[0002] An automatic rolling filter is an air dust removal device that converts the pressure differential across the filter into an electrical sensor signal, automatically replacing the filter material. The winding structure of an automatic rolling filter is a key design feature, primarily used to automatically unfold and rewind the filter element. The winding structure primarily comprises a winding rod, filter element material, and a drive system.

[0003] The existing technology has the following deficiencies:

[0004] 1. The filter element material of the winding structure of the existing automatic rolling filter is usually rolled on a winding rod. Since the winding rod is usually difficult to remove from the corresponding mounting plate, it is often inconvenient to replace the entire roll of filter element material on the winding rod later.

[0005] 2. The winding rod of the winding structure of the existing automatic rolling filter is often affected by the tension when the filter element material is unfolded and reeled in. Therefore, the bearing strength of the winding rod itself is very important. The bearing strength of the winding rod of the winding structure of the automatic rolling filter can be further improved.
