[0025] When in use, the mercury lamp 500 emits ultraviolet light to irradiate the banknotes to sterilize the banknotes, and the CIS module 330 scans the banknotes to determine the authenticity of the banknotes. Of course, a photoelectric counter is also provided between the banknote twisting wheel and the banknote receiving wheel, and the photoelectric counter is used to count the number of banknotes passing through to count the number of banknotes.

[0026] When in use, banknotes 01 are placed in stacks on the banknote feeding plate 120, and the banknote feeding wheels 420 rotate to transport the banknotes one by one to between the two mercury lamps 500. The sterilization module 500 sterilizes the banknotes by irradiating them with ultraviolet light; the banknotes are sent to the CIS module for scanning and identification through a group of banknote feeding wheels 420, and then sent to the banknote receiving wheels 430 through another group of banknote feeding wheels 420. The banknote receiving wheels 430 stack the banknotes in stacks on the banknote receiving plate 111.

[0027] Preferably, the banknote twisting wheel shaft 411 is connected to the motor shaft of the first motor 310 through the first belt 610 to form a belt transmission mechanism, and the banknote twisting wheel shaft 411 is also connected to the banknote feeding wheel shaft 421 adjacent thereto through the second belt 620 to form a belt transmission mechanism, and the two banknote feeding wheel shafts 421 are connected to each other through the third belt 630 to form a belt transmission mechanism. When in use, the first motor is started, thereby driving the banknote twisting wheel and the banknote feeding wheel to rotate, so as to twist and feed banknotes.

[0028] Preferably, the banknote receiving wheel shaft 431 is connected to the motor shaft of the second motor 320 through a fourth belt to form a belt transmission mechanism. After the second motor 320 is started, it can drive the banknote receiving wheel 430 to operate to receive banknotes.

[0029] Preferably, the mercury lamp 500 includes a lamp tube 510, a lamp holder 520, and a lamp base 530. The lamp base 530 is installed on the housing 110. There are two lamp holders 520, which are respectively installed at both ends of the lamp tube 510. The lamp holder 520 is inserted into the lamp base 530, so that the lamp holder is powered by the lamp base. After power is supplied, the lamp tube emits ultraviolet light.

[0030] See also Figure 8-Figure 14 Since banknotes carry some dust, fibers, etc., which are easily adsorbed on the mercury lamp and block the mercury lamp, and the method of regularly disassembling the mercury lamp for cleaning is rather troublesome, the applicant has also designed a brushing mechanism for cleaning the mercury lamp.

[0031] The brushing mechanism includes a brushing frame 140, on which two mutually parallel first brushing frame plates 141 are installed, and between the two first brushing frame plates 141 are two mutually parallel second brushing frame plates 142; the two first brushing frame plates 141 are respectively assembled with the lamp holder 530 so as to be rotatable in a circle, and the lamp holder 530 is connected to the current through the electric slip ring 360; when the mercury lamp 500 rotates, the electric slip ring 360 is continuously powered.

[0032] The two second scrubbing rack plates 142 are also respectively assembled with the two ends of the lampshade 160. The lampshade 160 is provided with an opening at the corresponding position of the lamp tube 510, and the light emitted by the lamp tube 510 is irradiated to the banknotes through the opening. The lamp holder 530 and the lampshade 160 can be assembled in a circular rotation, and the lampshade 160 is provided with a lampshade limit strip 161; the lamp holder 530 is provided with a first rotating gear 661 which is not rotatable in a circular manner, and the end of the lampshade 160 close to the second scrubbing rack plate 142 is provided with a first closed gear 671 which can be rotatable in a circular manner; the first rotating gears 661 corresponding to the two mercury lamps 500 are meshed and transmitted through the second transmission gear 662, and one of the first rotating gears 661 is meshed and transmitted with the third transmission gear 663, and the first rotating gear ... The second transmission gear 662 and the third transmission gear 663 are respectively mounted on the first intermediate shaft 451 and the second intermediate shaft 452. The first intermediate shaft 451 and the second intermediate shaft 452 are respectively assembled with the first brush frame plate 141 so as to be rotatable in a circular manner. The second intermediate shaft 452 is connected to the motor shaft of the third motor 340 through the fourth belt 640 to form a belt transmission mechanism. After the third motor is started, it can drive the second intermediate shaft 452 to rotate, thereby driving the two first rotating gears 661, that is, driving the two mercury lamps 500 to rotate.

