Abstract
The cylinder engaging and disengaging impresison device for press is characterized by that it adopts two cylinders serially-connected together to drive rack rod and engage it with gear on the gear shaft and through the key to drive the gear shaft and make it rotate, then uses the gear shaft to drive blanket cylinder and two end segment gears to drive eccentric sleeve and cylinder, and utilizes the movements of the above-mentioned two cylinders serially-connected togther one after another to implement the engaging and disengaging impression movement of blanket cylinder and plate cylinder and inked blanket cylinder and impression cylinder twice. Said invention possesses advantages of simple structure, twice engaging and disengaging impression and complete inking on pinting paper with little waste of paper.
Description
The present invention relates to a kind of cylinder clutch pressure device of printing machinery, be specially adapted to the cylinder of rotary printing machine clutch and press.
On the present printing machine in the cylinder clutch laminated structure, useful many link type of mechanical type structure, as the printing machine of the good bright company of Japan, owing to adopt multi-connecting-rod mechanism, complex structure, link is many, and low precision is pressed in clutch.There is complex structure too in and for example domestic four opening and majority such as two starts all adopts mechanical type clutch laminated structure of producing in the past, and link is many, problems such as low precision.In addition, on printing machine, begin at present both at home and abroad to adopt single air clutch laminated structure, but this structure can only be finished a clutch and presses work.In printing process, can produce the inkless or black defective such as shallow of former Zhang Yinpin like this, and the paper product waste is bigger.
The object of the present invention is to provide a kind of structure simpler, link is few, the precision height, and print quality is good, and can finish the cylinder clutch pressure device that double-clutch is pressed.
Purpose of the present invention is realized by following technical scheme:
A kind of cylinder clutch pressure device of printing mechanism, being specially adapted to the cylinder of rotary printing machine clutch presses, it is characterized in that the gear 16 that adopts two cylinders that are cascaded 10,11 to go to promote on tooth bar 5 and the tooth axle 12 meshes, driving tooth axle 12 by key 25 rotates, tooth axle 12 drives the sector gear 13 at rubber cylinder 2 two ends and promotes eccentric bushing 19, by the priority action of cylinder 10,11, the double-clutch of finishing rubber cylinder 2 and plate cylinder 1 and rubber cylinder 2 and impression cylinder 4 successively presses work.
The present invention also can further be realized by following technical measures:
According to aforesaid device, cylinder 10,11 1 ends of series connection are fixed on the support 14, and the other end is connected with tooth bar 5, and tooth bar 5 left and right sides are in bond, gear 5 on one side and gear 16 mesh, one side with eccentric shaft 26 on wheel 15 near.
According to aforesaid device, the cylinder 10,11 of series connection, by the piston 10-1 motion of cylinder 10, the back presses work by cylinder body (11-2) motion of cylinder 11 with the double-clutch of finishing cylinder successively earlier.
According to aforesaid device, on rubber cylinder 2, be provided with one by buffer stopper 3, compression spring 17 and bar 20 forms reduce pressing between rubber cylinder 2 and plate cylinder 1 and the impression cylinder 4 time impact and compensate sector gear 13 and the compensation mechanism of the back lash of 12 on tooth axle.
Advantage of the present invention is: because employing is simple in structure, two cylinder tandem pneumatic formula cylinder clutch that link is few are pressed, and have not only reduced connecting link, have also reduced accumulated error simultaneously, make the cylinder pressure at two ends be easy to regulate consistent.Simultaneously,, can finish cylinder double-clutch and press work, thereby avoid printing scarce China ink in process of production and the shallow defective of China ink, also reduce the waste of printed sheet owing to adopt two cylinder series connection.
The present invention is further illustrated below in conjunction with Figure of description and embodiment
Fig. 1 is a structure principle chart of the present invention
Fig. 2 is the A-A cutaway view of Fig. 1
In Fig. 1 embodiment, be cascaded with two cylinders 10,11, their end is fixed on the support 14, and the other end is connected with tooth bar 5.And tooth bar 5 left and right sides (or claiming constraint) in bond, it meshes with gear 16 on one side, and the wheel 15 on another side and the eccentric shaft 26 tightly is close to, with the back lash of minimizing gear 16 with tooth bar 5.It is in order to finish the double-clutch of cylinder respectively that two cylinders are cascaded, and their course of work is such:
At first cylinder 10 motions, the air inlet from the air inlet A of cylinder 10 of control air-flow, promote piston rod 10-1, the tooth bar 5 that is connected on the piston rod (is called for short axle 12 with tooth axle 12, gear 16 engagements down together), drive axle 12 turning cylinders 12 respectively through bearing 17 by key 25,18 are bearing in wallboard 22, on 23, axle 12 drives the sector gear 13 at rubber cylinder 2 two ends, and then promotion is fixed on the eccentric bushing 19 on the rubber cylinder 2, rubber cylinder 2 is rotated, finish the action of the combined pressure of rubber cylinder 2 and plate cylinder 1, intact China ink on the plate cylinder 1, with exhaust hood 11 motions, from air inlet B air inlet,, therefore cylinder body 11-2 is moved because the end of piston rod 11-1 is fixed on the support 14 and can not moves, and then drive cylinder 10 and tooth bar 5 etc. are finished the pressure of clutch for the second time process, i.e. rubber cylinder 2 and the combined pressure process that impresses rolling 4.Can begin formal printing after twice combined pressure, such a piece of paper just can avoid paper more to waste all to China ink.
When the cylinder exhaust, finish the tripping of cylinder on the contrary, operation principle is identical with combined pressure.
