Down feather component and content detection system, and down feather quality detection method

Abstract

The invention discloses a down feather component and content detection system which comprises a pretreatment device, an air classification device and a collecting device which are sequentially connected, wherein the pretreatment device comprises a horizontally-placed pretreatment cylinder, and first airflow moves from the interior of the pretreatment cylinder to the outside through ventilation holes; the air classification device comprises a vertically-arranged screening barrel, an electrostatic eliminator arranged at the bottom of the screening barrel and a push plate; the side face of the lower portion of the screening barrel communicates with the pretreatment barrel; a plurality of outlets are formed in the side wall of the screening barrel in the height direction of the screening barrel; down feather is blown into the screening barrel by second airflow to be stable at a certain height; the collecting device comprises a collecting part and an exhaust pipe which communicate with theoutlet; and the third airflow moves along the collecting part and the exhaust pipe in sequence from the screening drum. According to the method, the down feather components are classified and detectedaccording to the weight difference between the down feather components, manual screening is reduced, the workload is reduced, the subjective influence of people is avoided, and data is more objectiveand 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
