Abstract

This invention discloses a coating tandem rolling system for battery pole plates including: 1, a double-side sealing die extrusion coating machine, 2, a rolling mill for battery pole plates, 3, a continuous horizontal machine to be connected to become a coating, rolling and itemizing continuous operation system for the Li battery active substances by a strain sensor, in which, the sealing coating box is installed in the middle of the double-side sealing die extrusion coating machine, the pole plate collector passes through the sealing die extrusion coating, three drying boxes and a strain sensor then enters into the rolling and itemizing machine to be winded up so as to increase the production efficiency by over two times.

Description

technical field [0001] The invention belongs to the scope of battery pole piece manufacturing equipment, in particular to a battery pole piece coating continuous rolling system. Background technique [0002] Due to the petrochemical energy crisis and environmental pollution, new energy sources and energy storage methods such as nickel metal hydride, lithium ions, lithium polymers, zinc-air fuel cells, and solar cells are developing rapidly. Therefore, the demand for pole piece manufacturing equipment for batteries such as nickel-metal hydride, lithium-ion, zinc-air fuel, aluminum-air fuel, and hydrogen-air fuel is also increasing, especially the demand for battery pole piece coating continuous rolling equipment is more urgent. At present, imported or domestic battery pole piece coating and rolling equipment are all single-machine operations in three stages of coating, rolling, and slitting, and the coating machine is single-sided or double-sided horizontal transfer coating, ...
