When the second banknote feeding motor 272 is activated, it can drive the second banknote feeding motor shaft 2721 to rotate, thereby driving the second synchronous belt 562 to operate. The third timing belt 563 passes through the second bill-feeding motor shaft 2721, the third intermediate shaft 454, the first transfer shaft 431, the second intermediate shaft 434, the second transfer shaft 432, the first transfer shaft 433, the first intermediate shaft 455, and the first channel belt shaft 441, forming a belt drive mechanism. When the second bill-feeding motor shaft 2721 rotates, it drives the second timing belt 562 and the third timing belt 563, respectively, thereby driving the second bill-feeding shaft 422, the second bill-feeding motor shaft 2721, the first channel belt shaft 441, the second intermediate shaft 455, the third transfer shaft 433, the second transfer shaft 432, the second intermediate shaft 434, and the first transfer shaft 431 to rotate in a circular motion, thereby conveying banknotes.

[0058] In the initial state, the diverter plate 610 connects the third channel with the first channel and closes the second channel. If a banknote passes inspection, it is fed into the third channel 03 and then stacked on the banknote receiving platform 340 by the banknote receiving wheel 554. If a banknote in the first channel fails inspection, the diverter plate 610 closes the third channel, connects the first channel with the second channel, and the banknote is fed into the second channel and then stored on the banknote return plate 310.

[0059] Preferably, the banknote turning wheel shaft 410 is also provided with a first coding disk 411 , and the edge of the first coding disk 411 is installed in the first encoder 223 , so that the first encoder 223 cooperates with the first coding disk 411 to detect the rotation speed and rotation angle of the banknote turning wheel shaft 410 .

[0060] Preferably, the second money feeding shaft 422 is provided with a second encoding disc 4221 , and the edge of the second encoding disc 4221 is installed in the second encoder 224 , so that the second encoder 224 cooperates with the second encoding disc 4221 to detect the rotation speed and rotation angle of the second money feeding shaft 422 .

[0061] Preferably, a reversing detection piece 461 is mounted on the reversing shaft 460. The reversing detection piece 461 can be installed in the reversing sensor 227, thereby causing the reversing sensor 227 to send a signal to the industrial computer, indicating that the second channel is connected to the first channel. In the initial state, the reversing detection piece 461 is not installed in the reversing sensor 227, and the first channel and the third channel are connected.

[0062] Since the number of inspected banknotes is generally large, leaving them exposed poses a safety hazard. Furthermore, inspected banknotes can be directly deposited into banknote bags (after counting and denomination accumulation) when needed. If the banknotes on the receiving platform are not protected, operators may remove some banknotes before depositing them into the banknote bags, potentially leading to disputes. Therefore, a protective cover mechanism has been designed. The protective cover 320 of the protective cover mechanism encloses the banknote receiving platform 340 within the sorting module 120 to avoid this problem.

[0063] The protective cover mechanism includes a protective cover 320, and the two sides of the protective cover 320 are respectively hinged to the first cleaning side plate 123 and the second cleaning side plate 124 through the protective cover shaft 409, wherein one protective cover shaft 409 passes through the first cleaning baffle 123 and is assembled and fixed with the induction plate 710, and the protective cover shaft 409 is assembled and fixed with the protective cover, and the induction plate 710 is installed with a first power pin 405, and the first power pin 405 is engaged with the guide arc groove 103 provided on the first cleaning baffle 123 and can be slidably assembled; a first power pin 405 is installed on one side of the induction plate 710. The first power rod 720 is provided with a sensing edge 711 on the other side. The sensing edge 711 can be selectively installed in the first sensor 221 or the second sensor 222. The first sensor 221 and the second sensor 222 are installed on the two maximum displacement points of the sensing plate 710 rotating around the protective cover axis 409; in the initial state, the sensing edge 711 is installed in the first sensor 221. At this time, the top of the protective cover 320 is tightly attached to the connecting plate 126, and the bottom enters the inner side of the clearing front block 122, thereby closing the banknote receiving platform 340.

