Membrane flattening device

Abstract

The invention discloses a membrane flattening device, which comprises a shell, a transmission mechanism and a flattening mechanism. The lower part of the shell is open; the transmission mechanism is mounted in the shell; the flattening mechanism is in driving connection with the transmission mechanism; and the movement direction of the transmission mechanism is perpendicular to the membrane transporting direction. The certain pressure is applied to membranes during winding, the membranes are stretched left and right to be flattened, and the membrane flattening device can be used for flatteningof isolation membranes of lithium-ion batteries, and flattening and extending of copper foil, aluminum foil and the isolation membranes of the lithium-ion batteries, and can also be used for flattening and extending of membranes of the papermaking industry, the plastic membrane industry and the like.

Description

technical field [0001] The invention relates to the technical field of medium and medium machinery, in particular to a membrane material smoothing device. Background technique [0002] Membranes and foils generally refer to a type of material with a small thickness, a large width, and a long length. This type of material often needs to be wound on a core when sorting and collecting, but due to production technology or tension adjustment The reason is that the thickness of the membrane material in the width direction is often uneven, and under the action of tension during sorting and collection, the smaller and larger thicknesses will cause wavy patterns on the drum, which are called "burst ribs" in the industry. Since the isolation film coil is often larger than 1000 meters, the defects inside the coil cannot be found. Therefore, it is necessary to smoothen the film material during winding to reduce the defects generated during winding. Contents of the invention [0003]...
