Description

Technical Field

[0001] The utility model relates to the technical field of filter bag processing, in particular to a filter bag folding machine. Background Art

[0002] The bag dust collector is a dry dust filtering device that is suitable for capturing fine, dry, non-fibrous dust. The filter bag is made of textile filter cloth or non-textile felt, and uses the filtering effect of fiber fabric to filter the dust-laden gas. When the dust-laden gas enters the bag dust collector, the dust with large particles and high specific gravity settles down due to gravity and falls into the ash hopper. The gas containing finer dust is retained when passing through the filter material, so that the gas is purified.

[0003] In the prior art, filter bags are folded mainly by manual folding one by one. This method is not only labor-intensive and easy to cause waist strain to the operators, but also due to errors in manual operation, the specifications of the folded filter bags are not the same, resulting in differences in product appearance. Therefore, a filter bag folding machine is needed. Utility Model Content
