Description

Technical Field

[0001] This invention relates to the field of intelligent office equipment technology, specifically to a processing rack for an electronic document conversion device. Background Technology

[0002] With the advancement and development of science and technology, society has entered the information age. Computer applications are indispensable in the construction of many fields, and media such as disks, magnetic tapes, and optical discs are increasingly used. This emergence has accelerated the transformation of archival formats. Previously, archives were primarily paper-based. While paper archives could be stored for a long time, they also had drawbacks such as inconvenience in retrieval and high time and effort costs. With the advent of the information age and the further popularization of office automation, electronic archives have become increasingly important in archival management. It can be said that electronic archives have become the main form of archival management at present.

[0003] To better adapt to the management of electronic archives, researchers have designed devices to convert paper documents into electronic files. For example, patent document CN116423998A discloses a paper document processing device, which includes an integrated paper conveying device, an image acquisition component, and a coding device. The integrated paper conveying device includes two anti-deviation conveying sections with an image acquisition gap between them. The image acquisition component is fixed above and below the image acquisition gap via a conveyor frame, and the coding device is fixed above and below the output end of the latter anti-deviation conveying section via a conveyor frame. The image acquisition component is used to acquire images of both the top and bottom sides of the paper during the paper conveying process, and the coding device is used to code the pages containing characters on the corresponding paper based on the acquired images. This device has the advantage of quickly and efficiently converting paper documents into electronic documents. However, due to its horizontal planar structure, it suffers from technical problems such as a long paper conveying path that is prone to paper jams, a large device size, and a large space occupation. In addition, the device is also enclosed in a casing during actual use. This means that the anti-deviation conveyor section, image acquisition components, and coding device are all enclosed inside. If a paper jam occurs, the casing needs to be removed to handle it. Moreover, the paper is easily damaged during the process, and the original content on the paper is lost, affecting the integrity of the converted electronic document. Summary of the Invention In view of the shortcomings and defects of the prior art, the present invention proposes a processing rack for electronic document conversion equipment. The purpose is to solve the technical problems of existing equipment, such as long paper transport path which is prone to paper jams, large equipment size, inconvenience in handling paper jams, and easy damage to paper and loss of original content when handling paper jams, by designing a shorter and openable inclined paper transport channel on the processing rack.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A processing rack for an electronic document conversion device includes a frame body. The frame body has a right-angled triangular structure. The hypotenuse of the frame body forms an openable inclined paper feeding channel through a fixed paper feeding base plate and a rotatable paper feeding cover plate at the upper end. The lower end of the paper feeding cover plate is hinged to the lower end of the paper feeding base plate. A limiting component for limiting the rotation angle of the paper feeding cover plate is provided between the paper feeding cover plate and the paper feeding base plate. A positioning guide pin and a positioning guide pin hole are provided between the middle of the paper feeding cover plate and the middle of the paper feeding base plate. A fastener is provided between the upper end of the paper feeding cover plate and the upper end of the paper feeding base plate. By unfastening the fastener and rotating the paper feeding cover plate, the inclined paper feeding channel can be opened. The frame is provided with a paper feeding station for installing a paper feeding device, a paper feeding station for installing a paper feeding roller assembly, a scanning station for installing a scanning device, and a coding station for installing a coding device on its inclined side. The paper feeding stations are arranged at intervals along the inclined direction of the inclined paper feeding channel. The paper feeding station is located at the upper part of the inclined paper feeding channel, the coding station is located at the lower part of the inclined paper feeding channel, and the scanning station is located below the paper feeding station and the coding station, respectively.

[0005] The limiting component is located in the lower middle part of one side of the paper feeding base plate, and includes a limiting rod and a limiting pin. The limiting pin is fixed on the side wall of the paper feeding base plate. One end of the limiting rod is hinged to the side wall of the paper feeding cover plate, and the other end is provided with a limiting groove along the length direction. The limiting pin is located in the limiting groove.

[0006] The minimum length of the inclined paper feed channel is 650mm, and the inclination of the inclined paper feed channel is 30-60 degrees.

[0007] The frame includes a base, on which two right-angled triangular side plates are symmetrically fixed. The side triangular plates are fixed together by a support rod. The paper feed bottom plate and the paper feed cover plate are both installed on the hypotenuses of the two side triangular plates.

[0008] The paper feeding station is provided with corresponding paper feeding holes and paper separating holes. The paper feeding holes are located on the upper part of the paper feeding base plate for installing the paper feeding rollers in the paper feeding device, and the paper separating holes are located on the upper part of the paper feeding cover plate for installing the separating rollers in the paper feeding device.