[0064] The first power rod 720 is provided with a first rod slide groove 721, the first rod slide groove 721 is engaged with the second power pin 406 and can be slidably assembled, the second power pin 406 is installed on the second power rod 730, the second power rod 730 is provided with a second rod slide groove 731 and its end away from the second power pin 406 is hinged to the first clearing baffle 123 through the rod rotating shaft 408; the second rod slide groove 731 is engaged with the third power pin 407 and can be slidably assembled, the third power pin 407 is eccentrically (not coaxial with the power disk) installed on the power disk 740, and the power disk 740 is installed on the motor shaft of the protective cover motor 274. When the protective cover 320 needs to be opened, the protective cover motor 274 is activated, driving the power disk 740 to rotate in a circular motion. The power disk 740, via the third power pin 407, drives the second power rod 730 to rotate about the rod shaft 408. The second power rod 730, via the second power pin 406, drives the sensing plate 710 to rotate about the protective cover axis 409, thereby driving the synchronous rotation of the protective cover 320. During this process, the first power pin 405 cooperates with the guide arc groove 103 to improve the rotational stability of the sensing plate 710. When the protective cover is fully opened, the banknote receiving platform is exposed, and the sensing edge 711 is now assembled with the second sensor 222. The first sensor 221 and the second sensor 222 are photoelectric sensors. When the sensing edge 711 is installed, an electrical signal is generated, which is then input into the industrial computer, allowing the industrial computer to determine the current position of the protective cover.

[0065] Preferably, in order to prevent the protective cover from being violently opened, the present embodiment is further provided with an electromagnet 240 at the first clearing side plate 123 and the second clearing side plate 124, respectively. The telescopic shaft 241 of the electromagnet 240 passes through the first clearing side plate 123 or the second clearing side plate 124 and enters the inner side of the protective cover 320, so that the protective cover 320 cannot be rotated downward, and the top of the protective cover 320 is restricted by the connecting plate 126 and cannot be rotated upward, thereby preventing the protective cover 320 from being opened unnecessarily and violently. When the protective cover needs to be opened, the electromagnet 240 is first started so that the telescopic shaft of the electromagnet 240 retracts to a position where it does not interfere with the rotation of the protective cover, and then the protective cover motor 274 is started to drive the protective cover to rotate and open with the protective cover shaft as the center. When the protective cover needs to be closed, the protective cover motor is reversed to drive the protective cover to reset, and then the electromagnet drives the telescopic shaft to extend and reset.

[0066] Since the banknotes after sorting need to be temporarily stored on the banknote receiving platform 340, and after the deposit is confirmed, the banknotes need to be separated from the banknote receiving platform 340 and then dropped into the banknote bag of the banknote bag module for storage, it is necessary to set the banknote receiving platform 340 in a rotatable manner to release the banknotes. This embodiment realizes this function through the banknote receiving platform flipping mechanism.

[0067] The banknote receiving platform flipping mechanism includes a banknote receiving platform 340, a banknote receiving front stop 330, and a banknote receiving side stop 341. The two sides of the banknote receiving front stop 330 are respectively assembled with the banknote receiving side stops 341, and the banknote receiving side stops 341 are installed on the first sorting side plate 123 or the second sorting side plate 124 close thereto; the end of the banknote receiving platform 340 away from the banknote receiving front stop 330 is hinged to the banknote receiving side stop 341 through the banknote receiving shaft 404; the banknote receiving shaft 404 is provided with a banknote receiving torsion spring 640, and the two ends of the banknote receiving torsion spring 640 are respectively assembled with the banknote receiving platform 340 and the banknote receiving front stop 341 to apply a torque to the banknote receiving platform 340 to rotate the banknote receiving front stop 341, so that the banknote receiving platform 340 remains in close contact with the banknote receiving front stop 341. The banknote receiving front stop 341 is further provided with a mounting hole 3411 , through which a screw is passed to assemble with the banknote receiving front stop 330 , and the telescopic shaft 241 of the electromagnet 240 is preferably pressed or inserted into the mounting hole 3411 of the banknote receiving front stop 341 , thereby greatly improving the locking force of the protective cover 320 .

