Currency detector for finance

Abstract

The invention provides a currency detector for finance. The currency detector comprises a shell, a first motor, a second motor, a currency catching wheel and a driving wheel and further comprises a first heat conducting part, a second heat conducting part, a first heat dissipation mechanism and a second heat dissipation; the first heat dissipation mechanism and the second heat dissipation mechanism each comprises a semiconductor chilling plate and a cooling fin, the semiconductor chilling plate of the first heat dissipation mechanism is installed on the back side wall of the shell, the semiconductor chilling plate of the second heat dissipation mechanism is installed on the left side wall of the shell, the cold faces of the semiconductor chilling plates of the first heat dissipation mechanism and the second heat dissipation mechanism are both located in the shell, and the hot faces of the semiconductor chilling plates of the first heat dissipation mechanism and the second heat dissipation mechanism are both located outside the shell; and the cooling fin of the first heat dissipation mechanism is installed on the hot face of the semiconductor chilling plate of the first heat dissipation mechanism. According to the currency detector, the heat dissipation performance is improved, the probability that the motors are burned out is decreased, and both the safety level and the dust prevention level are increased.

Description

technical field [0001] The invention relates to the field of financial equipment, in particular to a banknote detector used for finance. Background technique [0002] A banknote detector is a machine that verifies the authenticity of banknotes and counts the number of banknotes. Due to the large scale of cash circulation and the heavy cash handling work at the cashier counter of the bank / financial department, the money counter has become an indispensable equipment. It integrates counting and counterfeiting. With the development of printing technology, copying technology and electronic scanning technology, the production level of counterfeit banknotes is getting higher and higher. It is necessary to continuously improve the counterfeiting performance of the banknote counter. According to the different trajectory of the banknotes, the banknote counters are divided into horizontal and vertical banknote counters. There are usually three ways of identifying counterfeit: fluores...

AI Technical Summary

Problems solved by technology

The two motors will generate a lot of heat during high-speed operation, and the heat will slowly diffuse out through the side wall cooling vents. However, due to continuous operation, a large amount of heat will be concentrated at the two motors. Due to the use of natural heat dissipation, the heat cannot be dissipated in time. It is easy to burn out the motor

[0004] In addition, due to the cooling vents on the side wall, dust in the environment is easy to accumulate inside the banknote detector, and even sundries are easy to enter through the cooling vents

When the dust continues to accumulate, on the one hand, it will affect the heat dissipation performance, and on the other hand, it will affect the circuit board and cause a short circuit
