Double shaft gravimetric blender to prevent material stratification
Technical field
[0001] This utility model belongs to the field of gravimetric blenders, especially a dual-shaft gravimetric blender that prevents material stratification.
【Background technique】
[0002] The basic principle of the gravimetric blender: the two-speed motor transmits power to the worm in the transmission box and then transmits it to the main shaft through the worm wheel and a pair of gears and decelerates. The main shaft drives the gear to rotate synchronously, so that the mixing blade fixed on the eccentric seat revolves. At the same time, the stirring blade completes its rotation movement around the fixed internal gear through the planetary gear at the upper end of the stirring blade shaft. The two-speed motor is controlled by the time program controller to automatically complete a specified work program of slow-stop-fast rotation. The mixing pot and the sliding plate are locked by the eccentric groove rotation. The following problems have been found in the use of the entire gravimetric blender. When the density of the mixed materials differs greatly, the materials are easy to layer during the mixing process, and the light materials will agglomerate on the upper layer, resulting in uneven material dispersion and mixing.
