Abstract
The utility model discloses a rubber roller component mounting structure. The rubber roller component mounting structure comprises a main frame and a rubber roller component which is arranged on the main frame, and is characterized in that: the rubber roller component comprises a rubber roller and a mounting plate for arranging the rubber roller; the two ends of the mounting plate are elastically provided with clamping blocks; and accordingly, the two sides of the main frame are provided with clamping grooves in which the clamping blocks are clamped and matched. The utility model also discloses a thermo-sensitive printer with the mounting structure. Compared with the prior art, the utility model has the advantages that: the clamping blocks and the clamping grooves are quickly and accurately arranged in one step; the structure is simple and practical; mounting deviation of the rubber roller component is avoided; and thus, paper is stably and reliably released and paper printing quality is guaranteed.
Description
Technical field
The utility model relates to a kind of rubber roll component installation structure, and the utility model also relates to a kind of thermal printer with this rubber roll component installation structure.
Background technology
Thermal printer commonly used, because the rubber roll assembly is provided with the error that has of position and anticipation on body frame, there is skew, the result causes, thickness is during greater than the printing operation of the higher printing paper of 0.15MM or hardness ratio, can cause that print quality is low to printing paper flexural deformation, paper fluctuation of service, reliable.
In addition, thermal printing movement in the past has two kinds of compound modes: a kind ofly be made up of overall plastic glue body frame, motor, gear train, rubber roll assembly (rubber roll+rubber roll stage clip), print components and spring pressuring plate, because spring pressuring plate and printing head support part all are positioned on the plastic cement body frame, its plastic cement body frame is easy to wear, and service life is shorter; The another kind of body frame of making for the all-metal foundry goods (comprise gear cap etc. also be metal casting), though advantage not easy to wear, long service life that this metal body frame has, but its manufacturing cost is higher, makes the whole cost of movement improve, and metal body frame having relatively high expectations to mould and die accuracy.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of rubber roll assembly to install accurately at the above-mentioned state of the art, is difficult for diastrophic rubber roll component installation structure in the printing paper print procedure.
Another technical problem to be solved in the utility model provides a kind of rubber roll assembly and installs accurately, is difficult for diastrophic thermal printer in the printing paper print procedure.
Another technical problem to be solved in the utility model is the movement long and lower thermal printer of cost in service life.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of rubber roll component installation structure, comprise body frame and be located at rubber roll assembly on the body frame, it is characterized in that described rubber roll assembly comprises rubber roll and is used to be provided with the installing plate of rubber roll, these installing plate two ends flexibly are provided with clamping block, accordingly, described body frame both sides have the draw-in groove that cooperates for aforementioned clamping block clamping.
Further, be convenient to accurate positioning, described rubber roll two ends are provided with top roller bearing, and accordingly, described body frame has the bearing groove of installing for aforementioned top roller bearing.
A kind of thermal printer, comprise body frame, motor, driving gear component and be located at rubber roll assembly and print head assembly on the body frame, the active output gear engagement of the power intake of driving gear component and motor, the rubber roll gears engaged of clutch end and rubber roll assembly, it is characterized in that described rubber roll assembly comprises rubber roll and is used to be provided with the installing plate of rubber roll, these installing plate two ends flexibly are provided with clamping block, accordingly, described body frame both sides have the draw-in groove that cooperates for aforementioned clamping block clamping.
Be convenient to production and assembly, described body frame one side is positioned at the driving gear component outside and is provided with a gear cap, and this gear cap inwall forms the sprocket of installing for described driving gear component.
The mounting structure of printhead and body frame is preferably as follows design: described body frame comprises the pedestal of plastic material and is fixed in shell fragment support on the pedestal that described print head assembly then is installed on this shell fragment support.Described print head assembly two ends have boss, accordingly, form the adaptive groove for aforementioned boss plug-in mounting on the described shell fragment support.Plastic material can make manufacturing cost reduce.
Compared with prior art, advantage of the present utility model is: clamping block and draw-in groove are installed quick and precisely, settle at one go, and use simple in structure can not cause the installation deviation of rubber roll assembly, makes paper delivery reliable and stable, guarantees the paper print quality.
