Abstract

The invention discloses an extrusion glue leveling device of a coating machine. The extrusion glue leveling device comprises a power transmission unit, a pressure adjustment unit and an extrusion glue leveling roller, wherein the extrusion glue leveling roller is arranged on a swing arm, and is fitted to the surface of a base material coated with a material in a pressing manner under the action of the pressure adjustment unit; and the extrusion glue leveling roller rotates along a direction opposite to the moving direction of the base material under the driving of the power transmission unit. According to the extrusion glue leveling device of the coating machine, the pressure-adjustable glue leveling roller is adopted to carry out extrusion for glue leveling along the opposite direction after glue is applied, so that the contact area between material particles and a substrate is further enlarged, the adhesion force is enhanced, and the conductivity characteristic of a finished carbon-coated metal foil product is improved.

Description

technical field [0001] The invention belongs to the technical field of power batteries / supercapacitors, and in particular relates to a pole piece double-sided positioning coating machine, in particular to an extrusion and glue leveling device used for the coating machine. Background technique [0002] Power batteries and supercapacitors are widely used in the field of new energy technology. In power batteries and supercapacitors, the pole piece of the electrode is a key component. Coating machines are usually required to evenly coat functional materials on metal foil (copper foil or aluminum foil) On the surface. The principle of a common coating machine is similar to a gravure printing machine. The rolled substrate is conveyed to the coating printing area through the transmission mechanism, and the functional material is coated on the designated position on the surface of the substrate, and then dried, wound, etc., used in the production of subsequent products. Among them...
