Description

Cloth inspection device with tension tightness adjusting function and cloth inspection method Technical Field The invention relates to the technical field of cloth inspection, in particular to a cloth inspection device with a tension tightness adjusting function and a cloth inspection method. Background In cloth production, a cloth inspection process is a key link for ensuring the quality of a finished product. Products with defects such as defects and chromatic aberration can be found and removed in time by systematically inspecting the cloth, so that the factory cloth is guaranteed to meet quality standards, when the cloth is inspected, the cloth to be inspected is pulled by the winding roller at a constant speed to pass through the cloth inspection area, moderate tension is maintained on the cloth through the tensioning structure during the process, and the cloth is illuminated by a sufficient light source, so that operators or an automatic optical detection system can conveniently inspect the condition of the cloth section by section, and various defects can be accurately identified. The core purpose of keeping certain tension of the cloth in the inspection process is to avoid covering defects such as local defects, chromatic aberration and the like caused by the cloth cover folding, so that a detection blind area is formed, however, in the practical cloth inspection work, folding problems can still be caused by factors except excessive tension, such as width-direction tension loss and uneven release of residual stress in the cloth, which can cause unnecessary folding of the cloth cover in the detection area, so that the accuracy of cloth inspection is seriously affected. In this regard, the partial cloth inspecting device adopts the wrinkle removing measure, and spreads the cloth in the width direction through the arc roller, the spiral cloth spreading roller, the airflow smoothing device or the like, but it is worth noting that if the cloth maintains the original longitudinal tension unchanged at this time, excessive stretching and deformation of the cloth can be caused under the bidirectional stress state, and the original texture structure and defect morphological characteristics of the cloth can be possibly changed, so that the defect recognition difficulty is increased, and the reliability of the detection result is affected.
