Description

Technical Field

[0001] The utility model relates to the technical field of textile production and processing, in particular to an air leakage and dust filtering mechanism for a pre-opening cotton machine. Background Art

[0002] The pre-opening machine is a device used for cotton processing. Its main function is to conduct preliminary opening of dense raw cotton through different rollers and wire combs to make the raw cotton loose and gradually separate the cotton wool to make it suitable for subsequent spinning processing.

[0003] The pre-cotton opening machine in the prior art is generally composed of an air discharge and dust filtering mechanism, an exhaust pump, a connecting pipe, a cotton grabbing and loosening machine, a conveyor belt, etc. When in use, the exhaust pump is started to form a negative pressure inside the installation box, so that the dust and impurities inside the cotton can enter the filter box, thereby making the output cotton of higher quality.

[0004] However, in actual use, since the cotton is relatively fluffy after opening, part of the cotton will be adsorbed to the lower side of the filter box, which will block the aperture of the filter box, and thus affect the adsorption efficiency of dust and impurities inside the cotton. Therefore, workers will use a screwdriver to remove the bolts on the filter box to clean the filter box. Since the filter box is installed inside the installation box, it is inconvenient for workers to operate, which will affect the dust filtering efficiency of the cotton. Utility Model Content
