Description
Technical field
The utility model relates to a kind of roll shaft, particularly relates to a kind of card puncher roll shaft structure.
Background technology
Card puncher is a kind of printing device of type slug shape code on card; It is that roll shaft bottom the import by being arranged on printer drives the card be stacked and placed on above it to enter printer, by printhead and colour band, the bar code recorded in computer in advance is directly printed on card in printer again, make each card have a different bar code.In the process printed, roll shaft often rotates and a lowermost card once can be driven to enter in printer; But, card due to import department is overlapping often to be placed, when the quantity of card is more, the card being positioned at bottommost is subject to larger pressure and makes frictional force comparatively large, and the roll shaft surface of existing card puncher is in smooth, therefore, print process in often occur skid phenomenon and cannot by card send into or send into printer completely, thus cause print failure or print position inaccurate, have a strong impact on printing effect and the print quality of card puncher.
Utility model content
The purpose of this utility model is that providing one to enter card stablizes, and improves the card puncher roll shaft structure of printing effect and print quality.
To achieve these goals, the card puncher roll shaft structure that the utility model provides, comprise central shaft and roll shaft main body, described roll shaft main body is fixed on described central shaft coaxially, described central shaft is articulated on described card puncher import bottom surface, the side of described roll shaft main body is higher than the bottom surface of described card puncher import, the cambered surface of the sidewall of described roll shaft main body is provided with the first friction lines, the angle of the circular arc of the cambered surface at described first friction lines place is less than 180 degree, and described first friction lines extends to the two ends of described roll shaft main body along the central axis direction of described roll shaft main body.
Compared with prior art, because the utility model by being provided with the first friction lines in the cambered surface of the sidewall of described roll shaft main body, the angle of the circular arc of the cambered surface at described first friction lines place is made to be less than 180 degree, and make described first friction lines extend to the two ends of described roll shaft main body along the central axis direction of described roll shaft main body, therefore, friction lines is vertical with the direction of advance of described card, and, arranging described first friction lines makes the surface of described roll shaft main body be irregular, therefore, when described roll shaft body rotation, described roll shaft main body can be vibrated card and produce larger frictional force, the phenomenon of skidding is avoided to occur, and then can stablize and rapidly card is sent in card puncher, and described roll shaft main body at every turn can effectively and exactly transfer card, thus, greatly improve printing effect and print quality.
Preferably, the opposite side rubbing the relative described roll shaft main body of lines with described first is provided with the second friction lines, and the angle of the circular arc of the cambered surface at described second friction lines place is less than 180 degree.By arranging described second friction lines, the irregularly shaped of described roll shaft main body can be strengthened further, thus vibration when increasing described roll shaft body rotation, improve the frictional force with card, ensure can stablize each time exactly card to be sent in card puncher.
Particularly, described second friction lines from the middle part of described roll shaft main body centrally direction of principal axis extend to wherein one end of described roll shaft main body.This side half of described roll shaft main body can be made like this to have friction lines, second half lines that do not rub, strengthen the irregularly shaped of described roll shaft main body further, improve the frictional force with card.
Particularly, the angle of the circular arc of the cambered surface at described second friction lines place equals the angle of the circular arc of the cambered surface at described first friction lines place.
Particularly, described first friction lines and described second friction lines are the gear teeth.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model card puncher roll shaft structure.
Fig. 2 is the side diagram of the utility model card puncher roll shaft structure.
Detailed description of the invention
For describing technology contents of the present utility model, structural feature, the effect that realizes in detail, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
As Fig. 1, shown in Fig. 2, the utility model card puncher roll shaft structure 100 comprises central shaft 1 and roll shaft main body 2, described roll shaft main body 2 is fixed on described central shaft 1 coaxially, described central shaft 1 is articulated on described card puncher import bottom surface, the side of described roll shaft main body 2 is higher than the bottom surface of described printer import, the cambered surface of the sidewall of described roll shaft main body 2 is provided with the first friction lines 21, the angle [alpha] of the circular arc of the cambered surface at described first friction lines 21 place is less than 180 degree, and described first friction lines 21 extends to the two ends of described roll shaft main body 2 along the central axis direction of described roll shaft main body 2.The opposite side that rub the relative described roll shaft main body 2 of lines 21 with described first is provided with the second friction lines 22, the angle beta of the circular arc of the cambered surface at described second friction lines 22 place is less than 180 degree, and equals the angle of the circular arc of the cambered surface at described first friction lines 21 place.By arranging described second friction lines 22, the irregularly shaped of described roll shaft main body 2 can be strengthened further, thus the vibration increased when described roll shaft main body 2 is rotated, improve the frictional force with card, ensure can stablize each time exactly card to be sent in card puncher.Described second friction lines 22 from the middle part of described roll shaft main body 2 centrally direction of principal axis extend to wherein one end of described roll shaft main body 2.This side half of described roll shaft main body 2 can be made like this to have friction lines, second half lines that do not rub, strengthen the irregularly shaped of described roll shaft main body 2 further, improve the frictional force with card.In addition, described first friction line 21 tunnel and described second friction line 22 tunnel are the gear teeth.
Compared with prior art, because the utility model by being provided with the first friction lines 21 and the second friction lines 22 in the cambered surface of the sidewall of described roll shaft main body 2, the angle of the circular arc of the cambered surface at described first friction lines 21 and the second friction lines 22 place is made to be less than 180 degree, and make described first friction lines 21 extend to the two ends of described roll shaft main body 2 along the central axis direction of described roll shaft main body 2, and described second friction lines 22 extends to wherein one end of described roll shaft main body 2 along the central axis direction of described roll shaft main body 2 from middle part, therefore, friction lines is vertical with the direction of advance of described card, and, due to the existence of the first friction lines 21 and the second friction lines 22, the surface making described roll shaft main body 2 is irregular, therefore, when described roll shaft main body 2 is rotated, described roll shaft main body 2 can be vibrated card and produce larger frictional force, the phenomenon of skidding is avoided to occur, and then can stablize and rapidly card is sent in card puncher, because described roll shaft main body 2 at every turn can effectively and exactly transfer card, thus, greatly improve printing effect and print quality.
Above disclosedly be only preferred embodiments of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
