Abstract

The invention discloses a pole-piece hot-roll drying system. The pole-piece hot-roll drying system comprises an unwinding module, a hot roll drying furnace module, a driving module and a winding module, wherein the unwinding module is provided with an unwinding rectification assembly, an unwinding swing roll and an unwinding pressure-belt platform assembly; a pole-piece base band passes through the unwinding rectification assembly, the unwinding swing roll and the unwinding pressure-belt platform assembly sequentially, and then enters the hot roll drying furnace module; the hot roll drying furnace module is provided with a plurality of hot rolls; the hot rolls are separately connected with a mold temperature controller; the pole piece base band passes through the hot rolls sequentially and then enters the driving module; the driving module is provided a driving steel roll and a rubber-covered roll; the pole-piece base band is tightly pressed on the driving steel roll by the rubber-covered roll, and then enters the winding module; the winding module is provided with a winding rectification assembly, a winding swing roll and a winding pressure-belt platform assembly; and the dried pole-piece base band passes through the winding rectification assembly, the winding swing roll and the winding pressure-belt platform assembly sequentially, and then enters a pole piece winding shaft. Through the adoption of the pole-piece hot-roll drying system disclosed by the invention, the pole piece of a lithium battery can be rapidly dried, and the drying effect is good.

Description

technical field [0001] The invention relates to the technical field of lithium battery drying equipment, in particular to a thermal roller drying system for pole pieces. Background technique [0002] At present, the lithium battery industry at home and abroad has a good development prospect. Lithium-ion batteries have been widely used in portable electrical appliances such as laptop computers, cameras, and mobile communications due to their unique performance advantages. The currently developed high-capacity lithium-ion battery has been tested in electric vehicles and is expected to become one of the main power sources for electric vehicles in the 21st century, and will be more widely used in satellites, aerospace and energy storage. With the shortage of energy and the huge pressure on the world's environmental protection. Lithium batteries are now widely used in the electric vehicle industry, especially the emergence of lithium iron phosphate batteries, which has promoted ...
