Description

Technical Field

[0001] This invention relates to the field of financial equipment technology, and in particular to a banknote feeding structure and a banknote machine. Background Technology

[0002] Existing banknote feeding machines mostly use opposing roller structures to roll and transport banknotes. During this process, because the rollers press the banknotes tightly, it is difficult to move the banknotes to center them. The rollers need to be lifted first before the banknotes can be centered. There are too many steps in the banknote feeding and centering process, resulting in low banknote feeding efficiency. Summary of the Invention

[0003] The main objective of this invention is to propose a banknote feeding structure and banknote machine that simultaneously realizes the transport and central processing of banknotes, thereby improving the efficiency of banknote feeding.

[0004] To achieve the above objectives, the present invention proposes a banknote feeding structure, comprising:

[0005] Mounting frame, wherein the mounting frame forms a conveying channel; A conveying assembly is connected to the mounting frame. The conveying assembly includes a driving wheel, a driven wheel, and a first driving member. The driving wheel and the driven wheel are partially exposed in the conveying channel. The output end of the first driving member is connected to the driving wheel to drive the driving wheel to roll and convey banknotes along the extension direction of the conveying channel. The centering component includes two sets of adjusting members and a second driving member. The two sets of adjusting members are arranged facing each other along the width direction of the conveying channel. Both adjusting members have a contact surface facing the conveying channel. The output end of the second driving member is connected to the two adjusting members and can drive the two adjusting members to move closer to each other to push the driven wheel away from the driving wheel, and cause the contact surfaces on the two adjusting members to push and adjust the position of the banknote.

[0006] In one embodiment, the conveying assembly further includes a connecting rod, the driven wheel is sleeved on the connecting rod and can rotate relative to the connecting rod, and both ends of the connecting rod in the length direction are provided with connecting portions, one of the connecting portions abutting against an adjusting member.

[0007] In one embodiment, the top end of the adjusting member is provided with a pushing part, the side of the pushing part facing the connecting part is provided with a first pushing surface, and the connecting part is provided with a second pushing surface corresponding to the first pushing surface. The first pushing surface and the second pushing surface are inclined surfaces arranged facing each other.

[0008] In one embodiment, the connecting portion has a conical structure, and the width of the connecting portion gradually increases along the direction close to the driven wheel.

[0009] In one embodiment, the centering component further includes a rolling element, each of the adjusting elements having a mounting groove, the rolling element being engaged in the mounting groove and facing the connecting portion, the rolling element being positioned in the extension direction of the first pushing surface and located on the side of the pushing portion away from the connecting portion.

[0010] In one embodiment, a limiting groove is formed on the side of both adjusting members facing the conveying channel, and the abutment surface is provided in the limiting groove.

[0011] In one embodiment, the banknote feeding structure further includes a buffer assembly, which includes a mounting component, a top plate, and an elastic element. The mounting component is connected to the side of the connecting rod facing away from the drive wheel, the top plate is fixedly connected to the mounting frame, and the two ends of the elastic element abut against the mounting component and the top plate, respectively.

[0012] In one embodiment, the mounting member extends along the side opposite to the drive wheel and forms a guide post and a guide groove, the elastic member is sleeved on the guide post, and the outer peripheral wall of the elastic member is engaged in the guide groove.

[0013] In one embodiment, the centering component further includes a transmission mechanism, which includes a transmission worm and a mounting rod. The mounting rod is connected to the mounting frame. Two adjusting members are respectively sleeved on both ends of the mounting rod along the axial direction and can slide back and forth along the axial direction of the mounting rod. The transmission worm is connected to the output end of the second driving member. The two ends of the transmission worm along the axial direction are provided with helical teeth with opposite directions of rotation. One of the adjusting members is correspondingly engaged with the helical teeth.

[0014] The present invention also proposes a banknote machine, the banknote machine comprising a banknote feeding structure, and The housing has an installation cavity and a banknote inlet formed inside it. The banknote feeding structure is installed in the installation cavity, and the conveying channel is provided corresponding to the banknote inlet.

