Description

Technical Field

[0001] The utility model relates to packaging equipment, in particular to a box suction and conveying mechanism of a box packing machine. Background Art

[0002] The cartoning machine is a common packaging equipment. Its working principle is to feed the material into an empty packaging box, and then fold the box tongue of the packaging box inward and insert it into the packaging box to close the packaging box. During operation, the packaging box needs to be driven by the box suction conveying mechanism to be sent to the box conveying belt. The traditional box suction conveying mechanism generally includes an inclined stacking rack, and then a swingable suction rod is set at the bottom of the stacking rack to achieve the suction and conveying of the packaging box. The defects of this structure are: because the stacking rack is inclined, its height often needs to be set higher, and the feeding operation is more troublesome. Moreover, the box body does not fall smoothly on the stacking rack simply by relying on the gravity of the packaging box. At the same time, the downward suction and swinging conveying of the suction rod and the cooperation with the box opening component to open the box cannot guarantee the stability of the shape of the box body after opening.

[0006] The suction box rack is provided with two groups on the left and right sides.

[0007] The number of the suction box racks is odd and they are evenly arranged on the rotating shaft.

[0008] The rotating drive assembly includes a first motor, the output end of the first motor is connected to the driving shaft, the driving shaft is connected to the rotating disk, the driving shaft is connected to a first transmission wheel, a transmission belt is wound around the first transmission wheel, the transmission belt is wound around a second transmission wheel, and the second transmission wheel is connected to the rotating shaft.

[0009] The material baffle assembly includes side baffles arranged on both sides of the conveyor belt discharge end, the side baffles are connected with side baffle strips, an upper baffle is arranged on the upper side of the conveyor belt discharge end, and an upper baffle is installed on the upper baffle.

[0010] One end of the box stacking frame is connected to a lifting block, a guide column is passed through the lifting block, and the lifting block is screwed to an adjusting screw.

[0011] The box suction and conveying mechanism of the cartoning machine of the above technical solution adopts a horizontally arranged conveyor belt for stacking and actively conveying the box bodies, which makes the stacking of the box bodies more convenient and the conveying of the box bodies more stable and reliable. At the same time, a rotating box suction rack is adopted and driven by an eccentrically arranged rotating shaft and a rotating disk, so that the movement stroke of the box suction rack is more reasonable, and it can better cooperate with the box opening component to realize the opening of the packaging box.

[0016] 1. As shown in the figure, the box suction conveying mechanism of the cartoning machine disclosed in the utility model has a box body stacking rack 5, on which a conveyor belt 6 for stacking boxes is arranged, the conveyor belt 6 is arranged horizontally, and a material blocking assembly is arranged at the discharge end of the conveyor belt 6. Specifically, the material blocking assembly includes side baffles 7 arranged on both sides of the discharge end of the conveyor belt 6, and side baffles 8 are connected to the side baffles 7. An upper baffle 10 is arranged on the upper side of the discharge end of the conveyor belt 6, and an upper block 9 is installed on the upper baffle 10. A rotating disk 15 is arranged on one side of the conveyor belt 6, and a rotating shaft 14 is eccentrically arranged on the rotating disk 15. The rotating drive assembly can drive the rotating disk 15 and the rotating shaft 14 to rotate. Specifically, the rotating drive assembly includes a first motor 17, and the output end of the first motor 17 is connected to the driving shaft 16, and the driving shaft 16 is connected to the rotating disk 15. A first transmission wheel 18 is connected to the driving shaft 16, and a transmission belt 19 is wound around the first transmission wheel 18. The transmission belt 19 is wound around the second transmission wheel 20, and the second transmission wheel 20 is connected to the rotating shaft 14. A suction box rack 12 is arranged around the rotating shaft 14, and the number of the suction box racks 12 is odd and evenly arranged on the rotating shaft 14. A suction nozzle 11 and an L-shaped box pressing rod 13 are installed on the suction box rack 12. After the suction nozzle 11 releases the box body and separates from the box body, the box pressing rod 13 can press the top surface of the box body. Furthermore, two groups of suction box racks 12 are arranged on the left and right sides, which can realize suction and transportation on both sides of the box body and improve its transportation stability. One end of the box body stacking rack 5 is connected to the lifting block 3, and the lifting block 3 is provided with a guide column 1. The lifting block 3 is screwed with the adjusting screw 2, and the adjusting screw 2 is connected with the adjusting rod 4 through the bevel gear transmission group. By controlling the rotation of the adjusting screw 2, the lifting block 3 and the box body stacking rack 5 can be driven to rise and fall, thereby adjusting the height position of the box body output.

[0017] The working principle of the utility model is as follows: the folded box bodies are stacked and transported on the conveyor belt 6. When the box bodies are transported to the material blocking assembly, they are blocked and positioned. Then, as the rotating disk 15 and the rotating shaft 14 rotate, the suction nozzle 11 is driven to move to the discharge end of the conveyor belt 6 to suck the packaging bag. Then, as the rotating disk 15 and the rotating shaft 14 continue to rotate, the sucked folded box bodies are driven to cooperate with the box opening assembly to realize the opening of the box bodies. Then, the box bodies are sent to the box feeding conveyor belt, the suction nozzle 11 releases the box bodies, and after the suction nozzle 11 is separated from the box bodies, the box pressing rod 13 squeezes the top of the box body after it is opened to provide a force to avoid rebound and shrinkage of the box body after it is opened, and also ensure that the position of the box body will not shift. Then, the box pressing rod 13 is separated from the box body, and the box body is driven by the box feeding conveyor belt to the next processing station.

[0018] The structure of the utility model adopts a horizontally arranged conveyor belt for stacking and actively conveying the box bodies, which makes the stacking of the box bodies more convenient and the conveying of the box bodies more stable and reliable. At the same time, a rotating box suction rack is adopted and driven by an eccentrically arranged rotating shaft and a rotating disk, so that the action stroke of the box suction rack is more reasonable, and it can better cooperate with the box opening component to realize the opening of the packaging box. In addition, by arranging a box pressing rod, the top positioning and pressing of the box body after opening can be realized, which can ensure that the shape of the box body will not rebound and deform after opening, and its position will not shift.
