Description

Technical Field

[0001] The utility model relates to a fixing device for real-time detection of non-woven fabric defects, belonging to the technical field of devices for non-woven fabric detection. Background Technique

[0002] Non-woven fabric, also known as non-woven cloth or non-woven fabric, is a sheet, web or batt made by bonding, fusing or entangling fibers in a random or oriented manner, or a combination of these methods. It is a fabric formed without spinning and weaving, by simply arranging short textile fibers or filaments in a random or oriented manner to form a web structure, and then strengthening it by mechanical, thermal bonding or chemical methods. During the detection of non-woven fabric defects, a fixing device is required to fix it.

[0003] According to the patent with the publication number CN212586229U, a cloth defect detection device is disclosed. The cloth defect detection device includes a machine table, a support mechanism, a multi-directional movement mechanism, a lighting mechanism, an image acquisition mechanism and a flattening mechanism. The support mechanism is arranged on the machine table and has a support plate for supporting the cloth. The multi-directional movement mechanism is installed on the machine table and can move in multiple directions. The lighting mechanism and the image acquisition mechanism are both arranged on the machine table. The flattening mechanism has a flattening rod, and the flattening rod is rotatably installed on the multi-directional movement mechanism and cooperates with the support plane of the support plate to flatten the cloth on the support plane. This cloth defect detection device can be used for defect inspection of cloth, saving time, reducing dependence on people, and having a high cloth inspection efficiency. After fixing the non-woven fabric, the above device still needs to use the flattening mechanism to flatten the non-woven fabric and then perform detection. Therefore, the flattening effect of the non-woven fabric is poor, which may affect the accuracy of the detection result. Content of the Utility Model
