The axle center of plate cylinder 10 is fixed；Rubber cylinder 20 is rockably mounted to the two sides of printing machine by rubber cylinder cantilever crane 20a
On wallboard 100；Impression cylinder 30 is rockably mounted on the two sides wallboard 100 of printing machine by impression cylinder cantilever crane 30a.
The rubber cylinder of printing machine and the clutch pressure mechanism of plate cylinder have two sets and are separately mounted to the two sides of printing machine
On wallboard 100；Every set clutch pressure mechanism includes impression cylinder clutch oil cylinder 3, rubber cylinder clutch.
Impression cylinder clutch oil cylinder 3 is vertically mounted obliquely on the medial surface of wallboard 100 and is located at impression cylinder cantilever crane
The lower section of 30a, the end of the piston rod of the impression cylinder clutch oil cylinder 3 are connected to the middle part lower end of impression cylinder cantilever crane 30a.
Rubber cylinder clutch includes rubber cylinder clutch oil cylinder 40, drive block 41, clutch support 42, positioning pile crown
43, locating piece 44 and position-limit mechanism；Wherein:
Rubber cylinder clutch oil cylinder 40 installs the front lower place on the medial surface of wallboard 100 and being located at impression cylinder cantilever crane 30a；
Drive block 41 is connected on the piston rod of rubber cylinder clutch oil cylinder 40；
Clutch support 42, which is mounted on the lateral surface of drive block 41 and passes through the slot opened up on wallboard 100, is located at wallboard
A linking arm 420 is installed on the upper inner face of the clutch support 42 in 100 outside；
Positioning pile crown 43 is installed in rotation on the rear end of linking arm 420；
Locating piece 44 is mounted on the front upper part of rubber cylinder cantilever crane 20a, and one is opened up in the anterior face of the locating piece 44
Width is greater than the locating slot 440 of the lateral kidney-shaped of the diameter of positioning pile crown 43, makes to position pile crown 43 rollably embedded in the positioning
In slot 440；
Position-limit mechanism includes limit electric machine 45, screw rod 46, limited block 47 and limited post 48；Limit electric machine 45 is servo electricity
Machine, the limit electric machine 45 install the front lower place on the lateral surface of wallboard 100 and being located at impression cylinder cantilever crane 30a；Screw rod 46 connects
In the shaft of limit electric machine 45；Limited block 47 is threaded on screw rod 46 and is located at the guide groove opened up on clutch support 42
It is interior, the limiting slot 470 of a vertical kidney-shaped is opened up on the limited block 47；Limited post 48 is located in the limiting slot 470 of limited block 47
And it is fixed on the lateral surface of drive block 41.
The rubber cylinder of the printing machine of the utility model and the clutch pressure mechanism of plate cylinder, the axle center position of plate cylinder 10
Setting makes to be fixed on irremovable on wallboard 100, and the shaft core position of rubber cylinder 20 and the shaft core position of impression cylinder 30 are removable
It is dynamic.
