Description

Technical Field

[0001] This application relates to the field of paper correction technology, and in particular to an automatic paper correction device. Background Technology

[0002] In the printing industry, the proper placement of paper is a crucial prerequisite for ensuring the quality of paper printing and the smooth progress of subsequent paper packaging processes.

[0003] Some papers may accidentally become scattered during transport and storage. In such cases, manual correction is commonly used to organize the scattered papers and restore their neatness. However, manual correction not only requires a lot of manpower and time, but also has relatively low efficiency due to the limitations of manual operation. Utility Model Content

[0004] To facilitate automatic correction of disordered paper, improve the efficiency and quality of paper correction, and reduce labor costs, this application provides an automatic paper correction device.

[0005] The paper automatic correction device provided in this application adopts the following technical solution:

[0006] An automatic paper correction device includes a base, on which a frame is fixedly mounted. A drive roller is rotatably mounted at one end of the frame, and a driven roller is rotatably mounted at the other end. A conveyor belt drives the drive roller and the driven roller. A drive assembly is mounted on the frame to drive the drive roller to rotate. A feeding mechanism is also mounted on the base, located at one end of the frame, and is used to sequentially feed disordered papers onto the conveyor belt. A rotating shaft is rotatably mounted on each of the two side walls of the frame, with the axis of the rotating shaft perpendicular to the side wall and the two rotating shafts rotating in opposite directions. A lever is vertically and fixedly mounted at the end of each rotating shaft. An arc-shaped cover is fixedly mounted at the other end of the frame, surrounding the end of the conveyor belt. A paper drop box is located at the bottom of the arc-shaped cover, and a paper drop opening communicating with the top of the paper drop box is provided on the arc-shaped cover.

[0007] By adopting the above technical solution, the feeding mechanism sequentially feeds the disordered paper onto the conveyor belt. The drive component drives the active roller to rotate, which in turn drives the conveyor belt to move, and the paper on the conveyor belt moves with the belt. When the paper moves to the position of the rotating shafts on both sides of the frame, since the two rotating shafts rotate in opposite directions, a lever on one rotating shaft moves towards the feeding mechanism towards the paper, while a lever on the other rotating shaft moves away from the feeding mechanism towards the paper. Under the simultaneous action of the two levers, the paper is twisted and straightened, completing the paper correction action. After being straightened, the paper continues to move with the conveyor belt to the other end of the frame, and under the guidance of the arc-shaped cover, it falls into the paper drop box through the paper drop outlet, completing the automatic paper correction and collection. The entire process requires no manual intervention, improving the efficiency and quality of paper correction and saving labor costs.

[0008] Preferably, the drive assembly includes a first motor, an incomplete gear, and a meshing gear. The incomplete gear is rotatably engaged with the frame, the meshing gear is coaxially fixed with the drive pulley, and the incomplete gear can mesh with the meshing gear. The first motor is fixedly mounted on the frame, and the output end of the first motor is fixedly connected to the incomplete gear.

[0009] By adopting the above technical solution, when the first motor starts, it drives the incomplete gear to rotate. When the toothed part of the incomplete gear meshes with the meshing gear, it drives the meshing gear to rotate, which in turn drives the drive roller to rotate, causing the conveyor belt to run and realizing the paper transport. When the toothless part of the incomplete gear rotates to be opposite the meshing gear, the meshing gear stops rotating, and the conveyor belt also stops moving. At this time, the paper just enters the position of the rotating shaft for correction, giving the lever more time to perform accurate correction operations on the paper and improving the correction effect.

[0010] Preferably, the feeding mechanism includes a feeding frame, a feeding platform, a friction roller, a rotating component, and a sliding component. The feeding frame is fixedly mounted on the base. The feeding platform slides vertically on the feeding frame. The sliding component drives the feeding platform to slide. The friction roller rotates on the feeding frame and is located directly above the feeding platform. The rotating component drives the friction roller to rotate.

