[0002] Archives, a Chinese term, refers to various forms of original records with preservation value directly formed in various social activities of people. Original recordability is its essential attribute. In ancient China, archives had different appellations in different dynasties. In the Shang Dynasty, they were called "books", in the Zhou Dynasty, they were called "zhong", in the Qin and Han dynasties, they were called "classics", and after the Han and Wei dynasties, they were called "documents", "document files", "official documents", "archives", "records", and "account books". After the Qing Dynasty, the term "archives" was mostly used, and now it is uniformly called "archives".

[0003] And digital processing of archives refers to the process of converting traditional paper archives, photos, films and other physical archives into electronic documents or digital images through technical means such as scanning by a scanner and shooting, and storing, managing and utilizing them by using computer technology, so as to improve the protection of archives. The scanner used to scan paper archives, photos, films and convert them into electronic documents or digital images can be called a scanning device for digital processing of archives.

[0004] However, when using this scanning device for digital processing of archives, it is necessary to manually place each piece of archive paper on the scanning table for scanning operations, and this process is rather cumbersome. Therefore, it does not meet the existing requirements, and for this reason, we propose a scanning device for digital processing of archives. Content of the Utility Model

[0005] The purpose of the utility model is to provide a scanning device for digital processing of archives, so as to solve the problems proposed in the above background technique that when using this scanning device for digital processing of archives, it is necessary to manually place each piece of archive paper on the scanning table for scanning operations, and this process is rather cumbersome.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A scanning device for digital processing of archives, including a scanning table, a fixed frame is arranged outside the scanning table, a row of teeth is fixedly arranged on one side inside the fixed frame, a concave-shaped outer shell is arranged outside the row of teeth and is slidably connected thereto, a stepping motor is fixedly installed on one side inside the concave-shaped outer shell, the output shaft of the stepping motor is connected to a transmission rotating shaft through a coupling, and a gear meshing with the row of teeth is fixedly sleeved on the outer surface of the transmission rotating shaft.

[0007] A long rotating shaft is arranged above the transmission rotating shaft, and the transmission rotating shaft and the long rotating shaft are meshed through a synchronous chain.

[0008] A first bevel gear is fixedly sleeved on one side of the outer surface of the long rotating shaft. The first bevel gear meshes with a second bevel gear. The shaft of the second bevel gear is connected to a lifting threaded rod. An internal threaded sleeve is provided on the upper side of the outer surface of the lifting threaded rod and connected to it through a threaded structure. An adsorption fixing head that is slidably connected to the concave outer shell is fixedly provided at the rear end of the internal threaded sleeve.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention allows a stack of archival papers to be placed on the upper surface of the scanning table during use.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] The scanning stage 1 (model ET16), stepper motor 5 (model DM542), and lifting threaded rod 12 (model M08) mentioned in this utility model can all be obtained from the market or through private customization.

[0022] Please see Figures 1 to 3 An embodiment of this utility model provides: a document digitization processing scanning device, including a scanning table 1, a fixed frame 15 on the outer side of the scanning table 1, a toothed rack 2 fixedly provided on one side inside the fixed frame 15, a concave outer shell 3 slidably connected to the toothed rack 2 on the outer side of the toothed rack 2, a stepper motor 5 fixedly installed on one side inside the concave outer shell 3, the output shaft of the stepper motor 5 is connected to a transmission shaft 6 through a coupling, and a gear 7 that meshes with the toothed rack 2 is fixedly sleeved on the outer surface of the transmission shaft 6.

[0023] A long shaft 8 is provided above the transmission shaft 6, and the transmission shaft 6 and the long shaft 8 are meshed by a synchronous chain 9;

[0024] A first bevel gear 10 is fixedly sleeved on one side of the outer surface of the long rotating shaft 8. The first bevel gear 10 meshes with a second bevel gear 11. The shaft of the second bevel gear 11 is connected to a lifting threaded rod 12. An internal threaded sleeve 13 is provided on the upper side of the outer surface of the lifting threaded rod 12 and is connected to it by a threaded structure. An adsorption fixing head 14 is fixedly provided at the rear end of the internal threaded sleeve 13 and is slidably connected to the concave outer shell 3.

