Paper money thickness detection dust removal structure and money detection device

Abstract

The invention provides a paper money thickness detection dust removal structure and a money detection device. The paper money thickness detection dust removal structure comprises at least one arched dust removal block buckled on a thickness detection idler wheel or a thickness basic shaft, two dust removal portions arranged on the arched dust removal block and an elastic element used for providing elastic pushing force to the arched dust removal block, wherein each of the two dust removal portions comprises a cutting edge, the two cutting edges are respectively abutted against the thickness detection idler wheel or the thickness basic shaft, the dust removal block and the elastic element are connected in detachable mode, the elastic element is an elastic sheet, and a detachable connection of the dust removal block and the elastic element adopts a clamping structure. The money detection device adopts the paper money thickness detection dust removal structure. The paper money thickness detection dust removal structure and the money detection device are convenient to maintain and repair, simple in structure, and stable in dust removal effect, and greatly improve accuracy of detected money thickness detection.

Description

technical field [0001] The invention belongs to the technical field of cash processing equipment, and more specifically relates to a banknote thickness detection and dust removal structure and a banknote detection device using the banknote thickness detection and dust removal structure. Background technique [0002] In banknote cash processing equipment such as ATMs and sorting machines, detecting the thickness of banknotes is an important means to distinguish the authenticity of banknotes. The thickness of banknotes is detected by the thickness detection device of the banknote cash processing equipment. The accuracy of banknote thickness detection is not only affected by the processing precision of the thickness detection reference axis and the thickness detection roller itself, but also by other installation methods. Interference from foreign objects such as banknote dust and ink will have a serious impact on the accuracy and stability of thickness detection. In some exis...
