Description
Technical field
The utility model relates to finance device field, particularly relates to a kind of paper money thickness testing apparatus preventing Thickness sensitivity parts from trembling.
Background technology
Paper money discrimination is the critical function of finance device, and wherein banknote thickness detection is the pith of paper money discrimination.The scheme that current industry is commonly used is: fixed base fiducial axis and Thickness sensitivity parts are formed thickness detection apparatus, the shell fragment of Thickness sensitivity parts forms elastic floating to engaged wheel and displacement detecting element and supports, when bank note passes through the gap of fixed base fiducial axis and engaged wheel, bank note is by Thickness sensitivity parts jack-up and displacement detecting element is subjected to displacement, and judges that whether the banknote thickness passed through is up to specification by the data of displacement monitoring detecting element change in location.In perfect condition, when bank note passes through, Thickness sensitivity parts are by jack-up, and bank note drives whole Thickness sensitivity parts to automatically reset by the shell fragment of rear elastic floating supporting role.But when actual motion, because shell fragment is that one end is fixed in frame, shell fragment is from jack-up to complete reseting procedure, the to-and-fro movement of upper frequency can be produced, cause trembling of displacement detecting element, highly sensitive due to displacement detecting sensor, slight trembling also can affect the accuracy of testing result.
Utility model content
The Thickness sensitivity parts that the utility model overcomes paper money thickness testing apparatus of the prior art affect the shortcoming of testing result accuracy because self tremble, and provide a kind of paper money thickness testing apparatus preventing Thickness sensitivity parts from trembling.
The technical scheme that the utility model realizes goal of the invention employing is: a kind of paper money thickness testing apparatus preventing Thickness sensitivity parts from trembling, comprise frame, the Thickness sensitivity parts of fixed base fiducial axis and one group of elastic floating, Thickness sensitivity parts comprise: engaged wheel, driven shaft, shell fragment and displacement detecting element, shell fragment one end connects with frame, the shell fragment other end is provided with engaged wheel and installs hanger, the engaged wheel that engaged wheel is arranged on shell fragment by driven shaft is installed on hanger, displacement detecting element is fixed on shell fragment, shell fragment forms elastic floating to engaged wheel and displacement detecting element and supports, fixed base fiducial axis is arranged in frame, shell fragment is arranged in frame, paper money transmission channel is formed between engaged wheel and fixed base fiducial axis, also comprise elastic deformation pressing plate, described elastic deformation pressing plate is arranged in frame, elastic deformation pressing plate contacts with shell fragment upper surface and installs, form the structure that elastic deformation pressing plate makes the engaged wheel of Thickness sensitivity parts contact with fixed base fiducial axis elastic floating through shell fragment.
The beneficial effects of the utility model are: after bank note passes through, there is the elastic deformation pressing plate of self-recoverage deformability to the Unidirectional acting force of shell fragment applying one perpendicular to fixed base fiducial axis, the engaged wheel of Thickness sensitivity parts is made to continue the steady state (SS) keeping being close to fixed base fiducial axis, shell fragment is avoided to produce the to-and-fro movement of upper frequency, cause trembling of displacement detecting element, decrease the metrical error brought because of shell fragment slight oscillatory, ensure that the reliability of high sensitivity displacement detecting sensor testing result, improve accuracy of detection.
Below in conjunction with accompanying drawing and embodiment, the utility model will be further described.
Accompanying drawing explanation
Fig. 1 is structural representation one of the present utility model.
Fig. 2 is structural representation two of the present utility model.
In accompanying drawing, 1 for shell fragment, 1-1 be union end, 1-2 is that engaged wheel is installed that hanger, 2 is elastic deformation pressing plate, 2-1 is surface of contact, 3 is displacement detecting element, 4 is driven shaft, 5 is engaged wheel, 6 is fixed base fiducial axis, 7 is power wheel.
Embodiment
As shown in drawings, a kind of paper money thickness testing apparatus preventing Thickness sensitivity parts from trembling of the present embodiment, comprises the Thickness sensitivity parts of frame, fixed base fiducial axis 6 and one group of elastic floating.Thickness sensitivity parts comprise: engaged wheel 5, driven shaft 4, shell fragment 1 and displacement detecting element 3.Shell fragment 1 one end connects with frame, and union end 1-1 is provided with the fixed installation hole connected with frame.Shell fragment 1 other end is provided with engaged wheel and installs hanger 1-2.The engaged wheel that engaged wheel 5 is arranged on shell fragment 1 by driven shaft 4 is installed on hanger 1-2.Displacement detecting element 3 is fixed on shell fragment 1.Shell fragment 1 pair of engaged wheel 5 and displacement detecting element 3 form elastic floating and support.Fixed base fiducial axis 6 is arranged in frame, and shell fragment 1 is arranged in frame, forms paper money transmission channel between engaged wheel 5 and fixed base fiducial axis 6.Also comprise elastic deformation pressing plate 2, described elastic deformation pressing plate 2 is arranged in frame, and elastic deformation pressing plate 2 has a surface of contact 2-1 be close to shell fragment 1.Elastic deformation pressing plate 2 contacts with shell fragment 1 upper surface and installs, and forms the structure that elastic deformation pressing plate 2 makes the engaged wheel 5 of Thickness sensitivity parts contact with fixed base fiducial axis 6 elastic floating through shell fragment 1.The preferred elastic deformation pressing plate 2 of the present embodiment is rubber pressing plate.
During actual use, power wheel 7 drives fixed base fiducial axis 6 to rotate.Bank note by during gap between fixed base fiducial axis 6 and engaged wheel 5 by Thickness sensitivity parts jack-up, corresponding displacement detecting element 3 is subjected to displacement, displacement detecting sensor is positioned on rack-mounted pcb board, the change in location of displacement monitoring detecting element 3, analyzed the movement range of Thickness sensitivity parts by the position variation signal obtaining displacement detecting element 3, thus detect by the thickness data of bank note.In shell fragment 1 jack-up process, there is deformation in the elastic deformation pressing plate 2 contacted with shell fragment 1.After bank note passes through, the shell fragment 1 playing elastic floating supporting role drives whole Thickness sensitivity parts to automatically reset.Now, elastic deformation pressing plate 2 deformation with self-recoverage deformability resets, the surface of contact 2-1 of elastic deformation pressing plate 2 is close to shell fragment 1, one is applied perpendicular to the acting force of fixed base fiducial axis 6 to shell fragment 1, the engaged wheel 5 of Thickness sensitivity parts is made to continue the steady state (SS) keeping being close to fixed base fiducial axis 6, shell fragment 1 is avoided to produce the to-and-fro movement of upper frequency, cause trembling of displacement detecting element 3, decrease the metrical error brought because of shell fragment 1 slight oscillatory, ensure that the reliability of high sensitivity displacement detecting sensor testing result, improve accuracy of detection.
