Abstract
The invention discloses a uniform waver mechanism which relates to a printing machine. The invention aims to provide a uniform waver mechanism which can avoid producing double images or ghost images, and has the technical proposal that the uniform waver mechanism comprises a main string roller, two vice string rollers, four version rollers and a version roller. Rotary wheels on the ends of two swing rods are positioned in the annular groove of the main string roller; the roller wheels on the other ends of two swing rods are respectively positioned in the annular grooves of one vice string roller and a first string roller; the rotary wheel on one end of a third swing rod is positioned in the annular groove of the other vice string roller; the rotary wheel on the other end of the third swing rod is positioned in the annular groove of the first string roller. The invention can be applied to rubber rollers.
Description
Technical field:
The present invention relates to a kind of printing machinery, particularly a kind of ink distribution mechanism that is used for offset press.
Background technology:
The offset press of offset press, especially wide format ghost image occurs, ghost is an a great problem on the printing.The reason that causes ghost image and ghost is that existing ink distribution mechanism is unreasonable, main string roller makes four to lean on ink roller to make axial motion on plate cylinder by three forks and two secondary string rollers, realize the purpose of even China ink, but because that three forks are provided with is reasonable inadequately, four copy rollers are done in the same way, and string moves, thereby plate cylinder is subjected to the effect of the axial motion power of four copy rollers, and its end play can strengthen, and causes producing ghost image and ghost.
Summary of the invention:
The purpose of this invention is to provide a kind of ink distribution mechanism of avoiding producing ghost image and ghost.Technical scheme of the present invention is, a kind of ink distribution mechanism, comprise main string roller, two secondary string rollers, four copy rollers, plate cylinder, the roller of two fork one ends places in the cannelure of main string roller, the roller of its other end places respectively in the cannelure of a secondary string roller and the first string roller, it is characterized in that: an end roller of the 3rd fork places in the cannelure of another secondary string roller, and the roller of the other end places in the cannelure of the first string roller.It is effective and can avoid producing the remarkable advantage of ghost image and ghost that the present invention has even China ink compared with the prior art.
Description of drawings:
Fig. 1 is an existing ink distribution mechanism schematic diagram of the present invention, and Fig. 2 is an ink distribution mechanism schematic diagram of the present invention.
The specific embodiment:
In conjunction with above-mentioned accompanying drawing the present invention is described in detail, existing ink distribution mechanism is that four copy rollers 2 contact with plate cylinder 1 respectively, two secondary string rollers 3,8 contact with two rollers of four copy rollers respectively, roller on three fork 4,7,9 one ends places in the cannelure on the main string roller 5, the roller of fork 4 other ends places in the cannelure on the secondary string roller 3, the roller of fork 7 other ends places on the first string roller in 6 the cannelure, the roller of fork 9 other ends places in the cannelure on another secondary string roller 8, (referring to Fig. 1).This ink distribution mechanism is done identical moving axially by fork with two moving four copy rollers of secondary string roller strap when main string roller is made axial float, thereby plate cylinder is subjected to the effect of the axial force of four copy rollers, through effect repeatedly for a long time, its end play increases, plate cylinder occurs and move axially, thereby ghost image or ghost appear in printing.In order to eliminate this defective, the axial float direction of four copy rollers can be resolved in the same way.For this reason, fork and the contacted end roller of main string roller are placed in the cannelure on the first string roller (referring to Fig. 2), be resolved after the improvement, when the outside play of main string roller, fork 7,9 drive the secondary string of first string roller and one roller respectively, and inwardly string is moving, it is moving to the guest performer that the first string roller drives another secondary string roller by fork 4, at this moment, the play direction of two secondary string rollers is opposite, the moving direction of two strings in four copy rollers is inside, two copy rollers are outside in addition, at this moment, be applied to axial force on the plate cylinder by copy roller and cancel each other and be not subjected to responsive to axial force, the end play of plate cylinder can not increase and produce axial displacement, thereby eliminated the defective that printing has ghost image or ghost.
