Description

Technical Field

[0001] The utility model relates to the technical field of palletizing equipment, in particular to a palletizing and stacking mechanism for producing packaging boxes. Background Art

[0002] Cardboard is the raw material for producing packaging boxes. During the production process of packaging boxes, cardboard needs to be slotted, creased and glued to form the blank of the packaging box. After that, the operator packs the blank of the packaging box and then palletizes it before it can be shipped out of the factory. At present, the palletizing of the blank of the packaging box is mainly carried out by a robotic arm gripper.

[0003] The Chinese utility model patent announcement number is: CN219688715U, which discloses: a fully automatic packaging box stacking equipment, which is equipped with a suction cup to absorb the packaging box, and two screw sleeves are arranged to move towards each other, so that the two limiting clamps can move towards the sides close to each other to clamp the packaging box, and the packaging box is double-clamped to prevent the packaging box from falling when the packaging box is transported, thereby increasing the safety performance. In addition, this device can clamp packaging boxes of different specifications. However, the clamping structure used by it still does not support the packaging box from the bottom of the packaging box, and the packaging box may still fall during transportation. At the same time, the conveyor belt for transporting the packaging box does not have a limiting structure, and the packaging box transported to the push plate may be placed in an incorrect position, which is not convenient for clamping and has poor practicality.

[0031] Embodiment 2: Figure 2-5 As shown, as an improvement to the previous embodiment.

[0032] Specifically, the mounting plate 15 is located on the right side of the top of the vertical plate 14, and the mounting plates 15, springs 17 and limit plates 18 are identical. The two mounting plates 15, springs 17 and limit plates 18 are symmetrically distributed about the vertical plate 14. One end of the spring 17 is fixedly connected to the mounting plate 15, and the other end is fixedly connected to the limit plate 18. The advantage is that a limit assembly is formed by the mounting plate 15, spring 17 and limit plate 18. After the package box is transported to the conveyor belt 16, the package box is limited, so that the package box moves in an orderly manner on the conveyor belt 16, which is convenient for the cylinder 20 to push the package box onto the placement table 1 22.

[0033] Specifically, the movable end of cylinder three 23 passes through the bottom plate 1 and extends to the interior of the placement table 1 22. The center lines of the placement table 1 22, cylinder three 23 and pallet 24 are located on the same vertical line. The pallet 24 is adapted to the placement table 1 22. The advantage is that after the packaging box is pushed onto the placement table 1 22, cylinder three 23 is started to push the pallet 24 upward, so that the four corners of the packaging box are suspended in the air, which is convenient for clamping by the clamping plate 1 12 and the clamping plate 2 13.

[0034] Specifically, cylinder 20 is located on the left side of the vertical plate 14, and placement table 1 22 is located on the right side of the vertical plate 14. Placement table 1 22 and vertical plate 14 are closely connected. The advantage is that when the packaging box is transported to the end of the conveyor belt 16, cylinder 20 is started to push the push plate 21 to push the packaging box onto the placement table 1 22.

[0035] Working principle: When in use, first use the conveyor belt 16 to transport the packaging box. The mounting plate 15, spring 17 and limit plate 18 on the vertical plate 14 form a limit assembly. After the packaging box is transported to the conveyor belt 16, the packaging box is limited so that the packaging box moves on the conveyor belt 16 in an orderly manner, so that the cylinder 20 can push the packaging box to the placement table 1 22. When the packaging box is transported to the end of the conveyor belt 16, the cylinder 20 starts to push the push plate 21 to push the packaging box to the placement table 1 22. At this time, the cylinder 3 23 starts to push the tray 24 upward, so that the four corners of the packaging box are suspended in the air, which is convenient for the clamping of the clamping plate 12 and the clamping plate 2 13. When the packaging box is lifted up, the slider 1 4 slides on the slide rail 1 3, and the slider 2 6 is The cylinder 10 pushes the four connecting blocks 11 away from each other to increase the spacing between the four groups of clamping plates 12. Then the telescopic cylinder 8 works to push the connecting plate 29 downward. When the clamping plate 13 is located below the packaging box, the cylinder 10 controls the clamping plate 12 to retract inward to clamp the packaging box. At the same time, the clamping plate 13 will support the packaging box from the bottom to prevent it from falling during transportation. Then the slider 4 slides on the slide rail 3, and the slider 26 slides on the slide rail 25 to transport the clamped packaging box to the placement table 25. The cylinder 10 pushes the clamping plate 12 to move outward to make the packaging box fall on the placement table 25 to complete the palletizing.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
