DETAILED DESCRIPTION

The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

The paperboard correction mechanism includes a mounting frame 1, on which a single roller unit 2 and a double roller unit 3 are arranged, the single roller unit 2 is a roller, the double roller unit 3 includes a first conveying roller and a second conveying roller, the single roller unit 2 and the double roller unit 3 are arranged opposite to each other up and down (for example, the single roller unit 2 is above the double roller unit 3 or the double roller unit 3 is above the single roller unit 2); the single roller unit 2 is arranged centrally relative to the double roller unit 3, for example, the single roller unit 2 includes a first roller body, the double roller unit 3 includes a second roller body and a third roller body, and the first roller body is arranged centrally relative to the second roller body and the third roller body. The paper conveying speed of the single roller unit 2 is the same as that of the double roller unit 3, and there is a paperboard correction space 10 between the double roller units 3, the paperboard correction space 10 refers to the axial end of the double roller unit 3 close to the single roller unit 2 as the starting horizontal plane, the axis between the axis of the first conveying roller of the double roller unit 3 and the axis of the second conveying roller as the terminal horizontal plane, and the paperboard correction space 10 is between the starting horizontal plane and the terminal horizontal plane. The single roller unit 2 has a straightening surface, and the straightening surface of the single roller unit 2 is arranged in a cardboard straightening space 10 of the double roller unit 3 .

Working principle: the warping direction of the cardboard faces away from the single roller unit 2, and the single roller unit 2 and the double roller unit 3 cooperate to apply downward pressure to the cardboard that is warped upward, thereby correcting the cardboard. When the single roller unit 2 is below the double roller unit 3, as shown in Figure 2, the cardboard with both ends warped upward passes between the single roller unit 2 and the double roller unit 3, and the single roller unit 2 and the double roller unit 3 with the same linear speed straighten the warped cardboard; as shown in Figure 3, when the double roller unit 3 is below the single roller unit 2, the warping direction of the cardboard faces downward and enters between the single roller unit 2 and the double roller unit 3, thereby correcting the cardboard.

Furthermore, the single roller unit 2 and the double roller unit 3 are connected in transmission through a synchronization device 4, and the synchronization device 4 includes a synchronization power source 41. There are many ways for the single roller unit 2 and the double roller unit 3 to have the same transmission speed, for example, the synchronization power source 41 includes a first power source and a second power source, the first power source and the second power source have the same rotation speed, and the first power source drives the single roller unit 2 to rotate. Alternatively, there is one synchronization power source 41, and a transmission belt 42 is wound between the shaft end of the single roller unit 2 and the shaft end of the double roller unit 3. The transmission belt 42 can be a belt or a chain. The transmission belt 42 is connected in transmission with the synchronization power source 41, and the synchronization power source 41 has an active roller, which is rotatably arranged on the mounting frame 1, and the transmission belt 42 is wound around the single roller unit 2, the double roller unit 3 and the active roller, so that the single roller unit 2, the double roller unit 3 and the active roller rotate synchronously. The mounting frame has a tensioning wheel 5 with a left-right adjustment setting. There are various left-right adjustment methods. For example, as shown in FIG1 , the tensioning wheel 5 is rotatably set on an adjustment plate. A through slot is provided on the adjustment plate. The tensioning wheel 5 is fixed to the mounting frame 1 with bolts through the through slot. The position of the tensioning wheel 5 is adjusted by loosening or tightening the bolts, thereby adjusting the tension of the transmission belt 42.

The single roller unit 2 or double roller unit 3 arranged on the upper side is adjusted up and down on the mounting frame 1. In this embodiment, the mounting frame 1 is provided with an adjustment slot 6, and the adjustment slot 6 is provided with a moving block 7. The single roller unit 2 or double roller unit 3 (the roller unit on the upper side) is arranged on the moving block. According to the degree of upward warping of the cardboard or the specifications of the cardboard, the moving block 7 is moved up and down to drive the single roller unit 2 or double roller unit 3 arranged on the upper side to move up and down, wherein there are multiple ways for the moving block to move up and down. The moving block 7 is slidably arranged in the adjustment slot 6. The mounting frame 1 is provided with a lifting adjustment screw 8, and the moving block 7 is arranged on the lifting adjustment screw 8, that is, the moving block 7 is fixedly installed at the lower end of the lifting adjustment screw 8, and the upper and lower positions of the moving block 7 are adjusted by rotating the lifting adjustment screw 8. The nut cooperates with the lifting adjustment screw 8 to tighten the moving block 7, that is, fix the position of the moving block 7, thereby adjusting the position of the single roller unit 2 or double roller unit 3 on the upper side, which can adapt to the cardboard of corresponding specifications and can control the degree of correction of the cardboard. The single roller unit 2 or double roller unit 3 is rotatably arranged on the moving block 7. An elastic member 9 is connected between the lifting adjustment screw 8 and the moving block 7. The elastic member 9 may be a spring, which can strengthen the tightness of the fit between the nut and the lifting adjustment screw 8, and provide a certain buffer force to make the upper single roller unit 2 or double roller unit 3 more stable.
