Description

Technical Field

[0001] The utility model relates to the technical field of bill recognition, and specifically relates to a bill recognition device. Background Art

[0002] Bills include various securities and vouchers, such as bills in the narrow sense like stocks, corporate bonds, invoices, bills of lading, etc. Bills need to be entered into a computer for preservation and record-keeping so that they can be retrieved in time when needed. When entering bills into a computer, a bill recognition device is required. Common bill recognition devices usually use a scanning gun fixedly installed on a bracket to scan and recognize, and then enter the information on the bill into the computer. However, the position and angle of the scanning gun cannot be adjusted, resulting in easy errors and distortions during recognition and entry, and unable to meet the working requirements of the bill recognition device.

[0003] The utility model with the publication number CN 216490664 U discloses a bill recognition device. A support rod is fixedly installed on the left side of the top of the base, and the inside of the support rod is a hollow structure. An adjusting disc is installed at the top of the support rod. A gear disc is installed inside the adjusting disc. A clamping groove is opened at the lower part of the left outer wall of the adjusting disc. A plug rod is inserted into the clamping groove, and the other end of the plug rod is inserted between the tooth blocks of the gear disc. Compression springs are fixedly connected to the middle positions on both sides of the rod body of the plug rod, and the other ends of the compression springs are fixedly connected to pressing plates. For this anti-seepage exterior wall thermal insulation and decoration finished board, through the added height adjusting device, the motor can drive the rotation of the lead screw, so that the lead screw drives the up and down movement of the connecting plate, and then the recognition placing plate moves up and down, which facilitates adjusting the distance between the bill and the scanning gun and improves the accuracy of scanning and recognition.

[0004] The above device adjusts the distance between the bill and the scanning gun by adjusting the up and down movement of the connecting plate to improve the recognition accuracy of the scanning gun. This method could indeed improve the scanning accuracy before. After all, the clarity of the previous scanning cameras was not high, and they had to be placed closer to scan clearly. However, with the development of current technology, existing scanning devices have high scanning clarity and a large scanning range, and there is no need to adjust the distance between the scanning device and the bill. The current problem is that some bills will wrinkle when scanned on the placing table, and the paper surface data on them is easily affected by the wrinkles, reducing the scanning efficiency and accuracy. At the same time, the above scanning gun is screwed onto the threaded rod, and the scanning gun is adjusted by driving the threaded rod. Therefore, when the scanning gun needs to be maintained and disassembled, the threaded rod needs to be disassembled first, and then the scanning gun is unscrewed from the threaded rod. This method is time-consuming and laborious and also reduces the working efficiency of the device. Summary of the Utility Model

[0034] In use, first place the bill on the placement table 3, then pull up the two pressure rollers 41 upward so that the torsion spring 44 is stressed. Then move the bill under the pressure rollers 41, and then release the pressure rollers 41. Under the action of the torsion spring 44, the pressure rollers 41 press the bill tightly on the placement table 3. Then pull the pull head 463 outward. The pull head 463 drives the movable rod 462 to move, separating the tooth block 464 from the tooth groove 22. Then move the movable block 43. The movable block 43 drives the pressure rollers 41 to roll on the bill through the connecting rod 42, so that the pressure rollers 41 smooth out the wrinkles of the bill until the pressure rollers 41 move to the end of the bill. At this time, release the pull head 463, and the movable rod 462 resets under the action of the spring 465. At this time, the tooth block 464 meshes with the tooth groove 22, limiting the movable block 43, and further limiting the pressure rollers 41, so that the two pressure rollers 41 cooperate to flatten and limit the bill, facilitating the scanning and identification by the scanning lens 62. When maintenance and repair of the scanning lens 62 are required, move the limiting piece 73 at this time until the limiting piece 73 separates from the extension plate 71. At this time, the limit of the protective cover 7 can be released. After removing the protective cover 7, start the motor 65. The motor 65 drives the lead screw 66 to rotate, and the lead screw 66 drives the two clamping plates 63 to move in opposite directions, releasing the limit of the scanning lens 62. At this time, the scanning lens 62 can be disassembled, replaced and repaired, improving the working efficiency of the device.
