Description
Technical field
The utility model relates to a kind of thermal head hold-down mechanism of bar-code label printer, belongs to the bar-code label printer technical field.
Background technology
Bar-code label printer need be pressed on thermal head and print on the rubber roll when printing operation, to guarantee that thermal head can reliably contact with carbon ribbon, guarantees print quality.The thermal head hold-down mechanism of existing bar-code label printer mostly is to adopt following structure: a rotating clamping shaft and be fixed on the compact heap on the clamping shaft drives the compact heap compressing and guarantees thermal head on the thermal head gripper shoe of thermal head and print rubber roll and compress being equipped with through rotating clamping shaft.The hold-down mechanism of this kind structure exists thrust can not regulate, influence the defective that thermal head and carbon ribbon reliably contact.
The utility model content
To the above-mentioned defective that exists in the prior art, the utility model provide a kind of thrust conveniently adjusted, compress reliable hold-down mechanism.
The utility model is realized through following technical scheme: a kind of bar-code label printer thermal head hold-down mechanism; Comprise that corresponding thermal head gripper shoe is arranged on rotating back shaft between the left and right side plate, is arranged at least one pressure adjustmenting mechanism on the said back shaft; Said back shaft is provided with through hole; Said pressure adjustmenting mechanism comprises support, traveller; Said traveller be provided with screw thread and with the adjusting nut of this threaded engagement, its screwed end is located in the through hole on the back shaft, on the traveller between back shaft and the adjusting nut, is provided with stage clip; The other end of traveller is provided with the slide block that can oppress on the thermal head gripper shoe, and traveller is connected with back shaft through said support.
When the utility model compresses, drive pressure adjustmenting mechanism through rotation support shaft and rotate the slide block compressing that will be arranged on the traveller on the thermal head gripper shoe, the effect of the spring force of stage clip realization compressing down the thermal head gripper shoe.The adjustment of thrust size is regulated the spring force of stage clip and is realized through the adjusting nut on the adjustment traveller.
In order to prevent that traveller from deviating from, said traveller is provided with spacer pin.
Pressure adjustmenting mechanism in the utility model can be provided with one or more sets, but considers the simple and reliability of structural design, and said pressure adjustmenting mechanism is two that are provided with at interval.
The right-hand member of said back shaft is provided with connected spanner, can compress or unclamp hold-down mechanism easily through rotating spanner.
The utility model is simple in structure, its through simply, pressure adjustmenting mechanism design cleverly, effectively guaranteed hold-down mechanism to reliably the compressing of thermal head, and realized the adjusting of thrust making the thrust of thermal head adjustable through the spring force of adjustment stage clip; In addition, the design of the pressure adjustmenting mechanism of the utility model makes thrust easy to adjust, quick.

The specific embodiment
Below in conjunction with accompanying drawing and non-limiting embodiment the utility model is further described:
Shown in accompanying drawing 1-3; A kind of bar-code label printer thermal head hold-down mechanism; It comprises and is arranged on the rotating back shaft 8 between left plate 6 and the right plate 2 and is arranged on the pressure adjustmenting mechanism 7 on the back shaft 8; The two ends of back shaft 8 are supported by left plate 6 and right plate 2 respectively, and wherein, the part that the right-hand member of back shaft 8 passes right plate 2 is connected with spanner 3.Back shaft 8 is arranged on the top of thermal head gripper shoe 9.
Shown in accompanying drawing 4-7, on back shaft 8, be provided with through hole 17, described pressure adjustmenting mechanism 7 comprises support 11, traveller 14.Traveller 14 is provided with screw thread and is provided with the adjusting nut 13 with this threaded engagement; Traveller 14 screwed ends are located in the through hole 17 on the back shaft 8; On the traveller 14 between back shaft 8 and the adjusting nut 13, be provided with stage clip 12; The other end of traveller 14 is provided with slide block 15, and slide block 15 is a nylon material, and it can be oppressed on thermal head gripper shoe 9.Support 11 is a U type structure, and a side of support 11 is fixed on the back shaft 8, and traveller 14 is connected with back shaft 8 through support 11, slides up and down in the through hole that traveller 14 can have at another side of support 11.In order to prevent that traveller 14 from deviating from, also be provided with spacer pin 16 in the bottom of traveller 14.
In the present embodiment, be provided with two groups of pressure adjustmenting mechanisms on the back shaft, as required, pressure adjustmenting mechanism also can be provided with one or more groups.
During the utility model work; Pull spanner 3 and drive back shaft 8 rotations; Thereby the pressure adjustmenting mechanism 7 that drives on the back shaft 8 rotates; The slide block 15 that is arranged on traveller 14 ends is contacted with thermal head gripper shoe 9, and traveller 14 moves along its axis, and is pressed on the thermal head gripper shoe 9 at the effect sliding block 15 of the spring force of stage clip 12.Reverse rotation spanner 3 can unclamp pressure adjustmenting mechanism.When needs adjustment thrust big or small, rotate the size of adjusting nut 13 through regulating spring power and reach the adjusting purpose.