[0015] The banknote feeding structure includes a mounting frame, which forms a conveying channel; A conveying assembly is connected to the mounting frame. The conveying assembly includes a driving wheel, a driven wheel, and a first driving member. The driving wheel and the driven wheel are partially exposed in the conveying channel. The output end of the first driving member is connected to the driving wheel to drive the driving wheel to roll and convey banknotes along the extension direction of the conveying channel. The centering component includes two sets of adjusting members and a second driving member. The two sets of adjusting members are arranged facing each other along the width direction of the conveying channel. Both adjusting members have a contact surface facing the conveying channel. The output end of the second driving member is connected to the two adjusting members and can drive the two adjusting members to move closer to each other to push the driven wheel away from the driving wheel, and cause the contact surfaces on the two adjusting members to push and adjust the position of the banknote.

[0016] The present invention proposes a banknote feeding structure, including a mounting frame, a conveying assembly, and a centering assembly. A through conveying channel is formed inside the mounting frame. The conveying assembly is fixedly connected to the mounting frame and includes a driving wheel, a driven wheel, and a first driving member. The centering assembly includes two sets of adjusting members and a second driving member. The two sets of adjusting members are symmetrically arranged facing each other along the width of the conveying channel, and their sides facing the channel have a contact surface that can apply a pushing force to the edge of the banknote. After the first driving member is activated, it drives the driving wheel to rotate. The driving wheel moves the banknote through friction, and simultaneously drives the driven wheel to roll synchronously, forming a clamping and conveying force on the banknote, moving the banknote along the extension direction of the conveying channel. During this process, the second driving member drives the two sets of adjusting members to move closer to each other. As the adjusting members move, they push the driven wheel away from the driving wheel, causing the driven wheel to gradually move away from the banknote. Sufficient gaps are created between the driving wheel and the driven wheel to facilitate banknote movement. Simultaneously, the contact surfaces gradually contact the two edges of the banknote, pushing the banknote towards the center of the channel, thus completing the banknote position correction. This structure simultaneously achieves banknote delivery and centering correction, ensuring standardized banknote delivery posture, effectively reducing the probability of banknote jams and recognition failures, and helping to improve the stability and accuracy of banknote feeding in financial equipment.

[0024] Existing banknote feeding machines mostly use opposing roller structures to roll and transport banknotes. During this process, because the rollers press the banknotes tightly, it is difficult to move the banknotes to center them. The rollers need to be lifted first before the banknotes can be centered. There are too many steps in the banknote feeding and centering process, resulting in low banknote feeding efficiency.

[0025] To solve the above problems, please refer to... Figures 1 to 3 This invention proposes a banknote feeding structure 10, including a mounting frame 1, a conveying assembly 2, and a centering assembly 3. The mounting frame 1 forms a conveying channel. The conveying assembly 2 is connected to the mounting frame 1 and includes a driving wheel 21, a driven wheel 22, and a first driving member. The driving wheel 21 and the driven wheel 22 are partially exposed in the conveying channel. The output end of the first driving member is connected to the driving wheel 21 to drive the driving wheel 22 to roll and convey the banknotes along the extension direction of the conveying channel. The centering assembly 3 includes two sets of adjusting members 31 and a second driving member 32. The two sets of adjusting members 31 are arranged facing each other along the width direction of the conveying channel. Both adjusting members 31 have a contact surface facing the conveying channel. The output end of the second driving member 32 is connected to the two adjusting members 31 and can drive the two adjusting members 31 to move closer to each other to push the driven wheel 22 away from the driving wheel 21, and cause the contact surfaces on the two adjusting members 31 to push and adjust the position of the banknotes.

