[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] This embodiment is a paper box flatness testing device.

[0022] like Figure 1-4 As shown, the device includes a cardboard box 1, a conveying assembly 2 at the lower end of the cardboard box 1, a flatness tester 3 at the middle of the upper end of the conveying assembly 2, a control panel 4 on one outer surface of the flatness tester 3, and a feeding mechanism 5 at the front end of the outer surfaces on both sides of the conveying assembly 2. The feeding mechanism 5 includes a fixing plate 6, a fixing frame 7, a cylinder 8, a pump body 9, a suction cup 10, a connecting frame 11, a motor 12, a first rotating shaft 13 and a second rotating shaft 14. The fixing plate 6 is fixedly installed on the front end of one outer surface of the conveying assembly 2, and the two sets of fixing frames 7 are located at the front and rear ends of one side of the upper outer surface of the fixing plate 6, respectively.

[0023] The connecting frame 11 is located at the upper end between the two sets of fixed frames 7. The first rotating shaft 13 is located on the outer surface of the front end of the connecting frame 11, and the second rotating shaft 14 is located on the outer surface of the rear end of the connecting frame 11. The motor 12 is located at the front end of the first rotating shaft 13, the cylinder 8 is located in the middle of the connecting frame 11, the pump body 9 is located on the outer surface of one side of the cylinder 8, and the suction cup 10 is located on the outer surface of one side of the pump body 9. Sealed bearings are provided between the second rotating shaft 14, the first rotating shaft 13 and the fixed frame 7, and the second rotating shaft 14 and the first rotating shaft 13 are rotatably connected to the fixed frame 7 through the sealed bearings. The cylinder 8, the pump body 9 and the control panel 4 are electrically connected.

[0024] It should be noted that this utility model is a paper box flatness testing device. The paper box 1 is conveyed by the conveying component 2 and tested by the flatness tester 3. The flatness tester 3 transmits the data to the control panel 4. The control panel 4 controls two sets of cylinders 8 to push the pump body 9 to one side, move the suction cup 10 to both sides of the paper box 1, and limit the paper box 1. Then, one set of pump bodies 9 is started to attach the suction cup 10 to the paper box 1. The other set of cylinders 8 is started to drive the other set of non-started pump bodies 9 to one side. By starting the motor 12 on the side where the paper box 1 is attached, the first rotating shaft 13 is rotated, and the connecting frame 11 and the second rotating shaft 14 are rotated at the same time, thereby causing the paper box 1 to rotate 180 degrees, so as to unload the paper box 1. It can conveniently unload unqualified paper boxes 1, is simple to operate, reduces manual operation, and facilitates the limiting and adsorption of paper boxes 1.
