In the quilt line, an air pressure hopper is a necessary device which is connected in front of the cotton feeding device (usually a condenser) and in back of the carding machine. The gin delivers clean, fully opened cotton fibers (usually by wind) to an air pressure hopper, which initially shapes the cotton fibers, delivers (usually by a transfer wheel) a cotton layer of a given width and thickness to a carding machine, which further processes the cotton layer. The cotton fiber of cotton machine output that congeals is filiform or flocculent solid, is difficult to carry out the close control to the delivery capacity, and the volume of the cotton fiber who arrives in the atmospheric pressure hopper in the same time is different because of wind-force and the difference of cotton fiber motion, so can lead to the cotton layer of atmospheric pressure hopper output unstable (too fluffy or too closely knit) to influence the quality of carding machine comb cotton, finally influence the quality of cotton quilt.

Some inventors have proposed some solutions to the above-mentioned problem, for example, the utility model patent with the name "automatically micro-adjusting air pressure hopper" disclosed in publication No. CN204530065U, which includes a cotton feeding fan, an air pressure hopper and a cotton conveying duct connected to the air pressure hopper and having a fine adjustment part, the fine adjustment part can extend or contract according to the air pressure fluctuation in the duct, so as to buffer the change of the air pressure in the duct, so as to improve the stability of the air pressure hopper for supplying cotton. However, the utility model discloses a exist certainly not enough, it has only solved wind-force fluctuation to a certain extent and has supplied cotton to supply cotton influence of cotton to the atmospheric pressure hopper, and to supplying cotton quality problem unable reply to the atmospheric pressure hopper that causes because of cotton fiber movement, if during the partial adhesion gathering of cotton fiber, the local too fluffy or closely knit condition can appear in the cotton layer that the atmospheric pressure hopper provided.
