Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of whiteness testing, in particular to a sample making machine for whiteness testing. Background Art
[0002] Whiteness sample making machine is a special instrument used to measure the whiteness of the surface of an object, that is, the degree to which the color of the material is close to white. This instrument usually expresses the whiteness value as the percentage of the amount of light diffusely reflected by the sample to the amount of incident light. Whiteness sample making machine is widely used in papermaking, printing, textile printing and dyeing, building materials, chemicals, grain, salt making and other industries, as well as other production and commodity inspection departments that need to measure the whiteness of objects. However, common sample making machines lack effective light-proofing measures during testing and are easily affected by external light sources. When the surface of the test sample is uneven, it is easy to cause light leakage, thereby reducing the accuracy of the test. The overall height is fixed and cannot be flexibly adjusted. If a structure with a sealing function and adjustable height without affecting its normal use is set, the accuracy and practicality of the overall test can be ensured. Therefore, a sample making machine for whiteness testing is proposed. Utility Model Content

When the surface of the test sample is uneven, it is easy to cause light leakage, thereby reducing the accuracy of the test. The overall idea is as follows:

The protective cover 6 is movably connected. When performing a whiteness test, the sample holder 5 is pressed downward, and the elastic member arranged on the lower surface of the sample holder 5 is squeezed, and the sample to be tested is placed on the sample holder 5. At this time, the sample holder 5 is reset by the elastic force of the elastic member. During the reset process, the sample on the sample holder 5 will fit with the lower surface of the detector 4, and the connecting ring 11 fixed on the surface of the sample holder 5 will be connected with the protective cover 6 slidably connected to the detector 4. The connection between the sample holder 5 and the protective cover 6 makes the test process in a closed state, which can prevent interference from external light sources.
[0024] Two card slots 10 are provided on the surface of the detector 4, and two connecting blocks 7 are fixedly connected to the inner wall of the protective cover 6. The two connecting blocks 7 are slidably connected to the two card slots 10 respectively.

The machine is started for testing through the control button on the sample making machine body 1. The overall structure provides a more stable and reliable measurement environment to ensure the accuracy of the measurement results.
[0025] The inner walls of the two strip grooves 16 are provided with strip grooves 15, and the two strip grooves 15 are respectively movably connected with the two limit bars 12. The rear surfaces of the two limit bars 12 are fixedly connected with two springs 13, and the two pairs of springs 13 are respectively fixedly connected with the two strip grooves 15.

[0026] Working principle:
[0027] When conducting a whiteness test, the sample holder 5 is pressed downward, and the elastic member provided on the lower surface of the sample holder 5 is squeezed, and the sample to be tested is placed on the sample holder 5. At this time, the sample holder 5 is reset by the elastic force of the elastic member. During the reset process, the sample on the sample holder 5 will fit with the lower surface of the detector 4, and the connecting ring 11 fixed on the surface of the sample holder 5 will be snap-connected with the protective cover 6 slidably connected to the detector 4. At this time, the machine is started for testing through the control button on the sample preparation machine body 1. The snap connection between the sample holder 5 and the protective cover 6 makes the test process in a closed state, which can prevent interference from external light sources, provide a more stable and reliable measurement environment, ensure the accuracy of the measurement results, and ensure the accuracy of the measurement results when facing different thicknesses. When the sample is of a certain height, the elastic force of the elastic part of the sample holder 5 is limited. In order to ensure that the test sample fits tightly with the detector 4, it is necessary to flexibly adjust the height of the detector 4. Pulling the handle block 14 backward will drive the two limit bars 12 fixed to it to move together, compressing the two pairs of springs 13. At this time, the two limit bars 12 will be disengaged from the two fixing bars 8 fixed on the bracket 2, and the limit is opened. The bracket 2 can drive the detector 4 to move up and down. After moving it to the required height, it is reset by the elastic force of the two pairs of springs 13, and the two limit bars 12 are clamped with the two fixing bars 8 again. The whole is in a limited fixed state, which is flexible and adjustable to meet different test requirements, thereby improving the overall practicality.
