Automatic deviation correcting device and automatic deviation correcting gravure printing machine

Abstract

The invention discloses an automatic deviation correcting device which comprises a deviation correcting bracket and a deviation correcting mechanism, wherein the deviation correcting mechanism is fixed on the deviation correcting bracket. The deviation correcting mechanism consists of a control system and a deviation correcting system, the control system is fixed on the upper surface of the deviation correcting support, the deviation correcting system is arranged below the deviation correcting bracket, and the control system is electrically connected with the deviation correcting system. The invention also discloses an automatic deviation correcting gravure printing machine. The automatic deviation correcting gravure printing machine solves the technical problem that the high-speed code setting sleeve position is not accurate in the industry, improves the product percent of pass, reduces the production cost, improves the working efficiency, reduces the adverse products, achieves the environmental protection and low carbon, saves the social resources, and applies to printing in tobacco package industry, printing in cosmetic industry, printing in medicine industry, printing in foodindustry and the like.

Description

technical field [0001] The invention belongs to the technical field of gravure printing, and in particular relates to an automatic deviation correction device and an automatic deviation correction gravure printing machine. Background technique [0002] During the printing process of the printing machine, due to the influence of many factors such as printing speed, tension, the relative sliding of the guide roller and the pressure roller, and the elastic shrinkage of the printing material, the deviation of the printing position, especially the overprinting position, leads to the running of the version. To a certain extent, the printing cost has been increased. Therefore, it is necessary to monitor the printed materials during the printing process to correct errors and improve printing registration accuracy. At present, domestic printing machines usually use manual deviation correction when printing color printed matter, that is, the printing workers regularly check the print...

AI Technical Summary

Problems solved by technology

This method has the following defects: 1. The printing speed is low. This is because manual inspection is already done reluctantly at low speeds. Manual inspection and correction during high-speed printing can no longer meet the accuracy requirements for correction, resulting in the inability to form large-scale production; 2. The color registration deviation is manually adjusted, which makes it difficult to ensure consistent product quality, which inevitably leads to an increase in the scrap rate, an increase in production costs, and a decline in the market competitiveness of the product

[0003] Especially in the cigarette case printing process, after the layout is printed, it is necessary to assign codes at the end. During the code assignment process of the existing equipment, due to the instability of the paper feeding, the left and right deviations, and the influence of the tension swing, the paper is horizontally overlapped. The position is inaccurate, the position deviation is large, more waste products are produced and the customer requirements cannot be met, the product quality is not guaranteed, and the production cost rises
