Description

Technical Field

[0001] This utility model relates to the field of Internet smart terminal technology; specifically, this utility model relates to an intelligent accounting invoice recognition device. Background Technology

[0002] The accounting field requires various accounting documents, which need to be scanned and archived via internet-connected smart terminals. These smart terminals are equipped with operating systems to enable scanning and data storage, and there are a wide variety of internet-connected smart terminal accounting document scanning devices on the market.

[0003] For example, CN216057166U discloses an internet-connected smart terminal accounting document scanning device, comprising: a housing, a feeding box fixed to the left side of the housing, a micro motor installed inside the feeding box, a paper pushing mechanism installed at the output end of the micro motor, and a guiding mechanism installed inside the housing; a support mechanism is provided on the lower side of the feeding box; and a scanning mechanism installed inside the housing. The paper pushing mechanism includes an adjusting rod, a connecting block, a transmission mechanism, a connecting frame, a first spring, an adjusting frame, a limiting frame, and a limiting wheel. The adjusting rod is installed at the output end of the micro motor. This internet-connected smart terminal accounting document scanning device can effectively push documents of different sizes, ensuring stable document delivery and accurate paper feeding, avoiding document sticking that could lead to scanning errors, and effectively guiding documents to prevent them from falling, ensuring smooth scanning operations.

[0004] While the aforementioned existing technology can handle the transport of documents of different sizes and specifications, the documents are placed parallel in the loading box, and both the top and bottom of the documents are subjected to pressure, resulting in friction between the documents. When transporting the first document at the top, the friction between the first and second documents may cause the second document to be carried out along with the first document, making it very easy for two or more documents to be transported at the same time, which affects the scanning accuracy.

During the transport process, the topmost document is always adsorbed by the adsorption roller and transported to the top of the guide plate. Documents that are not adsorbed are blocked by the guide plate and cannot enter the scanning component. After the adsorption roller finishes adsorption, it exhausts air, blowing the unadsorbed documents downward into the cavity. This allows for pre-processing of documents before scanning, ensuring that only one document is scanned at a time during scanning. Furthermore, the unadsorbed documents are collected uniformly, increasing work efficiency. Attached Figure Description

Detailed Implementation

[0027] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] like Figures 1 to 10 As shown, a typical embodiment of this utility model provides an intelligent accounting document recognition device, including: a housing 1, a paper tray 2, a scanning component 3, a paper feeding roller 4, an adsorption component 5, and a guide plate 6; the housing 1 includes an inlet 1.1 and an outlet 1.2, and slide rails 1.3 are fixedly installed on both sides of the bottom surface inside the inlet 1.1 of the housing 1; the paper tray 2 includes an upper cavity 2.1 and a lower cavity 2.2, and the paper tray 2 is slidably disposed at the inlet 1.1; the scanning component 3 is disposed at the outlet 1.2; the paper feeding roller 4 is rotatably installed inside the housing 1, and the paper feeding roller 4 is located above the paper tray 2 in the height direction; the adsorption component 5 is located between the paper feeding roller 4 and the scanning component 3, and is located above the paper tray 2 in the height direction; the height of the end of the guide plate 6 facing the paper tray 2 is greater than the height of the end facing the scanning component 3, and the height of the end of the guide plate 6 facing the paper tray 2 is greater than the bottom height of the adsorption component 5, for receiving the documents adsorbed by the adsorption component 5.

[0029] When scanning a ticket, first place the ticket horizontally inside the paper tray 2, start the paper feeding roller 4, so that the ticket at the top of the paper tray 2 is driven by the paper feeding roller 4 and moves towards the discharge port 1.2. When the ticket passes under the adsorption component 5, the ticket is adsorbed by the adsorption component 5 and moves with the adsorption component 5.

[0030] If only the topmost document is being moved by the paper feed roller 4, the adsorption component 5 moves the document over the guide plate 6 toward the paper tray 2. If two or more documents are being moved by the paper feed roller 4, the adsorption component 5 still only adsorbs the topmost document and moves it so that the adsorbed document moves over the guide plate 6 toward the paper tray 2. The remaining documents moved by the paper feed roller 4, not being adsorbed by the adsorption component 5, are subject to gravity, causing the end of the document leaving the paper tray 2 to bend downwards and not be able to move over the guide plate 6 toward the paper tray 2 and enter the lower cavity 2.2. This achieves pre-processing of the documents before scanning, ensuring that only one document is scanned during scanning.

[0031] A spring plate 2.3 is installed inside the upper cavity 2.1 of the paper tray 2. A spring 2.4 is fixedly installed at the bottom end of the spring plate 2.3. The bottom end of the spring 2.4 is fixedly installed on the inner bottom surface of the upper cavity 2.1. A handle 2.5 is fixedly installed at the end of the upper cavity 2.1 away from the discharge port 1.2. A paper receiving port 2.21 is opened at the end of the lower cavity 2.2 near the discharge port 1.2. A paper taking port 2.22 is opened at the end of the lower cavity 2.2 away from the discharge port 1.2. Slider 2.6 is fixedly installed on the outer wall of the bottom ends on both sides of the lower cavity 2.2. The slider 2.6 is slidably installed in the slide rail 1.3.

