Technical field
The utility model relates to printing machinery, is specifically related to a kind of roller and power transmission shaft combination unit of sheet-fed intaglio printing press.
Background technology
Roller and the power transmission shaft combination unit of sheet-fed intaglio printing press (being called for short single recessed machine) generally comprise roller, two roller shaft sleeves and two sections of power transmission shafts at present; Roller comprises roller body and roller axle, and roller axle and roller body link together; Two roller shaft sleeves are corresponding one by one with two sections of power transmission shafts, and roller shaft sleeve is made up of second sleeve and first sleeve, and second sleeve is fixedly connected with power transmission shaft, and first sleeve is connected with second sleeve is dismantled and assembled by connector; Roller axle both ends are corresponding one by one with two roller shaft sleeves, and the end of roller axle is in roller shaft sleeve.Above-mentioned two sections of power transmission shafts are arranged in frame by bearing conventionally, the dead in line of two sections of power transmission shafts.After the both ends of roller axle are arranged on respectively in two roller shaft sleeves (first sleeve be connected with second sleeve after, end corresponding roller axle is wrapped), realize being connected between roller and power transmission shaft; While printing, when motor drives power transmission shaft rotation, power transmission shaft drives roller rotation by roller shaft sleeve.When roller need to be changed, after lower first sleeve dismounting, take out original roller; Then new roller is placed into desired location (roller axle both ends are placed in respectively on second sleeve of two roller shaft sleeves), then first sleeve is loaded onto, first sleeve is wrapped end corresponding roller axle with second sleeve.
In existing roller and power transmission shaft combination unit, the shape of cross section of roller axle is circular, it is circular that the cross section inner edge shape of roller shaft sleeve is similarly, and while printing, the frictional force producing while contact between dependence roller shaft sleeve medial surface and roller axle lateral surface is carried out transmission.In order to ensure reliable transmission between roller shaft sleeve and roller axle, must make roller shaft sleeve medial surface and roller axle lateral surface close contact, but, because the diameter of roller axle exists error, the diameter of the roller axle of some roller is less than roller shaft sleeve, make to contact defective tightness between roller shaft sleeve medial surface and roller axle lateral surface, even between roller shaft sleeve medial surface and roller axle lateral surface, there is gap, so that the frictional force deficiency between roller shaft sleeve and roller axle, in roller runs up process, roller axle is understood bob or is circumferentially skidded, printing chromatography is brought to bad impact.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of roller and power transmission shaft combination unit of sheet-fed intaglio printing press, and this roller and power transmission shaft combination unit can effectively prevent that roller axle is beated and skidded in roller operation process.The technical scheme adopting is as follows:
The roller of sheet-fed intaglio printing press and a power transmission shaft combination unit, comprise roller, two roller shaft sleeves and two sections of power transmission shafts; Roller comprises roller body and roller axle, and roller axle and roller body link together; Two roller shaft sleeves are corresponding one by one with two sections of power transmission shafts, and roller shaft sleeve is made up of second sleeve and first sleeve, and second sleeve is fixedly connected with power transmission shaft, and first sleeve is connected with second sleeve is dismantled and assembled by connector; Roller axle both ends are corresponding one by one with two roller shaft sleeves, and the end of roller axle, in roller shaft sleeve, is characterized in that: the shape of cross section of described roller axle is regular polygon, and the shape of cross section of roller shaft sleeve cavity and size and roller axle match; The sidewall of roller shaft sleeve is provided with at least one and the screw that the cavity of roller shaft sleeve is communicated with, and in described screw, lock-screw is installed, lock-screw and roller axle close contact.
Because the shape of cross section of roller axle is regular polygon, and the inwall of roller shaft sleeve cavity and roller axle match, and therefore can drive roller axle synchronous rotary when the rotation of roller shaft sleeve, effectively prevents that roller axle skids in roller operation process; And, to tighten after lock-screw, lock-screw and roller axle close contact, can further strengthen being connected between roller shaft sleeve and roller axle, prevents in roller operation process roller axle bob or move left and right in roller shaft sleeve.In brief, in the utility model, roller axle is reliably connected with roller shaft sleeve, can effectively prevent that roller axle is beated and skidded in roller operation process, makes roller running more steady.
In concrete scheme, the shape of cross section of above-mentioned roller axle can be regular hexagon, octagon or square.
Above-mentioned screw can be located on second sleeve, also can be located on first sleeve.
In preferred version, the sidewall of above-mentioned roller shaft sleeve is provided with multiple described screws, screw is upwards uniform in the week of roller shaft sleeve, like this, by the close contact of multiple lock-screws and roller axle, make between roller shaft sleeve and roller axle be connected more fastening, and where necessary can be by adjusting the screw-in depth of each lock-screw, the axial location of adjusting roller axle, overlaps the axis of roller axle and the axis of power transmission shaft completely.More preferably in scheme, described screw is consistent and corresponding one by one with the plane quantity that forms roller shaft sleeve medial surface, and center line of bolt hole is perpendicular with corresponding plane.
Connector between above-mentioned first sleeve and second sleeve can adopt bolt.
In the utility model, the shape of cross section of roller axle is regular polygon, and inwall and the roller axle of roller shaft sleeve cavity match, when therefore roller shaft sleeve rotates, can drive roller axle synchronous rotary, effectively prevent that roller axle skids in roller operation process; Can further strengthen being connected between roller shaft sleeve and roller axle by lock-screw, prevent in roller operation process roller axle bob or move left and right in roller shaft sleeve.In brief, in the utility model, roller axle is reliably connected with roller shaft sleeve, can effectively prevent that roller axle is beated and skidded in roller operation process, makes roller running more steady.
