DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-3 As shown, a paper feed cover mechanism of a cartoning machine comprises a support frame 1, a rotating disk 15 is rotatably connected to the top of the support frame 1, the support frame 1 is provided with a first driving mechanism for driving the rotating disk 15 to rotate, a sealing barrel 20 coaxial with the rotating disk 15 is fixed at the bottom of the rotating disk 15, and a plug-in cylinder 21 fixed on the support frame 1 is plugged in the inside of the sealing barrel 20 through a sealing ring;

[0023] The top of the rotating disk 15 is rotatably connected with a transmission cylinder 12 through a bearing. The transmission cylinder 12 is not concentric with the rotating disk 15. The transmission cylinder 12 can be installed at different positions according to the different displacement ranges of the paper cover. A fixed cylinder 10 is fixed on the top of the transmission cylinder 12. Suction cups 11 are fixed at both ends of the fixed cylinder 10. The suction cups 11 are connected to the fixed cylinder 10. The rotating disk 15 is provided with a second driving mechanism for driving the transmission cylinder 12 to rotate. A connecting component connected to the sealing barrel 20 is provided inside the fixed cylinder 10. The connecting component is rotatably sealed and connected to the electric reversing valve 9 located on the fixed cylinder 10. The electric reversing valve 9 is connected to the suction cup 11 through the fixed cylinder 10.

[0024] When in use, the plug-in cylinder 21 is connected to the external negative pressure device, and the first driving mechanism drives the rotating disk 15 to rotate. At this time, the suction cup 11 is continuously displaced with the rotation of the rotating disk 15, and then the second driving mechanism drives the fixed cylinder 10 and the suction cup 11 to rotate for the second time. When the suction cup 11 moves to the paper cover removal position, the electric reversing valve 9 switches the suction cup 11 to be connected with the connecting component, and the air in the suction cup 11 is discharged from the connecting component, and the suction cup 11 absorbs the paper cover. Then the rotating disk 15 and the suction cup 11 continue to rotate until the suction cup 11 moves to the paper feed cover position. At this time, the electric reversing valve 9 controls the two suction cups 11 to be connected, and the suction cup 11 no longer absorbs the paper cover, and the paper cover falls onto the cartoning machine, and then continues to absorb the paper cover according to the above process and feeds the paper cover into the paper cartoning machine.

[0025] In this embodiment, the first driving mechanism includes a rotating cylinder 4 fixed to the lower side of the rotating disk 15, a driving gear ring 17 fixed to the inner side of the rotating cylinder 4, a driving gear 3 meshed with the driving gear ring 17, and a driving motor 2 fixed to the support frame 1, the driving shaft of the driving motor 2 is connected to the driving gear 3, a fixing ring 16 is fixed to the upper side of the support frame 1, and the rotating cylinder 4 is connected to the fixing ring 16 through a bearing;

[0026] When in use, the driving motor 2 works and drives the rotating drum 4 to rotate through the driving gear 3 and the driving gear ring 17, and the rotating drum 4 drives the rotating disk 15 to rotate. When it is necessary to stop, the driving motor 2 can be turned off.

[0027] In this embodiment, the second driving mechanism includes a rotating motor 5 fixed on a rotating disk 15, a rotating gear 6 connected to the rotating motor 5, and a rotating gear ring 13 fixed on a transmission cylinder 12, and the rotating gear ring 13 is meshed with the rotating gear 6 for transmission;

[0028] When in use, the rotating motor 5 works and drives the transmission cylinder 12 to rotate through the rotating gear 6 and the rotating gear ring 13, and the transmission cylinder 12 drives the fixed cylinder 10 to rotate. When it is necessary to stop, the driving motor 2 can be turned off.

[0029] In this embodiment, the connecting component includes a fixed shaft 7 fixed on the rotating disk 15 and a plug-in tube 8 connected to the electric reversing valve 9 through a pipeline. The fixed shaft 7 is vertically provided with a through hole along the axis, the through hole is connected to the sealing barrel 20 through a pipeline, and the plug-in tube 8 is plugged into the through hole through a sealing ring.

[0030] During use, the plug-in tube 8 cooperates with the through hole so that when the fixing cylinder 10 rotates, the electric reversing valve 9 can still communicate with the through hole, thereby ensuring that the suction cup 11 adsorbs the paper cover.

[0031] In this embodiment, a negative pressure box 14 is fixed on the top of the rotating disk 15, and the negative pressure box 14 is connected to a one-way valve 19 through a pipeline, and the one-way valve 19 is connected to the sealing barrel 20 through a pipeline, and the negative pressure box 14 is connected to the through hole through a pipeline;

[0032] When in use, the negative pressure device draws air from the negative pressure box 14, and the negative pressure box 14 draws air from the suction cup 11. When the negative pressure device is damaged, the one-way valve 19 prevents the air in the negative pressure box 14 from being discharged from the sealing barrel 20, so that the suction cup 11 can continue to work and ensure its use.

[0033] In this embodiment, the bottom of the plug-in tube 21 is connected to an air inlet pipe 18 having one end extending to the bottom of the support frame 1; when in use, the connection with the negative pressure device is achieved through the air inlet pipe 18 to ensure connectivity.

[0034] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein; any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
