[0008] The moving mechanism includes a second electric push rod and an electric slide rail. The second electric push rod is fixedly installed on the top front side of the rear support frame, and the free end of the second electric push rod is fixedly installed with an electric slide rail.

[0009] The flattening component includes a push plate, a rotating roller, a coil spring, a pressing belt, a first spring, and a pressure roller. The push plate is fixedly installed at the bottom of the moving end of the electric slide rail. The push plate is L-shaped. A rotating roller is rotatably installed inside the push plate, and the rotating roller is located in the lower half of the push plate. A coil spring is provided at the connection between the rotating roller and the push plate. A pressing belt is wound around the surface of the rotating roller. A first spring is fixedly installed inside the push plate. A U-shaped plate is fixedly installed at the free end of the first spring. The U-shaped plate is in contact with the inner wall of the push plate, and a pressure roller is rotatably installed inside the U-shaped plate.

One end of the second spring is connected to the positioning block, and the other end of the second spring is connected to the inner wall of the sliding groove.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention uses a moving mechanism to move two sets of flattening components that are attached to the middle of the paper document. These components move to the edge of the document, pressing and flattening the rolled edge. As the moving mechanism moves the two sets of flattening components in opposite directions, the pressure belts on the two sets of rotating rollers unfold. The pressure belts are pressed against the edge of the paper document by the pressure rollers until the rollers separate from the document. The pressure belts press down on one side of the document, and a pushing mechanism rotates its rotating end. The pressure plate is pushed over the top surface of the pressure belt, where it flattens and presses the paper document, ensuring that the rolled edges of the paper document can be quickly flattened during scanning, facilitating the scanning process. The positioning cylinder is attracted by the internal electromagnet of the placement platform, causing the positioning block to slide out of the groove and contact the surface of the paper document, thereby pressing and limiting it to prevent the paper document from shifting as the flattening component moves. After the pressing and limiting of the positioning cylinder stops, the moving pressure plate can push the positioning cylinder to roll away from the top of the paper document.

[0025] An auxiliary device for scanning archival documents includes a base 1, which comprises a support platform 101, a rear support frame 102, and a support plate 103. The rear support frame 102 is fixedly installed on the rear side of the support platform 101, and the support plate 103 is fixedly installed on the top of the support platform 101. An operating table is provided on the front side of the support platform 101, and a liftable worktable 2 is installed on the top of the support platform 101. A moving mechanism 3 is fixedly installed on the top of the rear support frame 102. The moving end of the moving mechanism 3 consists of two sets that can move in opposite directions. A flattening component 4 is fixedly installed at the bottom of the moving end of the moving mechanism 3, and the pressing end at the bottom of the flattening component 4 can... The paper documents on the worktable 2 are attached to the pressing end of the flattening part 4 after being rolled up and unfolded. The top of the support plate 103 is fixedly installed with a pushing mechanism 5. The inside of the support plate 103 is slidably installed with a pressing plate 6. The pressing plate 6 is made of transparent material and passes through the inside of the pushing mechanism 5 and is attached to its rotating end. The bottom of the pressing plate 6 is attached to the paper documents on the worktable 2. The top of the worktable 2 is placed with a positioning cylinder 7. The top of the support table 101 is installed with a scanning mechanism 8. The scanning mechanism 8 consists of a robotic arm and a scanner. The robotic arm is fixedly installed on the top of the base 1, and the scanner is set at the end of the robotic arm.

[0026] Specifically, the operation and coordination of each component of the device are controlled and preset through the operating table. The worktable 2 moves the paper file upward so that it contacts the flattening component 4. The moving mechanism 3 moves the flattening component 4 so that it moves to fit the surface of the paper file and flattens its rolled edges. The rotating end of the pushing mechanism 5 rotates and pushes the pressure plate 6 to slide so that the pressure plate 6 passes through the flattening component 4 and presses and flattens the paper file. The positioning cylinder 7 presses and limits the paper file. The scanning mechanism 8 scans and backs up the paper file to maintain the digitized archive.

