Description

TECHNICAL FIELD

[0002] Microporous filter membrane is made by using high molecular chemical material, and pore-forming additive is coated on support layer after special treatment. In the application of membrane separation technology, microporous filter membrane is the most widely used membrane variety, which is simple, fast and widely used in scientific research, food detection, chemical industry, nanotechnology, energy and environmental protection and many other fields. Microporous filter membrane is mainly made of refined nitration cotton, and a proper amount of cellulose acetate, acetone, n-butanol, ethanol and the like. It is hydrophilic, non-toxic and sanitary, and is a porous thin film filtration material. The pore size distribution is relatively uniform, and the absolute pore size of the microporous rate is as high as 80 ‰. It is mainly used for filtering aqueous solution, so it is also called aqueous membrane.

[0003] During its production process, the parent roll needs to be cut into several groups of sub-rolls according to process requirements. However, since the roll diameter of the parent roll is usually larger than that of the sub-rolls, when the roll diameter of the sub-rolls reaches the set value during the cutting process, the filter membrane in the cutting machine needs to be cut. However, due to the smooth surface of the filter membrane, it will slide off the guide roller under the action of gravity, so the operator needs to guide and wind the filter membrane on the cutting machine again during cutting, which greatly wastes time and affects cutting efficiency.
