Description

Technical Field

[0001] The utility model relates to the technical field of film material composites, in particular to a device for improving the composite effect of film materials. Background Art

[0002] In recent years, with the rapid development of the new energy industry, the lithium battery diaphragm industry has also experienced an explosive growth period. At present, with the release of industry capacity, the competition in the industry has gradually intensified. High-efficiency and low-cost production methods have become an inevitable trend in the industry. Under this background, wide width and high speed have become the best choice for diaphragm production. Composite equipment is one of the key equipment in the diaphragm production process. Most of the existing composite equipment realizes the lamination of the film by means of composite roller and pressure roller. The air between different layers of materials is squeezed out by physical extrusion of composite roller and pressure roller, so as to achieve effective lamination of materials. However, due to the particularity of the film material, the pressure roller cannot be pressed too tightly, otherwise it is easy to cause wrinkles, marks and other undesirable conditions in the product. Under the production conditions of wide width and high speed, when the material is conveyed at high speed, it is easy to bring a large amount of air into the material. At the same time, the wide width of the material increases the difficulty of exhausting the air in the middle part. When the layers of materials are laminated, it is easy to have incomplete exhaust, resulting in air inclusion in the middle of the film, which will cause delamination, wrinkles, marks and other undesirable conditions in the subsequent products, resulting in product scrapping and increased production costs.

[0003] To this end, the utility model provides a device for improving the composite effect of membrane materials. Utility Model Content
