[0002] On packaging production lines, cardboard boxes often need to be flipped to accommodate different packaging processes, such as labeling, sealing, or multi-sided printing. Traditional cardboard box flipping devices typically employ complex robotic arms or vacuum suction mechanisms. These devices are not only bulky and expensive but also difficult to maintain. Furthermore, some simple flipping devices are prone to damaging the boxes or failing to flip them completely during the flipping process, affecting production efficiency and product quality. Especially for lightweight or irregularly shaped cardboard boxes, existing flipping devices often struggle to provide a stable and reliable flipping effect. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a packaging carton flipping device that solves the problems of complex structure, high cost, easy damage to the carton, and unstable flipping in existing carton flipping devices, thereby achieving efficient, stable, and low-cost 90° flipping of the carton.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A packaging carton flipping device, comprising:

[0006] The first conveyor belt, horizontally positioned, is used to transport incoming paper boxes;

[0007] The second conveyor belt is horizontally offset from the first conveyor belt and located in front of the conveying direction of the first conveyor belt, and the conveying direction of the second conveyor belt is perpendicular to the conveying direction of the first conveyor belt.

[0008] The baffle is set parallel to the conveying direction of the first conveyor belt and located below the cardboard box. Its position is relative to the vertical center axis of the cardboard box and biased towards the rear of the moving direction of the second conveyor belt, but does not leave the shadow coverage area of ​​the cardboard box.

[0009] Furthermore, the axle is covered with a first soft rubber for cushioning.

[0010] Furthermore, a limiting plate is fixedly connected to the end of the stop shaft to prevent the cardboard box from falling outside the second conveyor belt.

[0011] Furthermore, the stop shaft is rotatably mounted on the base of the first conveyor belt, and the stop shaft is connected to a drive device.

[0012] Furthermore, the driving device is a servo motor, and a baffle is fixedly connected to the baffle shaft. After the baffle is connected to the paper box, the servo motor drives the baffle to rotate in the direction of the second conveyor belt.

[0013] Furthermore, the baffles are provided in 1 to 3 units. When there are 2 units, the baffles are arranged in a straight line. When there are 3 units, the baffles are arranged in a ring.

[0014] Furthermore, the baffle is covered with a second soft rubber for cushioning.

[0015] Furthermore, the first conveyor belt is designed to be tilted out.

[0016] Furthermore, the upper belts of the first and second conveyor belts are provided with a plurality of parallel-arranged soft rubber tubes for supporting the upper belts.

[0017] Furthermore, the conveyor belts of both the first and second conveyor belts are made of soft plastic.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The system utilizes a simple mechanical structure to achieve a 90° flip of the cardboard box, eliminating the need for a complex control system or power unit, thus significantly reducing equipment costs and maintenance difficulty. The special positioning of the guide shafts allows the cardboard box to flip naturally and stably during transport, avoiding excessive squeezing or collision and effectively reducing the damage rate. The staggered first and second conveyor belts, along with the rationally arranged guide shafts, ensure the smoothness and efficiency of the flipping process, improving the overall efficiency of the packaging production line.

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0025] like Figures 1-2As shown, this utility model embodiment proposes a packaging carton flipping device, wherein the first conveyor belt 1 is horizontally arranged for conveying incoming cartons;

[0026] The second conveyor belt 2 is horizontally offset from the first conveyor belt 1 and located in front of the conveying direction of the first conveyor belt 1. The conveying direction of the second conveyor belt 2 is perpendicular to the conveying direction of the first conveyor belt 1.

[0027] The baffle 3 is set parallel to the conveying direction of the first conveyor belt 1 and located below the paper box. Its position is relative to the vertical center axis of the paper box and biased towards the rear of the moving direction of the second conveyor belt 2, but does not leave the shadow coverage area of ​​the paper box.

[0028] The first conveyor belt 1 is a 200mm wide modular plastic conveyor belt, driven by a 0.75kW three-phase asynchronous motor, with a conveying speed adjustable from 5-20m / min. The second conveyor belt 2 is offset from the first conveyor belt 1, with a vertical distance of 150mm between them. The second conveyor belt 2 is also a modular plastic conveyor belt, 250mm wide, driven by a 1.1kW three-phase asynchronous motor. The stop shaft 3 is a 30mm diameter stainless steel shaft, covered with a 5mm thick nitrile rubber first soft rubber 4. Its position is offset 30mm behind the vertical center axis of the cardboard box in the direction of movement of the second conveyor belt 2, without leaving the shadow coverage area of ​​the cardboard box. When the cardboard box is conveyed to the position of the stop shaft 3 along the first conveyor belt 1, the bottom of the cardboard box is blocked by the stop shaft 3, while the top continues to move forward under inertia, causing the cardboard box to rotate 90° around the stop shaft 3 and fall onto the second conveyor belt 2, achieving efficient rotation of the cardboard box.

