Technical Field

[0001] This application belongs to the field of financial equipment technology, and in particular relates to a transmission device and financial equipment. Background Technology

[0002] In financial media processing equipment, the transmission direction requirements of each channel vary under different business processes.

Related technologies often use multi-motor drives or add reversing clutch mechanisms to meet the transmission direction requirements of different channels. However, the former leads to an increase in the number of power units and higher costs, while the latter results in a complex transmission structure and reduced reliability. Summary of the Invention

[0019] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0020] The following is for reference. Figures 1-8 The transmission device provided according to the embodiments of this application includes a frame 100, a first transmission wheel set 210, a second transmission wheel set 220, and a drive member 310.

[0021] The frame 100 forms a spaced-apart first channel 101 and second channel 102; a first conveyor wheel assembly 210 is movably disposed on the frame 100 and partially placed in the first channel 101; a second conveyor wheel assembly 220 is movably disposed on the frame 100 and partially placed in the second channel 102. It should be noted that the shape and size of the first channel 101 and the second channel 102 can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0022] It should be noted that financial instruments include, but are not limited to, banknotes, checks, bills, and gift certificates.

[0023] It is understandable that the first channel 101 and the second channel 102 are separated, which provides parallel transmission paths for the financial medium. At the same time, the first transmission wheel group 210 realizes the individual transmission control of the financial medium in the first channel 101, and the second transmission wheel group 220 realizes the individual transmission control of the financial medium in the second channel 102, reducing mutual interference between the two, so as to realize different financial business functions at the same time.

[0024] The driving component 310 is dynamically coupled to the first transmission wheel set 210 and the second transmission wheel set 220 respectively, and has a first state and a second state; wherein, The first transmission wheel assembly 210 drives the financial medium to travel in the same direction in both the first and second states. The second transmission wheel assembly 220 always drives the financial medium to travel in one direction in the first state, and stops driving or drives the financial medium to travel in the opposite direction in the second state. The driving component 310 includes, but is not limited to, a servo motor.

[0025] It should be noted that the fixed end of the drive component 310 can be set on the frame 100 or on other parts of the financial equipment. This embodiment does not impose any specific restrictions on this.

[0026] In actual operation, the first conveyor wheel assembly 210, regardless of whether it is in the first or second state, always drives the financial medium to be transported in the same direction within the first channel 101, for example, to realize cash withdrawal or rejection, that is, to unidirectionally recycle the financial medium to a certain area. The second conveyor wheel assembly 220, in the first state, drives the financial medium in the second channel 102 to be transported unidirectionally to realize functions such as cash deposit. In the second state, the second conveyor wheel assembly 220 can stop transporting, for example, pausing transport when there is too much financial medium, or cutting off power when the financial equipment needs maintenance; or, the second conveyor wheel assembly 220 can drive the financial medium to be transported in the opposite direction to realize functions such as cash return or diverting the financial medium to different areas.

[0027] Understandably, on the one hand, by using a single drive unit 310 to simultaneously control the movement of the first transmission wheel group 210 and the second transmission wheel group 220, compared to related technologies where each channel needs to be equipped with at least one independent motor, the number of power sources can be reduced, manufacturing costs and energy consumption can be lowered, and the internal structure of the transmission device can be simplified. On the other hand, by switching between the first and second states, the drive unit 310 can adjust the transmission direction of the financial medium in the second channel 102 or stop the transmission while ensuring that the financial medium in the first channel 101 is always transmitted in one direction. This meets the diverse needs of different business processes for the transmission direction, and eliminates the need for additional reversing mechanisms, clutches, or electromagnetic brakes, simplifying the transmission path and improving the reliability of the transmission device.

[0028] According to the transmission device provided in the embodiments of this application, by using a single driving element 310 to simultaneously drive the first transmission wheel group 210 and the second transmission wheel group 220, and by switching the driving element 310 between the first state and the second state, the unidirectional transmission of the second channel 102 and one of the stop or reverse transmission can be realized, and the transmission direction of the first channel 101 remains constant. Thus, while reducing the number of power sources, simplifying the transmission complexity and improving reliability, it meets the diversified transmission needs under multiple business processes, which is conducive to improving the miniaturization and integration of financial equipment.

