Description

Technical Field

[0001] The utility model relates to the technical field of paper box stacking, in particular to a guiding stacking device for packaging paper boxes. Background Technique

[0002] Paper boxes are the most widely used packaging products. According to different materials, there are corrugated paper boxes, single-layer cardboard boxes, etc., with various specifications and models. They are usually used as packages for goods or outer protective materials for items. The volume of the paper box changes according to the size of the goods. Paper boxes usually have product selection patterns and various logos, and are an indispensable part of modern logistics, bearing important responsibilities for packaging, protecting products, and aesthetics.

[0003] In the production line of packaging paper, on the machine tool, the two sides of the cardboard are guided and folded during the transmission of the cardboard by the guiding belt. After folding, the cardboard box is flattened and pasted. The flat paper boxes after folding need to be quantitatively stacked. After stacking, they are centrally transported to the packaging and bundling workshop for stacking and bundling. In this production line, the equipment for stacking paper boxes is installed at the connection of two conveyor beds. There is a height difference between the two conveyor beds. The paper boxes are transported from the low-level conveyor bed to the stacking area for stacking. After stacking, the stacked paper boxes are divided into two by a moving plate, and the stacked paper boxes in the top area are pushed to the high-level conveyor bed to realize the transfer of the stacked paper boxes;

[0004] During the above stacking process, the cardboard boxes are stacked in a way of inserting from the bottom: the first paper box is transported to the stacking area for temporary storage, and the second paper box is stacked secondarily by inserting it into the bottom of the first paper box, and so on. During the stacking process, the top of the stacked paper boxes will always be squeezed by a gravity part for positioning. After stacking to a certain height, the cardboard boxes higher than the high-level conveyor bed area are pushed to the high-level conveyor bed as a whole by the moving plate. During this period, there are the following problems in the stacking of paper boxes: 1. When using the bottom-insertion stacking method, it is difficult to ensure the accuracy of insertion, and it is easy to cause the problem that the cardboard of the paper box gets stuck in the bottom area of the stacked paper box during insertion; 2. By using the gravity part to position the paper boxes during stacking, the stability is poor, and it is easy to cause the problem of the stacked paper box board tipping over. In view of this, we propose a guiding stacking device for packaging paper boxes. Content of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 , a technical solution provided by the present utility model:

[0024] A packaging carton guiding and stacking device includes a transportation base 1. A high-level transmission area 2 and a low-level transmission area 3 are provided on the transportation base 1. A first limiting base 7 is fixedly connected to the transportation base 1 at the high-level transmission area 2. An annular sliding groove is opened inside the first limiting base 7. The arm rod 4 is limited and slides in the sliding groove of the first limiting base 7 through a shaft. A carton guiding and pushing plate 5 is fixedly connected to the arm rod 4. A pressing and stacking mechanism 6 is provided on the transportation base 1. By setting the pressing and stacking mechanism 6 to drive the carton guiding and pushing plate 5 on the arm rod 4 to automatically unload the carton boards on the high-level transmission area 2, the carton boards are stacked in sequence from top to bottom. During the stacking process, the pressing and stacking mechanism 6 stably limits the carton boards and guides and presses the carton boards being stacked at the same time, so that the carton boards are stacked in a regular manner, achieving the effect of automatic stacking. The carton boards are stacked in sequence and by pressing down, and there will be no problem that the carton boards are stuck and affect the stacking, achieving the effect of anti-jamming and high-stability stacking.

[0025] In this embodiment, the pressing and stacking mechanism 6 includes a stacking base 61 fixedly connected to the transportation base 1, an electric push rod 62 installed on the transportation base 1, and a guiding and pressing device 68 arranged on the stacking base 61. The output shaft of the electric push rod 62 is detachably and fixedly connected with a pushing plate 63. The surface of the pushing plate 63 slides inside the stacking base 61. The stacking base 61 is detachably installed with a driving motor 64 through bolts. The output shaft of the driving motor 64 is connected with a connecting rod 65. The end face of the connecting rod 65 is rotatably connected inside the stacking base 61. One end of the connecting rod 65 far from the driving motor 64 is fixedly connected with a driving frame 66. A sliding shaft 67 is limited to slide in the driving frame 66 through a linear sliding groove opened inside. The end face of the sliding shaft 67 is fixedly connected with the inside of the arm rod 4. And the end of the sliding shaft 67 penetrates through the arm rod 4 and is slidably connected with a second limiting base 69. The bottom of the second limiting base 69 is fixed on the stacking base 61. The second limiting base 69 has the same shape as the first limiting base 7. Through the limitation of the two limiting bases and the sliding grooves on them, not only can the movement of the carton guiding push plate 5 along the shape of its sliding groove be controlled, but also the carton guiding push plate 5 can be ensured to be always perpendicular to the plane of the high-level conveying area 2, so as to facilitate the blanking work of the carton board on the high-level conveying area 2 by the carton guiding push plate 5.

