Under normal circumstances, the paper will be in a tilted state, but will not be perpendicular to the normal state.

[0033] The movable mechanism 8 is arranged on the deflection correcting mechanism 4 , and the deflection correcting mechanism 4 is used to prevent the paper 1 5 , the paper 2 6 and the paper 3 7 from being stuck on the deflection correcting mechanism 4 .

[0034] A through slot 9 is formed through the top of the transverse plate 3 , and a fixing plate 10 is fixedly connected to the top of the transverse plate 3 . Two fixing plates 10 are provided.

[0035] The correcting mechanism 4 includes a first connecting plate 42 connected to the bottom of the horizontal plate 3 through an adjusting component 41, and two first connecting plates 42 are provided. The bottom of the first connecting plate 42 is rotatably connected to a first roller 43, and the top of the first connecting plate 42 is rotatably connected to a rotating shaft 44, and a second connecting plate 45 is fixedly connected to the rotating shaft 44, and the bottom of the second connecting plate 45 is fixedly connected to a second roller 46.

[0036] The adjustment assembly 41 includes a straight rod 411 fixedly connected to the top of the first connecting plate 42, one end of the straight rod 411 passes through the through slot 9, and the straight rod 411 is slidably connected to the through slot 9, a bidirectional screw rod 412 is threadedly connected to the straight rod 411, and the bidirectional screw rod 412 is rotatably connected to the fixed plate 10, a handle 413 is fixedly connected to the bidirectional screw rod 412, and a support block 414 is fixedly connected to the straight rod 411, and the support block 414 is slidably connected to the cross plate 3. The position of the first connecting plate 42 is adjusted according to the size of the paper. When adjusting, the bidirectional screw rod 412 is driven to rotate by rotating the handle 413, and then the two straight rods 411 are driven to move relative to each other in the through slot 9, thereby driving the first connecting plate 42 to move, and adjusting the position of the first connecting plate 42.

[0037] The gear 13 is fixedly connected to the rotating shaft 44 , and the second roller 46 and the first roller 43 are both attached to the conveyor belt base surface 1 .

[0038] The movable mechanism 8 includes a mounting plate 81 fixedly connected to the transverse plate 3, the top of the mounting plate 81 is rotatably connected to a rotating plate 82, the bottom of the mounting plate 81 is fixedly connected to a cylinder 83, the cylinder 83 is electrically connected to an external power supply and is controlled by an external control program, there is only one cylinder 83, the cylinder 83 is fixedly connected to one of the racks 85, the rotating plate 82 is connected to a rack 85 via a telescopic assembly 84, the rack 85 is fixedly connected to the cylinder 83, the rack 85 is arranged above the second connecting plate 45 via a limiting assembly 86, the rack 85 is meshed with the gear 13, and two telescopic assemblies 84 are arranged. The conveyor belt base 1 is used to convey the paper.

When the two second connecting plates 45 approach each other, the second rollers 46 on the two second connecting plates 45 respectively apply thrust to the two sides of the paper, so as to straighten the paper and realize deviation correction. After that, the cylinder 83 will drive the second connecting plate 45 to recover. Each time the second connecting plate 45 implements the above steps, there is just one paper located between the two second connecting plates 45.

[0039] Embodiment 2

[0040] Based on Example 1, see Figure 2-Figure 7 shown.

[0041] The telescopic assembly 84 includes a connecting seat 841 rotatably connected to the rotating plate 82, a connecting rod 842 is fixedly connected to the connecting seat 841, a placement groove 843 is provided at one end of the connecting rod 842, a threaded sleeve 844 is threadedly connected to the connecting rod 842, a threaded rod 845 is placed in the placement groove 843, a threaded sleeve 846 is threadedly connected to the threaded rod 845, the threaded sleeve 844 and the threaded sleeve 846 are slidably connected, one end of the threaded rod 845 is fixedly connected to a connecting seat 847, and the connecting seat 847 is rotatably connected to the rack 85. When adjusting the position of the first connecting plate 42, the threaded sleeve 844 is rotated so that the threaded sleeve 844 slides on the main body 8461, so that the threaded sleeve 844 is separated from the connecting rod 842. During the adjustment process, the threaded rod 845 will be pulled out of the placement groove 843 or inserted into the placement groove 843. After the position adjustment of the first connecting plate 42 is completed, the main body 8461 is first rotated so that the limiting ring 8462 fits the end of the connecting rod 842 (and when the main body 8461 moves, under the action of the limiting ring 8463, the threaded sleeve 844 will also move), and then the threaded sleeve 844 is rotated so that the threaded sleeve 844 is fixed together with the connecting rod 842. Therefore, by setting the telescopic component 84, when correcting the deviation of paper of different sizes, the overall length of the connecting rod 842 and the threaded rod 845 can be changed according to the position change of the correction mechanism 4, so that the movable mechanism 8 can correct the deviation of paper of different sizes, and the applicability is wide.

[0042] The second threaded sleeve 846 includes a main body 8461 , a limiting ring 1 8462 is integrally formed on one side of the main body 8461 , and a limiting ring 2 8463 is integrally formed on the outer surface of the main body 8461 .

