Description

[0001] The utility model belongs to the field of textiles, and particularly relates to a device for detecting heavy metal content in textiles. Background Technique

[0002] With the development of the textile industry, the problem of heavy metal content in textiles has attracted increasing attention. Heavy metals not only pollute the environment but also pose a threat to human health. Therefore, the detection of heavy metal content in textiles has become particularly important. Currently, there are various textile heavy metal detection devices on the market. These devices mostly adopt advanced analysis techniques, such as atomic absorption spectrometry, inductively coupled plasma mass spectrometry, etc., and can accurately detect the heavy metal content in textiles;

[0003] Existing textile heavy metal detection devices generally have fixed detection probes and sample tables, and textiles need to be kept flat during the detection process. However, due to the softness and easy bendability of textiles, samples are prone to bending and deformation during the detection process, resulting in the detection probe being unable to comprehensively and accurately detect the textiles, thereby affecting the accuracy of the detection results. The probes are mostly fixed and cannot be flexibly adjusted in position, which has certain limitations for the comprehensive detection of textiles. Therefore, a device for detecting heavy metal content in textiles is designed to overcome the above technical defects. Content of the Utility Model

[0039] A longitudinal sliding groove is provided inside the transverse support column 5. The longitudinal moving block 15 is located inside the longitudinal sliding groove and is slidably connected to the transverse support column 5 through the longitudinal sliding groove. Through the arrangement of the longitudinal sliding groove, the longitudinal moving block 15 can slide longitudinally inside the transverse support column 5;

[0040] Here, the operation of the double-output shaft cylinder 20 enables the transverse displacement block 21 to move. The movement of the transverse displacement block 21 enables the vertical displacement block 23 to move vertically through the oblique rotating column 22. The lifting of the vertical displacement block 23 enables the transverse support column 5 to lift, and further enables the distance between the X-ray fluorescence spectrometer 6 and the textile to be adjusted. Through the operation of the third driving motor 25, the longitudinal threaded rod 26 can rotate.

[0041] Working principle: When using the detection device of this technical solution, the operation of the second drive motor 11 enables the first horizontal threaded rod 12 and the second horizontal threaded rod 13 to rotate. The rotation of the first horizontal threaded rod 12 and the second horizontal threaded rod 13 enables the horizontal moving block 14 to slide horizontally inside the rectangular box 1, and further enables the moving directions of the two horizontal moving blocks 14 to be opposite. The movement of the horizontal moving block 14 enables the longitudinal rotating column 19 to rotate through the first inclined transmission rod 16 and the second inclined transmission rod 17. The rotation of the longitudinal rotating column 19 enables the third inclined transmission rod 18 to rotate, and further enables the guiding roller 9 to rotate around the longitudinal rotating column 19, thereby being able to adjust the tension of the fabric and prevent the fabric from bending during detection, which affects the detection quality;

[0042] The operation of the double-output shaft cylinder 20 enables the horizontal displacement block 21 to move. The movement of the horizontal displacement block 21 enables the vertical displacement block 23 to move vertically through the inclined rotating column 22. The lifting of the vertical displacement block 23 enables the horizontal support column 5 to move up and down, and further enables the distance between the X-ray fluorescence spectrometer 6 and the fabric to be adjusted. Through the operation of the third drive motor 25, the longitudinal threaded rod 26 can rotate. The rotation of the longitudinal threaded rod 26 enables the longitudinal moving block 15 to move inside the horizontal support column 5, and further enables the longitudinal position of the X-ray fluorescence spectrometer 6 to be adjusted, so that the X-ray fluorescence spectrometer 6 can detect the fabric more comprehensively, and enables the two X-ray fluorescence spectrometers 6 to detect the top and bottom of the fabric.
