[0024] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. 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.

[0025] As shown in the figure, a vertical banknote detector includes a body 1, a banknote feeding wheel 11, a banknote feeding belt 12, a banknote rubbing wheel 13, a banknote pressing wheel 21, a banknote blocking wheel 22, a banknote feeding wheel 14, a banknote discharging wheel 15, a banknote feeding counter-rotating wheel 23, a banknote discharging counter-rotating wheel 24, and an inspection mechanism. The banknote discharging end of the body 1 is rotatably equipped with a flipping frame 2. The banknote feeding wheel 11, the banknote feeding belt 12, the banknote rubbing wheel 13, the banknote feeding wheel 14, and the banknote discharging wheel 15 are rotatably mounted on the body 1. The banknote pressing wheel 21, the banknote blocking wheel 22, the banknote feeding counter-rotating wheel 23, the banknote discharging counter-rotating wheel 24, and the inspection mechanism are mounted on the flipping frame 2. The free end of the flipping frame 2 is rotatably equipped with a drive shaft 31. The end of the drive shaft 31 is rotatably equipped with a locking hook 32. The drive shaft 31 is fitted with a torsion spring 33 that acts on the locking hook 32. The body 1 is fixedly equipped with a locking post 34 that is located on the path of the locking hook 32 as it swings with the flipping frame 2 and cooperates with the locking hook 32.

[0026] Specifically, in order to enhance the locking effect between the flipping frame 2 and the body 1, two locking hooks 32 and two locking pins 34 are symmetrically arranged. The two locking hooks 32 are integrally connected by a connecting plate 35, and a toggle plate 36 is fixedly connected to the connecting plate 35.

[0027] Specifically, in order to facilitate the assembly and disassembly of the tilting frame 2, an elastic plate 25 is formed on each side of the end of the tilting frame 2. A cylindrical locking post 26 is formed on the elastic plate 25. The body 1 is provided with a locking hole 16 that matches the locking post 26. The locking post 26 is inserted into the locking hole 16 to realize the rotational connection between the swing frame and the body 1.

[0028] Specifically, in order to enhance the stability of the tilting frame 2 after it falls, two limiting steps 17 are formed on the body 1, which are located on both sides of the tilting frame 2 respectively. The locking pin 34 and the snap-fit ​​hole 16 are provided on the side wall of the limiting step 17.

[0029] In the above structure, the tilting frame 2 is rotatably connected to the machine body 1 through the engagement of the locking pin 26 and the locking hole 16, allowing the tilting frame 2 to swing on the machine body 1 when unrestrained. The rotatable connection between the tilting frame 2 and the machine body 1 via the locking pin 26 and the locking hole 16 facilitates the assembly and disassembly of the tilting frame 2, making it easy to assemble and remove for maintenance when necessary. During the process of tilting the frame 2 downwards and placing it on the limiting step 17... The lower end of the locking hook 32 abuts against the locking pin 34, causing the locking hook 32 to swing away from the locking pin 34 under the pushing action of the locking pin 34 and torsion spring 33. When the flipping frame 2 is placed on the limiting step 17, the locking hook 32 is locked onto the locking pin 34 under the restoring force of the torsion spring 33, thus locking the flipping frame 2 and the machine body 1. At this time, the pressing wheel 21 and the blocking wheel 22 are aligned with the banknote feeding belt 12, the banknote feeding pair wheel 23 is aligned with the banknote feeding wheel 14, and the banknote dispensing pair wheel 24 is aligned with the banknote dispensing wheel 15. In conjunction with the support provided by the limiting step 17 to the flipping frame 2, the stability of the flipping frame 2 when locked to the machine body 1 after it falls is ensured, thereby ensuring the stability of the above-mentioned aligned and coordinated components. This allows banknotes to pass steadily one by one through the banknote passage formed between the flipping frame 2 and the machine body 1 and be inspected by the inspection mechanism on the flipping frame 2, realizing the banknote verification function. The two symmetrically arranged locking hooks 32 and locking pins 34 cooperate to strengthen the locking strength between the flipping frame 2 and the machine body 1, ensuring the stability of the flipping frame 2. The two locking hooks 32 are integrally connected by the connecting plate 35, ensuring the synchronicity of the movement of the two locking hooks 32, thereby ensuring the smoothness of locking or unlocking operations. When it is necessary to flip the flipping frame 2 to clean and maintain the inspection mechanism set on it, the connecting plate 35 is swung by the actuating plate 36, causing the locking hooks 32 to swing away from the locking pins 34, so that the locking hooks 32 and locking pins 34 are disengaged. At this time, the flipping frame 2 can be flipped up. Figure 4 The location shown opens the banknote feeding channel, exposing the inspection mechanism, which facilitates cleaning and maintenance of both the inspection mechanism and the banknote feeding channel, thereby ensuring the accuracy of banknote verification and facilitating the use of this type of vertical banknote verification machine.

