Discharging packaging device

The invention discloses a discharging packaging device. The discharging packaging device comprises a rack, a weighing mechanism located on the rack, an overturning mechanism located below the weighing mechanism and used for overturning the weighing mechanism, and blocking and holding mechanisms installed on the rack. The blocking and holding mechanisms comprise connecting blocks arranged on the rear side of the rack and auxiliary air cylinders fixedly connected to the connecting blocks. Output shafts of the auxiliary air cylinders extend forwards to be connected with first swing arms. An angle is formed between the first swing arms and the output shafts of the auxiliary air cylinders. Bearing blocks are arranged on the parts, in front of the first swing arms, of the rack. Bearings are arranged in the bearing blocks. Arm shafts penetrate the bearings. The front ends of the first swing arms and one ends of the arm shafts are fixedly connected, and the other ends of the arm shafts are fixedly connected with second swing arms. The second swing arms extend forwards, and baffles are arranged at the front ends of the second swing arms. By means of the reasonable overturning mechanism and the blocking and holding mechanisms, openings of package boxes can be expanded outwards through the blocking and holding mechanisms, and qualified products can smoothly slip into the package boxes.
