Floating mechanism of currency detection apparatus and currency detection apparatus

Abstract

The invention discloses a floating mechanism of a currency detection apparatus and a currency detection apparatus. The floating mechanism includes a rack (1), two shrapnels (2) and a floating shaft (3). The left and right ends of the floating shaft (3) are separately sleeved with a flange bearing (4). The rack (1) includes two supporting plates (11) which are parallel to each other and a fixing plate (12) which is disposed between the two supporting plates (11). The left end of the floating shaft (3) is installed on the corresponding supporting plate (11) through the corresponding flange bearing (4). One end of respective shrapnel (2) is fixed on the fixing plate (12), and the other end of respective shrapnel (2) abuts against one side of the corresponding flange bearing (4) approaching the fixing plate (12). The floating mechanism can work normally and stably. The currency detection apparatus includes a magnetic sensor (5) and the aforementioned floating mechanism. The floating shaft (3) is sleeved with a floating roller (6). One end of the floating shaft (3) is provided with a transmission belt pulley (7). The currency detection can acquire magnetic data of paper currency in a stable and reliable manner.

Description

technical field [0001] The invention belongs to the technical field of financial equipment, and in particular relates to a floating mechanism of a banknote checking device and a banknote checking device. Background technique [0002] In the existing financial recycling machine equipment, there is a banknote checking module. The banknote checking module has a banknote transfer channel, and there are rollers above and below the banknote transfer channel. In order to avoid paper money wear and tear, one of the rollers needs to be installed on the floating axis. There are scattered detection points arranged between the rollers. When the banknotes are driven by the rollers and pass through the scattered detection points, each detection point detects the designated position of the banknotes to judge whether it is a counterfeit banknote. When the position of the banknote in the channel deviates, it will affect the accuracy of detection. In addition, since there are many detectio...

Problems solved by technology

When the position of the banknote in the channel deviates, it will affect the accuracy of detection

In addition, since there are many detection points and different locations need to be installed, installation and maintenance are more difficult

[0003] The floating shaft of the existing banknote verification module uses a pair of torsion springs to ensure that the floating shaft slides up and down in the designed track groove; under normal circumstances, the bending arms of the left and right torsion springs act on the outside of the rib bearing, while In the actual working process of the banknote verification module, the bending arms of the torsion springs on both sides of the floating shaft may have a position away from the rib bearing, which means that the torsion spring structure realizes the floating effect of the floating shaft. At the position of the mechanism, the magnetic mechanism cannot accurately collect the magnetic information of the banknotes, and it will also cause the banknotes to be jammed at the position of the magnetic mechanism, which will cause equipment failure;

[0004] The contact between the torsion spring and the rib bearing is point contact, and the design of the bending arm is limited by the position of the rib of the rib bearing, so it should not be too long. There will be differences, which are reflected on the outside of the rib bearings on both sides of the floating shaft due to different force points, resulting in inconsistent elastic forces on the left and right sides of the floating shaft, and at this time the position of the action point of the torsion spring cannot be adjusted;

[0005] In addition, the torsion spring is easy to deform due to the wire diameter (generally designed to be 0.8-1mm), which is also a problem in the logistics link. It is necessary to strictly control the control, which will cause the cost of a single component to increase;

[0006] The left and right torsion springs have a symmetrical structure, that is, the left and right torsion springs are two parts and cannot be replaced. Two parts need to be managed, resulting in increased processing costs and maintenance costs
