The utility model provides an improving wind branch efficiency and reducing the device that garrulous rate was made to the material, simple structure and wind branch efficiency and precision are high -efficient and have the low wind branch system that makes garrulous rate, simultaneously, change traditional ejection of compact form for guipure formula structure, and the installation form is vertical to the downside ejection of compact, replace material discharge device screen cylinder and realize the glassware separation, fall low -wind -resistance, improve the wind field uniformity, it makes garrulous and foldingly to utilize the filter material guipure to carry the ejection of compact effectively to reduce the tobacco leaf that the extrusion of material discharge device cross door arouses, net tape running speed is about 1.5ms, and the guipure operation sets up rectify a deviation measuring, the mechanism of rectifying a deviation, and this form can reduce the guipure rotational speed to increase ejection of compact flow, increase operational reliability, the equal blast gate door of air -out pipe setup guarantees that wind divides the wind field uniformity, does not have the bits of broken glass of making during the ejection of compact, has the function of flexible blanking. Thereby effectual improvement wind branch quality soft breeze divides efficiency, has the considerable low garrulous ejection of compact quality of making.
