Description

Technical Field

[0001] This utility model relates to the technical field of sheet media processing devices, and in particular to a sheet media conveying mechanism, channel device and banknote processing equipment. Background Technology

[0002] Traditional banknote processing devices include multiple banknote boxes and a conveying mechanism. The banknote boxes are arranged sequentially along a direction. The conveying mechanism includes a conveying channel, a conveying assembly, and a motor arranged along the direction. The motor is driven by the conveying assembly, which drives the banknotes to move within the conveying channel. Each banknote box is connected to the conveying channel, so that the banknotes in each box are conveyed to the banknote outlet by the conveying assembly. Because the length of the conveying mechanism is fixed, this type of banknote processing device cannot add or remove banknote boxes as needed, thus exhibiting poor scalability.

[0003] To address this, a banknote processing device has been provided, comprising multiple banknote boxes and multiple sub-conveyor mechanisms. The banknote boxes are arranged sequentially along a directional axis, and each sub-conveyor mechanism corresponds to one of the banknote boxes. Each sub-conveyor mechanism includes a sub-conveyor channel, a sub-conveyor assembly, and a motor. The motor is connected to the sub-conveyor assembly, which drives the banknotes to move within the sub-conveyor channel. The multiple sub-conveyor channels are connected end-to-end along the directional axis to form a common conveyor channel. Banknotes from each banknote box can enter the common conveyor channel through their corresponding sub-conveyor channel and be conveyed to the banknote outlet. Because each sub-conveyor mechanism has an independent motor for driving the banknotes within the common conveyor channel, this banknote processing device allows for the addition or removal of banknote boxes as needed. However, this also results in higher equipment costs.

[0004] How to satisfy the scalability of the banknote processing device's cash box without increasing equipment costs has become an urgent problem to be solved. Utility Model Content

[0005] The purpose of this utility model is to provide a sheet-type media conveying mechanism, channel device, and banknote processing equipment, which can meet the scalability of the banknote box of the sheet-type media processing device without increasing the equipment cost, and improve the flexibility and versatility of the sheet-type media processing device.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A sheet-like media conveying mechanism includes a frame and a conveying assembly and a transmission assembly mounted on the frame. Along the conveying direction of the sheet-like media, the frame includes a first end and a second end. The conveying assembly includes a first shaft, a second shaft, a conveyor belt, a first pulley, a second pulley, a first driven wheel, and a second driven wheel. The first shaft is located near the first end of the frame, and the second shaft is located near the second end of the frame. The first pulley is fixedly sleeved on the first shaft, and the second pulley is fixedly sleeved on the second shaft. The conveyor belt is supported by the first pulley and the second pulley. The first driven wheel and the second driven wheel both abut against the conveyor belt and form a conveying channel with it. The transmission assembly includes a first gear, a second gear, and a transition gear. The first gear is fixedly sleeved on the first shaft, and the second gear is fixedly sleeved on the second shaft. The transition gear is rotatably mounted on the frame via a support shaft. The transition gear meshes with the second gear, and one of the transition gear and the first gear is used to receive external power, while the other of the transition gear and the first gear is used to output power to the outside.

[0008] As an optional technical solution, the sheet-like media conveying mechanism further includes a first tensioning assembly, which includes a swing frame and an elastic element. The first end of the swing frame is pivotally connected to the frame, and the second end of the swing frame is sleeved on one end of the second shaft along the axial direction. The elastic element is connected between the swing frame and the frame, and the elastic element is used to ensure that the swing frame always has the tendency to drive the second shaft to rotate in the direction of tensioning the conveyor belt. The rotation axis of the swing frame is coaxial with the axis of the support shaft.

[0009] As an optional technical solution, the first tensioning component further includes a limiting member, which is fixedly connected to the frame and is used to limit the extreme position of the swing frame driving the second shaft to rotate.

[0010] As an optional technical solution, along the conveying direction of the sheet-like medium, the first pulley, the first driven pulley, the second driven pulley, and the second pulley are arranged in sequence. The first driven pulley is opposite to the first pulley, the second driven pulley is opposite to the second pulley, and both the first driven pulley and the second driven pulley are in contact with the first surface of the conveyor belt, while both the first pulley and the second pulley are in contact with the second surface of the conveyor belt.

