Description

Technical Field

[0001] This utility model relates to the field of financial equipment technology, and in particular to a thin-film media conveying device and a cash processing device. Background Technology

[0002] The cash handling equipment provided by the related technology includes a banknote inlet / outlet, an upper conveyor channel, a lower conveyor channel, a safe, and multiple banknote boxes installed inside the safe. The banknote inlet / outlet is used to receive and / or output banknotes. The upper and lower conveyor channels are both used to transport banknotes. The banknote inlet / outlet, upper conveyor channel, and lower conveyor channel are connected in sequence, and the lower conveyor channel is connected to each banknote box. This allows banknotes in the banknote boxes to enter the banknote inlet / outlet sequentially through the lower and upper conveyor channels, enabling users to retrieve banknotes through the banknote inlet / outlet. When a user forgets to retrieve banknotes from the banknote inlet / outlet or places banknotes in the banknote inlet / outlet, the banknotes from the banknote inlet / outlet sequentially enter the banknote boxes through the upper and lower conveyor channels.

[0003] However, the cash handling equipment in the relevant technology has problems with cash handling during the cash dispensing process (from the lower conveyor channel to the upper conveyor channel) and the cash receiving process (from the upper conveyor channel to the lower conveyor channel). Utility Model Content

[0004] The purpose of this invention is to provide a sheet-like media conveying device and a cash processing equipment to improve the smoothness of banknotes entering and leaving the conveying channel.

[0005] On the one hand, this utility model provides a sheet-like media conveying device, which includes:

[0006] Mounting rack;

[0007] The first pivot shaft is supported by the mounting bracket and can rotate relative to the mounting bracket about its own axis;

[0008] A first channel plate is sleeved with the first pivot shaft, and the first channel plate can rotate relative to the first pivot shaft about the axis of the first pivot shaft;

[0009] The second channel plate is pivotally connected to the mounting frame via a second pivot shaft. The first channel plate and the second channel plate are opposite to each other and spaced apart, forming a conveying channel between them to guide the movement of sheet-like media. The two ends of the conveying channel have a first inlet and a second inlet and a second outlet, respectively.

[0010] The drive mechanism includes a motor and a transmission assembly. The motor is connected to the first pivot shaft and can drive the first pivot shaft to rotate about its own axis. When the motor drives the first pivot shaft to rotate in a first direction, the first pivot shaft drives the first channel plate and the second channel plate to rotate in opposite directions through the transmission assembly, so that one of the first inlet / outlet and the second inlet / outlet forms an opening, and the other of the first inlet / outlet and the second inlet / outlet forms a closing, and the size of the opening is larger than the size of the closing.

[0011] The conveying mechanism includes a conveying wheel, which is fixedly sleeved on the first pivot shaft. When the first pivot shaft rotates around its own axis, the conveying wheel rotates with the first pivot shaft and can drive the sheet-like medium to move in the direction from open to closed.

[0012] As a preferred technical solution for a sheet-type media conveying device, when the motor drives the first pivot shaft to rotate in the first direction, the first pivot shaft is connected to the transmission assembly and drives the first channel plate and the second channel plate to rotate in opposite directions through the transmission assembly, so that the first inlet and outlet form the constriction and the second inlet and outlet form the opening.

[0013] The drive mechanism also includes an elastic element connected to the mounting bracket. When the motor drives the first pivot shaft to rotate in the second direction, the first pivot shaft is disconnected from the transmission assembly. The elastic element drives the first channel plate and the second channel plate to rotate in opposite directions, causing the first inlet and outlet to form the opening and the second inlet and outlet to form the closing. The second direction is opposite to the first direction.

[0014] As a preferred technical solution for a sheet-type media conveying device, the transmission assembly includes a first gear and a one-way bearing. The inner ring of the one-way bearing is fixedly sleeved on the first pivot shaft, and the first gear is fixedly sleeved on the outer ring of the one-way bearing. The first gear is used for transmission connection with the second channel plate. The second channel plate is transmission connected with the first channel plate, and when the second channel plate rotates, it drives the first channel plate to rotate in the opposite direction.

[0015] The one-way bearing is configured such that when the motor drives the first pivot shaft to rotate in the first direction, the inner ring and the outer ring of the one-way bearing are tightly engaged with each other; when the motor drives the first pivot shaft to rotate in the second direction, the inner ring and the outer ring of the one-way bearing slip with each other.

[0016] As a preferred technical solution for the sheet-like media conveying device, the transmission assembly further includes a first toothed portion and a second toothed portion that mesh with each other. The first toothed portion is fixedly connected to the first channel plate and is coaxially arranged with the first pivot shaft. The second toothed portion is fixedly connected to the second channel plate and is coaxially arranged with the second pivot shaft.

[0017] The first gear is used for transmission connection with the second toothed portion.

[0018] As a preferred technical solution for a sheet-type media conveying device, the first inlet and outlet are formed between the first end of the first channel plate and the first end of the second channel plate, and the second inlet and outlet are formed between the second end of the first channel plate and the second end of the second channel plate.

[0019] The sheet-like media conveying device further includes a first limiting part and a second limiting part. The first limiting part is connected to a first end of the first channel plate, and the second limiting part is connected to a first end of the second channel plate. When the opening is formed by the first inlet and outlet and the opening is formed by the second inlet and outlet, the second limiting part abuts against the first limiting part to limit the minimum size of the opening.