[0032] When paper tray 2 needs to be replenished, pull handle 2.5 to move paper tray 2 outwards towards feed inlet 1.1. After slider 2.6 disengages from slide rail 1.3, paper tray 2 is completely separated from outer casing 1. First, check if there are any documents in lower cavity 2.2. If there are documents in lower cavity 2.2, remove them through paper retrieval port 2.22. Then, place the prepared documents on the top surface of spring plate 2.3, press spring plate 2.3 to compress spring 2.4. Spring plate 2.3 moves down to allow the documents to be located in upper cavity 2.1. Keeping spring 2.4 compressed, insert slider 2.6 into slide rail 1.3 and push paper tray 2 as a whole into feed inlet 1.1 to complete the replenishment of paper tray 2.

[0033] The guide plate 6 includes an upper arc plate 6.1 and a lower arc plate 6.2. The top end of the lower arc plate 6.2 is fixedly installed on the bottom end of the upper arc plate 6.1. The bottom end of the lower arc plate 6.2 is higher than the top end of the scanning component 3. A guide plate 6.3 is fixedly installed at the connection between the upper arc plate 6.1 and the lower arc plate 6.2. The bottom end of the guide plate 6.3 is lower than the top end of the lower cavity 2.2. The bottom end of the guide plate 6.3 is bent towards the paper receiving port 2.21. Baffles 6.4 are fixedly installed on both sides of the guide plate 6. A locking block 6.5 is fixedly installed on the opposite side of the two baffles 6.4. A vent hole 6.6 is opened on the side of the top of the two baffles 6.4 near the upper arc plate 6.1. The opposite ends of the two vent holes 6.6 are inclined downwards.

[0034] When the paper feed roller 4 moves the ticket to below the adsorption component 5, the adsorption component 5 adsorbs the topmost ticket and passes over the top of the upper arc plate 6.1. When the adsorption component 5 stops adsorbing, the ticket that has passed the top of the upper arc plate 6.1 bends downward under the action of gravity. The paper feed roller 4 continues to move, moving the ticket along the upper arc plate 6.1 to the lower arc plate 6.2. When the paper feed roller 4 has finished conveying a ticket, the ticket on the lower arc plate 6.2 will enter the scanning component 3 along the bending direction of the lower arc plate 6.2.

[0035] If the paper feed roller 4 carries out two or more tickets, the ticket at the top is attracted by the adsorption component 5 and passes over the top of the upper arc plate 6.1. The tickets that are not attracted by the adsorption component 5 are blocked by the upper arc plate 6.1 and cannot move into the scanning component 3. The paper feed roller 4 continues to move, moving the tickets that are not attracted along the bending direction of the guide plate 6.3 and driving them into the lower cavity 2.2.

[0036] The paper tray 2 also includes two sets of latches 2.7. The two sets of latches 2.7 are slidably disposed on the outer walls of the paper tray 2 on both sides near the paper receiving port 2.21. Each set of latches 2.7 has two latches. A spring 2.8 is fixedly installed on the opposite side of the two latches 2.7. The end of the spring 2.8 away from the latch 2.7 is fixedly installed on the paper tray 2. A groove 2.71 is opened on the opposite side of the two latches 2.7. The groove 2.71 is adapted to the locking block 6.5.

[0037] When the paper tray 2 is fed into the feed inlet 1.1, the latch 2.7 contacts the latch block 6.5 and continues to push into the feed inlet 1.1, which compresses the spring 2.8 and allows the latch 2.7 to move. When the groove 2.71 on the latch 2.7 moves onto the latch block 6.5, the spring 2.8 returns to its original position, and the latch 2.7 latches onto the latch block 6.5, so that the paper tray 2 can be stably installed in the feed inlet 1.1 without external interference. When the paper tray 2 is removed, the paper tray 2 is pulled outward, which disengages the latch block 6.5 from the groove 2.71, and the paper tray 2 is pulled out.

[0038] The adsorption assembly 5 includes an adsorption roller 5.1, a transmission structure, and an adsorption structure. The adsorption roller 5.1 includes a first end and a second end. The transmission structure includes a drive motor 5.2 and a belt 5.21. The drive motor 5.2 is fixedly installed inside the housing 1. The output end of the drive motor 5.2 is fixedly installed on the axle of the paper feed roller 4. The end of the paper feed roller 4 near the drive motor 5.2 is provided with a belt 5.21. The other end of the belt 5.21 is rotatably connected to the first end of the adsorption roller 5.1.

[0039] When the drive motor 5.2 is started, the paper feed roller 4 rotates, which drives the belt 5.21 to rotate. The belt 5.21 drives the first end of the adsorption roller 5.1 to rotate, so as to achieve the effect of synchronous rotation of the paper feed roller 4 and the adsorption roller 5.1. This prevents the adsorption roller 5.1 from rotating at different speeds than the paper feed roller 4 during the adsorption process, which could cause the paper to be pulled.