[0011] As an optional technical solution, the frame includes a movable frame and a fixed frame. The second shaft and the conveyor belt are disposed on the movable frame, and the first driven wheel and the second driven wheel are disposed on the fixed frame. The movable frame is rotatably connected to the fixed frame through the first shaft, so that the movable frame has a closed position and an open position relative to the fixed frame. When the movable frame is in the closed position, the conveyor belt simultaneously abuts and cooperates with the first driven wheel and the second driven wheel to jointly form the conveying channel. When the movable frame is in the open position, the conveyor belt simultaneously separates from the first driven wheel and the second driven wheel to open the conveying channel.

[0012] As an optional technical solution, the sheet-like media conveying mechanism further includes a banknote-digging component and a fixed channel. Both the banknote-digging component and the fixed channel are disposed on the fixed frame. When the movable frame is in the closed position, the first end of the fixed channel is connected to the conveying channel. The banknote-digging component includes a banknote-kicking roller, a banknote-splitting roller, a banknote-blocking roller, and a banknote-digging motor. The banknote-kicking roller and the banknote-splitting roller are both drively connected to the banknote-digging motor. The banknote-blocking roller and the banknote-splitting roller are disposed opposite to each other. The banknote-kicking roller is used to drive the sheet-like media to move towards the banknote-splitting roller. The banknote-splitting roller is used to drive the sheet-like media to move towards the second end of the fixed channel. The banknote-blocking roller is used to prevent overlapping sheet-like media from entering the fixed channel.

[0013] As an optional technical solution, the sheet-like media conveying mechanism further includes a locking assembly and a second tensioning assembly. The locking assembly includes a locking shaft, a locking hook, and a locking elastic element. One of the locking shaft and the locking hook is disposed on the movable frame, and the other is disposed on the fixed frame. The locking elastic element is connected to the locking shaft, and the elastic force of the locking elastic element enables the locking shaft to always have a tendency to engage with the locking hook. The second tensioning assembly includes a tensioning frame, a tensioning wheel, and a tensioning elastic element. The tensioning frame is rotatably sleeved on the locking shaft, and the tensioning wheel is rotatably mounted on the tensioning frame. When the tensioning frame rotates around the locking shaft, the tensioning wheel can abut or separate from the conveyor belt. The tensioning elastic element is connected between the tensioning frame and the movable frame, and the elastic force of the tensioning elastic element enables the tensioning frame to always have a tendency to rotate around the locking shaft to tension the conveyor belt with the tensioning wheel.

[0014] This utility model also adopts the following technical solution:

[0015] A channel device includes a plurality of the aforementioned sheet-like media conveying mechanisms, which are arranged sequentially along the conveying direction of the sheet-like media. The multiple conveying channels of the multiple sheet-like media conveying mechanisms are connected end to end to form a common conveying channel. In two adjacent sheet-like media conveying mechanisms, the transition gear of the upstream sheet-like media conveying mechanism meshes with the first gear of the downstream sheet-like media conveying mechanism.

[0016] As an optional technical solution, each of the transmission components of the plurality of sheet-like media conveying mechanisms includes a first limiting post fixedly connected to the first gear on the same axis and a transition limiting post fixedly connected to the transition gear on the same axis. In two adjacent sheet-like media conveying mechanisms, the transition limiting post of the upstream sheet-like media conveying mechanism radially abuts against the first limiting post of the downstream sheet-like media conveying mechanism to limit the radial meshing depth between the transition gear and the first gear.

[0017] This utility model also adopts the following technical solution:

[0018] A banknote processing device includes a banknote outlet, a conveying motor, N banknote boxes, and N sheet-like media conveying mechanisms. The N sheet-like media conveying mechanisms are arranged sequentially along the banknote conveying direction. The N conveying channels of the N sheet-like media conveying mechanisms are connected end-to-end to form a common conveying channel communicating with the banknote outlet. The N banknote boxes are arranged one-to-one with the N sheet-like media conveying mechanisms. Each sheet-like media conveying mechanism is used to convey the banknotes of the corresponding banknote box to the banknote outlet through the common conveying channel. In an adjacent pair of sheet-like media conveying mechanisms, the transition gear of the upstream sheet-like media conveying mechanism meshes with the first gear of the downstream sheet-like media conveying mechanism. Along the banknote conveying direction, the transition gear of the Nth sheet-like media conveying mechanism or the first gear of the first sheet-like media conveying mechanism is connected to the conveying motor.

