[0029] The following is combined with Figure 1-3 This application is described in further detail.

[0030] The embodiment of the present application discloses a carton gluing device. Figure 1 The carton gluing device includes a finished product conveyor belt 1, a distribution conveyor belt 2, a distribution component 3, a pause component 4, a packaging platform 5 and a lifting component 6, wherein the distribution conveyor belt 2 is provided with a distribution conveyor belt 2 at the end away from the finished product conveyor belt 1, and the distribution conveyor belt 2 is provided with a distribution component 3, and a pause component 4 is provided between the finished product conveyor belt 1 and the distribution conveyor belt 2; two packaging platforms 5 are provided at the end of the distribution conveyor belt 2 away from the finished product conveyor belt 1, and a lifting component 6 is respectively provided between the two packaging platforms 5 and the ground, and the two packaging platforms 5 are arranged in sequence along the transmission direction perpendicular to the distribution conveyor belt 2.

[0031] With the distribution conveyor 2 and its distribution assembly 3, when a box on one distribution platform is filled with finished box-gluing products, the distribution assembly 3 directs the subsequent box-gluing products to empty boxes on other distribution platforms, significantly improving box packing efficiency. The design of the distribution assembly 3 ensures that the finished box-gluing products are accurately placed into the corresponding boxes, while the lifting assembly 6 allows the packaging platform 5 to complete height adjustment without manual intervention, further improving the degree of automation and work efficiency.

[0032] Reference Figure 2 The distribution assembly 3 includes a distribution motor 31 and a distribution screw 32. An extension plate is provided at the end of the distribution conveyor belt 2 away from the finished product conveyor belt 1. The distribution screw 32 is rotatably connected to the extension plate through a bearing. The distribution motor 31 is fixed to the extension plate by bolts. The shaft of the distribution motor 31 passes through the extension plate and is connected to the distribution screw 32. The distribution motor 31 rotates to drive the distribution screw 32 to rotate.

[0033] Two distribution blocks 33 are threadedly connected to the distribution screw 32, and the distance between the two distribution blocks 33 is equal to the length of each packaging platform 5; and the side walls of the two distribution blocks 33 are in contact with the side walls of the baffle 35. When the distribution screw 32 rotates, the distribution blocks 33 are in contact with the baffle 35 and cannot rotate, so the distribution blocks 33 can move along the length direction of the distribution screw 32.

[0034] The two distribution blocks 33 are provided with distribution elastic strips 34, which are folded elastic strips. The two distribution elastic strips 34 form a group of distribution elastic strips 34. One end of the distribution elastic strip 34 is fixed to the top of the distribution block 33 by gluing, and the other end is fixed to the finished product conveyor belt 1 through a connecting rod after passing through the distribution conveyor belt 2. The distribution elastic strip 34 is always in a stretched state; at this time, a channel for the pasted box products to pass through is formed between the two distribution elastic strips 34. Under the guidance of the direction of each distribution elastic strip 34, the pasted box products are finally transferred to the box on the corresponding packaging platform 5.

[0035] Reference Figure 2When the distribution block 33 moves along the distribution screw 32, it means that the boxes on a certain packaging platform 5 are full of finished box-gluing products, and the distribution elastic strip 34 is needed to guide the finished box-gluing products to the empty boxes on another packaging platform 5 for packing. At this time, the pause assembly 4 temporarily separates the finished product conveyor belt 1 and the distribution conveyor belt 2. The pause assembly 4 includes a pause rod 41 and a drive member 42. One end of the pause rod 41 is rotatably connected to the finished product conveyor belt 1 via a shaft, and the pause rod 41 is mounted on one side of the finished product conveyor belt 1. The drive member 42 includes a drive cylinder 422, which is mounted below the finished product conveyor belt 1 through a bracket and is located below the pause rod 41. A drive rope 421 is wound around the piston rod of the drive cylinder 422. The end of the drive rope 421, away from the drive cylinder 422, is connected to the pause rod 41 near the connection between the pause rod 41 and the finished product conveyor belt 1. The pause rod 41 is arranged between the distribution conveyor belt 2 and the finished product conveyor belt 1 and rotates around the connection point to briefly pause the finished box-gluing products on the finished product conveyor belt 1 when the distribution block 33 moves along the transmission direction perpendicular to the distribution conveyor belt 2.

[0036] A limiting pad 43 is embedded in the end of the finished product conveyor belt 1 away from the end connected to the pause rod 41 to protect the finished product conveyor belt 1.

[0037] Reference Figure 2 and Figure 3 In this embodiment, a notch is preset at one end of the box on the packaging platform 5 facing the distribution conveyor belt 2 for the finished glued box products to enter.

