Wherein, one end of the transition groove 11 is connected with the bag storage groove 10, and the other end is butted with the guide groove 12. The positioning assembly comprises a filling positioning assembly 18, and due to different sizes of the packaging bags, the width of the bag storage groove 10 and the width of the guide groove 12 can be set to be different by setting the adjusting assembly so as to adapt to the requirements of the packaging bags with various sizes. The filling positioning assembly 18 comprises a filling positioning member 181 and a filling positioning lifting mechanism 182, the filling positioning lifting mechanism 182 drives the filling positioning member 181 to move from a first position of a packaging bag which slides down from the receiving guide slot 12 to a second position where the bag opening assembly 15 and the filling assembly 16 respectively open and fill the packaging bag, so that the filling positioning member 181 can timely receive the packaging bag which basically slides from the transition slot 11 to the guide slot 12, the speed of the packaging bag is low, the deformation of the packaging bag when the packaging bag contacts the filling positioning member 181 is low, therefore, the packaging machine can be ensured to normally fill the packaging bag with the materials to be filled, and the filling qualification rate is high.
