Description

Technical Field

[0001] The utility model relates to the technical field of air filter cotton, in particular to an air filter cotton detection device. Background Art

[0002] Air filter cotton is a core component in air filtration systems. During the production process, the filter cotton undergoes multiple tests before cutting and assembly. To ensure the performance stability of the filter cotton, wind resistance testing, thickness measurement, and uniformity testing are required before cutting and assembly. One of the most critical tests is the airflow resistance test. This test ensures that the filter cotton will not affect air flow during use and that its filtration efficiency and flow rate meet design requirements.

[0003] Current air filter cotton testing equipment on the market requires cutting a portion of the filter cotton for separate testing and securing it with a clamp when performing windage testing. This not only wastes material but also fails to ensure that the test results accurately reflect the actual performance of the entire filter cotton sheet. Testing a cut filter cotton sheet can overlook the actual performance of certain areas, affecting the overall filter performance evaluation. Therefore, there is a need for an air filter cotton testing device that addresses these technical limitations. Utility Model Content