[0026] The present invention provides a banknote feeding structure 10, applicable to financial automation equipment such as automatic deposit machines, banknote sorting machines, and banknote counting machines. The banknotes are moved along a conveying channel by a conveying component 2, and the banknote position is adjusted by a centering component 3, ensuring that the banknotes are always conveyed along the central axis of the channel, avoiding problems such as banknote jamming and recognition errors caused by banknote offset or skew. The banknote feeding structure 10 includes a mounting frame 1, a conveying component 2, and a centering component 3. A through conveying channel is formed inside the mounting frame 1, the width of which is adapted to the banknote size, providing a stable mounting reference for the conveying component 2 and the centering component 3, while guiding the directional movement of the banknotes. The conveying component 2 is fixedly connected to the mounting frame 1 and includes a driving wheel 21, a driven wheel 22, and a first driving component. The driving wheel 21 and the driven wheel 22 can be made of wear-resistant rubber with anti-slip textures on the surface to enhance friction with the banknotes. Both are partially exposed in the conveying channel, forming a clamping and conveying structure. The first drive unit can be a DC servo motor, providing stable power output and precise speed regulation. Its output end is connected to the drive wheel 21 via a coupling, providing rotational power to the drive wheel 21. The central assembly 3 includes two sets of adjusting members 31 and a second drive unit 32. The two sets of adjusting members 31 are symmetrically arranged facing each other along the width of the conveying channel. Each set has an abutment surface on its channel-facing side, allowing it to apply thrust against the edge of the banknote. The second drive unit 32 can be a stepper motor, providing high-precision position control. Its output end is connected to the two sets of adjusting members 31, driving them to move synchronously. After the first drive unit starts, it drives the drive wheel 21 to rotate. The drive wheel 21 moves the banknote through friction, simultaneously driving the driven wheel 22 to roll synchronously, creating a clamping and conveying force on the banknote, moving it along the extension direction of the conveying channel. During this process, the second driving component 32 drives the two sets of adjusting components 31 to move closer to each other. As the adjusting components 31 move, they push the driven wheel 22 away from the driving wheel 21, causing the driven wheel 22 to gradually move away from the banknote. Sufficient gap is created between the driving wheel 21 and the driven wheel 22 to facilitate banknote movement. Simultaneously, the contact surface gradually conforms to the two edges of the banknote, pushing it towards the center of the channel, thus completing the banknote position correction. This structure simultaneously achieves banknote delivery and centering correction, ensuring standardized banknote delivery posture, effectively reducing the probability of banknote jams and recognition malfunctions, and contributing to improving the stability and accuracy of banknote feeding in financial equipment.

[0027] Furthermore, in one embodiment, please refer to Figures 1 to 3 The conveying assembly 2 also includes a connecting rod 23, a driven wheel 22 is sleeved on the connecting rod 23 and can rotate relative to the connecting rod 23, and both ends of the connecting rod 23 in the length direction are provided with connecting parts 231, one connecting part 231 abutting against an adjusting member 31.

[0028] The conveying assembly 2 also includes a connecting rod 23. The surface of the connecting rod 23 is smoothed, providing good wear resistance and stability. Its axis is parallel to the width direction of the conveying channel. The driven wheel 22 is sleeved on the outside of the connecting rod 23 and connected to the connecting rod 23 via a bearing. It can rotate freely relative to the connecting rod 23, ensuring that the driven wheel 22 rotates synchronously with the banknotes during conveying, reducing frictional damage to the banknotes. Both ends of the connecting rod 23 along its length are integrally formed with connecting portions 231. The connecting portions 231 are coaxially arranged with the axis of the connecting rod 23. Each connecting portion 231 abuts against an adjusting member 31, and the thrust of the adjusting member 31 drives the connecting rod 23 and the driven wheel 22 to move as a whole. The connecting rod 23 provides precise mounting support for the driven wheel 22, ensuring that the axis of the driven wheel 22 is parallel to the axis of the driving wheel 21, thus guaranteeing the stability of the clamping and conveying. The connecting part 231 acts as the force transmission carrier between the adjusting member 31 and the connecting rod 23, converting the thrust of the adjusting member 31 into the displacement force of the connecting rod 23, which drives the driven wheel 22 to move away from or towards the driving wheel 21, adapting to the clamping requirements of banknotes of different thicknesses. When the adjusting members 31 move closer to each other, the adjusting member 31 pushes the connecting part 231, which in turn drives the connecting rod 23 to move away from the driving wheel 21. The driven wheel 22 moves synchronously with the connecting rod 23, increasing the distance between the driving wheel 21 and the driven wheel 22, so that the adjusting member 31 can push the banknote to the center for adjustment. When the adjusting member 31 returns to its original position, the driving wheel 21 and the driven wheel 22 return to their initial distance, continuing to stably clamp and convey banknotes. The connection rod 23 and the connection part 231 enable the linkage adjustment of the position of the driven wheel 22, which not only works with the centering component 3 to complete the banknote correction, but also ensures the clamping adaptability of the conveying component 2 and improves the overall reliability of the banknote feeding structure 10.