[0033] A brush plate 810 is also installed between the two second brushing racks 142. A plurality of elastic bristles 811 are installed on the brush plate 810. The bristles 811 can be pressed tightly against the lamp tube 510. When the mercury lamp rotates, the surface of the lamp tube can be brushed by the bristles, thereby cleaning the debris on the surface of the lamp tube. In this embodiment, a time period can be set to automatically clean the lamp tube regularly. A through-hole for the lampshade 160 is provided at the corresponding position of the brush plate 810. After the bristles pass through the through-hole for the lampshade, they are pressed tightly against the lamp tube.

[0034] Preferably, in order to prevent the debris brushed off the lamp tube from contaminating other components, the present embodiment is further improved as follows:

[0035] A shielding cloth 710 is added, one end of which is assembled with the driving strip 713, and the other end of the shielding cloth 710 passes through the gap between the fourth roller 464 and the lampshade 160, the gap between the third roller 463 and the lampshade 160, and the second roller 462 in sequence, and then is assembled with the winding wheel 712. The winding wheel 712 is mounted on the first roller 461, and the first roller 461, the second roller 462, the third roller 463, and the fourth roller 464 are respectively assembled with the second brush frame plates 142 on both sides thereof so as to be rotatable in a circle, and the driving strip 713 is assembled with the first closed gear 671. When in use, the first closing gear 671 is driven to rotate, which can drive the driving bar 713 to rotate along the lampshade 160, thereby driving the shielding cloth 710 to rotate along the lampshade 160 until the driving bar 713 is pressed tightly against the lampshade limiting bar 161. At this time, the shielding cloth 710 closes the opening of the lampshade, and then the mercury lamp is rotated, and the brushed debris will fall on the shielding cloth 710, thereby avoiding secondary pollution.

[0036] More preferably, the shielding cloth 710 is provided with a suction opening 711, and a negative pressure cover 170 is installed between the third roller 463 and the fourth roller 464. The negative pressure cover 170 presses the shielding cloth 710 against the lampshade 160 to achieve a certain sealing effect, and the negative pressure cover 170 is installed on two second brush racks 142. The interior of the negative pressure cover 170 is a hollow negative pressure chamber 171 with one side open. The brush plate 810 is installed in the negative pressure chamber 171. The negative pressure chamber 171 is connected to the negative pressure pipe 440 through the negative pressure branch pipe 441, and the negative pressure pipe 440 is connected to the negative pressure source (negative pressure pump). When the driving bar 713 is pressed against the lampshade limit bar 161, the suction opening 711 is located in the negative pressure chamber 171, and the negative pressure pipe is connected to the negative pressure, so that the debris brushed off the lamp tube is sucked away to prevent secondary pollution. In this embodiment, the shielding cloth can be replaced by a silicone sheet, so that a better sealing effect can be obtained between the shielding cloth and the lampshade and the negative pressure cover.

[0037] More preferably, the first roller 461 is relatively fixed to one end of the coil spring 370, and the other end of the coil spring 370 is relatively fixed to the first brush frame plate 141. The coil spring 370 is used to keep the first roller 461 in a reeled state, that is, the lampshade is in an open state. The shielding cloth is reeled on the reel wheel 712, and when the shielding cloth is pulled out, it drives the first roller 461 to rotate, so that the coil spring is reeled and elastic force is stored. After cleaning is completed, the first closed gear 671 is reversed, so that the shielding cloth 710 is released, and then the coil spring drives the first roller 461 to reverse and reel the shielding cloth 710.

[0038] The first closed gears 671 of the two mercury lamps mesh with each other for transmission, wherein one of the first closed gears 671 meshes with the second closed gear 672 for transmission, and the second closed gear 672 is sleeved on the third intermediate shaft 453, and the third intermediate shaft 453 is connected to the motor shaft of the fourth motor 350 through the fifth belt 650 to form a belt transmission mechanism. After the fourth motor 350 is started, it drives the third intermediate shaft 453 to rotate, thereby driving the two first closed gears 671 to rotate, so as to achieve the shielding cloth to block or open the lampshade. In this embodiment, since the bristles are elastic, the bristles can be bent when the shielding cloth moves, so that the shielding cloth moves smoothly. Preferably, reflective paint is sprayed on the end face of the shielding cloth facing the lampshade, so that the end face of the shielding cloth facing the lampshade forms a mirror surface to reflect light and increase the irradiation effect of ultraviolet light.

[0039] Preferably, a semicircular groove 1421 is provided on the second brush rack plate 142 to enable the lampshade limit strip 161 to rotate. The semicircular groove 1421 is used to prevent the second brush rack plate 142 from interfering with the rotation of the lampshade limit strip 161 on the one hand, and to limit the rotation angle of the lampshade limit strip 161 on the other hand.

[0040] The matters not described in detail in the present invention are all known technologies to those skilled in the art.

[0041] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
