[0045] The banknote guide rotating shaft 530 also passes through the part of the upper banknote guide rack 180 located between the two vertical plates 110 and is rotatably assembled with it in a circumferential manner. Screws pass through the banknote guide rotating shaft 530 and are assembled and fixed with the side wall of the upper banknote guide rack 180, so that when the banknote guide rotating shaft 530 rotates in a circle, it can drive this end of the upper banknote guide rack 180 to rotate synchronously;

[0046] One end of the upper banknote guide rack 180 away from the banknote guide rotating shaft 530 is rotatably assembled with a locking shaft 240. Both ends of the locking shaft 240 pass through the upper banknote guide rack 180 and are respectively hinged to a first locking plate 210 and a second locking plate 250. First locking grooves 211 and second locking grooves 251 are respectively arranged on the first locking plate 210 and the second locking plate 250, and the first locking grooves 211 and the second locking grooves 251 are respectively engaged and assembled with a first locking rod 221 and a second locking rod 223, and the first locking rod 221 and the second locking rod 223 are respectively fixed on the bottom plate edge 141;

[0047] A tension spring hole 212 is further provided on the first locking plate 210. One end of the tension spring 230 is fixedly assembled and hooked with the tension spring hole 212, and the other end of the tension spring 230 is fixedly assembled and hooked with the tension spring post 222.

The edge 121 of the top cover is provided on the top cover 120, and the top cover 120 is used to seal the top of the upper banknote guide 180. The tension spring 230 is used to generate a pulling force on the first locking plate 210 to rotate towards the first locking rod 221.

[0049] When it is necessary to open the upper banknote guide 180, first take out the first locking plate and the second locking plate from the first locking rod and the second locking rod, and then rotate upward around the banknote guiding rotating shaft 530 to open the gap (banknote passage 101) between the upper banknote guide 180 and the lower banknote guide plate, so as to facilitate maintenance and repair.

[0050] A placing protrusion 184 is provided at the bottom of the upper banknote guide 180 near one end of the first banknote inlet guide plate 130. The placing protrusion 184 is fitted and assembled with a placing groove 131 provided on the first banknote inlet guide plate 130, and the first banknote inlet guide plate 130 is fixed on the bottom plate 140.

[0065] A detection fixing block 320 is fixed on the detection mounting block 310. A detection sliding groove 321 is arranged inside the detection fixing block 320. A detection driving groove 313 communicating with the detection sliding groove 321 is arranged on the detection mounting block 310. The detection mounting block 310 is further respectively provided with a detection movable groove 312 and a detection pressing inclined surface 311. The detection pressing inclined surface 311 is arranged on the inner wall of the detection movable groove 312;

[0066] Several movable detection blocks 330 are installed in the detection movable groove 312. The movable detection blocks 330 are rotatably installed on a detection rotating shaft 560. Two ends of the detection rotating shaft 650 are respectively installed on the side walls at two ends of the detection movable groove 312;

[0067] Clamping protrusions 331, driving protrusions 332 and hinged rings 333 are respectively arranged on the movable detection blocks 330. The hinged rings 333 are assembled with a detection pressing shaft 550. The induction pressing wheel 472 is rotatably installed on the detection pressing shaft 550;

[0068] A detection rod 340 and a large end of the detection rod 342 are respectively slidably installed in the detection sliding groove 321 and the detection driving groove 313. A third compression spring 350 is sleeved on the part of the detection rod 340 between the large end of the detection rod 342 and the detection sliding groove 321. The third compression spring 350 is used to apply an elastic force to the large end of the detection rod 342 to hinder its upward movement;

[0069] One end of the detection rod 340 far from the large end of the detection rod 342 passes through the detection sliding groove 321 and is fixedly assembled with a detection protrusion 341. The detection protrusion 341 has magnetism. Hall sensors 632 are installed on the detection fixing block 320 and the detection protrusion 341. The Hall sensors 632 are used to detect the displacement of the detection protrusion 341.

[0070] A main board 631 is installed between the top cover 120 and the bottom plate 181 of the banknote guiding frame. A controller (PLC or CPU) is installed on the main board 631. The signal end of the controller is in communication connection with the signal ends of the microswitch, the Hall sensor, the first photoelectric counter and the second photoelectric counter, so as to know the working condition of the present invention in real time.

