Description
Technical field
The utility model is related to paper money counter technical field more particularly to it is a kind of have plus magnetic function bill counter magnetic head.
Background technology
At present semiconducting-magnetic-head plus magnetic be the bottom of semiconductor indium antimonide in advance to semiconductor provide carrier deflection
Magnetic field, magnet one are scheduled on inside magnetic head rearward far from the faces R position, and magnet is usually the magnet of one piece of blockage shape.Work as semiconductor
Carrier causes to generate variation to magnetic field itself and make carrier deflect and change generation electric current when encountering external magnetic field
Variation.
The existing big magnetic head of the coil used and small magnetic head are used according to the variation range difference of signal frequency itself
Different structures.Big magnetic head is magnetic using the relatively low metal wire of the anti-interference detection frequency of double slit designs, and small magnetic head is using single
Small―gap suture design to carry out the more higher ink of frequency acquisition magnetic.The characteristics of this two classes magnetic head is all that requirement bank note itself is pre-
First already provided with the magnetic possibility that can just have and generate signal output.So paper money counter is all necessary on the runway before bank note inspection
Give the bank note abundance passed through enough magnetism in advance.A magnetic can also be generated at the faces magnetic head R 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 is almost just without and voltage range is narrow slightly high
A bit（30V）Magnetic head is just saturated, and magnetic head is electrified for a long time generation heat, seriously affects head life.
The coil type of foreign countries' production adds magnetic magnetic head also to make by the way of adding magnetic at the faces magnetic head R other than expensive
Coil puts a piece of magnet because outside changes of magnetic field generates signal above one single magnet passage.In the table of heads contact bank note
Face（The faces R）Only magnet is exposed, and the iron core of magnetic head itself is ensconced below magnet.Principle is magnetic field of magnets generation above
Magnetic field is transmitted to following iron core gap and generates variation, then the coil by being wound on 2 groups of series aiding connections on magnetic core when variation
Generate signal.Feature can run out of all bank note signals simultaneously.The disadvantage is that the consistency feature of signal itself is unstable, signal height
The drift of point interval is very big, and paper money counter is easy wrong report.
Although the utility model patent for having patent No. ZL 201620588036.0 discloses and a kind of has plus magnetic function
Bill counter magnetic head, but in the technical solution " polarity of the flat thin magnet is perpendicular to the faces magnetic head R ", this feature is paper money counter application
Ideal case, the technical conditions require it is harsh, in actual production the associated components of bill counter magnetic head processing and installation essence
Degree often cannot be satisfied requirement, and the installation assembly of the corresponding counting machine equipment of the Patent Case is difficult, is extremely unfavorable for extensive
Production and application.