[0020] The transmission assembly further includes a torque limiter. When the motor drives the first pivot shaft to rotate in the first direction and the first limiting part and the second limiting part do not abut, the torque limiter causes the first gear to be connected to the second toothed part in a transmission connection. When the motor drives the first pivot shaft to rotate in the first direction and the first limiting part and the second limiting part abut, the torque limiter causes the first gear to be disconnected from the second toothed part in a transmission connection.

[0021] As a preferred technical solution for a sheet-type media conveying device, the torque limiter includes:

[0022] A drive shaft is rotatably mounted on the mounting bracket;

[0023] A torsion spring is sleeved with the drive shaft, and the inner ring of the torsion spring can generate a set damping between the drive shaft and the torsion spring.

[0024] The second gear is connected to the first gear in a transmission manner, and the second gear is sleeved with the torsion spring. The torsion spring has a plug-in part, and the inner ring of the second gear has a slot. The plug-in part is inserted into the slot so that the second gear and the torsion spring are linked together.

[0025] The third gear is fixedly connected to the transmission shaft and meshes with the second toothed portion. When the motor drives the first pivot shaft to rotate in the first direction and the first limiting portion and the second limiting portion do not abut, the rotational resistance of the transmission shaft is less than the set damping, and the torsion spring is connected to the transmission shaft. When the motor drives the first pivot shaft to rotate in the first direction and the first limiting portion and the second limiting portion abut, the rotational resistance of the transmission shaft is greater than the set damping, and the torsion spring and the transmission shaft slip relative to each other.

[0026] In a preferred embodiment of the sheet-type media conveying device, the first channel plate and the second channel plate are drivenly connected, and the elastic element is connected between the first channel plate and the mounting bracket. When the elastic element drives the first channel plate to rotate, the first channel plate drives the second channel plate to rotate synchronously in the opposite direction; or...

[0027] The first channel plate and the second channel plate are connected by a transmission link. The elastic element is connected between the second channel plate and the mounting bracket. When the elastic element drives the second channel plate to rotate, the second channel plate drives the first channel plate to rotate synchronously in the opposite direction; or...

[0028] The elastic element includes a first elastic element and a second elastic element. The first elastic element is connected between the first channel plate and the mounting bracket, and the second elastic element is connected between the second channel plate and the mounting bracket. When the first elastic element drives the first channel plate to rotate, the second elastic element drives the second channel plate to rotate in the opposite direction.

[0029] As a preferred technical solution for a sheet-type media conveying device, the mounting frame includes a first mounting plate and a second mounting plate that are arranged opposite to and spaced apart from each other. The first mounting plate is opposite to the first channel plate, and the second mounting plate is opposite to the second channel plate. The elastic element includes an elastic plate.

[0030] When the first channel plate and the second channel plate are connected in a transmission manner, and the elastic element is connected between the first channel plate and the mounting bracket: the first end of the elastic plate is connected to the first channel plate, and the second end of the elastic plate is suspended and elastically abuts against the first mounting plate.

[0031] As a preferred technical solution for a sheet-type media conveying device, the transmission assembly includes a first transmission structure and a second transmission structure. The first pivot shaft is connected to the second channel plate via the first transmission structure. The second transmission structure includes a first toothed portion and a second toothed portion that mesh with each other. The first toothed portion is fixedly connected to the first channel plate and is coaxially arranged with the first pivot shaft. The second toothed portion is fixedly connected to the second channel plate and is coaxially arranged with the second pivot shaft.

[0032] When the motor drives the first pivot shaft to rotate in the first direction, the first pivot shaft drives the second channel plate to rotate through the first transmission structure, and the second channel plate drives the first channel plate to rotate synchronously in opposite directions through the meshing first toothed portion and the second toothed portion, so that the first inlet and outlet form the constriction and the second inlet and outlet form the opening;

[0033] When the motor drives the first pivot shaft to rotate in the second direction, the first pivot shaft drives the second channel plate to rotate through the first transmission structure, and the second channel plate drives the first channel plate to rotate synchronously in opposite directions through the meshing first toothed portion and the second toothed portion, so that the first inlet and outlet form the opening and the second inlet and outlet form the closing, and the first direction and the second direction are opposite.

[0034] The sheet-type media conveying device provided by this utility model has at least the following beneficial effects:

