Description

Technical Field

[0001] This application relates to the field of certificate processing, and in particular to a certificate folding device. Background Technology

[0002] Certificates, as legal documents issued by institutions, schools, organizations, etc., to prove qualifications, academic qualifications, or rights, are important proof of the authenticity of facts. Due to their extremely wide range of applications, covering many industries such as education, professional qualifications, and honors, there is a diversity of certificate types. Although the content of different certificates varies greatly, they have a high degree of consistency in structure. They are usually composed of two parts: a cover and a paper inner core. In order to facilitate carrying and prevent damage to the inner core, the cover must be folded during the manufacturing process to facilitate the subsequent sealing of the inner core and enhance the overall stiffness.

[0003] For example, utility model patent CN209740373U discloses a certificate folding device, including a folding platform, a vertical guide rail, a folding rod, and a first folding plate and a second folding plate located on both sides of the folding rod; the vertical guide rail is fixedly installed on the folding platform; the folding rod is movably fitted to the vertical guide rail; when the folding rod moves downward to the target position, the folding rod presses down on the middle of the certificate to form a fold line; the first folding plate and the second folding plate are rotatably fitted to the folding platform to drive the certificate to be folded along the fold line; the left side of the first folding plate has a first limiting strip, which facilitates the positioning of the certificate, and the right side of the second folding plate has a second limiting strip, which also facilitates the positioning of the certificate.

[0004] With the aforementioned back-folding device, the positions of the first and second limiting strips are fixed, which means that the device is only suitable for certificates of a specific size. When the size of the certificate changes, the first and second limiting strips cannot be adjusted accordingly. The device has poor versatility and adaptability and needs to be improved. Summary of the Invention

[0005] To improve the versatility and adaptability of the back folding device, this application provides a certificate back folding device.

[0006] This application provides a certificate folding device, which adopts the following technical solution:

[0007] A certificate folding device includes a workbench with a shelf on the workbench and a fixing block on the shelf. The fixing block is located above the shelf. Limiting rod 1 and limiting rod 2 are slidably connected to both sides of the fixing block. Limiting rod 1 and limiting rod 2 slide closer to or further away from the fixing block. The fixing block, limiting rod 1, and limiting rod 2 are joined to form a limiting groove for inserting the certificate. Gear 1 is rotatably connected to the fixing block. Limiting rod 1 has a tooth surface 1, and limiting rod 2 has a tooth surface 2. Tooth surface 1 and tooth surface 2 are located on both sides of gear 1, and both tooth surface 1 and tooth surface 2 mesh with gear 1.

[0008] The shelf has a V-shaped groove, which is located on the center line between the first limiting rod and the second limiting rod and is connected to the limiting groove. A pleated plate is slidably raised and lowered on the worktable. The pleated plate is located above the shelf and the V-shaped groove is for the pleated plate to be inserted. The worktable is provided with a driving component to drive the pleated plate to rise and fall. A reset torsion spring is provided between the first gear and the fixed block.

[0009] By adopting the above technical solution, when in use, the staff inserts the certificate along the opening direction of the limiting groove, and uses the fixing block, limiting rod one, and limiting rod two to abut and limit the three sides of the certificate respectively, thereby achieving the positioning of the certificate. Since the limiting groove adopts an open structure, it only constrains three sides of the certificate, so the width of the certificate is not limited. On the other hand, since limiting rod one and limiting rod two can slide synchronously towards or away from each other through gear one, the length of the limiting groove can be flexibly adjusted according to the actual size of the certificate. Therefore, no matter how the length or width of the certificate changes, it is only necessary to adjust the position of limiting rod one / limiting rod two to adapt to certificates of different specifications and sizes, thus improving the versatility and adaptability of the back-folding device.

[0010] During the back-folding operation, the control drive unit drives the folding plate to press down, and the folding plate squeezes the certificate into the V-groove. Since the V-groove is located on the center line between limit rod one and limit rod two, it ensures that the folding plate can accurately act on the center line of the certificate when it presses down, thus forming a straight and symmetrical fold line. In addition, the setting of the reset torsion spring one provides a stable rebound force for the reset of limit rod one / limit rod two, ensuring the reliability of the three-sided constraint formed by the fixed block and the two side limit rods on the certificate.

