Description

Technical Field

[0001] This utility model relates to the field of document scanning device technology, and in particular to an archival document scanning device. Background Technology

[0002] To facilitate rapid data entry of archival documents and improve entry efficiency, scanning devices are typically used. When scanning, the document is usually placed directly on the bottom of the scanner, its position adjusted, and then scanned. After scanning, the scanned document is removed, and another document to be scanned is placed in and its position adjusted. However, this method of data entry can lead to errors if the document is wrinkled. Therefore, this paper proposes an archival document scanning device to address these issues.

[0003] The following solution, disclosed in publication number CN222423749U, includes a worktable; a scanner fixedly mounted on the top of the worktable; two supports, one fixedly mounted on the top of the worktable and the other slidably connected to the worktable; a positioning mechanism and a control mechanism, comprising two sets of positioning mechanisms that cooperate with the supports and control mechanism respectively. The positioning mechanism is used to position the supports. In this invention, the top and bottom of the document are clamped by two clamping rods, and then the lower support is pulled down to move downwards. This straightens the document, reduces wrinkles, and fixes the document, increasing its stability during scanning and reducing the probability of input errors.

[0004] While the aforementioned patent can smooth out the files, most files are made of paper, and smoothing them out directly can easily cause creases, which can lead to data entry errors. Utility Model Content

[0005] This utility model discloses an archival document scanning device, which aims to solve the technical problems in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An archival document scanning device includes a straightening unit and a smoothing unit:

[0008] The straightening unit includes a table, on which files are placed, a movable frame is slidably mounted on the top of the table, a connecting plate is fixedly mounted on one side of the movable frame, a hydraulic cylinder is fixedly mounted inside the movable frame, a flattening frame is fixedly mounted on the top of the hydraulic cylinder, a scanner is fixedly mounted on the top of the table, an electric telescopic rod is fixedly mounted on one side of the connecting plate, a slant plate is hinged to one end of the flattening frame, a roller is rotatably mounted on one end of the slant plate, and a torsion spring is fixedly mounted on the top of the roller.

[0009] The smoothing unit includes a motor, a threaded rod fixedly installed at the output end of the motor, a threaded sleeve threadedly installed on the outer wall of the threaded rod, a sliding rod slidably installed inside the threaded sleeve, a spring telescopic plate fixedly installed at the bottom of the threaded sleeve, and a smoothing rod rotatably installed at the bottom of the spring telescopic plate.

[0010] In a preferred embodiment, the table body has a through groove inside, and the connecting plate is slidably installed with the table body through the through groove.

[0011] In a preferred embodiment, a mounting plate is fixedly installed at the bottom of the table body, and the end of the electric telescopic rod away from the connecting plate is fixedly installed on the connecting plate.

[0012] In a preferred embodiment, the outer wall of the roller is tightly fitted onto the file, and the other end of the torsion spring away from the inclined plate is fixedly mounted on the flattening frame.

[0013] In a preferred embodiment, both ends of the slide rod are fixedly installed with the flattening frame, and one end of the threaded rod is rotatably installed with the flattening frame.

[0014] In a preferred embodiment, the top of the file is fitted tightly against the smoothing rod, and the motor output is rotatably mounted to the flattening frame.

[0015] As can be seen from the above, the document scanning device provided by this utility model has the following technical effects.

[0016] Firstly, the document is placed at the bottom of the scanner, and then the electric telescopic rod retracts, moving the moving frame, connecting plate, and flattening frame together to the top of the document. Then, the hydraulic cylinder retracts, changing the angle of the inclined plate, pressing the rollers onto the document, and moving and rolling to both sides, thus straightening the document. This process is fully automated and first straightens the document, initially smoothing out any wrinkles.

[0017] Secondly, when the hydraulic cylinder retracts downwards, the smoothing rod will also press against the file. At the same time, the smoothing rod is tightly engaged with the file through the elasticity of the spring telescopic plate. Then, the motor drives the threaded rod to rotate, which drives the threaded sleeve to move, thereby moving the smoothing rod to smooth the file. Smoothing after straightening can avoid creases caused by direct smoothing. Attached Figure Description

[0025] Reference Figures 1-4 An archival document scanning device includes a straightening unit 100 and a smoothing unit 200:

[0026] The straightening unit 100 includes a table 101, on which a file 102 is placed. A movable frame 103 is slidably mounted on the top of the table 101. A connecting plate 104 is fixedly mounted on one side of the movable frame 103. A hydraulic cylinder 105 is fixedly mounted inside the movable frame 103. A flattening frame 106 is fixedly mounted on the top of the hydraulic cylinder 105. A scanner 107 is fixedly mounted on the top of the table 101. An electric telescopic rod 108 is fixedly mounted on one side of the connecting plate 104. The electric telescopic rod 108 can drive the entire smoothing device to move. When the smoothing is finished and scanning is completed, the smoothing device is retracted so as not to cause obstruction during scanning. A slant plate 109 is hinged to one end of the flattening frame 106. A roller 110 is rotatably mounted on one end of the slant plate 109. A torsion spring 111 is fixedly mounted on the top of the roller 110 to provide an inward rebound force, which facilitates the slant plate 109 to rebound and reset.

