[0048] Embodiment:

[0049] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 , the embodiment discloses an opening device of a packaging box, which comprises a rack (not shown in the figure), a feeding groove 10, a rotating disc 20, a motor 30, a rotor 40, a supporting rod 50, a suction cup 60 and a pressing rod 70.

[0050] Specifically, the feeding groove 10 is arranged in an inclined manner on the rack, one end of the feeding groove 10 is high, and the other end is low, the horizontal position of the low end of the feeding groove 10 is the discharge port thereof, the discharge port is an open structure, and a limiting structure is arranged on the top and bottom of the discharge port, respectively, the limiting structure is a small triangular structure protruding inward of the discharge port. All the paper boxes that need to be unfolded are stacked in the feeding groove 10, and all the paper boxes are prevented from sliding downward by the limiting structure.

[0051] A motor 30 is fixedly arranged on the rack, the output shaft of the motor 30 is arranged in a horizontal direction and perpendicular to the length direction of the feeding groove 10. A rotating disc 20 is fixedly arranged on the output shaft of the motor 30, and the rotating disc 20 and the output shaft of the motor 30 are coaxially connected. The rotating disc 20 can be continuously driven to rotate by the motor 30.

[0052] Among them, two movable holes are arranged on the rotating disc 20, the two movable holes are circular and symmetrically arranged about the axis of the rotating disc 20, so that the two movable holes are respectively close to the two sides of the rotating disc 20.

[0053] A rotor 40 is arranged in each of the two movable holes on the rotating disc 20, the rotor 40 is power-connected with the output shaft of the motor 30, so that the two rotors 40 synchronously rotate when the rotating disc 20 is driven to rotate by the motor 30, and the rotating direction of the rotor 40 is opposite to the rotating direction of the rotating disc 20.

[0054] One end of a supporting rod 50 is fixedly arranged on the rotor 40, and the supporting rod 50 is L-shaped, one end of the supporting rod 50 extends along the axis direction of the rotor 40, the other end of the supporting rod 50 extends perpendicular to the axis direction of the rotor 40, and a suction disc 60 is arranged on the end of the supporting rod 50 perpendicular to the axis of the rotor 40. One supporting rod 50 is arranged on each of the two rotors 40.

[0055] A through hole is further arranged on the rotor 40, the through hole is also a circular hole, and a pressing rod 70 is rotatably arranged in the through hole, the pressing rod 70 is U-shaped, one end of the pressing rod 70 is indirectly connected with the output shaft of the motor 30, so that the pressing rod 70 can rotate relative to the supporting rod 50.

[0056] In this embodiment, the feeding groove 10 is arranged on the rack, and all the paper boxes that need to be opened are stacked in the feeding groove 10. Since the feeding groove 10 is arranged in an inclined manner, when the paper boxes at the bottom are taken away, the paper boxes above will automatically move downward.

Through the rotation of the rotors 40, the suction cups 60 connected to the rotors 40 through the supporting rods 50 rotate. When the rotors 40 approach the discharge port, the suction cups 60 are just in the discharge port, and under the continuous rotation of the rotors 40, the supporting rods 50 give the suction cups 60 a pressure, so that when the rotors 40 move away from the discharge port, the suction cups 60 suck a carton in the discharge port, and then in the continuous rotation process of the rotors 40, the pressing rods 70 rotate relative to the rotors 40, so that the pressing rods 70 press on the side of the carton, and in the continuous movement, the carton is unfolded.

[0058] The technical scheme has a simple mechanical structure, so that the use and maintenance in the later stage are simpler, thereby the cost of production can be effectively reduced.

[0059] In one specific embodiment:

[0060] The opening device further comprises a discharge chute 81, a conveying belt 82, a rod 83 and a pressing plate 84. The discharge chute 81 is arranged on the frame in the horizontal direction, and the discharge chute 81 is located below the rotating disc 20.

[0061] A plurality of rods 83 are arranged on the conveying belt 82, and the rods 83 are arranged in the vertical direction. The front side of the rod 83 is a slope structure, so that the width of the end of the rod 83 connected to the conveying belt 82 is greater than the width of the top end.

[0062] The distance between the adjacent two rods 83 is equal, and the distance is equal to the width of the opened carton. The pressing plate 84 is located at the top of the discharge chute 81.

[0063] In the working process, when the rotating disc 20 rotates, the carton is conveyed to the oblique upper side of the discharge chute 81 through the supporting rods 50 and the suction cups 60. Due to the action of the pressing rods 70, the carton has been opened to a certain shape (at this time, the cross section of the carton is a parallelogram structure). Then the rotating disc 20 continuously rotates, so that one side of the carton is in contact with the slope on the rod 83. When the rotor 40 reaches the lowest position under the driving of the rotating disc 20, the carton is completely unfolded under the action of the rod 83 and is completely placed between the adjacent two rods 83. Then under the action of the pressing plate 84, the front end of the carton is pressed, so that when the rotating disc 20 rotates, the carton is rotated and separated from the suction cup 60. Finally, the conveying belt 82 drives the carton to move.

[0064] In another specific embodiment:

[0065] The opening device further comprises an inner tooth ring 100, wherein the inner tooth ring 100 is fixedly arranged on the frame, and the axis of the inner tooth ring 100 is collinear with the output shaft axis of the motor 30 and the axis of the rotating disc 20.

[0071] The large arc-shaped tooth 92 is an inner tooth structure, and the small arc-shaped tooth 93 is an outer tooth structure. The two ends of the large arc-shaped tooth 92 are close to the two ends of the small arc-shaped tooth 93, and the two ends of the large arc-shaped tooth 92 and the two ends of the small arc-shaped tooth 93 are on the same straight line, and the distance between them is a diameter of the rotor 40.

[0072] In addition, a pinion 94 is further arranged at the end of each of the two pressing rods 70, and the pinion 94 can be engaged with the large arc-shaped tooth 92 or the small arc-shaped tooth 93. The difference between the pitch circle radius of the large arc-shaped tooth 92 and the pitch circle radius of the small arc-shaped tooth 93 is equal to the pitch circle diameter of the pinion 94.

[0073] Since the pressing rod 70 is U-shaped, it is located on one side of the supporting rod 50, and the pressing rod 70 is mainly used for once extrusion action to the side of the carton, therefore, in the embodiment, the connecting rod 91 is arranged, the motor 30 is used for synchronous driving the rotating disc 20 and the two rotors 40 to move together, in the rotating process of the rotor 40, the pinion 94 rolls on the large arc-shaped tooth 92 and the small arc-shaped tooth 93, two different rotating directions are made, and the once pressing action is realized.

[0074] Preferably, one end of the pressing rod 70 is arranged on a rotating shaft, the rotating shaft is arranged in the through hole, and the small size is arranged on the rotating shaft.

[0075] Since the gear ratio of the inner tooth ring 100 and the gear in the technical scheme is 4:1, the two supporting rods 50 and the two pressing rods 70 are consistent in the direction, so as to meet the design requirement.

[0076] The above embodiment only expresses the specific implementation of the utility model, the description is more specific and detailed, but it cannot be understood as the limitation of the patent range of the utility model. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of deformations and improvements can be made, which belong to the protection range of the utility model.
