Electric car lithium battery pole piece dryer adopting V-shaped tensioning mode

Abstract

The invention relates to an electric car lithium battery pole piece dryer adopting a V-shaped tensioning mode. The electric car lithium battery pole piece dryer comprises a bottom plate and a pole piece, wherein a drying box is installed at the left end of the bottom plate, the drying box is used for drying slurry uniformly covering the pole piece, both the left end and the right end of the drying box are respectively provided with an opening structure, the pole piece can enter from the left opening structure of the drying box and is output from the right opening structure of the drying box, a corrugated heating pipe is arranged on the top inner wall of the drying box, and the heating pipe heats the slurry on the pole piece entering the drying box, so that the drying speed of the slurry is increased, and the drying effect is good. The electric lithium battery pole piece dryer can realize a high-efficiency drying function and an automatic tension adjusting function of the pole piece in a coating process and has the advantages of good tensioning effect, good conveying stability, short drying time, good drying effect, high working efficiency and the like.
