1. Transmission part
Transmission part（Money counter） The transmission part is driven by a large motor, and the large motor transmits the power to each rotating shaft through a conveyor belt and a transmission wheel, which drives the rotation of the banknote twisting wheel, the banknote pressing wheel, and the picking wheel (the banknote receiving part with a small motor is driven by a small motor). transmission).
a. Twisting part
The banknote twisting part（Money counter） is mainly composed of a banknote feeder and a banknote twisting wheel. The banknote feeder is mainly composed of a banknote receiving panel, a five-finger steel sheet, a resistance rubber, a plastic banknote board, and an adjusting screw. Twisting out the banknotes to be counted one by one is a prerequisite for ensuring accurate counting. The realization principle is as follows:
The banknote twisting wheel twists the first banknote on the surface, and the banknote below is stuck by the resistance rubber, so that the first banknote is separated from the banknote below to achieve splitting. This process is repeated until the last banknote is twisted. . The note-feeding station and the note-twisting wheel mainly play the role of note-separating, and the resistance skin and the five-finger steel sheet have a direct impact on the speed of note delivery and the effect of note-separating.
The money-twisting wheel has a certain degree of flexibility. When the money-twisting wheel is worn, it will affect the banknote separation performance of the banknotes. It is easy to tilt the banknote. After the money-twisting wheel is worn, only the money-twisting wheel needs to be replaced, without the need to replace the wheel core.（Money counter）
When the banknotes are not loaded smoothly and the banknotes are misreported or the counting is not accurate, the adjustment screw of the banknote feeder can be properly tightened. Pay attention to not too tight when adjusting the adjustment screw of the banknote feeder, otherwise the twisting wheel and the resistance skin will accelerate the wear; also not too loose, otherwise it is easy to tilt the banknotes and easy to issue the banknotes. Pull the exercise coupon to prevent the paper from going down and place it on the cash feed table. Feel the tension of the cash feed table. The left and right tension must be the same. If not, you can adjust the seven-character adjustment piece.
The function of the magnet is to enhance the magnetism of the paper money. The magnet has polarity and direction. When replacing the magnet, pay attention to the installation direction. If the large magnet is installed reversely, each piece will be falsely reported. Stable and prone to false alarms.
b. Dispenser part（Money counter）
The banknote output part is mainly composed of a banknote pressing wheel and a counter-rotating wheel. The banknote pressing wheel effectively separates the first-arriving banknotes from the following banknotes at twice the speed of the twisting wheel. Distinguish.
C. Receiving part
(1) Determination of the center position of the banknote receiving wheel: The center of the banknote receiving wheel should be as close to the delivery axis as possible. Shallow and fly money.（Money counter）
(2) The shape of the vane: the curve of the vane should make the banknote bend and deform after it is inserted. The larger the deformation of the banknote, the more difficult it is to come out. The vanes of the banknote-receiving wheel should be aligned and parallel without deformation.
(3) The speed of the receiving wheel: the faster the speed of the receiving wheel, the easier it is to fly the money, but the slower the speed will cause the banknotes to hit the bottom of the blade. The speed of the receiving wheel is related to the counting speed and the number of the blades of the receiving wheel.
2. Iron frame
The whole frame adopts the punching pressure side plate, and the effect is proved to be better in practice. The advantage of this design is that the relatively high-precision parts of the left and right panels of the frame can be processed at one time using the same mold, which improves the assembly accuracy of the frame and also provides effective recognition of the banknotes in motion. The required positioning accuracy.
3.Control circuit part（Money counter）
A single-chip microcomputer control system is composed of the main control part, sensor signal amplifying and processing circuit, driving components, etc., and the magnetic and counting signals are introduced into the main controller through multiple interfaces. When banknotes are counted normally, each sensor collects signals for statistical sampling, identification, and deposits them as the basis for detection. When banknotes are counted, the signal parameters collected by each channel interface are compared and judged with the originally registered signal parameters. If there is an obvious difference, an alarm signal will be sent immediately, the motor will be stopped, and the corresponding signal prompt will be sent at the same time.
4. Sensor part
Recognition is to distinguish between true and false by detecting the inherent characteristics of the renminbi. The money counter is a mechatronic product, involving knowledge in many fields such as mechanics, electricity, optics, and magnetism, and requires coordination and cooperation from all aspects. The sensors of the deli model mainly consist of counting sensors and magnetic sensors.
