Pole-piece hot-roll drying system

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.
