[0031] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and implementation modes.

[0032] like Figure 5 As shown, the high-speed large-amount deposit and withdrawal machine includes a withdrawal port 1 for temporarily placing and withdrawing banknotes, a deposit port 2 for temporarily placing and depositing banknotes, an identification module 3 for distinguishing the authenticity of banknotes, a banknote box for storing transaction banknotes, a transmission path for transmitting banknotes, and a control unit. In terms of spatial structure, the deposit and withdrawal machine is divided into an upper part, a middle part, and a lower part. The upper part includes a withdrawal port and a deposit port, the middle part includes an upper front-end transmission assembly 6, an upper rear-end transmission assembly 7, a lower transmission assembly 8, and an identification module 3, and the lower part includes a banknote box, which includes a recovery banknote box 4 and a circulation banknote box 5. The upper part and the middle part are connected by a banknote inlet and outlet channel 9, and the upper front-end transmission assembly 6 is connected to the withdrawal port 1 and the deposit port 2 by the banknote inlet and outlet channel 9, and the identification module 3 is located between the upper front-end transmission assembly 6 and the upper rear-end transmission assembly 7.

[0033] like Figure 1 As shown, a banknote rubbing mechanism is used below the withdrawal port 1 of a high-speed large-value deposit and withdrawal machine, comprising a banknote digging wheel 10, a banknote rubbing wheel 11 and a banknote guide plate 12. The banknote rubbing wheel 11 is provided with an arc-shaped friction portion 13, and the surface of the banknote digging wheel 10 is provided with an annular banknote rubbing portion 14. The banknote digging wheel and the banknote rubbing wheel rotate in the same direction, and the banknote digging wheel and the banknote rubbing wheel are arranged at intervals.

[0034] The banknote rubbing mechanism also includes a sector gear 15. Figure 2As shown, the fan-shaped gear and the banknote rubbing wheel are both located on the banknote rubbing wheel core shaft 16, and the fan-shaped gear and the banknote rubbing wheel realize synchronous movement driven by the banknote rubbing wheel core shaft. The fan-shaped gear is provided with gear teeth 17, and the central angle corresponding to the gear tooth length is equal to the central angle corresponding to the arc-shaped friction part. The banknote rubbing wheel drives the banknote digging wheel to rotate through the meshing of the fan-shaped gear, and the fan-shaped gear realizes meshing transmission with the banknote digging wheel through two gears.

[0035] When there are banknotes that customers forget to take away at the cash withdrawal port, the control unit starts the banknote rubbing mechanism to start working. The banknote rubbing wheel rotates under the drive of the motor, and at the same time drives the banknote digging wheel to rotate through the meshing of the fan gear. The banknote rubbing wheel and the banknote digging wheel rotate in the same direction to complete the banknote grinding, and rub the banknotes in the cash withdrawal port back to the recovery banknote box. When the fan gear is out of meshing with the gear, the banknotes have been taken away by the banknote rubbing wheel, and the banknote digging wheel no longer rotates with the banknote rubbing wheel. The banknote digging wheel does not actively rotate when not needed, so the speed of the banknote digging wheel will decrease, and it does not have the ability to dig out banknotes, reducing the risk of rubbing duplicate and continuous banknotes. Since this mechanism is used for the forgotten recovery function, when the banknotes are rubbed back to the banknote box, it occurs in the absence of personnel, and it is necessary to reduce abnormal situations such as duplicate and continuous banknotes to prevent banknote jams due to such abnormalities, causing the machine to stop working and causing the loss of banknotes.

[0036] In order to ensure that the banknotes are taken away by the rubbing wheel when the sector gear is out of meshing relationship with the gear, we calculate the time it takes for the banknote to reach the rubbing wheel from the banknote digging wheel based on the width of the banknote with the largest denomination and the speed of the rubbing wheel. The length of the teeth on the sector gear is determined by this time and speed.

[0037] The diameter of the bill-digging wheel is smaller than that of the bill-grinding wheel, shortening the center distance between the bill-grinding wheel and the bill-grinding wheel. In the case of mixed-denomination bill-grinding, the bill-digging wheel can adapt to bills with smaller widths, and has better compatibility with bills with different denominations and widths. In the prior art, the diameter of the bill-digging wheel is roughly equal to the diameter of the bill-grinding wheel. Considering that the two rotate in the same phase, and the bill-digging wheel rotates one circle to dig out one bill, if the diameter of the bill-digging wheel is too small, it cannot be guaranteed that the bill-digging wheel rotates one circle to dig out one bill, increasing the risk of duplicate and continuous bills; however, the fan-shaped gear is designed in the present invention, which does not actively rotate when the bill-digging wheel is not needed, providing a prerequisite for reducing the diameter of the bill-digging wheel.

[0038] The banknote rubbing mechanism is also provided with a frame plate 18. Figure 3As shown, the frame plate is provided with two springs 19, one end of the two springs is connected to the frame plate, and the other end is fixed to the sheet metal frame (not shown in the figure). One side of the frame plate is connected to the banknote rubbing wheel core shaft through a bearing 20, and can be rotated around the banknote rubbing wheel core shaft. The position where the two springs are connected to the frame plate is close to the banknote rubbing wheel core shaft. The other side of the frame plate is overlapped on the banknote guide plate. The frame plate is provided with an opening 21, and the banknote digging wheel emerges from the surface of the frame plate through the opening. The frame plate here can prevent banknotes from drilling into the banknote digging wheel, and does not affect the rotation of the banknote digging wheel.

[0039] The two gears are a transmission gear 22 and a reversing gear 23, and the reversing gear is rotatably connected to the frame plate through a gear shaft 26. The frame plate is provided with a lap hole 27, which is semicircular, and the frame plate is lapped on the banknote digging wheel core shaft 28 through the lap hole. When a banknote is jammed and the frame plate needs to be manually pulled up, the circle centers of the sector gear and the two gears are not in a straight line, and the reversing gear will move away from the transmission gear with the frame plate under the drive of the gear shaft, so as to separate the frame plate from the banknote guide plate; when the frame plate is released, it will return to the original path under the action of the restoring force of the two springs and contact the banknote guide plate. In the working state, due to the action of the spring tension, the frame plate will also be always lapped on the banknote guide plate to prevent the banknote from drilling into the banknote digging wheel and jamming.

[0040] The sector gear is provided with a fixing ring 24, the width of which is greater than the width of the gear teeth 17, and screw holes (not shown) are provided on the fixing ring and the axle of the banknote rubbing wheel, through which fixing screws are passed to fix the sector gear and the axle of the banknote rubbing wheel.

[0041] A mounting positioning groove 25 is provided in the fixed circular ring of the sector gear.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
