Surface layer sampling device for uniformly scraping coating layer on surface of light industrial product

Abstract

The invention relates to a surface layer sampling device for uniformly scraping a coating layer off the surface of a light industrial product. An annular ring is arranged at the edge of an opening at the lower part of a barrel body with a downward opening, and a motor is arranged in the annular ring; a motor shell is connected with a supporting shaft; the other end of the supporting shaft extends out of a hole in a top cover of the barrel body; threads are formed on the supporting shaft part extending out of the top cover of the barrel body; a screw cap sleeves the supporting shaft part with the threads; digital scales are arranged on the outer surfaces of the screw cap and the top cover of the barrel body; a plurality of blades capable of rotating along with the motor are arranged on a rotating shaft of the motor; cutting edges of the blades are downward and are positioned on the same plane. The surface layer sampling device has the advantages that the coating layer of the surface of the light industrial product can be precisely and uniformly scraped in the thickness direction by the blades of the motor, so that scraped dust does not contain a base layer material which is not required to be scraped off.

Description

technical field [0001] The invention relates to the technology of scraping off the surface coating, in particular to a surface layer sampling device for evenly scraping off the surface coating of light industrial products. technical background [0002] With the improvement of people's living standards, the aesthetic and functional requirements of light industrial products (leather products, textiles, wood products, bamboo mat products, rubber, toys, etc.) are also getting higher and higher. Electricity, sunscreen, luminous, lubricating new coatings, paints, inks, etc. are widely used in light industrial products. Because leather products, textiles, wood products, bamboo mat products, rubber, toys and other products are often in direct contact with the skin, there are harmful substances (heavy metals, formaldehyde, volatile substances, banned azo dyes, etc.) in some surface coatings. ), will affect human health. Therefore, it is a common requirement of safety standards in ...

AI Technical Summary

Problems solved by technology

For product safety-related quality supervision and inspection departments need to scrape the coating from the surface of this light industrial product for testing, and the sampling of the existing sample surface coating is mostly people use a blade with a sharp blade to scrape the surface of the sample for sampling, often The substrate hangs down, the work efficiency is low, the sampling volume is small, and the scraped powder will fly everywhere and be inhaled by the operator, which will affect the health of the operator, and because the blade is sharp, it is also easy to cause direct injury to the staff. Time manipulation is prone to occupational diseases and is a potential killer of health

[0003] When scraping off the surface coating of light industrial products by hand, it is impossible to grasp the uniformity of the scraped coating in the thickness direction. Often the body material under the coating is scraped off together, and the surface coating and the body material are mixed together. Chemical analysis of surface coatings by scraping dust of materials, resulting in huge errors
