[0031] A paper shell bending device provided in this embodiment, refer toFigures 1 - 5 As shown in the figure, it includes a base 1. On the upper end surface of the base 1, there is a support plate 2. At the upper part of the support plate 2, there is a connecting rod 3. At the upper part of the connecting rod 3, there are two fixing rods 31. On the two fixing rods 31, a first upright post 311 and a second upright post 312 are respectively installed. Below the first upright post 311 and the second upright post 312, there is a guide panel 4. The bottom surfaces of the first upright post 311 and the second upright post 312 are close to the guide panel 4. On the side of the first upright post 311, there is a first bending plate 3111. On the guide panel 4 below the first bending plate 3111, there is a first air hole 41. On the side of the second upright post 312, there is a second bending plate 3121. On the guide panel 4 below the second bending plate 3121, there is a second air hole 42. On the side of the second upright post 312, there is a guide wheel 3122. On one side of the guide panel 4, there is a conveying device 5.
[0032] In the above embodiment, preferably, at the lower part of the device, there is a base 1. The base 1 is used to increase the contact area between the device and the ground, which is beneficial to improving the stability of the device during operation. At the upper part of the support plate 2, there is a connecting rod 3. At the upper part of the connecting rod 3, there are two fixing rods 31. On the two fixing rods 31, a first upright post 311 and a second upright post 312 are respectively installed. Below the first upright post 311 and the second upright post 312, there is a guide panel 4. The bottom surfaces of the first upright post 311 and the second upright post 312 are close to the guide panel 4. On the side of the first upright post 311, there is a first bending plate 3111. On the guide panel 4 below the first bending plate 3111, there is a first air hole 41. On the side of the second upright post 312, there is a second bending plate 3121. On the guide panel 4 below the second bending plate 3121, there is a second air hole 42. The air holes are communicated with an air pipe 411. The air pipe 411 is used to introduce gas into the air holes and form an upward air flow above the air holes. On one side of the guide panel 4, there is a conveying device 5. The conveying device 5 is used to drive the part of the cardboard that needs to be bent to move on the upper end surface of the guide panel 4. The guide panel 4 is used to provide support for the cardboard to prevent the cardboard from sagging and deforming due to its own gravity during the movement, which is beneficial to improving the flatness of the cardboard and preventing the cardboard from deforming and causing paper jams, thereby improving the bending efficiency of the cardboard. During the process of bending the cardboard, such as Figure 4As shown in the figure, the bent end of the paper shell abuts against the side surface of the first upright post 311. The abutting end of the paper shell is blown upward by the airflow of the first air hole 41. The air hole is connected to the air pipe 411, and the air pipe 411 is communicated with the air pump. The operating state of the air pump can be controlled and adjusted, and then the air output of the air hole can be controlled, which can be used to adapt to blowing up the bent ends of paper shells with different thicknesses, and can also prevent the paper shell from being blown away from the bending device due to excessive air flow velocity at the air hole. Driven by the conveying device 5, one end of the paper shell moves upward. When it encounters the bottom end of the first bending plate 3111, it is blocked. Driven by the conveying device 5, the upward moving end of the paper shell body will be folded under the squeezing action of the gap between the bottom surface of the first upright post 311 and the guide panel 4, and then a 180-degree folding and bending of one end of the paper shell is realized. Similarly, when the paper shell passes through the second upright post 312, it can be folded twice. Further, when the thickness of the paper board after the second folding increases, the folded paper board will elastically warp upward. The side surface of the second upright post 312 is connected with a guide wheel 3122. The guide wheel 3122 can roll and squeeze the folded paper shell again, which is beneficial to improving the flatness of the paper shell after bending. The bent paper shell can enter the subsequent paper box processing procedure. In summary, this device reduces the manual participation degree in the process of paper shell bending, can be applied to batch bending processing of paper shells, and is beneficial to improving the production efficiency of packaging boxes.
[0033] In an embodiment of the present application, refer to Figure 1 As shown in the figure, the conveying device 5 includes an upper conveyor belt 51 and a lower conveyor belt 52, and the upper conveyor belt 51 is close to the lower conveyor belt 52.
