Abstract
The utility model relates to a printing rubber roller which is mainly composed of a metal shaft core, a tubular rubber layer and a rigid auxiliary positioning circular table, wherein the tubular rubber layer is fixedly sheathed on the shaft surface of the metal shaft core; the rigid auxiliary positioning circular table is arranged on the metal shaft core, and the radius of the rigid auxiliary positioning circular table is a little smaller than that of the rubber layer. The working skin layer of the rubber roller is accurately positioned in an optimum working position through the direct contact of the rigid auxiliary positioning circular table and a printing plate, so the operation of positioning regulation of the rubber roller is simplified, and simultaneously, printing quality is also ensured. The service life of the printing plate and the rubber roller can also be extended, and the utility model can be used as various rubber rollers for transferring and distributing ink.
Description
The utility model relates to printing rubber roll.
Existing printing rubber roll mainly is made of metal shaft core and the tubulose glue-line that is solidly set on the metal shaft mandrel face.To print China ink in the rolling on the printing forme by the tubulose glue-line surface of rubber roll is delivered to and makes the printing forme inking on the printing forme then be imprinted on the paper.Contact condition between rubber roll top layer and printing forme is how, and is very big to the influence in service life of printing quality, printing forme and rubber roll--as it is too tight to recline, and then roll surface is excessive to the pressure of printing forme, has both influenced printing effect, aggravates the damage of printing forme and rubber roll again; As the pine that reclined, then contact force is light, and even China ink and ink transfer effect will be affected again, also can cause printing effect bad.Contact condition between existing rubber roll top layer and printing forme often judges that by experience the common practice is to place a piece of paper between printing forme and rubber roll, with pulling moving this paper, judges with this paper clamping degree betwixt whether the degree of reclining between rubber roll and printing forme is suitable.This mode of operation of judging by experience fully, accuracy and reliability are not high, and simultaneously its debugging work load is big and should not grasp, and is difficult to guarantee that from value being optimum Working between rubber roll top layer and the printing forme reclines.
The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and provide a kind of printing rubber roll that can make conveniently to be positioned at the printing rubber roll that is good contact condition with printing forme.
The purpose of this utility model is to realize by the coaxial rigidity assist location garden platform that is provided with on the metal shaft core of existing rubber roll.Explosion cavity radius when the radius of this rigidity assist location garden platform and the tubulose glue-line extexine of rubber roll are optimum state and abut on the printing forme equates.Both can according to the elastic characteristic of the skin-material of printing rubber roll at present commonly used with its with printing forme between when being best shape and contact the compression degree on its top layer determine that this rigidity locatees the radius value of garden platform, when its outer garden side face at location garden platform is touched mutually with printing forme the elasticity top layer of rubber roll just be in the best compression ink-condition, make things convenient for rubber roll to be positioned at the purpose of proper operation position thereby reach.
The utility model is the coaxial smaller rigidity assist location garden platform of its radius ratio rubber roll top layer radius that is provided with on the metal shaft core of original printing rubber roll only, make the very convenient optimum condition position that is positioned at exactly of rubber roll, simplify the location adjustment operation of rubber roll greatly, and improved the reliability of location; Simultaneously, axle helps garden, location platform that the rubber roll top layer is remained at printing forme to be the best situation that reclines, printing effect is guaranteed, the life-span of rubber roll and printing forme is prolonged.Can be used as various ink transfers, printing ink glue roller.
Below in conjunction with embodiment and accompanying drawing the utility model is described further.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the left view of Fig. 1
As shown in Figure 1, the utility model is made of metal shaft core 1, the tubulose glue-line 2 and the coaxial assist location garden platform 3 that is arranged on the metal shaft core that are installed on the metal shaft mandrel face.Set-up mode, manufacture technology between metal shaft core and the tubulose glue-line all can be continued to use existing printing rubber roll, assist location garden platform 3 can be directly and the metal shaft core together with manufacturing, also can on existing rubber roll, establish in addition separately.Its set-up mode can be that garden, location platform is made after the garden ring-type interlocking on the metal shaft core, also can adopt alternate manner such as be threaded.It is provided with the position and abuts in the glue-line end face with symmetry and be advisable.According to the compression zone under optimum condition of present rubber roll skin-material, its rubber roll top layer radius and assist location garden platform semidiameter are advisable with 15～25.
Claims (3)
1, a kind of printing rubber roll of convenient location comprises that a metal shaft core and is solidly set on the tubulose glue-line on the core face, it is characterized in that the also coaxial rubber roll assist location garden platform that is provided with its radius less than tubulose glue-line radius on described axle core.
2, printing rubber roll as claimed in claim 1 is characterized in that the radius ratio tubulose glue-line radius of described rubber roll assist location garden platform is little 15～25.
3, printing rubber roll as claimed in claim 1 is characterized in that described assist location garden platform is symmetricly set on the tubulose glue-line endface position of metal shaft core.