[0029] In some embodiments, such as Figures 1 to 6 and Figure 8 As shown, the transmission device also includes: The drive gear 320 is disposed at the output end of the drive member 310, and the rotation direction of the drive gear 320 in the first state is opposite to the rotation direction in the second state. The first drive shaft 410 is rotatably mounted on the frame 100, and is fitted with a first driven gear 510, a second driven gear 520 and a first drive wheel 211 of the first transmission wheel set 210 at intervals; The second drive shaft 420 is rotatably mounted on the frame 100, and is fitted with a first one-way bearing 610, a second one-way bearing 620 and a third driven gear 530 at intervals, and the third driven gear 530 meshes with the drive gear 320. The third drive shaft 430 is rotatably mounted on the frame 100 and is fitted with the third one-way bearing 630 and the second drive wheel 221 of the second transmission wheel set 220; The first mating gear 710 is disposed on the outer ring of the first one-way bearing 610 and is connected to the first driven gear 510 for transmission. The second mating gear 720 is disposed on the outer ring of the second one-way bearing 620 and is connected to the second driven gear 520 for transmission. The third mating gear 730 is located on the outer ring of the third one-way bearing 630 and meshes with the drive gear 320.

[0030] It is understood that the drive gear 320 achieves opposite rotation directions in the first and second states through the output end of the drive member 310, and utilizes the one-way locking and reverse free-running characteristics of the one-way bearings (including at least one of the first one-way bearing 610, the second one-way bearing 620, and the third one-way bearing 630), as well as the transmission connection between the first driven gear 510 and the first mating gear 710 sleeved outside the first one-way bearing 610, the transmission connection between the second driven gear 520 and the second mating gear 720 sleeved outside the second one-way bearing 620, and the drive gear The drive gear 320 is connected to the third driven gear 530 and the third mating gear 730 sleeved on the third one-way bearing 630, respectively. In the first state, the drive gear 320 drives the first drive gear 211 and the second drive gear 221 to rotate. In the second state, it drives the first drive gear 211 to rotate and the second drive gear 221 to stop. That is, the decoupling of the rotation states of the first drive gear 211 and the second drive gear 221 by a single drive component 310 is achieved by a purely mechanical means, which simplifies the complexity of the overall transmission, reduces the cost, and improves the reliability of the transmission device.

[0031] It should be noted that a one-way bearing is a bearing that uses components such as balls / rollers and retainers between its inner and outer rings to allow free rotation of a drive shaft passing through it in one direction, while locking the drive shaft in the other direction and rotating synchronously with it. Specifically, when the one-way bearing is counter-clockwise (i.e., the locking direction is counter-clockwise), when the drive shaft rotates counter-clockwise as the power source, the one-way bearing is locked, and the drive shaft drives the outer ring of the one-way bearing to rotate together, with both relatively stationary. When the drive shaft rotates clockwise as the power source, the one-way bearing is in a free-spinning state, and the drive shaft rotates freely relative to the outer ring of the one-way bearing. When the outer ring of the one-way bearing rotates counter-clockwise as the power source, the one-way bearing is in a free-spinning state and cannot drive the drive shaft to rotate. When the outer ring of the one-way bearing rotates clockwise as the power source, the one-way bearing is in a locked state and drives the drive shaft to rotate together. Conversely, the working characteristics of a clockwise one-way bearing are completely opposite to those of a counter-clockwise one-way bearing, and will not be elaborated upon here. By reasonably selecting the locking direction of the one-way bearing, the rotation state of the first driving gear 211 and the second driving gear 221 can be adjusted by the drive gear 320 under different rotation directions.

[0032] In some embodiments, the controller of the financial device sends a forward or reverse rotation command to the drive member 310 to switch the rotation direction of the drive gear 320 between a first state and a second state, thereby simplifying the control logic and improving reliability. Of course, in other embodiments, a reversing gear set and clutch, or a planetary gear train and brake, can be added between the drive member 310 and the drive gear 320 to achieve a constant output direction of the drive member 310 while switching the rotation direction of the drive gear 320. This embodiment does not impose specific limitations on this.

[0033] In some embodiments, such as Figure 3 and Figure 5 As shown, the locking direction of the first one-way bearing 610 is counterclockwise, while the locking directions of the second one-way bearing 620 and the third one-way bearing 630 are both clockwise. In the first state, the drive gear 320 rotates clockwise relative to the frame 100, the first drive shaft 410 rotates clockwise relative to the frame 100, and the second drive shaft 420 and the third drive shaft 430 rotate counterclockwise relative to the frame 100. In the second state, the drive gear 320 rotates counterclockwise relative to the frame 100, the first drive shaft 410 and the second drive shaft 420 both rotate clockwise relative to the frame 100, and the third drive shaft 430 remains stationary relative to the frame 100.

