Abstract
The invention discloses a roller static electricity eliminating mechanism for a ticket reader, which comprises conductive rubber, wherein one end of the conductive rubber is connected with the side surface of a metal roller, and the other end of the conductive rubber is fixed on a hardware shell of the ticket reader. The contact point between the conductive rubber and the metal roller is positioned at the circle center of the side surface of the metal roller. The roller static eliminating mechanism for the ticket reading machine can effectively prevent the interference of lottery ticket surface scanning data caused by static electricity and the damage of a chip caused by static breakdown through the effective static electricity releasing loop design of the conductive rubber, the hardware shell and the grounding wire, greatly prolongs the service life of a product, and reduces the reject ratio of the product in operation.
Description
Technical Field
The invention relates to the field of lottery ticket reading machines, in particular to an electrostatic elimination mechanism with an easily replaceable structure.
Background
The special ticket reading machine for the lottery ticket is widely applied to a computer lottery ticket terminal, mainly used for scanning and identifying the lottery ticket or the lottery ticket and is a necessary part of the computer lottery ticket terminal.
The ticket reader controls the lottery ticket to pass through the CIS scanning head at a constant speed through the transmission mechanism, and the scanning of the lottery ticket is completed by the scanning head. Static electricity can be accumulated due to friction in the rotating process of the transmission mechanism, and when the accumulated static electricity is too large, the electric parts of the ticket reader can be damaged.
Because the ticket reading machine has high use strength and high ticket face value of the lottery, if the problems of hardware damage, ticket face data interference and the like occur due to electrostatic damage in the process, the customer loss can be caused, even serious problems of legal dispute and the like are generated, and therefore, the static electricity is eliminated to ensure the anti-interference performance and the reliability, and the special ticket reading machine for the lottery is the design key point.
The two ends of a metal rolling shaft in the conventional ticket reader are matched by using plastic bearings, static electricity cannot be thoroughly released due to no conductive action, and after certain strength is accumulated, the two ends of the rolling shaft and metal of a shell generate an electrostatic discharge phenomenon, so that the electrostatic discharge voltage is very high, and ticket face data can be mistaken when the ticket reader scans; meanwhile, after static electricity continuously impacts circuit board elements and damages are accumulated to a certain degree, the probability of damage to the internal circuit of the chip is very high.
Disclosure of Invention
The invention aims to provide a roller static electricity eliminating mechanism for a ticket reader, which effectively solves the problems of data interference, high damage rate of hardware due to static electricity impact and the like when the current ticket scanning surface is scanned.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
the utility model provides a read ticket machine roller bearing electrostatic elimination mechanism, includes conductive rubber, conductive rubber one end links to each other with the side of metal roller bearing, conductive rubber's the other end is fixed on the five metals shell of reading the ticket machine.
The contact point between the conductive rubber and the metal roller is located at the circle center of the side face of the metal roller.
The conductive rubber is fixed on a hardware shell of the ticket reading machine through a fixing screw.
The hardware shell is connected with the metal case shell.
The metal chassis shell is connected with a power supply ground wire through a ground wire.
The grounding wire is fixed on the metal chassis shell through a grounding screw.
Wherein, a rubber roller is sleeved on the metal rolling shaft; and plastic bearings are arranged at two ends of the metal rolling shaft.
Compared with the prior art, the invention has the outstanding effects that:
the roller static eliminating mechanism for the ticket reading machine can effectively prevent the interference of lottery ticket surface scanning data caused by static electricity and the damage of a chip caused by static breakdown through the effective static electricity releasing loop design of the conductive rubber, the hardware shell and the grounding wire, greatly prolongs the service life of a product, and reduces the reject ratio of the product in operation. The ticket reader adopting the roller static electricity eliminating mechanism can be used for lottery tickets (thermal paper printing) and can also be used for reading standard filling tickets (such as lottery ticket betting tickets or examination machine reading cards and the like).
At present, the ticket reader in the whole lottery industry has no static electricity eliminating device, so that electronic devices in a certain proportion are poor, and the reject ratio of the ticket reader can be greatly reduced after the mechanism is used.
The roller static electricity eliminating mechanism for the ticket reader is further described by the following description and specific embodiments in combination with the attached drawings.
Drawings
FIG. 1 is a schematic structural view of a roller static electricity eliminating mechanism for a ticket reader.
Detailed Description
As shown in figure 1, the roller static electricity eliminating mechanism for the ticket reading machine comprises conductive rubber 1, wherein one end of the conductive rubber 1 is connected with the side face of a metal roller 2, and the other end of the conductive rubber 1 is fixed on a hardware shell 7 of the ticket reading machine.
The contact point 5 between the conductive rubber 1 and the metal roller 2 is located at the center of the side of the metal roller 2. The contact point is slightly in interference fit, so that the position deviation in the operation process can be prevented.
The conductive rubber 1 is fixed on a hardware shell 7 of the ticket reading machine through a fixing screw 6. The hardware shell 7 is connected with the metal case shell. The metal chassis housing is connected to a power ground 9 via a ground line. The ground wire is fixed on the metal chassis shell through a ground screw 8.
A rubber roller 3 is sleeved on the metal roller 2; plastic bearings 4 are arranged at two ends of the metal roller 2.
The static electricity eliminating mechanism for the rolling shaft of the ticket reader can release static electricity generated by friction between the rolling shaft and paper to a grounding point in the ticket reading process of the ticket reader. The conductive rubber has good conductivity, and can effectively conduct away static electricity on the ticket reader roller. The contact point is located at the center of the side section of the roller, and the rolling displacement of the contact point is minimum, so that the possibility of friction damage is reduced. The contact point has good rebound size, and good contact performance is guaranteed after long-term use.
The static electricity eliminating mechanism is designed based on an easily replaceable structure, adopts a clamping structure, can be replaced outside, and is convenient to maintain when faults such as aging occur to the ticket reading machine. Based on the design of visual contact, can externally observe and judge its operating condition, can conveniently judge whether inefficacy.
The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solution of the present invention by those skilled in the art should fall within the protection scope defined by the claims of the present invention without departing from the spirit of the present invention.