[0035] The sheet-like media conveying device includes a mounting frame, a first pivot shaft, a first channel plate, a second channel plate, a conveying mechanism, and a driving mechanism. The first pivot shaft is supported by the mounting frame and can rotate relative to the mounting frame about its own axis. The first channel plate is sleeved with the first pivot shaft and can rotate relative to the first pivot shaft about its axis. The second channel plate is pivotally connected to the mounting frame via a second pivot shaft. The first and second channel plates are opposite to each other and spaced apart, forming a conveying channel between them to guide the movement of the sheet-like media. The two ends of the conveying channel have a first inlet and a second inlet, respectively. The driving mechanism includes a motor and a transmission assembly. The first pivot shaft is driven by a motor that can drive the first pivot shaft to rotate around its own axis. When the motor drives the first pivot shaft to rotate in a first direction, the first pivot shaft drives the first channel plate and the second channel plate to rotate in opposite directions through a transmission assembly, so that one of the first inlet and the second inlet and the third inlet and the fourth inlet and the fifth inlet and the sixth inlet and the seventh inlet and the seventh inlet and the eighth inlet and the seventh inlet and the eighth inlet and the seventh inlet and the eighth inlet and the seventh inlet and the eighth inlet and the ninth ... The sheet-like media conveying device provided in this embodiment, when the motor drives the first pivot shaft to rotate in the first direction, the first pivot shaft drives one end of the first channel plate and one end of the second channel plate to rotate in opposite directions and move closer to each other through the transmission assembly, while the other ends of the first channel plate and the other ends of the second channel plate rotate in opposite directions and move away from each other. This causes one of the first inlet and outlet and the second inlet and outlet to expand and form an opening, while the other of the first inlet and outlet and the second inlet and outlet shrinks and forms a closed opening, thereby allowing banknotes to smoothly enter and exit the conveying channel. In addition, when the motor drives the first pivot shaft to rotate, it also drives the conveying wheel to rotate, causing the conveying wheel to drive the sheet-like media to enter the conveying channel through the opening and exit through the closed opening. This reduces the number of motors and lowers the cost, which is beneficial for achieving a compact structure.

[0036] On the other hand, this utility model provides a cash processing device, including an upper device, a lower device, and a sheet-like medium conveying device as described in any of the above-mentioned solutions. The upper device includes a banknote inlet / outlet and an upper conveying channel communicating with the banknote inlet / outlet. The lower device is located below the upper device.

[0062] Please refer to Figure 1 and Figure 2This embodiment provides a cash processing device, which includes an upper device 10, a lower device 20, and a sheet-like medium conveying device 30. The upper device 10 includes a banknote inlet / outlet 101 and an upper conveying channel 102 connected to the banknote inlet / outlet 101. The lower device 20 is located below the upper device 10 and includes a safe 201, multiple banknote boxes 202 disposed in the safe 201, and a lower conveying channel 203 connected to all multiple banknote boxes 202. The sheet-like medium conveying device 30 is embedded in the top wall of the safe 201, and the first inlet / outlet 24 of the sheet-like medium conveying device 30 is connected to the lower conveying channel 203, and the second inlet / outlet 25 of the sheet-like medium conveying device 30 is connected to the upper conveying channel 102. The upper conveying channel 102 and the lower conveying channel 203 are both used to transport banknotes. Banknotes in the banknote inlet / outlet 101 and the banknote box 202 can enter the banknote inlet / outlet 101 in sequence through the lower conveying channel 203, the sheet-like medium conveying device 30 and the upper conveying channel 102, so that users can take out banknotes through the banknote inlet / outlet 101. When users forget to take out banknotes from the banknote inlet / outlet 101 or when users place banknotes in the banknote inlet / outlet 101, the banknotes in the banknote inlet / outlet 101 will enter the banknote box 202 in sequence through the upper conveying channel 102, the sheet-like medium conveying channel 23 and the lower conveying channel 203.

[0063] Optionally, the cash processing equipment also includes a reader 40, which is used to collect information about banknotes passing through the upper conveyor channel 102.

[0064] Please refer to Figures 2 to 4 The sheet-like media conveying device 30 includes a mounting frame 1, a first pivot shaft 51, a first channel plate 21, a second channel plate 22, a conveying mechanism 3, and a driving mechanism 4. The first pivot shaft 51 is supported by the mounting frame 1 and can rotate relative to the mounting frame 1 about its own axis. The first channel plate 21 is sleeved with the first pivot shaft 51 and can rotate relative to the first pivot shaft 51 about its axis. The second channel plate 22 is pivotally connected to the mounting frame 1 via the second pivot shaft 52. The first channel plate 21 and the second channel plate 22 are opposite to each other and spaced apart, forming a conveying channel 23 between them to guide the movement of the sheet-like media. The two ends of the conveying channel 23 have a first inlet / outlet 24 and a second inlet / outlet 25, respectively. The driving mechanism 4 includes a motor (not shown in the figures) and a transmission assembly 41. The motor is connected to the first pivot shaft 51 and can drive the first pivot shaft 51 to rotate about its own axis. When the motor drives the first pivot shaft 51 along a first direction (e.g., ...), the motor can drive the first pivot shaft 51 to rotate about its own axis. Figure 3When the first pivot shaft 51 rotates (in the direction indicated by the middle arrow oa), the first pivot shaft 51 drives the first channel plate 21 and the second channel plate 22 to rotate in opposite directions through the transmission assembly 41, so that one of the first inlet / outlet 24 and the second inlet / outlet 25 forms an opening, and the other of the first inlet / outlet 24 and the second inlet / outlet 25 forms a closing, and the size of the opening is larger than the size of the closing; the conveying mechanism 3 includes a conveying wheel 31, which is fixedly sleeved on the first pivot shaft 51. When the first pivot shaft 51 rotates around its own axis, the conveying wheel 31 rotates with the first pivot shaft 51 and can drive the sheet-like medium to move in the direction from the opening to the closing.

