[0041] Combine the following Figures 1 to 3 The embodiments of the present utility model are described.

[0042] This embodiment relates to a rotary U-turn device, which realizes the turning of the cardboard pages and can ensure the conveying power of the cardboard pages.

[0043] The rotating U-turn device in this embodiment includes:

[0044] frame;

[0045] U-turn lifting drive 1;

[0046] U-turn rotation drive 2;

[0047] An upper reversing plate 3, arranged on the frame;

[0048] The lower reversing plate 4 is driven by the U-turn rotating driver 2 and the U-turn lifting driver 1 to move and rotate toward the upper reversing plate 3;

[0049] A driving roller 51, located beside the lower reversing plate 4;

[0050] The driving wheel 52 is drivingly connected to the driving roller 51 , and the driving wheel 52 is rotatably arranged on the frame.

[0051] The rotary U-turn device has a driving roller 51 driven by a driving wheel 52, which fills the gap between the conveyor belts formed by the lower reversing plate 4. The driving roller 51 provides assistance to the cardboard page, thereby improving the power of cardboard page transportation and ensuring the accuracy of cardboard page transportation.

[0052] In this embodiment, the U-turn lifting driver 1 is arranged on the frame, and the frame is also provided with a U-turn lifting slide, and a U-turn lifting slide rail 11 is slidably connected to the U-turn lifting slide, and the U-turn lifting slide rail 11 is connected to the U-turn rotation driver 2. The U-turn lifting driver 1 supports the U-turn rotation driver 2, and the U-turn rotation driver 2 can be supported by the U-turn lifting slider 12 and the U-turn lifting slide rail 11, so as to improve the accuracy of the lifting action of the U-turn lifting driver 1.

[0053] In this embodiment, the U-turn lifting drive 1 is arranged on the frame, and the U-turn lifting drive 1 is connected to the U-turn rotating drive 2, and the lower reversing plate 4 is driven to rotate by the U-turn rotating drive 2. During operation, the cardboard page is lifted by the lower reversing plate 4, and the lower reversing plate 4 and the upper reversing plate 3 clamp the cardboard page, and then the lower reversing plate 4 is rotated to complete the reversal of the cardboard page. In this embodiment, the cardboard page rotates at an angle of 90 degrees, and the spine of the cardboard page faces forward after the rotation.

[0054] The rotary U-turn device also includes a U-turn lifting sensor 6, which is arranged on the frame and is used to identify the lifting distance of the U-turn lifting driver 1. After the U-turn lifting sensor 6 is configured, it can timely identify whether the U-turn lifting driver 1 has driven the lower reversing plate 4 to rise to the position. It can be understood that the U-turn lifting sensor 6 is connected to the U-turn lifting driver 1 and the U-turn rotation driver 2 through the controller. After the U-turn lifting sensor 6 obtains that the output end of the U-turn lifting driver 1 has driven the U-turn rotation driver 2 to rise to the position, the U-turn lifting sensor 6 feedbacks the signal value of the U-turn lifting driver 1 to stop the action, and starts the U-turn rotation driver 2 to start rotating the lower reversing plate 4, completing the cardboard page turning process.

[0055] Furthermore, in order to adapt to cardboard pages of different thicknesses, the rotating U-turn device also includes an upper frame plate 71, an upper frame height adjustment nut 72, and an upper frame connecting shaft 73. The upper frame plate 71 is provided with a through upper frame lifting hole, and the upper frame connecting shaft 73 slides along the upper frame lifting hole. The upper frame height adjustment nut 72 is placed on the upper frame plate 71, and the upper frame connecting shaft 73 is threadedly connected to the upper frame height adjustment nut 72. The upper frame height adjustment nut 72 is threadedly connected to the upper frame connecting shaft 73, and the upper frame height adjustment nut 72 plays a role in determining the height of the upper reversing plate 3 and adjusting the height of the upper reversing plate 3. The upper frame height adjustment nut 72 is placed on the upper frame plate 71 but is not fixedly connected to the upper frame plate 71. When the upper reversing plate 3 rotates, the upper frame connecting shaft 73 can rotate together with the upper frame height adjustment nut 72 to change the height of the upper reversing plate 3.

[0056] In order to reduce the torque transmitted from the upper reversing plate 3 to the upper plate connecting shaft 73, the upper reversing plate 3 is rotatably connected to the upper plate connecting shaft 73. In this embodiment, the upper reversing plate 3 and the upper plate connecting shaft 73 are rotatably connected via a bearing. The rotation of the upper reversing plate 3 can reduce the torque transmitted to the upper plate connecting shaft 73, and reduce the situation where the upper plate connecting shaft 73 and the upper plate height adjustment nut 72 rotate relative to each other, causing the upper reversing plate 3 to change in height.

[0057] Further, in order to reduce the resistance when the upper plate height adjustment nut 72 rotates, a pressure bearing 91 is provided between the upper plate height adjustment nut 72 and the upper frame plate 71. The bearing design of the upper plate height adjustment nut 72 effectively reduces the resistance between the upper plate height adjustment nut 72 and the upper frame plate 71.

[0058] In order to conveniently adjust the height of the upper reversing plate 3, the rotary U-turn device further includes a first height adjustment hand wheel 74 and a second height adjustment hand wheel 75, wherein the first height adjustment hand wheel 74 is transmission-connected to the upper plate connecting shaft 73, and the second height adjustment hand wheel 75 is transmission-connected to the upper plate height adjustment nut 72. When the height of the upper reversing plate 3 needs to be adjusted, the U-turn height adjustment nut is locked by the second height adjustment hand wheel 75, and the spring rotates the upper plate connecting shaft 73 through the first height adjustment hand wheel 74, so that the height position of the upper reversing plate 3 can be changed. This structure can conveniently realize the height adjustment of the upper reversing plate 3.

[0059] In order to improve the conveying power of the paperboard sheets, the number of the driving rollers 51 is more than two, the number of the driving wheels 52 is the same as the driving rollers 51, and the driving wheels 52 are connected through a transmission mechanism.

[0060] In order to reliably drive the driving roller 51, the transmission mechanism is a gear mechanism, the gear mechanism includes a bridge gear 8, the driving wheels 52 are gears, and each driving wheel 52 is connected by the bridge gear 8. In this embodiment, the power of the driving wheel 52 is provided by the conveying motor of the conveying line.

[0061] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of the present invention.