[0009] The paper feeding station is provided with several corresponding main paper feeding holes and secondary paper feeding holes. The main paper feeding holes are opened in groups at intervals on the paper feeding base plate for installing the drive wheel group in the paper feeding roller group; the secondary paper feeding holes are opened in groups at intervals on the paper feeding cover plate for installing the driven wheel group in the paper feeding roller group.

[0010] The scanning station is equipped with scanning windows corresponding to the scanning device, which are respectively set on the paper feed base plate and the paper feed cover plate.

[0011] The coding station is equipped with coding windows corresponding to the coding device, which are respectively set on the paper feed base plate and the paper feed cover plate.

[0012] The upper end of the inclined paper feeding channel is provided with an upper station for installing a paper feed tray. The upper station is a bent part of the upper end of the paper feeding base plate with a horizontal bend. The upper station has an insertion hole for inserting the paper feed tray. The lower end of the inclined paper feeding channel is provided with a lower station for installing a paper receiving tray through the frame. The lower station has a sliding groove for sliding the paper receiving tray on the lower station.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention forms an openable and closable inclined paper feeding channel by setting a fixed paper feeding base plate on the inclined side of the processing frame and a rotatable paper feeding cover plate at the top, making the paper feeding channel inclined and openable. The inclined paper feeding channel significantly shortens its length and utilizes the downward gravity of the paper for transport, effectively shortening the paper transport path and making the paper transport smoother and less prone to jamming. The openable structure allows the paper feeding channel to be opened or closed. Even if a paper jam occurs, the inclined paper feeding channel can be opened by unfastening the fastener and rotating the paper feeding cover plate, fully exposing the inclined paper feeding channel and the jammed paper inside. This facilitates quick removal of jammed paper and avoids paper damage and loss of original content. It has the advantages of fast processing speed, high efficiency, low difficulty, no paper damage, and no content loss. In addition, by setting up paper feeding stations, paper feeding stations, scanning stations and coding stations along the inclined side of the processing rack, the various action mechanisms can be reasonably and centrally arranged on the rack along the inclined paper feeding channel, which can not only realize the effective conversion of electronic documents, but also has the advantages of reducing equipment size and space occupation.

[0014] 2. This invention facilitates the installation of paper feed rollers and separation rollers by providing paper feed holes and paper separation holes at the paper feeding station; facilitates the installation of drive roller assemblies and driven roller assemblies by providing main paper feed holes and secondary paper feed holes at the paper feeding station; facilitates the installation of paper images by providing a scanning window at the scanning station; and facilitates the coding of paper pages by providing a coding window at the coding station. With this specific structure, only parts of the paper feed holes, paper separation holes, drive roller assemblies, and driven roller assemblies extend into the inclined paper feeding channel and act on the paper. The entire inclined paper feeding channel is relatively smooth and flat, which not only helps to minimize paper jams but also minimizes paper damage when jams occur.

[0015] 3. This invention uses a limiting component to limit the rotation angle of the paper feed cover, facilitating the opening of the inclined paper feed channel to handle paper jams while preventing excessive rotation from affecting the stability of the processing rack. Furthermore, the limiting component also has the advantages of simple structure, convenient operation, and stable rotation.

[0016] 4. This invention allows for a minimum length of 650mm for the inclined paper feed channel, resulting in a smaller device size and further reducing overall device volume. Setting the inclination of the inclined paper feed channel to 30-60 degrees improves the smoothness of paper movement and reduces the chance of paper jams. Conversely, if the inclination is less than or greater than this, paper jams during feeding or paper stacking during output will occur.

[0017] 5. The present invention facilitates the detachable installation of the paper feed tray and the telescopic installation of the paper collection tray through the upper and lower workstations with a specific structure. When not in use, the paper feed tray can be removed and the paper collection tray can be retracted to reduce the size of the equipment, making it easier to move the equipment.

