Description

Technical Field

[0001] The utility model belongs to the technical field of down detection, and in particular relates to a down collecting device for detecting residual fat rate of down. Background Art

[0002] In the testing of down and down products, the residual fat rate of down is an important item for assessing the quality of down. When the residual fat rate of down is measured in accordance with GB / T10288 "Test Methods for Down and Feather" or GB / T 14272 "Down Clothing", two down samples that have been dried to constant weight need to be placed in two filter paper cylinders, and then the filter paper cylinders are placed in two extractors for extraction experiments. In the actual operation process, the experimenter first manually wraps the filter paper to make a filter paper cylinder, then fills the down sample into the filter paper cylinder, and then places the filter paper cylinder containing the down sample in the extractor for extraction experiments. In the process of stuffing the down sample into the filter paper tube, or in the process of placing the filter paper tube into the extractor for extraction experiment, sample leakage often occurs due to loose wrapping of the filter paper tube, resulting in failure of the experiment. In addition, in the process of stuffing the sample into the filter paper tube, it is difficult to avoid sample spillage due to manual stuffing, and the down sample is very light, and the spilled sample can easily float in the air, which not only pollutes the laboratory environment, but also causes serious harm to the body after being inhaled by the experimenters.