[0065] The sheet-like media conveying device 30 provided in this embodiment, when the motor drives the first pivot shaft 51 to rotate in a first direction, the first pivot shaft 51 drives one end of the first channel plate 21 and one end of the second channel plate 22 to rotate in opposite directions and move closer to each other, while the other ends of the first channel plate 21 and the other ends of the second channel plate 22 rotate in opposite directions and move away from each other. This causes one of the first inlet / outlet 24 and the second inlet / outlet 25 to expand and form an opening, while the other of the first inlet / outlet 24 and the second inlet / outlet 25 to shrink and form a closed opening, thereby allowing banknotes to smoothly enter and exit the conveying channel 23. In addition, when the motor drives the first pivot shaft 51 to rotate, it also drives the conveying wheel 31 to rotate, causing the conveying wheel 31 to drive the sheet-like media into the conveying channel 23 through the opening and out through the closed opening. This reduces the number of motors and lowers the cost, which is beneficial for achieving a compact structure. It should be noted that in other embodiments, the banknotes can also be other sheet-like media such as checks.

[0066] Optionally, the second pivot shaft 52 is supported by a mounting bracket, and the second pivot shaft 52 is integrally formed with the second channel plate 22. In other embodiments, the second pivot shaft 52 is supported by the mounting bracket 1, and the second channel plate 22 is sleeved with the second pivot shaft 52 and can rotate relative to the second pivot shaft 52 about the axis of the second pivot shaft 52.

[0067] Specifically, when banknotes are discharged from the banknote box 202, the first inlet / outlet 24 is opened, and the second inlet / outlet 25 is closed. The open inlet / outlet connects to the lower conveyor channel 203, and the closed inlet / outlet connects to the upper conveyor channel 102. Banknotes in the banknote box 202 can smoothly enter the conveyor channel 23 sequentially through the lower conveyor channel 203 and the open inlet / outlet, and then enter the upper conveyor channel 102 through the closed inlet / outlet. The banknotes are then discharged through the upper conveyor channel 102 to the banknote inlet / outlet 101 for the user to retrieve. If the user forgets to retrieve the banknotes from the banknote inlet / outlet 101, the second inlet / outlet 25 is opened, and the first inlet / outlet... The outlet 24 forms a constriction, connecting with the upper conveyor channel 102 through the open end and with the lower conveyor channel 203 through the constriction. Banknotes entering and exiting the banknote inlet 101 can smoothly enter the conveyor channel 23 through the upper conveyor channel 102 and the open end, and then enter the lower conveyor channel 203 through the constriction. This allows the banknotes to enter the banknote box 202 for recycling through the lower conveyor channel 203. Therefore, the smoothness of banknote movement is improved during the banknote dispensing process from the lower conveyor channel 203 to the upper conveyor channel 102 and the banknote receiving process from the upper conveyor channel 102 to the lower conveyor channel 203.

[0068] Alternatively, please refer to Figures 3 to 5 The conveying mechanism 3 further includes a driven wheel 32 rotatably mounted on the second channel plate 22 and coaxial with the second pivot shaft 52. The driven wheel 32 cooperates with the conveying wheel 31 within the conveying channel 23, and the conveying wheel 31 and the driven wheel 32 are used to jointly clamp and convey banknotes along the conveying channel 23. This arrangement can further improve the smoothness of banknotes entering and exiting the conveying channel 23. Preferably, the conveying mechanism 3 includes a plurality of conveying wheels 31, all of which are fixedly sleeved on the first pivot shaft 51 and are spaced apart along the axial direction of the first pivot shaft 51. The conveying mechanism 3 also includes a plurality of driven wheels 32, all of which are rotatably mounted on the second channel plate 22 and are spaced apart along the axial direction of the second pivot shaft 52. The plurality of driven wheels 32 and the plurality of conveying wheels 31 cooperate one-to-one within the conveying channel 23.

[0069] Alternatively, please refer to Figure 3 and Figure 4 When the motor drives the first pivot shaft 51 to rotate in the first direction, the first pivot shaft 51 is connected to the transmission assembly 41 and drives the first channel plate 21 and the second channel plate 22 to rotate in opposite directions, causing the first inlet / outlet 24 to form a constriction and the second inlet / outlet 25 to form an opening; the drive mechanism 4 also includes an elastic element 43 connected to the mounting bracket 1, when the motor drives the first pivot shaft 51 to rotate in the second direction (e.g., ... Figure 3When rotating in the direction indicated by the middle arrow ob, the first pivot shaft 51 disconnects from the transmission assembly 41. The elastic element 43 drives the first channel plate 21 and the second channel plate 22 to rotate in opposite directions, causing the first inlet / outlet 24 to open and the second inlet / outlet 25 to close. The second direction is opposite to the first direction. This arrangement ensures that when a sheet-like medium needs to move along the direction from the first inlet / outlet 24 to the second inlet / outlet 25, the first pivot shaft 51 disconnects from the transmission assembly 41. When the first pivot shaft 51 rotates, there is no power to drive the first channel plate 21 and the second channel plate 22 to rotate. Under the action of the elastic element 43, the first channel plate 21 and the second channel plate 22 rotate in opposite directions, causing the first inlet / outlet 24 to open and the second inlet / outlet 25 to close. Simultaneously, the conveying wheel 31 rotates with the first pivot shaft 51 and drives the sheet-like medium along the direction from the first inlet / outlet 24 to the second inlet / outlet 25. The movement of outlet 25 reduces the operating load on the motor. When it is necessary to move the sheet-like medium along the direction from the second inlet / outlet 25 to the first inlet / outlet 24, the first pivot shaft 51 is connected to the transmission assembly 41. The first pivot shaft 51 drives the first channel plate 21 and the second channel plate 22 to rotate in opposite directions through the transmission assembly 41, making the second inlet / outlet 25 open and the first inlet / outlet 24 closed. At the same time, the conveying wheel 31 rotates with the first pivot shaft 51 and drives the sheet-like medium to move along the direction from the second inlet / outlet 25 to the first inlet / outlet 24.