[0020] Reference Figures 1-5This invention provides a processing rack for an electronic document conversion device, including a frame 1. The frame 1 has a right-angled triangular structure. The hypotenuse of the frame 1 forms an openable inclined paper feeding channel 4 through a fixed paper feeding base plate 2 and a rotatable paper feeding cover plate 3 at the upper end. The lower end of the paper feeding cover plate 3 is hinged to the lower end of the paper feeding base plate 2 by a shoulder screw, so that the paper feeding cover plate 3 has a structure in which the upper end can rotate and open the inclined paper feeding channel 4. A limiting component 5 is provided in the middle between the paper feeding cover plate 3 and the paper feeding base plate 2 to limit the rotation angle of the paper feeding cover plate 3, so that the paper feeding cover plate 3 can only rotate by a preset angle, for example, limiting the rotation of the paper feeding cover plate 3 to 25°-45° to ensure better stability when opening the inclined paper feeding channel 4. A positioning guide pin 6 and a positioning guide pin hole 7 are provided between the middle of the paper feed cover plate 3 and the middle of the paper feed base plate 2. The positioning guide pin 6 and the positioning guide pin hole 7 can be respectively set on both sides of the paper feed base plate 2 and both sides of the paper feed cover plate 3. The positioning guide pin 6 and the positioning guide pin hole 7 can guide and position the paper feed cover plate 3 when it covers the paper feed base plate 2, so as to ensure that the size of the inclined paper feed channel 4 does not change. In addition, a fastening member 8 is provided between the upper end of the paper feed cover plate 3 and the upper end of the paper feed base plate 2. The fastening member 8 can adopt a conventional structure of L-shaped part, rotating shaft and torsion spring cooperation, which has the function of locking the paper feed base plate 2 and the paper feed cover plate 3, ensuring that the paper feed cover plate 3 will not loosen when the processing rack is running normally. When an abnormality or paper jam occurs, the restriction of the paper feed cover plate 3 can be released by releasing the fastening member 8. At this time, the inclined paper feed channel 4 can be quickly opened for processing by rotating the paper feed cover plate 3.

[0021] In addition, the inclined side of the frame 1 is provided with a paper feeding station 9 for installing the paper feeding device 13, a paper feeding station 10 for installing the paper feeding roller group 14, a scanning station 11 for installing the scanning device 15, and a coding station 12 for installing the coding device 16. The paper feeding stations 10 are arranged at intervals along the inclined direction of the inclined paper feeding channel 4. The paper feeding station 9 is located at the upper part of the inclined paper feeding channel 4, the coding station 12 is located at the lower part of the inclined paper feeding channel 4, and the scanning station 11 is located below the paper feeding station 9 and the coding station 12, respectively. Through the paper feeding station 9, the paper feeding station 10, the scanning station 11, and the coding station 12, the various action mechanisms can be reasonably and centrally arranged on the frame along the inclined paper feeding channel 4, which not only realizes the effective conversion of electronic documents but also reduces the size of the equipment.

[0022] Compared to existing transverse or double-layer turning paper feeding channels, the minimum length of the inclined paper feeding channel 4 in this invention is only 650mm, effectively shortening the paper feeding path length and thus reducing the probability of paper jams and the size of the equipment. The inclined paper feeding channel 4 is essentially composed of two plates inclined and mounted on the frame 1. The inclination angle of the inclined paper feeding channel 4 can be 30-60 degrees, preferably 45 degrees, which has the advantages of simple structure, smooth paper feeding, and less likelihood of paper jams during paper feeding.

[0023] Reference Figure 2 , Figure 4 The limiting component 5 is located in the lower middle part of one side of the paper feed base plate 2, and includes a limiting rod 17 and a limiting pin 18. The limiting pin 18 is fixed to the side wall of the paper feed base plate 2. One end of the limiting rod 17 is hinged to the side wall of the paper feed cover plate 3 and can rotate. The other end is provided with a limiting groove along the length direction, and the limiting pin 18 is located in the limiting groove. The limiting groove includes point A located at the end of the limiting rod 17 and point B located in the middle of the limiting rod 17. When the paper feed cover plate 3 is rotated to open the inclined paper feed channel 4, the limiting pin 18 moves from point B to point A relative to the limiting groove, and reaches the limiting end point when it moves to point A. The paper feed cover plate 3 rotates to the position and cannot continue to rotate.

[0024] Reference Figures 1-4 The frame 1 includes a base 19, on which two right-angled triangular side plates 20 are symmetrically fixed by bolts. The side plates 20 are fixed together by upper and lower support rods. The paper feed bottom plate 2 and the paper feed cover plate 3 are both installed on the hypotenuses of the two side plates 20, so that the frame 1 has a stable and reliable support structure.

[0025] It should be noted that both the paper feed base plate 2 and the paper feed cover plate 3 are rectangular in structure. Multiple buffer pads (not shown in the figure) are glued and fixed between the paper feed base plate 2 and the paper feed cover plate 3. The buffer pads can be made of rubber material. They are used to form an inclined paper feed channel 4 with a stable gap between the paper feed base plate 2 and the paper feed cover plate 3, and to buffer when the paper feed cover plate 3 is rotated to move closer to the paper feed base plate 2, so as to avoid damage to the paper feed cover plate 3 and the paper feed base plate 2 due to hard contact.

