Banknote digging driving mechanism and driving method thereof

Abstract

The invention relates to a banknote digging driving mechanism, comprising a first banknote digging wheel, a second banknote digging wheel, a third banknote digging wheel and a corresponding driving mechanism, and further comprising two sets of banknote stripping wheels and two sets of paddle wheels. The banknote stripping wheels are fixedly installed on a rotating shaft of the banknote stripping wheels and are interleaved with the second banknote digging wheel. The two ends of the rotating shaft of the banknote stripping wheels are movably provided with a shaft sleeve respectively, a pinion gear is fixed at the end of the shaft sleeve, and the pinion gear is meshed with a large gear fixedly installed at the end of a rotating shaft of the second banknote digging wheel; the paddle wheels arefixedly mounted on the shaft sleeves at two ends and drive the banknote to move with the second banknote digging wheel. The design of the mechanism avoids the phenomenon that multiple-banknote digging or empty-banknote digging often occurs in existing machines, which greatly reduces the failure rate of the machine. The banknote wear is greatly reduced, and the banknote peeling wheels are helped not to move or to rotate backwardly, so as to realize rollback operation of the banknote. In addition, a thickness sensor is arranged on the third banknote digging wheel to quickly detect the abnormalbanknote digging and prompt the system to stop digging and begin repairing.

Description

technical field [0001] The invention relates to a driving mechanism for digging banknotes and a driving method thereof, belonging to the field of financial equipment. Background technique [0002] In the field of financial equipment, the commonly used driving methods for digging banknotes rely on the friction between the digging wheel and the banknotes to be greater than the friction between the banknotes to achieve digging. The disadvantage of the common method is that the friction is not easy Control, if the friction force is too large, it is easy to wear banknotes or over-digging, which will cause losses to the bank; if the friction force is small, it may be empty or under-digged, which will increase the failure rate of its financial equipment. Simultaneously, in the prior art, the equipment for issuing and returning banknotes generally has technical defects such as complex structure, numerous parts, low reliability, high production cost, and insufficient user experience....

[0002] In the field of financial equipment, the commonly used driving methods for digging banknotes rely on the friction between the digging wheel and the banknotes to be greater than the friction between the banknotes to achieve digging. The disadvantage of the common method is that the friction is not easy Control, if the friction force is too large, it is easy to wear banknotes or over-digging, which will cause losses to the bank; if the friction force is small, it may be empty or under-digged, which will increase the failure rate of its financial equipment

At the same time, in the existing technology, the equipment for issuing and returning banknotes generally has technical defects such as complex structure, many parts, low reliability, high production cost, and insufficient user experience.