[0029] The first soft rubber 4 covering the retaining shaft 3 is made of nitrile rubber with a Shore hardness of 60A and a thickness of 5mm. This soft rubber has good elasticity and abrasion resistance, effectively cushioning the impact between the cardboard box and the retaining shaft 3, preventing scratches or indentations on the cardboard box surface during flipping, and also reducing friction between the retaining shaft 3 and the cardboard box, ensuring smooth flipping. This cushioning design further improves the flipping quality of the cardboard box and reduces the product damage rate.

[0030] In this embodiment, as Figure 2 As shown, a 10mm thick Q235 steel plate is fixedly connected to the end of the stop shaft 3 as a limiting plate 5. The limiting plate 5 is 80mm high and 50mm wider than the width of the cardboard box. This limiting plate 5 can effectively prevent the cardboard box from falling off the second conveyor belt 2 due to excessive inertia during the flipping process, ensuring that all cardboard boxes can fall accurately onto the second conveyor belt 2, improving the reliability and stability of the device, reducing the need for manual intervention, and increasing production efficiency.

[0031] In this embodiment, as Figure 1 , 2 As shown, the stop shaft 3 is rotatably mounted on the base of the first conveyor belt 1 via two mounted spherical roller bearings, the bearing model being UCFL205. One end of the stop shaft 3 is connected to the output shaft of a 0.55kW servo motor via a coupling; the servo motor is a Panasonic MINASA6 series. This rotatable mounting method allows the stop shaft 3 to achieve precise angle control under the drive of the servo motor, providing a foundation for subsequent use of the baffle 7 to assist in the flipping of the cardboard box, and also facilitating the installation and maintenance of the device.

[0032] Among them, such as Figure 1 As shown, an aluminum alloy baffle 7 with a thickness of 15mm is fixedly connected to the baffle shaft 3. The baffle 7 has a width of 180mm and a height of 20mm. When the baffle 7 receives the cardboard box, the servo motor drives the baffle 7 to rotate towards the second conveyor belt 2 at an appropriate angular velocity, assisting the cardboard box in completing the flipping action. This active driving method allows for more precise control of the cardboard box flipping process.

[0033] Among them, such as Figure 2 As shown, depending on different production needs, the baffles 7 can be set to 1-3. When set to 2, the two baffles 7 are arranged in a straight line along the axis of the baffle shaft 3 with a spacing of 80mm; when set to 3, the three baffles 7 are arranged in a 120° ring on the baffle shaft 3. In this embodiment, for a standard cardboard box with dimensions of 200mm×150mm×100mm, 3 baffles 7 are preferably set. This design allows for reasonable adjustment of the number of baffles 7 according to the size and weight of the cardboard box to provide the best flipping assistance effect, ensuring efficient completion of the cardboard box flipping task under different working conditions.

[0034] Among them, such as Figure 1 As shown, the surface of the baffle 7 is covered with a 3mm thick layer of silicone second soft rubber 8 with a Shore hardness of 50A. This soft rubber layer not only buffers the impact force between the cardboard box and the baffle 7, protecting the surface of the cardboard box from damage, but also increases the friction between the baffle 7 and the cardboard box, ensuring that the baffle 7 can effectively drive the cardboard box to flip during rotation, thus improving the stability and reliability of the flipping.

[0035] In this embodiment, as Figure 2 As shown, the first conveyor belt 1 adopts a pick-out setting with a pick-out length of 100mm. This design allows the cardboard box to make fuller contact with the stop shaft 3 when it is conveyed to the stop shaft 3, ensuring that the bottom of the cardboard box is effectively blocked by the stop shaft 3, creating more favorable conditions for the smooth flipping of the cardboard box. In particular, for some shorter cardboard boxes, the pick-out setting can significantly improve their flipping success rate.

[0036] In this embodiment, as Figure 1 , 2As shown, several parallel-arranged flexible rubber cylinders 9 are installed below the upper belts of both the first conveyor belt 1 and the second conveyor belt 2 as supports. The flexible rubber cylinders 9 are made of nitrile rubber, with an outer diameter of 60mm, a length equal to the width of the conveyor belt, and a Shore hardness of 70A. These flexible rubber cylinders 9 effectively support the conveyor belts, reduce deformation when carrying cardboard boxes, ensure smooth operation, and absorb vibrations generated during conveying, reducing noise and improving the operational stability and service life of the device.

[0037] In this embodiment, both the first conveyor belt 1 and the second conveyor belt 2 are made of 2mm thick polyurethane soft plastic belts. This material has good flexibility and wear resistance, and can adapt to frequent bending and friction of the conveyor belt, extending its service life. At the same time, the smooth surface of the soft plastic belt can reduce the friction between it and the cardboard box, which is conducive to the smooth conveying and flipping of the cardboard box, improving the working efficiency and reliability of the entire device.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
