Description

Technical Field

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

[0002] The main fiber raw material of non-woven fabrics is polypropylene fiber (polypropylene), but it is not the only raw material. Polyester fiber (polyester), polyamide fiber, polyacrylonitrile fiber, viscose fiber, etc. can all be used to produce non-woven fabrics. In addition to the above chemical fibers, natural fibers such as cotton, hemp, wool, and silk can also be used to produce non-woven fabrics. During the production process of non-woven fabrics, it is necessary to detect the surface defects.

[0003] According to the patent with the publication number CN212077430U, a non-woven fabric surface defect detection device is disclosed, including a mounting frame. A traction roller is fixedly installed in the middle of the mounting frame. Anti-static blocks and compaction blocks are staggered on the outer side of the traction roller. A non-woven fabric is movably connected between the traction rollers. Mounting plates are respectively fixedly installed at the upper and lower ends of the mounting frame. A waste box is fixedly installed on the left side of the mounting plate. An exhaust fan is fixedly installed on the front of the waste box. Through the anti-static blocks and compaction blocks staggered on the traction roller, the non-woven fabric can pass through the detection device stably and efficiently. And through horizontal detection and vertical detection, the all-round detection of the non-woven fabric is realized, greatly improving the detection accuracy, ensuring the stable and efficient production of non-woven fabrics, thus improving the production quality of non-woven fabrics, and improving the rationality and reliability of the device. When the above device is in use, although it can clean the non-woven fabric, after the cleaning brush is used for a long time, since a large amount of dirt will adhere to the cleaning brush, it will affect the cleaning effect of the non-woven fabric. At this time, it is also inconvenient to disassemble, clean and replace the cleaning brush, resulting in low practicability of the device. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a real-time detection device for surface defects of non-woven fabrics. The utility model can facilitate the disassembly and assembly of the cleaning mechanism, thus facilitating the cleaning and replacement of the cleaning mechanism, avoiding affecting the detection effect, and thus improving the practicability of the device, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:
