Description
Technical field
The utility model relates to a kind of instrument that is used to test textile, especially for the instrument of test ultraviolet resistance of fabric.
Background technology
It has been recognized that excessive ultraviolet ray irradiation is to human body skin and immune deleterious effect, to the performance pay attention to day by day of textile shielding of ultraviolet.The CARY50 that the domestic existing instrument that is used to test ultraviolet resistance of fabric has the U.S. to produce.The structure of this kind instrument is: an airtight casing is arranged, integrating sphere is housed in the casing, integrating sphere up is optical filter and ultraviolet source successively vertically, can put into tested textile between integrating sphere and the optical filter.During test, the light that ultraviolet source penetrates penetrates by optical filter and to be integrated ball behind the tested textile and to collect, and integrating sphere divides the two-way output signal, and one the tunnel through reference detector, amplifying circuit and photoelectric commutator input microcomputer; Another road is through beam splitting system, signal sensor, amplifying circuit and photoelectric commutator input microcomputer.Microcomputer is then analyzed comparison and calculating to the two-way input signal, provides test result at last.Though this kind instrument can be used for the test of textile, tested textile will insert the test position between integrating sphere and the optical filter during owing to test, makes troubles to work.Price of complete machine is also higher.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of improvement of ultraviolet resistance tester is provided, and this kind instrument should have characteristics easy to use and that cost is low.
The technical scheme that the utility model proposes is:
A kind of ultraviolet resistance tester, comprise a microcomputer and an airtight casing, ultraviolet source, optical filter and integrating sphere are corresponding from top to bottom in the casing arranges, integrating sphere divides the two-way output signal, one the tunnel through reference detector, amplifying circuit and photoelectric commutator input microcomputer, power supply also is equipped with through beam splitting system, signal sensor, amplifying circuit and photoelectric commutator input microcomputer in another road in the casing;
The drawer type specimen mounting is housed between described optical filter and the integrating sphere.
Described drawer type specimen mounting comprises the slide block that a middle part is shaped on the hole and can moves in the casing guide rail, the sample briquetting of one shape such as circular ring plate, an and sample holder, this sample holder top is shaped on the circular groove that adapts with described sample briquetting cylindrical, the groove center is shaped on and the identical through hole of sample briquetting center pit, and the bottom of sample holder is shaped on the convex that the hole with described slide block middle part adapts.
In the periphery cell wall of the circular groove in the described sample holder, there is one section cell wall to be clipped, makes cell wall constitute incomplete circle.
The specimen mounting that the utility model adopted, utilize the natural gravity of sample briquetting tested surface to be anticipated the groove that is arranged in sample holder, not only in when test owing to kept the state of nature of tested lining, can record the real anti-ultraviolet property of tested lining, also simplified the mode of locating tested lining, add that specimen mounting can level pull out and shift-in as drawer, bring great convenience to test job.In addition, because of spare and accessory parts are homemade, the cost of this machine is also lower.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 be among Fig. 1 the drawer type specimen mounting face enlarged drawing.
Fig. 3 is the mutual relationship synoptic diagram of sample briquetting, sample holder and tested textile.
Fig. 4 is the vertical view of drawer type specimen mounting.
Embodiment
As shown in Figure 1, this antiultraviolet tester has an airtight casing 7 (clear for drawing, casing is represented with dot-and-dash line), and integrating sphere 4 is housed in the casing, and integrating sphere vertically up is optical filter 2 and ultraviolet source 1 successively.Ultraviolet source commonly used is xenon lamp and deuterium lamp, and the utility model adopts deuterium lamp.But between integrating sphere and the optical filter specimen mounting 3 that level moves into and pulls out, integrating sphere divides the two-way output signal, one the tunnel through reference detector 11, amplifying circuit 9-2 and photoelectric commutator 8-2 input microcomputer, another road is through beam splitting system 5, signal sensor 10, amplifying circuit 9-1 and photoelectric commutator 8-1 input microcomputer, and two paths of signals machine as calculated promptly obtains all kinds of parameters of tested textile after handling.The collection of Various types of data, demonstration, automatic control etc. realize by microcomputer software.
Generally speaking, the shape made as Fig. 2 and the described slide block 3-4 of Fig. 4 of described drawer type specimen mounting gets final product.This slide block middle part is shaped on the hole and can slides in casing guide rail 12, and tested textile is placed on the hole and just can tests.
For improving the test effect, the drawer type specimen mounting structure that the utility model provides can be from Fig. 2, Fig. 3 and Fig. 4 as can be known, described drawer type specimen mounting comprises the slide block 3-4 that a middle part is shaped on the hole and can slides in casing guide rail 12, the sample briquetting 3-1 of one shape such as circular ring plate, an and sample holder 3-3, this sample holder top is shaped on round groove, and the bottom land of this groove is the plane, and circumferentially cell wall constitutes a periphery.Described sample briquetting can fall into this groove; The groove center is shaped on and the identical through hole of sample briquetting center pit, and ultraviolet light can pass from this through hole; The bottom of sample holder is shaped on convex, and locate in the hole that can fall into described slide block middle part.
During test, tested textile 3-2 is cut into the shape that is slightly less than the sample briquetting, is positioned in the groove of sample holder, covers with the sample briquetting again, slide block is passed entered the measured position then.This kind can keep the state of nature of tested textile by the mode of the tested textile of sample briquetting gravitational orientation, thereby can record real data.
In the circular groove among the described sample holder 3-3, there is one section cell wall to be clipped, make cell wall become incomplete circle, so one section of sample briquetting 3-1 can protrude on the sample holder, takes the sample briquetting and tested textile seems particularly convenient from sample holder during operation.
Above-described deuterium lamp, integrating sphere, reference detector, amplifying circuit, photoelectric commutator, microcomputer and power supply etc. all are commercially available.
The utility model can detect ultraviolet ray transmissivity, UPF and the ultraviolet penetrance of textile effectively.
