Background
A sorter, also known as a banknote sorter, is a financial device for counting and sorting banknotes. When the banknote sorting machine is used for sorting banknotes, banknotes are placed on the sorting machine, the sorting device is used for sorting the banknotes, when the banknotes are few, the banknotes are in a fluffy state, pressure and friction between the sorting device and the banknotes are insufficient, the banknotes cannot be sorted or sorting errors are easily caused, and in order to solve the problem, the banknote pressing device needs to be arranged to apply appropriate pressure to the banknotes so as to ensure that the sorting work is carried out smoothly.
The existing banknote pressing device of the sorter is provided with a banknote pressing assembly for applying pressure and a driving motor for driving the banknote pressing assembly to move, a speed reducer is further arranged between the driving motor and the banknote pressing assembly, and the driving motor drives the banknote pressing assembly to move under the action of the speed reducer to apply pressure to banknotes on the sorter. The banknote pressing device has a complex structure and high manufacturing cost and maintenance cost; the cooperation between motor, speed reducer and bank note pressing component requires extremely high precision, leads to equipment stability not enough.
Another existing banknote pressing device of a sorter comprises an equipment rack, wherein a banknote dividing bottom plate and a banknote blocking plate are arranged on the rack, the banknote dividing bottom plate and the banknote blocking plate are used for placing stacked banknotes in a certain degree, a concave table is arranged in the middle of the banknote blocking plate, a guide rail groove is formed in the banknote blocking plate from the bottom of the concave table to the bottom of the banknote blocking plate, a banknote pressing plate is arranged in the concave table, the banknote pressing plate is driven by a driving device to be embedded in the concave table or popped out of the concave table, the banknote pressing plate popped out of the concave table moves downwards along the guide rail groove under the action of self weight, and a detection device for detecting whether the stacking height of the banknotes is higher than the height of the banknote pressing plate is arranged is further arranged on the rack. When the automatic paper money stacking machine works, paper money is placed on the paper money distributing bottom plate, and when the height of stacked paper money exceeds the height of the paper money pressing plate, the paper money pressing plate is fixed in the concave platform; along with the sorting operation, when the height of the stacked bank notes is lower than the height of the bank note pressing plate, the detection device sends out a detection signal, the control system controls the driving device to work, the driving device drives the bank note pressing plate to pop out from the concave table, the popped bank note pressing plate is pressed above the bank notes under the action of self weight, and the ejected bank note pressing plate continuously descends and is pressed above the bank notes along with the reduction of the stacking height of the bank notes; when the sorting work is finished, the banknote pressing plate is driven by the driving device to ascend and is folded in the concave table again. The banknote pressing device needs to arrange a gathering and ejecting device of the banknote pressing plate and a driving component between the driving device and the banknote pressing plate in the device, and has complex manufacturing process and high production and maintenance cost; meanwhile, the folding and the ejecting of the banknote pressing plate both require higher control precision and matching precision, so that the stability of the device is poor; moreover, the bank note pressing plate is frequently folded and popped up, and the internal components of the bank note pressing plate are easily abraded after long-time use, so that the precision is reduced, and even the equipment is damaged.