[0029] In one embodiment, please refer to Figures 2 to 4 The top of the adjusting member 31 is provided with a pushing part 311. The side of the pushing part 311 facing the connecting part 231 is provided with a first pushing surface 311a. The connecting part 231 is provided with a second pushing surface 231a corresponding to the first pushing surface 311a. The first pushing surface 311a and the second pushing surface 231a are inclined surfaces arranged facing each other.

[0030] The top of the adjusting member 31 is integrally formed with a pushing part 311, and a first pushing surface 311a is machined on the side facing the connecting part 231. The connecting part 231 has a second pushing surface 231a machined at the position corresponding to the first pushing surface 311a. Both the first and second pushing surfaces 311a are opposing inclined surfaces with the same inclination angle. When fitted together, they can achieve vertical force transmission, converting the horizontal thrust of the adjusting member 31 into the vertical or lateral displacement force of the connecting rod 23. The pushing part 311 provides a mounting carrier for the first pushing surface 311a, ensuring the machining accuracy and stability of the inclined structure, while also increasing the contact area between the adjusting member 31 and the connecting part 231, avoiding excessive local stress that could lead to component wear. The inclined surfaces of the first pushing surface 311a and the second pushing surface 231a reduce the frictional resistance between the adjusting component 31 and the connecting part 231, making the force transmission smoother and preventing jamming. Simultaneously, it ensures that the horizontal movement of the adjusting component 31 is accurately converted into the displacement of the connecting rod 23, achieving precise adjustment of the driven wheel 22's position. When the second driving component 32 drives the adjusting component 31 to move horizontally, the first pushing surface 311a and the second pushing surface 231a press against each other. Due to the guiding effect of the inclined surfaces, the connecting part 231 drives the connecting rod 23 to move away from the driving wheel 21, and the driven wheel 22 moves synchronously. When the adjusting component 31 resets, the inclined surface engagement disengages, and the connecting rod 23, under the action of the subsequent buffer assembly 4, drives the driven wheel 22 to reset. This inclined pushing structure achieves precise conversion of the movement direction, improves the smoothness and accuracy of the adjustment action, reduces component wear, and extends the service life of the banknote feeding structure 10.

[0031] In one embodiment, please refer to Figures 2 to 5 The connecting part 231 has a conical structure, and the width of the connecting part 231 gradually increases along the direction close to the driven wheel 22.

[0032] The connecting part 231 is designed as a conical structure, integrally formed at both ends of the connecting rod 23. The axis of the cone coincides with the axis of the connecting rod 23, ensuring structural symmetry. The width of the connecting part 231 gradually increases towards the driven wheel 22, forming a conical structure that is narrower on the outside and wider on the inside. Its outer end face area is smaller, and its inner side smoothly transitions to the middle part of the connecting rod 23. The conical structure allows the second pushing surface 231a of the connecting part 231 to naturally form a slope, eliminating the need for additional complex slope structures, simplifying the processing technology, and reducing manufacturing costs. At the same time, the smooth conical surface reduces frictional resistance between the connecting part 231 and the pushing part 311 of the adjusting member 31, improving the smoothness of the adjustment action. The gradually changing width design of the connecting part 231 allows the thrust of the adjusting member 31 to be evenly transmitted to the connecting rod 23 along the conical surface, avoiding excessive local stress that could cause deformation of the connecting rod 23. It also ensures that the connecting rod 23 is balanced under force, driving the driven wheel 22 to move smoothly. When the adjusting member 31 pushes the connecting part 231, the guiding effect of the conical structure causes the connecting rod 23 to move in a preset direction without deviation or wobbling, ensuring the accuracy of the position adjustment of the driven wheel 22. Furthermore, the conical structure reduces the contact area between the connecting part 231 and the pushing part 311, thereby reducing the friction between them and helping to reduce wear on the connecting rod 23 and the adjusting member 31, thus improving their service life. In this embodiment, the pushing part 311 is a straight inclined surface structure facing the connecting part 231. In other embodiments, the pushing part 311 can also be configured as a concave arc-shaped inclined surface structure facing the connecting part 231. The concave arc shape adapts to the outer peripheral wall of the conical shape, also achieving the pushing effect on the connecting rod 23. The specific structure can be selected according to actual needs.

[0033] Furthermore, in one embodiment, please refer to Figures 2 to 4 The centering component 3 also includes a rolling element 33. Each adjusting element 31 has a mounting groove. The rolling element 33 is engaged in the mounting groove and is positioned facing the connecting part 231. The rolling element 33 is positioned in the extension direction of the first pushing surface 311a and is located on the side of the pushing part 311 away from the connecting part 231.