[0070] Alternatively, please refer to Figure 3 , Figure 4 , Figure 6 and Figure 7 In this embodiment, the first channel plate 21 and the second channel plate 22 are connected by a transmission mechanism. An elastic element 43 is connected between the first channel plate 21 and the mounting bracket 1. When the elastic element 43 drives the first channel plate 21 to rotate, the first channel plate 21 drives the second channel plate 22 to rotate synchronously in the opposite direction. This configuration, through the transmission connection between the first channel plate 21 and the second channel plate 22, allows only the elastic element 43 to drive the first channel plate 21 to rotate, which in turn drives the second channel plate 22 to rotate synchronously in the opposite direction, saving costs and resulting in a compact structure.

[0071] As an alternative, the first channel plate 21 and the second channel plate 22 are connected by a transmission mechanism. The elastic element 43 is connected between the second channel plate 22 and the mounting bracket 1. When the elastic element 43 drives the second channel plate 22 to rotate, the second channel plate 22 drives the first channel plate 21 to rotate synchronously in the opposite direction. With this configuration, by driving the first channel plate 21 and the second channel plate 22 through a transmission mechanism, it is only necessary for the elastic element 43 to drive the second channel plate 22 to rotate, which can drive the first channel plate 21 to rotate synchronously in the opposite direction. This can also save costs and improve the compactness of the structure.

[0072] As an alternative, the elastic element 43 includes a first elastic element and a second elastic element. The first elastic element is connected between the first channel plate 21 and the mounting bracket 1, and the second elastic element is connected between the second channel plate 22 and the mounting bracket 1. When the first elastic element drives the first channel plate 21 to rotate, the second elastic element drives the second channel plate 22 to rotate in the opposite direction. This configuration allows the first channel plate 21 and the second channel plate 22 to rotate in opposite directions via two elastic elements respectively.

[0073] Alternatively, please continue to refer to Figure 3 , Figure 4 , Figure 6 and Figure 7 In this embodiment, the mounting frame 1 includes a first mounting plate 11 and a second mounting plate 12 that are opposite to and spaced apart. The first mounting plate 11 is opposite to the first channel plate 21, and the second mounting plate 12 is opposite to the second channel plate 22. The elastic element 43 includes an elastic plate 431. The first end of the elastic plate 431 is connected to the first channel plate 21, and the second end of the elastic plate 431 is suspended and elastically abuts against the first mounting plate 11. With this configuration, when the first pivot shaft 51 is connected to the transmission assembly 41, the first pivot shaft 51 drives the first channel plate 21 and the second channel plate 22 to rotate in opposite directions through the transmission assembly 41. At the same time, the first channel plate 21 presses the second end of the elastic plate 431 against the first mounting plate 11, and the elastic plate 431 undergoes elastic deformation. When the first pivot shaft 51 is disconnected from the transmission assembly 41, the elastic plate 431 elastically resets. Under the action of the elastic force of the elastic plate 431, the elastic plate 431 drives the first channel plate 21 to rotate, and then the first channel plate 21 drives the second channel plate 22 to rotate synchronously in opposite directions. In other embodiments, the elastic element 43 may also be configured as a compression spring or a tension spring.

[0074] Alternatively, please refer to Figure 7 In this embodiment, the elastic element 43 further includes a fixing plate 432 and a snap-fit ​​plate 433. The fixing plate 432 is connected to the first channel plate 21 via fasteners 6. The elastic plate 431 is connected to the first end of the fixing plate 432 at an angle, and the snap-fit ​​plate 433 is connected to the second end of the fixing plate 432 at an angle. The snap-fit ​​plate 433 engages with the first channel plate 21. This configuration improves the installation stability of the elastic element 43.

[0075] Alternatively, please refer to Figure 2The mounting bracket 1 also includes a third mounting plate 13 and a fourth mounting plate 14 that are axially opposite to and spaced apart along the first pivot shaft 51. The third mounting plate 13 and the fourth mounting plate 14 are both connected between the first mounting plate 11 and the second mounting plate 12. The two ends of the first pivot shaft 51 are supported by the third mounting plate 13 and the fourth mounting plate 14, respectively. The two ends of the second pivot shaft 52 are supported by the third mounting plate 13 and the fourth mounting plate 14, respectively.