[0034] It should be noted that, for ease of understanding, clockwise and counterclockwise directions can be referred to as... Figures 3 to 7 As shown by the arrow in the image.

[0035] It is understandable that, such as Figure 3 and Figure 4 As shown, in the first state, the drive gear 320 rotates clockwise, thereby driving the third mating gear 730 and the third driven gear 530 to rotate counterclockwise. The third transmission shaft 430, driven by the third one-way bearing 630 (locked clockwise), rotates counterclockwise to achieve synchronous counterclockwise rotation of the second driving wheel 221. The second transmission shaft 420 rotates counterclockwise via the third driven gear 530, and the first transmission shaft 410 rotates clockwise via the sequential engagement of the first one-way bearing 610 (locked counterclockwise), the first mating gear 710, and the first driven gear 510, to achieve synchronous clockwise rotation of the first driving wheel 211. Simultaneously, the relative rotation between the clockwise-locked second one-way bearing 620 and the counterclockwise-rotating second transmission shaft 420 does not affect the transmission connection between the second mating gear 720 (fitted around the outer ring of the second one-way bearing 620) and the second driven gear 520 (fitted around the first transmission shaft 410), thus preventing interference with the rotation of the first transmission shaft 410.

[0036] In the second state, such as Figure 5 and Figure 6As shown, the drive gear 320 rotates counterclockwise, thereby driving the third mating gear 730 and the third driven gear 530 to rotate clockwise. The third transmission shaft 430 cannot be driven by the third one-way bearing 630 with a clockwise locking direction and remains stationary relative to the frame 100, thus achieving synchronous stationary rotation of the second driving wheel 221. The second transmission shaft 420 rotates clockwise through the third driven gear 530, and the first transmission shaft 410 rotates clockwise through the sequential engagement of the second one-way bearing 620 with a clockwise locking direction, the second mating gear 720, and the second driven gear 520, thus achieving synchronous clockwise rotation of the first driving wheel 211. At the same time, the relative rotation between the first one-way bearing 610 with a counterclockwise locking direction and the clockwise rotating second transmission shaft 420 does not affect the transmission connection between the first mating gear 710 sleeved on the outer ring of the first one-way bearing 610 and the first driven gear 510 sleeved on the outside of the first transmission shaft 410, thus ensuring that the rotation of the first transmission shaft 410 is undisturbed.

[0037] In some other embodiments, the locking directions of the first one-way bearing 610, the second one-way bearing 620, and the third one-way bearing 630 can all be counterclockwise. This can be achieved by simply installing the second one-way bearing 620 and the third one-way bearing 630 in reverse order to the corresponding second drive shaft 420 and third drive shaft 430, respectively. Further details are omitted here.

[0038] In some embodiments, such as Figure 3 , Figure 5 and Figure 8 As shown, a limiting protrusion 701 is provided on one of the inner wall of the third mating gear 730 and the outer ring of the third one-way bearing 630, and a limiting groove 601 is provided on the other. The limiting protrusion 701 and the limiting groove 601 engage in a limiting fit. It should be noted that the shape, number, and size of the limiting protrusion 701 and the limiting groove 601 can be designed according to actual needs, and this embodiment does not impose specific limitations on them. For example, as shown... Figure 3 and Figure 5 As shown, the inner wall of the third mating gear 730 is provided with a limiting protrusion 701, and the outer ring of the third one-way bearing 630 forms a limiting groove 601.

[0039] Understandably, the limiting protrusion 701 and the limiting groove 601 work together to achieve a circumferential fixed connection between the inner ring of the third mating gear 730 and the outer ring of the third one-way bearing 630, thereby improving the reliability of the transmission. Simultaneously, the matching limiting protrusion 701 and the limiting groove 601 improve the efficiency of disassembly and assembly between the third mating gear 730 and the third one-way bearing 630, and facilitate maintenance.

[0040] Of course, in other embodiments, the outer ring of the third mating gear 730 and the third one-way bearing 630 are integrally formed, which can effectively improve the efficiency of momentum conversion, reduce manufacturing costs, and improve assembly efficiency.

[0041] In some embodiments, such as Figure 1 , Figure 3 and Figure 5 As shown, the transmission device also includes: The first intermediate gear 810 and the second intermediate gear 820 mesh with each other. The first intermediate gear 810 meshes with the first driven gear 510, and the second intermediate gear 820 meshes with the first mating gear 710. The third intermediate gear 830 meshes with the second driven gear 520 and the second mating gear 720.

