A plurality of vacuum suction cups 25 are mounted on the upper swing rod 24. When the swing cylinder Ⅲ23 drives the upper swing rod 24 to swing to the lowest end, the vacuum suction cups 25 adsorb and fix the outer surface of the upper cover. After the vacuum suction cups 25 adsorb the upper cover, the swing cylinder Ⅲ23 rotates in the opposite direction, so that the upper swing rod 24 drives the upper cover to flip upward, realizing the flip opening of the upper cover.

[0045] As attached Figure 2As shown, the side box cover opening mechanism includes a swing cylinder I16 and a swing cylinder II17 respectively arranged on the left and right sides of the longitudinal slide seat I5, a side swing rod I18 arranged vertically and connected to the output shaft of the swing cylinder I16, and a side swing rod II22 arranged vertically and connected to the output shaft of the swing cylinder II17. A plurality of vacuum suction cups 25 are respectively arranged on the side swing rod I18 and the side swing rod II22. When the swing cylinder I16 and the swing cylinder II17 drive the side swing rod I18 and the side swing rod II22 to swing to the innermost end, the vacuum suction cup 25 adsorbs and fixes the outer surface of the side box cover on the same side. When the vacuum suction cup 25 adsorbs the side box cover, the swing cylinder I16 and the swing cylinder II17 rotate in the opposite direction, so that the side swing rod I18 and the side swing rod II22 are respectively turned outward to open, so that the side swing rod I18 and the side swing rod II22 turn the side box covers on both sides outward, and the side box covers are turned over and opened.

[0046] As attached Figure 8 As shown, the spacing adjustment mechanism I includes a gear II 39 rotatably mounted on the driving motor and two slide bars II 41 respectively arranged at the left and right ends of the gear II 39 and horizontally inserted in the slide seat II 40. The slide seat II 40 is mounted on the lower lower seat 33. The two slide bars II 41 are respectively connected to a longitudinal slide seat II 27. The slide bar II 41 is provided with a rack along its length direction. The two slide bars II 41 are symmetrically meshed and connected to the left and right sides of the gear II 39 through the rack. The driving motor drives the gear II 39 to rotate, so that the gear II 39 drives the slide bars II 41 on both sides to slide relatively along their respective slide seats II 40, thereby realizing the relative approach or relative distance of the two longitudinal slide seats II 27 along the guide rail III 26, and realizing the adjustment of the two lower box cover opening mechanisms along the length direction of the packaging box 7, which is convenient for adapting to special-shaped cigarette packaging boxes of different length specifications.

[0047] As attached Figure 3 As shown, the spacing adjustment mechanism II comprises a gear I19 rotatably mounted on the driving motor and two slide bars I21 respectively arranged at the left and right ends of the gear I19 and horizontally inserted in the slide seat I20. The slide seat I20 is mounted on the upper slide seat 11. The two slide bars I21 are respectively connected to a longitudinal slide seat I5. The slide bar I21 is provided with a rack along its length direction. The two slide bars I21 are symmetrically meshed and connected to the left and right sides of the gear I19 through the racks. The driving motor drives the gear I19 to rotate, so that the gear I19 drives the slide bars I21 on both sides to slide relatively along their respective slide seats I20, thereby realizing the relative approach or relative distance of the two longitudinal slide seats I5 along the guide rail I12, realizing the adjustment of the two upper box cover opening mechanisms and the two side box cover opening mechanisms along the length direction of the packaging box 7, and conveniently adapting to special-shaped cigarette packaging boxes of different length specifications.

[0048] As attached Figure 2As shown, it can also include a guide rail II 13 horizontally arranged on the longitudinal slide seat I5 in the left-right direction, a transverse slide seat 14 slidably installed on the guide rail II 13, and a cylinder III 15 whose tail end is fixed on the longitudinal slide seat I5 and is horizontally arranged in the left-right direction. The swing cylinder I 16 is installed on the transverse slide seat 14, and the piston rod head end of the cylinder III 15 is connected to the transverse slide seat 14. When the piston rod of the cylinder III 15 extends outward, it drives the transverse slide seat 14 to move outward, and at this time, the distance between the swing cylinder I 16 and the swing cylinder II 17 becomes larger. When the piston rod of the cylinder III 15 retracts inward, it drives the transverse slide seat 14 to move inward, and at this time, the distance between the swing cylinder I 16 and the swing cylinder II 17 becomes smaller, thereby realizing the adjustment of the side box cover opening mechanism along the width direction of the packaging box 7, which is convenient for adapting to special-shaped cigarette packaging boxes with different width specifications.

[0049] Further, as attached Figure 7 As shown, it also includes a cylinder V37 vertically arranged on the frame 1 and a baffle 38 installed at the head end of the piston rod of the cylinder V37. When the piston rod of the cylinder V37 is fully extended and when the packaging box 7 moves to the middle position of the two lower box cover opening mechanisms, the packaging box 7 contacts the baffle 38. The baffle 38 plays a positioning role, so that it is convenient to stop the packaging box 7 after it moves to the right position, ensuring that each box cover opening mechanism can smoothly absorb the corresponding box cover.

[0050] As attached Figure 5 As shown, it also includes a guide ramp 8 obliquely mounted on the lower seat 33 and located at the tail end of the conveyor belt 6. When the piston rod of the cylinder II 10 is fully retracted, the upper end of the guide ramp 8 is at the same height as the upper end surface of the conveyor belt 6. When the upper cover, lower cover and side cover of the packaging box 7 are all opened, the lower seat 33 moves downward, so that the upper end of the guide ramp 8 is at the same height as the upper end surface of the conveyor belt 6. The conveyor belt 6 slides the packaging box downward through the guide ramp 8 to the next station, which is convenient for outputting the packaging box.