[0019] The beneficial effects of this utility model are:

[0020] This utility model discloses a sheet-like media conveying mechanism, which includes a frame and a conveying assembly and a transmission assembly mounted on the frame. Along the conveying direction of the sheet-like media, the frame includes a first end and a second end. The conveying assembly includes a first shaft, a second shaft, a conveyor belt, a first pulley, a second pulley, a first driven wheel, and a second driven wheel. The first shaft is located near the first end of the frame, and the second shaft is located near the second end of the frame. The first pulley is fixedly sleeved on the first shaft, and the second pulley is fixedly sleeved on the second shaft. The conveyor belt is supported by the first pulley and the second pulley. The first driven wheel and the second driven wheel both abut against the conveyor belt and form a conveying channel with the conveyor belt. The transmission assembly includes a first gear, a second gear, and a transition gear. The first gear is fixedly sleeved on the first shaft, and the second gear is fixedly sleeved on the second shaft. The transition gear is rotatably mounted on the frame through a support shaft and meshes with the second gear. One of the transition gear and the first gear is used to receive external power, and the other of the transition gear and the first gear is used to output power to the outside. This sheet-type media conveying mechanism allows multiple identical sheet-type media conveying mechanisms to be connected according to actual needs. During connection, power transmission is achieved simply by meshing the first gear or transition gear of the original sheet-type media conveying mechanism (used for power transmission) with the first gear or transition gear of the newly added sheet-type media conveying mechanism (used for power reception). No additional power mechanism is required, resulting in strong scalability and no increase in equipment cost. Furthermore, the sheet-type media conveying mechanism provided by this invention does not require an additional transmission structure between the transition gear or first gear used for receiving external power and the transition gear or first gear used for outputting external power, further reducing the cost of this sheet-type media conveying mechanism.

[0021] This utility model also discloses a channel device, which includes multiple sheet-like media conveying mechanisms as described above. These mechanisms are arranged sequentially along the conveying direction of the sheet-like media, and their conveying channels are connected end-to-end to form a common conveying channel. In two adjacent sheet-like media conveying mechanisms, the transition gear of the upstream mechanism meshes with the first gear of the downstream mechanism. This channel device, by employing the aforementioned sheet-like media conveying mechanisms, allows multiple conveying mechanisms to operate simultaneously with a single power source, reducing the number of power sources required and thus lowering costs. Furthermore, the number of conveying mechanisms can be customized according to actual usage, providing good scalability.

[0022] This utility model also discloses a banknote processing device, which includes a banknote outlet, a conveying motor, N banknote boxes, and N sheet-like media conveying mechanisms. The N sheet-like media conveying mechanisms are arranged sequentially along the banknote conveying direction, and the N conveying channels of the N sheet-like media conveying mechanisms are connected end to end to form a common conveying channel communicating with the banknote outlet. The N banknote boxes are arranged one-to-one with the N sheet-like media conveying mechanisms, and each sheet-like media conveying mechanism is used to convey the banknotes of the corresponding banknote box to the banknote outlet through the common conveying channel. Among the two adjacent sheet-like media conveying mechanisms, the transition gear of the upstream sheet-like media conveying mechanism meshes with the first gear of the downstream sheet-like media conveying mechanism, and along the banknote conveying direction, the transition gear of the Nth sheet-like media conveying mechanism or the first gear of the first sheet-like media conveying mechanism is connected to the conveying motor for transmission. This banknote processing equipment, by incorporating the aforementioned sheet-type media conveying mechanism, can utilize a single conveying motor to drive N sheet-type media conveying mechanisms, thereby reducing equipment costs and improving economic efficiency. Furthermore, the number of sheet-type media conveying mechanisms can be specifically configured according to actual usage, thus exhibiting good scalability. Attached Figure Description