[0042] Understandably, in the first state, such as Figure 3 and Figure 4 As shown, the drive gear 320 rotates clockwise, thereby driving the third mating gear 730 and the third driven gear 530 to rotate counterclockwise. The third transmission shaft 430 rotates counterclockwise under the drive of the third one-way bearing 630, which is locked in a clockwise direction, so as to realize the synchronous counterclockwise rotation of the second driving wheel 221. The second transmission shaft 420 rotates counterclockwise through the third driven gear 530. The first transmission shaft 410 rotates clockwise through the sequential engagement of the first one-way bearing 610, the first mating gear 710, the second intermediate gear 820, the first intermediate gear 810, and the first driven gear 510, which are locked in a counterclockwise direction, so as to realize the synchronous clockwise rotation of the first driving wheel 211. Meanwhile, the relative rotation between the second one-way bearing 620, which is locked in a clockwise direction, and the second drive shaft 420, which rotates counterclockwise, does not affect the sequential meshing between the second mating gear 720, the third intermediate gear 830, which is sleeved on the outer ring of the second one-way bearing 620, and the second driven gear 520, which is sleeved on the outer ring of the first drive shaft 410, thus ensuring that the rotation of the first drive shaft 410 is free from interference.

[0043] In the second state, such as Figure 5 and Figure 6As shown, the drive gear 320 rotates counterclockwise, thereby driving the third mating gear 730 and the third driven gear 530 to rotate clockwise. The third transmission shaft 430 cannot be driven by the third one-way bearing 630 with the locking direction clockwise and remains stationary relative to the frame 100, so as to realize the synchronous stationary of the second driving wheel 221. The second transmission shaft 420 rotates clockwise through the third driven gear 530. The first transmission shaft 410 rotates clockwise through the sequential engagement of the second one-way bearing 620 with the locking direction clockwise, the second mating gear 720, the third intermediate gear 830 and the second driven gear 520, so as to realize the synchronous clockwise rotation of the first driving wheel 211. Meanwhile, the relative rotation between the first one-way bearing 610, which is locked in a counterclockwise direction, and the second drive shaft 420, which rotates clockwise, does not affect the sequential meshing between the first mating gear 710, the second intermediate gear 820, the first intermediate gear 810, which is sleeved on the outer ring of the first one-way bearing 610, and the first driven gear 510, which is sleeved on the outside of the first drive shaft 410, thus ensuring that the rotation of the first drive shaft 410 is free from interference.

[0044] In other embodiments, reference is made to Figure 3 and Figure 4 and combined Figure 7 As shown, the transmission device also includes: The drive gear 320 is disposed at the output end of the drive member 310, and the rotation direction of the drive gear 320 in the first state is opposite to the rotation direction in the second state. The first drive shaft 410 is provided with a first driven gear 510, a second driven gear 520 and a first drive wheel 211 of the first transmission wheel set 210, which are spaced apart. The second drive shaft 420 is fitted with a first one-way bearing 610, a second one-way bearing 620 and a third driven gear 530 at intervals. The locking direction of the first one-way bearing 610 is opposite to that of the second one-way bearing 620, and the third driven gear 530 meshes with the drive gear 320. The third drive shaft 430 is fitted with the second drive wheel 221 of the fourth driven gear and the second transmission wheel set 220, and the fourth driven gear meshes with the drive gear 320; The first mating gear 710 is disposed on the outer ring of the first one-way bearing 610 and is connected to the first driven gear 510 for transmission. The second mating gear 720 is disposed on the outer ring of the second one-way bearing 620 and is connected to the second driven gear 520 for transmission.

[0045] It is understood that the drive gear 320 achieves opposite rotation directions in the first and second states through the output end of the drive member 310, and through the one-way bearing 610 and the second one-way bearing 620 with their one-way locking and reverse free-running characteristics, as well as the transmission connection between the first driven gear 510 and the first mating gear 710 sleeved outside the first one-way bearing 610, the transmission connection between the second driven gear 520 and the second mating gear 720 sleeved outside the second one-way bearing 620, and the drive gear 320 respectively connected to the third driven gear 530 and the fourth driven gear. The transmission connection (that is, the third one-way bearing 630 and the third mating gear 730 in the previous embodiment are replaced by the fourth driven gear) allows the drive gear 320 to drive the first driving wheel 211 and the second driving wheel 221 to rotate in the first state, and drive the first driving wheel 211 to rotate and the second driving wheel 221 to reverse in the second state. In other words, the decoupling of the rotation states of the first driving wheel 211 and the second driving wheel 221 by a single drive component 310 is achieved by a purely mechanical means, which simplifies the complexity of the overall transmission, reduces the cost, and improves the reliability of the transmission device.

