Description

Technical Field

[0001] This utility model relates to the field of banknote counting machines, and more particularly to an easy-to-maintain banknote counting machine for self-service payment machines. Background Technology

[0002] In self-service equipment in the fields of finance, transportation, and healthcare, banknote counters are the core cash processing module. Their stability and maintainability directly affect the overall operating efficiency of the equipment. Their core function is to insert banknotes from the banknote outlet, and then, under the action of various drive wheels, pass through the banknote passage and be taken out from the banknote outlet. The counting or identification of authenticity is achieved by sensors installed in the banknote counter. However, during long-term use, dust and paper scraps are prone to accumulate in the banknote passage or banknote jamming may occur. Therefore, regular maintenance and cleaning are required.

[0003] However, because the banknote passage is located deep inside the device and is enclosed by the outer casing and fixed plate, it is difficult for operators to directly observe and touch it. In addition, operating in such a small space requires long and thin cleaning tools to be inserted, which can easily cause accidental contact with internal sensors and rollers and damage them.

[0004] Therefore, how to conveniently and quickly open the banknote passage to access its internal structure and thus facilitate the cleaning and maintenance of the banknote passage of the banknote counter has become an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an easy-to-maintain banknote counter for self-service payment machines, which allows access to the first through plate for cleaning and maintenance by rotating the mounting base to release the latch and limit post.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a frame, a left mounting portion located on the left side of the frame, and a right mounting portion located on the right side of the frame. The frame has a banknote inlet plate at the top, a banknote outlet plate at the bottom, and a banknote passage between the inlet and outlet plates. It also includes a wheel assembly for moving banknotes and a drive module for driving the wheel assembly. A first tension spring is also included. The frame includes a top mounting base and a base below the mounting base. The base includes a first passage plate below the banknote passage. The right mounting portion includes a first... The first mounting plate and the second mounting plate are located to the right of the first mounting plate and are detachably connected to the first mounting plate. The mounting base is rotatably mounted on the base. The first mounting plate is provided with latches on both the left and right sides. The base is provided with limiting posts that cooperate with the latches on the rotation trajectory of each latch. Each limiting post extends horizontally and the latch is provided with a mounting groove for the limiting post to be inserted. One end of each first tension spring is connected to the second mounting plate on the corresponding side and the other end is connected to the corresponding latch. The base is provided with an insertion groove above the limiting post for the latch to be rotated and inserted.

[0007] The present invention is further configured such that: a contact groove is provided on the front side of the base and the base is located below the contact groove, and the base is located in front of the contact groove and is open.

[0008] The present invention is further configured such that: each of the latches also includes a first guide surface and a second guide surface located on the upper and lower sides of the mounting groove, the second guide surface being inclined from front to back and from bottom to top, and each of the latches also includes a mating surface on the bottom front side, the mating surface being inclined from front to back and from top to bottom.

[0009] The present invention is further configured to include: a rotating shaft located on the mounting base and inserted on the left and right sides of the base, and a torsion spring sleeved on both sides of the rotating shaft, with one end of each torsion spring connected to the first mounting plate and the other end connected to the base.

[0010] The present invention is further configured as follows: it also includes a second tension spring; a disassembly plate is rotatably mounted on the rear side of the base; a second passage plate is provided on the disassembly plate above the banknote passage; mating posts are protruding on both the left and right sides of the disassembly plate; a track groove for the mating posts to rotate is provided on the first mounting plate; mating hooks are installed on both the left and right sides of the second passage plate; and a positioning post is provided on each of the first mounting plates so that the rear end face of each mating hook abuts against the front side of the corresponding positioning post; one end of the second tension spring is connected to the mating hook and the other end is connected to the disassembly plate.

[0011] The present invention is further provided with a wrench on the rear side of the disassembly plate.

[0012] This utility model is further configured such that: the wheel set includes a mating wheel, a first rotating wheel, a second rotating wheel, a third rotating wheel, a fourth rotating wheel, a fifth rotating wheel, a sixth rotating wheel, a seventh rotating wheel, an eighth rotating wheel, a ninth rotating wheel, a tenth rotating wheel, an eleventh rotating wheel, a twelfth rotating wheel, a thirteenth rotating wheel, a fourteenth rotating wheel, a fifteenth rotating wheel, a sixteenth rotating wheel, a seventeenth rotating wheel, an eighteenth rotating wheel, and a nineteenth rotating wheel, all located on a first mounting plate; the drive module includes a mating wheel... A fixed drive motor, a first synchronous belt for transmission between the mating pulley, the first rotating pulley and the second rotating pulley, a second synchronous belt for transmission between the third rotating pulley and the fifth rotating pulley, a third synchronous belt for transmission between the fourth rotating pulley, the sixth rotating pulley, the eighth rotating pulley and the thirteenth rotating pulley, a fourth synchronous belt for transmission between the seventh rotating pulley and the ninth rotating pulley, a fifth synchronous belt for transmission between the tenth rotating pulley, the nineteenth rotating pulley and the eighteenth rotating pulley, a sixth synchronous belt for transmission between the twelfth rotating pulley and the seventeenth rotating pulley, and a seventh synchronous belt for transmission between the fourteenth rotating pulley, the fifteenth rotating pulley and the sixteenth rotating pulley.