[0027] The smoothing unit 200 includes a motor 201, a threaded rod 202 fixedly installed at the output end of the motor 201, a threaded sleeve 203 threadedly installed on the outer wall of the threaded rod 202, a slide rod 204 slidably installed inside the threaded sleeve 203, a spring telescopic plate 205 fixedly installed at the bottom of the threaded sleeve 203, and a smoothing rod 206 rotatably installed at the bottom of the spring telescopic plate 205.

[0028] In this embodiment, when the hydraulic cylinder 105 retracts downward, the smoothing rod 206 also presses against the file 102. At the same time, the smoothing rod 206 is tightly engaged with the file 102 through the elasticity of the spring telescopic plate 205. Then, the motor 201 drives the threaded rod 202 to rotate, which drives the threaded sleeve 203 to move, thereby driving the smoothing rod 206 to move and smooth the file 102. Smoothing after straightening can avoid creases caused by direct smoothing.

[0029] In a preferred embodiment, a through groove is provided inside the table body 101, and the connecting plate 104 is slidably installed with the table body 101 through the through groove.

[0030] In this embodiment, the through groove allows the connecting plate 104 to slide easily inside the table body 101, making it more convenient for the electric telescopic rod 108 to move the connecting plate 104.

[0031] In a preferred embodiment, a mounting plate is fixedly installed on the bottom of the table body 101, and the end of the electric telescopic rod 108 away from the connecting plate 104 is fixedly installed on the connecting plate 104.

[0032] In this embodiment, by installing a plate to stabilize the fixed end of the electric telescopic rod 108, the electric telescopic rod 108 is driven more stably.

[0033] In a preferred embodiment, the outer wall of the roller 110 is tightly fitted to the file 102, and the other end of the torsion spring 111 away from the inclined plate 109 is fixedly mounted on the flattening frame 106.

[0034] In this embodiment, the file 102 is straightened by the pressure of the roller 110 and its tendency to move outward.

[0035] In a preferred embodiment, the two ends of the slide bar 204 are fixedly installed with the flattening frame 106, and one end of the threaded rod 202 is rotatably installed with the flattening frame 106.

[0036] In this embodiment, the rotation of the threaded sleeve 203 is restricted by the slide bar 204, which can prevent excessive friction between the threaded rod 202 and the threaded sleeve 203 from causing the threaded rod 202 to directly drive the threaded sleeve 203 to rotate.

[0037] In a preferred embodiment, the top of the file 102 is fitted tightly against the smoothing bar 206, and the output end of the motor 201 is rotatably mounted to the flattening frame 106.

[0038] In this embodiment, the smoothing rod 206 is smoothed by moving the file 102. Since the smoothing rod 206 is already taut, no creases will be produced when smoothing it.

[0039] Working principle: When in use, first lift the hydraulic cylinder 105, then lift the flattening frame 106 and other structures together, and then drive the connecting plate 104, the moving frame 103 and the flattening frame 106 together to move away from the bottom of the scanner 107 through the electric telescopic rod 108.

[0040] The document is placed at the bottom of the scanner 107, and then retracted by the electric telescopic rod 108, which moves the moving frame 103, connecting plate 104 and flattening frame 106 together to the top of the document 102. Then, the hydraulic cylinder 105 retracts, which changes the angle of the inclined plate 109. The roller 110 presses on the document 102 and moves and rolls to both sides, making the document 102 taut.

[0041] When the hydraulic cylinder 105 retracts downward, the smoothing rod 206 will also press against the file 102. At the same time, the smoothing rod 206 will be tightly engaged with the file 102 through the elasticity of the spring telescopic plate 205. Then, the motor 201 will drive the threaded rod 202 to rotate, which will drive the threaded sleeve 203 to move, thereby driving the smoothing rod 206 to move and smooth the file 102.

[0042] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Substitutions may include replacements for some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the scope of protection of this utility model.