[0038] Reference Figure 1 and Figure 3 The lifting assembly 6 includes a plurality of lifting guide columns 61 and a plurality of lifting springs 62. Among them, the lifting guide columns 61 are installed on the ground to support the smooth up and down movement of the entire packaging platform 5. The packaging platform 5 is slidably set on the lifting guide columns 61, which can not only ensure the stable rise and fall of the platform, but also reduce the shaking caused by heavy loads. The lifting guide columns 61 can be made of stainless steel or carbon steel. This type of material has strong corrosion resistance and good load-bearing capacity, and can adapt to long-term and high-frequency use conditions. In order to enhance the stability of the guide column, a thickened support ring or reinforcement ribs can be added to its outside, so that it can maintain good straightness and stability even under heavy load conditions. In addition, in order to reduce the noise generated during operation, a suitable lubricant can be applied to the contact surface of the lifting guide column 61 or a shock-absorbing gasket can be installed.

[0039] The lifting spring 62 is located between the packaging platform 5 and the ground and is mounted on the lifting guide column 61. It provides both a cushioning function and a restoring function. For example, a spring wound from high-strength spring steel wire can be used, as this material has excellent elastic properties and fatigue resistance. Selecting the appropriate spring stiffness coefficient is crucial, as it directly affects the speed and smoothness of the packaging platform 5's lifting and lowering.

[0040] A distance sensor 51 is installed at the bottom of the packaging platform 5 to monitor the relative position of the platform to the ground in real time. A controller 52 is mounted on the sidewall of the finished product conveyor belt 1. Both the distance sensor 51 and the dispensing motor 31 are electrically connected to the controller 52. The controller 52 receives the height signal from the distance sensor 51 and controls the operation of the dispensing motor 31 accordingly, ensuring that each dispensing operation is completed accurately and flawlessly. Specifically, the distance sensor 51 transmits a distance signal indicating when the packaging platform 5 has reached its lowest point. The controller 52 receives this distance signal and controls the rotation of the dispensing motor 31, thereby controlling the dispensing block 33 to drive the dispensing elastic strip 34 to any packaging platform 5.

[0041] By replacing human judgment with digital management, errors caused by subjective factors are greatly avoided and operational accuracy is improved. Secondly, the intelligent control system makes operation more convenient, greatly reducing the burden on staff. Finally, since all actions are automatically adjusted based on data feedback, the entire process becomes more coherent and smooth, further accelerating the turnover rate of the production line.

[0042] To achieve this, we need to make some necessary modifications and improvements to the control algorithm. The traditional PID control method is still applicable here, but it needs to be used in conjunction with an adaptive parameter tuning strategy to achieve the best results. This not only supports basic proportional-integral-derivative functions, but also supports online learning, which means that various control parameters can be dynamically adjusted based on data collected under different operating conditions. In this way, no matter how the external environment changes, the system can always find the state that best suits its operation and continue to provide an efficient and reliable control experience.

[0043] The implementation principle of a carton gluing device according to an embodiment of the present application is as follows: When the gluing device is performing the pre-sequence operation, the finished gluing boxes are conveyed through the finished product conveyor belt 1. At this time, the pause rod 41 is in a vertical state, the finished product conveyor belt 1 is connected to the distribution conveyor belt 2, and the distribution block 33 is located at one of the packaging platforms 5. At this time, the distribution elastic strip 34 guides the finished gluing boxes transferred from the finished product conveyor belt 1 to the distribution conveyor belt 2 to the corresponding packaging platform 5. At this time, because the empty box inside the packaging platform 5 is relatively light, the packaging platform 5 rises to the highest point under the action of the lifting spring 62. At this time, the distribution elastic strip 34 is located at the lowest point of the notch of the box on the packaging platform 5. The finished gluing boxes slide into the bottom of the box along the distribution conveyor belt 2. Each time a finished gluing box slides into the box, the overall mass of the box increases, thereby exerting pressure on the lifting spring 62, thereby compressing the lifting spring 62, and the packaging platform 5 gradually descends. When the packaging platform 5 descends to the preset lowest point, it means that the box is full of finished gluing boxes. At this time, the distance sensor 51 sends a distance signal to control The device 52 receives the distance signal and controls the distribution motor 31 to rotate, so as to control the distribution block 33 to drive the distribution elastic strip 34 to the adjacent packaging platform 5 and load the finished glued box products into the new empty box. At the same time, the pause rod 41 is in a horizontal state to separate the finished product conveyor belt 1 and the distribution conveyor belt 2; the operator uses a forklift to move the box full of glued box products from the packaging platform 5 and replace it with a new empty box; because the movement speed of the distribution block 33 is only a few seconds, even if the pause rod 41 separates the finished product conveyor belt 1 and the distribution conveyor belt 2, the pause time is relatively short, which improves the degree of automation and work efficiency compared with manual box replacement and restart.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