[0011] Optionally, the workbench also includes a trolley, the workbench having an inclined surface that slopes downwards away from the shelf, the trolley being located on the side of the inclined surface away from the shelf and below the inclined surface, the lower end of the trolley having casters, and the workbench having a locking mechanism for positioning the trolley.

[0012] By adopting the above technical solution, after the certificate is folded back, it is sent into the inclined plane. Under the action of gravity, the processed certificate slides down the inclined plane and finally falls into the trolley below for centralized collection. After collection, the staff can release the trolley from its locked state and push the trolley to realize the transfer and transportation of the processed products, which facilitates the flow and temporary storage of materials and reduces the labor intensity of manual handling.

[0013] Optionally, the trolley includes a movable seat and a limiting plate disposed on the movable seat. The casters are disposed on the movable seat, the limiting plate is located above the movable seat, and a receiving plate is slidably raised and lowered on the movable seat. The receiving plate is located on the side of the limiting plate near the inclined surface and above the movable seat. An elastic element is provided between the receiving plate and the movable seat.

[0014] By adopting the above technical solution, during the process of the certificates sliding into the trolley, the limiting plate can prevent the certificates from flying out or scattering due to inertia, ensuring that the certificates are neatly stacked in the trolley. At the same time, under the pre-tightening force of the elastic element, the receiving plate can adaptively float according to the number of certificates falling in and the stacking height. Regardless of the stacking height of the certificates, the receiving plate can maintain the optimal receiving posture, which not only ensures the stability of the receiving process, but also helps the certificates to naturally align, forming a neat and tight stack, which is convenient for subsequent counting and transfer.

[0015] Optionally, the trolley is tilted away from the inclined plane, and the receiving plate is provided with a pushing assembly. The pushing assembly includes a first pushing plate, a second pushing plate, a slider, and a second gear. The first pushing plate and the second pushing plate are located above the receiving plate and are slidably connected to the receiving plate. The first pushing plate and the second pushing plate slide closer to or further away from each other. The first pushing plate, the second pushing plate, the receiving plate, and the limiting plate are spliced ​​together to form a receiving groove.

[0016] The slider is located on the side of the limiting plate away from the receiving plate and is slidably connected to the limiting plate. The slider slides closer to or away from the movable seat. The gear two is rotatably connected to the slider. The push plate one and the push plate two are both slidably connected to the slider. The push plate one is provided with a tooth surface three, and the push plate two is provided with a tooth surface four. The tooth surface three and the tooth surface four are located on both sides of the gear two and mesh with the gear two. A reset torsion spring two is provided between the gear two and the slider. A push rod is slidably connected to the worktable. The push rod is located on the side of the push plate one away from the push plate two and slides closer to or away from the push plate one.

[0017] By adopting the above technical solution, when the certificate falls into the receiving groove, it will naturally slide and abut against the limiting plate due to the overall tilt of the trolley. This allows the certificate to be automatically and accurately aligned at the edge of that side. Then, the push rod is moved closer to the push plate one. The push plate one is driven by the meshing transmission of gear two with gear three and gear four to slide and approach each other on the receiving plate. This pushes the certificates that have slid into the receiving groove toward the center, so that the certificates are automatically gathered into a tight and neat stack, reducing the amount of manual sorting work in the later stage.

[0018] Optionally, a foot pedal is provided on the worktable for lifting and sliding, and a transmission plate is slidably connected to the worktable. The transmission plate is connected to the push rod, and the sliding direction of the transmission plate is parallel to the sliding direction of the push rod. A guide groove is provided on the transmission plate, and the guide groove is inclined downward along the sliding direction of the transmission plate. The foot pedal passes through the guide groove. When the foot pedal moves down, the transmission plate drives the push rod to move closer to the push plate.