[0013] By adopting the above technical solution, 1. By applying an upward and backward force to the mounting base, the latch can overcome the force of the first tension spring and move upward and backward, thus separating the mounting groove from the limiting post and unlocking the device. When the mounting base is rotated downward and forward, the latch can pass over the limiting post as it moves towards the limiting post, thus achieving the engagement between the mounting groove and the limiting post. This ensures that the latch will not separate from the limiting post without external force, and the elastic force of the first tension spring further improves the stability of the connection between the two, effectively preventing the latch from loosening due to vibration during equipment operation; 2. After separating the latch from the limiting post, the mounting base rotates relative to the base, causing the mounting base side of the banknote passage to separate from the base side, opening the banknote passage. This exposes the internal wheel assembly, sensors, and other components, enabling cleaning, maintenance, and handling of jammed banknotes in the banknote passage. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1-8 As shown, this utility model discloses an easy-to-maintain banknote counting machine for self-service payment machines, including a frame 1 with buttons (not shown) on the front, a left mounting part 2 on the left side of the frame 1, and a right mounting part 3 on the right side of the frame 1. The frame 1 has a banknote inlet plate 4 at the top and a banknote outlet plate 5 at the bottom. A banknote passage 6 is provided between the banknote inlet plate 4 and the banknote outlet plate 5. It also includes a wheel set for moving banknotes and a drive module for driving the wheel set. By activating the drive module to rotate the wheel set, banknotes inserted from the banknote inlet plate 4 are conveyed through the rotation of the wheels within the wheel set. During this conveying process, the banknotes are used for counting or identification. The sensor that detects the authenticity of the paper money falls into the banknote dispensing plate 5 after contacting the panel (this is existing technology and will not be described in detail here). It also includes a first tension spring 7. The frame 1 includes a top mounting base 8 and a base 9 located below the mounting base 8. The base 9 includes a first passage plate 10 located below the banknote passage 6. The right mounting part 3 includes a first mounting plate 11 and a second mounting plate 12. The second mounting plate 12 is located to the right of the first mounting plate 11 and is detachably connected to it. The mounting base 8 is rotatably mounted on the base 9. The first mounting plate 11 has latches 13 on both its left and right sides, and the base 9 is positioned along the rotation path of each latch 13. The latch 13 is fitted with a limiting post 14. Each limiting post 14 extends horizontally, and the latch 13 is provided with a mounting groove 15 for inserting the limiting post 14. One end of each first tension spring 7 is connected to the second mounting plate 12 on the corresponding side, and the other end is connected to the corresponding latch 13. The base 9 is located above the limiting post 14 and is provided with an insertion groove 16 for the latch 13 to rotate into. 1. By applying an upward and backward force to the mounting base 8, the latch 13 can overcome the force of the first tension spring 7 and move upward and backward, causing the mounting groove 15 to separate from the limiting post 14, thereby unlocking. When the mounting base 8 is rotated downward and forward, the latch 13 moves towards the limiting post 14. During the process, the mounting slot 15 can pass over the limiting post 14, thereby achieving the cooperation between the mounting slot 15 and the limiting post 14. This ensures that the latch 13 will not separate from the limiting post 14 without external force. Under the elastic force of the first tension spring 7, the stability of the connection between the two can be further improved, effectively preventing the latch 13 from loosening due to vibration during equipment operation. 2. After the latch 13 and the limiting post 14 are separated, the mounting seat 8 rotates relative to the base 9, which allows the mounting seat 8 side of the banknote passage 6 to separate from the base 9 side, thus opening the banknote passage 6. This exposes the internal wheel assembly, sensors, and other components, enabling the cleaning, maintenance, and handling of jammed banknotes in the banknote passage 6.

[0019] The base 9 has a contact groove 17 on its front side and is located below the contact groove 17. The base 9 is open on the front side of the contact groove 17, so that when it is necessary for the mounting seat 8 and the base 9 to rotate relative to each other, the mounting seat 8 can be rotated by inserting into the contact groove 17 and applying force to the bottom of the mounting seat 8 to open the banknote passage 6.

