High-precision stepping paper feeding movement system suitable for plotter and paper feeding control method

Abstract

The invention relates to a high-precision stepping paper feeding movement system for a plotter and a paper feeding control method. The system comprises a roll paper mounting mechanism, a paper conveying mechanism, a paper feeding mechanism and a driving control system; the roll paper mounting mechanism is used for mounting roll paper and unfolding and guiding the free end of the roll paper to the paper conveying mechanism; the paper conveying mechanism is used for conveying paper to the paper feeding mechanism; the paper feeding mechanism is used for outputting paper; the driving control system is used for controlling the paper conveying speed and the paper feeding speed; a paper tension state detection sensor is arranged on one side of the paper between the paper conveying mechanism and the paper feeding mechanism; a paper limit relaxation state detection sensor is arranged on the other side of the paper; and a paper head position measuring sensor is arranged at the front end of output paper of the paper feeding mechanism. The paper feeding precision is improved, and the high-precision printing application requirement is met.

Description

technical field [0001] The invention belongs to the technical field of plotters, and in particular relates to a high-precision stepping paper-feeding motion system and a paper-feeding control method suitable for plotters. Background technique [0002] As a computer output device, a plotter is mostly inkjet printing, and is mainly used to draw various surveying drawings, architectural design drawings, wiring diagrams, and photo images. As plotters are gradually used in topographic maps, aerial maps, The output of coastal charts and high-precision image data requires higher and higher printing accuracy of plotters. It is difficult for ordinary plotters to meet the accuracy requirements of such applications. [0003] The output accuracy of the plotter is mainly determined by the accuracy of the print head itself, paper feeding accuracy, and scanning positioning accuracy. Among them, the paper feeding accuracy is affected by paper characteristics, friction transmission and stepp...
