The invention relates to the technical field of
textile fabric detection, in particular to a defect detection device for
textile fabric
processing, which comprises a rack, a first conveying roller
assembly and a second conveying roller
assembly, the first conveying roller
assembly comprises a first top conveying piece rotationally arranged at the top of the rack and a first bottom conveying piece rotationally arranged at the bottom of the first top conveying piece. The second conveying roller assembly can slide along the rack and is matched with the linkage control of the elastic supporting piece, the photoelectric proximity switch and the
metal plate induction piece, the fabric tension degree can be automatically adjusted, the
moving speed of the fabric is kept consistent with the rotating speed of the conveying rollers through the transmission fit of the driving motor and the conveying rollers, and the fabric tension degree can be automatically adjusted. The fabric between the first conveying roller set and the second conveying roller set is always in a proper tensioning state, wrinkles caused by fabric looseness are avoided, and the defect detection accuracy is further improved.
