Non-woven fabrics are a new generation of environmentally friendly materials with the advantages of good strength, breathability and waterproofness, environmental protection, flexibility, non-toxicity and tastelessness, and low price. Facial masks made of non-woven fabrics have good performance, but stains on non-woven fabrics will directly affect product sales.

[0033] The utility model provides a non-woven fabric stain detector, and the specific working principle is as follows: first, a water source for marking is injected into the water tank 26 of the marking mechanism, and then the fabric is introduced into the light shielding box 2 on the workbench 1 through the conveying mechanism, and the fabric is introduced and discharged through the fabric seam 4 on the light shielding box 2;

[0034] At the same time, the detection mechanism completes the continuous stain detection work on the cloth without human intervention. When the detection mechanism detects the stain on the cloth, the control console controls the electric push rod 16, and the electric push rod 16 pulls the marking strips 25 on both sides of the light-shielding box 2 to move down toward the support plate 21 until the cloth is squeezed between the two, and then the water source carried by the marking strips 25 is used to form water marks on the cloth. Therefore, after the stain is detected, the marking mechanism is used to complete the synchronous marking work on both sides of the workbench 1, and then two parallel water marks are formed on the cloth. The subsequent staff can cut the cloth accordingly according to the water mark area. At the same time, the marking mechanism can fine-tune the spacing between the two marking strips 25, and can form water marks in different width ranges, which can be adjusted freely, saving time and effort, and improving the detection efficiency.