[0046] In some embodiments, the locking direction of the first one-way bearing 610 is counterclockwise, and the locking direction of the second one-way bearing 620 is clockwise, wherein: In the first state, the drive gear 320 rotates clockwise relative to the frame 100, the first drive shaft 410 rotates clockwise relative to the frame 100, and the second drive shaft 420 and the third drive shaft 430 both rotate counterclockwise relative to the frame 100. In the second state, the drive gear 320 rotates counterclockwise relative to the frame 100, and the first drive shaft 410, the second drive shaft 420, and the third drive shaft 430 all rotate clockwise relative to the frame 100.

[0047] Understandably, in the first state, reference Figure 3 and Figure 4 As shown, the drive gear 320 rotates clockwise, thereby driving the third driven gear 530 and the fourth driven gear to rotate counterclockwise. The third transmission shaft 430 rotates counterclockwise under the drive of the fourth driven gear, achieving synchronous counterclockwise rotation of the second driving wheel 221. The second transmission shaft 420 rotates counterclockwise via the third driven gear 530, and the first transmission shaft 410 rotates clockwise via the sequential engagement of the first one-way bearing 610 (locked counterclockwise), the first mating gear 710, and the first driven gear 510, achieving synchronous clockwise rotation of the first driving wheel 211. Simultaneously, the relative rotation between the clockwise-locked second one-way bearing 620 and the counterclockwise-rotating second transmission shaft 420 does not affect the transmission connection between the second mating gear 720 (fitted around the outer ring of the second one-way bearing 620) and the second driven gear 520 (fitted around the first transmission shaft 410), thus preventing interference with the rotation of the first transmission shaft 410.

[0048] In the second state, such as Figure 7 As shown, and with reference Figure 5 and Figure 6 The drive gear 320 rotates counterclockwise, thereby driving the fourth driven gear and the third driven gear 530 to rotate clockwise. The third drive shaft 430 rotates clockwise under the drive of the fourth driven gear, achieving synchronous clockwise rotation of the second drive wheel 221. The second drive shaft 420 rotates clockwise via the third driven gear 530. The first drive shaft 410 rotates clockwise via the sequential engagement of the second one-way bearing 620 (locked clockwise), the second mating gear 720, and the second driven gear 520, achieving synchronous clockwise rotation of the first drive wheel 211. Simultaneously, the relative rotation between the first one-way bearing 610 (locked counterclockwise) and the clockwise rotating second drive shaft 420 does not affect the transmission connection between the first mating gear 710 (fitted around the outer ring of the first one-way bearing 610) and the first driven gear 510 (fitted around the first drive shaft 410), thus preventing interference with the rotation of the first drive shaft 410.

[0049] In some other embodiments, the locking direction of the first one-way bearing 610 and the second one-way bearing 620 can both be counterclockwise. This can be achieved by simply installing the second one-way bearing 620 in the opposite direction on the second drive shaft 420. Further details are omitted here.

[0050] In some embodiments, reference Figure 3 and Figure 5 As shown, the transmission device also includes: The first intermediate gear 810 and the second intermediate gear 820 mesh with each other. The first intermediate gear 810 meshes with the first driven gear 510, and the second intermediate gear 820 meshes with the first mating gear 710. The third intermediate gear 830 meshes with the second driven gear 520 and the second mating gear 720.

[0051] Understandably, in the first state, the drive gear 320 rotates clockwise, thereby driving the third mating gear 730 and the third driven gear 530 to rotate counterclockwise. The third transmission shaft 430 rotates counterclockwise under the drive of the fourth driven gear, thus realizing the synchronous counterclockwise rotation of the second driving wheel 221. The second transmission shaft 420 rotates counterclockwise through the third driven gear 530. The first transmission shaft 410 rotates clockwise through the sequential engagement of the first one-way bearing 610 (locked counterclockwise), the first mating gear 710, the second intermediate gear 820, the first intermediate gear 810, and the first driven gear 510, thus realizing the synchronous clockwise rotation of the first driving wheel 211. Meanwhile, the relative rotation between the second one-way bearing 620, which is locked in a clockwise direction, and the second drive shaft 420, which rotates counterclockwise, does not affect the sequential meshing between the second mating gear 720, the third intermediate gear 830, which is sleeved on the outer ring of the second one-way bearing 620, and the second driven gear 520, which is sleeved on the outer ring of the first drive shaft 410, thus ensuring that the rotation of the first drive shaft 410 is free from interference.

