It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0027] like Figures 1 to 3 As shown, in this embodiment, the film box unloading device includes: a conveyor belt 10, a stop structure 20 and a accommodating structure 30. The conveyor belt 10 is used to transport the film boxes. The stop structure 20 is arranged on the conveyor belt 10, and the stop structure 20 includes a stop block 21, which cooperates with the upper edge of the film box. The accommodating structure 30 is arranged downstream of the conveyor belt 10, and the accommodating structure 30 includes a support base 31 and a support frame 32. The support base 31 is located at the bottom of the support frame 32, and the support frame 32 is arranged at an angle. The support base 31 and the support frame 32 jointly support the film box. Among them, when the conveyor belt 10 is started, it can drive the bottom of the film box to move forward, so that the film box passes the stop block 21 and enters the accommodating structure 30.

[0028] Using the technical solution of this embodiment, the conveyor belt 10 is used to transport film boxes. A stop structure 20 is provided on the conveyor belt 10. The stop structure 20 includes a stop block 21. The stop block 21 cooperates with the upper edge of the film box to stop. A accommodating structure 30 is provided downstream of the conveyor belt 10. The accommodating structure 30 includes a support base 31 and a support frame 32. The support base 31 is located at the bottom of the support frame 32. The support frame 32 is arranged at an angle. The support base 31 and the support frame 32 can jointly support the film box. Specifically, when the conveyor belt 10 is started, it can drive the film box forward, thereby allowing the film box to pass the stop block 21 and enter the accommodating structure 30. Through the above-mentioned arrangement, the stop structure 20 can prevent too many film boxes from entering the accommodating structure 30, thereby ensuring that there are fewer film boxes in the accommodating structure 30. Specifically, the bottom of the film box in the storage structure 30 cooperates with the bottom stop of the film box on the conveyor belt 10. When the film box on the storage structure 30 is removed, a gap is left between the bottom of the film box on the storage structure 30 and the bottom of the film box on the conveyor belt 10, thereby allowing the film box on the conveyor belt 10 to move forward and the top of the film box to pass over the stop block 21 and enter the storage structure 30. Therefore, the technical solution of this embodiment effectively solves the problem of excessive accumulation of film boxes in the related art, which affects the efficiency of box folding.

[0029] like Figures 1 to 5 As shown, in this embodiment, the stop structure 20 further includes a mounting frame 22, which is disposed on the conveyor belt 10, and a stop block 21 is disposed on top of the mounting frame 22. This structural design allows the stop block 21 to be securely fixed above the conveyor belt 10, ensuring accurate stopping of the film box even at high speeds, thereby preventing the film box from being misaligned due to unstable stops.

[0030] like Figure 1 、 Figure 2 、 Figure 4 as well as Figure 5 As shown, in this embodiment, the addition of mounting bracket 22 not only enhances the stability of stop block 21 but also facilitates adjustment of its position, allowing the device to accommodate film boxes of varying sizes and shapes. When handling larger film boxes, the robust stop structure 20 effectively prevents the boxes from shifting or tipping over during high-speed movement, ensuring safe transport of the boxes.

[0031] like Figure 1 、 Figure 2 、 Figure 4 as well as Figure 5As shown, in this embodiment, the stop structure 20 further includes an adjustment member 23, which is mounted on the mounting bracket 22. The stop block 21 is mounted on the adjustment member 23. The adjustment member 23 is capable of adjusting the distance between the stop block 21 and the conveyor belt 10. This design provides the device with a high degree of flexibility, allowing the position of the stop block 21 to be adjusted according to film boxes of different sizes, ensuring that each film box can be accurately stopped and discharged. This design is particularly suitable for production lines that need to process film boxes of various specifications, reducing downtime for adjustments due to changing film box specifications, and improving the continuity and efficiency of the production line.