[0011] By adopting the above technical solution, the messy paper is piled on the feeding platform. The sliding component drives the feeding platform to move vertically, adjusting the height of the feeding platform to meet the needs of paper stacking at different heights, and ensuring that the top of the messy paper is in contact with the friction roller. At the same time, the rotating component drives the friction roller to rotate, and the friction roller pushes the paper one by one onto the conveyor belt through friction, thus realizing the automatic feeding operation of paper.

[0012] Preferably, the sliding component includes an electric push rod, which is fixedly mounted on the base, and the output end of the electric push rod is fixedly connected to the bottom of the loading platform.

[0013] By adopting the above technical solution, the electric actuator has a compact structure, occupies little space, and will not cause too much interference to the layout and operation of the entire device, further enhancing the practicality and stability of the device.

[0014] Preferably, the rotating component includes a driving sprocket, a driven sprocket, a transmission chain, a first reversing gear, and a second reversing gear. The driving sprocket is coaxially fixed on the driving roller or the driven roller, the driven sprocket rotates on the feeding frame, one end of the transmission chain is sleeved on the driving sprocket, and the other end of the transmission chain is sleeved on the driven sprocket. The driven sprocket is coaxially fixed with the first reversing gear, and the second reversing gear is coaxially fixed with the friction roller. The first reversing gear and the second reversing gear mesh with each other.

[0015] By adopting the above technical solution, the rotation of the driving or driven roller is used as a power source. Through the transmission of the driving sprocket, transmission chain, and driven sprocket, the power is transmitted to the first reversing gear. The first reversing gear meshes with the second reversing gear, thereby changing the direction of the power and causing the friction roller to rotate. At this time, the friction roller can push the paper onto the conveyor belt. Furthermore, when the conveyor belt stops, the friction roller also stops accordingly, ensuring the rhythm of paper feeding and paper correction actions.

[0016] Preferably, an anti-drift guard is fixedly installed on the frame, and a gap is left between the anti-drift guard and the top of the conveyor belt for the paper to pass through.

[0017] By adopting the above technical solution, the anti-floating barrier prevents the paper from floating up due to airflow and other factors during the transmission process. When the paper moves on the conveyor belt, the gap between the anti-floating barrier and the top of the conveyor belt allows the paper to pass through smoothly while limiting the range of paper floating, ensuring that the paper always moves stably on the conveyor belt.

[0018] Preferably, the anti-drift barrier is bent away from the conveyor belt at the end near the feeding mechanism.

[0019] By adopting the above technical solution, the anti-floating barrier is bent away from the conveyor belt at the end near the feeding mechanism, forming a shape similar to a trumpet. When the paper is fed, this bent part can play a guiding role, making it easier for the paper to enter the gap between the anti-floating barrier and the conveyor belt, thus improving the smoothness of feeding.

[0020] Preferably, a paper-blocking end piece is fixedly provided on the paper drop opening, the paper-blocking end piece is located inside the arc-shaped cover, and the paper-blocking end piece is provided on the edge of the paper drop opening near the feeding mechanism.

[0021] By adopting the above technical solution, the paper stop end piece can block the paper before it falls into the paper drop box, preventing the paper from moving too far forward due to inertia and jumping out of the paper drop opening. The paper stop end piece can effectively restrict the paper within the range of the paper drop opening, ensuring that the paper falls accurately into the paper drop box.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By setting up a feeding mechanism, conveyor belt, two rotating shafts with opposite rotation directions, lever, arc-shaped cover, and paper drop box, the paper is automatically corrected, improving the efficiency and quality of paper correction and reducing labor costs;

[0024] 2. By setting up an incomplete gear and meshing gear engagement, intermittent movement of the conveyor belt is achieved, providing sufficient time for the paper to be corrected at the rotating shaft, thus improving the correction effect;

[0025] 3. By setting up anti-floating barriers and a curved structure at the end of the anti-floating barriers near the feeding mechanism, the paper is effectively prevented from floating up during transmission, ensuring stable paper transmission. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-4This application will be described in further detail.