[0068] A banknote receiving platform 340 is provided with a hinged base 342 at its bottom. This hinged base 342 is hingedly connected to one end of a banknote receiving link 343. The other end of the banknote receiving link 343 is hingedly connected to a lever plate 650 via a pin 660. A second gear 572 is mounted on the pin 660. The second gear 572 meshes with a first gear 571 for transmission. The first gear 571 is mounted on a tilting motor shaft 2751. The tilting motor shaft 2751 is mounted within the tilting motor 275. When the tilting motor 275 is activated, it drives the tilting motor shaft 2751 to rotate in a circular motion, thereby causing the lever plate 650 to rotate about the tilting motor shaft 2751. Rotation of the lever plate 650 drives the banknote receiving platform 340 downwardly through the banknote receiving link 343, causing the platform to rotate downward to eject banknotes or upward to reset itself. This rotation of the banknote receiving platform also drives the banknote receiving shaft 404 to rotate synchronously.

[0069] Preferably, a banknote receiving detection piece 4041 is provided on the banknote receiving shaft 404. The banknote receiving detection piece 4041 is selectively installed in the first banknote receiving sensor 225 or the second banknote receiving sensor 226. When the banknote receiving platform 340 is in close contact with the banknote receiving side stop 341, the banknote receiving detection piece 4041 is installed in the second banknote receiving sensor 226, at which point it is determined that the banknote receiving platform 340 is receiving banknotes normally. After the banknote receiving platform 340 rotates downward to its full position, the banknote receiving detection piece 4041 is installed in the first banknote receiving sensor 225, at which point it is determined that the banknote receiving platform 340 has completed banknote ejection. The first banknote receiving sensor 225 and the second banknote receiving sensor 226 can be photoelectric sensors. When the banknote receiving detection piece 4041 is installed, an electrical signal is generated and input to the industrial computer, which determines the position of the banknote receiving platform based on the signal.

[0070] See also Figure 1-Figure 5 , Figure 30-40The banknote bag module includes a banknote bag A210, a banknote bag fixing frame A220, a safety door box A230, and a protection door frame A240. The banknote bag A210 is used to store banknotes and has an open top; the banknote bag fixing frame A220 includes a fixing frame A222 and a pressure strip A221. The top opening of the banknote bag A210 is mounted on the fixing frame A222, and the pressure strip A221 is assembled and fixed to the fixing frame A222 by screws, thereby pressing the banknote bag A210 against the fixing frame A222 to fix the banknote bag. One side of the fixed frame A222 is hinged to one side of the safety door box A230 through a hinge A610, and a lock frame A235 is installed on the other side of the safety door box A230. Lock plates A223 are installed at the corresponding positions of the fixed frame A222 and the lock frame A235. A lock slot A2231 is provided on the lock plate A223, and the lock slot A2231 is engaged with the lock hook plate A713 and can be slidably assembled. One end of the lock hook plate A713 is installed on the lock hook part A710, and a lock hook A711 is provided on the other end. The lock hook A711 is hooked at the edge of the lock slot A2231, so that the lock hook part and the lock plate are relatively fixed. The lock hook part A710 is also provided with a lock hook part limiting plate A714 and a lock hook part sliding groove A712, respectively. The lock hook part sliding groove A712 is engaged with the lock hook part pin A720 and can be slidably assembled.

