Description
Technical field
The present invention relates to the drives structure of stylus printing pin, specifically with the print needle drives structure of oil storage tank.
Background technology
Impact printer still serves some special industries because of it relative to the otherness of ink-jet, laser printer uniqueness.Print needle on impact printer goes out pin and narrowing action is the key correctly printed.With reference to described in Fig. 1, the print needle drive unit of needle type print head comprises the yoke 1 of U-shaped structure, the upper surface of the first foot 11 of yoke 1 is provided with the fulcrum support plate 2 be made up of magnetic material, second foot 12 of yoke 1 is wound with coil 3, this coil 3 is connected with power supply, the top position of described yoke 1 is provided with armature 4, one end of armature 4 is extended with the first leg 41 and this first leg 41 is provided with the first pivoting point 5, the other end of armature 4 connects print needle 6, described armature 4 is also provided with second leg 42 corresponding with the second foot 12 of yoke 1, armature 4 between the second leg 42 and print needle 6 is provided with reseting pressuring spring 7, its operation principle is as follows: after printer receives type information, coil 3 is energized, thus magnetic circuit is produced in yoke 1 and armature 4, and then the second leg 42 bottom and abutting with the second foot 12 of yoke 1 under the drive of magnetic force, thus drive print needle 6 to go out pin, during narrowing, coil 3 power-off, the second leg 42 of armature 4 loses the suction-operated of magnetic force, armature under the effect of reseting pressuring spring 7 on pendulum, realize narrowing.But in this structure, because armature swings around the first pivoting point 5, therefore contact friction is certainly existed in the first pivoting point position, particularly print needle go out pin with narrowing number of times frequent, its wearing and tearing are more frequent, the drive unit of general stylus printing pin can allow print needle to go out pin 2 ~ 300,000,000 times, after reaching this number of times, the serious wear of the first pivoting point position, easily to print needle go out pin and narrowing produces a very large impact, thus it is stable not to cause print needle to go out needle force degree, and then affect print quality, so must change corresponding component.For some special industries, because printing amount is comparatively large, therefore just may needs to change associated components frequently, thus bring certain inconvenience to user, and too increase the maintain and replace cost of user.Therefore, need to improve further and optimize to the structure of the print needle drive unit of the needle type print head in conventional art.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of print needle drives structure with oil storage tank, it effectively reduces wearing and tearing, and what improve print needle goes out pin number of times, decreases client's replacement frequency, reduces the maintenance cost of user.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of print needle drives structure with oil storage tank, comprise the yoke of U-shaped structure, the upper surface of the first foot of yoke is provided with the fulcrum support plate that magnetic material is made, second foot of yoke is wound with coil, this coil is connected with power supply, the top position of described yoke is provided with armature, one end of armature is extended with the first leg and this first leg is provided with the first pivoting point, the other end of armature connects print needle, described armature is also provided with second leg corresponding with the second foot of yoke, armature between the second leg and print needle is provided with reseting pressuring spring, described first pivoting point and fulcrum support plate hinged, first foot of described yoke is provided with oil storage tank, described oil storage tank is covered by fulcrum support plate, oil in oil storage tank utilizes capillarity and surface tension effects and is slowly supplied to described first pivoting point position, described fulcrum support plate is provided with the groove of the first leg of stepping down.
As the improvement of technique scheme, described oil storage tank is two, is arranged in two side positions of armature.
The invention has the beneficial effects as follows: the present invention adopting said structure, by by the first pivoting point and fulcrum support plate hinged, first foot of yoke is provided with oil storage tank, oil storage tank is covered by fulcrum support plate, utilize capillarity and surface tension effects that the oil in oil storage tank is supplied to described first pivoting point position slowly, ensure that oil is supplied to the first pivoting point position and realizes lubrication, reduce the wearing and tearing of the first pivoting point position greatly, the pin number of times that of print needle is made to bring up to 4 ~ 600,000,000 times from original 2 ~ 300,000,000 times, what improve print needle greatly goes out pin number of times, user is made no longer to need to change associated components frequently, effectively reduce user's maintain and replace cost, and the present invention is simple and reasonable compact, easy for installation, implement simple, cost is low, can be applicable on various needle type print head.
