Description
Technical field
This utility model relates to paper money counter technical field, particularly relates to a kind of bill counter magnetic head having and adding magnetic function.
Background technology
At present on domestic and international market, the magnetic head of paper money counter is to the knowledge of banknote magnetic otherwise:
(1) detection to banknote metal wire magnetic, generally uses a big magnetic head, and this big magnetic head is only to metal wire signal
There is output, crown word number magnetic and ink magnetic are not exported；
(2) to paper money number magnetic and the detection of ink magnetic, generally using the least a lot of magnetic head, this little magnetic head exists
Crown word number magnetic can be detected the when of not powered, but only could detect other printing ink signals powering up when, and magnetic
The voltage that head powers up, to different position printing ink signals, needs to add different voltage, uses different signals to amplify strategy.
The magnetic that adds of semiconducting-magnetic-head is to provide carrier deflection to quasiconductor in advance in the bottom of semiconductor indium antimonide at present
Magnetic field, Magnet one is scheduled on rearward away from position, R face inside magnetic head, and Magnet is usually the Magnet of one piece of blockage shape.Work as quasiconductor
Carrier causes the when of running into external magnetic field to produce magnetic field own and changes and make carrier deflect and change generation electric current
Change.
The big magnetic head of coil and the little magnetic head of existing use is all that the excursion according to the frequency of signal own is different to be employed
Different structures.Big magnetic head uses the metal wire magnetic that double slit design anti-interference detection frequency ratio is relatively low, and little magnetic head uses single
Small-gap suture design carry out the more higher ink magnetic of frequency acquisition.The feature of this two classes magnetic head is all that requirement bank note itself wants pre-
The probability producing signal output first just can be had already provided with magnetic.So it is the most necessary on the runway that paper money counter is before bank note is checked
Give the magnetic that the bank note abundance of process is enough in advance.A magnetic can also be produced at magnetic head R face by the method powered up to magnetic head
, but the signal of bank note one side can only be run out of, bank note turn-over signal the most just without, and voltage range is narrow the highest
A bit (30V) magnetic head is just saturated, and magnetic head is electrified for a long time generation heat, has a strong impact on head life.
The external coil type produced adds magnetic magnetic head and also uses the mode adding magnetic to make in addition to expensive at magnetic head R face
Coil, because outside changes of magnetic field produces signal, puts a piece of Magnet above a single magnet passage.Table at heads contact bank note
Face (R face) only has Magnet to be exposed, and the iron core of magnetic head itself is ensconced below Magnet.Principle is that magnetic field of magnets occurs above
The when of change, magnetic field is transmitted to following iron core gap and produces change, then the coil by the 2 groups of series aiding connections being wound on magnetic core
Produce signal.Feature can run out of all bank note signals simultaneously.Shortcoming is that the concordance feature of signal itself is unstable, signal height
The drift of some interval is very big, and paper money counter is easily reported by mistake.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of have the paper money counter magnetic adding magnetic function
Head.
The technical solution adopted in the utility model is:
A kind of have the bill counter magnetic head adding magnetic function, and it includes shell, and shell is provided with opening, shell along its length
Opening in be provided with least one set and extend the magnetic core of opening, described magnetic core includes a piece of SMIS sheet and the two of SMIS sheet
Side is arranged with magnetic seam copper coin, limit chip board, flat thin magnet and shielding sheet, the polarity of described flat thin magnet fitted the most successively
It is perpendicular to magnetic head R face, and the flat thin magnet of SMIS sheet both sides has identical polar orientation, and described limit chip board is arranged with
Coil windings, the upper and lower end face bearing of trend that axis bearing of trend is edgewise chip board of described coil windings, SMIS sheet two
The coil windings reverse parallel connection of side.
Described shell is cabinet.
The integral multiple that sheet number is 2 of described flat thin magnet.
The upper end of described shielding sheet is extended the part of cabinet and is fitted in magnetic head R face.
Described shell both sides are additionally provided with the screw extending in shell, and sheet is close to shield in described screw termination, and will shielding
Sheet, flat thin magnet, limit chip board, magnetic seam copper coin, SMIS sheet are bonded to each other closely.
This utility model also includes that wiring board, described wiring board include amplifying circuit and AD sample circuit, described wiring board
Being positioned at the inner chamber of shell, magnetic head signal waveform is amplified by amplifying circuit, and AD sample circuit is put the output of amplifying circuit
Magnetic head signal waveform after great carries out AD sampling, and AD sample circuit is provided with standard plug-in unit interface by wiring board and winding displacement is external
Output.
This utility model uses above technical scheme, establishes one at surface (R face) place that magnetic head contacts with bank note surely
Fixed magnetic field is interval, when outer synchronous signal is come in when, the magnetic field having built up at magnetic head R face is occurred disturbance, thus
In the respective coil windings in magnetic head SMIS sheet both sides, produce the induced signal of synchronization, due to coil windings be reverse parallel connection just
Induced signal is cancelled out each other and has played jamproof effect.Have built up at magnetic head R face when asynchronous signal is come in when
Magnetic field occur the order of disturbance different, thus produce nonsynchronous sense in the respective coil windings in magnetic head SMIS sheet both sides
Induction signal, owing to coil is still to have output after just induced signal being subtracted each other of reverse parallel connection.This utility model and former magnetic head
Except for the difference that being the remanent magnetism by banknote itself before to make magnetic head produce signal, this utility model has leaned on magnetic particle to magnetic head
The magnetic interference set up produces signal.When this utility model carries out currency examination, banknote need not to magnetize again and sensitivity significantly carries
High.
