Abstract
A thermal printer rubber-roller mounting structure comprises a main frame and a rubber roller rotatably arranged on the main frame, two bearings arranged on two ends of the rubber roller and a groove arranged on the main frame and housing the bearings, characterized in that: a rod pressure mechanism for limiting the bearings in the groove and relieving the limit of the bearings after operation is arranged on the main frame. Compared with the prior art, the thermal printer rubber-roller mounting structure has the following advantages: at the work state, the bearings limited by the rod pressure mechanism can not move in the groove, the normal operation of the rubber roller is ensured and when the paper is fed, the bearings are quickly disengaged from the groove after operating the rod pressure mechanism, the whole operation is convenient, quick and simple.
Description
Technical field
The utility model relates to a kind of thermal printer, relates in particular to a kind of thermal printer rubber roll mounting structure.
Background technology
Existing thermal printer generally comprises body frame, motor, driving gear component, print head assembly and can be located at the rubber roll on the body frame rotationally; The active output gear engagement of the power intake of driving gear component and motor; Clutch end and the rubber roll gears engaged of being located at the rubber roll end, rubber roll is used to drive printing paper and moves, and has paper feed channel between rubber roll and the print head assembly; The rubber roll two ends are provided with two bearings, have the groove that supplies bearing to be provided with on the body frame.Generally, groove is a semi-circular shape.The bearing matching requirements have been satisfied in such design basically: the first, and the duty lower bearing is positioned at groove all the time; During paper, can easily rubber roll easily be thrown off in groove together with bearing on the needs.But exist following not enough: bearing play amplitude in groove is bigger, influences the normal operation of rubber roll.
The utility model content
The utility model technical problem to be solved is that the thermal printer rubber roll mounting structure that a kind of bearing can play in groove is provided to the above-mentioned state of the art.
The utility model another technical problem to be solved is to provide a kind of assembling to throw off conveniently thermal printer rubber roll mounting structure to the above-mentioned state of the art.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of thermal printer rubber roll mounting structure; Comprise body frame and can be located at the rubber roll on the body frame rotationally; Aforementioned rubber roll two ends are provided with two bearings; Have the groove that supplies bearing to be provided with on the aforesaid body frame, it is characterized in that described body frame is provided with one and can bearing be limited in the groove and after the operation and can removes the spacing pressure lever mechanism of bearing.
As preferably, described pressure lever mechanism can comprise
Depression bar; Can be located on the described body frame rotationally; Two ends have first compressing tablet, second compressing tablet and at least one end respectively and have pressing tablet; Form one respectively near groove on this first compressing tablet and second compressing tablet and can bearing be limited in first draw-in groove and second draw-in groove in the groove, this pressing tablet is under the application of force effect, and aforesaid first draw-in groove and the releasing of second draw-in groove are spacing to bearing; And
Return unit forces aforesaid first compressing tablet and second compressing tablet to act on the bearing all the time.
Make things convenient for rapidly for making bearing break away from groove, described first draw-in groove, one side can make bearing eject the drive division of groove after forming an extruding.
As preferably, described pressing tablet one-body molded with second compressing tablet on.
Preferred following setting of return unit: also be provided with a supporting plate on the described body frame, described return unit is the back-moving spring of being located between supporting plate and the depression bar front end face.
Further, described body frame is positioned at the depression bar rear end face and has the limited block that is rotated further of restriction depression bar.
Compared with prior art, the advantage of the utility model is: under the duty, the restriction bearing of compression rod mechanism can not play in groove, guarantees that rubber roll normally moves; During last paper, can make bearing break away from groove rapidly after the operation pressure lever mechanism, and then make rubber roll break away from body frame, convenient and swift, integrated operation is simple.
Description of drawings
Fig. 1 is the example structure sketch map.
Fig. 2 is the embodiment exploded.
Fig. 3 is the structural representation behind the removal rubber roll among Fig. 1.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Like Fig. 1, Fig. 2 and shown in Figure 3; Thermal printer in the present embodiment comprises body frame 1, motor 2, rubber roll 3 and printhead 4; Body frame 1 is provided with supporting plate 6 and pressure lever mechanism; Motor 2 through driving gear set (do not have among the figure and show) with transmission of power to the driving gear 31 of rubber roll, printhead 4 is located on the support 6 and near rubber roll 3.
Rubber roll 3 two ends are provided with two bearings 32, and body frame 1 has two side 11, have the groove 13 that supplies bearing 32 to be provided with on the sidewall 11, and pressure lever mechanism comprises depression bar 5 and return unit 7.
Further, body frame 1 is positioned at depression bar 5 rear end faces and has the limited block 12 that is rotated further of restriction depression bar.
Under the duty, the restriction bearing 32 that receives first draw-in groove 53 and second draw-in groove 55 can not play in groove 13, guarantees that rubber roll normally moves; During paper, force in pressing tablet 54 downwards and overcome return unit 7 elastic force on the needs, first draw-in groove 53 and second draw-in groove 55 are removed spacing, and simultaneously, drive division 56 acts on the bearing 32, bearing 32 moments in the groove 13 are ejected, and then make rubber roll 3 break away from body frames 1; Last paper continues to force in pressing tablet 54 after finishing, treat that bearing 32 is positioned in the groove after, unclamp pressing tablet 54, bearing 32 is just limited, convenient and swift like this, integrated operation is simple.
