Technical field
The utility model relates to the printer of a kind of printed tickets etc., relates in particular to a kind of printer that can use the print media of multiple different-thickness.
Background technology
Along with the application to printer is extensive day by day, adaptability to printer has proposed more and more higher requirement, and such as the medium of printing different-thickness, and common printer is because structural limitations, the minimum a kind of medium of thickness range can only be adapted to, current general demand can not be satisfied.
At present, the structure of common printer is such, the printer main body support is provided with printhead fixed axis and asessory shaft, printhead fixed axis and asessory shaft are separately fixed on the printer main body support, be fixed with printhead on the printhead fixed mount, also be provided with in the printhead relevant position and print rubber roll or liner (in the following description be example to print rubber roll); On support, also be provided with power set, drive printhead axially moving back and forth along printhead fixed axis and asessory shaft by the printhead fixed mount.In the printer of this kind structure, because printhead fixed axis and asessory shaft pass two circular holes of printhead fixed mount respectively, so printhead can't be done close or away from printing moving of rubber roll, making the distance between printhead and the rubber roll is fixed value.When using a kind of medium of thickness, can satisfy print media and just lean against on the rubber roll, like this, printhead also is a suitable numerical value to the distance of print media, printing effect is relatively good, and can guarantee the service life of printhead; Yet when printing the medium of other thickness, because distance is constant between printhead and the rubber roll, and the thickness of print media becomes big or diminishes, cause printhead can't remain on suitable numerical value to the distance of surface of print media, like this, just can not guarantee printing effect, the service life of also having reduced printhead simultaneously.
Summary of the invention
The utility model is exactly the problem that exists in the above-mentioned background technology, a kind of distance that can adjust easily between printhead and the rubber roll is provided, thereby guarantee the distance of printhead and surface of print media, guarantee printing effect, and guarantee the printhead printer in service life.
The utility model is to realize like this, it comprises main body rack and print head assembly, wherein print head assembly comprises printing rubber roll, printhead, printhead fixed mount, fixed axis and asessory shaft, wherein printhead is arranged on the printhead fixed mount, the printhead fixed mount is set on fixed axis and the asessory shaft, this fixed axis and asessory shaft two ends correspondence are connected on the main body rack, it is characterized in that the eccentric that on main body rack and print head assembly, is provided for adjusting printhead and prints the rubber roll spacing.
Described eccentric is eccentric handle, and its middle part is for having the cylinder of eccentric orfice, and top is handle, and the bottom is a locator protrusions; The fixed axis two ends are arranged in the eccentric orfice, and the middle part cylinder of eccentric handle embeds in the main body rack, and can relatively rotate, and the locator protrusions of corresponding eccentric handle is provided with locating slot on main body rack.Eccentric orfice is a semicircle orifice, and the end of fixed axis is corresponding with it.At least two installation nibs are set on the middle part cylinder of decenter clutch, and correspondence is provided with to install and uses hole clipping on the main body rack.Locating slot on the main body rack has a plurality of.Between printhead fixed mount and the asessory shaft lateral clearance is arranged.Be set on the printhead fixed mount on the asessory shaft, its axis hole is a strip, and asessory shaft also relative set is a strip.

The specific embodiment
Fig. 2 is the schematic diagram of the utility model printer main body support; In the both sides of printer main body support, be respectively arranged with first hole clipping 11 and second hole clipping 13, wherein, also be symmetrical arranged on first hole clipping 11 on fluted 12, the second hole clippings 13 and also be symmetrical arranged fluted 14; In the both sides of printer main body support, also be respectively arranged with the first asessory shaft fixing hole 15 and the second asessory shaft fixing hole 16; Below first hole clipping 11, be also to be provided with some locking grooves 19 on the circumferential position in the center of circle with the center of circle of first hole clipping 11.
Fig. 3 is the schematic diagram of the utility model first decenter clutch 2; First decenter clutch 2 has wrench body 21, and wrench body 21 is a cylindrical form, and wrench body 21 is provided with first flange 22, and the opposite side corresponding with first flange 22 is provided with retainer 26, and the end of retainer 26 is provided with retention tab 27; On wrench body 21, also be provided with first nib 24 and second nib 25; Also has first semicircle orifice 23 on the wrench body 21; As shown in Figure 4, first semicircle orifice 23 is non-concentric structure with wrench body 21, and promptly first semicircle orifice 23 has constituted eccentric wheel structure with wrench body 21; The structure of second decenter clutch 7 and first decenter clutch 2 are same or similar, and its core also is provided with semicircle orifice.
Fig. 5 is the schematic diagram of printer of the present utility model.First decenter clutch 2 and second decenter clutch 7 be rotatable respectively to be arranged on first hole clipping 11 and second hole clipping 13 of both sides of printer main body support 1; The two ends of printhead fixed axis 5 are semi-circular shape, semicircle orifice with first decenter clutch 2 and second decenter clutch 7 matches respectively, like this, printhead fixed axis 5 just can be fixed on the printer main body support 1 by first decenter clutch 2 and second decenter clutch 7; The two ends of asessory shaft 6 are separately fixed on the first asessory shaft fixing hole 15 and the second asessory shaft fixing hole 16; Printhead 4 is fixed on the printing head support part 3, and there is through hole 42 front portion of printing head support part 3, and also there is strip through-hole 41 at the rear portion; Printhead fixed axis 5 and asessory shaft 6 pass through hole 42 and strip through-hole 41 respectively, and printhead fixed mount 3 is supported.
In above-mentioned printer, because first decenter clutch 2 and second decenter clutch 7 are eccentric structure, the two ends of printhead fixed axis 5 are fixed on first decenter clutch 2 and second decenter clutch 7, so, when rotation first decenter clutch 2 and second decenter clutch 7, variation has taken place with respect to the position of printer main body support 1 is also corresponding in printhead fixed axis 5, do relative motion with respect to rubber roll or liner (not shown) thereby drive printhead 3, realized adjusting the purpose of distance between printhead 3 and rubber roll or the liner.
Match with retention tab 27 on first decenter clutch 2 at the locking groove on the printer main body support 1 19, can effectively make first decenter clutch 2 stop at certain fixing position, simultaneously, firmly pull the handle 29 on first decenter clutch, 2 tops, can make the retention tab 27 of first decenter clutch 2 break away from printer main body support 1 on the cooperating of locking groove 19, and first decenter clutch 2 is stopped at the position that another is fixed.By said structure, can make first decenter clutch 2 stable be fixed on a certain position, also can make it break away from this position, corresponding like this, printhead can be stable rests on a certain position, also can break away from this position and forward our needed another location to.
