Axis-split type paper money thickness-measuring mechanism

Abstract

The invention discloses an axis-split type paper money thickness-measuring mechanism. The mechanism comprises a thickness-measuring rack, the thickness-measuring rack is provided with a plurality of rocker arm brackets arranged along the width direction, each rocker arm bracket is provided with an independent rocker arm rotating shaft, the rocker arm rotating shaft is connected with a rocker arm in a rotating manner, the rocker arm is provided with a roller whose axis direction is parallel to the axis direction of the rocker arm rotating shaft, the roller comprises double coaxial wheels arranged at two sides of the rocker arm, a cylindrical surface of the roller is attached to a roller surface of a bearing roller below, one side surface of the rocker arm bracket, parallel to the roller axis, is provided with a positioning pin and a threaded hole, the thickness-measuring rack is provided with a positioning hole plugged with the positioning pin in tight fit and a bolt connection through hole corresponding to the threaded hole, a bolt penetrates through the bolt connection through hole and is threadingly connected with the threaded hole, and a fit gap used for adjusting the position is reserved between external threads of the bolt and the bolt connection through hole. The beneficial effects of the mechanism are that good measuring precision is realized no matter a single-wheel roller or a double-wheel roller rolls over the paper money, and the dedusting effect is good so that the measuring precision is guaranteed.

Description

technical field [0001] The invention belongs to the field of machinery, in particular to a shaft-splitting banknote thickness measuring mechanism. Background technique [0002] With the continuous development of the financial industry and related technologies, more and more banknote deposit and withdrawal modules need to have authentication requirements. The traditional thickness measuring mechanism only measures the thickness of single or double channels, and cannot measure the thickness of banknotes or paper in the entire range. It is difficult to detect tapes, folded edges, and local damage. Therefore, more and more manufacturers Apply the full-coverage thickness measuring mechanism to the banknote authentication module. Chinese patent document CN203837677U disclosed a "thickness detection device" on September 17, 2014, including a figure-eight plate, a thickness-measuring base plate, and a rotating shaft. The rotating shaft can rotate relative to the thickness-measuring...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved in the present invention is that the existing banknote thickness measuring mechanism is limited by the manufacturing accuracy, resulting in low thickness measurement accuracy, it is difficult to ensure the measurement accuracy when only one side wheel rolls over the banknote surface, and the dust removal effect is not ideal at the same time , has an impact on the measurement accuracy, thus providing a split-axis banknote thickness measurement mechanism, which has good measurement accuracy regardless of whether single or double wheels roll over banknotes, and has a good dust removal effect to ensure measurement accuracy
