The purpose of the invention can be realized by the following technical scheme: the utility model provides a mounting structure of printing roller and galley, a serial communication port, a mounting groove has been seted up on printing roller global, two straight terminal surfaces of printing roller are run through at the both ends of mounting groove, two spacing notches that have symmetric distribution in the mounting groove, every spacing notch all corresponds a compression roller, the both ends of compression roller are rotated respectively and are connected with a swing arm, the swing arm articulates on printing roller's straight terminal surface, spacing notch is the arc curved surface with the global adaptation of compression roller, the both ends of galley are sticis in the spacing notch that corresponds with the compression roller through two compression rollers respectively, are connected with a pressure spring under the compression state between two swing arms on same printing roller's the straight terminal surface.
In the above-mentioned mounting structure for the printing roller and the printing plate, a circumferential surface of one of the pressing rollers has spiral convex ribs, and a circumferential surface of the other pressing roller is alternately provided with a plurality of annular convex ribs, and the convex ribs are coaxial.
In the above-mentioned mounting structure of printing roller and printing plate, the compression roller is a rubber roller, and the convex strip and the convex rib are integrally formed with the corresponding compression roller.
In the above installation structure of the printing roller and the printing plate, the middle part of the press roller is provided with a plurality of jacks penetrating through the peripheral surface of the press roller, and a phase angle is arranged between adjacent jacks on the same press roller.
When the printing plate is installed, after the printing plate is tiled, the two swing arms at the same side of the printing roller are clamped by the clamp, so that the two press rollers are close to each other, a space allowing the end part of the printing plate to enter the limiting notch is vacated, and after the initial positioning of the printing plate is completed, the clamp is slowly released, so that the end part of the printing plate is clamped in the press rollers and the limiting notch; the straightness of inspection printing plate, the rate of tension, if there is the printing plate dislocation, when the straightness of relative printing roller exists the deviation promptly, insert in the jack through shaft-like instrument such as spanner, carry out phase adjustment to the compression roller that has the protruding muscle of spiral on global, make the printing plate tip that is sticis by this compression roller can take place less displacement in the axis direction of compression roller, thereby the straightness of adjustment printing plate, the not ideal condition of printing plate rate of tension that still needs the inspection printing plate probably exists, carry out the rotation of minimumly to the compression roller that global is provided with the sand grip through same method, make the printing plate carry out the rate of tension and adjust under the condition that keeps the straightness.
This mounting structure, its simple structure, the dismouting galley is very light, and can carry out light regulation to the straightness and the rate of tension of galley, has improved the installation accuracy greatly.

Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
As figure 1, figure 2, figure 3 and figure 4 show, a mounting groove 21 has been seted up on printing roller 2 global, two straight terminal surfaces of printing roller 2 are run through at the both ends of mounting groove 21, two spacing notches 211 that have symmetric distribution in the mounting groove 21, every spacing notch 211 all corresponds has a compression roller 3, the both ends of compression roller 3 are rotated respectively and are connected with a swing arm 4, swing arm 4 articulates on printing roller 2's straight terminal surface, spacing notch 211 is the arc curved surface with the global adaptation of compression roller 3, the both ends of printing plate 1 are sticis in the spacing notch 211 that corresponds with compression roller 3 through two compression rollers 3 respectively, be connected with a pressure spring 5 under the compression state between two swing arms 4 on same printing roller 2's the straight terminal surface.
The circumferential surface of one of the compression rollers 3 is provided with spiral convex ribs 31, the circumferential surface of the other compression roller 3 is alternately provided with a plurality of annular convex ribs 32, and the convex ribs 32 and the compression roller 3 where the convex ribs 32 are located are coaxial. The press rollers 3 are rubber rollers, and the convex strips 32 and the convex ribs 31 are integrally formed with the corresponding press rollers 3.
The middle part of the press roll 3 is provided with a plurality of insertion holes 33 penetrating through the circumferential surface of the press roll 3, and a phase angle is arranged between the adjacent insertion holes 33 on the same press roll 3.
When the printing plate 1 is installed, after the printing plate 1 is tiled, the two swing arms 4 on the same side of the printing roller 2 are clamped by the clamp, so that the two press rollers 3 are close to each other, a space allowing the end part of the printing plate 1 to enter the limiting notch 211 is vacated, after the initial positioning of the printing plate 1 is completed, the clamp is slowly released, and the end part of the printing plate 1 is clamped in the press rollers 3 and the limiting notch 211; the straightness and the tension of the printing plate 1 are checked, if the printing plate 1 is dislocated, namely, when the straightness of the printing roller 2 deviates, a rod-shaped tool such as a wrench is inserted into the insertion hole 33 to perform phase adjustment on the pressing roller 3 with the spiral convex rib 31 on the peripheral surface, so that the end part of the printing plate 1 pressed by the pressing roller 3 can generate small displacement in the axis direction of the pressing roller 3, the straightness of the printing plate 1 is adjusted, the condition that the tension of the printing plate 1 is not ideal, which possibly exists in the printing plate 1, is also checked, the pressing roller 3 with the convex rib 32 on the peripheral surface is rotated in a small range by the same method, and the tension of the printing plate 1 is adjusted under the condition of keeping the straightness.