[0076] Alternatively, please refer to 2. Figure 8 and Figure 9 In this embodiment, the transmission assembly 41 includes a first gear 411 and a one-way bearing 412. The inner ring of the one-way bearing 412 is fixedly sleeved on the first pivot shaft 51, and the first gear 411 is fixedly sleeved on the outer ring of the one-way bearing 412. The first gear 411 is used for transmission connection with the second channel plate 22. The one-way bearing 412 is configured such that when the motor drives the first pivot shaft 51 to rotate in a first direction, the inner ring and the outer ring of the one-way bearing 412 are tightly engaged with each other; when the motor drives the first pivot shaft 51 to rotate in a second direction, the inner ring and the outer ring of the one-way bearing 412 slip with each other. With this configuration, when the motor drives the first pivot shaft 51 to rotate in the second direction, the inner and outer rings of the one-way bearing 412 slip against each other, causing the first pivot shaft 51 to disconnect from the first gear 411. The first pivot shaft 51 then lacks the power to drive the first gear 411 to rotate, thus preventing the first channel plate 21 and the second channel plate 22 from rotating. Under the action of the elastic element 43, the first channel plate 21 and the second channel plate 22 rotate in opposite directions, causing the first inlet / outlet 24 to open and the second inlet / outlet 25 to close, allowing the sheet-like medium to travel along the first inlet / outlet 24 to the second inlet / outlet. The first pivot shaft 51 moves in the direction of the first pivot 25. When the motor drives the first pivot shaft 51 to rotate in the first direction, the inner and outer rings of the one-way bearing 412 clamp together. The first pivot shaft 51 is connected to the first gear 411 through the clamping inner and outer rings. The first pivot shaft 51 drives the first gear 411 to rotate. The first gear 411 drives the second channel plate 22 to rotate. The second channel plate 22 drives the first channel plate 21 to rotate in the opposite direction, so that the second inlet and outlet 25 forms an open opening and the first inlet and outlet 24 forms a closed opening, so that the sheet-like medium moves in the direction from the second inlet and outlet 25 to the first inlet and outlet 24.

[0077] Alternatively, please refer to Figures 3 to 6The transmission assembly 41 further includes a first toothed portion 413 and a second toothed portion 414 that mesh with each other. The first toothed portion 413 is fixedly connected to the first channel plate 21 and is coaxially arranged with the first pivot shaft 51. The second toothed portion 414 is fixedly connected to the second channel plate 22 and is coaxially arranged with the second pivot shaft 52. A first gear 411 is used for transmission connection with the second toothed portion 414. This arrangement allows the first channel plate 21 and the second channel plate 22 to be transmissionally connected through the meshing first toothed portion 413 and the second toothed portion 414, so that when one of the first channel plate 21 and the second channel plate 22 rotates, it drives the other to rotate synchronously in the opposite direction. Preferably, the first toothed portion 413 is located at one end of the first channel plate 21 along the axial direction of the first pivot shaft 51, and the second toothed portion 414 is located at one end of the second channel plate 22 along the axial direction of the second pivot shaft 52. More preferably, the transmission assembly 41 includes two first toothed portions 413 and two second toothed portions 414, which mesh in a one-to-one correspondence. The two first toothed portions 413 are respectively fixed to both ends of the first channel plate 21 along the axial direction of the first pivot shaft 51, and the two second toothed portions 414 are respectively fixed to both ends of the second channel plate 22 along the axial direction of the second pivot shaft 52. This arrangement ensures the stability of the transmission connection between the first channel plate 21 and the second channel plate 22. More preferably, both the first toothed portions 413 and the second toothed portions 414 are incomplete gears, and they remain meshed throughout the synchronous rotation of the first channel plate 21 and the second channel plate 22. In other embodiments, the first toothed portions 413 and the second toothed portions 414 can also be configured as complete gears.

[0078] As an alternative, the transmission assembly 41 also includes a first friction wheel and a second friction wheel. The first friction wheel is fixedly connected to the first channel plate 21 and coaxially arranged with the first pivot shaft 51. The second friction wheel is fixedly connected to the second channel plate 22 and coaxially arranged with the second pivot shaft 52. The circumferential surface of the first friction wheel abuts against the circumferential surface of the second friction wheel. One of the first channel plate 21 and the second channel plate 22 drives the other of the two to rotate synchronously in opposite directions through the friction between the first friction wheel and the second friction wheel.

[0079] Alternatively, please refer to Figure 3 , Figure 4 , Figure 8 and Figure 9A first inlet / outlet 24 is formed between the first end of the first channel plate 21 and the first end of the second channel plate 22, and a second inlet / outlet 25 is formed between the second end of the first channel plate 21 and the second end of the second channel plate 22. The sheet-like media conveying device 30 also includes a first limiting part 71 and a second limiting part 72. The first limiting part 71 is connected to the first end of the first channel plate 21, and the second limiting part 72 is connected to the first end of the second channel plate 22. When the constriction is formed by the first inlet / outlet 24 and the opening is formed by the second inlet / outlet 25, the second limiting part 72... The transmission assembly 41 also includes a torque limiter 415. When the motor drives the first pivot shaft 51 to rotate in the first direction and the first limit part 71 and the second limit part 72 are not in contact, the torque limiter 415 enables the first gear 411 to be connected to the second toothed part 414. When the motor drives the first pivot shaft 51 to rotate in the first direction and the first limit part 71 and the second limit part 72 are in contact, the torque limiter 415 enables the first gear 411 to be disconnected from the second toothed part 414. With this configuration, during the process of the motor driving the first pivot shaft 51 to rotate in the first direction, the second limiting part 72 abuts against the first limiting part 71, which can ensure that the first channel plate 21 and the second channel plate 22 rotate into place, that is, the minimum size of the closing opening formed by the first inlet and outlet 24 can remain stable. In addition, when the first limiting part 71 and the second limiting part 72 abut against each other, the torque limiter 415 disconnects the transmission connection between the first gear 411 and the second toothed part 414, which can limit the maximum torque output of the motor, protect the motor from overload, and not hinder the motor from continuing to drive the first pivot shaft 51 to rotate in the first direction. Thus, the motor can continue to drive the first pivot shaft 51 and drive the conveying wheel 31 to rotate synchronously in the first direction, ensuring the driving force of the conveying wheel 31 on the sheet-like medium.