[0030] Furthermore, based on the above structure, a support frame 41 is fixedly installed inside the swing frame. A support rod 42 is fixedly connected to the support frame 41, located behind the mounting shaft of the banknote feeding wheel 23. A wheel frame 43, located above the mounting shaft of the banknote feeding wheel 23, is swayingly mounted on the support rod 42. The pressing wheel 21 and the blocking wheel 22 are rotatably mounted on the free end of the wheel frame 43. A first spring 44 is installed inside the flipping frame 2, located between the wheel frame 43 and the mounting shaft of the banknote feeding wheel 23. An adjusting bolt 45, with its end pointing downwards and penetrating into the support frame 41 to abut against the wheel frame 43, is screwed onto the support frame 41. A spring 44 applies a downward elastic force to the mounting shaft of the banknote feeding roller 23, keeping the banknote feeding roller 23 in cooperation with the banknote feeding roller 14. At the same time, it applies an upward elastic force to the roller frame 43, causing the free end of the roller frame 43 to tend to swing upward. The adjusting bolt 45 abuts against the roller frame 43 to limit the upward swing angle of the roller frame 43. This allows the angle of the roller frame 43 on the support rod 42 to be adjusted by adjusting the longitudinal position of the adjusting bolt 45. This, in turn, adjusts the fit clearance between the pressing roller 21 and the blocking roller 22 and the banknote feeding belt 12, making the clearance adaptable to banknotes of different thicknesses, thus ensuring the applicability of the banknote detector when inspecting different banknotes.

[0031] Furthermore, based on the above structure, the adjusting bolt 45 is inverted T-shaped and a second spring 46 is sleeved on the adjusting bolt 45 between the large end of the adjusting bolt 45 and the support frame 41. The two ends of the second spring 46 are respectively pressed against the support frame 41 and the adjusting bolt 45 to generate friction, thereby applying damping to the rotation of the adjusting bolt 45 relative to the support frame 41, ensuring the stability of the adjusting bolt 45 after it is adjusted to the correct position, and thus ensuring the stability of the banknote detection wheel and the banknote blocking wheel 22 when they cooperate with the banknote feeding belt 12.

[0032] Furthermore, based on the above structure, the inspection mechanism includes infrared emitting tubes 51, ultraviolet sensors 52, and magnetic sensors 53 arranged sequentially along the banknote feeding direction. A plurality of infrared emitting tubes 51 are arrayed on the flipping frame 2 in a direction perpendicular to the banknote feeding direction. The machine body 1 is equipped with a plurality of infrared receiving tubes 54 corresponding one-to-one with the infrared emitting tubes 51. The infrared emitting tubes 51 and infrared receiving tubes 54 arrayed along the banknote feeding direction can cover the banknote in the width direction, allowing the infrared light emitted by the infrared emitting tubes 51 to fully cover the banknote. When the banknote passes between the infrared emitting tubes 51 and the infrared receiving tubes 54, the infrared light emitted by the infrared emitting tubes 51 penetrates the banknote and is then received by the infrared receiving tubes 54. Infrared receiver 54 receives the remaining light signal. Based on the differences in paper density, limiting structure, and ink thickness of the banknote, the intensity of the light signal received by infrared receiver 54 at different positions varies, generating the original signal. The original signal is processed by the logic chip and then the main control chip generates a fuzzy feature map of the banknote to achieve fuzzy imaging of the banknote. The fuzzy feature map is matched with the pre-stored banknote feature database to achieve counterfeit detection. This imaging method has strong anti-interference ability, lower cost, and can detect internal structures of the banknote such as security threads. The ultraviolet sensor 52 and the magnetic sensor 53 perform fluorescence detection and magnetic detection of the banknote, respectively. Together with the infrared emitter 51 and the infrared receiver 54, they ensure the accuracy of banknote inspection.

[0033] Furthermore, based on the above structure, the banknote feeding end of the machine body 1 is rotatably connected to a banknote support plate 6. The banknote support plate 6 is provided with a first width limiting plate 61 and a second width limiting plate 62. When the banknote support plate 6 is flipped outward, its inner side connects with the banknote feeding channel of the machine body 1, thereby extending the length of the banknote feeding channel. This allows banknotes of different lengths to be placed more stably in the banknote feeding channel of the machine body 1 for subsequent inspection. The first width limiting plate 61 and the second width limiting plate 62 are located on both sides of the banknote width direction when the banknote is placed on the banknote support plate 6, which plays a positioning role for the banknote and ensures the stability of the banknote during feeding. When the banknote support plate 6 is flipped inward, it can be stored in the banknote feeding channel of the machine body 1, improving the portability of the banknote detector.

[0034] Furthermore, based on the above structure, the first width limiting plate 61 is fixedly connected to the banknote support plate 6, the banknote support plate 6 is provided with a dovetail groove 63, and the lower end of the second width limiting plate 62 is formed with a sliding block 64 that matches the dovetail groove 63 and is inserted into the dovetail groove 63, so as to realize the sliding connection between the second width limiting plate 62 and the banknote support plate 6. The sliding of the sliding block 64 in the sliding groove 63 realizes the sliding of the second width limiting plate 62 on the banknote support plate 6, so as to adjust the distance between the first width limiting plate 61 and the second width limiting plate 62 to adapt to banknotes of different widths.

[0035] Furthermore, based on the above structure, the banknote dispensing end of the machine body 1 is rotatably connected to a banknote receiving cover plate 7, and the flipping frame 2 is rotatably connected to a banknote pressing rod 8 whose end extends into the banknote receiving cover plate 7. When the banknote receiving cover plate 7 flips outward, it is located on the banknote dispensing end side of the machine body 1. After the banknotes that have been inspected leave the banknote dispensing end of the frame 1, they fall into the banknote receiving cover plate 7, which facilitates the collection of the inspected banknotes. The banknote pressing rod 8 is located above the banknotes during the process of the banknotes falling into the banknote receiving cover plate 7, which plays a limiting role in preventing the banknotes from flying up and ensuring that they fall stably into the banknote receiving cover plate 7. When the banknote pressing rod 8 flips inward, it can be placed on the upper end of the flipping frame 2. When the banknote receiving cover plate 7 flips inward, it can cover the upper end of the machine body 1, which improves the portability of the banknote detector.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
