The induction booster 44 includes a photoelectric sensor and an air blowing assembly. When the lunch box moves to the entrance of the slideway, the photoelectric sensor is triggered, and the photoelectric sensor After being triggered, the blowing assembly blows the lunch box into the slideway and slides down to the collection box 42 .

Before the lunch box grasping device 21 grabs the lunch box, the adsorption surface of the first adsorption plate 222 faces down, descends to the low position to absorb and pick up the packaging bag, then rises to the high position, moves horizontally to the outside of the bag storage box, and rotates 90° horizontally, Make its adsorption surface opposite to the adsorption surface of the second adsorption plate 223, and the two adsorption plates move horizontally to the adsorption surfaces to fit together. The plate 223 is moved away, and the packaging bag is opened.

Further, in order to achieve a better opening effect of the packaging bag, when the first suction plate 222 and the second suction plate 223 open the packaging bag, the lifting cylinder matched with the first bag stretching device 224 will move the first bag stretching device 224 from the high position The preparation station lowers to the lower bag-stretching station, the first bag-stretching arm 2241 and the second bag-stretching arm 2242 descend into the opening of the packaging bag, and the piston rods of the double-rod cylinder 2243 move outward to make the first bag-stretching arm 2241.

The first adsorption plate 222 and the second adsorption plate 223 move in opposite directions to fit the mouth of the packaging bag together. After the bonding, the suction port of the adsorption surface is positively pressured, and the packaging conveyor belt 303 is activated to make the packaging bag move toward the sealing machine 301 and close the mouth. The guide frame 302 ensures that the opening of the packaging bag will not be opened during the movement to the sealing machine 301, and the sealing is completed after the packaging bag runs to the sealing machine 301 for sealing.

Every time the sealed bag is full and needs to be transported to the sealing machine 301, the lunch box grabbing device 21 stops working, and the stop time is set as the feeding time of a group of lunch boxes, and the uncaught lunch boxes of this group are finally sent to the quality inspection Unit 4 triggers the photoelectric sensor when it arrives at the entrance of the slideway 41. After the photoelectric sensor is triggered, the blowing assembly blows the lunch box into the slideway and slides down into the collection box 42. The quality inspector conducts quality inspection on the lunch boxes in the collection box.