[0042] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0044] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0045] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0046] like Figures 1 to 9 As shown, this embodiment provides a sheet-like media conveying mechanism. The mechanism includes a frame 10 and a conveying assembly 20 and a transmission assembly 30 mounted on the frame 10. Along the conveying direction of the sheet-like media, the frame 10 includes a first end 11 and a second end 12. The conveying assembly 20 includes a first shaft 21, a second shaft 22, a conveyor belt 23, a first pulley 24, a second pulley 25, a first driven pulley 26, and a second driven pulley 27. The first shaft 21 is positioned near the first end 11 of the frame 10, and the second shaft 22 is positioned near the second end 12 of the frame 10. The first pulley 24 is fixedly sleeved on the first shaft 21, and the second pulley 25 is fixedly sleeved on the second shaft 22. The belt 23 is supported by the first pulley 24 and the second pulley 25. The first driven pulley 26 and the second driven pulley 27 both abut against the conveyor belt 23 and form a conveying channel 28 with the conveyor belt 23. The transmission assembly 30 includes a first gear 31, a second gear 32 and a transition gear 33. The first gear 31 is fixedly sleeved on the first shaft 21, the second gear 32 is fixedly sleeved on the second shaft 22, and the transition gear 33 is rotatably mounted on the frame 10 through the support shaft 34. The transition gear 33 meshes with the second gear 32, and one of the transition gear 33 and the first gear 31 is used to receive external power, and the other of the transition gear 33 and the first gear 31 is used to output power to the outside.

[0047] like Figure 3 and Figure 4As shown, in this embodiment, the transition gear 33 is rotatably mounted on the frame 10 via a support shaft 34. The frame 10 provides stable support for it, thereby ensuring the stability of the transition gear 33 during rotation. The transition gear 33 can be connected to an external power source to receive external power, and it meshes with the second gear 32. The power from the external power source can be transmitted to the second gear 32 through the transition gear 33. The second gear 32 and the second pulley 25 are both fixedly mounted on the second shaft 22, and the first gear 31 and the first pulley 24 are both fixedly mounted on the first shaft 21. The conveyor belt 23 is mounted between the first pulley 24 and the second pulley 25. The transition gear 33 can... The second gear 32 drives the second shaft 22 to rotate, causing the conveyor belt 23, which is wound between the first pulley 24 and the second pulley 25, to move. The first driven pulley 26 abuts the conveyor belt 23 against the first pulley 24, and the second driven pulley 27 abuts the conveyor belt 23 against the second pulley 25. When the conveyor belt 23 moves, it drives the first driven pulley 26 and the second driven pulley 27 to rotate, thereby driving the sheet-like medium to move along the conveying channel 28 to complete the conveying function. At the same time, the conveyor belt 23 drives the first pulley 24 to rotate, and the first pulley 24 drives the first shaft 21 and the first gear 31 fixedly connected to the first shaft 21 to rotate, so that the first gear 31 can output power to the outside. Moreover, the transition gear 33 uses the conveyor belt 23 to transmit power to the first gear 31. That is to say, the conveyor belt 23 is used for both conveying sheet-like media and transmitting power, so that no additional transmission structure is needed between the transition gear 33 and the first gear 31, resulting in a simple structure and low cost.

[0048] Optionally, in another embodiment, the first gear 31 can be connected to an external power source to receive external power, which drives the first gear 31 to rotate. The transition gear 33 meshes with the second gear 32 and can output power to the outside. When multiple sheet media conveying mechanisms are connected, the transition gear 33 can mesh with the first gear 31 of another sheet media conveying mechanism. At the same time, the conveyor belt 23 is used to both convey sheet media and transmit power, thereby ensuring that power is transmitted to another sheet media conveying mechanism. This process is repeated to meet the power requirements of multiple interconnected sheet media conveying mechanisms, which will not be elaborated here.

[0049] like Figure 2As shown, in this embodiment, when multiple sheet-like media conveying mechanisms are connected, the transition gears 33 of all sheet-like media conveying mechanisms are used to receive external power, and the first gear 31 is used to output power to the outside. After the transition gear 33 of the first sheet-like media conveying mechanism receives external power, the first gear 31 of the first sheet-like media conveying mechanism meshes with the transition gear 33 of the second sheet-like media conveying mechanism to transmit power to the second sheet-like media conveying mechanism. This process continues, allowing power to be transmitted sequentially to all sheet-like media conveying mechanisms, enabling multiple sheet-like media conveying mechanisms to operate normally. Thus, only one external power source is needed to output power to several sequentially arranged sheet-like media conveying mechanisms, eliminating the need for additional power mechanisms. This not only provides strong scalability but also does not increase equipment costs.

