[0019] Reference Figures 1 to 4 The embodiments of the present invention are further described.

[0020] The present invention discloses an unpacking mechanism for a cartoning machine, comprising a packing box silo 1 and a fixed bracket 2 arranged on one side of the packing box silo 1, wherein the fixed bracket 2 is provided with a driving plate 3 which can slide back and forth toward the packing box silo 1, and the driving plate 3 is installed with an unpacking mechanism 4, wherein the unpacking mechanism 4 comprises a driving motor 40, a rotating arm 41 and a swing arm 42, wherein the driving motor 40 is provided with a fixed shell 43 outside, and the driving motor 40 is fixed to the driving plate 3 through the fixed shell 43, and the rotating arm 41 is fixed to the output shaft of the driving motor 40, and the rotating arm 41 can be driven by the driving motor 40 to swing back and forth toward the packing box silo 1, and the swing arm 42 is hinged to one end of the rotating arm 41 close to the packing box silo 1, and a connecting rod 44 is hinged at the bottom of the swing arm 42, and the end of the connecting rod 44 is hinged and fixed to the fixed shell 43, and at least two first suction cups 45 are arranged on the rotating arm 41.

[0021] Furthermore, at least two slidably matched U-shaped sliding blocks 46 are provided at one end of the rotating arm 41 away from the swing arm 42, and a strip groove 410 is provided on the rotating arm 41 along the length direction of the rotating arm 41. The first suction cup 45 is fixed on the U-shaped sliding block 46, and the first suction cup 45 is located in the strip groove 410 for sucking the cartons in the packaging box silo 1.

[0022] Furthermore, a box support plate 420 is fixed to the swing arm 42, and the box support plate 420 is arranged in a cross shape. The box support plate 420 makes the swing arm 42 more stable when the box is opened.

[0023] Furthermore, one end of the rotating arm 41 is bent downward to form a fixed arm 412 , and an end of the fixed arm 412 is fixedly connected to the output shaft of the driving motor 40 .

[0024] Furthermore, a through slot 411 is provided at one end of the rotating arm 41 close to the packaging box silo 1 , and the connecting rod 44 passes through the through slot 411 and is hingedly fixed to the fixed shell 43 .

[0025] Furthermore, a limiter 30 is fixed on the driving plate 3, and the limiter 30 is horizontally arranged on the side of the fixed housing 43 away from the packaging box silo 1. By setting the limiter 30, the rotating arm 41 can be limited by the limiter 30 when it is rotated to the right position, so as to prevent the rotating arm 41 from rotating too far.

[0026] Furthermore, L-shaped side plates 460 are respectively provided on both sides of the U-shaped sliding block 46. The L-shaped side plates 460 enable the box to better fit with the rotating arm 41, and the structure is more stable.

[0027] Furthermore, two guide rails 20 are respectively arranged along the length direction of the fixed bracket 2 on the upper and lower sides, and a sliding block 31 is arranged at the bottom of the driving plate 3 to slide with the two guide rails 20. A driving belt 21 is also arranged on the fixed bracket 2 along the length direction of the fixed bracket 2. The driving belt 21 is driven to rotate by a servo motor 33, and a connecting block 32 fixed on the driving belt 21 is arranged at the bottom of the driving plate 3. Figure 2 As shown, the servo motor 33 drives the driving belt 21 to rotate back and forth. When the driving belt 21 rotates back and forth, it drives the driving plate 3 to slide left and right along the two guide rails 20, thereby driving the opening mechanism 4.

[0028] Furthermore, the box support plate 420 is provided with second suction cups 421 on both sides relative to the swing arm 42. The second suction cups 421 enable the swing arm 42 to better absorb and fix the box, greatly improving the stability of the carton when it is opened.

[0029] Working principle: When opening a box, the unpacking mechanism 4 of the present invention first Figure 1 As shown, the driving motor 40 drives the rotating arm 41 to rotate to the same angle as the packaging box silo 1. At this time, the swing arm 42 is driven by the connecting rod 44 to the same plane as the rotating arm 41 to form a material picking surface, and then the driving plate 3 drives the unpacking mechanism 4 to move toward the packaging box silo 1 to pick up materials. When the unpacking mechanism 4 is driven to the packaging box silo 1 by the driving plate 3 and is close to it, the first suction cup 45 provided on the rotating arm 41 will suck the folded box body, and the rotating arm 41 and the swing arm 42 are respectively located at two surfaces of the box body. When the first suction cup 45 sucks the box body, the driving plate 3 drives the unpacking mechanism 4 away from the packaging box silo 1.

[0030] When the unpacking mechanism 4 is far enough away from the packaging box silo 1, Figure 2 As shown, the driving motor 40 drives the rotating arm 41 to rotate to the horizontal direction, and at this time, the swing arm 42 is driven to rotate to a state perpendicular to the rotating arm 41 through the connecting rod 44. During the rotation of the swing arm 42, one side of the folded carton is fixed to the rotating arm 41 through the first suction cup 45, and the other side is squeezed by the rotation of the swing arm 42 so that the carton is slowly opened as a whole. When the swing arm 42 rotates to a state perpendicular to the rotating arm 41, the carton is in a square opened state as a whole. When the carton is opened as a whole, the first suction cup 45 loses its adsorption force on the carton, so that the opened carton can be removed for the next step of packing.

[0031] In summary, the box opening mechanism 4 of the present invention can open the box body through the swing arm control, which is convenient for loading the box body and thus improves the production efficiency.

[0032] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