[0032] like Figure 1 、 Figure 2 、 Figure 4 as well as Figure 5 As shown, in this embodiment, the presence of the adjustment member 23 enables the film box unloading device to quickly adapt to changes on the production line without the need for frequent shutdown adjustments, greatly shortening the adjustment time of the production line. In the field of electronic product packaging, due to the rapid replacement of products, packaging specifications often change. The use of the device in this application can quickly adjust to the new film box specifications, avoiding production line stagnation caused by specification changes, ensuring the synchronization of packaging speed and product update speed, and meeting the market's demand for rapid response. In addition, the design of the adjustment member also simplifies the operating process. The operator only needs to simply adjust the adjustment member to complete the replacement of the film box specifications, reducing the difficulty of operation and improving operational efficiency.

[0033] like Figure 1 、 Figure 2 、 Figure 4 as well as Figure 5 As shown, in this embodiment, the stop block 21 is located between the conveyor belt 10 and the receiving structure 30. This layout allows for a smooth transition of the film boxes during unloading, avoiding collisions or jams of the film boxes caused by improper positioning of the stop block 21. This is suitable for larger and heavier film boxes, ensuring safety and smoothness of the unloading process.

[0034] like Figure 1 、 Figure 2 、 Figure 4 as well as Figure 5 As shown, in this embodiment, the position of the stop block 21 is precisely set between the conveyor belt 10 and the containing structure 30 , which can effectively stop the film box without hindering the film box from entering the containing structure 30 .

[0035] like Figure 1 、 Figure 2 、 Figure 4 as well as Figure 5As shown, in this embodiment, the stop block 21 is cylindrical, and the axis of the cylinder is arranged parallel to the surface of the conveyor belt 10. The cylindrical stop block 21 design can reduce friction when contacting the film box, making it easier for the film box to pass over the stop block. This is suitable for use in situations where the film box surface is relatively smooth or has a special coating, reducing wear on the film box surface and protecting the quality of the film box.

[0036] like Figure 1 、 Figure 2 、 Figure 4 as well as Figure 5 As shown, in this embodiment, the design of the cylindrical stop block 21 takes into account the particularity of the film box surface, reduces friction, ensures the smooth movement of the film box, and protects the coating or pattern on the film box surface.

[0037] like Figure 1 、 Figure 2 、 Figure 4 as well as Figure 5 As shown, in this embodiment, the support base 31 is provided with an inclined surface 311. The distance between the inclined surface 311 and the upper surface of the conveyor belt 10 gradually increases from upstream to downstream of the conveyor belt 10. The design of the inclined surface 311 guides the film box to slide smoothly into the accommodating structure 30, avoiding the jamming caused by the excessive contact surface between the film box and the support base 31. This is particularly suitable for production lines where film boxes need to be quickly transferred to the next process after unloading, thereby improving the continuity and efficiency of the production line.

[0038] like Figure 1 、 Figure 2 、 Figure 4 as well as Figure 5 As shown, in this embodiment, the design of the inclined portion 311 is an innovative feature of this application. It can effectively guide the film box into the containing structure 30. Especially when the film box needs to pass through the unloading point quickly, this design can significantly increase the unloading speed, reduce the risk of the film box getting stuck or blocked, and ensure the continuous operation of the production line. On the automated packaging line of the express logistics center, a fast unloading speed is the key to improving overall logistics efficiency. Using the design of this application can accelerate the flow of film boxes and improve the processing capacity of the logistics center.

[0039] like Figure 1 、 Figure 2 、 Figure 4 as well as Figure 5 As shown, in this embodiment, the bevel portion 311 is smoothly configured. The smooth bevel portion 311 can further reduce friction when the film box slides, ensuring stability and smoothness of the film box during unloading. This is suitable for situations where the film box is heavy and the unloading speed is fast, reducing the risk of the film box being stuck or damaged due to excessive friction, and protecting the quality of the film box.

