[0002] Paper box printing refers to printing the required text, patterns and other information onto the surface of a paper box. It generally includes processes such as plate mounting, inking, printing and paper feeding. During the paper box printing process, multiple sides of the paper box need to be printed, and the paper box is flipped with the help of an auxiliary flipping mechanism.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figure 1 - Figure 5As shown, this utility model provides an auxiliary flipping mechanism for paper box printing, including a first conveyor belt 1, a stabilizing flipping mechanism 2 installed on one side of the first conveyor belt 1, a second conveyor belt 4 installed on one side of the stabilizing flipping mechanism 2, and a position adjustment mechanism 3 installed on one side of the second conveyor belt 4. The stabilizing flipping mechanism 2 includes a fixed plate 21, with its two ends fixedly connected to one end of the first conveyor belt 1 and one end of the second conveyor belt 4, respectively. A connecting plate 210 is fixedly connected to one side of the fixed plate 21, and two second rotating rods 29 are rotatably connected to one side of each of the two connecting plates 210. A support plate 28 is fixedly connected to one end of each of the two second rotating rods 29, and a moving plate 26 is provided between the two support plates 28. The moving plate 26 has the same structure as one of the support plates 28. A positioning plate 216 is fixedly connected to one side of the moving plate 26, and a first moving component 213 is installed on one side of the positioning plate 216. A second moving component 217 is provided on the other side of the positioning plate 216, and a conveyor belt 217 is installed at one end of the second moving component 217. A first rotating rod 27 is fixedly connected to the middle of a wheel 218, and both ends of the first rotating rod 27 are rotatably connected to one side of two support plates 28. A first conveying assembly 23 is installed at the other end of one of the second rotating rods 29, and a first motor 22 is installed at one end of the second rotating rod 29 through the first conveying assembly 23. One side of the first motor 22 is fixedly connected to one side of a connecting plate 210. A first gear 214 is installed at one end of a first moving assembly 213, and one end of the first gear 214 is rotatably connected to one side of a moving plate 26. A second gear 215 meshes with one side of the first gear 214, and one end of the second gear 215 is rotatably connected to one side of the moving plate 26. The other end of the second gear 215 is connected to a second moving assembly 217. A second motor 212 is fixedly connected to one side of a support plate 28, and a second conveying assembly 211 is installed at the output end of the second motor 212. The output end of the second motor 212 is connected to one end of the first rotating rod 27 through the second conveying assembly 211.

[0025] The cardboard box is conveyed to the stable flipping mechanism 2 via the first conveyor belt 1. Both ends of the cardboard box contact the two positioning plates 216. The first moving component 213 and the second moving component 217 clamp the two sides of the cardboard box respectively. The second motor 212 drives the first rotating rod 27 to rotate, causing the two conveyor wheels 218 to rotate, which in turn drives the second moving component 217. The meshing of the second gear 215 with the first gear 214 drives the first moving component 213. Both the second moving component 217 and the first moving component 213 are connected by guide pulleys and transmission belts. The conveyor belts on the first moving component 213 and the second moving component 217 transport the cardboard box to the middle position of the moving plate 26. The first motor 22 drives the two second rotating rods 29 to rotate, causing the moving plate 26 and the support plate 28 to flip, turning the cardboard box 180 degrees. Then the second motor 212 rotates in the opposite direction, driving the cardboard box to move to the second conveyor belt 4, moving the flipped cardboard box onto the second conveyor belt 4. During the flipping process of the cardboard box, the cardboard box can be limited, improving the flipping effect of the cardboard box and preventing slippage and misalignment during the flipping process.

[0026] Example 2: Figure 3 and Figure 5 As shown, a threaded rod 25 is threadedly connected to one side of the movable plate 26, and the two ends of the threaded rod 25 are rotatably connected to one side of the two support plates 28; a guide rod 24 is slidably connected to one side of the movable plate 26, and the end of the guide rod 24 is fixedly connected to one side of the support plate 28; the position adjustment mechanism 3 includes a first guide plate 31, one end of the first guide plate 31 is fixedly connected to one side of the second conveyor belt 4, an electric push rod 32 is rotatably connected to one side of the first guide plate 31, a fixed frame 34 is rotatably connected to one end of the electric push rod 32, a second guide plate 33 is fixedly connected to one side of the fixed frame 34, and one end of the fixed frame 34 is rotatably connected to one end of the first guide plate 31.

[0027] Before the stable flipping mechanism 2 receives the cardboard boxes from the first conveyor belt 1, the threaded rod 25 is rotated to drive the threaded movable plate 26 to move. The movable plate 26 slides outside the guide rod 24, and the fixed movable plate 26 makes linear motion. The movement of the movable plate 26 adjusts the distance between itself and the support plate 28, and fixes and flips cardboard boxes of different sizes. When the cardboard boxes are flipped and transported to the second conveyor belt 4, the electric push rod 32 works to push one side of the fixed frame 34 to move. The fixed frame 34 rotates at one end of the first guide plate 31, and at the same time, one end of the electric push rod 32 slides on the fixed frame 34. The tilt angle of the two fixed frames 34 can be adjusted, thereby centering and positioning the cardboard boxes flipped and placed on the second conveyor belt 4, reducing the need for subsequent adjustments to the position of the cardboard boxes and improving the conveying efficiency of the cardboard boxes.

[0028] The device is used and operates as follows: By rotating the threaded rod 25, the moving plate 26 is moved, and the distance between it and the support plate 28 is adjusted to fix different paper boxes. The paper box is transported to the stable flipping mechanism 2 by the first conveyor belt 1. The two ends of the paper box are in contact with the two positioning plates 216. The first moving component 213 and the second moving component 217 clamp the two sides of the paper box respectively. The second motor 212 drives the first rotating rod 27 to rotate, and the two conveying wheels 218 rotate, driving the second moving component 217 to move. The first moving component 213 moves accordingly, conveying the paper box to the middle position of the moving plate 26. The first motor 22 drives the two second rotating rods 29 to rotate, causing the moving plate 26 and the support plate 28 to flip, flipping the paper box 180 degrees. The flipped paper box is moved to the second conveyor belt 4. The electric push rod 32 pushes one side of the fixing frame 34 to move, adjusting the tilt angle of the two fixing frames 34 and centering the paper box.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
