A horizontal printing height difference correction device for a color printing machine

Abstract

The invention provides a horizontal printing height-difference deviation correcting device for a color printing machine. The horizontal printing height-difference deviation correcting device comprisesa support, deviation correcting mechanisms, conveying rollers, height-difference measuring mechanism, sliding blocks and first supporting springs, wherein the two sliding blocks are movably arrangedon the support, the two ends of one of the two conveying rollers are installed on the support through bearings, the two ends of the other conveying roller are arranged on the two sliding blocks through bearings respectively, the two deviation correcting mechanisms are located on the two sides of the conveying rollers, and the four height-difference measuring mechanisms are arranged on the supportcorrespondingly. The actual value of the height difference can be accurately measured through the height-difference measuring mechanisms arranged beside the two conveying rollers; and the height of the conveying rollers is finely adjusted through the deviation correcting mechanisms, so that the angle of printing materials in the printing device can be directly adjusted, the relative level betweenthe printing materials and a nozzle can be kept, and the adverse effects caused by high difference of the materials to printing can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of printing equipment, in particular to a horizontal printing height difference correction device for a color printing machine. Background technique [0002] The color printing machine adopts modular product accessories, and directly prints the graphics and text on the computer on the printing medium through the nozzle of the inkjet printer. Its operation is simple and convenient, the printing speed is fast, the printing cost is low, and the limit of the material is overcome. However, during the printing process, due to material deviation, mechanical vibration or inaccurate feeding, etc., the nozzle of the inkjet printer cannot spray ink well on the area to be printed, and inkjet is prone to occur after printing. For quality problems such as shade and color difference, if a deviation correction device is installed on the equipment, the impact of the above phenomena can be effectively corrected. [0003] Pub...

AI Technical Summary

Problems solved by technology

Since the printing material tends to be uneven when it moves to the position of the nozzle when the printing material is being printed, and this correction method only changes the distance between the nozzle and the surface to be printed, and cannot eliminate the gap between the nozzle and the printed material. Therefore, it is impossible to make the nozzle and the printing material in a relatively parallel state, and the printed material is prone to quality problems such as inkjet density and color difference
