Closed five-face screen roller tobacco stalk separator

Abstract

The invention provides a closed five-face screen roller tobacco stalk separator. The closed five-face screen roller tobacco stalk separator comprises a frame, a housing, a screen roller, a feeding device, a discharging device, a long stalk ratio adjusting mechanism and a power mechanism, wherein the screen roll is fixed on a screen roller frame by a multi-section screen mesh plate and forms a five-face cylinder body; a screen roller shaft is arranged on a longitudinal central line of the screen roller; two ends of the shaft are rotationally mounted on the frame and have inclined angles of 4-6degrees with the horizontal plane; and a material storage bin corresponding to the multi-section screen mesh plate and consisting of a long stalk bin, a thick and short stalk bin, a thin and short stalk bin, a powder and toothpick stalk bin and a stalk turning bin is arranged at the lower part of the housing. The re-dried tobacco stalks are separated into preset groups of products with preset specifications by using a single machine at one time; the closed five-face screen roller tobacco stalk separator provided by the invention has the advantages of long tobacco stalk screening and time, uneasiness for unplugging screen hole, stable quality, obvious energy conservation, no vibration or friction in transmission and low noise; the yield of long stalk products is increased; the long stalk ratio is properly adjusted; and the maintenance cost and labor are effectively reduced. The tobacco stalks are screened within a relative sealed container with negative pressure to realize clean production.

Description

technical field [0001] The invention relates to a closed five-sided sieve rolling tobacco stem sorting machine. Background technique [0002] At present, most tobacco leaf redrying enterprises still use multi-stage (2-3) shrapnel-type vibrating screen screening process to process the redried tobacco stems to separate long stems, short stems and tobacco corners. At least two or more belt conveyors and other equipment are required. The main problems in this traditional tobacco stem production process are: (1) energy consumption is as high as 20kw or more (average 4 units × 5.5kw); (2) the screen surface is easily blocked, resulting in unstable quality of long stems, and the sorting cannot meet the specification requirements; (3) open-loop The vibrating screening process leads to a large amount of smoke and dust on the production site, and the environment and equipment in the production site are seriously polluted by accumulated dust and are not easy to clean; the vibrating sc...