[0080] Alternatively, please refer to Figure 3 and Figure 4 The sheet-type media conveying device 30 also includes a third limiting part 73 and a fourth limiting part 74. The third limiting part 73 is connected to the second end of the first channel plate 21, and the fourth limiting part 74 is connected to the second end of the second channel plate 22. When the constriction is formed by the second inlet / outlet 25 and the opening is formed by the first inlet / outlet 24, the fourth limiting part 74 abuts against the third limiting part 73 to limit the minimum size of the constriction. With this configuration, during the process of the elastic member 43 driving the first channel plate 21 and causing the second channel plate 22 to rotate in the opposite direction, the abutment between the third limiting part 73 and the fourth limiting part 74 can ensure that the first channel plate 21 and the second channel plate 22 rotate into position, that is, the minimum size of the constriction formed by the second inlet / outlet 25 can remain stable. Preferably, the first limiting part 71 and the third limiting part 73 are both integrally formed with the first channel plate 21, and the second limiting part 72 and the fourth limiting part 74 are both integrally formed with the second channel plate 22.

[0081] Alternatively, please refer to Figures 8 to 10 The torque limiter 415 includes a drive shaft 416, a torsion spring 417, a second gear 418, and a third gear 419. The drive shaft 416 is rotatably mounted on the mounting bracket 1; the torsion spring 417 is sleeved on the drive shaft 416, and a set damping is generated between the inner ring of the torsion spring 417 and the drive shaft 416; the second gear 418 is drively connected to the first gear 411, and is sleeved on the torsion spring 417, the torsion spring 417 having a plug-in portion 420, and the inner ring of the second gear 418 having a slot 421, the plug-in portion 420 engaging with the slot 421 to link the second gear 418 and the torsion spring 417; the third gear 419 is fixedly mounted on the drive shaft 416. The first pivot shaft 51 is rotated in the first direction by the motor and the first limiting part 71 and the second limiting part 72 are not in contact. The rotational resistance of the transmission shaft 416 is less than the set damping, and the torsion spring 417 is connected to the transmission shaft 416. When the first pivot shaft 51 is rotated in the first direction by the motor and the first limiting part 71 and the second limiting part 72 are in contact, the rotational resistance of the transmission shaft 416 is greater than the set damping, and the torsion spring 417 and the transmission shaft 416 slip relative to each other. This configuration ensures that when the motor drives the first pivot shaft 51 to rotate in the first direction and the first limiting part 71 and the second limiting part 72 are not in contact, the second pivot shaft 52 drives the second channel plate 22 to rotate sequentially through the first gear 411, the second gear 418, the torsion spring 417, the transmission shaft 416, the third gear 419, and the second toothed part 414. The second channel plate 22 drives the first channel plate 21 to rotate synchronously in the opposite direction through the meshing second toothed part 414 and the first toothed part 413. When the motor drives the first pivot shaft 51 to rotate in the first direction and the first limiting part 71 and the second limiting part 72 are in contact, the torsion spring 417 is disconnected from the transmission shaft 416, and the torsion spring 417 and the transmission shaft 416 slip relative to each other, causing the second gear 418 to rotate with the motor while the third gear 419 does not rotate. This achieves overload protection for the motor and allows the motor to continue driving the first pivot shaft 51 and the conveyor wheel 31 to rotate synchronously in the first direction.

[0082] Alternatively, please refer to Figure 2 The transmission assembly 41 also includes two transmission gears 429, both of which are rotatably mounted on the mounting bracket 1. The two transmission gears 429 mesh with each other, with the first gear 411 meshing with one of the two transmission gears 429 and the second gear 418 meshing with the other of the two transmission gears 429. This arrangement facilitates the spatial arrangement of the first pivot shaft 51 and the transmission shaft 416.

[0083] Alternatively, please refer to Figure 8 and Figure 9The drive shaft 416 includes a shaft body 422 and a drive sleeve 423 fixedly sleeved on the shaft body 422. The shaft body 422 is rotatably mounted on the mounting bracket 1. A torsion spring 417 is sleeved with the drive sleeve 423. Damping is generated between the inner ring of the torsion spring 417 and the outer ring of the drive sleeve 423. A third gear 419 is fixedly sleeved on the shaft body 422.

