Specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Refer to Fig. 3 to Fig. 6, the printing cylinder of printer includes plate cylinder 10, rubber cylinder 20 and impression cylinder 30.Version
Cylinder 10 is arranged on the wallboard 100 of printer by plate cylinder arm support 11, makes the axle center 110 of plate cylinder 10 fixing；Rubber rolls
Cylinder 20 is rockably mounted on the wallboard 100 of printer by rubber cylinder arm support 21；Impression cylinder 30 is imprinted with cylinder
Arm support 31 is rockably mounted on the wallboard 100 of printer；
The Quick clutch mechanism of the variable format printer printing roller of the present invention has two sets and is separately mounted to printer
Both sides wallboard 100,100 ' inner side；Often set Quick clutch mechanism includes main clutch air cylinder 3, auxiliary clutch air cylinder 4, prelocalization
Mechanism and rear detent mechanism.
Main clutch air cylinder 3 is vertically mounted obliquely within the medial surface of wallboard 100 and is located under impression cylinder arm support 31
Side, the termination of the piston rod of this main clutch air cylinder 3 is connected to the front lower ends of impression cylinder arm support 31, and this junction point is located at impressing
The front side of the oscillation center of cylinder arm support 31.
Auxiliary clutch air cylinder 4 erects after being straightly fixed on the medial surface of wallboard 100 and being located at impression cylinder arm support 31
Below end, the termination of the piston rod of this auxiliary clutch air cylinder 4 is connected to the rear end of impression cylinder arm support 31, and this junction point is located at pressure
The rear side of the oscillation center of print cylinder arm support 31.
Interior detent mechanism includes servomotor 51, screw mandrel 52, slide block 53, prelocalization roller 54 and pre-positioning block 55；Wherein,
Servomotor 51 passes through a corner bracket 50 and is vertically obliquely fixed on the medial surface of wallboard 100 and is located at impression cylinder
The front lower place of arm support 31；
Screw mandrel 52 is connected on the output shaft of servomotor 51 by a base；
Slide block 53 is threaded on screw mandrel 52；
Prelocalization roller 54 is arranged on the rear end of slide block 53；
Pre-positioning block 55 is arranged on the front portion of described rubber cylinder arm support 21, and the leading flank of this pre-positioning block 55 opens up one
Individual width is more than the U-lag 550 of the diameter of prelocalization roller, so that prelocalization roller 54 is embedded in this U-lag 550.
To include 61, one piece of a post-positioning block, 62, one piece of vertical slats 63 of horizontal batten and one fixed afterwards for detent mechanism afterwards
Position roller 64；Wherein,
Post-positioning block 61 is fixed on the upper surface at the rear portion of impression cylinder arm support 31；
Laterally the inner termination of batten 62 is hinged on the medial surface of wallboard 100；
The upper end of vertical slats 63 is hinged with the rear end of rubber cylinder arm support 21, the middle part of this vertical slats 63 and Cross slat
The external end head of plate 62 is hinged, makes horizontal batten 62 and vertical slats 63 constitute drop to the ground T-shaped；
Positioning roller 64 is arranged on the lower end of vertical slats 63 afterwards, in rubber cylinder 20 and impression cylinder 30 combined pressure, should
Positioning roller 64 is contacted with the upper surface of post-positioning block 61 afterwards.
The Quick clutch mechanism of the variable format printer printing roller of the present invention, the shaft core position 110 of plate cylinder 10 is solid
It is scheduled on irremovable on wallboard 100, the shaft core position of the shaft core position of rubber cylinder 20 and impression cylinder 30 is all removable.
When completing " combined pressure " state, drive servomotor 51 to rotate and drive screw mandrel 52 to rotate, make slide block 53 with front
Positioning roller 54 is moved upwards up to predetermined exact position along screw mandrel 52, plays the effect of positioning.Control the work of main clutch air cylinder 3 again
Stopper rod ejects upwards, and the piston rod of auxiliary clutch air cylinder 4 bounces back downwards, makes impression cylinder arm support 31 suitable with its oscillation center 310
Hour hands swing, so that moving on impression cylinder 30, because rubber cylinder 20 is free state, therefore connect all the time with impression cylinder 30
Touch, impression cylinder 30 also promotes its oscillation center 210 clockwise oscillation of rubber cylinder 20 and upper shifting simultaneously.Due to pre-positioning block 55
It is integrally fixed at the front portion of rubber cylinder arm support 21, therefore also upper shifting, when the lower wall of the U-lag 550 of pre-positioning block 55 is fixed with front
After the lower surface contact of position roller 54, that is, reach precalculated position, now rubber cylinder 20 and plate cylinder 10 realize " pressing ".This
When after positioning roller 64 do not contact (see Fig. 4) with the upper surface of post-positioning block 61, the top power mainly by main clutch air cylinder 3 is realized
" pressing ", auxiliary clutch air cylinder 4 plays the stable effect supporting impression cylinder arm support 31.
When completing " tripping " state, the piston rod of main clutch air cylinder 3 shortens downwards, the piston rod of auxiliary clutch air cylinder 4
Protrude upward, make impression cylinder arm support 31 with its oscillation center 310 counter-clockwise swing, drive impression cylinder 30 to move down, make simultaneously
The upper surface of post-positioning block 61 is contacted with rear positioning roller 64, so that vertical slats 63 is put with the pin joint 60 with horizontal batten 61
Dynamic, promote rubber cylinder arm support 21 also with its oscillation center 210 counter-clockwise swing, and then so that rubber cylinder 20 is also moved down, with version
Cylinder 10 departs from, and pre-positioning block 55 is by rubber cylinder arm support 21 with also moving down.Due in " combined pressure " state, prelocalization
The lower wall of U-lag 550 of block 55 is contacted with the lower surface of prelocalization roller 54, but the upper side wall of U-lag 550 is rolled with prelocalization
Wheel 54 upper surface there is certain interval (see Fig. 6), therefore slide block 53 do not need move, until prelocalization roller 54 upper surface with
The upper side wall contact of U-lag 550, now achieves rubber cylinder 20 and plate cylinder 10 mainly by the top power assisting clutch air cylinder 4
" tripping " (see Fig. 5).
When printing specification changes, when that is, the diameter of plate cylinder 10 becomes big, the diameter of rubber cylinder 20 also become big and with
The diameter of plate cylinder 10 is identical, and the diameter of impression cylinder 30 is constant all the time, and now the piston rod of main clutch air cylinder 3 first bounces back,
The piston rod of auxiliary clutch air cylinder 4 protrudes upward, and so that rubber cylinder 20 is departed from plate cylinder 10, drives servomotor 51, makes cunning
Block 53 moves down with prelocalization roller 54, after the plate cylinder 10 finishing changing major diameter and rubber cylinder 20, then carries out " combined pressure ".
" combined pressure " identical with foregoing description with the principle of " tripping " (see Fig. 7 and Fig. 8).
The Quick clutch mechanism of the variable format printer printing roller of the present invention, using main clutch air cylinder, auxiliary clutch
Cylinder, prelocalization mechanism and rear detent mechanism, not only make the response speed of plate cylinder and " combined pressure " and " tripping " of rubber cylinder
Hurry up, clutch pressure degree of accuracy is high to be changed moreover it is possible to adapt to print product specification.
Above example is used for illustrative purposes only, rather than limitation of the present invention, about the technology people of technical field
Member, without departing from the spirit and scope of the present invention, can also make various conversion or modification, therefore all equivalent
Technical scheme also should belong to scope of the invention, should be limited by each claim.
