[0002] In the prior art, down is a mixture of "feather" and "down", and the down cluster is a three-dimensional spherical shape, which is a cluster structure composed of a down core and many down filaments radiating from the core, similar to dandelion. The down filament is composed of thousands of tiny scales, and each scale is hollow. Each down filament has many diamonds, which contain a lot of non-flowing air. At the same time, a large amount of air is also fixed between the down filaments and the down clusters. In the production process of down, different down needs to be screened, so a down screening device with separation and discharging functions is needed.
[0003] In the current down screening technology, the air selection method is widely used, but it has significant shortcomings. The down is blown up by air selection, and the flying height of the down is different according to different specific gravity to judge the quality. In theory, the higher the flying height of the down, the better the quality. However, in the actual operation process, when the high-quality down flies to the highest point, the existing device cannot timely discharge it from the discharge port. This leads to a considerable part of the high-quality down that has reached the screening height falling back to the lower part of the screening machine due to gravity, and needs to be screened again. As a result, not only the number of screening processes is increased, but also energy and time are wasted, and the screening efficiency is greatly reduced, which affects the production progress and capacity and increases the production cost.