[0020] Preferably, each of the latches 13 further includes a first guide surface 18 and a second guide surface 19 located on the upper and lower sides of the mounting groove 15. The second guide surface 19 is inclined from front to back and from bottom to top. Each of the latches 13 also includes a mating surface 20 on the front bottom side. The mating surface 20 is inclined from front to back and from top to bottom. After cleaning and maintenance, rotating the mounting base 8 downwards will allow the bottom of the latch, i.e., the mating surface 20, to first contact the circumference of the limiting post 14. The limiting post 14 and the mating surface 20 will then contact and interact, allowing the limiting post 14 to pass over the mating surface 20. As the mounting base 8 continues to rotate downwards, the mounting groove 15 engages with the limiting post 14. When the limiting post 14 slides past the highest point of the second guide surface 19, the elastic force of the first tension spring 7 drives the latch 13 to reset inwards, so that the mounting groove 15 is stably engaged with the limiting post 14, thus locking it. When unlocking is required without external force, the mounting base 8 is pulled backwards and upwards, which pulls the second mounting plate 12. This pulling force is transmitted to the latch 13, which drives the latch 13 to overcome resistance and move outwards, so that the mounting groove 15 disengages from the limiting post 14, thereby releasing the lock on the mounting base 8.

[0021] Preferably, the mounting base 8 also includes rotating shafts 21 located on the mounting base 8 and inserted on both sides of the base 9, and torsion springs 22 sleeved on both sides of the rotating shafts 21. One end of each torsion spring 22 is connected to the first mounting plate 11 and the other end is connected to the base 9. When the mounting base 8 is closed, the torsion springs 22 are in a free state or a slightly pre-compressed state. At this time, when the user pulls the mounting base 8, the latch 13 disengages from the limiting post 14, releasing the locking relationship. At this time, the elastic potential energy stored in the torsion springs 22 begins to be released. This torque can be converted into an upward thrust on the mounting base 8, improving the ease of operation. When the mounting base 8 is closed... After rotating upwards to the maximum position, the torsion spring 22 is at its maximum deformation, storing the most elastic potential energy. This elastic potential energy is close to the weight of the mounting base 8, allowing the mounting base 8 to remain stably in the open position without sagging due to gravity, thus facilitating the cleaning of the banknote passage 6. When the mounting base is pressed downwards to begin closing, since the free state of the torsion spring 22 is the fully closed position of the mounting base 8, the torque of the torsion spring 22 also pushes the mounting base downwards during the downward movement of the mounting base 8, making the closing of the mounting base 8 easier.

[0022] The system also includes a second tension spring 23. A disassembly plate 24 is rotatably mounted on the rear side of the base 9. A second passage plate 25 located above the banknote passage 6 is provided on the disassembly plate 24. Matching posts 2926 protrude from both the left and right sides of the disassembly plate 24. A track groove 27 for the rotation of the matching posts 2926 is provided on the first mounting plate 11. Matching hooks 28 are installed on both the left and right sides of the second passage plate 25, and each first mounting plate 11 is provided with a positioning post 63 so that the rear end face of each matching hook 28 abuts against the front side of the corresponding positioning post 63. One end of the second tension spring 23 is connected to the matching hook 28, and the other end is connected to the disassembly plate 24. Because the disassembly plate 24 is rotatably mounted... The addition of the rotating design of the disassembly plate 24 to the frame 1 allows the second passage plate 25 to be rotated downwards to open the rear side of the banknote passage 6, in addition to rotating the mounting base 8 upwards. This further facilitates the cleaning and maintenance of the banknote passage 6. Furthermore, the rotation of the disassembly plate 24 and the mounting base 8 are independent, allowing the user to choose to rotate the mounting base 8 or the disassembly plate 24, or both, according to their needs, making maintenance more flexible. In addition, the cooperation between the hook 28 and the cooperating column 2926, combined with the stretching and resetting of the second tension spring 23, forms a locking mechanism, which ensures that the disassembly plate 24 can stably close the rear side of the frame 1 after being rotated forward.

[0023] A wrench 30 is provided on the rear side of the disassembly plate 24. The wrench 30 provides the user with a convenient and labor-saving point of force application for pulling or pushing the disassembly plate 24 to perform opening and closing operations.

