Description
Technical field
The utility model belongs to printing machinery technical field, and the version particularly relating to printing machine is rolled off locking device.
Background technology
Printing machine is in printing process, and version is rolled and clutch action can be occurred.Rolling for flexible print plate, is anilox roll because flexible print plate rolls rear, and anilox roll contacts with the black chamber of sealing again, and therefore, flexible print plate rolls and there will not be oil leakage phenomenon when clutch.But sealing black chamber and version for other rolls for the equipment that directly contacts, independent clutch version is rolled and can be produced the black chamber of sealing and plate cylinder departs from and causes leakage of oil.
Therefore, for this kind of version roll be necessary to develop a kind of can not the arrangement of clutch of leakage of oil ink, to overcome the deficiency that prior art exists.
Utility model content
Technical problem to be solved in the utility model is to provide and a kind ofly the version of leakage of oil ink can not be rolled off locking device, to overcome the deficiency that prior art exists.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of version is rolled off locking device, comprise plate cylinder and roll with version the sealing ink cavity and scraper that contact, be located at the wallboard outside plate cylinder two ends, described plate cylinder two ends have drum shaft, described sealing ink cavity and scraper are fixed on the supporting plate, it is characterized in that: described wallboard offers axle sleeve hole, be provided with eccentric bushing in described axle sleeve hole, described eccentric bushing has eccentric pivot hole, and described drum shaft passes and to be located in described eccentric pivot hole and by the bearings be located in eccentric pivot hole; Described gripper shoe kink is at the inner flange of described eccentric bushing; Described eccentric bushing is connected with driving mechanism.
Be provided with steel bushing in described axle sleeve hole, described eccentric bushing is arranged in steel bushing described in this again.
Described wallboard both sides are fixed with the back-up ring pushing down described eccentric bushing both sides of the edge.
Described eccentric bushing offers the lubricating cup being communicated to described bearing.
Be provided with spacer ring in described eccentric pivot hole, described bearing is fixed on described spacer ring both sides.
Described eccentric bushing two ends are provided with the sealing ring in gap between shutoff eccentric pivot hole and drum shaft and the flange of fixing described sealing ring.
The outer ledge of described eccentric bushing extends engaging lug, and described driving mechanism is connected on described engaging lug.
Adopt said structure, this version is rolled off locking device and version can be made to roll when clutch action, and sealing ink cavity and scraper are followed version in the lump and rolled motion, and sealing ink cavity and version are rolled and fitted all the time, can not be separated, so can not produce the problem of leaking ink.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is A place enlarged diagram in Fig. 1.
Detailed description of the invention
As shown in Figure 1 to Figure 3, version of the present utility model is rolled off locking device, and comprise wallboard 10, plate cylinder 100, the ink cavity contacted with plate cylinder 100 and scraper 20, plate cylinder 100 two ends have drum shaft 101.
Wallboard 10 has axle sleeve hole 11, arranges in this axle sleeve hole 11 in steel bushing 301, steel bushing 301 and be provided with eccentric bushing 400.Wallboard 100 both sides are fixed with the back-up ring 304 pushing down eccentric bushing 400 both sides of the edge, and this back-up ring 304 can stop eccentric bushing 400 to move axially in axle sleeve hole 11.This eccentric bushing 400 has eccentric pivot hole 401, is provided with spacer ring 402 in eccentric pivot hole 401.Drum shaft 101 is located in this spacer ring 402, is supported between spacer ring 402 and drum shaft 101 by bearing 403.And eccentric bushing 400 also offers the lubricating cup 404 being communicated to bearing 403.Be provided with the sealing ring 302 in gap between shutoff eccentric pivot hole 401 and drum shaft 101 and the flange 303 of fixed seal ring 302 at eccentric bushing 400 two ends, flange 303 is fixed on the end face of eccentric bushing 400.
In addition, gripper shoe 500 is located at the inner side of wallboard 10, and kink is at the inner flange of described eccentric bushing, and sealing ink cavity and scraper 20 are fixed on again in gripper shoe 500.
The outer ledge of eccentric bushing 400 extends an engaging lug 405, and this engaging lug 405 connects driving mechanism 600.Driving mechanism 600 can be motor or air cylinder driven mechanism or man-operated mechanism.
Be exactly more than that version of the present utility model is rolled off locking device, its working method is:
When needs plate cylinder 100 is separated with impression cylinder, eccentric bushing 400 is driven to rotate by driving mechanism 600, because drum shaft 101 is arranged in eccentric bushing 400 prejudicially, like this in the process of eccentric bushing 400 rotation, drum shaft 101 just drives plate cylinder 100 to be separated with impression cylinder.When needs plate cylinder 100 and impression cylinder in conjunction with time, driving mechanism 600 only needs reverse drive eccentric bushing 400 to rotate plate cylinder 100 just can be driven to be combined with impression cylinder.No matter be separated and combine, because gripper shoe 500 and eccentric bushing 400 link together, therefore, sealing ink cavity can followed by together with plate cylinder 100 with scraper 20 moves, in motion process, sealing ink cavity fits together with plate cylinder 100 all the time, and the problem of ink leak can not occur.
Therefore, by foregoing detailed description, can find out, the utility model has plate cylinder to be done clutch action and seal oil chamber can not occur and scraper departs from plate cylinder and causes the advantage of ink leak.
The above; it is only preferred embodiment of the present utility model; not any pro forma restriction is done to the utility model; have in any art and usually know the knowledgeable; if in the protection domain not departing from the claim that the utility model proposes; the Equivalent embodiments that local done by the technology contents utilizing the utility model to disclose is changed or modified, and do not depart from technical characteristic content of the present utility model, all still belong in the scope of the utility model technical characteristic.