One end of the lock hook A710 is assembled with one end of the second locking spring A530, and the other end of the second locking spring A530 is assembled with the lock frame A235, so that the lock hook A710 is pressed against the edge of the lock slot A2231 by the elastic force of the second locking spring A530 to keep the lock hook A711 clamped against the edge of the lock slot A2231. One end of the lock hook drive plate A730 is assembled with one end of the first locking spring A520, and the other end of the first locking spring A520 is assembled with the lock frame A235, so that the first locking spring A520 applies a pulling force to the lock hook drive plate A730 to rotate toward the lock hook limit plate A714. After the mechanical lock 232 is unlocked, the auxiliary tension of the first locking tension spring A520 can relatively easily drive the lock hook drive plate A730 to rotate, thereby driving the lock hook member A710 to move so that the lock hook A711 separates from the edge of the lock slot A2231 and enters the lock slot A2231, thereby separating the lock frame A235 from the lock plate. At this time, the security door box A230 can be rotated around the hinge to open, making it easier to remove the banknotes in the banknote bag. Preferably, the security door box A230 is also equipped with a handle 231, which is used to facilitate the operator to pull the security door box A230, banknote bag holder A220, and banknote bag A210 out of the safe 110 as a whole.

[0071] The security door box A230 is also provided with a banknote channel A234 and a security lock slide A236. A security lock plate A237 is installed on one side of the banknote channel A234 and the banknote channel A234 is connected to the inside of the banknote bag A210. The banknote channel A234 is closed by a security door A260. Security door guide wheels A261 are respectively installed on both sides of the security door A260. The security door guide wheels A261 are installed in the security lock slide A236 and engaged with it and can be slidably assembled. The security door A260 set The safety door screw A260 is assembled on the safety door screw A430 and is screwed therewith by a thread. One end of the safety door screw A260 is connected to the motor shaft of the safety door motor A340. After the safety door motor A340 is started, it can drive the safety door screw A260 to rotate in a circle, thereby driving the safety door A260 to move along the safety door screw A260, thereby pulling the safety door away from the banknote channel A234 to open the banknote channel A234, or moving toward the banknote channel A234 to close the banknote channel A234.

[0072] Preferably, the security door A260 is provided with a security door detection piece A262, which can be installed in the first security door sensor A351 and the second security door sensor A352. The first security door sensor A351 is installed at the position where the security door detection piece A262 is located when the security door A260 completely blocks the banknote passage A234, and the second security door sensor A352 is installed at the position where the security door detection piece A262 is located when the security door A260 completely does not block the banknote passage A234. The first security door sensor A351 and the second security door sensor A352 can be photoelectric sensors, so that when the security door detection piece A262 is installed, a signal is input to the industrial control computer, and the industrial control computer determines the current position of the security door based on the signal.

[0073] Preferably, a door box slide rail A233 is also provided on the outer wall of the safety door box A230, and the door box slide rail A233 is engaged and slidably installed in the door box slide groove A111, and the door box slide groove A111 is installed on the first mounting frame A110, and the first mounting frame A110 is assembled with the safe 110; the first mounting frame A110 is also installed with a second mounting frame A150, and the second mounting frame A150 is installed with a protective door frame A240, and the protective door frame A240 is provided with a banknote hopper A242, the banknote hopper A242 is hollow inside and open at both ends, and the bottom of the banknote hopper A242 is connected to the safe banknote inlet A238 on the safety door box A230, and the safe banknote inlet A238 is connected to the banknote channel A234. When in use, the banknotes first enter the banknote hopper, and when the safety door A260 is opened, the banknotes enter the banknote channel A234 from the banknote hopper and the safety banknote inlet A238, and finally fall into the banknote bag A210 for storage.

[0074] The top opening of the banknote hopper A242 is connected to the interior of the connecting tube 129. The connecting tube 129 is installed on the sorting module and connects the bottom of the banknote receiving platform 340 with the top of the banknote hopper A242, so that the banknotes that fall off the banknote receiving platform can be guided into the banknote hopper A242.

