Technical Field

[0001] The utility model relates to the technical field of screen processing, and more specifically, to a medical chromatography column filtering screen edge pressing device. Background Art

[0002] Pharmaceutical chromatography columns are the main body of gel chromatography technology. They are generally made of glass tubes or plexiglass tubes. They are a type of chromatography that separates components in the sample mixture based on their different distribution coefficients in the stationary phase and the mobile phase. Filter screens are usually used when filtering pharmaceutical chromatography columns. Screen filtration is widely used on pharmaceutical chromatography columns, and more and more customers are demanding edge sealing of the screens.

[0003] During the edge sealing process of the screen, whether it is through laser welding or argon arc welding, heat will be generated to cause the screen to deform to varying degrees. After welding, it needs to be leveled again, resulting in low edge sealing efficiency. During the simultaneous welding process, the molten iron of the welding wire and the screen will flow irregularly, which will cause irregular welds. Utility Model Content
