Abstract

The utility model relates to a magnetic head mechanism of automatic magnetic checking fake bank note counting machine, which comprises a bank note pressing strip shaft, a magnetic head and a pressing sheet, wherein, the bank note pressing strip shaft, the magnetic head and the pressing sheet are arranged on a bank note counting machine. The utility model is characterized in that the pressing sheet is composed of a leather sheet and a metal sheet; the leather sheet is fixedly connected with the lower part of the metal sheet; the metal sheet is fixedly connected with the upper side of the bank note pressing strip shaft. The utility model has the advantages the leather sheet combines with the metal sheet, which can make the leather sheet can not deform for a long time, and meanwhile abrasion is small, and the surface of the magnetic head can contact with the face of the bank note thoroughly; the existence of a magnetic signal can be detected exactly; thus, miss alarm phenomena can not occur when the whole machine performance detects fate bank note.

Description

The head mechanism of automatic fake-bank-note-checking paper money counter

The utility model belongs to the magnetic head structure of the pseudo-paper money counter of a kind of two inspections, particularly a kind of head mechanism of automatic fake-bank-note-checking paper money counter.

At present each specialized bank is in order to improve when the counting distinguishing ability to counterfeit money, generally use the pseudo-paper money counter counting of two inspections, but the magnetic head structure that the general pseudo-paper money counter of two inspections adopts is to be made of plastic sheet and passive pinch roller, or head surface does not have mechanism, responds to by the circuit amplification quantity.There are the following problems for the existing magnetic head structure: use plastic sheet, and not wear-resisting, and be easy to generate static, be difficult to adapt to the tolerance of this structure; Passive pinch roller is to be pressed on the head surface a bit or a horizontal line, and the banknote nominal value is contacted fully with head surface, so it is poor to get magnetic signal, misoperation is many; Head surface does not have mechanism, comes the effect of induced signal to be by increasing the circuit amplification quantity, and counterfeit money has been gone over to induction by the drift voltage of circuit often, makes that whirlpool newspaper rate is higher, influences the complete machine performance.

The purpose of this utility model provides a kind of head mechanism of automatic fake-bank-note-checking paper money counter, and it is not yielding, wearing and tearing are little, electrostatic prevention, head surface fully contact with nominal value, and it is accurate to gather magnetic signal, and nothing is failed to report phenomenon.

The purpose of this utility model is to produce like this: it comprises press-note bar axle, magnetic head and the compressing tablet of paper money counter, its technical scheme main points are: compressing tablet is made of leather sheet and sheet metal, leather sheet is fixed in the bottom of sheet metal, and sheet metal is fixedly connected on the press-note bar axle.

Principle of work: when banknote when the gap is passed through between the leather sheet of head surface and compressing tablet, the magnetic ink of banknote nominal value makes it fully contact acquired signal with head surface by the soft stress of leather, when banknote is by magnetic head in batches simultaneously, fricative static imports underground (zero potential) by the sheet metal above the leather, has increased reliability.

The utility model has the advantages that: leather sheet and sheet metal combine, can make the leather sheet shape that remains unchanged for a long period of time, it is little to wear and tear simultaneously, and head surface can fully contact with the banknote nominal value, gather that magnetic signal " has " or " nothings " is accurate, guarantee that the complete machine performance can not produce to fail to report phenomenon when the detection counterfeit money.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model structural representation.

Fig. 2 is that the utility model is installed in the position view on the paper money counter.

See Fig. 1, concrete structure is as follows: flexibly connect press-note bar 2 on the press-note bar axle 4 on the paper money counter, coaxial upward also fixedly connected phosphorus bronze sheet 3, it is the compressing tablet part that phosphorus bronze sheet 3 is positioned at magnetic head 5 upper sections, the leather sheet 1 of bonding or riveted joint ox-hide material below the phosphorus bronze sheet 3 of compressing tablet part, the gap that has banknote to pass through between the lower surface of leather sheet 1 and the magnetic head 5, magnetic head is fixed on the paper money counter by support 6.See Fig. 2.The utility model is installed in the sth. made by twisting paper money wheel 8 of paper money counter and takes out position between the paper money wheel 7.

Claims

1, a kind of head mechanism of automatic fake-bank-note-checking paper money counter, it comprises press-note bar axle, magnetic head and the compressing tablet of paper money counter, and it is characterized in that: compressing tablet is made of leather sheet and sheet metal, and leather sheet is fixed in the bottom of sheet metal, and sheet metal is fixedly connected on the press-note bar axle.
