A driving roller of the first conveying belt 31 is in meshing transmission with a first driving mechanism 24 through a gear set, and the first driving mechanism 24 is a cam divider; the gear set comprises a first bevel gear sleeved at the end part of the driving roller of the first conveying belt 31 and a second bevel gear sleeved at the cam divider and driven to rotate by the cam divider, and the first bevel gear is meshed with the second bevel gear. The workbench 35 is further provided with a material pushing plate 34 for pushing and packing, and the material pushing plate 34 is driven by a linear motor fixed on the frame 4.

For example, in the case of packing the first food packing box, the second conveying belt 32 first conveys the first outer box flowing in to the workbench 35, and then the second outer packing box flows in the second conveying belt 32 and forms a limit for the first outer box; then the first feeding inner box (box for containing materials) is intermittently conveyed to the outer packing box on the workbench 35 by the first conveying belt 31 through the cam cutter transmission system, and in the process, the outer packing box is placed in the automatic bagged food packing device 3 to drop the packed food packing bags into the inner box one by one and is matched with the intermittent transmission of the first conveying belt 31 for packing, so that the function of automatically arranging and packing the finished food packing bags is realized (taking 12 packing bags/boxes as an example, a 12-equal-part cam cutter is selected); and finally, when the packaging box filled with the food packaging bags completely enters the inside of the packaging outer box, the first food packaging box finished product is finished, the electric push rod acts at the moment, the first packaging box is pushed out of the outer row stacking area of the middle connecting bearing plate by the material pushing plate 34, then the next packaging action is carried out after resetting, and the automatic packaging and arranging stacking functions of the food packaging bags can be realized by continuously carrying out the next packaging action according to the action. When the electric push rod contracts, the material pushing plate 34 is flush with one of the baffle plates 33, and the entering of the subsequent packing box is not influenced.

As shown in fig. 17 to 18, since the packaging bag may fall down when falling down into the packaging box during the actual packing and packing, another embodiment is provided in which a pair of ribs 312 are provided on the driven shaft 311 of the first conveyor belt 31 in the axial direction of the driven shaft 311, and the preferable ribs 312 are divided into an upper rib and a lower rib, and the upper rib and the lower rib are symmetrically arranged on the surface of the driven shaft 311 with the axial line of the driven shaft 311 as a symmetry axis.

When the food packaging bags vertically fall, the raised strips 312 on the driven shaft 311 enable the belt to be in a raised state, and the built-in box is in an inclined state (the front part is low and the rear part is high), so that the previous packaging bag is ensured to fall into the built-in box and topple over in the feeding direction, and the boxing action of the next packaging bag is not influenced; when the conveying belt feeds a station, the driven convex shaft enables the protrusions of the belt to be gradually converted into translation, so that the boxing action of the inner boxing box into the outer boxing box is not influenced; and when the next inner packing box is conveyed into the belt through the connection mechanism, the belt is also in a horizontal state, so that the functional connection between the mechanisms is not influenced, and the automatic packing process of the food packing bags can be smoothly realized.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