[0050] Optionally, such as Figure 2 and Figure 3 As shown, each transmission component 30 includes a first limiting post 35 coaxially fixedly connected to the first gear 31 and a transition limiting post 36 coaxially fixedly connected to the transition gear 33. While the transition gear 33 in one sheet-like media conveying mechanism and the first gear 31 in another adjacent sheet-like media conveying mechanism are meshed, the transition limiting post 36 radially abuts against the first limiting post 35 to limit the radial meshing depth between the transition gear 33 and the first gear 31, preventing the transition gear 33 from hitting the first gear 31 when meshing, thereby ensuring the reliability and effectiveness of power transmission.

[0051] like Figure 5 As shown, optionally, in this embodiment, two first pulleys 24 are fixedly sleeved on the first shaft 21 at intervals, and two second pulleys 25 are fixedly sleeved on the second shaft 22 accordingly. The two conveyor belts 23 are supported by two pairs of corresponding first pulleys 24 and second pulleys 25, which improves the conveying stability of sheet-like media.

[0052] Thin sheet media can be paper, banknotes, cards, etc. In this embodiment, banknotes are used as an example of thin sheet media.

[0053] Optionally, such as Figure 5 As shown, the sheet-type media conveying mechanism also includes a first tensioning assembly 40, which includes a swing frame 41 and an elastic element 42. The first end of the swing frame 41 is pivotally connected to the frame 10, and the second end of the swing frame 41 is sleeved on one end of the second shaft 22 along the axial direction. The elastic element 42 is connected between the swing frame 41 and the frame 10, and the elastic element 42 is used to make the swing frame 41 always have the tendency to drive the second shaft 22 to rotate in the direction of tensioning the conveyor belt 23. The rotation axis of the swing frame 41 is coaxial with the axis of the support shaft 34.

[0054] In this embodiment, as Figure 5 As shown, the first tensioning assembly 40 includes two swing frames 41 and two elastic members 42. The first ends of both swing frames 41 are pivotally connected to the frame 10, and the second ends of both swing frames 41 are respectively sleeved on both ends of the second shaft 22. The two elastic members 42 are respectively connected between the two swing frames 41 and the frame 10. The elastic force of the two elastic members 42 is used to ensure that the two swing frames 41 always have a tendency to drive the second shaft 22 to rotate in the direction of tensioning the conveyor belt 23. The rotation centers of both swing frames 41 are coaxially arranged with the support shaft 34. This arrangement allows the conveyor belt 23 to reliably transmit power to the first shaft 21, thereby ensuring that the first shaft 21 transmits power to the next sheet-like media conveying mechanism. Furthermore, in this embodiment, two swing frames 41 and two elastic members 42 are provided, which can improve the tensioning effect of the first tensioning assembly 40 on the conveyor belt 23, thereby ensuring its performance.

[0055] Optionally, in this embodiment, as Figure 3 As shown, the transmission assembly 30 also includes a second limiting post 321 coaxially fixedly connected to the second gear 32. The second limiting post 321 radially abuts against the transition limiting post 36 to limit the radial meshing depth between the transition gear 33 and the second gear 32, preventing the second gear 32 from hitting the transition gear 33 when it is driven by the first tensioning assembly 40 to rotate along the direction of the tensioned conveyor belt 23 with the second shaft 22, thereby ensuring safety performance during use.

[0056] Optionally, in this embodiment, as Figures 3 to 5 As shown, the first end 11 of one of the two swing frames 41 is sleeved on the support shaft 34. The first tensioning assembly 40 and the transmission assembly 30 share a support shaft 34, which reduces costs and simplifies the structure.

[0057] Specifically, in this embodiment, a support shaft 34 and a pivot shaft are coaxially and fixedly mounted on the frame 10. The first end of one of the two swing frames 41 is rotatably sleeved on the support shaft 34, and the first end of the other swing frame 41 is rotatably sleeved on the pivot shaft. The transition gear 33 is sleeved on the support shaft 34, thereby meeting its space requirements.