[0026] Reference Figures 1-5 The paper feeding station 9 is equipped with corresponding paper feed holes 21 and paper separation holes 22. The paper feed holes 21 are located on the upper part of the paper feed base plate 2 for installing the paper feed rollers in the paper feeding device 13. The paper separation holes 22 are located on the upper part of the paper feed cover plate 3 for installing the separation rollers in the paper feeding device 13. After installation, the paper feed rollers (which perform the paper feed function) and the separation rollers (which perform the separation function) both extend into the inclined paper feeding channel 4. When the paper feeding cover plate 3 is locked by the fastener 8 and the inclined paper feeding channel 4 is in a closed state, the separation rollers correspond to the paper feed rollers. At this time, the paper feed motor and the paper separation motor in the paper feeding device 13 simultaneously drive the paper feed rollers and the separation rollers to rotate, thus feeding the paper documents into the inclined paper feeding channel 4 page by page in an orderly manner.

[0027] Reference Figures 1-5The paper feeding station 10 is provided with several corresponding main paper feeding holes 23 and secondary paper feeding holes 24. The main paper feeding holes 23 are set in groups on the paper feeding base plate 2 for installing the drive wheel group in the paper feeding roller group 14; the secondary paper feeding holes 24 are set in groups on the paper feeding cover plate 3 for installing the driven wheel group in the paper feeding roller group 14. After installation, the conveying parts of the drive wheel group and the conveying parts of the driven wheel group both extend into the inclined paper feeding channel 4. When the paper feeding cover plate 3 is locked by the fastener 8 and the inclined paper feeding channel 4 is in a closed state, the driven wheel group corresponds to the drive wheel group. At this time, the paper feeding motor in the paper feeding roller group 14 simultaneously drives the drive wheel group to rotate, so that the paper in the inclined paper feeding channel 4 is output from top to bottom at an angle.

[0028] Reference Figures 1-5 The scanning station 11 is equipped with scanning windows 25 corresponding to the scanning device 15. These scanning windows 25 are respectively located on the paper feed base plate 2 and the paper feed cover plate 3. After the scanning device 15 is installed on the scanning station 11, it captures images of the passing paper through the scanning windows 25. Specifically, the scanning device 15 installed on the upper first scanning station 11 needs to capture images of both sides of the paper simultaneously to determine if there are blank pages. The scanning device 15 installed on the lower second scanning station 11 only scans pages with images to avoid blank pages in the converted electronic document.

[0029] Reference Figures 1-5 The coding station 12 is equipped with coding windows 26 corresponding to the coding device 16. The coding windows 26 are respectively located on the paper feed base plate 2 and the paper feed cover plate 3. After the coding device 16 is installed on the coding station 12, it encodes the passing paper through the coding windows 26. Based on the scanning structure of the scanning device 15 located at the first scanning station 11 above, the coding device 16 only codes pages with content.

[0030] Reference Figures 1-5 The upper end of the inclined paper feeding channel 4 is provided with an upper station 27 for installing the paper feed tray 29. The upper station 27 can be a bent part of the upper end of the paper feeding base plate 2. The upper station 27 has an insertion hole for inserting the paper feed tray 29, which allows the paper feed tray 29 to form a detachable structure on the processing frame for easy assembly and disassembly. The lower end of the inclined paper feeding channel 4 is provided with a lower station 28 for installing the paper receiving tray 30 through the frame 1. The lower station 28 is provided with a sliding groove for sliding the paper receiving tray 30 on the lower station 28, which allows the paper receiving tray 30 to form a pull-out structure on the processing frame for easy retraction.

[0031] The working principle of this invention, after assembling the paper feeding device 13, the paper feed roller group 14, the scanning device 15, the coding device 16, etc. on the processing frame, is as follows: First, the paper feed device 13, installed at the paper feed station 9, feeds the paper document page by page into the inclined paper feed channel 4. The paper feed roller assembly 14, installed at the paper feed station 10, drives the paper to move downwards along the inclined paper feed channel 4. During the paper movement, the scanning device 15, installed at the upper scanning station 11, captures and stores images of both sides of the paper to determine if there is content on either side. Next, the coding device 16, installed at the coding station 12, codes the pages with content on the paper. After coding, the scanning device 15, installed at the lower scanning station 11, captures and stores images of the pages with content on the paper. Finally, the paper collection tray 30 at the lower station 28 collects the converted paper in an orderly manner. Once the paper document is processed, the corresponding converted electronic document is obtained.

[0032] During the above process, when a paper jam occurs, the fastener 8 is released, and the inclined paper feed channel 4 can be opened by rotating the paper feed cover 3. Since the inclined paper feed channel 4 is fully opened, the inclined paper feed channel 4 and the jammed paper are fully exposed, and the paper can be easily removed for processing, quickly clearing the paper jam without damaging the paper or causing loss of content on the paper, thus achieving better results.

[0033] The above description is merely a specific embodiment of the present invention. Any feature disclosed in this specification may be replaced by other equivalent features unless otherwise specified. All features or steps in all methods or processes disclosed may be combined in any way, except for mutually exclusive features and / or steps.
