Abstract
The invention discloses a bast fiber separating device, which comprises grinding rollers and kneading rollers positioned behind the grinding rollers. The outer diameter of each grinding roller is equal to that of each kneading roller, the grinding rollers and the kneading rollers are respectively vertically aligned pairwise, and the rollers in each pair are the same in structure and are engaged with each other. Semicircular grid bars on the surfaces of the grinding rollers are used for evenly grinding sticks of hemp stems, so that the sticks are primarily separated from bast fibers. Spirally arranged racks on the surfaces of the kneading rollers are used for kneading while further grinding the hemp stems, so that the bast fibers are thoroughly separated from the sticks. As the kneading rollers and the grinding rollers have linear speed difference, both longitudinal acting force and transverse acting force are applied to the hemp stems, and skins and the sticks of the hemp stems are separated more evenly while the bast fibers are not damaged. In addition, gaps among the semicircular grid bars and gaps among the flat racks are all arc grooves, namely contact surfaces of the hemp stems and each pair of kneading rollers are smooth arc surfaces, the strength of the bast fibers cannot be reduced, and the bast fibers cannot be lost.
