Description

Technical Field

[0001] This utility model relates to the field of fabric testing technology, and in particular to a high-efficiency inspection device for cylindrical fabrics. Background Technology

[0002] Cylindrical fabrics are generally produced by circular knitting machines. The fabric woven by these machines is cylindrical, so a splitting process is required during the finishing process to unfold the cylindrical fabric into a flat shape. To reduce creases after unfolding, the fabric is usually flattened and rolled up based on the pull-out stitch line during the rolling process, so that one end of the fabric roll is the pull-out stitch line and the other end is the crease line after flattening. During splitting, the cutter is usually made through the pull-out stitch line. To ensure fabric quality, after the splitting process, workers need to inspect the fabric for defects.

[0003] In existing inspection procedures, because the cylindrical fabric is flattened into a double-layered state, the existing flat-lay light transmission method can cause minor defects in the lower fabric to be blurred due to the influence of the two layers of fabric, which can easily lead to missed detections. This requires secondary verification, resulting in low inspection efficiency. To solve this problem, existing technology can use a limiting magnetic levitation float to support the cylindrical fabric and observe both sides through two reflective mirrors, allowing simultaneous viewing of both layers of fabric. However, this requires external light sources to illuminate the mirrors on both sides, which also poses a risk of missed detections when inspecting dark-colored fabrics, indicating room for further improvement.