[0058] Furthermore, such as Figure 5 As shown, the first tensioning assembly 40 also includes a limiting member 43, which is fixedly connected to the frame 10. The limiting member 43 is used to limit the extreme position of the swing frame 41 driving the second shaft 22 to rotate.

[0059] In this embodiment, as Figure 5As shown, two limiting members 43 are provided, both of which are fixedly connected to the frame 10. The two limiting members 43 are correspondingly positioned at both ends of the second shaft 22. The two limiting members 43 are used to limit the extreme positions of the rotation of the second shaft 22 driven by the two swing frames 41. Furthermore, the two limiting members 43 are respectively opposite to the two swing frames 41. By limiting the rotational position of the two swing frames 41, the position of the second shaft 22 is limited, preventing the tension of the second pulley 25 on the conveyor belt 23 from being too low, thereby ensuring the effectiveness of power transmission.

[0060] Optionally, in other embodiments, the first tensioning assembly 40 further includes two bearings, which are respectively embedded in the two swing frames 41 and respectively sleeved on both ends of the second shaft 22. Two limiting members 43 are opposite to the two bearings, thereby limiting the position of the two bearings and thus limiting the position of both ends of the second shaft 22, thereby improving the performance.

[0061] Furthermore, such as Figure 8 As shown, along the conveying direction of the sheet-like medium, the first pulley 24, the first driven pulley 26, the second driven pulley 27, and the second pulley 25 are arranged in sequence. The first driven pulley 26 is arranged opposite to the first pulley 24, and the second driven pulley 27 is arranged opposite to the second pulley 25. Both the first driven pulley 26 and the second driven pulley 27 are in contact with the first surface of the conveyor belt 23, and both the first pulley 24 and the second pulley 25 are in contact with the second surface of the conveyor belt 23.

[0062] In this embodiment, this arrangement ensures that the first pulley 24 and the second pulley 25 are as close as possible to the first end 11 and the second end 12 of the frame 10, respectively, so as to effectively transmit power when multiple sheet-like media conveying mechanisms are arranged in sequence. On the other hand, it ensures that the wrap angle between the conveyor belt 23 and the first pulley 24 and the second pulley 25 is large enough, thereby ensuring that the power of the second shaft 22 can be transmitted to the first shaft 21 through the conveyor belt 23, thus ensuring the effectiveness of power transmission.

[0063] Optionally, in this embodiment, as Figure 8 and Figure 9 As shown, the conveying assembly 20 also includes a third driven wheel 29. The first driven wheel 26, the second driven wheel 27, and the third driven wheel 29 are arranged in parallel and in a triangular pattern. The third driven wheel 29 abuts against and tensions the conveyor belt 23. This arrangement allows the third driven wheel 29 to abut against and tension the conveyor belt 23, further improving the reliability of the conveyor belt 23 in conveying sheet-like media and the reliability of power transmission.

[0064] Furthermore, such as Figures 6 to 9As shown, the frame 10 includes a movable frame 13 and a fixed frame 14. The second shaft 22 and the conveyor belt 23 are disposed on the movable frame 13, and the first driven wheel 26 and the second driven wheel 27 are disposed on the fixed frame 14. The movable frame 13 is rotatably connected to the fixed frame 14 through the first shaft 21, so that the movable frame 13 has a closed position and an open position relative to the fixed frame 14. When the movable frame 13 is in the closed position, the conveyor belt 23 simultaneously abuts and cooperates with the first driven wheel 26 and the second driven wheel 27 to jointly form a conveying channel 28. When the movable frame 13 is in the open position, the conveyor belt 23 simultaneously separates from the first driven wheel 26 and the second driven wheel 27 to open the conveying channel 28.

[0065] In this embodiment, as Figure 8 and Figure 9 As shown, when the movable frame 13 is in the closed position, the conveyor belt 23 simultaneously engages with the first driven wheel 26 and the second driven wheel 27, thereby ensuring that the conveying channel 28 can normally convey sheet-like media. When the movable frame 13 is in the open position, the conveyor belt 23 simultaneously separates from the first driven wheel 26 and the second driven wheel 27, and the conveying channel 28 is open, which facilitates the cleaning of jammed sheet-like media and improves the convenience of use.

