Fuente: WIPO "hemp" The utility model provides a fiber mixing device for linen-cotton colored spun yarns, which is characterized in that a mixing box is cylindrical, extends in the left-right direction and can be axially and rotatably mounted on a base, and a feeding hole is formed in the mixing box; the stirring shaft is coaxial with the mixing box and can be axially and rotatably mounted on the base, and a stirring blade is arranged in the middle of the stirring shaft, is positioned in the mixing box and is connected with the mixing box through a sealing bearing; the first driving mechanism drives the mixing box to axially rotate; and the second driving mechanism drives the stirring shaft to axially rotate. The technical scheme provided by the utility model has the beneficial effects that the rotation of the stirring shaft and the rotation of the mixing box can promote the mixing of jute fibers and cotton fibers, and simultaneously avoid that the jute fibers and the cotton fibers at the bottom of the mixing box cannot be stirred, so that the jute fibers and the cotton fibers are uniformly mixed, manual mixing is replaced, and the mixing efficiency of the jute fibers and the cotton fibers is improved; the hemp cotton fibers are limited in the mixing box and are prevented from flying into the air to influence the environment.