[0043] The limiting assembly 86 includes a vertical plate 861 fixedly connected to the top of the second connecting plate 45, and a movable groove 862 penetrating through the top of the rack 85. The outer surface of the vertical plate 861 is integrally formed with a support plate 863. The top of the vertical plate 861 is fixedly connected to a limiting plate 864. The limiting plate 864 and the support plate 863 are both fitted between the rack 85, and the outer surface of the vertical plate 861 is fitted between the inside of the movable groove 862.

[0044] Embodiment 3

[0045] Based on Example 1, see Figure 2 and Figure 7 shown.

[0046] The rack 85 is threadedly connected with a bolt 11, and one side of the vertical plate 861 is provided with a thread groove 12 adapted to the bolt 11. When adjusting the position of the first connecting plate 42, the bolt 11 needs to be tightened into the thread groove 12, and the position of the first connecting plate 42 is adjusted by the adjustment component 41. During the adjustment process, under the action of the bolt 11, the rack 85 and the vertical plate 861 move synchronously, and then the rack 85 and the first connecting plate 42 move synchronously, so that the rack 85 is always in a meshing state with the gear 13. Therefore, through the coordinated use of the bolt 11 and the thread groove 12, during the position change of the deviation correction mechanism 4, it is ensured that the movable mechanism 8 and the deviation correction mechanism 4 can maintain synchronous adjustment, which is convenient to use.

[0047] Embodiment 4

[0048] In combination with Embodiment 1, Embodiment 2 and Embodiment 3, see Figure 1-Figure 7 shown.

[0049] In the process of conveying each paper one by one, under the action of the cylinder 83 and the rotating plate 82, the two racks 85 are made to move relative to each other, and the transmission action of the racks 85 and the gear 13 is used to make the two second connecting plates 45 move relative to each other. When the two second connecting plates 45 are close to each other, the second rollers 46 on the two second connecting plates 45 respectively apply thrust to the two sides of the paper, so as to straighten the paper and correct the deviation, so as to avoid the paper being stuck between the two correction rails, which is beneficial to the normal conveyance of the paper and convenient to use.

[0050] The working principle of the present invention is as follows: by placing the bracket 2 on the front and rear sides of the conveyor belt base 1, the position of the first connecting plate 42 is adjusted according to the size of the paper. During adjustment, the bidirectional screw rod 412 is driven to rotate by rotating the handle 413, thereby driving the two straight rods 411 to move relative to each other in the through groove 9, thereby driving the first connecting plate 42 to move, thereby adjusting the position of the first connecting plate 42.

[0051] Afterwards, the paper is placed on the conveyor belt base surface 1 and the conveyor belt base surface 1 is used to convey the paper. When the paper moves between the two second connecting plates 45, at this time, the cylinder 83 drives one of the racks 85 to move, and then drives the rotating plate 82 to rotate through one of the telescopic components 84, and the rotating plate 82 drives the other rack 85 to move through the other telescopic component 84, so as to realize the relative movement between the two racks 85, and then drives the rotating shaft 44 to rotate through the transmission action between the rack 85 and the gear 13, and then drives the second connecting plate 45 to rotate. When the two second connecting plates 45 approach each other, the second rollers 46 on the two second connecting plates 45 respectively apply thrust to the two sides of the paper, so as to straighten the paper and realize deviation correction. Afterwards, the cylinder 83 will drive the second connecting plate 45 to recover. Each time the second connecting plate 45 implements the above steps, there is just one paper located between the two second connecting plates 45.

[0052] When adjusting the position of the first connecting plate 42, the bolt 11 needs to be tightened into the thread groove 12, and then the threaded sleeve 844 is rotated so that the threaded sleeve 844 slides on the main body 8461, so that the threaded sleeve 844 is separated from the connecting rod 842, and then the position of the first connecting plate 42 is adjusted by the adjustment component 41. During the adjustment process, under the action of the bolt 11, the rack 85 and the vertical plate 861 move synchronously, and then the rack 85 and the first connecting plate 42 move synchronously, so that The rack 85 is always in meshing state with the gear 13; during the adjustment process, the threaded rod 845 will be pulled out of or inserted into the placement groove 843. After the position adjustment of the first connecting plate 42 is completed, the main body 8461 is first rotated so that the limiting ring 1 8462 fits the end of the connecting rod 842 (and when the main body 8461 moves, under the action of the limiting ring 2 8463, the threaded sleeve 1 844 will also move), and then the threaded sleeve 1 844 is rotated so that the threaded sleeve 1 844 and the connecting rod 842 are fixed together. Therefore, through the coordinated use of the bolt 11 and the threaded groove 12, during the position change of the deviation correction mechanism 4, it is ensured that the movable mechanism 8 and the deviation correction mechanism 4 can maintain synchronous adjustment, which is convenient to use. By setting the telescopic component 84, when correcting the deviation of papers of different sizes, the overall length of the connecting rod 842 and the threaded rod 845 can be changed according to the position change of the deviation correction mechanism 4, so that the movable mechanism 8 can correct the deviation of papers of different sizes, and the applicability is wide.

[0053] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
