[0029] The rotating sleeve 3 and the drive wheel 4 are respectively fixed on the drive shaft 2, with the drive wheel 4 located behind the rotating sleeve 3 and the vent 11 located in front of the rotating sleeve 3.

[0030] The rotating sleeve 3 is provided with four suction rod shafts 5 arranged in a circular pattern. Each suction rod shaft 5 is connected to the rotating sleeve 3 through a driven bearing seat 12. Every two suction rod shafts 5 are connected to the drive wheel 4 through a set of belt drive structure 13. Each driven bearing seat 12 is provided with an air inlet 14. Each suction rod shaft 5 is provided with an air passage 15. The air inlet 14 is connected to the air supply nozzle 8 and the air passage 15 respectively. Each suction rod shaft 5 is fitted with a rotating arm 6 through a star-shaped sealing ring 16. The rotating arm 6 is provided with a suction box plate 17, which is connected to the air passage 15.

[0031] The rear end of the drive shaft 2 is connected to the rotary drive mechanism 18, and the side of the rotating sleeve 3 is provided with an opening rod 19, on which an opening suction cup 20 is provided.

[0032] A flange 43 is provided on the drive shaft 2, and the rotating sleeve 3 is fixed to the flange 43.

[0033] The rotating sleeve 3 is covered with a protective cover 44, and the suction rod shaft 5 passes through and extends out of the protective cover 44 before being connected to the rotating arm 6.

[0034] The inner wall of the driven bearing housing 12 is provided with a first annular groove 21 and a second annular groove 22. The air inlet 14 is located between the first annular groove 21 and the second annular groove 22. Rotating glyphs 23 are respectively provided in the first annular groove 21 and the second annular groove 22.

[0035] The rotary drive mechanism 18 includes a drive motor 24 and a coupling 25. The drive motor 24 and the coupling 25 are connected, and the coupling 25 is connected to the drive shaft 2. The coupling 25 is disposed inside the top sleeve 26.

[0036] The belt drive structure 13 includes a drive belt 27, a drive pulley 28, and a tension pulley 29. The drive pulley 28 is fixed on the suction rod shaft 5, and the tension pulley 29 is mounted on the rotating sleeve 3. The drive belt 27 is wound around the drive wheel 4, the drive pulley 28, and the tension pulley 29.

[0037] The drive wheel 28 is connected to the suction rod shaft 5 via the expansion sleeve 30.

[0038] Working principle: When a negative pressure is formed on the suction cup 17, the air supply nozzle 8 is connected to the air source. The negative pressure generated by the air source enters the air supply channel 10 through the air inlet channel, and then enters the air inlet nozzle 14 through the air vent 11. The air inlet nozzle 14 and the air inlet passage 15 create a negative pressure on the suction cup 17 to suck up the paper box 45. At the same time, the drive motor 24 drives the drive shaft 2 to rotate through the coupling 25. The drive shaft 2 drives the rotating sleeve 3 to rotate. While the suction rod shaft 5 and the rotating arm 6 revolve with the rotating sleeve 3, the drive shaft 2 drives the drive wheel 4 to rotate. The drive wheel 4 drives the suction rod shaft 5 to rotate on its own axis through the transmission belt 27 and the transmission wheel 28. Under the action of rotation, the movement trajectory of the suction cup 17 is an equilateral triangle with three sides that are concave arcs. At the box picking station, the suction cup 17 picks up the paper box 45, and then the paper box 45 encounters the opening suction cup 20 on the travel path. The opening suction cup 20 is attached to the paper box 45. At this time, the suction cup 17 and the opening suction cup 20 are opposite each other, that is, they are attached to the opposite surface of the paper box 45. Through the interaction between the suction cup 17 and the opening suction cup 20, the folded paper box 45 is opened and formed, thus realizing the opening of the paper box 45. Finally, at the lowering station, the suction cup 17 places the fully opened paper box 45 from top to bottom onto the paper box 45 conveyor belt.

[0039] When it is necessary to adjust the extension length of the rotating arm 6, simply pull the rotating arm 6 outward. During the process of pulling the rotating arm 6 outward, the star-shaped sealing ring moves along the axial direction without affecting the airtightness.

[0040] The spindle seat 1 is mounted on the mounting base plate 31, the mounting base plate 31 is mounted on the guide mechanism 32, and the spindle seat 1 is connected to the lifting mechanism 33.

[0041] The lifting mechanism 33 includes a worm gear 34, a screw 35, a servo motor 36, and a worm 37. The worm gear 34 is disposed in a worm gear seat 38, which is disposed on a worm gear box seat 39. The worm gear 34 is fitted onto the screw 35. The worm gear 34 and the worm 37 mesh with each other. The worm 37 is connected to the servo motor 36. The screw 35 is connected to the main shaft seat 1 through a fixing block 40.

[0042] The guide mechanism 32 includes a guide rail 41 and a slider 42. The slider 42 is connected to the mounting base plate 31 and is mounted on the guide rail 41.

[0043] When the height of the suction cup 17 needs to be adjusted, during the opening of the box, the height of the suction cup 17 is made to match the height of the opening suction cup 20. The servo motor 36 drives the worm gear 37 to rotate the worm wheel 34. The inner wall of the worm wheel 34 is provided with threads that mesh with the screw 35. When the worm wheel 34 rotates, the screw 35 rises and falls. The screw 35 drives the main shaft seat 1 to rise and fall along the guide rail 41, thereby realizing the adjustment of the height of the suction cup 17.

[0044] The above detailed description is a specific description of a feasible embodiment of the present utility model. This embodiment is not intended to limit the patent scope of the present utility model. All equivalent implementations or modifications that do not depart from the present utility model should be included in the patent scope of this case.
