Description

Technical Field

[0001] This utility model relates to the field of fabric inspection technology, specifically a fabric inspection machine for polyester filament spinning quality inspection. Background Technology

[0002] Fabric inspection machines are specialized equipment used in the garment and textile industries to inspect the quality of fabrics. They can detect defects and color differences, and complete length recording and roll finishing. Their basic structure includes a fabric unwinding and winding device, an inspection table and light source, and a code recording device. There are various types, such as intelligent fabric inspection machines that use cameras to automatically detect defects and are suitable for solid-color knitted fabrics; digital semi-automatic fabric inspection machines can record the coordinates of defects and generate reports. Their working principles are divided into two types: manual visual inspection and automatic image analysis. They are widely used in textile factories, garment factories, and fabric trading companies, helping companies control fabric quality, reduce problems in production and trade, and improve efficiency and quality stability.

[0003] Currently, when conducting quality inspection on polyester filament fabrics, a fabric inspection machine is required to inspect the polyester filament fabrics produced during production, and to detect defects, color differences, and other issues on the fabric. When using the fabric inspection machine, the polyester filament fabric needs to pass over an LED light panel, and then a high-pixel camera is used to capture the fabric image to detect fabric defects. However, there may be debris on the surface of the fabric during production. When passing over the LED light panel, it falls onto the light panel, which can cause uneven lighting, reduced brightness in some areas, or shadows. This will affect the accuracy of the fabric inspection machine in identifying polyester filament fabrics. Utility Model Content