[0040] The adsorption roller 5.1 has multiple cavities inside and two adsorption grooves 5.11 on its upper surface. Each of the two adsorption grooves 5.11 has a through hole 5.12. The through holes 5.12 on the two adsorption grooves 5.11 are staggered along the axial direction of the adsorption roller 5.11 and are connected to the cavities. A grid-like baffle plate 6.4 is fixedly installed inside the two adsorption grooves 5.11. The width of the two adsorption grooves 5.11 is adapted to the width of the document.

[0041] When the adsorption roller 5.1 adsorbs, the gas inside the cavity circulates, allowing external air to enter the cavity through the through holes 5.12. When the groove opening of the adsorption groove 5.11 faces downward, one end of the document below is adsorbed onto the adsorption roller 5.1. The adsorption roller 5.1 rotates, pushing the adsorbed end of the document past the top of the guide plate 6. The staggered through holes 5.12 allow the two adsorption grooves 5.11 to achieve the effect of one drawing in air and the other venting air. The baffle plate 6.4 prevents the adsorption groove 5.11 from adsorbing too much document, which would make it difficult to quickly remove the document from the adsorption groove 5.11 during subsequent venting.

[0042] The adsorption structure includes piston plates 5.3 and moving rods 5.31. The number of piston plates 5.3 matches the number of cavities. The moving rod 5.31 includes a first end and a second end. The moving rod 5.31 passes through multiple piston plates 5.3 and through both ends of the adsorption roller 5.1. The first end of the moving rod 5.31 is slidably mounted inside the first end of the adsorption roller 5.1, and the second end of the moving rod 5.31 is slidably mounted inside the second end of the adsorption roller 5.1. An inclined block 5.32 is fixedly mounted on the outer wall of the second end of the moving rod 5.31, and a push block 5.13 is fixedly mounted on the inner wall of the second end of the adsorption roller 5.1. 5.13 includes an inclined surface and a flat surface. The inclined surface of the push block 5.13 is adapted to the inclined surface of the inclined block 5.32. A limit block 5.34 is fixedly installed at the second end of the moving rod 5.31. A fixed sleeve 5.33 is slidably provided on the outside of the second end of the moving rod 5.31. The fixed sleeve 5.33 is fixedly installed on the inner wall of the outer shell 1. A limit groove 5.35 is opened on the fixed sleeve 5.33. The limit block 5.34 is slidably installed in the limit groove 5.35. A spring 5.36 is fixedly installed at the end of the inclined block 5.32 away from the push block 5.13. The spring 5.36 is fixedly installed on the inner wall of the outer shell 1.

[0043] When the adsorption roller 5.1 rotates, the moving rod 5.31 is blocked by the limiting groove 5.35 and will not rotate with the adsorption roller 5.1. When the inclined surface of the push block 5.13 moves to contact the inclined surface of the inclined block 5.32, the push block 5.13 continues to rotate, moving the inclined block 5.32 axially toward the moving rod 5.31, and causing the moving rod 5.31 as a whole to move toward the second end of the adsorption roller 5.1, compressing the spring 3 5.36. When the moving rod 5.31 moves, it causes the piston plate 5.3 to move, thereby causing the air inside the cavity to circulate and adsorb the document into the adsorption groove 5.11, while the other adsorption groove 5.1... 1. Exhaust gas is released through the through hole 5.12. Push block 5.13 continues to move, allowing the flat surface on push block 5.13 to contact inclined block 5.32. This keeps the adsorption groove 5.11 in an adsorption state, transporting the document to a height above guide plate 6. When the flat surface of push block 5.13 passes inclined block 5.32, spring 3 5.36 resets, pushing inclined block 5.32 to move towards the first end of adsorption roller 5.1. Inclined block 5.32 drives moving rod 5.31 to move, which in turn drives piston plate 5.3 to move. As piston plate 5.3 moves, it releases the previously extracted gas, allowing the document to fall from adsorption groove 5.11 and rest on guide plate 6.

[0044] The top of the adsorption roller 5.1 is provided with a wind shield 5.4, which is fixedly installed on the inner wall of the outer shell 1. Paper-stopping rings 5.41 are provided on both sides of the wind shield 5.4. The distance between the two paper-stopping rings 5.41 is adapted to the width of the document. Both ends of the wind shield 5.4 are in contact with the outer surface of the adsorption roller 5.1. Air inlet pipes 5.42 are fixedly installed on both sides of the wind shield 5.4. The bottom end of the air inlet pipes 5.42 is connected to the vent.

[0045] When the adsorption roller 5.1 rotates, the paper stop ring 5.41 limits both ends of the document to prevent it from shifting during rotation. When the adsorption groove 5.11 is inside the wind shield 5.4, the exhaust gas will be discharged into the wind shield 5.4 and then enter the vent through the air duct 5.42. When two or more documents are carried out by the paper feed roller 4, the uppermost document is adsorbed by the adsorption roller 5.1 and transported to the top of the guide plate 6. At the same time, the documents that are not adsorbed will be blown towards the guide plate 6.3 by the gas flowing out of the vent and fall into the lower cavity 2.2, so that the uppermost document and the documents that are not adsorbed can be better separated.

[0046] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
