Specific embodiment
Printing machine includes offset printing unit, and it includes roller cylinder that offset printing unit, which includes roller mechanism, and roller cylinder is used for
Printing plate is installed, roller cylinder will be on roller axis, this is the prior art, is repeated no more.
Referring to attached drawing, installation and continuous printing in present embodiment for the ease of printing plate, roller mechanism is in roller cylinder 4
It is equipped with loading slot 41, different from the big notch on conventional batch roller cylinder, loading slot is only that fluting form is inserted for printing plate
Enter, can satisfy the demand of continuous printing, slot as small gap, it is negligible for the spacing between continuous printing unit pattern not
Meter.Duct 42 is additionally provided in roller cylinder 4, the setting lock version bull stick 2 in duct 42, the lock matching rotation of version bull stick 2 adjusts setting and exists
In duct, duct can be circular hole road, and lock version bull stick can match rotation in duct, and lock version bull stick 2 is become by adjusting rotation
Change position.Loading slot 41 is connected to duct 42, and lock version bull stick 2 is equipped with lock version slot 21, and lock version slot 21 is connected with loading slot 31 matches
It closes, the version head and version tail of printing plate 40 are inserted into loading slot 31, and printing plate version tail can also be inserted into lock version slot 21.
Locking mating surface 43 is additionally provided on roller cylinder 4, locking mating surface 43 is engaged between loading slot and duct, and locking is matched
There is locking fit clearance between conjunction face and lock version bull stick 2.By printing plate version head and version tail locking mating surface and lock version bull stick it
Between locking fit clearance internal locking.Locking mating surface 43 can be cambered surface or male and fomale(M&F)；In the present embodiment, locking mating surface is
Plane, it is easy to process.
When offset printing forme is installed, the printing plate version head of bending and molding can be inserted into loading slot, version head insertion section
It point reclines (be located at locking fit clearance in) with locking mating surface, then by printing plate after the circle of roller cylinder one, by bending and molding
Printing plate version tail be also inserted into loading slot until be inserted into lock version slot in, then by adjust rotation lock version bull stick, make lock version
Lock version slot change location on bull stick, lock version bull stick is in the facial version tail and version head clamping by printing plate of locking cooperation；Lock version bull stick
Printing plate can also be tensioned and be attached on roller cylinder during rotation lock.Printing plate is easy for installation, is not susceptible to after locking printing plate
Displacement.
The mode for adjusting rotation lock version bull stick is more, for example using motor driven output gear and locks the input on version bull stick
Gear cooperation.Referring to attached drawing, in present embodiment, it is separately connected rolling pillow 5 in the two sides of roller cylinder 4, the end of lock version bull stick 2 is
Driving end K(such as hexagonal wrench head), driving end is located at the outside of rolling pillow 5；In the present embodiment, rolling pillow 5 is mounted in the two of roller cylinder 4
Side, the both ends of lock version bull stick are driving end, and the rolling pillow that the driving end at both ends is each passed through two sides is exposed at rolling pillow outside, artificial logical
It crosses spanner and pulls driving end and drive and lock version bar rotation.Lock version bull stick 2 is also equipped with bull stick locking device 6, bull stick locking device energy
It is enough to lock lock version bull stick, it prevents from loosening the next lock version bull stick of plate lock-ups；In the present embodiment, bull stick locking device is arranged
On rolling pillow 5.The rolling pillow combined pressure of rolling pillow, transfer platen configuration that roller cylinder configuration rolling pillow can also be configured with inking roller to rolling,
Pressure is more stable.Each rolling pillow carries out rolling setting around central shaft, and the outer ring for rolling pillow is that periphery is mutually leaned on for rolling.It can be with
Rolling pillow is coaxially disposed with roller cylinder.
In the present embodiment, bull stick locking device includes gripping block 11, and the outside of rolling pillow, gripping block is arranged in gripping block 11
11 have holes for clamping 12 and clamping slot 13, and lock version bull stick is arranged in holes for clamping, and clamping slot is connected to holes for clamping, is matched in gripping block
Have the fastener 14(such as screw for adjusting clamping slot gap), when tightening fastener parts make the gap of clamping slot become smaller, holes for clamping also will
Lock version bull stick can be clamped by becoming smaller, and loosening fasteners are then on the contrary.
It is of course also possible to the setting rolling pillow not on roller cylinder, but rolling pillow is arranged on roller axis, rolling pillow is around its center
Axis rolls setting, and rolling pillow is coaxially disposed with roller cylinder.Then lock the driving end of the end of edition bull stick located immediately at the outside of roller cylinder,
Corresponding bull stick locking device is arranged in the outside of roller cylinder, and the outside of roller cylinder is arranged in the gripping block of bull stick locking device, presss from both sides
Tight block has holes for clamping and clamping slot, and lock version bull stick is arranged in holes for clamping, and clamping slot is connected to holes for clamping, is furnished in gripping block
The fastener (such as screw) in clamping slot gap is adjusted, when tightening fastener parts make the gap of clamping slot become smaller, holes for clamping will also become smaller
Lock version bull stick can be clamped, loosening fasteners are then on the contrary.Roller cylinder is arranged on roller axis, setting rolling pillow, rolling on roller axis
Pillow is coaxially disposed with roller cylinder.The corresponding rolling pillow of roller cylinder is arranged on roller axis and the rolling pillow of inking roller configuration, transfer platen
For the rolling pillow combined pressure of configuration to rolling, pressure is more stable.Each rolling pillow carries out rolling setting around central shaft, and the outer ring for rolling pillow is periphery
It is mutually leaned on for rolling.
The axial setting in duct 42, can lock printing plate in roller cylinder axial direction each position, structure arrangement is more reasonable.Installation print
When version, then (it can will be located at locking between the foldable formed printing plate version head insertion locking mating surface of bending and lock version bull stick
In fit clearance), the version tail of printing plate is inserted into the lock version slot of lock version bull stick, is rotated further by the both ends lock that lock version bull stick carries out printing plate
Tightly, printing plate version head and version tail in locking mating surface and are locked into the locking fit clearance internal locking between version bull stick.
