Description

Technical Field

[0001] The utility model belongs to the technical field of hollow fiber curtain membranes, and in particular relates to a cutting device for hollow fiber curtain membranes. Background Art

[0002] Hollow fiber membrane refers to a self-supporting membrane with a fiber-like appearance. Hollow fiber membrane is made of polysulfone and dimethylacetamide as raw materials, processed into a fiber with a hollow inner cavity, and then divided by a high permeability polymer. It has selective permeation characteristics. Since water vapor, hydrogen, ammonia and carbon dioxide permeate faster, while methane, nitrogen, argon, oxygen and carbon monoxide permeate slower, the fast permeating and slow permeating are separated. Due to its high separation capacity and large specific surface area, hollow fiber curtain membrane plays an important role in various filtration and separation operations.

[0003] However, in the production process of hollow fiber curtain membranes, the cutting operation is a key step, which has an important impact on its quality and performance. During the cutting process, due to the softness and lightness of the hollow fiber curtain membrane, it is easy to displace on the cutting table. This not only affects the cutting accuracy, but also may cause damage to the membrane and reduce the qualified rate of the product. During the cutting process, the hollow fiber curtain membrane may bend and deform due to its own tension and cutting force, which not only affects the straightness of the cutting, but also may cause damage to the internal structure of the membrane and affect its performance. For this reason, we design a cutting device for hollow fiber curtain membranes to provide another technical solution to the above technical problems. Utility Model Content