[0019] By adopting the above technical solution, after the certificate falls into the receiving trough, the worker's hands can continue to focus on the back-folding operation or the loading work. At the same time, by stepping on the foot pedal, the foot pedal moves downward under force and abuts against the inner wall of the guide groove, pushing the transmission plate to drive the push rod to move closer to the push plate, thereby collecting the certificate in the receiving trough. This allows the worker to complete the material collection action without taking their hands off the workbench, improving the overall work efficiency and smoothness, and reducing the safety hazards caused by frequent hand switching.

[0020] Optionally, the limiting plate is provided with a threaded hole for the locking member to be threadedly connected.

[0021] By adopting the above technical solution, the trolley can be firmly locked in the designated position through the threaded connection, which avoids the trolley from shifting due to vibration or impact after the certificate falls into the receiving trough, thus ensuring the stability of the material receiving process.

[0022] Optionally, the workbench is provided with an elastic sheet, which is located above the inclined plane and at the lower end of the inclined plane, and a collection groove is provided on the side of the elastic sheet away from the trolley.

[0023] By adopting the above technical solution, when the certificate passes between the inclined plane and the elastic sheet, the elastic sheet scrapes the surface of the certificate, removing paper scraps, dust or small particles that may adhere to the certificate during the folding and sliding process. This prevents these impurities from being pressed into the inside of the certificate or remaining on the surface during subsequent stacking, thereby reducing scratches, abrasions or indentations caused by friction between certificate layers due to foreign objects. This helps to improve the appearance quality of the finished product. In addition, the scraped impurities and small particles will fall into or be temporarily stored in the collection tank, avoiding secondary flying and falling of impurities, and making it convenient for staff to handle them in one go.

[0024] Optionally, the elastic sheet includes a fixing rod, a mounting rod, and an elastic scraper. The fixing rod is disposed on the worktable, the mounting rod is located on the side of the fixing rod near the shelf, the mounting rod is provided with a locking block, the fixing rod is provided with a locking groove that extends upward through the fixing rod, the elastic scraper is disposed on the side of the mounting rod away from the locking block, and the collection groove is disposed on the elastic scraper.

[0025] By adopting the above technical solution, when it is necessary to clean the impurities collected in the collection tank, the installation rod is moved upward to disengage the locking block from the slot, and the elastic scraper along with the installation rod can be removed from the fixed rod for easy cleaning of the collection tank. After cleaning, the locking block on the installation rod is simply pushed into the slot on the fixed rod to complete the installation of the elastic scraper. No tools are required, and the operation is simple and quick. This not only facilitates daily cleaning of the collection tank but also makes it easier to perform regular maintenance and replacement of the elastic scraper itself, reducing the difficulty and time cost of equipment maintenance.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. Regardless of the length or width of the certificate, simply adjusting the position of limit rod one / limit rod two can accommodate certificates of different sizes, thus improving the versatility and adaptability of the back-folding device;

[0028] 2. After the certificate is folded back, it is sent to the inclined plane and slides down the inclined plane under the action of gravity, and finally falls into the trolley for centralized collection. After collection, the staff can release the trolley from the locked state and push the trolley to realize the transfer and transportation of the processed products, which facilitates the flow and temporary storage of materials and reduces the labor intensity of manual handling.

[0029] 3. During the process of the certificates sliding into the trolley, the limiting plate can prevent the certificates from flying out or scattering due to inertia, ensuring that the certificates are neatly stacked in the trolley. At the same time, under the pre-tightening force of the elastic element, the receiving plate can adaptively float according to the number of certificates falling in and the stacking height, which not only ensures the stability of the receiving process, but also helps the certificates to form a stack, which is convenient for subsequent counting and transfer.

The reset torsion spring 37 is sleeved on the rotating shaft of the gear 264, and the opposite ends of the reset torsion spring 37 are fixedly connected to the gear 264 and the slider 263, respectively.

