Abstract: A pole piece manufacturing device is described. The pole piece manufacturing device includes a membrane forming mechanism, a composite mechanism, a detection mechanism and an adjustment mechanism. The membrane forming mechanism is configured to form an active substance into a membrane. The composite mechanism is configured to composite the membrane and a substrate into a pole piece. The detection mechanism is is configured to detect a thickness or a weight per unit area of the membrane. The adjustment mechanism is configured to adjust the membrane forming mechanism according to detection results of the detection mechanism, so as to control the thickness or the weight per unit area of the membrane within a preset range. The membrane is detected by providing the detection mechanism. When the membrane does not meet the design requirements, the membrane forming mechanism is adjusted timely through the adjustment mechanism to make it meet the design requirements.

Abstract: A drying apparatus for drying a material belt includes at least one material-belt turning mechanism, used for changing a travel direction of the material belt, and including a first passing roller, a turning roller, and a second passing roller sequentially arranged in the travel direction of the material belt. The turning roller is configured to move in a first direction relative to the first passing roller and the second passing roller to adjust a wrap angle of the material belt on the turning roller, the first direction perpendicular to an axial direction of the turning roller.
