Description

Technical Field

[0001] The utility model relates to the technical field of flipping and conveying equipment, and specifically relates to a cardboard flipping and conveying mechanism. Background Art

[0002] Cardboard is usually made from various plant fibers, and some non-plant fibers are also added. It is manufactured on a cardboard machine. Some special cardboard also incorporates animal fibers such as wool or mineral fibers such as asbestos. In the production and processing of cardboard, in order to improve the quality or aesthetics of the cardboard, it is usually necessary to process both sides of the cardboard. In actual work, a turning device is required to turn the cardboard over.

[0003] In order to facilitate the flipping and conveying of cardboard, many improvements have been made to the cardboard flipping and conveying mechanism in the prior art. For example, the patent with the publication number CN211003705U discloses a cardboard flipping and conveying mechanism, which includes a frame, a front conveying mechanism, a first flipping mechanism, a second flipping mechanism, and a rear conveying mechanism arranged in sequence from front to back. The first flipping mechanism includes a plurality of first guiding roller groups arranged in sequence from front to back. Each first guiding roller group includes two first guiding rollers, and the first guiding rollers gradually incline downward from left to right. Among adjacent two first guiding roller groups, the angle between the rear first guiding roller and the horizontal plane is greater than the angle between the front first guiding roller and the horizontal plane. The second flipping mechanism includes a plurality of second guiding roller groups arranged in sequence from front to back. Each second guiding roller group includes two second guiding rollers, and the second guiding rollers gradually incline upward from left to right. Among adjacent two second guiding roller groups, the angle between the rear second guiding roller and the horizontal plane is less than the angle between the front second guiding roller and the horizontal plane. This utility model can flip the front and back sides of the cardboard while conveying the cardboard, and can realize the continuous conveying of the cardboard, thus improving the work efficiency.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0029] Embodiment 1

[0030] Please refer to Figures 1-7, A cardboard flipping and conveying mechanism, including two conveying devices 1 for conveying cardboard. There is a bearing frame 2 between the two conveying devices 1. Circular holes 3 are formed through both opposite sides of the bearing frame 2 and are in the same direction as the conveying direction of the conveying device 1. A rotating disk 4 is rotatably connected in the circular hole 3. A first installation groove 5 is formed through one side of the rotating disk 4. In the first installation groove 5, there are two groups of fixing plates 6, with two in each group. A driving roller 7 is rotatably connected between each two fixing plates 6 in each group. An annular conveyor belt 8 for conveying cardboard is sleeved between the sides of the two driving rollers 7. A first driving unit 9 for driving the rotating disk 4 to rotate is provided in the bearing frame 2. A second driving unit 10 for driving the annular conveyor belt 8 to drive is provided on the side of the fixing plate 6. The first driving unit 9 includes an annular gear 11 fixedly installed on the side of the rotating disk 4. A rotating groove 12 adapted to the annular gear 11 is formed on the inner side wall of the circular hole 3. A first driving motor 13 is fixedly connected in the bearing frame 2. A first gear 14 meshing with the annular gear 11 is fixedly installed at the output end of the first driving motor 13.

[0031] Specific implementation in this embodiment: The above-mentioned conveying device 1 is a known prior art for conveying cardboard. The cardboard is conveyed through the conveying device 1, and there is a certain distance between adjacent cardboard on the conveying device 1. The second driving unit 10 drives the two annular conveyor belts 8 to drive. The distance between the two annular conveyor belts 8 is adapted to the thickness of the cardboard. When the cardboard is conveyed between the two annular conveyor belts 8, the two annular conveyor belts 8 can press the cardboard. When the cardboard leaves the first conveying device 1, it moves between the two annular conveyor belts 8. When the cardboard is completely conveyed between the two annular conveyor belts 8, the first driving motor 13 is started. The output end of the first driving motor 13 drives the first gear 14 to rotate. When the first gear 14 rotates, it drives the annular gear 11 to rotate in the rotating groove 12. The annular gear 11 drives the rotating disk 4 to rotate. When the rotating disk 4 rotates, it drives the fixing plate 6 and the annular conveyor belt 8 to rotate, thereby flipping the cardboard. After the cardboard is flipped, the subsequent cardboard just reaches one end of the annular conveyor belt 8. At this time, the driving annular conveyor belt 8 transports the flipped cardboard to the next conveying device 1 and transports the subsequent cardboard to between the two annular conveyor belts 8 again. The two annular conveyor belts 8 press the cardboard, and the first driving unit 9 can rotate the rotating disk 4, enabling the flipping and conveying of cardboard of different sizes or hardnesses, and improving the application range of the overall device.

A second gear 26 that meshes with each other is fixedly installed on the side of one end of the upper driving roller 7 and the side of the rotating shaft 23 respectively.

[0034] Specific implementation manner in this embodiment: After starting the second driving motor 19, the output end of the second driving motor 19 drives one of the first transmission wheels 20 to rotate. This first transmission wheel 20 drives the other first transmission wheel 20 to rotate through the first transmission belt 21. The first transmission wheel 20 drives the bidirectional lead screw 18 to rotate. The threads on the side of the bidirectional lead screw 18 are reverse and symmetric. When the bidirectional lead screw 18 rotates, it drives the two sliding blocks 15 in the same sliding groove 16 to move towards or away from each other, thereby adjusting the distance between the two annular conveyor belts 8, which is suitable for the flipping and conveying of cardboard with different thicknesses, and further improving the applicable range of the flipping and conveying of cardboard. Start the third driving motor 22. The output end of the third driving motor 22 drives one of the second transmission wheels 24 to rotate. When this second transmission wheel 24 rotates, it drives the other second transmission wheel 24 to rotate through the second transmission belt 25. The two second transmission wheels 24 respectively drive the lower driving roller 7 and the rotating shaft 23 to rotate. When the rotating shaft 23 rotates, it drives one of the second gears 26 to rotate. This second gear 26 drives the other second gear 26 to rotate. This second gear 26 drives the upper driving roller 7 to rotate. Several driving rollers 7 drive the annular conveyor belts 8 to drive simultaneously and synchronously. Both of the two annular conveyor belts 8 can convey the cardboard, improving the efficiency of conveying the cardboard. It should be noted that the above upper and lower are differentiating words and do not represent their specific positions.

[0037] The specific implementation in this embodiment: When adjusting the distance between the two annular conveyor belts 8, the tension of the second transmission belt 25 will change. At this time, by rotating the adjusting bolt 28, the adjusting bolt 28 drives the tension pulley 30 to move, and adjusts the tension of the second transmission belt 25 by the tension pulley 30, so that the second transmission belt 25 can stably drive the two second transmission wheels 24 to rotate simultaneously and synchronously. After the adjustment is completed, tighten the limit nut 31 to limit and fix the position of the adjusting bolt 28, so that the two annular conveyor belts 8 can still convey and flip the cardboard simultaneously and synchronously after adjustment.
