Problems solved by technology

Relevant quality supervision and inspection departments use the method of scraping the surface coating of the sample to detect harmful substances. However, the sampling method of the existing sample surface coating is generally adopted by the blade sampling method. Because the blade is sharp, it is very easy to cause direct damage to the operator. harm
In addition, the method of scraping the coating by blades does not fully collect the coating samples, the work efficiency is low, and the sampling is uneven

Abstract

The invention provides a sample surface coating sampling device. A scraper is driven by a motor to scrape a coating for sampling. The coating sample leaks into a sample storage bottle, so that the effects of effectively scraping and fully collecting the coating sample are achieved. The harm to an operator is avoided. A sliding block, a sliding rod, a second threaded rod and a second rotating wheelare arranged. The second threaded rod is used for pushing the sliding block to slowly move. The moving distance of the scraper can be effectively controlled, and the effect of effectively controllingthe coating scraping thickness is achieved. By arranging a lug plate, a threaded pipe, a first rotating wheel, a first threaded rod and a clamping plate, the position of the sample is flexibly adjusted. The scraper is enabled to sample a plurality of parts of the sample, and the effect of multi-position sampling is achieved.

Description

technical field [0001] The invention relates to the technical field of surface detection, in particular to a sample surface coating sampling device. Background technique [0002] At present, various new coatings are widely used in the fields of automobile industry, coatings, plastics, leather, ink printing, ceramics and cosmetics, toys, rubber, decorations and so on. Among them, cosmetics, toys, decorations and other items are in direct contact with the skin, and whether there are harmful substances in the surface coating will cause harm to human health. Therefore, it is most important to restrict the migration of specific elements on the surface coating of such items. Common requirements of national and regional safety standards. Relevant quality supervision and inspection departments use the method of scraping the surface coating of the sample to detect harmful substances. However, the sampling method of the existing sample surface coating is generally adopted by the blad...
