Description
Technical field
The utility model relates to a kind of rubber roller, and more particularly, it relates to a kind of fixed rubber roller.
Background technology
Blanket roller, in indirect printing by the printing ink transfer of forme picture and text to the transfer printing roller on stock, its surface parcel blanket.Rubber roller makes the picture and text ink marks on forme transfer on paper, completes the indispensable parts of printing work.As shown in Figure 6 and Figure 7, rubber roller comprises roller and end wall, and the clamping device 3 of blanket is housed in roller, and end wall is provided with strainer.Blanket can clamp by clamping device, strainer comprises worm gear 1 and worm screw 5, and worm gear is connected with clamping device key, the angle regulating worm gear wheel is rotated by worm screw, reach the angle regulating clamping device to rotate, and then reach and regulate the effect of blanket tensile force: worm gear drives clamping device inwardly to rotate, the blanket tensile force that is stretched improves, and worm gear drives clamping device outwards to rotate, then tensile force reduces.
But, during reality is produced, because worm screw is not fixed, free force is there is between worm and wheel, rubber roller is the tension force that constantly changed of blanket in use, causes worm gear easily to rotate, and worm screw is vulnerable to external force twisting and rotates simultaneously, worm screw is reduced the position-limiting action of worm gear, causes worm gear wheel that the tensile force of blanket is changed.
Therefore, need strainer to be fixed, prevent the rotation of worm gear in production process, keep the tensile force of blanket to remain unchanged.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of fixed rubber roller, worm gear can be effectively prevented to be subject to the twisting of clamping device, after ensureing clamping device adjustment, worm gear no longer rotates by its effect, the tensile force of blanket is remained unchanged, blanket surface corrugationless in printing process, improves printing quality.
For achieving the above object, the utility model provides following technical scheme: a kind of fixed rubber roller, comprise end wall, worm bracket and worm gear, worm bracket is fixed on end wall surface, described worm wheel surface is provided with position-limit mechanism, described position-limit mechanism comprises locating part, and described worm gear is fixed by locating part and worm bracket or end wall.
By adopting technique scheme, locating part is by worm gear and worm bracket or end wall is fixed, worm gear can be effectively prevented to be subject to the twisting of clamping device, after ensureing clamping device adjustment, worm gear no longer rotates by its effect, the tensile force of blanket is remained unchanged, blanket surface corrugationless in printing process, improves printing quality.
The utility model is set to further: described position-limit mechanism comprises locating hole, described locating hole is positioned at the side of worm gear, described locating part is bolt, one of screw or alignment pin, and locating part is arranged in locating hole, and described worm gear is fixed by locating part and worm bracket or end wall.
By adopting technique scheme, worm bracket and end wall fix, and therefore worm bracket and end wall all carry out spacing by locating part to worm gear, prevent it from rotating.Bolt, screw or alignment pin are handware common in daily machinery production, and all can carry out spacing to locating hole, stop worm gear wheel, keep the tensile force of blanket constant.
The utility model is set to further: described worm gear is fixed by locating part and worm bracket, and worm bracket is integrally formed with extension, and extension is provided with the through hole worn for locating part.
By adopting technique scheme, the setting of extension, for increasing the length of worm bracket, facilitates wearing of the setting of through hole and locating part; Extension and worm bracket are wholely set, and effectively can improve the structural strength of extension, prevent the fracture of extension in the spacing process of worm gear.
The utility model is set to further: described locating part is bolt, and described through-hole wall is provided with the screw thread engaged with bolt.
By adopting technique scheme, the threaded engagement of bolt and through-hole wall, makes bolt tighten by screw thread in spacing, prevents it from coming off.

Detailed description of the invention
Referring to figs. 1 through Fig. 5, the fixed rubber roller embodiment of the utility model is described further.
A kind of fixed rubber roller, comprise end wall 6, worm bracket 2 and worm gear 1, worm bracket 2 is fixed on end wall 6 surface, described worm gear 1 side is provided with locating hole 11, worm bracket 2 is connected with extension 21, and extension 21 and worm bracket 2 integral type are arranged, and extension 21 is provided with screwed hole 22, be equipped with bolt 23 in screwed hole 22, bolt 23 engages with screwed hole 22 and bolt 23 is arranged in locating hole 11.
The setting of extension 21, for increasing the length of worm bracket 2, facilitates wearing of the setting of screwed hole 22 and bolt 23; Extension 21 and worm bracket 2 are wholely set, and effectively can improve the structural strength of extension 21, prevent the fracture of extension 21 in the spacing process of worm gear 1.
Bolt 23 is successively through screwed hole 22 and locating hole 11, worm gear 1 is clamped by bolt 23 and worm bracket 2 phase, clamped by bolt 23 and clamp without the need to worm screw 5 and worm gear 1 phase, the power of worm gear 1 pair of worm screw 5 is reduced, carry out spacing by means of only bolt 23, stop the rotation of worm gear 1, worm gear 1 can be effectively prevented to be subject to the twisting of clamping device 3, after ensureing clamping device 3 adjustment, worm gear 1 no longer rotates by its effect, the tensile force of blanket 4 is remained unchanged, the surperficial corrugationless of blanket 4 in printing process, improves printing quality.
Meanwhile, bolt 23 is meshed with the inner thread of screwed hole 22, and bolt 23 is tightened by screw thread in spacing, prevents bolt 23 from coming off, and strengthens fixed effect.
Wherein, worm gear 1 side has 12 screwed holes 22, spacing identical (namely screwed hole 22 is evenly distributed) between adjacent screwed hole 22, and the axis angle of adjacent screw holes 22 is 30 °, and when regulating clamping device 3, the angle of rotation is more easy to control, without the need to measuring.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