[0066] Furthermore, such as Figure 8 and Figure 9 As shown, the sheet-like media conveying mechanism also includes a banknote-digging component and a fixed channel 60. Both the banknote-digging component and the fixed channel 60 are mounted on the fixed frame 14. When the movable frame 13 is in the closed position, the fixed channel 60 is connected to the conveying channel 28. The banknote-digging component includes a banknote-kicking roller 51, a banknote-splitting roller 52, a banknote-blocking roller 53, and a banknote-digging motor. The banknote-kicking roller 51 and the banknote-splitting roller 52 are both connected to the banknote-digging motor. The banknote-blocking roller 53 and the banknote-splitting roller 52 are arranged opposite to each other. The banknote-kicking roller 51 is used to drive the sheet-like media to move towards the banknote-splitting roller 52. The banknote-splitting roller 52 is used to drive the sheet-like media to move towards the fixed channel 60. The banknote-blocking roller 53 is used to prevent overlapping sheet-like media from entering the fixed channel 60.

[0067] In this embodiment, as Figure 8 and Figure 9As shown, the banknote-digging component is used to dig banknotes from the banknote box 400, thereby enabling the banknotes inside the banknote box 400 to be extracted and then conveyed to the conveying channel 28 through the fixed channel 60. Specifically, during the banknote-digging process, the arrangement of the banknote-kicking roller 51, the banknote-splitting roller 52, and the banknote-blocking roller 53 ensures that banknotes are conveyed one after another into the conveying channel 28, ensuring the banknote conveying effect. The structure and working principle of the banknote-digging component are existing technologies and will not be described in detail here. Optionally, in this embodiment, when part of a sheet-like medium is stuck in the fixed channel 60 and another part extends into the conveying channel 28, the movable frame 13 can be rotated to switch it to the open position, which can easily pull out the stuck sheet-like medium, improving the convenience of use and the efficiency of eliminating jamming.

[0068] Preferably, such as Figure 9 As shown, when the movable frame 13 is in the open position, one end of the fixed channel 60 is fully exposed, which makes it easier to pull out the banknotes stuck in the fixed channel 60.

[0069] Furthermore, such as Figures 6 to 9 As shown, the sheet-type media conveying mechanism also includes a locking assembly 70 and a second tensioning assembly 80. The locking assembly 70 includes a locking shaft 71, a locking hook 72, and a locking elastic element 73. One of the locking shaft 71 and the locking hook 72 is disposed on the movable frame 13, and the other of the locking shaft 71 and the locking hook 72 is disposed on the fixed frame 14. The locking elastic element 73 is connected to the locking shaft 71, and the elastic force of the locking elastic element 73 enables the locking shaft 71 to always have a tendency to engage with the locking hook 72. The second tensioning assembly 80... Component 80 includes a tensioning frame 81, a tensioning wheel 82, and a tensioning elastic element 83. The tensioning frame 81 is rotatably sleeved on the locking shaft 71, and the tensioning wheel 82 is rotatably mounted on the tensioning frame 81. When the tensioning frame 81 rotates around the locking shaft 71, the tensioning wheel 82 can abut or separate from the conveyor belt 23. The tensioning elastic element 83 is connected between the tensioning frame 81 and the movable frame 13. The elastic force of the tensioning elastic element 83 makes the tensioning frame 81 always have the tendency to rotate around the locking shaft 71 to make the tensioning wheel 82 tension the movement of the conveyor belt 23.

[0070] In this embodiment, the tensioning frame 81 of the second tensioning assembly 80 is sleeved on the locking shaft 71, which reduces the number of parts, saves installation space, and lowers manufacturing costs.

[0071] Optionally, in this embodiment, as Figure 6 and Figure 7As shown, the fixed frame 14 includes two first side plates 141 arranged at relative intervals, and the movable frame 13 includes two second side plates 131 arranged at relative intervals. The two second side plates 131 are located between the two first side plates 141. Both ends of the first shaft 21 and both ends of the second shaft 22 are inserted into the two second side plates 131. Each of the two first side plates 141 is fixedly connected with a locking hook 72. Each of the two second side plates 131 is provided with a long groove 132. Both ends of the locking shaft 71 are slidably inserted into the long groove 132 on the two second side plates 131. An elastic element 42 is connected between the locking shaft 71 and the movable frame 13. The elastic force of the elastic element 42 makes the locking shaft 71 always have a tendency to slide along the long groove 132 so that both ends of the locking shaft 71 are engaged with the locking hooks 72 on the two first side plates 141, thereby ensuring the tensioning effect of the conveyor belt 23 and thus ensuring the power transmission effect.