[0052] In the second state, the drive gear 320 rotates counterclockwise, thereby driving the third mating gear 730 and the third driven gear 530 to rotate clockwise. The third transmission shaft 430 rotates clockwise under the drive of the fourth driven gear to achieve synchronous clockwise rotation of the second driving wheel 221. The second transmission shaft 420 rotates clockwise through the third driven gear 530. The first transmission shaft 410 rotates clockwise through the sequential engagement of the second one-way bearing 620 (locked clockwise), the second mating gear 720, the third intermediate gear 830, and the second driven gear 520 to achieve synchronous clockwise rotation of the first driving wheel 211. Meanwhile, the relative rotation between the first one-way bearing 610, which is locked in a counterclockwise direction, and the second drive shaft 420, which rotates clockwise, does not affect the sequential meshing between the first mating gear 710, the second intermediate gear 820, the first intermediate gear 810, which is sleeved on the outer ring of the first one-way bearing 610, and the first driven gear 510, which is sleeved on the outside of the first drive shaft 410, thus ensuring that the rotation of the first drive shaft 410 is free from interference.

[0053] In some embodiments, such as Figure 3 , Figure 5 and Figure 7 As shown, a limiting protrusion 701 is provided on one of the inner wall of the first mating gear 710 and the outer ring of the first one-way bearing 610, and a limiting groove 601 is provided on the other. The limiting protrusion 701 and the limiting groove 601 engage in a limiting fit. It should be noted that the shape, number, and size of the limiting protrusion 701 and the limiting groove 601 can be designed according to actual needs, and this embodiment does not impose specific limitations on them. For example, as shown... Figure 3 , Figure 5 and Figure 7 As shown, the inner wall of the first mating gear 710 is provided with a limiting protrusion 701, and the outer ring of the first one-way bearing 610 forms a limiting groove 601.

[0054] Understandably, the limiting protrusion 701 and the limiting groove 601 work together to achieve a circumferential fixed connection between the inner ring of the first mating gear 710 and the outer ring of the first one-way bearing 610, thereby improving the reliability of the transmission. Simultaneously, the matching limiting protrusion 701 and the limiting groove 601 improve the efficiency of disassembly and assembly between the first mating gear 710 and the first one-way bearing 610, and facilitate maintenance.

[0055] Of course, in other embodiments, the outer rings of the first mating gear 710 and the first one-way bearing 610 are integrally formed, which can effectively improve the efficiency of momentum conversion, reduce manufacturing costs, and improve assembly efficiency.

[0056] In some embodiments, such as Figure 3 , Figure 5 and Figure 7 As shown, a limiting protrusion 701 is provided on the inner wall of the second mating gear 720 and on one of the outer rings of the second one-way bearing 620, and a limiting groove 601 is provided on the other of the inner wall of the second mating gear 720 and on the outer ring of the second one-way bearing 620. The limiting protrusion 701 and the limiting groove 601 engage in a limiting fit. It should be noted that the shape, number, and size of the limiting protrusion 701 and the limiting groove 601 can be designed according to actual needs, and this embodiment does not impose specific limitations on them. For example, as shown... Figure 3 and Figure 5 As shown, the inner wall of the second mating gear 720 is provided with a limiting protrusion 701, and the outer ring of the second one-way bearing 620 forms a limiting groove 601.

[0057] Understandably, the limiting protrusion 701 and the limiting groove 601 work together to achieve a circumferential fixed connection between the inner ring of the second mating gear 720 and the outer ring of the second one-way bearing 620, thereby improving the reliability of the transmission. Simultaneously, the matching limiting protrusion 701 and the limiting groove 601 improve the efficiency of disassembly and assembly between the second mating gear 720 and the second one-way bearing 620, and facilitate maintenance.

[0058] Of course, in other embodiments, the outer rings of the second mating gear 720 and the second one-way bearing 620 are integrally formed, which can effectively improve the efficiency of momentum conversion, reduce manufacturing costs, and improve assembly efficiency.

