This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.
[0029] Example 1
[0030] like Figure 1As shown, this embodiment is a paper straightening device before tiling of a paper feeder, including a frame 9, to which a side patting mechanism, a belt conveyor mechanism for conveying a paper stack 6 and a front baffle 12 are connected, the side patting mechanism is located above both sides of the belt conveyor mechanism, and the front baffle 12 is located at the rear end of the belt conveyor mechanism, the side patting mechanism includes a first transmission surface side pat 4, a first side pat driving cylinder, a second operating surface side pat 5 and a second side pat driving cylinder, the first transmission surface side pat 4 is fixedly connected to the first side pat driving cylinder and driven thereby, the second operating surface side pat 5 is fixedly connected to the second side pat driving cylinder and driven thereby, the first transmission surface side pat 4 and the second operating surface side pat 5 are respectively located above both sides of the belt conveyor, and the first side pat driving cylinder and the second side pat driving cylinder are both fixedly connected to the frame 9.
[0031] like Figure 2 As shown, the belt conveying mechanism includes a paper conveying belt 2, four conveying belt fixed pulley groups and a conveying belt driving group. The four conveying belt fixed pulley groups are each composed of two fixed pulleys. The conveying belt driving group is composed of a fixed pulley and a conveying belt driving motor 1. Each fixed pulley and the conveying belt driving motor 1 are fixedly connected to the frame 9. The paper conveying belt 2 is driven by the four conveying belt fixed pulley groups and the conveying belt driving group. The four conveying belt fixed pulley groups and the conveying belt driving group are located on the same straight line. Except for the first and last two groups, a belt positioning mechanism group is set between each two of them. The paper conveying belt 2 is positioned by the four belt positioning mechanism groups to form four grooves.
[0032] Specifically, a belt positioning mechanism group includes two belt positioning mechanisms, which are respectively located on the left and right sides of the paper feeding belt 2. A belt positioning mechanism includes a fixed pulley and a pulley rod, one end of the pulley rod is connected to the fixed pulley, and the other end is fixedly connected to the frame 9.
[0033] like Figure 2 and Figure 3 As shown, each groove formed by the paper feeding belt 2 positioned by the belt positioning mechanism group is provided with a paper supporting rod 3, and the frame 9 is also fixedly connected to a paper supporting rod supporting mechanism 7, the left sides of all the paper supporting rods 3 are connected to the first paper supporting rod supporting mechanism, and the right sides of all the paper supporting rods 3 are connected to the second paper supporting rod supporting mechanism.
[0034] like Figure 4As shown, the paper support rod support mechanism 7 includes a first paper support rod support frame 701 and a second paper support rod support frame 702, the first paper support rod support frame 701 and the second paper support rod support frame 702 are respectively located below the two sides of the belt conveyor mechanism, the paper support rod support frame 701 is fixedly connected to two paper support rod driving cylinders 8 and driven thereby, the second paper support rod support frame 702 is fixedly connected to two paper support rod driving cylinders 8 and driven thereby, and the four paper support rod driving cylinders 8 are all fixedly connected to the frame 9. The left sides of all paper support rods 3 are connected to the first paper support rod support frame 701, and the right sides of all paper support rods 3 are connected to the second paper support rod support frame 702.
[0035] The cross section of the paper supporting rod 3 includes a circular portion, which is located at the upper end of the cross section of the paper supporting rod 3. The paper supporting rod 3 contacts the paper stack 6 through the circular portion, and the contact area is smaller. When the side patting mechanism performs paper sorting on the paper stack, the friction resistance of the paper stack is smaller, thereby improving the paper sorting effect of the present invention.
[0036] The upper part of the middle position of the paper supporting rod 3 is provided with a groove.
[0037] A protrusion is provided at the lower part of the middle position of the paper supporting rod 3 to reinforce the paper supporting rod 3 and prevent it from breaking.
[0038] Both sides of the paper support rod 3 are provided with an L-shaped part for connecting to the paper support rod support mechanism 7. The short side of the L-shaped part can be fixedly connected to the first paper support rod support frame 701 or the second paper support rod support frame 702 by multiple screws, making the connection more stable.
[0039] like Figure 1 As shown, the frame 9 is also connected in sequence with a paper pressing wheel driving cylinder 11 and an upper paper pressing wheel 10. The upper paper pressing wheel 10 is fixedly connected to the paper pressing wheel driving cylinder 11 and driven thereby. The upper paper pressing wheel 10 is located above the belt conveyor mechanism.
[0040] Specific runtime:
[0041] The conveyor belt drive motor 1 drives the paper stack 6 to be input, and the paper head is conveyed to the front baffle 12 position. After the paper stack 6 stops at the position, Figure 1 In the state shown, the paper supporting rod driving cylinder 8 drives the paper supporting rod 3 to rise, lifting the paper stack 6 as shown in FIG. Figure 2 In the state shown, after the paper stack is lifted, the first transmission surface side slap 4 and the second operating surface side slap 5 act simultaneously to align the two sides of the paper stack 6 and complete the paper sorting action. Subsequently, the paper support rod driving cylinder 8 drives the paper support rod 3 to descend, so that the paper stack 6 returns to the conveyor belt 2. At the same time, the paper pressure wheel driving cylinder 11 drives the upper paper pressure wheel 10 to descend, ensuring that the bent paper can also pass through the front baffle 12 smoothly for stable paper feeding; after the paper stack 6 is completely output from the front baffle 12 after laying, the upper paper pressure wheel returns, and the second paper stack enters again, repeating the previous cycle action.
[0042] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