[0025] A scanner 16 is installed above the scanning table 1, and the scanning table 1 and the scanner 16 are fixed together by screws. When the equipment is needed, a stack of documents is placed on the upper surface of the scanning table 1, and the scanner 16 scans the documents at the top. After the documents at the top are scanned, the stepper motor 5 is started. The stepper motor 5 can drive the transmission shaft 6 connected to it and the gear 7 fixedly sleeved on the outer surface of the transmission shaft 6 to rotate. When the gear 7 inside the concave housing 3 rotates, under the transmission of the gear structure of the gear rack 2 fixed inside the fixed frame 15, the entire concave housing 3 will move with the rotation of the gear 7. At this time, the concave housing 3 is moved towards the top of the scanning table 1.

[0026] During the rotation of the transmission shaft 6, the long shaft 8 connected in series with it via the synchronous chain 9 will rotate together. The rotating long shaft 8 can drive the first bevel gear 10 fixedly sleeved on the outer surface of the long shaft 8 and the second bevel gear 11 meshing with it to rotate together. When the second bevel gear 11 rotates, the lifting threaded rod 12 connected to the shaft of the second bevel gear 11 will rotate synchronously. Since the inner threaded sleeve 13 installed on the outer surface of the lifting threaded rod 12 through the threaded structure is fixed to the adsorption fixing head 14, the inner threaded sleeve 13 itself cannot rotate.

[0027] When the lifting threaded rod 12 rotates, the internal threaded sleeve 13, which is threadedly connected to it but cannot rotate on its own, will move up and down under the drive of the threaded structure. When the concave outer shell 3 moves upward toward the scanning table 1, the internal threaded sleeve 13 will move downward accordingly. During the downward movement of the internal threaded sleeve 13, the suction fixing head 14, which is fixed to the internal threaded sleeve 13, will also move downward. As the suction fixing head 14 moves, it will contact the topmost document and suction and fix it. Then, the output shaft of the reverse-drive stepper motor 5 can move the suction fixing head 14 upward simultaneously from above the scanning table 1 to remove the topmost document. Through the above technical solution, the equipment can automatically scan a large number of documents, making the equipment easier to use.

[0028] With the transmission mechanism described above, a single power source, stepper motor 5, can simultaneously move the suction and fixing head 14 downwards while driving the concave outer shell 3 to move in parallel. This structure can reduce the production cost of the structure and quickly identify the source of the power failure when the structure experiences a power failure.

[0029] Below the suction head 14 is a scanning document placement stage 4, and the surface of the scanning document placement stage 4 facing the scanning stage 1 is fixed to the scanning stage 1. When the suction head 14 returns to its original position, the fixing of the document paper is released, and the removed document paper can be piled on the upper surface of the scanning document placement stage 4.

[0030] A guide rod is fixed inside the concave outer shell 3 at the rear of the adsorption fixing head 14. A guide sleeve is slidably connected to the upper side of the outer surface of the guide rod, and the surface of the guide sleeve facing the adsorption fixing head 14 is fixed to the adsorption fixing head 14. The guide rod and the guide sleeve can ensure the stability of the adsorption fixing head 14 when it moves up and down.

[0031] A metal guide rod is fixed inside the fixed frame 15 at the rear of the toothed rack 2, and the metal guide rod moves laterally through the rear end of the concave shell 3; the stability of the concave shell 3 moving in parallel can be ensured by the metal guide rod moving laterally through the rear end of the concave shell 3.

[0032] A protective cover plate is provided at the rear of the stepper motor 5 on the outer surface of the concave housing 3, and the concave housing 3 and the protective cover plate are fixed together by screws; the protective cover plate can protect the stepper motor 5, and when the stepper motor 5 fails, the protective cover plate can be removed to perform maintenance work on the stepper motor 5.

[0033] 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.
