After the second upper slide 6 squeezes the second push rod 48, the oblique tooth plate 50 disengages from the oblique tooth groove 51, and the spring rope 45 pulls the side slide block 33 down, so that the squeezing roller 37 squeezes the sealing part of the carton 1 to make the two ends of the carton 1 stick together. After the second limit slide block 43 contacts the fourth sensor 59 for a period of time, the external controller controls the telescopic ends of the two second electric telescopic rods 9 to retract, and resets the external air pump, so that the four telescopic rods are reset, and the formed carton 1 falls out through the drop hole 7. The telescopic end of the second electric telescopic rod 9 retracts for a certain period of time and then extends again, and the motor 20 reverses to reset the mounting slide 19, and the telescopic ends of the two first electric telescopic rods 10 retract to reset the two upper slides. In this cycle, after the carton 1 to be formed is placed on the bottom slide 4, the device can automatically fold and form the carton 1, which is easy to operate.
