Specifically, the upper ends 2611 of the two opening and closing members 261 are respectively slidably abutted against the machine table 10, and the two opening and closing members can be abutted to form a supporting platform to support or release the small-sized food in the material cylinder 21 at the first penetrating hole 11 from the bottom, the lower ends 2612 of the two opening and closing members 261 are both arc-shaped, and the two lower ends 2612 are symmetrically arranged at the central positions of the bottom edges of the opposite ends of the two upper ends 2611, so that the two opening and closing members can be conveniently inserted into the bag opening of the packaging bag 200 to stretch the bag opening from inside to outside for fixing. Wherein the lower end 2612 is relatively wide at an upper end and relatively narrow at a lower end to facilitate insertion into a pocket opening. In addition, the lower end part 2612 can be formed by extending downwards and outwards from the central position of the bottom edge of the upper end part 2611, so that the structure is simpler, and the manufacturing cost is effectively reduced.

The pushing pipe 273 can be used for pushing small-bag food in the charging barrel 21, and can also play a role in accelerating discharging, and particularly when the blockage happens occasionally, the pushing pipe 273 can be quickly dredged through pushing, so that the blanking is facilitated. The structure and control principle of the micro air pump 274 are well known in the art, and the micro air pump can be accommodated in the pushing pipe 273 to perform the air blowing function, so that the detailed description thereof is omitted here.

In addition, in some embodiments, the centers of the opposite ends of the upper ends 2611 of the two opening and closing members 261 are recessed in the direction away from each other, so that an air supply channel is formed between the two opening and closing members 261, and when the bagging mechanism 40 transfers the packaging bag 200 with the initially opened bag mouth to the lower side of the first penetration hole 11, the micro air pump 274 can blow air into the bag mouth to open the packaging bag 200 to a larger size, and then the two opening and closing members 261 move back to support and discharge the bag mouth, thereby further improving the smoothness of dropping of the small bag food, and further improving the bagging efficiency.