[0034] The centering component 3 also includes a rolling element 33, which can be a ball or a roller; in this embodiment, the rolling element 33 is a roller. The rolling element 33 possesses good wear resistance and rotational flexibility, reducing frictional resistance at the contact points. Each adjusting component 31 has a mounting groove machined on its pushing portion 311. The mounting groove is an arc-shaped recess, its size adapted to the rolling element 33. The rolling element 33 is engaged within the mounting groove, allowing it to roll freely within the groove without falling out. The rolling element 33 faces the connecting portion 231, its rolling direction is consistent with the extension direction of the first pushing surface 311a, and it is located on the side of the pushing portion 311 facing away from the connecting portion 231, forming a cooperative structure with the first pushing surface 311a. The rolling element 33 can convert the sliding friction between the adjusting component 31 and the connecting portion 231 into rolling friction, significantly reducing frictional resistance, preventing wear caused by long-term friction, and making the adjustment action smoother and reducing jamming. The rolling element 33 is arranged along the extension direction of the first pushing surface 311a. During the process of the adjusting element 31 pushing the connecting part 231, it rolls synchronously against the surface of the connecting part 231, assisting in guiding the adjustment direction and ensuring that the connecting part 231 moves the connecting rod 23 along a preset trajectory. When the adjusting element 31 moves horizontally, the first pushing surface 311a on the pushing part 311 and the second pushing surface 231a of the connecting part 231 are pressed together, and the rolling element 33 rolls synchronously, reducing friction damage and enhancing the stability of the adjustment action. When the adjusting element 31 resets, the rolling element 33 rolls in the opposite direction, assisting the adjusting element 31 in a smooth reset. The arrangement of the rolling element 33 further optimizes the cooperation between the adjusting element 31 and the connecting part 231, helping to improve the adjustment efficiency and service life of the centering component 3.

[0035] In one embodiment, please refer to Figure 2 and Figure 3 Both adjusting members 31 have a limiting groove 31a on the side facing the conveying channel, and the contact surface is located in the limiting groove 31a.

[0036] Both sets of adjusting components 31 have limiting grooves 31a machined on the side facing the conveying channel. These grooves 31a extend along the conveying channel and have a U-shaped structure with moderate depth, ensuring the banknote edge can be embedded without being excessively squeezed. The contact surface, which is the inner wall of the limiting groove 31a, is smoothed to reduce friction with the banknote edge, preventing scratches on the banknote surface. It also ensures that the contact surface applies a uniform pushing force, driving the banknote for centering adjustment. The limiting groove 31a provides lateral restraint for the banknote, allowing it to move along the channel's extension direction after the banknote edge is embedded, preventing vertical displacement during transport. Simultaneously, it concentrates the pushing force of the contact surface on the banknote edge, improving the efficiency of centering correction. When the adjusting components 31 approach each other, the contact surface of the limiting groove 31a conforms to the two edges of the banknote, pushing the banknote towards the center of the channel. Because the edges of the banknote are constrained by the limiting groove 31a, there will be no skewing caused by uneven local force, ensuring that the banknote can be accurately corrected to the center position of the channel. The integrated design of the limiting groove 31a and the contact surface not only strengthens the banknote's limiting effect and improves the accuracy of centering correction, but also protects the banknote from damage, further optimizing the performance of the banknote feeding structure 10.

[0037] In one embodiment, please refer to Figure 2 , Figure 3 as well as Figure 5 The banknote feeding structure 10 also includes a buffer assembly 4, which includes a mounting component 41, a top plate 42, and an elastic component 43. The mounting component 41 is connected to the side of the connecting rod 23 facing away from the drive wheel 21, the top plate 42 is fixedly connected to the mounting frame 1, and the two ends of the elastic component 43 abut against the mounting component 41 and the top plate 42 respectively in the axial direction.

