Description

Technical Field

[0001] The utility model belongs to the technical field of PI film mask processing, and more specifically, particularly relates to an automatic PI film cutting device. Background Art

[0002] PI membrane mask is a protective mask with PI nanofiber filter membrane as the core filter layer. This mask mainly relies on physical interception and electrostatic adsorption to achieve efficient filtering effect. When producing and processing PI membrane masks, the PI membrane needs to be cut into a size suitable for the mask requirements. Therefore, a PI membrane automatic film cutting device is required. The existing PI membrane automatic film cutting device is mainly composed of a conveying mechanism, a positioning mechanism and a cutting mechanism. The conveying mechanism composed of a roller and a pressure roller is used to convey the PI membrane coil, and the PI membrane is positioned by a positioning mechanism such as a photoelectric sensor. After positioning, the PI membrane is cut to a suitable size using a cutting mechanism.

[0003] Based on the above, the existing PI film automatic film cutting device is prone to generate static electricity during the transportation process using the conveying mechanism. The static electricity of the PI film will absorb dust and impurities, affecting the quality and cleanliness of the PI film product. In addition, the static electricity of the PI film will cause adhesion problems after film cutting, making it inconvenient to stack the cut PI films flatly. In addition, the PI film may have wrinkles during the stacking process after cutting due to static electricity, uneven stacking, falling deviation, etc. If the wrinkles are not smoothed out in time and stacked, it will affect the product quality of the PI film after cutting.
