Description

Technical Field

[0001] The utility model relates to the technical field of battery diaphragm production equipment, and more specifically, to a diaphragm flatness regulating device. Background Art

[0002] In recent years, with the development of the lithium-ion battery separator industry, people's requirements for the output and quality of lithium-ion battery separators are also constantly increasing. When the separator passes through the preheating oven, since the preheating oven is in the heating process, if there is an uneven membrane surface during the movement of the separator, after being heated in the preheating oven, wrinkles will be left on the membrane surface, resulting in poor coating after the separator is coated. The existing flattening mechanism cannot effectively flatten the separator due to problems such as the adjustment range and the force angle. As a result, the membrane surface is uneven during the movement of the separator. In order to solve the problem of wrinkles and poor coating caused by wrinkles on the separator after passing through the preheating oven; we provide a separator flatness adjustment device, which controls the flatness of the membrane surface through a two-way linkage clamping roller.