[0050] Reference Figures 1-9 A push rod 32 is slidably connected to the worktable 1. The push rod 32 is located on the side of the push plate 1 away from the push plate 262 and slides horizontally towards or away from the push plate 261. A limiting cavity 33 is provided on the worktable 1. A foot pedal 34 is slidably raised and lowered on the worktable 1. The foot pedal 34 includes a limiting part 341, a connecting part 342 and a foot pedal 343. The limiting part 341 slides and lowers within the limiting cavity 33. The connecting part 342 is fixed to the horizontal side of the limiting part 341 and extends out of the worktable 1. The foot pedal 343 is located on the outside of the worktable 1 and below the shelf 3. The foot pedal 343 and the connecting part 342 are fixedly connected.

[0051] Reference Figures 1-9 A second sliding groove 35 is provided on the outer side wall of the workbench 1. A transmission plate 36 is slidably connected in the second sliding groove 35. The transmission plate 36 and the end of the push rod 32 away from the push plate 261 are fixedly connected, and the sliding direction of the transmission plate 36 is parallel to the sliding direction of the push rod 32. A guide groove 361 is provided on the outer side wall of the transmission plate 36. The guide groove 361 is inclined downward along the sliding direction of the transmission plate 36. The connecting part 342 passes through the guide groove 361. When the foot block 34 moves down, the transmission plate 36 drives the push rod 32 to move closer to the push plate 261.

[0052] In actual use, after the certificate is processed, it is fed into the inclined plane 16. Under the action of gravity, the processed certificate slides down the inclined plane 16 and falls into the receiving groove 29. Due to the overall tilt of the trolley 2, the certificate will naturally slide towards the limiting plate 22 and stick to it, so that the certificate can be automatically and accurately aligned on that side edge.

[0053] Subsequently, the staff can free up their hands to continue the next step of folding or loading. At the same time, by stepping on the foot pedal 343, the foot pedal 343 moves downward and abuts against the inner wall of the guide groove 361 through the connecting part 342, pushing the transmission plate 36 to drive the push rod 32 to move closer to the push plate 261. The push plate 261 is driven by the meshing of the gear 264 with the tooth surface 30 and the tooth surface 31, driving the push plate 261 and the push plate 262 to slide closer to each other on the receiving plate 24, thereby pushing the certificates that have slid into the receiving groove 29 towards the center, so that the certificates are automatically gathered into a tight and neat stack. This realizes the parallel processing of the operation process and improves the overall operation efficiency and smoothness.

[0054] After the material collection action is completed, the foot is removed. Under the action of the reset torsion spring 37, the push plate 261 pushes the push rod 32 to reset. The push rod 32 then pushes the foot block 34 back to its original position through the guide groove 361 on the transmission plate 36, thus preparing the worker for the next foot collection operation.

[0055] The implementation principle of a certificate folding device in this application embodiment is as follows:

[0056] In use, the staff inserts the certificate along the opening direction of the limiting groove 7. The fixing block 4, limiting rod 5 and limiting rod 6 respectively abut and limit the three edges of the certificate, thereby achieving the positioning of the certificate. Since the limiting groove 7 adopts an open structure, it only constrains three sides of the certificate, so the width of the certificate is not limited. On the other hand, since the limiting rod 5 and the limiting rod 6 can slide synchronously towards or away from each other through the gear 12, the length of the limiting groove 7 can be flexibly adjusted according to the actual size of the certificate. Therefore, no matter how the length or width of the certificate changes, it is only necessary to adjust the position of the limiting rod 5 / limiting rod 6 to adapt to certificates of different sizes, which improves the versatility and adaptability of the back-folding device.

[0057] During the back folding operation, the control drive 10 drives the folding plate 9 to press down, and the folding plate 9 squeezes the certificate into the V-groove 8. Since the V-groove 8 is located on the center line between the first limit rod 5 and the second limit rod 6, it ensures that the folding plate 9 can accurately act on the center line of the certificate when it presses down, thereby forming a straight and symmetrical fold line. In addition, the setting of the reset torsion spring 15 provides a stable rebound force for the reset of the first limit rod 5 / second limit rod 6, ensuring the reliability of the three-sided constraint formed by the fixing block 4 and the two side limit rods on the certificate.

[0058] 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.