[0024] The wheel assembly includes a mating wheel 31, a first rotating wheel 32, a second rotating wheel 33, a third rotating wheel 34, a fourth rotating wheel 35, a fifth rotating wheel 36, a sixth rotating wheel 37, a seventh rotating wheel 38, an eighth rotating wheel 39, a ninth rotating wheel 40, a tenth rotating wheel 41, an eleventh rotating wheel 42, a twelfth rotating wheel 43, a thirteenth rotating wheel 44, a fourteenth rotating wheel 45, a fifteenth rotating wheel 46, a sixteenth rotating wheel 47, a seventeenth rotating wheel 48, an eighteenth rotating wheel 49, and a nineteenth rotating wheel 50, all located on the first mounting plate 11. The three rotating wheels 34 are coaxially arranged; the fourth rotating wheel 35 and the fifth rotating wheel 36 are coaxially arranged; the seventh rotating wheel 38 and the eighth rotating wheel 39 are coaxially arranged; the ninth rotating wheel 40 and the tenth rotating wheel 41 are coaxially arranged; the eleventh rotating wheel 42 and the twelfth rotating wheel 43 are coaxially arranged; and the fourteenth rotating wheel 45 and the thirteenth rotating wheel 44 are coaxially arranged. The drive module includes a drive motor 51 fixed to the mating wheel 31; a first synchronous belt 52 for transmission between the mating wheel 31, the first rotating wheel 32 and the second rotating wheel 33; a second synchronous belt 53 for transmission between the third rotating wheel 34 and the fifth rotating wheel 36; a third synchronous belt 54 for transmission between the fourth rotating wheel 35, the sixth rotating wheel 37, the eighth rotating wheel 39 and the thirteenth rotating wheel 44; and a transmission belt 54 for transmission between the seventh rotating wheel. The fourth synchronous belt 55 between the 38th and the ninth rotating wheel 40, the fifth synchronous belt 56 between the tenth rotating wheel 41, the nineteenth rotating wheel 50, and the eighteenth rotating wheel 49, the sixth synchronous belt 57 between the twelfth rotating wheel 43 and the seventeenth rotating wheel 48, and the seventh synchronous belt 58 between the fourteenth rotating wheel 45, the fifteenth rotating wheel 46, and the sixteenth rotating wheel 47, when the banknote counter is started, pressing the button allows the signal to be transmitted to the drive motor 51, causing the output shaft of the drive motor 51 to drive the mating wheel 31 to rotate. After the mating wheel 31 rotates, it can drive the first synchronous belt 52 to transmit torque to the first rotating wheel 32 and the second rotating wheel 33. At this time, since the second rotating wheel 33 and the third rotating wheel 34 are coaxially arranged... Therefore, the synchronously rotating third wheel 34 transmits torque to the fifth wheel 36 via the second synchronous belt 53. Since the fifth wheel 36 and the fourth wheel 35 are coaxially arranged, the synchronous rotation of the fourth wheel 35 can transmit torque to the sixth wheel 37, the eighth wheel 39, and the thirteenth wheel 44 via the third synchronous belt 54. The thirteenth wheel 44 and the fourteenth wheel 45 are coaxial, allowing the fourteenth wheel 45 to transmit torque to the seventh synchronous belt 58, which in turn drives the fifteenth wheel 46 and the sixteenth wheel 47 to rotate. Furthermore, since the eighth wheel 39 and the seventh wheel 38 are coaxially arranged, the seventh wheel 38 can transmit torque to the ninth wheel 40 via the fourth synchronous belt 55. Since the ninth wheel 40 and the tenth wheel 41 are coaxially arranged...Therefore, the synchronously rotating tenth pulley 41 can transmit torque to the fifth synchronous belt 56, causing the nineteenth pulley 50 and the eighteenth pulley 49 to rotate. Since the eleventh pulley 42 is located above and in direct contact with the fifth synchronous belt 56, the movable fifth synchronous belt 56 can drive the eleventh pulley 42 to rotate, thereby enabling the coaxially arranged eleventh pulley 42 to drive the twelfth synchronous pulley to rotate, thus transmitting torque to the sixth synchronous belt 57 and the seventeenth pulley 48. In addition, a cooperating motor 60 is connected to the nineteenth pulley 50, and the output shaft of the cooperating motor 60 is fixed to the nineteenth pulley 50. The sixth and ninth pulleys are located inside the base 9, and a rotatable switching component 59 is provided inside the bracket to... The banknote passage 6 is divided into a first branch 61 and a second branch 62 on its front side. The first branch 61 is connected to the banknote output plate 5, while the second branch 62 extends downward through the base 9. When the changing mechanism 59 is rotated to connect the banknote passage 6 with the second branch 62, the banknotes can be moved downward from the second branch 62 during the high-speed rotation of the seventeenth rotating wheel 48. During normal operation, the drive motor 51 plays a leading role in driving the drive module. A one-way clutch is provided between the ninth rotating wheel 40 and the tenth rotating wheel 41 on the frame 1. This allows the drive motor 60 to be activated when the banknotes in the second branch 62 on the base 9 are to be output downward after the drive motor 51 stops.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
