[0002] Corrugated cardboard is a multi-layer adhesive body, which is composed of at least one layer of corrugated core paper interlayer and one layer of cardboard. It has high mechanical strength and can withstand collisions and drops during handling. The actual performance of corrugated cardboard depends on three factors: the characteristics of the core paper and cardboard, and the structure of the carton itself.

[0003] As the most commonly used material for commodity packaging at present, various information such as the specifications and trademarks of corresponding commodities are printed on corrugated cardboard. Most of the cardboard is single-sided printed. For some uses of cardboard, double-sided printing is required. During the double-sided printing process of cardboard, the cardboard needs to be turned over. When manually turning over the cardboard, the contact area between the worker and the cardboard is small, and the cardboard is easily deformed, affecting the quality of the product. Therefore, in view of the above problems, a cardboard turning device with the function of preventing cardboard from being clamped and damaged is proposed. Content of the Utility Model

[0022] Embodiment

[0023] As Figures 1-4As shown in the figure, a cardboard flipping device with the function of preventing cardboard from being pinched includes a conveyor 1 and a base 2. There are two bases 2. At the top ends of the two bases 2, support plates 3 are fixedly connected. At one end of one of the support plates 3, a first motor 4 is fixedly connected. At the end of the main shaft of the first motor 4, a rotating shaft 18 is fixedly connected, and the rotating shaft 18 is rotatably connected to the support plate 3. At one end of the other support plate 3, a rotary joint 6 is fixedly connected. (The rotary joint 6 is a prior art and will not be elaborated here). The rotary joint 6 includes a fixed part and a rotating part. The rotating part of the rotary joint 6 and the other end of the rotating shaft 18 are both fixedly connected with fixing plates 5. On the upper and lower sides of the horizontal center line at one end of the fixing plate 5, fixing frames 14 are fixedly connected. Inside the two fixing frames 14, a clamping mechanism and a conveying mechanism are respectively arranged. On both sides of the fixing frame 14, conveyors 1 are arranged. At one end of one of the support plates 3, a controller 17 is fixedly connected.

[0024] As a further improvement of the present invention, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, the clamping mechanism includes a limiting plate 15 fixedly connected to the fixing frame 14, and the limiting plate 15 is fixedly connected to the connecting plate 13. At one end of the limiting plate 15, an airbag 16 is fixedly connected. The upper and lower airbags 16 are arranged oppositely. One side of the airbag 16 is provided with a ventilation component. After the upper and lower airbags 16 expand, they will clamp the cardboard. Since the airbag 16 is in flexible clamping with the cardboard after expansion, it is ensured that the airbag 16 will not pinch the cardboard, thus realizing the protection of the cardboard. At the same time, the first motor 4 can drive the upper and lower fixing frames 14 to flip 180 degrees through the fixing plate 5, thus realizing the flipping of the cardboard.

[0025] As a further improvement of the present invention, as shown in Figure 1 , Figure 2 shown, one end of the airbag 16 is communicated with an air pipe 7, and the air pipe 7 is communicated with the rotating part of the rotary joint 6. The fixed part of the rotary joint 6 is communicated with an air delivery pipe 9. The other end of the air delivery pipe 9 is communicated with an air pump 8, and the air pump 8 is fixedly connected to the base 2. The air pump 8 injects gas into the inside of the airbag 16 through the air delivery pipe 9, the rotary joint 6, and the air pipe 7, so that the airbag 16 expands.

[0026] As a further improvement of the present invention, as shown in Figure 2 , Figure 3 and Figure 4 shown, the contact surface of the inflated airbag 16 with the cardboard protrudes from the end face of the fixing frame 14, ensuring that the airbag 16 can normally clamp the cardboard.

[0027] As a further improvement of the present utility model, as Figure 2 , Figure 3 shown, the conveying mechanism includes a roller 11 rotatably connected to both the fixed frame 14 and the connecting plate 13. A belt 12 is arranged on the outer side of the roller 11. Both ends of each fixed frame 14 are fixedly connected with a second motor 10, and the end of the main shaft of each second motor 10 is fixedly connected with the corresponding roller 11. After the cardboard is flipped by 180 degrees, the gas inside the airbag 16 is pumped out, and then the second motor 10 drives the belt 12 to rotate through the roller 11, and the cardboard is transported to the surface of the next conveyor 1 through the belt 12.

[0028] Working process: First, the cardboard is conveyed by one of the conveyors 1 between two adjacent airbags 16. When the conveyor 1 conveys the cardboard between two adjacent airbags 16, the second motor 10 also drives the belt 12 to rotate through the roller 11, and the cardboard is transported between two adjacent airbags 16 with the assistance of the belt 12. After the cardboard is transported between two adjacent airbags 16, the second motor 10 is controlled to stop working. Then, the controller 17 controls the air pump 8 to work, so that the air pump 8 injects gas into the inside of the airbag 16 through the air pipe 9, the rotary joint 6, and the ventilation pipe 7, causing the airbag 16 to expand, thereby clamping the cardboard through the airbag 16. Since the airbag 16 is in flexible clamping with the cardboard after expansion, it is ensured that the airbag 16 will not damage the cardboard, thus realizing the protection of the cardboard. Then, the first motor 4 can drive the upper and lower fixed frames 14, the airbag 16, and the cardboard to flip by 180 degrees through the fixed plate 5, thereby realizing the flipping of the cardboard. Then, the second motor 10 starts working again, driving the belt 12 to rotate through the roller 11, and transporting the cardboard to the surface of the next conveyor 1 through the belt 12, and then the next round of work can be carried out; when the fixed frame 14 rotates, the fixed frame 14 also drives the rotating parts of the ventilation pipe 7 and the rotary joint 6 to rotate together, ensuring that the ventilation pipe 7 will not get entangled.
