AI Technical Summary
Existing composite air filter cotton processing equipment lacks an effective smoothing structure during the winding process, which prevents the release of tiny surface undulations, resulting in wrinkles. At the same time, it is difficult to accurately limit the width of filter cotton of different specifications, resulting in irregular product shapes.
By employing a limiting component, a width adjustment component, and a smoothing component, and through the combined use of the limiting plate and the smoothing roller, precise positioning and surface smoothing of the composite air filter cotton are achieved, ensuring a smooth winding process.
This effectively prevents the composite air filter cotton from shifting position and wrinkling during the winding process, ensuring the neatness and quality of the product appearance and improving production efficiency.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of air filter cotton processing technology, specifically a composite air filter cotton processing equipment. Background Technology
[0002] As people's requirements for air quality continue to increase, air filter cotton is being used more and more widely in the field of air purification. Composite air filter cotton is favored by the market because it has multiple filtration functions, high filtration efficiency, and long service life.
[0003] In actual production, existing composite air filter cotton processing and winding equipment suffers from several drawbacks. During the winding stage, the equipment lacks an effective smoothing structure. After the composite and cutting processes, the cotton directly enters the winding mechanism, leaving no residual surface undulations or stress. As winding continues, these minor unevennesses accumulate, eventually leading to noticeable wrinkles in the wound composite air filter cotton. Furthermore, existing winding equipment struggles to precisely limit the width of composite air filter cotton of different specifications. During winding, the filter cotton is prone to lateral displacement due to external interference or uneven conveying speed. This displacement results in irregular roll shapes, affecting the product's appearance. These factors limit the high-quality production and efficient processing of composite air filter cotton, failing to meet current demands. Utility Model Content
