When the translation assembly approaches the rotating seat 312, the first inner support plate 321 and the second inner support plate 322 approach each other so that both extend into the packaging bag at the same time. At the same time, the upper suction cup 234 and the lower suction cup 235 remove the force on the packaging bag, and then the first inner support plate 321 and the second inner support plate 322 move away from each other to open the packaging bag. The rotating motor 311 can control the rotating seat 312 to rotate so as to change the position of the inner support assembly 32 with the packaging bag, realize switching, and facilitate the bread to enter the packaging bag and subsequent sealing.

[0048] The implementation principle of a bread packaging machine in the embodiment of the present application is as follows: when bread needs to be packaged, the staff puts the bread on the conveyor belt 12 for transportation, and the empty packaging bags are stacked on the bag storage box 21. Then the bag taking component 22 takes out the packaging bag at the bottom of the bag storage box 21, and then the bag opening component 23 opens the opening of the taken out packaging bag.

[0049] As the bag opening assembly 23 moves horizontally, the opened packaging bag is transferred to the inner support assembly 32. The inner support assembly 32 opens the packaging bag so that bread can be put in. The rotating assembly 31 controls the inner support assembly 32 to rotate. When the inner support assembly 32 rotates to the lowest position, the driving member 41 controls the push rod 42 to push the bread on the conveying assembly 1 into the opened packaging bag. At the same time, the desiccant on the coil 51 is cut into a bag by the cutting member 52. The desiccant gradually approaches the push rod 42 along the unloading track 53 and flies into the opened packaging bag under the action of inertia, thereby bagging the bread and the desiccant together.

[0050] After pushing the bread into the packaging bag, the push rod 42 continues to move, so that the packaging bag containing the bread and the desiccant is separated from the inner support component 32, and finally the opening of the packaging bag is heat-sealed by the heat-sealing component 6 to realize automated production.
