[0002] CO2 separation membrane refers to a gas separation membrane that can separate carbon dioxide from a mixed gas. Carbon dioxide is a condensable gas with strong polarization and a relatively large solubility coefficient in membrane materials, so the permeability coefficient and separation coefficient are also relatively large. Generally, almost all membrane materials with good oxygen permeability can be used as oxygen-rich membranes to separate carbon dioxide. When producing and processing CO2 separation membranes, membrane cutting equipment is required to cut them.

[0003] For example, the utility model with application number CN202120446705.1 discloses a roll film cutting machine. The platform lifting mechanism described in the utility model can enable the utility model to quickly adapt to external processing equipment at different heights without spending more time and energy or other external equipment for adjustment, which greatly improves work efficiency. However, in the actual lifting and adjustment process of this type of film cutting equipment, since the cylinder and column of its cutting platform are slidingly connected, it can only play a limiting role, resulting in weak support force at the bottom four ends of the cutting platform and general overall stability.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a membrane cutting device for CO2 separation membrane that is easy to adjust is provided. Utility Model Content
