A down component and content detection system, and down quality detection method

Abstract

The invention discloses a down component and content detection system, which comprises a pretreatment device, a winnowing device and a collection device which are connected in sequence; The inside moves to the outside; the winnowing device includes a vertically arranged sub-screen cylinder, a static eliminator arranged at the bottom of the sub-screen cylinder, and a push plate. The side of the lower part of the sub-screen cylinder communicates with the pretreatment cylinder, and the 1. A number of outlets are arranged along its height direction, and the second air flow blows the down to a stable height in the sub-sieve cylinder; the collection device includes a collection part and an air extraction pipe connected to the outlet, and the third air flow passes from the sub-sieve cylinder along the collection part, Pumping tube movement. The invention classifies and detects the components of the down by using the weight difference between the components of the down, reduces manual screening, lightens the workload, avoids subjective influence of people, and makes the data more objective and accurate.

Description

technical field [0001] The invention relates to the detection field, in particular to a down component and content detection system and a down quality detection method. Background technique [0002] As a natural fiber, down has excellent properties such as lightness, softness, warmth, and moisture resistance. Its products have irreplaceable advantages of other products and are favored by consumers. With the development of the market economy, the import and export scale of my country's down and its products is also expanding. However, the outbreak of bird flu in the world has caused the production of down to fail to meet the market demand. Many down manufacturers have mixed down with feathers such as land poultry feathers and long feather flakes as shoddy products, which makes down and its products unqualified. phenomenon occurs in large numbers. Therefore, it is very necessary to detect the composition of down. The composition of down is an important item in GB / T 14272-20...

AI Technical Summary

Problems solved by technology

Down silk and feather silk cannot form a good polymerized and fluffy effect, and are easy to escape, which affects the appearance and thermal performance of clothes

[0004] Conventional down testing uses manual sorting. An analysis sample is placed in a sorting box, and the components are picked out with tweezers and weighed separately. Although this method is accurate, it is time-consuming and labor-intensive, and is not suitable for primary and rapid testing. detection
