## Abstract

A banknote receiving device includes a supporting frame; a pair of roller wheels, located at an inlet of the banknote receiving device and configured to bring in banknotes by clamping; a blade wheel, mounted on the supporting frame via a rotating shaft, the blade wheel being joined with the pair of roller wheels and configured to convey the banknotes delivered from the pair of roller wheels in a way of carrying the banknotes and rotating at a high speed; and a support plate, located below the blade wheel, configured to carry the banknotes delivered from the blade wheel. The banknote receiving device further includes a blade wheel floating control device configured to control an upward and downward floating of the blade wheel and to further control the support plate to move downward according to an upward floating degree of the blade wheel to increase the banknote receiving space.

## Claims

### Claim 1

A banknote receiving device, comprising:
a supporting frame, configured to mount subsequent components;
a pair of roller wheels, located at an inlet of the banknote receiving device and configured to bring in banknotes by clamping;
a blade wheel, mounted on the supporting frame via a rotating shaft, the blade wheel being joined with the pair of roller wheels and configured to convey the banknotes delivered from the pair of roller wheels in a way of carrying the banknotes and rotating at a high speed; and
a support plate, located below the blade wheel, configured to carry the banknotes delivered from the blade wheel, the support plate being movable up and down under the action of a transmission mechanism to adjust a size of a banknote receiving space;
wherein the banknote receiving device further comprises a blade wheel floating control device configured to control an upward and downward floating of the blade wheel and to further control the support plate to move downward according to an upward floating degree of the blade wheel to increase the banknote receiving space; and the supporting frame comprises two lateral plates having the same structure, each of the lateral plates is provided with a shaped hole, and two ends of the rotating shaft are respectively mounted in the shaped holes of the two lateral plates via respective bearings; and
wherein, the blade wheel floating control device comprises:
a coded disc, which is fixed on the rotating shaft, is rotatable synchronously with the blade wheel and floatable up and down with the blade wheel;
a sensor, fixed above the coded disc, wherein the coded disc is configured to optionally block a light-transmittable point of the sensor when the coded disc floats up and down with the blade wheel, to allow the sensor to sense the upward floating degree of the blade wheel; and
a pair of tension springs arranged symmetrically, each of the tension springs having an upper end fixed on the respective bearing of the rotating shaft and a lower end fixed on the respective lateral plate of the supporting frame.

### Claim 2 (depends on 1)

The banknote receiving device according to claim 1, wherein each of the bearings comprises an inner bearing and an outer bearing, the inner bearing is sleeved on the rotating shaft and arranged in the respective shaped hole of the supporting frame, the outer bearing is sleeved on the inner bearing and assembled on the rotating shaft, and is not assembled in the shaped hole of the supporting frame, and the outer bearing is fixed to a small supporting piece, and the small supporting piece is provided with a small hole for hanging the tension spring.

### Claim 3 (depends on 2)

The banknote receiving device according to claim 2, wherein the shaped hole is defined by two overlapping circles, a distance between centers of the two overlapping circles is 3 mm, and a diameter of each of the two overlapping circles hole is slightly greater than an outer diameter of the inner bearing.

### Claim 4 (depends on 1)

The banknote receiving device according to claim 1, wherein an initial position of the coded disc is located at a position 0.7 mm below the light-transmittable point of the sensor.

### Claim 5 (depends on 1)

The banknote receiving device according to claim 1, wherein the banknote receiving device further comprises a controller configured to receive a signal of the sensor being blocked and control the support plate to move downward by a predetermined distance.

### Claim 6

A blade wheel floating control device, comprising:
a supporting frame, having two lateral plates having the same structure, each of the lateral plates being provided with a shaped hole;
a rotating shaft, two ends of which are respectively mounted in the shaped holes of the two lateral plates of the supporting frame, wherein the rotating shaft is floatable up and down in the shaped holes, and a blade wheel is mounted on the rotating shaft and is rotatable around the rotating shaft at a high speed;
a coded disc, which is fixed on the rotating shaft, is rotatable synchronously with the blade wheel and floatable up and down with the rotating shaft;
a sensor, fixed above the coded disc, wherein the coded disc is configured to optionally block a light-transmittable point of the sensor when the coded disc floats up and down with the rotating shaft, to allow the sensor to sense an upward floating degree of the blade wheel; and
a pair of tension springs arranged symmetrically, each of the tension springs having an upper end fixed on a small supporting piece of a respective outer bearing of the rotating shaft and a lower end fixed on the respective lateral plate of the supporting frame.

### Claim 7 (depends on 6)

The blade wheel floating control device according to claim 6, wherein an initial position of the coded disc is located at a position 0.7 mm below the light-transmittable point of the sensor.

### Claim 8 (depends on 6)