[0027] The workbench 2 includes a first electric push rod 201, a storage platform 202, a slide rod 203, and a storage box 204. The first electric push rod 201 is fixedly installed on the top of the support platform 101. The storage platform 202 is fixedly installed at the top of the first electric push rod 201. An electromagnet is provided inside the storage platform 202. The slide rod 203 is fixedly installed at the bottom of the storage platform 202. The slide rod 203 is slidably inserted into the top of the support platform 101. The storage box 204 is fixedly installed on the front side of the storage platform 202.

[0028] Specifically, the first electric push rod 201 drives the storage platform 202 to move up and down, controlling the paper file to fit against the bottom pressing end of the push flat part 4. The slide rod 203 makes the movement of the storage platform 202 more stable, and the storage box 204 is used to put in and take out the positioning cylinder 7.

[0029] The moving mechanism 3 includes a second electric push rod 301 and an electric slide rail 302. The second electric push rod 301 is fixedly installed on the top front side of the rear support frame 102. The free end of the second electric push rod 301 is fixedly installed with the electric slide rail 302. The electric slide rail 302 consists of a motor, a slide rail, a bidirectional screw, and a slider. One end of the slide rail is equipped with a motor. The bidirectional screw is rotatably installed inside the slide rail. The output end of the motor is connected to the bidirectional screw. Two sets of sliders are threaded on the surface of the bidirectional screw, and the sliders are slidably installed inside the slide rail.

[0030] Specifically, the second electric push rod 301 pushes the electric slide rail 302 to move, thereby controlling the sliding of the flattening component 4 on the surface of the paper document in the back-and-forth direction. The motor of the electric slide rail 302 drives the bidirectional screw to rotate, and the bidirectional screw drives the two sets of sliders to move against the inner wall of the slide rail, thereby controlling the two sets of flattening components 4 to move in opposite directions on the surface of the paper document.

[0031] The flattening component 4 includes a push plate 401, a rotating roller 402, a coil spring 403, a pressing belt 404, a first spring 405, and a pressure roller 406. The push plate 401 is fixedly installed on the bottom of the slider. The push plate 401 is L-shaped. The rotating roller 402 is rotatably installed inside the push plate 401, and the rotating roller 402 is located in the lower half of the push plate 401. A coil spring 403 is provided at the connection between the rotating roller 402 and the push plate 401. One end of the coil spring 403 is connected to the rotating roller 402, and the other end of the coil spring 403 is connected to the push plate 406. The plates 401 are connected, and the surface of the roller 402 is wound with a pressing belt 404. The two ends of the pressing belt 404 are respectively connected to two sets of rollers 402. The upper surface of the pressing belt 404 is smooth and its lower surface is rough. A first spring 405 is fixedly installed inside the push plate 401. A U-shaped plate is fixedly installed at the free end of the first spring 405. The U-shaped plate is in contact with the inner wall of the push plate 401, and a pressure roller 406 is rotatably installed inside the U-shaped plate. The pressure roller 406 is in contact with the top of the pressing belt 404.

[0032] Specifically, the push plate 401 moves from the center of the paper document to the edge, thus avoiding direct pressure on the rolled-up edge of the paper document and causing damage. The coil spring 403 pulls the unfolded roller 402 to rotate, and the pressure belt 404 is rolled back to the surface of the roller 402. The first spring 405 pushes the U-shaped plate to move down against the inner wall of the push plate 401, so that the pressure roller 406 presses the pressure belt 404, and the pressure belt 404 flattens the edge of the paper document.

[0033] The pushing mechanism 5 includes a fixed plate 501, a pushing roller 502, a transmission wheel 503, a servo motor 504, and a drum 505. The fixed plate 501 is fixedly installed on the top of the support plate 103. The pushing roller 502 is rotatably installed inside the fixed plate 501. The surface of the pushing roller 502 is provided with anti-slip blocks. The transmission wheel 503 is fixedly sleeved on one end of the pushing roller 502. There are two sets of pushing rollers 502 and transmission wheels 503, and the two sets of pushing rollers 502 and transmission wheels 503 are symmetrically arranged about the pressing plate 6. The two sets of pushing rollers 502 are respectively attached to the upper and lower sides of the pressing plate 6. The two sets of transmission wheels 503 are meshed. The servo motor 504 is located on one side of the fixed plate 501, and the output end of the servo motor 504 passes through the surface of the fixed plate 501 and is connected to one end of the pushing roller 502.

