Description
technical field [0001] The invention relates to the field of paper detection, in particular to a paper tension and deformation analyzer capable of dynamically detecting three-dimensional deformation of paper and automatically tracking and measuring three-dimensional deformation of paper. Background technique [0002] In addition to the printing system, the offset printing machine used for paper printing is also equipped with auxiliary components such as a paper tension adjustment system and an anti-winding device. During the paper feeding process, each part of the offset printing machine has a tension control unit, and the offset printing machine has a tight structure. Strong stability, the purpose is to ensure the accurate position of the paper and reduce deformation when the paper is fed. It can be seen that paper deformation has a great impact on registration. Accurate overprinting is a common quality requirement for all printed products, and it is also a precondition for...
