Description

Technical Field

[0001] This utility model relates to the field of textile testing technology, specifically to a device for detecting the heavy metal content in textiles. Background Technology

[0002] Metals refer to metals with a density greater than 4.5 g / cm³, including gold, silver, copper, iron, mercury, lead, cadmium, etc. Heavy metals are very difficult to biodegrade; on the contrary, they can accumulate thousands of times through biomagnification in the food chain, eventually entering the human body. In the human body, heavy metals can interact strongly with proteins and enzymes, rendering them inactive, and may also accumulate in certain organs, causing chronic poisoning.

[0003] The reference patent number is "CN218239890U", entitled "A Device for Detecting Heavy Metal Content in Textiles". Although this application solves the problem that "currently, some devices for detecting heavy metal content in textiles are not convenient for simultaneously detecting the front and back sides of textiles; the time spent loading and unloading textiles is long, affecting the efficiency of detection", it also has some shortcomings. For example, in the above application, the clamping spring only connects the horizontal plate and the clamping frame at the top and bottom, without setting a limiting mechanism. This can easily lead to the spring deforming after long-term use, resulting in poor positioning and clamping effect and thus affecting the detection efficiency. Moreover, the above application does not set a dust removal mechanism, which can cause dust to adhere to the textiles and easily affect the accuracy of the detection results of heavy metal content in textiles. Therefore, a device for detecting heavy metal content in textiles is proposed to solve the above-mentioned technical problems. Utility Model Content
