Adsorption roller for continuous printed matter detection and adjusting method for conveyed printed matter

Abstract

The invention discloses an adsorption roller for continuous printed matter detection and an adjusting method for a conveyed printed matter. Angle sensors are embedded in adsorption roller bearing wheels; proximity sensors are installed on outer surfaces on two sides of a roller body; the angle sensors and the proximity sensors control electromagnetic valves to act by controllers and drivers which are arranged in the roller body; the adsorption roller is internally provided with a wireless communication module and a built-in battery; at least two annular electric conductive loops are embedded on the end surface at one side of the adsorption roller by an insulation band at intervals; paper is subjected to dynamic tensioning, absorption fixation, prefixing to releasing and single-side adsorption angle adjustment by feedback signals of the sensors. According to the invention, because continuous conveying stability is realized, detection of only samples in a laboratory is successfully expanded to continuous and comprehensive detection of printed matters, so that the quality detection reliability and quality detection efficiency of laser printed matters are improved greatly.

Description

Technical field [0001] The present invention relates to printing or optical inspection equipment, in particular to provide a suction roller for continuous inspection of printed matter for continuous inspection of printed matter and a method for adjusting the conveyed printed matter. Background technique [0002] At present, in terms of packaging paper materials, laser paper printing is usually used to show colorful effects. The rainbow light effect contained in this type of paper can reflect different rainbow rays when observed at different angles. Printing on this paper has Good visual expression, giving people a pleasing feeling. However, it is the dazzling effect of this laser that brings great difficulties to the hue detection of printing, because the background color of this laser paper is greatly different under different light sources, and this difference is under the interference of laser light. , It is easy to cause color cast of printed products. The existing detectio...

Problems solved by technology

[0003] Existing laser paper extinction detection can only stay in the laboratory to detect samples, and when it is applied to the production line, it will face the instability and wrinkle of the measured object caused by vibration and paper movement during the continuous transmission of large quantities of laser paper. Problems such as pleats, uncertain positions, and unstable local angles of the paper cause inaccurate sampling and cannot be compared with standard samples, so it is difficult to continuously monitor extinction in actual production

[0004] In the process of solving this problem, it is found that one of the problems that limits the continuous transmission and detection speed of the paper is that in the process of rapid transmission, the paper may appear deflection in addition to the jumping phenomenon, so for the detection point of the continuous transmission of the paper to be inspected Stable and accurate need to give a specific solution
