The invention belongs to the technical field of packing machines, and specifically relates to a filling and packing integrated machine for biscuits. The machine comprises a base, supporting legs, a supporting column, a rotating shaft, a roller, a conveyor belt, a clamping block, a belt, a motor, a fixing plate, a roller brush, a rotating rod, a feeding plate, a biscuit packing machine, a supporting plate, a storing plate, an air pump, a linear motor, a fixing block, an air pipe, a guide ring, an output rod, an electric pushing rod, a pneumatic claw, a storing barrel, a discharging pipe, a solenoid valve and a receiving plate. According to the machine, the biscuits are automatically filled, and meanwhile, the filled biscuits are automatically conveyed, so that the biscuit filling efficiencyis improved; and moreover, the filled biscuits are conveniently automatically conveyed into the biscuit packing machine, and thus the workload of a user is decreased, and the convenience of use is ensured; a cleaning mechanism is arranged and is used for cleaning impurities on the surface of the conveyor belt after conveying; and meanwhile, the cleaned impurities are discharged into the receivingplate, so that the workload of a cleaning worker is extremely reduced.
