The correction mechanism includes a fixed sleeve that is movably disposed in the inner cavity of the mounting groove. A correction plate is connected to one side of the fixed sleeve. A connecting shaft is installed in the inner cavity of the fixed sleeve. The connecting shaft is rotatably connected to a limiting plate. A transmission component is installed at the upper end of the connecting shaft. The transmission component passes through the long groove and meshes with the drive component for transmission.

[0007] As a further embodiment of this utility model: each of the lower ends of the limiting plates is provided with an L-shaped groove, each of the inner cavities of the L-shaped grooves is equipped with a support column, each of the support columns is rotatably connected to a rubber roller column, each of the limiting plates is symmetrically connected with a limiting column on one side, and each of the outer cover is provided with a limiting hole that is movably inserted into the limiting column on both sides. As a further embodiment of this utility model: the driving assembly includes a cylinder mounted on the upper end of the outer cover, the cylinder being located in the inner cavity of the top cover, the output end of the cylinder being connected to a push rod, one side of the push rod being rotatably connected to a movable rod via two first connecting members, the end of the movable rod away from the first connecting members being rotatably connected to a second connecting member, the two second connecting members being respectively connected to a toothed plate, the toothed plate engaging with the transmission assembly for transmission.

[0008] As a further embodiment of this utility model: the lower end of each toothed plate is provided with a slide bar, the upper end of the outer cover is provided with a slide groove that slides with it, the lower end of the push rod is equipped with a positioning block, and the upper end of the outer cover is provided with a positioning groove that slides with it.

[0009] As a further embodiment of this utility model: the transmission assembly includes a drive shaft mounted on the upper end of the connecting shaft, a sleeve shaft movably sleeved on the upper end of the drive shaft, a limit strip integrally connected to the inner wall of the sleeve shaft symmetrically, a limit groove symmetrically provided on the outer side of the drive shaft for sliding contact with it, and a gear meshing with a gear plate installed on the outer side of the sleeve shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. During the conveying process of the stand-up sign paper, the drive component drives two transmission components to reciprocate. The transmission components drive the connecting shaft and the correction plate to move in opposite or opposite directions. Therefore, the correction plate continuously reciprocates. When the stand-up sign paper is conveyed, an angular deviation occurs. During the reciprocating rotation, the correction plate comes into contact with the tilted stand-up sign paper. Therefore, when it rotates, it pushes the stand-up sign paper to straighten the angle. That is, it continuously corrects the stand-up sign paper that has an angular deviation, effectively ensuring that the stand-up sign paper can be conveyed without angular deviation, avoiding misalignment in subsequent printing, thereby improving printing efficiency. 2. Based on the width of the paper, by rotating two screws, the screws move in a spiral motion within the threaded hole. This causes the bearing seats and limiting plates to move in opposite directions, thus adjusting the distance between the two limiting plates. The two sides of the stand-up label are in contact with multiple rubber rollers. Due to the rotating design of the rubber rollers, when the stand-up label rubs against the rubber rollers during transport, the rubber rollers can rotate, effectively reducing the frictional resistance on the stand-up label, improving the stability of the transport, facilitating the limiting transport of the stand-up label, and preventing tilting during transport, which could lead to errors in subsequent printing positions and affect printing efficiency.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-8 A paper feeding device for stand-up sign includes an outer cover 1. A conveyor 3 is installed in the lower part of the inner cavity of the outer cover 1. Limiting mechanisms 2 are provided on both sides of the inner cavity of the outer cover 1. The limiting mechanism 2 includes a limiting plate 21. A bearing seat 22 is installed on one side of the limiting plate 21. A screw 23 is rotatably connected to the bearing seat 22. A threaded hole 9 is provided on the outer side of the outer cover 1, which is threadedly connected to the screw 23. An L-shaped groove 25 is provided at the lower end of the limiting plate 21. A support column is installed at the top of the inner cavity of the L-shaped groove 25. A rubber roller column 26 is rotatably connected to the outer side of the support column. A limiting column 24 is symmetrically connected on one side of the limiting plate 21. Limiting holes 10 are provided on both sides of the outer cover 1, which are movably inserted into the limiting column 24. During the conveying process of the stand-up sign paper on conveyor 3, the distance between the two limiting plates 21 is adjusted according to the width of the paper. This is achieved by rotating two screws 23, which move spirally within the threaded hole 9. The two screws 23 then drive the bearing seat 22 and the limiting plates 21 to move in opposite directions, thus adjusting the distance between the two limiting plates 21. Meanwhile, the limiting post 24 on the outer side of the limiting plate 21 moves within the limiting hole 10, effectively improving the stability of the limiting plate 21's displacement. Furthermore, when the stand-up sign paper passes the position of the limiting plate 21, both sides of the paper come into contact with multiple rubber rollers 26. Due to the rotating design of the rubber rollers 26, they can rotate during the friction between the paper and the rollers, effectively reducing the frictional resistance and improving the stability of the stand-up sign's conveying.