When completing rubber cylinder 20 and plate cylinder 10 " combined pressure " state, start the piston of rubber cylinder clutch oil cylinder 40
Bar stretching is moved upwards with drive block 41, and drive block 41 is moved up with clutch support 42, makes to be mounted on linking arm 420
The positioning pile crown 43 of rear end is contacted with the upper side wall of the locating slot 440 on locating piece 44, is put upwards with rubber cylinder cantilever crane 20a
It is dynamic, make rubber cylinder 20 close to plate cylinder 10, rubber cylinder 20 can't be bonded completely with plate cylinder 10 at this time, it is also necessary to
Certain gap, this gap are to be guaranteed by position-limit mechanism, therefore when completing " combined pressure ", should first start limit electric machine 45
Rotation stops after making screw rod 46 that limited block 47 be driven to be moved upwards up to scheduled exact position along the guide groove on clutch support 42
Only, the piston rod for restarting rubber cylinder clutch oil cylinder 40 stretches out.Since the limited post 48 being fixed on drive block 41 is to be embedded in
In the limiting slot 470 of limited block 47, therefore it cannot be moved up again when limited post 48 moves to the top of limiting slot 470,
It ensure that the gap between rubber cylinder 20 and plate cylinder 10, this gap needs to disappear by the promotion of impression cylinder 30
It removes.Since the width of the locating slot 440 on the locating piece 44 that is fixed on rubber cylinder cantilever crane 20a is slightly larger than positioning pile crown 43
Diameter, therefore rubber cylinder cantilever crane 20a is still free state, and the piston rod of impression cylinder clutch oil cylinder 3 is driven to stretch out at this time,
Drive impression cylinder cantilever crane 30a to be swung up, by impression cylinder cantilever crane 30a it is upward to push dynamic rubber cylinder cantilever crane 20a upward
It is mobile, until the lower wall of the locating slot 440 on locating piece 44 is contacted with positioning pile crown 43, that is, reaches rubber cylinder 20 and printed
The position that plate cylinder 10 is bonded completely, rubber cylinder 20 and plate cylinder 10 realize " pressing " (see Fig. 1 and Fig. 2) at this time.Due to
The gap of locating slot 440 and positioning pile crown on locating piece 44 is fixed, so can steadily roll rubber cylinder and printing plate
Cylinder closes.
When completing " tripping " state, the piston rod of pioneer's dynamic pressure print cylinder clutch oil cylinder 3 is retracted downwards, makes impression cylinder
Cantilever crane 30a drives impression cylinder 30 to move down to lower swing, and releases the upward thrust to rubber cylinder cantilever crane 20a, due to
In " combined pressure " state, the lower wall of the locating slot 440 on locating piece 44 is contacted with positioning pile crown 43, but locating slot 440 is upper
There are certain intervals for side wall and positioning pile crown 43, therefore release the rubber cylinder cantilever crane 20a of thrust to lower swing, until positioning
The upper side wall of slot 440 is contacted with positioning pile crown 43, is bounced back at this time in the piston rod by rubber cylinder clutch oil cylinder 40 with driving
Block 41 downwards, and is moved downward with the positioning pile crown 43 of the rear end of clutch support 42 and linking arm 420, realizes rubber cylinder
20 with " tripping " (see the Fig. 3 and Fig. 4) of plate cylinder 10.
In order to improve stability of the rubber cylinder 20 when with 30 clutch pressure of plate cylinder, rubber cylinder cantilever crane 20a's
Front lower portion installs cantilever crane sliding slot, and a cantilever crane guide rail 21 being adapted to cantilever crane sliding slot is installed on the medial surface of wallboard 100, makes
Rubber cylinder cantilever crane 20a is swung up and down along cantilever crane guide rail 21.While in order to limit the bottom amount and rubber of impression cylinder cantilever crane 30a
Roller cantilever crane 20a bottom amount installs an impression cylinder stop-motion seat 31 and rubber cylinder stop-motion seat on the medial surface of wallboard 100
22。
In addition one potentiometer connecting with clutch support 42 5 is also installed on the lateral surface of wallboard 100, potentiometer is passed through
The signals of 5 feedbacks, obtain the shift position of clutch support 42, by the revolving speed and turnning circle of process control limit electric machine 45,
Adjust " combined pressure " speed and pressure between rubber cylinder and printing plate rolling.
The rubber cylinder of the printing machine of the utility model and the clutch pressure mechanism of plate cylinder, the clutch pressure of rubber cylinder
Structure uses clutch and position-limit mechanism, and clutch is driven using oil cylinder, is able to achieve fast clutch.Position-limit mechanism uses servo
Motor control keeps clutch pressure accuracy high, clutch is steady convenient for adjusting " combined pressure " pressure between rubber cylinder and printing plate rolling
It is fixed, it is easy to operate, manpower is saved, printing product specification variation is adapted to.
Above embodiments are only for illustration of the utility model, rather than limitations of the present invention, related technical field
Technical staff can also make various transformation or modification in the case where not departing from the spirit and scope of the utility model, because
This all equivalent technical solution also should belong to the scope of the utility model, should be limited by each claim.
