Description
Technical field
The present invention relates to printing machine equipment technical field, be specifically related to a kind of cylinder of rotary printing machine clutch pressure with Novel eccentric covering device.
Background technology
Clutch pressure mechanism in rotary press and squeegee pressure adjusting device generally adopt eccentric stiffener, and eccentric bushing is the vitals of eccentric stiffener.The major function of eccentric bushing is used to supporting printing cylinder, realizes clutch pressure, regulates squeegee pressure, and in order to ensure print quality, pressure adjusting must be sensitive and accurate, and the size of eccentric bushing and morpheme require to have degree of precision.The general principle of eccentric sleeve mechanism is the endoporus spindle nose of printing cylinder being placed in eccentric bushing, the cylindrical of eccentric bushing and endoporus decentraction, be arranged in frame plate hole, change the circumferential position of eccentric bushing in frame plate hole, the center of cylinder just can be made to change, thus reach the object of change two printing cylinder centre-to-centre spacing.
Printing machine is in running and printing process, act on eccentric bushing and wallboard hole by bearing after printing cylinder is stressed, the impulsive force of clutch pressure, adds and constantly produces relative sliding and friction between eccentric bushing and wallboard hole, make the wearing and tearing of wallboard hole and eccentric bushing inevitable.After there are wearing and tearing in eccentric bushing and wallboard hole, the fit clearance in eccentric bushing and wallboard hole is excessive, especially the fit clearance of plate cylinder is large, cylinder is caused to produce vibration in operation process, cylinder rotational angular velocity is uneven, plate cylinder and blanket cylinder can not contact in identical position at every turn, and the ink continuous quadratic on forme transfers to the different position of blanket cylinder, occur printing ghost image.During printing each cylinder type page and blanket cylinder meets or type page and by version ink rubber roll meet time can vibrate, along with wallboard hole wearing and tearing increasing, printing there will be the problems such as ghost image, thick stick, printing plate resistance force reduction.
In long-term running and printing process, due to the effect of resultant pressure, make wallboard hole and eccentric bushing occur wearing and tearing, the wearing and tearing of wallboard hole present elliptical aperture.Wallboard hole bore hole mainly strengthens by existing restorative procedure, the eccentric bushing adapted with it of then joining, adopt this kind of restorative procedure reliable in quality, but need machine all to disintegrate, dismantle whole part, wallboard is transported back manufacturer's numerical control borer and process, cause rehabilitation expense large, cost is high, and the cycle is long, very large on the impact of printing house; Or only dismantle printing cylinder and associated components in printing house, the on-the-spot wallboard hole to wearing and tearing is carried out grinding and is expanded, corresponding eccentric bushing is joined again according to size, the axiality that this kind repairs means wallboard hole is difficult to ensure, each axis hole line of centres depth of parallelism is inadequate, printing cylinder angle can be caused, chromatography difficulty.
In order to solve above-mentioned deficiency of the prior art, the present invention proposes a kind of new solution.
Summary of the invention
The object of the invention is, directly contact with eccentric bushing for the existing eccentric sleeve device wallboard being applied to cylinder of rotary printing machine clutch pressure, when wearing and tearing appear in wallboard hole and eccentric bushing, wallboard hole wearing and tearing present elliptical aperture need repair time, wallboard hole bore hole can only be taked to strengthen, the recovery scenario of the eccentric bushing adapted with it of then joining, cause rehabilitation expense large, cost is high, the technical problems such as the cycle is long, a kind of cylinder of rotary printing machine clutch pressure with Novel eccentric covering device is provided, guarantee that the method for maintaining after eccentric bushing wearing and tearing is simple, equipment downtime is short, improve maintenance efficiency, reduce maintenance cost.
