This invention relates to the field of welding fume purification technology, and discloses a welding fume purification system and method for memory module manufacturing. The welding fume purification system for memory module manufacturing includes a welding equipment body with several suction hoods symmetrically distributed on the body. A horizontal pipe is connected to the outlet of each suction hood, and a first vertical pipe is located at the bottom of the horizontal pipe. This welding fume purification system for memory module manufacturing extends the residence time of the fume in the first vertical pipe through staggered diversion plates, allowing it to fully contact the cooled pipe wall and initially reduce the fume temperature. This significantly slows down the oxidation reaction rate between metal oxides and the filter cartridge substrate, reducing the degree of filter cartridge corrosion and extending its service life. Simultaneously, the stable low-temperature environment prevents the filter cartridge from failing to seal due to thermal expansion and contraction, ensuring filtration accuracy while effectively preventing secondary pollution caused by leakage of unfiltered fume.

This utility model relates to a hemp feeding mechanism for a hemp combing machine, belonging to the field of hemp yarn processing. It includes a carrying body; a conveying mechanism located inside the carrying body; a guiding component located on the upper surface of the carrying body; and a cleaning mechanism located on the right side of the carrying body, comprising a mounting box located on the right side of the carrying body; a negative pressure module connected to the lower surface of the mounting box; and two pipes connected to the front and rear surfaces of the mounting box, with the other ends of both pipes penetrating the carrying body. Through the cleaning mechanism, this utility model utilizes the cooperation between the negative pressure module and the conical sleeve to automatically extract hemp fibers accumulated in the roller groove, preventing short fibers from converging and reducing the roller's gripping force, ensuring the roller is always in a highly efficient working state, reducing conveying failures caused by fiber accumulation, and improving the stability and reliability of the hemp feeding mechanism.
