Abstract

The invention discloses a novel online detection device and detection method for the surface flatness of paper ream of an anti-counterfeit paper, and relates to the technical field of quality detection equipment. The device comprises a comprehensive adjusting table and a flattening detector, a solenoid coil and a sliding contact block are arranged in the flattening detector and form a sliding rheostat structure, and a roller in the flattening detector and a conveying belt in the comprehensive adjusting table are both in contact with paper reams and extrude each other. According to the invention, the solenoid coil, the sliding contact block, the roller and the conveying belt are arranged, a basic sliding rheostat working principle is utilized, mechanical signals and electric signals are directly converted, and the flatness of the surface of paper ream can be detected more conveniently; wherein the roller and the conveying belt are used for pressing the paper ream, so that the detection result is more accurate, the slide rheostat structure can be directly replaced by the existing potentiometer and the like, the cost of the whole device is lower, and the whole detection cost is reduced while the detection accuracy is ensured.

Description

technical field [0001] The invention belongs to the technical field of quality testing equipment, and in particular relates to a novel anti-counterfeiting paper ream surface smoothness online testing device and testing method. Background technique [0002] Anti-counterfeiting paper is generally used in the production of various anti-counterfeiting marks, banknotes, commemorative coins, etc., and the anti-counterfeiting function is mainly realized by engraving various grooves or embedding metal wires on the surface or inside; In the past, when there were quality problems such as uneven surface flatness, it was easy to cause difficulties in actual printing, thereby affecting the quality and efficiency of processing and production. Therefore, in the existing technology, the flatness of the paper ream is often tested after the processing and production of anti-counterfeiting paper; and Most of the existing detection devices use various sensors. Although they are accurate, the ov...
