Abstract

The invention discloses a sample preparation device capable of preventing sample residues. The device comprises a cabinet body; a blanking hopper for feeding is arranged at the top of the cabinet body; the cabinet body is internally provided with a rolling shear mechanism for shearing samples; and a movable receiving hopper is arranged below the rolling shear mechanism. The rolling shear mechanism comprises a pair of knife rollers provided with round blades, a knife comb is correspondingly arranged at the position, located at a shear opening, of each knife roller, and shaking protruding points which can make contact with the corresponding knife comb during rotation of the knife rollers and enable the knife comb to vibrate alternately are arranged on each knife roller. According to the invention, uniform sample preparation can be ensured, subsequent samples cannot be polluted, the labor intensity of detection personnel is reduced, and the consistency and the detection efficiency of the samples are improved.

Description

technical field [0001] The invention relates to the technical field of substance quality detection, in particular to a sample preparation device for preventing sample residue. Background technique [0002] With the improvement of living standards, people are paying more and more attention to whether the clothes they wear affect our health, especially for infants and young children. Therefore, in the process of continuous revision of the standards, more and more detections of limited substances are involved. Generally speaking, the limited substance testing items for clothing materials such as textiles, leather and artificial leather include decomposable aromatic amine dyes (daily called banned azo dyes), disperse dyes, formaldehyde, pH value, chlorinated phenols, organic chlorine, hexavalent chromium , plasticizers such as phthalates, APEO, PFOS, volatile compound release and heavy metals, etc. There is a sample preparation link in the detection of limited substances in ch...