[0071] Preferably, the driving protrusion 332 is located directly above the detection pressing shaft 550 and abuts against the bottom surface of the large end of the detection rod 342; the detection pressing inclined surface 311 is inclined downward from top to bottom and from the end close to the detection driving groove 313 to the other end, and the distance between the detection pressing inclined surface 311 and the detection driving groove 313 gradually increases from top to bottom.

[0072] When the banknote passes between the induction pressure wheel 472 and the third banknote feeding wheel 463, the thickness of the banknote will drive the induction pressure wheel 472 and the movable detection block 330 to rotate upward around the detection rotating shaft 560, so that the clamping protrusion 331 and the driving protrusion 332 rotate synchronously. This makes the clamping protrusion 331 gradually rotate towards the detection pressing inclined surface 311 and the driving protrusion 332 gradually rise. The rising of the driving protrusion 332 will drive the detection rod 340 to move upward against the elastic force of the third compression spring, so that the detection protrusion 341 moves upward. At this time, the Hall sensor 632 detects the displacement and determines that the banknote has passed. Once the detection protrusion 341 does not move downward for a long time, it is determined that banknote jamming occurs. At this time, the external industrial control computer can receive the Hall sensor signal and then start the sound and light alarm for warning.

[0073] The larger the angle at which the clamping protrusion 331 rotates towards the detection pressing inclined surface, the greater the resistance generated by the induction pressure wheel 472, thus avoiding the situation that the resistance of the induction pressure wheel 472 is too small to press the banknote tightly, or a large amount of banknotes gather at the induction pressure wheel 472 after banknote jamming, resulting in jamming here. After the banknote passes through the induction pressure wheel 472, the detection rod 340 moves downward and resets under the action of the third compression spring.

[0074] Preferably, the third banknote feeding wheel 463 can move relative to the third banknote feeding shaft 513 in the circumferential direction. In this embodiment, the inner hole of the third banknote feeding wheel 463 is designed to be slightly larger than the outer diameter of the third banknote feeding shaft 513, and the inner hole of the third banknote feeding wheel 463 and the outer diameter of the third banknote feeding shaft 513 are assembled through splines.

[0075] A microswitch 700 is installed on the side of the third banknote feeding wheel 463 away from the induction pressure wheel 472. The microswitch 700 and the third banknote feeding wheel 463 correspond to each other one by one, and the trigger end of the microswitch 700 faces the bottom of the third banknote feeding wheel 463. The microswitch 700 is installed on the induction support plate 710, and the induction support plate 710 is installed in the lower banknote guide frame 190. Once a banknote that is too thick passes between the induction pressure wheel 472 and the third banknote feeding wheel 463 or banknote jamming occurs here, the distance between the induction pressure wheel 472 and the third banknote feeding wheel 463 increases, thereby pushing the third banknote feeding wheel 463 towards the microswitch until the microswitch is triggered. The microswitch transmits a signal to the external industrial control computer, thereby determining a fault here, and then a reminder instruction can be generated to notify the operator to deal with it in time through a preset device or method.

[0076] A first photoelectric counter 621 and a second photoelectric counter 622 are respectively installed at the inlet and outlet of the banknote channel 101. The first photoelectric counter 621 and the second photoelectric counter 622 are respectively used to sense the passing of banknotes and count according to the number of passes.

[0077] The CIS sensor includes an upper CIS sensor 641 and a lower CIS sensor 642. The upper CIS sensor 641 and the lower CIS sensor 642 are respectively used to acquire images of both ends of the banknote for discrimination. The upper CIS sensor 641 and the lower CIS sensor 642 are respectively installed on the upper banknote guide 180 and the lower banknote guide 190. The lower banknote guide 190 is installed on the bottom plate, and the banknote outlet plate is installed on the upper banknote guide 180.

[0078] The magnetic reader 650 is used to read magnetic marks (magnetic ink) on the banknote to further determine the authenticity of the banknote.

[0079] In use, the banknote enters the banknote channel 101 from one end close to the second banknote feeder 170 of the banknote channel, and then passes through the CIS sensor to acquire the banknote image for discrimination. Then it is input into the detection module to judge the thickness of the banknote or whether there is a jam here. Then it is input into the magnetic reader 650 to read the magnetic mark of the banknote for further verification. Generally, the magnetic mark is the banknote code. By comparing the banknote code with the banknote code library of the bank, if it exists, it is judged as a genuine banknote, otherwise it is a counterfeit banknote. Finally, the present invention is output. This method is in a pipeline form, with high efficiency and quite high discrimination accuracy, and can meet the current requirements.