[0016] A top cover 4 is installed on the upper end of the outer cover 1, and a drive assembly 6 is installed on the upper end of the outer cover 1. A long groove 7 is provided on the upper end of the outer cover 1. The drive assembly 6 includes a cylinder 61 installed on the upper end of the outer cover 1. The cylinder 61 is located in the inner cavity of the top cover 4. The output end of the cylinder 61 is connected to a push rod 62. One side of the push rod 62 is rotatably connected to a movable rod 65 through two first connecting parts 64. The end of the movable rod 65 away from the first connecting parts 64 is rotatably connected to a second connecting part 66. The two second connecting parts 66 are respectively connected to a toothed plate 67. The toothed plate 67 meshes with the transmission assembly for transmission.

[0017] The lower end of the toothed plate 67 is provided with a slide bar 68, the upper end of the outer cover 1 is provided with a slide groove 11 that slides with it, the lower end of the push rod 62 is provided with a positioning block 63, and the upper end of the outer cover 1 is provided with a positioning groove 12 that slides with it.

[0018] The output end of cylinder 61 drives push rod 62 to move to the right. Push rod 62 drives the two first connecting parts 64 and movable rod 65 to move. The positioning block 63 at the lower end of push rod 62 moves within the cavity of positioning groove 12, effectively improving the stability of push rod 62's movement. Since the sliding strips 68 at the lower end of the two toothed plates are designed to be movable within the cavity of sliding groove 11, the other ends of the two movable rods 65 drive the second connecting part 66 and toothed plate 67 to move back and forth, respectively. As a result, the two toothed plates 67 drive the transmission assembly to move in opposite directions, and the transmission assembly drives the connecting shaft and correction plate 89 to move in opposite directions. Then, the output end of cylinder 61 resets and moves, reversing the operation. Similarly, the transmission component drives the connecting shaft and the correction plate 89 to move in opposite directions, thus resetting the correction plate 89. Therefore, the correction plate 89 continuously reciprocates. When the stand-up paper is being fed, the stand-up paper experiences angular displacement. During the reciprocating rotation, the correction plate 89 comes into contact with the tilted stand-up paper. Since one of the endpoints of the correction plate 89 is flush with the limit plate 21 during the reciprocating rotation, it pushes the stand-up paper to straighten its angle during rotation. This continuously corrects the angle displacement of the stand-up paper, effectively ensuring that the stand-up paper can be fed without angular displacement, avoiding misalignment during subsequent printing, and thus improving printing efficiency.

[0019] A mounting groove 27 is provided on one side of the limiting plate 21. A correction mechanism 8 is provided in the inner cavity of the mounting groove 27. The correction mechanism 8 includes a fixed sleeve 88 that is movably disposed in the inner cavity of the mounting groove 27. A correction plate 89 is connected to one side of the fixed sleeve 88. A connecting shaft is installed in the inner cavity of the fixed sleeve 88. The connecting shaft is rotatably connected to the limiting plate 21. A transmission component is installed at the upper end of the connecting shaft. The transmission component passes through the long groove 7 and meshes with the drive component 6 for transmission.

