High-flatness adjusting mechanism of coating machines

Abstract

The invention discloses a high-flatness adjusting mechanism of coating machines which is provided on a hanging plate of a coating machine. The high-flatness adjusting mechanism comprises a vacuum pre-roller-passing assembly and a roller tensioning mechanism. The vacuum pre-roller-passing assembly is placed under base materials. The roller tensioning mechanism is located above base materials; the roller tensioning mechanism has a symmetrical structure on a horizontal center line. The roller tensioning mechanism comprises 2 fixed plates on left and right, a fixed seat for sliding bars, a sliding bar, a fixed seat, a connection sliding block for linear sliding rails, an installation vertical plate, a top roller base, a bottom roller base, a sliding block cylinder, an actuating motor, a motor fixing base, a coupling, bearings, gears, bearing housings, rubber rollers and steel rollers. Beneficial effects of the invention are that problems caused by too dry pole pieces are solve by the application of the adjusting mechanism. Batteries are more stable because of the battery pole pieces with high consistency. The adjustment accuracy of the flatness of base materials is high, thus the problem of larger COV is solved.

Description

[0001] technical field [0002] The invention relates to the technical field of mechanical equipment, in particular to a coating machine for slurry coating of lithium-ion battery electrode sheet membranes. [0003] Background technique [0004] Coating machine is a machine used to quantitatively coat liquid (or melt) materials such as adhesives, paints or slurries on the surface of materials. It is suitable for shoe materials, electronics industry, sponge, EVA, PE, cloth, etc. Coating operations in the field. In the electronics industry, extrusion coating or roll coating is usually used to coat lithium-ion battery electrode film slurry, among which extrusion coating is a relatively advanced technology, which can be used for coating higher viscosity fluids and can obtain Higher precision coating. The traditional existing coating technology can only coat one side at a time, and needs to finish coating one side, then coat the other side, and cannot coat both sides at the sam...

AI Technical Summary

Problems solved by technology

The traditional existing coating technology usually can only coat one side at a time, and needs to finish coating one side, then coat the other side, and cannot coat both sides at the same time, so not only the production efficiency is not high, but also the loss of equipment and materials is higher; at the same time, Traditional coating equipment does not adjust the flatness of the base material with high accuracy, which will lead to the following problems: too dry pole pieces, too many parking positions lead to a large COV, too many parking positions affect the quality of the starting pole pieces, etc.
