Two mercury lamps 200 are installed on the banknote passage 111, and the two mercury lamps are respectively installed on both sides of the banknote passage 111. When in use, the banknote is transported from the banknote passage 111, and then passes through banknote verification, identification, and between the two mercury lamps 200 in sequence, and finally transported to the corresponding banknote receiving plates according to the identified denomination, currency, etc. to complete sorting. When the banknote 01 passes between the two mercury lamps 200, the mercury lamps 200 emit ultraviolet light to irradiate the two end faces of the banknote to sterilize and disinfect the banknote.

[0024] The mercury lamp 200 includes a lamp tube 210 and a lamp holder 220. A power supply rod 221 is provided on the lamp holder 220. The lamp holder 220 is assembled with a lamp holder 170. A conductive member 310 is installed on the lamp holder 170. A groove 311 is provided on the conductive member 310.

The bristles are elastic and pressed against the lamp tube 210. Roller brush tables 622 are also arranged on both sides of the roller brush 620. The roller brush tables 622 are inserted into the roller brush retaining groove 522 and can be rotatably assembled therewith. The arc strip 550 fits with the roller brush table 622 and can be slidably assembled.

[0030] The outer wall of the roller brush 620 is pressed and driven with the roller brush power wheel 630, and the roller brush power wheel 630 can be rotatably mounted on the roller brush wheel shaft 420, and the roller brush wheel shaft 420 and the roller brush side plate 530 can be rotatably assembled, and the roller brush side plate 530 is installed on the roller brush end block 510; the roller brush power wheel 630 is pressed and driven with the roller brush belt 640, and the roller brush belt 640 passes around the first pulley 641 and the second pulley 642 respectively to form a belt transmission mechanism, and the first pulley 641 and the second pulley 642 are respectively The screw rod 410 and the pulley shaft 430 are mounted on the pulley shaft 430, and the pulley shaft 430 and the adjustment frame plate 541 can be assembled in a circular rotation. The adjustment frame plate 541 is installed on the adjustment frame 540, and the adjustment frame 540 is assembled with one end of the optical axis 440. The other end of the optical axis 440 is mounted with a spring 710 and then passes through the roller brush end block 510 and can be axially slidably assembled with it. The spring 710 is used to apply an elastic force to the adjustment frame 540 to push the roller brush power wheel 630, so that the roller brush belt is kept in close transmission with the roller brush power wheel 630. Preferably, a nut 441 is installed on one end of the optical axis 440 passing through the roller brush end block 510, and the nut 441 is used to limit the maximum displacement of the adjustment frame 540 to the roller brush power wheel 630.

[0031] Preferably, the roller brush side plate 530 is provided with a movable groove 531, and both ends of the pulley shaft 430 are inserted into the movable groove 531 and engaged therewith and slidably assembled. This design is mainly to maintain the support for the adjustment frame 540 and guide the movement of the adjustment frame.

[0032] Preferably, the roller brush seat 520 is provided with a seat groove 521, the first belt wheel 641 is installed in the seat groove 521, and a screw hole seat 560 is also installed in the seat groove 521, and the screw hole seat 560 is sleeved on the screw rod 410 and assembled with it through a thread.

[0033] In the initial state, the roller brush assembly 500 is located at one end of the lamp tube, and the open end of the roller brush 620 faces the banknote channel 111, so as to avoid affecting the passage of banknotes and blocking ultraviolet light. When the surface of the lamp tube needs to be cleaned, the motor is started, and the motor drives the two screws to rotate in a circle. The screw drives the roller brush assembly 500 to move along the axial direction of the screw through the thread engaged with the screw hole seat 560. At the same time, the screw drives the first pulley to rotate, and the first pulley drives the roller brush belt 640 to run. The roller brush belt 640 drives the roller brush power wheel 630 to rotate in a circle through friction, and the roller brush power wheel 630 drives the roller brush 620 to rotate in a circle through friction, so that the roller brush 620 presses the lamp tube to move axially while continuously rotating itself in a circle to greatly increase the cleaning effect. In this embodiment, the circle proportion occupied by the arc strip 550 is at least 3 / 4 of the entire circle, and the arc length of the roller brush holding groove 522 is greater than the opening arc length of the roller brush 620. This prevents the roller brush 620 from being separated from the roller brush and the roller brush stand 622 from being completely separated from the roller brush retaining groove 522 .