[0059] In some embodiments, such as Figure 8As shown, the inner wall of the limiting groove 601 includes a first arc surface 6011, and the outer wall of the limiting protrusion 701 includes a second arc surface 7011. The first arc surface 6011 and the second arc surface 7011 are in contact with each other. It should be noted that the radii of curvature of the first arc surface 6011 and the second arc surface 7011 can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0060] It is understandable that by setting the inner wall of the limiting groove 601 as the first arc surface 6011 and the outer wall of the limiting protrusion 701 as the second arc surface 7011, and making the two fit together, self-centering positioning can be achieved, reducing assembly deviation and difficulty. Furthermore, the contact between the first arc surface 6011 and the second arc surface 7011 can improve the uniformity of stress distribution and extend the service life of the transmission device. Fourthly, when disassembly and assembly are required, the arc surface has good guiding properties, making it easy to insert and pull out, thus reducing assembly difficulty.

[0061] In some embodiments, such as Figure 3 and Figure 5 As shown, the first driven gear 510 and the second driven gear 520 are located on both sides of the first driving wheel 211 along the axial direction of the first transmission shaft 410.

[0062] It is understandable that by setting the first driven gear 510 and the second driven gear 520 on both sides of the first driving wheel 211 along the axial direction of the first drive shaft 410, the torque input on the first drive shaft 410 is symmetrically distributed on both sides of the first driving wheel 211, thereby reducing the off-center load phenomenon caused by always driving on one side when switching states, which is beneficial to extending service life and improving space utilization.

[0063] In some embodiments, such as Figure 3 and Figure 5 As shown, the first one-way bearing 610 and the third driven gear 530 are located at both ends of the second transmission shaft 420, and the second one-way bearing 620 is positioned close to the third driven gear 530.

[0064] Understandably, by placing the first one-way bearing 610 and the third driven gear 530 at opposite ends of the second transmission shaft 420, the off-center load phenomenon caused by always driving on one side during state switching is reduced, which helps to extend service life and improve space utilization. Furthermore, by arranging the second one-way bearing 620 close to the third driven gear 530, the third driven gear 530, as the power input end, can transmit power to the second one-way bearing 620 via a short path, reducing torsional deformation and bending stress on the second transmission shaft 420, and improving transmission accuracy and stability.

[0065] In some embodiments, such as Figure 2 , Figure 4 , Figure 6 and Figure 7As shown, the first channel 101 and the second channel 102 are spaced apart in the vertical direction. Exemplarily, the first channel 101 is located above the second channel 102. Of course, in other embodiments, the second channel 102 may also be located above the first channel 101, and this embodiment does not impose any specific limitations on this.

[0066] Understandably, the vertical arrangement of the first channel 101 and the second channel 102 helps reduce the horizontal width of the frame 100, making the transmission device more compact and adapting to the miniaturization and flattening requirements of financial equipment. Simultaneously, the vertically spaced arrangement naturally separates the first channel 101 and the second channel 102, reducing the possibility of mutual interference when financial media are transmitted in different channels and lowering the risk of jamming or cross-contamination.

[0067] In some embodiments, such as Figure 2 As shown, the frame 100 includes two oppositely arranged side plates 110, a first upper channel plate 120, a first lower channel plate 130, a second upper channel plate 140, and a second lower channel plate 150. The first upper channel plate 120, the first lower channel plate 130, the second upper channel plate 140, and the second lower channel plate 150 are sequentially arranged from top to bottom between the two side plates 110. A first channel 101 is formed between the first upper channel plate 120 and the first lower channel plate 130, and a second channel 102 is formed between the second upper channel plate 140 and the second lower channel plate 150. Of course, in other embodiments, the second channel 102 may be located above the first channel 101; this embodiment does not impose specific limitations on this.

[0068] Understandably, by utilizing two opposing side plates 110 and a first upper channel plate 120, a first lower channel plate 130, a second upper channel plate 140, and a second lower channel plate 150 arranged sequentially from top to bottom between the two side plates 110, a first channel 101 is formed between the first upper channel plate 120 and the first lower channel plate 130, and a second channel 102 is formed between the second upper channel plate 140 and the second lower channel plate 150. This integrates two independent first channels 101 and second channels 102 within a limited space using a simple stacked structure, which is beneficial for the miniaturization and integration of financial equipment. Furthermore, the independent channel plates (including the first upper channel plate 120, the first lower channel plate 130, the second upper channel plate 140, and the second lower channel plate 150) for the first channel 101 and the second channel 102 allow for individual control of the gaps between the two channels, adapting to the transmission requirements of different financial media thicknesses under various functions.

[0069] In some embodiments, such as Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, the first channel 101 includes an arc segment, and the center of curvature of the arc segment is located above the first channel 101.

