 3, Figure 4, color and luster sensor 5 adopts the XYZ three-colour sensor, amplifier 8 comprise three respectively with the amplifier of the corresponding connection of XYZ three-colour sensor, Standard colour board 9 comprises blank, red plate, yellow plate, green plate, blue plate, colour table is of a size of 120 * 120 * 8mm, five colour tables are placed on the test window 3 by turns, XYZ three-colour sensor output corresponding color domain information, deliver to computing machine and output device 8 thereof through amplifier 6, interface circuit 7 respectively, set up the color space benchmark of instrument; The colourity that the color cotton colour photometer is measured, aberration are shown by computing machine and output device 8 thereof.

The colour gamut (colourity Yxy, aberration Δ E=0.0) that this instrument detecting goes out Standard colour board is as follows;

Blank colourity Y=83.64 x=0.321 y=0.339

Red plate colourity Y=14.44 x=0.541 y=0.333

Yellow plate colourity Y=60.60 x=0.410 y=0.443

Green plate colourity Y=14.97 x=0.277 y=0.431