[0026] Furthermore, the guiding and pressing device 68 includes a pressing rod 681, a pressing plate 682, and two symmetrically distributed bottom supporting plates 683. One end of the pressing rod 681 is fixed on the surface of the connecting rod 65. The other end of the pressing rod 681 is used for pressing the pressing plate 682. The surface of the pressing plate 682 is elastically connected to the stacking base 61 through a spring. A magnetic repulsion base 685 is fixedly connected to the pressing plate 682. Magnetically repelled plates 684 are fixedly connected to both of the two bottom supporting plates 683. Magnets are arranged on both the magnetic repulsion base 685 and the two magnetically repelled plates 684. When the magnetic repulsion base 685 and the two magnetically repelled plates 684 are aligned in height, repulsion is generated according to the distribution of the magnet polarities at both ends of the magnets on the two magnetically repelled plates 684 and the magnet on the magnetic repulsion base 685. That is, in this state, the positive pole of the magnet on the magnetic repulsion base 685 corresponds to the positive pole of the magnet in one of the two magnetically repelled plates 684, and the negative pole of the magnet on the magnetic repulsion base 685 corresponds to the negative pole of the magnet in the other of the two magnetically repelled plates 684.

[0027] Even further, the surfaces of the pressing plate 682 and the magnetic repulsion base 685 are respectively slidably connected inside the stacking base 61. The two bottom supporting plates 683 are slidably connected inside the stacking base 61, and springs are connected between the surfaces of the two bottom supporting plates 683 and the stacking base 61.

[0028] On one side of the stacking base 61 away from the pushing plate 63, two connecting seats 610 are symmetrically installed. Inside both of the two connecting seats 610, side baffles 611 are elastically connected by torsion springs. The elastic force of the torsion springs provides a temporary fixing force and a reset driving force for the side baffles 611 after movement. On both sides of the pushing plate 63, top plates 612 are fixedly connected. The top plates 612 are in contact with the side baffles 611. During the pushing process, the pushing plate 63 can drive the side baffles 611 to rotate for yielding through the top plates 612, thereby realizing the effect of positioning the carton board during stacking and not interfering with the blanking of the carton board after stacking.

[0029] When the packaging carton guiding and stacking device of the present utility model is in use, the folded carton board is conveyed through the high-level conveying area 2 on the conveying base 1. During the intermittent conveying, the output shaft of the driving motor 64 drives the driving frame 66 to rotate through the connecting rod 65. During the rotation, the upper arm of the sliding shaft 67 drives the carton guiding and pushing plate 5 to move. The movement track of the carton guiding and pushing plate 5 is restricted by the limiting base one 7 and the limiting base two 69, and moves along the chute with the shape of the transmission track of the conveyor belt thereon. As Figure 3 described, the chute is provided with a high-level sliding area and a low-level sliding area. It is set that Figure 3 the state of the middle arm 4 is the initial state. At this time, the sliding shaft 67 on the arm 4 is located in the high-level sliding area of the chute. The rotation of the connecting rod 65 drives the upper arm of the sliding shaft 67 on the arm 4 to slide from the high-level sliding area to the low-level sliding area through the driving frame 66. During the sliding, the arm 4 drives the carton guiding and pushing plate 5 to push the carton board on the high-level conveying area 2. The carton board is forced to move towards the bottom supporting plate 683, realizing the effect of automatically blanking the carton board from the high-level conveying area 2. After the carton board is blanked onto the bottom supporting plate 683, the continuously rotating driving frame 66 drives the sliding shaft 67 to slide towards the high-level sliding area of the chute. During this sliding, the carton guiding and pushing plate 5 no longer contacts the carton board. The carton board is initially positioned on the two bottom supporting plates 683. At this time, the connecting rod 65 will rotate downward through the pressing rod 681 to squeeze the lower pressing plate 682. During the downward movement of the lower pressing plate 682, the magnetic repulsion base 685 thereon gradually aligns with the magnetic repulsion plate 684. After alignment, the magnetic repulsion base 685 generates a repulsive force to drive the bottom supporting plates 683 on the two magnetic repulsion plates 684 to move away from each other. During the moving away, the two bottom supporting plates 683 gradually lose the supporting effect on the carton board. The carton board without support is further pressed by the lower pressing plate 682 during the downward pressing to complete the downward stacking work. During the downward stacking, the carton board is always affected by the positioning of the inner wall of the stacking base 61, the two side baffles 611 and the pushing plate 63, and is stacked regularly. By continuously supplying carton boards through the high-level conveying area 2 and combining the guiding and pressing device 68 to press each carton board in sequence and downward, the effect of automatically stacking the carton boards is realized. Moreover, during the stacking, there will be no problem that the carton board is stuck and affects the stacking. At the same time, the stability of the carton board during the stacking is high, achieving the effect of anti-blocking and high-stability stacking.

[0030] During the stacking of carton boards, the electric push rod 62 is regularly controlled to work. The output shaft of the electric push rod 62 drives the pushing plate 63 to push out the stacked carton boards in the stacking base 61. After the pushing, the effect of automatically and quantitatively discharging the stacked carton boards is achieved. During the pushing, the pushing plate 63 can drive the side baffle 611 to rotate for yielding through the top plate 612, thereby realizing the effect of positioning the carton boards by the side baffle 611 during stacking and not interfering with the discharging of the carton boards after stacking.