[0020] The transmission assembly includes a drive shaft 81 mounted on the upper end of the connecting shaft, a sleeve shaft 82 movably sleeved on the upper end of the drive shaft 81, a limit strip 811 symmetrically and integrally connected to the inner wall of the sleeve shaft 82, a limit groove 810 symmetrically provided on the outer side of the drive shaft 81 for sliding contact with it, and a gear 83 that meshes with the gear plate 67 is mounted on the outer side of the sleeve shaft 82.

[0021] When the two toothed plates 67 drive the gear 83 to rotate, the gear 83 drives the sleeve shaft 82 to rotate, and the limiting strip 811 in the inner cavity of the sleeve shaft 82 drives the drive shaft 81 with the limiting groove 810 to rotate. The drive shaft 81 drives the connecting shaft and the fixed sleeve 88 to rotate, and the fixed sleeve 88 drives the correction plate 89 to reciprocate to perform angle correction operation on the stand-up paper.

[0022] The top of the sleeve shaft 82 is provided with a support groove 84, the inner cavity of the support groove 84 is equipped with a bearing 85, and a fixing column 86 is rotatably installed in the middle of the bearing 85. The upper end of the top cover 4 is symmetrically provided with a fine groove 5, and the fixing column 86 passes through the fine groove 5 and extends above it.

[0023] When the spacing of the limiting plate 21 is adjusted, the limiting plate 21 drives the connecting shaft to move synchronously. The limiting plate 21 also drives the transmission component, the fixed sleeve 88, and the correction plate 89 to move synchronously. Consequently, the position of the gear 83 in the transmission component also moves synchronously. Therefore, by pulling the fixed column 86 upward, the fixed column 86 drives the sleeve shaft 82 to move upward. The limiting strip 811 in the inner cavity of the sleeve shaft 82 is fixed and stable in the limiting groove 810 on the outside of the drive shaft 81. After the position of the limiting plate 21 is adjusted and fixed, the fixed column 86 is lowered, and the fixed column 86 and the sleeve shaft 82 naturally move downward by gravity. The gear 83 also moves downward synchronously and re-meets with the gear plate 67, thus avoiding positional conflict between the limiting plate 21 and the drive component 6 when the correction mechanism is moved.

[0024] Working Principle: In use, this invention, based on the width of the paper, rotates two screws 23. The screws 23 move spirally within the threaded hole 9, causing the bearing seat 22 and the limiting plate 21 to move in opposite directions, thus adjusting the distance between the two limiting plates 21. The two sides of the stand-up sign paper are in contact with multiple rubber rollers 26. Due to the rotating design of the rubber rollers 26, they can rotate when the stand-up sign paper is in contact with and rubbed against them, effectively reducing the frictional resistance and improving the stability of the stand-up sign's conveying. During the conveying process of the stand-up sign paper on the conveyor 3, the output end of the cylinder 61 drives the push rod 62 to move back and forth. The push rod 62 then moves the two first connecting parts 64 and the movable rod 65. The other ends of the two movable rods 65 respectively... The second connecting piece 66 and the toothed plate 67 are moved back and forth, so that the two toothed plates 67 drive the gear 83 to move synchronously in opposite directions or synchronously in the same direction. The gear drives the transmission component, the connecting shaft and the correction plate 89 to move in opposite or opposite directions. Therefore, the correction plate 89 continuously reciprocates. When the stand-up paper is being fed, the stand-up paper may experience angular deviation. During the reciprocating rotation, the correction plate 89 comes into contact with the tilted stand-up paper. Since one of the endpoints of the correction plate 89 is flush with the limit plate 21 during the reciprocating rotation, it pushes the stand-up paper to straighten the angle during rotation. That is, it continuously corrects the stand-up paper that has experienced angular deviation, effectively ensuring that the stand-up paper can be fed without angular deviation, avoiding misalignment in subsequent printing, and thus improving printing efficiency.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
