[0031] The present invention relates to a material suction mechanism for a carton opener. Through the arrangement of a first X-shaped mounting frame 201, a second X-shaped mounting frame 202, a rotating shaft 203, a winding shaft 204, a first transmission belt 205, a second transmission belt 206, a third transmission belt 207, a first motor 208, a linkage member, and a suction cup 209 in a material suction assembly 20, the mechanism can effectively adapt to the suction of cartons of various specifications, achieve stable suction, ensure the stability of subsequent carton opening processes, and is suitable for industrial applications.

[0032] In a specific embodiment, the rotating shaft 203 is provided with a first transmission wheel at one end located on the first X mounting frame, and a second transmission wheel is provided at one end located on the second X mounting frame; a third transmission wheel is provided on the outside of the winding shaft 204; a first transmission belt 205 is connected to two of the oppositely arranged first transmission wheels; a second transmission belt 206 is connected to the other two opposite first transmission wheels; and a third transmission belt 207 is respectively wound around the first transmission shaft and the winding shaft 204 through the second transmission wheel and the third transmission wheel.

[0033] In a specific embodiment, the linkage includes a connecting plate 210 and a mounting plate 211; two connecting plates 210 are respectively located at the two ends of the first transmission belt 205, and are respectively connected to the opposite sides of the first transmission belt 205; the other two connecting plates 210 are respectively located at the two ends of the second transmission belt 206, and are respectively connected to the opposite sides of the second transmission belt 206; the connecting plate 210 extends out of the first X-shaped mounting frame 201 toward one end of the storage rack 10; the mounting plate 211 is installed on one end of the connecting plate 210 extending out of the first X-shaped mounting frame 201; the suction cup 209 is installed on the mounting plate 211.

[0034] In this embodiment, during operation, when the first transmission belt 205 and the second transmission belt 206 rotate synchronously, they can effectively drive the various connections to retract or expand with the rotation, thereby driving the mounting plate 211 and the suction cup 209 connected to the mounting plate 211 to retract and expand, so as to effectively adjust the suction range according to the size of the carton; further, the first X-shaped mounting frame 201 is provided with an avoidance groove 212 for the movement of the connecting plate 210 on the side facing the storage rack 10, and the side of the first X-shaped mounting frame 201 is provided with a slide rail 213 connected to the mounting plate 211 for driving the directional movement of the mounting plate 211.

[0035] In a specific embodiment, the suction device also includes a telescopic column 214, a first cylinder 215 and a horizontal connecting rod 216; the horizontal connecting rod 216 is installed on the side of the second X-shaped mounting frame 202 away from the first X-shaped mounting frame 201, and is connected to the first drive assembly 30; there are four telescopic columns 214, and the four telescopic columns 214 are respectively installed on the four ends of the second X-shaped mounting frame 202 away from the side of the first X-shaped mounting frame 201, and are connected to the horizontal connecting rod 216; the first cylinder 215 is installed between the four telescopic columns 214, and its bottom is installed on the horizontal connecting rod 216, and its power output end is connected to the center of the second X-shaped mounting frame 202. Specifically, in this embodiment, the first driving assembly 30 of the studio drives the horizontal connecting rod 216 to move toward the storage rack 10, thereby driving the first X-shaped mounting frame 201 and the second X-shaped mounting frame 202 to move. When the horizontal positions of the first X-shaped mounting frame 201 and the second X-shaped mounting frame 202 need to be adjusted, the first cylinder 215 works, thereby driving the first X-shaped mounting frame 201 and the second X-shaped mounting frame 202 to move. In this process, the telescopic column 214 plays an effective guiding role. Through the arrangement of the first cylinder 215 and the telescopic column 214, this embodiment can realize a secondary displacement of the first X-shaped mounting frame 201 and the second X-shaped mounting frame 202 after the first driving assembly 30 has initially displaced the first X-shaped mounting frame 201 and the second X-shaped mounting frame 202, thereby greatly satisfying the displacement requirements of the first X-shaped mounting frame 201 and the second X-shaped mounting frame 202 when unpacking and sucking materials.

Specifically, in this embodiment, during operation, the second motor 303 drives the screw rod 302 to rotate, which in turn drives the first movable block 301 to drive the horizontal connecting rod 216 to move, thereby driving the suction cup 209 to move.

[0037] In a specific embodiment, the first movable base further includes a first guide rod 304 disposed parallel to the screw rod 302 and slidably connected to the first movable block 301. Specifically, in this embodiment, when the screw rod 302 rotates, the first guide rod 304 effectively ensures the directional mobility of the first movable block 301.

[0038] In a specific embodiment, the first drive assembly 30 further includes a second movable base; the second movable base includes a linkage rod 305 connected to the second end of the horizontal connecting rod 216, a second movable block 306 mounted at the bottom of the linkage rod 305, and a second guide rod 307 slidably connected to the second movable block 306 to ensure that the second movable block 306 moves in a directional manner toward the storage rack 10. Specifically, in this embodiment, the second motor 303 drives the screw rod 302 to rotate, thereby driving the horizontal connecting rod 216 to move. When the horizontal connecting rod 216 moves, it drives the linkage rod 305 to move. The provision of the second movable block 306 and the second guide rod 307 ensures the directional movement of the second end of the horizontal connecting rod 216, thereby ensuring the stability of the horizontal connecting rod 216 during movement.

[0039] In a specific embodiment, the system further includes a curved guide rod 40 disposed within one of the openings of the first X-shaped mounting frame 201 for unpacking the carton when the suction assembly 20 sucks out the carton, and a second drive assembly 50 connected to the curved guide rod 40 for driving the curved guide rod 40 to move toward or away from the opening of the first X-shaped mounting frame 201. Specifically, when the carton size is small, the suction nozzles are retracted, and at this time, the second drive assembly 50 drives the curved guide rod 40 to move relative to the opening, thereby enabling the carton to be unpacked smoothly when the suction nozzles suck out the carton; the same applies in reverse.

[0040] In a specific embodiment, the second driving assembly 50 includes a second cylinder 501 connected to an end of the arc-shaped guide rod 40 for driving the arc-shaped guide rod 40 to move toward or away from the opening of the first X-shaped mounting bracket 201 .

In this embodiment, the vertical position of the storage rack 10 can be effectively adjusted by setting the lifting assembly, so as to effectively cooperate with the suction assembly 20 to meet the unpacking process of each carton.

[0042] The present invention relates to a material suction mechanism for a carton opener. Through the arrangement of a first X-shaped mounting frame 201, a second X-shaped mounting frame 202, a rotating shaft 203, a winding shaft 204, a first transmission belt 205, a second transmission belt 206, a third transmission belt 207, a first motor 208, a linkage member, and a suction cup 209 in a material suction assembly 20, the mechanism can effectively adapt to the suction of cartons of various specifications, achieve stable suction, ensure the stability of subsequent carton opening processes, and is suitable for industrial applications.
