The invention relates to the field of material weighing control, in particular to a food packaging production system with an accurate quantification function for small bagged bulk food. The system comprises a feeding mechanism, an accelerating mechanism, a machine frame, a rotating disc and a discharging mechanism; the feeding mechanism comprises a processing table and a feeding hopper positionedon the processing table, the feeding hopper communicates with an inclined downward pipeline, and the pipeline is gradually narrowed in the direction away from the feeding hopper; the accelerating mechanism is located at the pipe orifice, far away from the feeding hopper, of the pipeline, the accelerating mechanism comprises a plurality of parallel rollers, the rollers are rotationally connected tothe processing table, and the rollers are externally connected with a rotating motor; the rotating disc comprises a disc, a plurality of vertically-arranged separating plates are arranged at the bottom of the disc, the separating plates are distributed in a radial shape by taking the circle center of the disc as the center, the pipe orifice of the pipeline faces the separating plates of the rotating disc in the eccentric direction, and the top of the disc is rotationally connected to the machine frame. The invention aims to provide the food packaging production system which can be used for automatically and accurately quantifying the small bagged bulk food.