[0038] The banknote feeding structure 10 also includes a buffer assembly 4, which comprises a mounting component 41, a top plate 42, and an elastic element 43. These three components work together to provide the connecting rod 23 with restoring elasticity and buffer protection. The mounting component 41 is fixedly connected to the side of the connecting rod 23 facing away from the drive wheel 21 by bolts or screws. Its structure is adapted to the connecting rod 23 and can move synchronously with it, providing a stable force-bearing carrier for the elastic element 43. The top plate 42 is fixedly connected to the mounting frame 1 by bolts or screws, and its position is fixed, serving as a fixed support end for the elastic element 43, ensuring that the elastic element 43 can stably store and release elastic potential energy. The elastic element 43 is a compression spring, which can be made of high-strength spring steel and can withstand long-term repeated compression deformation without failure. Its axial ends abut against the mounting component 41 and the top plate 42 respectively, always in a pre-compressed state. The buffer assembly 4 provides the restoring force for the connecting rod 23. When the adjusting component 31 returns to its original position, the elastic restoring force of the elastic element 43 pushes the mounting component 41 towards the drive wheel 21. The mounting component 41 drives the connecting rod 23 and the driven wheel 22 to reset synchronously, restoring the initial distance with the drive wheel 21 and ensuring stable clamping and conveying of subsequent banknotes. Simultaneously, the elastic element 43 buffers the thrust of the adjusting component 31 on the connecting rod 23, preventing excessively violent adjustment movements that could damage components and reducing equipment operating noise. When the adjusting component 31 pushes the connecting rod 23 to a position, the mounting component 41 squeezes the elastic element 43, causing the elastic element 43 to contract and store potential energy, buffering the thrust. After the adjusting component 31 resets, the elastic element 43 releases its potential energy, causing the connecting rod 23 to reset smoothly. The buffer assembly 4 enables automatic reset and buffer protection of the connecting rod 23, improving the smoothness and reliability of the banknote feeding structure 10's operation.

[0039] Furthermore, in one embodiment, please refer to Figure 2 and Figure 5 The mounting component 41 extends along the side opposite to the drive wheel 21 and forms a guide post 411 and a guide groove 41a. The elastic member 43 is sleeved on the guide post 411 and the outer peripheral wall of the elastic member 43 is engaged in the guide groove 41a.

[0040] Mounting member 41 extends integrally along the side opposite to the drive wheel 21, forming a guide post 411 and a guide groove 41a. The guide post 411 is a cylindrical structure, coaxially arranged with the axis of mounting member 41, and is used to provide installation guidance for elastic member 43. The guide groove 41a is an annular groove, formed on the surface of mounting member 41 outside the guide post 411. The groove width matches the diameter of elastic member 43, and the depth is moderate. Elastic member 43 is sleeved on the outside of guide post 411, ensuring that elastic member 43 can extend and retract along the axial direction of guide post 411, avoiding displacement or skew during compression or reset, and ensuring stable transmission of elastic force. The outer peripheral wall of elastic member 43 is engaged in guide groove 41a, which acts as a radial limit for elastic member 43, further preventing deformation or displacement of elastic member 43, and ensuring that elastic member 43 is always in the preset working position. The cooperation between the guide post 411 and the guide groove 41a provides precise installation positioning and motion guidance for the elastic element 43, making the extension and retraction of the elastic element 43 smoother. The elastic force can be evenly applied to the mounting part 41, driving the connecting rod 23 to move and return smoothly. At the same time, this structure can reduce friction and wear between the elastic element 43 and the mounting part 41 and the top plate 42, extending the service life of the elastic element 43. During assembly, the elastic element 43 is fitted onto the guide post 411, and then the outer peripheral wall of the elastic element 43 is inserted into the guide groove 41a to ensure that the elastic element 43 is firmly installed and subsequent actions are stable and reliable.

[0041] In one embodiment, please refer to Figure 2 and Figure 3 The central component 3 also includes a transmission mechanism 34, which includes a transmission worm 341 and a mounting rod 342. The mounting rod 342 is connected to the mounting frame 1. Two adjusting members 31 are respectively sleeved on both ends of the mounting rod 342 in the axial direction and can slide back and forth along the axial direction of the mounting rod 342. The transmission worm 341 is connected to the output end of the second driving member 32. The two ends of the transmission worm 341 in the axial direction are provided with helical teeth with opposite directions of rotation. One adjusting member 31 is correspondingly engaged with the helical teeth.