[0032] This application discloses an automatic paper correction device, referring to... Figure 1 The device includes a base 1, on which a frame 11 is fixedly mounted. A drive roller 12 is rotatably mounted at one end of the frame 11, and a driven roller 13 is rotatably mounted at the other end. The drive roller 12 and driven roller 13 are at the same horizontal height and have the same diameter. A conveyor belt 14 is provided between the drive roller 12 and driven roller 13 for transmission. The conveyor belt 14 can be further configured as a synchronous belt that meshes with the drive roller 12 and driven roller 13 respectively to prevent slippage during transmission. A drive assembly 2 is provided on the frame 11 to drive the drive roller 12 to rotate. A feeding mechanism 3 is also provided on the base 1, located at one end of the frame 11, and is used to sequentially feed disordered paper onto the conveyor belt 14. Under the action of the feeding assembly, disordered paper is sequentially fed onto the conveyor belt 14, which then transports the paper.

[0033] Reference Figure 1 and Figure 4 A rotating shaft 15 is rotatably mounted on each of the two side walls of the frame 11, with the axis of the rotating shaft 15 perpendicular to the side wall of the frame 11. A second motor 152 is fixedly mounted on each side of the frame 11, corresponding to the rotating shaft 15 one-to-one, and the drive shaft of the second motor 152 is fixedly connected to the rotating shaft 15. The two rotating shafts 15 rotate in opposite directions. A lever 151 is vertically and fixedly mounted on each rotating shaft 15, with the distance between the two levers 151 equal to the width of the paper. When the conveyor belt 14 transports the paper to above the rotating shaft 15, the rotating shaft 15 on one side of the frame 11 drives the lever 151 to move one side of the paper, with the lever 151 moving towards the feeding mechanism 3. The rotating shaft 15 on the other side of the frame 11 drives the lever 151 to move the other side of the paper, with the lever 151 moving away from the feeding mechanism 3. Under the simultaneous action of the two levers 151, the paper is twisted and straightened.

[0034] Reference Figure 1 and Figure 4 An arc-shaped cover 4 is fixedly installed at the other end of the frame 11. The arc-shaped cover 4 surrounds the end of the conveyor belt 14, and a paper drop box 41 is installed at the bottom of the arc-shaped cover 4. A paper drop opening 42 is opened on the arc-shaped cover 4, which communicates with the top of the paper drop box 41. A paper stop end piece 421 is fixedly installed on the paper drop opening 42. The paper stop end piece 421 is located inside the arc-shaped cover 4 and is set on the edge of the paper drop opening 42 near the feeding mechanism 3. After being straightened, the paper continues to move with the conveyor belt 14 to the end of the frame 11 away from the feeding mechanism 3. After the paper leaves the conveyor belt 14, it falls into the arc-shaped cover 4. Guided by the arc-shaped cover 4, the paper slides along the arc-shaped cover 4 and finally falls into the paper drop box 41 through the paper drop opening 42, completing the automatic correction and collection of the paper.

[0035] To allow the paper to be rotated and corrected by lever 151 while it is stationary, refer to... Figure 3 The drive assembly 2 includes a first motor 21, an incomplete gear 22, and a meshing gear 23. The incomplete gear 22 is rotatably engaged with the frame 11, and the meshing gear 23 is coaxially fixed with the drive pulley. The incomplete gear 22 can mesh with the meshing gear 23. The first motor 21 is fixedly mounted on the frame 11, and its output end is fixedly connected to the incomplete gear 22. The teeth of the incomplete gear 22 are only partially formed on its circumference. When the toothless portion of the incomplete gear 22 rotates to face the meshing gear 23, the paper is positioned above the rotating shaft 15. The lever 151 of the rotating shaft 15 then rotates until it exposes the conveyor belt 14. The meshing gear 23 stops rotating, and the conveyor belt 14 also pauses, allowing the lever 151 more time to move the stationary paper.

