[0037] Example 1:

[0038] In this example, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , a cartoning mechanism for corrugated cardboard includes a frame 1, a sliding table 2, a first turntable 3, a first suction cup 4, a second turntable 5, a second suction cup 6, a folding plate device 7, a bottom support 8 and a guide rod 9;

[0039] The sliding table 2 is driven by a motor and slidably mounted on the track of the frame 1;

[0040] The first turntable 3 and the second turntable 5 are coaxially arranged and rotatably mounted on the slide 2, and the first turntable 3 and the second turntable 5 are respectively driven by motors;

[0041] The first suction cup 4 and the second suction cup 6 are respectively mounted on the first turntable 3 and the second turntable 5 through a support arm 10, and an angle of 0 - 360° can be formed between the first suction cup 4 and the second suction cup 6;

[0042] The folding plate device 7 is mounted on the support arm 10 and is adapted to the first suction cup 4;

[0043] The bottom support 8 is mounted on the frame 1 and is in the same direction as the advancing direction of the sliding table 2;

[0044] The guide rods 9 are mounted on the frame 1 and are located on both sides of the bottom support 8, and the two guide rods 9 gradually approach and increase in height along the advancing direction of the sliding table 2.

[0045] The cardboard used for this cartoning mechanism is the slotted and scored cardboard.

[0046] Before taking the board, the first turntable 3 and the second turntable 5 are driven by motors, and the working surfaces of the first suction cup 4 and the second suction cup 6 are in the same plane; ’

[0047] Then the sliding table 2 moves towards the cardboard under the drive of the motor until the suction cups hold the cardboard, and then the sliding table 2 retreats in the direction away from the cardboard, leaving a space for the first suction cup 4 and the second suction cup 6 to open the box, and the sliding table 2 stops;

[0048] At this time, the box - opening step is entered. Under the drive of the motor, the first turntable 3 and the second turntable 5 rotate independently, and the first suction cup 4 and the second suction cup 6 form a certain box - opening angle. For example, in Figures 1-2 , a 90° box - opening action forms a "mouth" - shaped carton. At the same time, the folding plate device folds one of the bottom plates at the bottom of the "mouth" - shaped carton, which is one of the cartoning actions. In addition, this action also prepares for the carton to avoid the bottom support 8 when advancing;

[0049] The last slide 2 continues to move, and the bottom holder 8 and the two guide rods 9 fold the remaining three bottom boards of the "mouth" shaped carton bottom, and finally obtain a carton with an upper opening for packaging articles.

[0050] It is worth noting that the angle between the first suction cup 4 and the second suction cup 6 changes greatly, and is suitable for more types of cartons.

[0051] Preferably, the folding plate device 7 comprises a cylinder 11 and a folding plate 12, the folding plate 12 is rotatably installed on the support arm 10, and the two ends of the cylinder 11 are rotatably connected with the support arm 10 and the folding plate 12 respectively.

[0052] The cylinder 11 is extended to rotate with the folding plate 12, and one end of the folding plate 12 is raised to fold the bottom board of the carton.

[0053] Preferably, the slide 2 is provided with a proximity sensor for the first rotary table 3 and the second rotary table 5 respectively.

[0054] The proximity sensors are arranged at different positions to control the rotation angle of the first rotary table 3 and the second rotary table 5, and to realize fine adjustment when the size of the carton changes.

[0059] The motor drives the rotation of the lead screw, and the sliding block moves on the rack 1 under the action of the lead screw. The pushing speed of the paperboard pushing plate 15 is controlled by the rotation speed of the motor.

[0060] Preferably, the discharge end of the paperboard storage track 14 is provided with a paperboard-adapted anti-falling block 17.

[0061] The anti-falling block 17 is used to prevent the paperboard in the paperboard storage mechanism 13 from falling down, and the anti-falling block 17 is not too large to ensure that the suction cup can smoothly take out the paperboard.

[0062] Embodiment three:

[0063] On the basis of the above-mentioned embodiments, this embodiment shows that the discharge side of the rack 1 is provided with a carton guide table 18, and the inner side of the carton guide table 18 is provided with a belt conveyor 19.