[0084] Alternatively, please continue to refer to Figure 8 and Figure 9 The torque limiter 415 also includes a pin 424, a limiting groove 426, and a limiting member 425. The shaft 422 has a through hole 427 extending radially through it, and the transmission sleeve 423 has a notch 428. The inner diameter of the through hole 427 and the width of the notch 428 are both adapted to the diameter of the pin 424. The pin 424 is inserted into the through hole 427, and the portion of the pin 424 extending out of the through hole 427 is inserted into the notch 428. The limiting member 425 is sleeved on the transmission sleeve 423 and has two limiting grooves 426. Both ends of the pin 424 are respectively embedded in the two limiting grooves 426. The two limiting grooves 426 are used to jointly limit the displacement of the pin 424 along the extension direction of the through hole 427. This arrangement improves the stability of the connection between the shaft 422 and the transmission sleeve 423.

[0085] As an alternative, the transmission assembly 41 includes a first transmission structure and a second transmission structure. The first pivot shaft 51 is connected to the second channel plate 22 via the first transmission structure. The second transmission structure includes a first toothed portion 413 and a second toothed portion 414 that mesh with each other. The first toothed portion 413 is fixedly connected to the first channel plate 21 and is coaxially arranged with the first pivot shaft 51. The second toothed portion 414 is fixedly connected to the second channel plate 22 and is coaxially arranged with the second pivot shaft 52. When the motor drives the first pivot shaft 51 to rotate in a first direction, the first pivot shaft 51 drives the second channel plate 22 via the first transmission structure. When plate 22 rotates, the second channel plate 22 drives the first channel plate 21 to rotate synchronously in opposite directions through the meshing first toothed portion 413 and the second toothed portion 414, so that the first inlet / outlet 24 forms a closed opening and the second inlet / outlet 25 forms an open opening; when the motor drives the first pivot shaft 51 to rotate in the second direction, the first pivot shaft 51 drives the second channel plate 22 to rotate through the first transmission structure, and the second channel plate 22 drives the first channel plate 21 to rotate synchronously in opposite directions through the meshing first toothed portion 413 and the second toothed portion 414, so that the first inlet / outlet 24 forms an open opening and the second inlet / outlet 25 forms a closed opening, the first direction being opposite to the second direction. With this configuration, the first pivot shaft 51 is connected to the second channel plate 22 via the first transmission structure, and the second channel plate 22 is connected to the first channel plate 21 via the meshing first toothed portion 413 and the second toothed portion 414. When a sheet-like medium needs to move along the direction from the first inlet / outlet 24 to the second inlet / outlet 25, the motor drives the first pivot shaft 51 to rotate in the second direction, which makes the first inlet / outlet 24 open and the second inlet / outlet 25 closed. When a sheet-like medium needs to move along the direction from the second inlet / outlet 25 to the first inlet / outlet 24, the motor drives the first pivot shaft 51 to rotate in the first direction, which makes the second inlet / outlet open and the first inlet / outlet 24 closed.

[0086] As an alternative, the first gear 411 is fixedly sleeved on the first pivot shaft 51. The transmission assembly 41 also includes a first transmission wheel, a second transmission wheel, a first one-way bearing, and a second one-way bearing. Both the first and second transmission wheels are connected to the first gear 411. The first transmission wheel is rotatably connected to the mounting bracket 1 via the first one-way bearing and is used for transmission connection with the first channel plate 21. The second transmission wheel is rotatably connected to the mounting bracket 1 via the second one-way bearing and is used for transmission connection with the second channel plate 22. The first and second one-way bearings are configured such that when the first pivot shaft 51 rotates in a first direction, the inner ring and outer ring of the first one-way bearing are tightly engaged, and the inner ring and outer ring of the second one-way bearing are also tightly engaged. When the first pivot shaft 51 rotates in a second direction, the first one-way bearing... The inner ring of the first one-way bearing and the outer ring of the second one-way bearing slip relative to each other, and the inner ring of the second one-way bearing and the outer ring of the second bearing slip relative to each other. Thus, when the first pivot shaft 51 rotates in the first direction, the first pivot shaft 51 drives the first channel plate 21 to rotate through the first gear and the first transmission wheel, and the first pivot shaft 51 drives the second channel plate 22 to rotate through the first gear and the second transmission wheel, and the rotation directions of the first channel plate 21 and the second channel plate 22 are opposite, so that the first inlet and outlet 24 forms a closed opening and the second inlet and outlet 25 forms an open opening. When the first pivot shaft 51 rotates in the second direction, the first pivot shaft 51 is disconnected from the transmission connection with the first transmission wheel and the second transmission wheel, and there is no power to drive the first channel plate 21 and the second channel plate 22 to rotate. When the first elastic element drives the first channel plate 21 to rotate, the second elastic element drives the second channel plate 22 to rotate in the opposite direction. Specifically, the transmission assembly 41 further includes a first torque limiter and a second torque limiter. The first torque limiter is disposed between the first transmission wheel and the first channel plate 21, and the second torque limiter is disposed between the second transmission wheel and the second channel plate 22. When the motor drives the first pivot shaft 51 to rotate in the first direction and the first limiting part 71 and the second limiting part 72 do not abut, the first torque limiter 415 makes the first transmission wheel drive-connected to the first channel plate 21, and the second torque limiter makes the second transmission wheel drive-connected to the second channel plate 22. When the motor drives the first pivot shaft 51 to rotate in the first direction and the first limiting part 71 and the second limiting part 72 abut, the first torque limiter makes the first transmission wheel disconnected from the first channel plate 21, and the second torque limiter makes the second transmission wheel disconnected from the second channel plate 22.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
