The invention provides a saggar material mixing device, and belongs to the technical field of supporting facilities of an electronic kiln. The saggar material mixing device comprises a rack, a saggar jacking and vibrating mechanism, a pair of saggar material shaking and mixing mechanisms, a pair of saggar centering mechanisms, a saggar material even-distribution mechanism, a saggar position signal collector and a saggar stopping mechanism, wherein the saggar jacking and vibrating mechanism is arranged on the lower portion of the rack, the saggar material shaking and mixing mechanisms are arranged on the saggar jacking and vibrating mechanism, the saggar centering mechanisms are arranged on the two sides of the rack, the saggar material even-distribution mechanism is arranged on the upper portion of the rack and corresponds to the position above the saggar jacking and vibrating mechanism, the saggar position signal collector is also arranged on the rack and corresponds to the left side of one of the saggar centering mechanisms, the saggar stopping mechanism is also arranged on the rack and corresponds to the left side of the saggar position signal collector, and a cross-shaped positional relation is formed by the pair of saggar centering mechanisms and the pair of saggar material shaking and mixing mechanisms. The saggar material mixing device enables the work intensity to be reduced for workers beneficially, and is high in efficiency, capable of being matched with the saggar drawing speed of the electronic kiln, and excellent in shaking and mixing effect, thereby ensuring firing quality.