[0040] like Figure 1 、 Figure 2 、 Figure 4 as well as Figure 5 As shown, in this embodiment, the provision of a smooth beveled portion 311 is a key factor in improving the efficiency and quality of film box unloading. When handling heavy film boxes, the smooth surface reduces friction between the film box and the support base, preventing the film box from jamming or damage due to excessive friction, and ensuring the integrity and aesthetics of the film box during high-speed unloading.

[0041] like Figures 1 to 3 As shown, in this embodiment, the support frame 32 includes a frame 321 and a plurality of protrusions 322 disposed on the frame 321. The plurality of protrusions 322 are disposed at intervals on the frame 321, and the protrusions 322 are disposed protruding toward the interior of the frame 321. The design of the protrusions 322 provides additional support points during the unloading of film boxes, ensuring that the film boxes slide stably on the inclined support frame 32. This is suitable for film boxes of varying sizes and shapes, thereby improving the versatility and adaptability of the device.

[0042] like Figures 1 to 3 As shown, in this embodiment, the protrusions 322 are provided to address the instability issues caused by irregular film box sizes and shapes. By providing multiple support points, the film box remains stable even on the tilted support frame 32, preventing it from tipping over or shifting during unloading. When handling irregularly shaped film boxes, such as those used in the packaging of electronic products, this design ensures a smooth transition, avoiding production line interruptions or product damage caused by unstable film boxes, improving packaging accuracy and speed, and reducing production costs.

[0043] like Figures 1 to 3 As shown, in this embodiment, the film box unloading device also includes a material retrieving structure, which is located below the containing structure 30 and can retrieve materials from the containing structure 30. This design allows the unloaded film boxes to be automatically removed and folded into cartons without manual intervention, further improving the automation level of the production line. It is suitable for production environments that require continuous and rapid processing of large numbers of film boxes, such as food packaging, pharmaceutical packaging, and electronic product packaging. It can significantly improve production efficiency and reduce labor costs.

[0044] The addition of an automatic material-retrieving structure is another highlight of the design of this application. It can seamlessly connect to the sheet box after unloading, realizing continuous automated operation from unloading to retrieving, greatly reducing the burden on operators and improving production efficiency. In the food packaging industry, packaging speed directly affects the freshness and market competitiveness of food. The sheet box unloading device in this application can quickly process and ensure the timeliness and efficiency of food packaging, reduce food losses caused by packaging delays, and enhance the market competitiveness of food. In addition, the automated production line also reduces dependence on manpower, reduces production costs, and improves the economic benefits of the enterprise.

[0045] The film box unloading device of the present application realizes automatic unloading of film boxes through the ingenious design of the conveyor belt 10, the stop structure 20, and the containing structure 30. This not only improves the automation level of the production line, but also effectively avoids the safety risks and inefficiencies that may be caused by manual unloading. The provision of the stop structure 20 and the adjustment member 23 enables the device to adapt to film boxes of different sizes, enhancing the versatility and flexibility of the equipment. The design of the inclined portion 311 and the protrusion 322 further ensures the stability and smoothness of the film box during the unloading process, reduces the risk of box jamming and damage, and thus improves overall production efficiency and product quality.

[0046] According to another aspect of the present application, a folding box production line is provided. The folding box production line of this embodiment includes a sheet box unloading device, and the sheet box unloading device is the sheet box unloading device mentioned above. By adopting the sheet box unloading device of the present application, the production line can achieve fully automated operations from sheet box transportation, stopping, unloading to material retrieval, which not only improves production efficiency and reduces production costs, but also effectively avoids the safety risks that may be caused by manual operation, providing the packaging industry with a safer, more efficient and intelligent production solution. In addition, the high versatility and flexibility of the device enable it to easily handle sheet boxes of different specifications and materials, meeting the diversified and personalized needs of modern production lines, and is an important driving force for the automation upgrade of the packaging industry.

[0047] The automation upgrade of the folding box production line is the current development trend of the packaging industry. The sheet box unloading device in this application is a key link in the production line. Its efficient, safe and universal design can significantly improve the overall performance of the production line.