[0070] Understandably, by including an arc-shaped segment in the first channel 101, and positioning the center of curvature of this arc-shaped segment above the first channel 101 (i.e., the arc-shaped segment bends downwards), the risk of bending or jamming of the financial medium during transmission can be effectively reduced, improving the smoothness and reliability of transmission. Simultaneously, it helps the financial medium to adhere closely to the lower wall of the first channel 101 within the arc-shaped segment, reducing the possibility of the financial medium tilting or deviating. Furthermore, the arc-shaped segment allows for a natural transition in the transmission direction within a limited space, facilitating the compactness of the transmission device and financial equipment.

[0071] In some embodiments, such as Figure 2 , Figure 4 , Figure 6 and Figure 7 As shown, the second channel 102 includes an inclined section that slopes downwards in the horizontal direction, and the second conveying wheel assembly 220, in the first state, clamps the financial medium and conveys it to the upper end of the inclined section. It should be noted that the size and angle of the inclined section can be designed according to actual needs, and this embodiment does not impose specific limitations on them.

[0072] It is understood that by including an inclined section that slopes downward in the horizontal direction in the second channel 102 and having the second transmission wheel set 220 clamp the financial medium and transmit it to the upper end of the inclined section in the first state, it helps to maintain the appropriate tension of the financial medium during transmission in the first state and make full use of gravity to reduce wrinkles or stacking, improve the smoothness and reliability of transmission, and also make full use of the limited space inside the financial equipment, thereby improving the compactness of the transmission device and the financial equipment.

[0073] In some embodiments, such as Figure 1 and Figure 2 As shown, the first transmission wheel assembly 210 includes a first driving wheel 211, a first driven wheel, and a first mating wheel. The first driven wheel is rotatably mounted on the frame 100 and works with the first driving wheel 211 to clamp the financial equipment. The first mating wheel is sleeved on the outside of the first mating shaft. The first mating shaft is rotatably mounted on the frame 100 and is connected to the first transmission shaft 410 via a synchronous belt structure 900, thereby achieving synchronous rotation of the first mating wheel and the first driving wheel 211, thus improving the transmission distance, accuracy, and reliability.

[0074] It should be noted that the number and specific distribution of the first mating shaft, the first mating pulley, the synchronous belt structure 900, and the first driven pulley can be adjusted according to the shape of the first channel 101, and this embodiment does not impose specific limitations on this. The synchronous belt structure 900 includes, but is not limited to, synchronous belts and pulleys, which are common technical means in the field and will not be described in detail. Multiple first driven pulleys can be provided, with some first driven pulleys clamping the first driving pulley 211 and others clamping the first mating pulley; this embodiment does not impose specific limitations on this.

[0075] Similarly, such as Figure 1 and Figure 2 As shown, the second transmission wheel assembly 220 includes a second driving wheel 221, a second driven wheel, and a second mating wheel. The second driven wheel is rotatably mounted on the frame 100 and works with the second driving wheel 221 to clamp the financial equipment. The second mating wheel is sleeved on the outside of the second mating shaft. The second mating shaft is rotatably mounted on the frame 100 and is connected to the third transmission shaft 430 via a synchronous belt structure 900, thereby achieving synchronous rotation of the second mating wheel and the second driving wheel 221, thus improving the transmission distance, accuracy, and reliability.

[0076] It should be noted that the number and specific distribution of the second mating shaft, the second mating pulley, the synchronous belt structure 900, and the second driven pulley can be adjusted according to the shape of the second channel 102, and this embodiment does not impose specific limitations on this. Multiple second driven pulleys can be provided, with some second driven pulleys clamping the first driving pulley 211, and other second driven pulleys clamping at least some of the second mating pulleys; this embodiment does not impose specific limitations on this.

[0077] This application also provides a financial device that includes the aforementioned transmission device.

[0078] It should be noted that financial equipment includes, but is not limited to, ATMs, self-service terminals, banknote counting machines, sorting machines, and banknote bundling machines.

[0079] According to the financial equipment provided in the embodiments of this application, by using a single drive unit 310 to simultaneously drive the first transmission wheel group 210 and the second transmission wheel group 220 in the transmission device, and by switching the drive unit 310 between the first state and the second state, the unidirectional transmission of the second channel 102 and one of the stop or reverse transmission can be realized, and the transmission direction of the first channel 101 remains constant. In this way, while reducing the number of power sources, simplifying the transmission complexity and improving reliability, the diverse transmission needs under multiple business processes are met, which is conducive to improving the miniaturization and integration of financial equipment.