[0075] In order to prevent the banknotes in the banknote hopper from being taken out when the protective cover 320 is opened, causing losses, this embodiment further adds a protective door mechanism, which includes a protective door frame A240 and a protective door A250. The protective door frame A240 is also provided with a door frame slide groove A241, which is engaged with and slidably assembled with the protective door guide wheel A254. The protective door guide wheel A254 is installed on the protective door A250, and the protective door A250 is provided with a through door groove A251, a door drive plate A252, and a door drive groove A253. The door drive groove A253 is engaged with and slidably assembled with the door drive pin A411. The door drive pin A411 is installed on the door drive rod A410, and the door drive rod A410 is installed on the motor shaft of the protection door motor A310. In the initial state, the door slot A251 is not connected to the top of the banknote hopper A242 but is misaligned, allowing the protective door A250 to isolate the banknote hopper A242 from the connecting tube 129. When storing banknotes, the protective door motor A310 is activated, driving the door drive rod A410 to rotate. The door drive rod A410 drives the protective door A250 to slide along the door frame slide slot A241 until the door slot A251 connects the banknote hopper A242 with the connecting tube 129, allowing banknotes to fall into the banknote hopper 242. The protective door motor A310 then reverses, driving the protective door to reset.

[0076] Preferably, a door detection plate A412 is further mounted on the door drive rod A410, and a protective door sensor A320 is mounted on the protective door frame A240. When the door channel A251 connects the banknote hopper A242 to the connecting tube 129, the detection plate A412 is installed in the protective door sensor A320. The protective door sensor A320 sends a signal to the industrial computer, which determines that the door channel A251 connects the banknote hopper A242 to the connecting tube 129. The protective door sensor A320 can be a photoelectric sensor.

[0077] Preferably, the first mounting frame A110 is located on the door box slide A111 and is equipped with a blocking block A120 at one end close to the box door 111. The blocking block A120 can be axially slidably mounted on the blocking shaft A440. The blocking shaft A440 is located between the blocking block A120 and the first mounting frame A110 and is equipped with a blocking spring (not shown). The blocking spring is used to apply an elastic force to the blocking block A120 to push the second mounting frame A150, so that in the initial state, the blocking block A120 blocks the end of the door box slide A111, so that the door box slide rail A233 cannot be pulled out from the door box slide A111, so as to achieve the positioning and fixation of the safety door box A230. More preferably, a blocking and unlocking rod A450 can be axially slidably installed on the second mounting frame A150, and the bottom of the blocking and unlocking rod A450 is pressed against the top surface of the blocking block A120, so that when the safety door box A230 needs to be pulled out, the blocking and unlocking rod A450 is directly pressed down, so that the blocking and unlocking rod A450 drives the blocking block A120 to overcome the elastic force of the blocking spring and move downward, so that the blocking block A120 no longer blocks the door box slide A111, so as to facilitate the pulling out and loading of the safety door box A230.

[0078] Preferably, a detection frame A130 is further installed in the safe 110. The detection frame A130 is equipped with a detection pin A420 and a detection sensor A330. The detection pin A420 is inserted into and engages with a detection plate slot A141, allowing for slidable assembly. The detection plate slot A141 is provided on the detection plate A140. The detection plate A140 is assembled with one end of a detection spring A510, and the other end of the detection spring A510 is assembled with the detection frame A130. The detection spring A510 applies an elastic force to the detection plate A140, pulling the security door box A230. The detection plate A140 is provided with a detection edge A142, which can be assembled into the detection sensor A330, thereby causing the detection sensor A330 to send a signal to the industrial computer, which determines that the security door box A230 is properly installed. After the safety door box A230 is pulled out of the door box slide A111, the detection plate A140 moves toward the box door 111 under the tension of the detection spring A510, so that the detection edge A142 moves out of the detection sensor A330. At this time, the detection sensor A330 sends a signal to the industrial computer, and the industrial computer determines that the safety door box A230 is pulled out or not installed in place.

[0079] When the banknote receiving station needs to dispense banknotes, the protective door opens, connecting the banknote hopper to the receiving station. Banknotes then fall from the receiving station into the banknote hopper. The receiving station resets, the protective door closes, and the security door opens. Banknotes in the banknote hopper fall through the banknote channel into the banknote bag for storage. The security door closes, and this cycle continues. The security door is designed to only be opened by the security door motor A340, greatly enhancing the security of the banknotes in the banknote bag A210.