[0036] To achieve automatic paper feeding and ensure coordination between the feeding and correction actions, refer to Figures 1 to 4 The feeding mechanism 3 includes a feeding frame 31, a feeding platform 32, a friction roller 33, a rotating component 34, and a sliding component. The feeding frame 31 is fixedly mounted on the base 1, and the feeding platform 32 slides vertically on the feeding frame 31. The sliding component drives the feeding platform 32 to slide. Specifically, the sliding component includes an electric push rod 35, which is fixedly mounted on the base 1. The output end of the electric push rod 35 is fixedly connected to the bottom of the feeding platform 32, pushing the feeding platform 32 to slide vertically on the feeding frame 31. The friction roller 33 rotates on the feeding frame 31 and is located directly above the feeding platform 32. The friction roller 33 can contact the paper surface and push the paper onto the conveyor belt 14 one by one through friction.

[0037] Reference Figure 1 and Figure 2 The rotating component 34 drives the friction roller 33 to rotate. The rotating component 34 includes a driving sprocket 341, a driven sprocket 342, a transmission chain 343, a first reversing gear 344, and a second reversing gear 345. The driving sprocket 341 is coaxially fixed to either the driving roller 12 or the driven roller 13. In this embodiment, the driving sprocket 341 and the driven roller 13 are coaxially fixed. The driven sprocket 342 rotates on the feeding frame 31. One end of the transmission chain 343 is sleeved on the driving sprocket 341, and the other end is sleeved on the driven sprocket 342. The driven sprocket 342 is coaxially fixed to the first reversing gear 344, and the second reversing gear 345 is coaxially fixed to the friction roller 33. The first reversing gear 344 and the second reversing gear 345 mesh with each other. When the conveyor belt stops, the friction roller also stops accordingly, ensuring coordination between paper feeding and paper correction actions.

[0038] To prevent the paper from floating on conveyor belt 14, refer to Figure 1 An anti-floating barrier 16 is fixedly installed on the frame 11. A gap is left between the anti-floating barrier 16 and the top of the conveyor belt 14 for the paper to pass through. The anti-floating barrier 16 is bent away from the conveyor belt 14 at one end near the feeding mechanism 3, forming a shape similar to a trumpet. When the paper is fed, this bent part can play a guiding role, making it easier for the paper to enter the gap between the anti-floating barrier 16 and the conveyor belt 14.

[0039] The implementation principle of the automatic paper correction device in this application embodiment is as follows: Random sheets of paper are placed on the loading platform 32. An electric push rod 35 pushes the loading platform 32 upwards, causing the top layer of paper to contact the friction roller 33. Driven by the driving roller 12 and the driven roller 13, the conveyor belt 14 moves. Simultaneously, through the transmission of the driving sprocket 341, chain, and driven sprocket 342, and the reversing of the first reversing gear 344 and the second reversing gear 345, the friction roller 33 rotates, conveying the paper one by one onto the conveyor belt 14. When the paper is transported by the conveyor belt 14 to the rotating shaft 15, the toothless part of the incomplete gear 22 aligns with the meshing gear 23, and the conveyor belt 14 pauses. The rotating shaft 15 on one side of the frame 11 drives the lever 151 to move one side of the paper, with the lever 151 moving towards the loading mechanism 3. The rotating shaft 15 on the other side of the frame 11 drives the lever 151 to move the other side of the paper, with the lever 151 moving away from the loading mechanism 3. Under the simultaneous action of the two levers 151, the paper is twisted and straightened. After the paper is straightened, the incomplete gear 22 and the meshing gear 23 re-engage, and the paper finally moves to the end of the frame 11 away from the feeding mechanism 3. After leaving the conveyor belt 14, it falls into the arc-shaped cover 4. Guided by the arc-shaped cover 4, it falls into the paper box 41 through the paper drop outlet 42, completing the automatic correction and collection of the paper.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