[0042] The central component 3 also includes a transmission mechanism 34, which comprises a transmission worm 341 and a mounting rod 342. This mechanism transmits power between the second driving component 32 and the two sets of adjusting components 31, ensuring that the adjusting components 31 move synchronously in opposite directions. The axis of the mounting rod 342 is parallel to the width direction of the conveying channel and is fixedly connected to the mounting frame 1 via a bracket, maintaining a fixed position. The two sets of adjusting components 31 are respectively fitted onto the two ends of the mounting rod 342 along its axial direction, achieving reciprocating sliding along the axial direction of the mounting rod 342 through sliding engagement. The mounting rod 342 provides precise motion guidance for the two sets of adjusting components 31. The transmission worm 341 is made of metal with helical teeth machined on its surface. It is mounted to the mounting frame 1 via bearings, with one end fixedly connected to the output end of the second driving component 32, receiving driving force to achieve rotation. The two ends of the transmission worm 341 along its axial direction have helical teeth with opposite directions of rotation. The two sets of adjusting components 31 mesh with the corresponding helical teeth, ensuring that when the transmission worm 341 rotates, the two sets of adjusting components 31 move synchronously in opposite directions. The transmission mechanism 34 converts the rotational power of the second driving member 32 into the linear motion of the adjusting member 31. The design of the helical teeth with opposite rotation directions allows a single drive source to achieve the opposite or backward movement of the two sets of adjusting members 31, simplifying the structural layout and reducing manufacturing costs. After the second driving member 32 is activated, it drives the transmission worm gear 341 to rotate through the gear transmission structure. Because the helical teeth rotate in opposite directions, the two sets of adjusting members 31 synchronously move closer or further away along the mounting rod 342, achieving the centering correction or reset of the banknote. The mounting rod 342 ensures the precise movement trajectory of the adjusting member 31, avoiding deviation and improving the stability of the adjustment action. This transmission mechanism 34 design has high transmission accuracy and good action synchronization, further improving the adjustment accuracy and reliability of the centering component 3. In other embodiments, two second driving members 32 can also be used to drive the two adjusting members 31 respectively, causing the two adjusting members 31 to synchronously generate opposite or backward movements; the specific choice can be made according to actual needs.

[0043] This invention also proposes a banknote reader 100, which includes a banknote feeding structure 10 and a housing 20. The housing 20 has an installation cavity and a banknote inlet 201. The banknote feeding structure 10 is installed in the installation cavity, and a conveying channel is provided corresponding to the banknote inlet 201. The specific structure of the banknote feeding structure 10 is as described in the above embodiments. Since this banknote reader 100 adopts all the technical solutions of all the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here. Please refer to... Figure 6The banknote reader 100 provides a closed installation space and protection through the housing 20. The banknote feeding structure 10 facilitates the smooth feeding and centering of banknotes, providing standardized banknotes for subsequent counting, recognition, and sorting processes. The housing 20 can be made of high-strength plastic or metal, with a robust structure and good dustproof and impact-resistant properties. It forms a sealed installation cavity, providing installation space for the banknote feeding structure 10 and other components while protecting internal components from external contamination and damage. A banknote feeding port 201 is located on one side of the housing 20. The banknote feeding port 201 has a rectangular structure, its width adapted to the conveyor channel, and rounded edges to avoid scratching banknotes and facilitate user insertion. The banknote feeding structure 10 is installed entirely within the installation cavity. The mounting bracket 1 is fixed to the inner wall of the installation cavity using bolts and other fasteners, ensuring that the banknote feeding structure 10 does not shift during operation. The conveyor channel is precisely aligned with the banknote feeding port 201, allowing banknotes inserted through the banknote feeding port 201 to directly enter the conveyor channel for smooth transport. The housing 20 provides a stable mounting base and comprehensive protection for the banknote feeding structure 10, preventing external interference from affecting its operation. Simultaneously, the precise alignment of the banknote inlet 201 with the conveying channel ensures that banknotes can smoothly enter the conveying system. After the user places banknotes into the inlet 201, the conveying component 2 of the banknote feeding structure 10 carries the banknotes into the conveying channel, and the centering component 3 quickly corrects the banknote position, ensuring that the banknotes are conveyed along the center of the channel to subsequent processes. The integrated design of the banknote machine 100 achieves the integration of banknote feeding, conveying, and centering correction, resulting in a compact structure, reliable operation, and effectively improving the banknote processing efficiency and stability of the banknote machine 100.
