Environmentally friendly sample dyeing instrument without heat-conducting medium

Abstract

The invention provides an environment-friendly heat conducting medium-free specimen stainer. The environment-friendly heat conducting medium-free specimen stainer comprises a rotating rack, a rotating rack driving mechanism, a heating device and dye cups; a plurality of mounting holes are formed in the peripheral surface of the rotating rack at intervals; a thermal insulating sleeve is arranged at each mounting hole and one end of the thermal insulating sleeve extends into the rotating rack; each dye cup sleeves the corresponding thermal insulating sleeve and the lower part of the dye cup extends out of the bottom of the thermal insulating sleeve; the heating device comprises heating elements which are arranged beside the middle parts of the sidewalls, extending out of the bottoms of the thermal insulating sleeves, of the dye cups; the parts, extending out of the bottoms of the thermal insulating sleeves, of the dye cups rotae along with the rotating rack and are directly heated by the heating elements. The stainer of such a structure has the advantages that the outer side walls, not covered with the thermal insulating sleeves, of the dye cups are directly heated by the heating elements, and the heating efficiency is high without heating lag time difference, the thermal insulating sleeves are used for preserving heat for the outer sidewalls of one parts of the dye cups and guaranteeing that the dye cups can be continuously heated even after leaving the heaving elements, and moreover, the dye cups in a midway into-cup test also can be preheated to prevent adverse effect on the cloth specimen due to temperature deviation resulting from too slow instantaneous heating on the dye.

Description

technical field [0001] The invention relates to the technical field of dyeing, in particular to a sample dyeing instrument which can directly heat a dyeing cup without a heat-conducting medium. Background technique [0002] The dyeing machine is the testing machine that is most needed in the dyeing process. It is generally used for high-temperature dyeing. It has the advantages of rapid testing of small samples, coordination with large-scale production, separate pick-and-place dyeing cups, and convenient operation. Existing dyeing instruments include a box body, a rotating disk located in the box and several dyeing cups. The rotating disk is connected to a transmission mechanism. The transmission mechanism includes a fixed shaft and a rotating shaft sleeved on the fixed shaft. The rotating disk is filled with There is heat-conducting oil, and heating elements are arranged in the heat-conducting oil, and the heating elements are fixedly connected to the fixed shaft. It also i...