[0034] Specifically, the servo motor 504 drives the push roller 502 to rotate, and the push roller 502 pushes the pressure plate 6 in contact with its surface to move. Through the meshing of two sets of transmission wheels 503, when the push roller 502 connected to the servo motor 504 rotates, it drives the other set of push rollers 502 to rotate synchronously.

[0035] Roller 505 is rotatably installed inside support plate 103. Pressure plate 6 is slidably installed inside support plate 103. There are two sets of rollers 505, and the two sets of rollers 505 are respectively attached to the upper and lower sides of pressure plate 6.

[0036] Specifically, when the pressure plate 6 is pushed by the push roller 502 through the roller 505, it can move stably through the interior of the support plate 103.

[0037] The positioning cylinder 7 includes a cylinder body 701, a slide groove 702, a second spring 703, and a positioning block 704. The slide groove 702 is formed on the surface of the cylinder body 701. The positioning block 704 is slidably installed inside the slide groove 702. One end of the second spring 703 is connected to the positioning block 704, and the other end of the second spring 703 is connected to the inner wall of the slide groove 702. The positioning block 704 is correspondingly arranged with the electromagnet of the placement platform 202.

[0038] Specifically, through the circular cross-section of the cylinder 701, when the second spring 703 pulls the positioning block 704 into the slide groove 702, the positioning cylinder 7 can be easily pushed by the pressure plate 6 and rolled into the storage box 204. The positioning block 704 is attracted by the electromagnet of the storage platform 202 and slides out of the slide groove 702, thereby restricting the rolling of the cylinder 701. The positioning cylinder 7 is used to press and limit the paper file.

[0039] In summary: When using this utility model, the operator places the paper document to be scanned on the platform 202 and presses the positioning cylinder 7 onto the surface of the paper document. The electromagnet of the platform 202 is energized, causing it to attract the positioning block 704. This pulls the positioning block 704 out of the groove 702 and into contact with the surface of the paper document, pressing and limiting its position. The first electric push rod 201 drives the platform 202 upward along the guide rod 203 until the paper document is in contact with the pressing belt 404. This then drives the second electric push rod 301 to activate the electric... The slide rail 302 moves backward, causing the flattening component 4 to move from the center of the paper document to the edge, preventing the flattening component 4 from directly pressing on the rolled edge of the paper document. Then, the electric slide rail 302 is driven to drive the two sets of push plates 401 to move in opposite directions. The pressure belt 404 located on the two sets of rotating rollers 402 is unfolded. The first spring 405 pushes the pressure roller 406 to adhere to the top of the pressure belt 404, so that the rough lower surface of the pressure belt 404 presses the edge of the paper document, flattening the rolled edge, until the push plate 401 separates from the paper document and is located on the two sides of the storage platform 202. On the side, the drive servo motor 504 drives a set of push rollers 502 to rotate. Relying on the meshing between the two sets of transmission wheels 503, it drives another set of push rollers 502 to rotate synchronously, thereby pushing the pressure plate 6 between the two sets of push rollers 502 to slide forward. When the pressure plate 6 moves above the pressure belt 404, the first electric push rod 201 is driven again to move the placement platform 202 up a certain distance, and the electromagnet of the placement platform 202 is stopped from being energized, so that the pressure belt 404 presses tightly against the edge of the paper file, limiting and fixing it. The pressure plate 6 and the pressure belt 404 are light The upper surface of the slide contacts the paper file, and at the same time, the second spring 703 pulls the positioning block 704 back into the slide groove 702. As the pressure plate 6 moves, it completely covers the top surface of the paper file, flattening its rolled-up edges. At the same time, the pressure plate 6 pushes the positioning cylinder 7 to roll on the paper file until it falls into the storage box 204. The robotic arm drives the scanner to scan the paper file that has been flattened by the transparent pressure plate 6. After the backup is completed, the components of the device are reset, the staff replaces the paper file and presses the positioning cylinder 7 on it again to scan the next paper file.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
