Abstract
The utility model discloses a roller driving mechanism for a printing machine. A fixing seat (3) and a bearing sleeve (5) are fixed on an online side wallboard (6); a driving shaft (1) is arranged in the fixing seat (3) and rotates through an elastic retainer ring; when a roller shaft (7) is inserted into the driving shaft (1), a gap between the driving shaft (1) and the roller shaft (7) is eliminated through a pretightening screw (4) arranged on the outer side of the driving shaft (1). By the roller driving mechanism for the printing machine, the gap between the driving shaft and the roller shaft can be eliminated during use, and the driving precision is improved, so that the printing quality is improved, the wastes are reduced, and lots of time and paper cost are saved; and meanwhile, the processing precision of a roller driving shaft head is reduced, and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of edition roller driving mechanism, particularly a kind of version roller driving mechanism of printing equipment.
Background technology
At present, the printing machine of using on the market adopts driving shaft to drive through the mode that transition connects with the version roll shaft mostly, like this in the process of using; As time goes on; Transition connects and can lose efficacy gradually, thereby can make the drive gap between driving shaft and the version roll shaft become big, influences transmission accuracy; Cause printing quality to descend, wasted great amount of time and paper cost.
Therefore, demand developing a kind of version roller driving mechanism of printing machine urgently,, improve printing quality to improve transmission accuracy.
The utility model content
The purpose of the utility model is; Version roller driving mechanism through a kind of printing machine is provided is connected in the process of use with the transition that overcomes existing driving shaft and version roll shaft; As time goes on, transition connects and can lose efficacy gradually, thereby can make the drive gap between driving shaft and the version roll shaft become big; Influence transmission accuracy, the shortcoming that causes printing quality to descend.
The utility model is to adopt following technical scheme to solve.
A kind of version roller driving mechanism of printing machine, holder 3 is fixed on the online framed side wallboard 6 with bearing holder (housing, cover) 5; Driving shaft 1 is installed on rotation in the holder 3 through circlip; Version roll shaft 7 inserts in the driving shafts 1, be provided with in the outside of driving shaft 1 eliminate driving shaft 1 and version roll shaft 7 gaps hold out against nail 4.
Aforesaid circlip comprises, the hole with back-up ring 2, axle with first back-up ring 10, spool with second back-up ring 13.
The version roller driving mechanism of the utility model printing machine compared with prior art, has following remarkable advantages and beneficial effect:
The version roller driving mechanism of the utility model printing machine can be eliminated the gap between driving shaft and the version roll shaft in the process of using, improve to drive precision, thereby improve printing quality, reduces waste product, has saved great amount of time and paper cost.Reduce the machining accuracy of version roller driving axle head simultaneously, reduced production cost.
Description of drawings
Fig. 1 is the front section view of the utility model.
Wherein, 1 for driving shaft, 2 holes uses back-up ring, 3 for holder, 4 for hold out against nail, 5 for bearing holder (housing, cover), 6 for online framed side wallboard, 7 for an edition roll shaft, 8 be that the 3rd bearing, 10 is that spool to use first back-up ring, 11 be that second bearing, 13 is spool to use second back-up ring as clutch shaft bearing, 12 as bearing gland, 9.
The specific embodiment
Figs and embodiment further specify the utility model:
Fig. 1 is the front section view of the utility model.
See also shown in Figure 1; Holder 3 is fixed on the online framed side wallboard 6 with bearing holder (housing, cover) 5; Driving shaft 1 is installed on holder 3 interior rotations with first back-up ring 10, clutch shaft bearing 11, second bearing 12 and axle with second back-up ring 13 etc. through circlip for hole 2, axle; When version roll shaft 7 inserts driving shaft 1, hold out against to eliminate the gap of 7 on driving shaft 1 and version roll shaft through holding out against nail 4,8 among the figure is the 3rd bearing for bearing gland, 9.Improve the driving precision through above technological means, thereby improved printing quality, reduced waste product, saved great amount of time and paper cost.
What should explain at last is: above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this specification has carried out detailed explanation to the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of the spirit and the scope of utility model, and it all should be encompassed in the middle of the claim scope of the utility model.
Claims (2)
1. the version roller driving mechanism of a printing machine, holder (3) and bearing holder (housing, cover) (5) are fixed on the online framed side wallboard (6); It is characterized in that: driving shaft (1) is installed on rotation in the holder (3) through circlip; Version roll shaft (7) inserts in the driving shaft (1), be provided with in the outside of driving shaft (1) eliminate driving shaft (1) and edition roll shaft (7) gap hold out against nail (4).