[0072] Alternatively, in another embodiment, the tensioning wheel 82 is directly sleeved on the locking shaft 71, and the tensioning wheel 82 abuts against the conveyor belt 23 and tensions the conveyor belt 23, which can further ensure the power transmission effect of the conveyor belt 23 and ensure its performance.

[0073] Optionally, in this embodiment, the locking elastic element 73 is a tension spring, and the tensioning elastic element 83 is a torsion spring.

[0074] This embodiment also provides a channel device, which includes multiple sheet-like media conveying mechanisms as described above. The multiple sheet-like media conveying mechanisms are arranged sequentially along the conveying direction of the sheet-like media. The conveying channels 28 of the multiple sheet-like media conveying mechanisms are connected end to end to form a common conveying channel. In two adjacent sheet-like media conveying mechanisms, the transition gear 33 of the upstream sheet-like media conveying mechanism meshes with the first gear 31 of the downstream sheet-like media conveying mechanism.

[0075] In this embodiment, the number of sheet-like media conveying mechanisms can be increased or decreased according to actual usage needs. When the channel device includes at least two of the sheet-like media conveying mechanisms, the transition gear 33 of the upstream sheet-like media conveying mechanism meshes with the first gear 31 of the downstream sheet-like media conveying mechanism, thereby enabling the entire channel device to operate using a single power source. This reduces the number of power sources required, lowers costs, and improves economic efficiency. At the same time, the number of sheet-like media conveying mechanisms in the channel device can be set as needed, making the channel device highly scalable and improving its flexibility and versatility.

[0076] like Figure 1 and Figure 2As shown, this embodiment also provides a banknote processing device, which includes a banknote outlet, a conveying motor, N banknote boxes 400, and N sheet-like media conveying mechanisms as described above. The N sheet-like media conveying mechanisms are arranged sequentially along the banknote conveying direction, and the conveying channels 28 of the N sheet-like media conveying mechanisms are connected end to end to form a common conveying channel communicating with the banknote outlet. The N banknote boxes 400 are arranged one-to-one with the N sheet-like media conveying mechanisms, and each sheet-like media conveying mechanism is used to convey the banknotes of the corresponding banknote box 400 to the banknote outlet through the common conveying channel. Among the two adjacent sheet-like media conveying mechanisms, the transition gear 33 of the upstream sheet-like media conveying mechanism is meshed with the first gear 31 of the downstream sheet-like media conveying mechanism, and along the banknote conveying direction, the transition gear 33 of the Nth sheet-like media conveying mechanism or the first gear 31 of the first sheet-like media conveying mechanism is connected to the conveying motor for transmission.

[0077] In this embodiment, the N sheet-like media conveying mechanisms of the sheet-like media processing device are arranged sequentially in a vertical or horizontal direction, and the conveying channels 28 of the N conveying mechanisms are connected end to end to form a common channel. The conveying motor is driven by the transition gear 33 of the Nth sheet-like media conveying mechanism, and the power of the conveying motor is transmitted to the Nth sheet-like media conveying mechanism. Since the transition gear 33 of the upstream sheet-like media conveying mechanism meshes with the first gear 31 of the downstream sheet-like media conveying mechanism, the power can be transmitted sequentially in the opposite direction of the banknote conveying direction until it is transmitted to the first sheet-like media conveying mechanism. This sheet-like media processing device can add sheet-like media conveying mechanisms as needed, has strong scalability, and is simple in structure and low in cost.

[0078] Optionally, in another embodiment, the conveying motor is drivenly connected to the first gear 31 of the first sheet-like medium conveying mechanism, and the power of the conveying motor is transmitted to the first sheet-like medium conveying mechanism. Since the transition gear 33 of the upstream sheet-like medium conveying mechanism is meshed with the first gear 31 of the downstream sheet-like medium conveying mechanism, the power can be transmitted sequentially along the banknote conveying direction until it is transmitted to the Nth sheet-like medium conveying mechanism. This will not be elaborated further here.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
