The fixed end of the three-axis cylinder is connected to the cylinder mounting plate 500, and the telescopic end of the three-axis cylinder is connected to the cylinder end plate 600. The three-axis cylinder drives the cylinder end plate 600 to move up and down relative to the cylinder mounting plate 500. When in use, the height of the cylinder mounting plate 500 can be adjusted by loosening the handle and turning the hand wheel, thereby adjusting the working height of the cylinder end plate 600 to achieve the function of adapting to cartons with a height within a certain range. After the height adjustment is completed, the working height can be positioned by locking the handle.

[0049] Specifically, the third opening assembly 700 is fixed to the bottom of the cylinder end plate 600 through a fixed profile; the third driving member and the third suction cup group are respectively arranged at opposite ends of the fixed profile; the third suction cup group includes a suction cup seat 121 and a buffer suction cup 122, and a plurality of the buffer suction cups 122 are fixed to the suction cup seat 121, and the buffer suction cups 122 are responsible for providing suction for the upper flip cover to flip upward. The third suction cup group is connected to the third driving member through a curved rod, which is L-shaped, one end of the curved rod is fixed to the suction cup seat 121, and the other end is connected to the first driving member 110, and the bent portion formed in the middle is hinged to the end of the fixed profile through a hinge; the third driving member of this embodiment is a cylinder, having a fixed end and a telescopic end, the fixed end of the third driving member is connected and fixed to the fixed profile through the cylinder seat 330, and the telescopic end of the third driving member is hinged to the end of the curved rod; the third driving member provides power to drive the curved rod to rotate, thereby driving the third suction cup group to rotate relative to the cylinder end plate 600, and the carton flip cover is sucked and flipped open.

[0050] The third page opening component 700 and the fourth page opening component 800 have the same structure and are arranged relative to each other, which will not be described in detail here and can be understood by those skilled in the art.

[0051] When the bottom roller conveying component of the automatic carton opener for cigarettes delivers the carton to the opening station in the carton channel, the carton passes through the in-place detection arranged on the frame component of the automatic carton opener to sense the carton, and then controls the first driving member 110, the second driving member 210, the third driving member and the fourth driving member to extend quickly, and the connecting rod 125 cooperates with the hinge to make the first suction cup group 120, the second suction cup group 220, the third suction cup group and the fourth suction cup group quickly approach the flaps of the carton, and after the buffer suction cups 122 on each suction cup group adsorb the carton flap, each flip cylinder retracts to drive the carton flap to open, and then the bottom roller conveying component of the automatic carton opener for cigarettes transports the carton through the guiding effect of the cover opening guide rod of the frame component, and folds the carton flap to achieve the purpose of flipping and opening the carton.
