Description

A kind of ink roller jumping mechanism

Technical field:

The present invention relates to a kind of ink roller jumping mechanism, be specially adapted to use on the offset print inking system.

Background technology:

The function of the inking system of offset print is to beat fast the China ink that outputs to even ink system from ink fountain even, be transported to uniformly and stably on the forme, wherein the motion of the channeling ink roller in the ink system is most important, and the quality of channeling ink roller motion has directly determined inking system service behaviour and the printing quality of offset print.

Prior art is referring to shown in Figure 1, prior art is made of channeling ink roller and play power, power by gear 13 by main fulcrum 15 fixed delivery, 14 rotations of gear driven crank end cap, crank pin 19 is by nut 16, pad 17 and self-aligning bearing 18 are fixed on the crank end cap 14, the crank pin center does not overlap with crank end cap 14 pivots, depart from certain distance and consist of crank, crank is to be connected with crank pin 19 by connecting rod 12 1 ends, be connected with swinging block 11 on its other end fixing by bearing pin 10, the bearing pin 8 and the play fork 7 that are used for fixing in addition on the play bearing 9 consist of crank-rocker mechanism, play fork 7 is made reciprocally swinging, make to come and go rectilinear motion by needle roller roller 20 and main door 6 with the channeling ink roller of movement machine opposite side, the opposite side of machine, channeling ink roller 1 is fixed on the wallboard by block bearing 2, one end of 9-21 bearing pin puts play fork 4, locate by thrust washer, fork can be swung thereon, the other end then is contained in fulcrum 3 and cuts in the hole at flat place, and be fixed on the fulcrum with nut and packing ring, cover 5 by ink roller by side block, fulcrum 3 and play fork 4 are delivered to remaining ink roller with the reciprocating motion of ink roller radially does reciprocating linear motion it simultaneously, can find out by above structure, traditional printing machine inking roller play has following shortcoming: 1 number of spare parts is many, and structure is disperseed; 2, all roll shifting reaches the limit of the position simultaneously at work, and the simultaneously conversion direction of motion makes rubber roll strengthen the frictional force of printing cylinder, even is linear superposition, has produced black thick stick or ghost image, is unfavorable for very much the offset press working stability; 3, motion is transmitted by needle roller roller 20 and main door 6, side block lid 5, is the line contact, poor rigidity, and very easily producing high temperature when high speed operation, to cause roller to grind bad, and then lead to a disaster; 4, can only control a channeling ink roller in the nonclient area commutation of printing plate device, be unfavorable for the stability of forme China ink.

Summary of the invention:

Task of the present invention is to propose a kind ofly can to adapt to as required different channeling ink roller positions and the requirement of channeling ink amount, has improved a kind of ink roller jumping mechanism of the stability of inking.

Task of the present invention is finished like this, a kind of ink roller jumping mechanism, it comprises the channeling ink roller, gear transmission, it is characterized in that: the opposite, left side of inclined shaft is equipped with angular contact ball bearing, be installed in the splicing sleeve of frame plate and lock by locking member, gear is housed on the inclined shaft to be connected by key, the right-hand member of inclined shaft is packed into by bearing in the hole of support plate, be fixed on the fulcrum on the frame plate by screw in compression around the support plate, the middle part of inclined shaft is by the bearing oscillating deck of packing into, in the hole around the oscillating deck door being housed is connected with the channeling ink roller, be connected with band handle oscillating bearing on the oscillating deck, described band handle oscillating bearing is divided into, lower two, part is fixed by little fulcrum and frame plate on it, and its lower part is connected with oscillating deck.The two-piece centre of described band handle oscillating bearing is connected with connecting rod, and the external thread rotary on the connecting rod two ends is to being connected with band handle oscillating bearing internal thread on the contrary and being locked by locking nut.

The present invention has following effect: compact conformation, succinct, number of spare parts is few.Main part only has oscillating deck, gag lever post and transmission inclined shaft, when roll shifting moves back and forth, the direction of rotation of inclined shaft and play roller in the determining positions of hole periphery the play roller reach the limit of the time sequencing of position, several roll shiftings can not arrive the extreme position of play simultaneously, reach the limit of simultaneously the position with traditional mechanism and compare, roll shifting is to the simultaneously stressed in the same way disadvantageous situation of printing unit when greatly having improved the jumping mechanism commutation.In addition, the supporting reaction force that the main actuator inclined shaft of roll shifting campaign produces is all born by frame, and is born by the printing unit of machine unlike traditional structure.Improved the operating mode of printing unit.Two roll shiftings of close printing cylinder can successively in the inoperative zone commutation of plate cylinder, have been avoided the adverse effect of roll shifting commutation force direction change to printing in the plate cylinder working region.
