1. Structure of the multi-function money detector:
The main body is composed of twisting, issuing, receiving, rack, electronic circuit, and transmission parts.
1. The twisting part
The main structure is the banknote sliding plate, the banknote feeding tongue, the resistance rubber, the banknote dropping plate, the adjusting screw, and the banknote twisting rubber ring. The banknote counting machine uses the continuous grading of the banknotes on the surface, and the function of the twisting rubber ring is to prevent the banknotes from overlapping and realize the separation. Due to friction, the twisting collar and resistance rubber wear more seriously. The solutions are: increase the outer diameter, open a groove in the middle of the outer ring, increase the wear resistance of the money-twisting rubber ring, increase the contact area of the rubber ring with the banknotes, improve the adhesion to the banknotes, and increase the service life.
2. Cash out part
The main body is composed of a banknote rubber wheel and a banknote counter-rotating wheel. +
3. The receiving part
It is composed of banknote claw wheel, banknote stripper and banknote stopper. Preventing banknotes from flying out: the determination of the central position of the banknote receiving impeller; the shape of the leaf claw; the speed of the impeller
4. Transmission part
Divided into single motor and dual motor drive.
5. Rack composition
Using the design of stamping edge plate, this design can improve the equipment accuracy of the frame and reduce the cost.
6. Electronic circuit part
There are main control parts, sensors, drive components, power supply and other parts to form a single-chip control system.
Second, the principle of the universal money detector
Identify the authenticity of banknotes by infrared, fluorescence, magnetism, laser and other methods.
Fluorescence detection: The essence is to detect paper. The renminbi is made of special paper, and the extra-long counterfeit currency will be bleached. The bleached counterfeit currency will undergo a fluorescent reaction when the paper is irradiated by ultraviolet rays, but the renminbi will not have a fluorescent reaction.
Magnetic detection: detect large denomination banknotes above 20 yuan. The magnetic analysis of the entries on the RMB is carried out through the circuit to identify the authenticity.
Infrared detection: Because of the special structure of RMB paper, it is relatively strong and has a high density. Therefore, the authenticity of the paper money can be distinguished by the intensity of the infrared absorption of the banknotes.
Anti-sandwich detection: distinguish banknotes of different denominations.
The invention of the universal money detector not only protects the interests of banks, but also combats those illegal people who print counterfeit money. It has maintained social peace in our country and is a rare device.
