[0027] Working principle:

[0028] When in use, first place the carton body 5 on the top surface of the conveyor belt 4, and the conveyor belt 4 starts working to convey the carton body 5 to the specified position. In this process, two limit plates 11 limit the two sides of the carton body 5 to ensure the stability of the carton body 5 during the conveying process. The position of the limit plate 11 can be adjusted by the motor 10 driving the threaded rod 8. Because the connecting block 9 is connected to the two sections of the threaded rod 8 with opposite rotation directions, when the motor 10 is working, the two connecting blocks 9 will move relative to each other, thereby driving the limit plate 11 to move to adapt to cartons of different sizes. After the carton body 5 is conveyed to the specified position, the two groups of pressing pieces start working, and one group of pressing pieces is mainly used to press the opening of the carton body 5 so that the opening The surface of the carton is smoother and more convenient for subsequent gluing work. The other set of pressing parts is used to smooth the adhesive after gluing to ensure that the adhesive is evenly distributed at the opening of the carton. The two sets of pressing parts drive the slider 21 and the pressure plate 22 to extend and retract through the electric push rod 23 to achieve pressing and smoothing of the carton. While the pressing parts are working, the gluing components also start working. The sensor 17 will sense the position of the carton body 5, and then start the pressure pump 14 to press the adhesive in the adhesive storage box 13 into the nozzle 16 through the hose 15. The nozzle 16 applies glue to the opening of the carton. The observation port 24 on the adhesive storage box 13 allows the staff to observe the remaining amount of adhesive. When the adhesive is insufficient, adhesive can be added through the injection port and sealed with a rubber plug 25.
