Description

Technical Field

A fixing rod is arranged on the upper end of the equipment housing, and the entrance corresponds to the left side of the rotating disk. The fixing rod is arranged vertically downward and is arranged at the upper end of the center of the rotating disk. When the supporting rotating rod drives the rotating disk to drive the package to rotate, it can gradually approach the sorting plate until it contacts it. When the package is lighter and contacts the sorting plate, it cannot drive it to rotate and squeeze the spring, so that it directly falls down to the left side of the equipment housing under the guidance of the inclined surface of the sorting plate. When the weight of the package is heavier, the spring can be squeezed to the limit and then fall down, and stored in the middle of the equipment housing, so as to achieve the effect of avoiding the center of gravity shift.
