Laboratory Intermittent Three-Roller Precision Coating Equipment for Battery R&D

Introduction

The intermittent laboratory coating machine is a three-roller transfer-type coating system capable of both continuous and intermittent coating. It is designed for surface coating applications on various substrates, with a particular focus on the lithium-ion battery industry. This machine is developed to be user-friendly for researchers while meeting high coating accuracy and consistency requirements similar to production standards. With excellent drying performance, it is an ideal choice for R&D and small-scale trials in lithium-ion batteries, supercapacitors, nickel batteries, and other secondary batteries.

Key Features

· Switchable between continuous and intermittent coating for flexible operation.

· Stable web tension control with an auto-correction system to ensure smooth substrate movement.

· Hot-air drying oven with dual-sided air blowing, providing superior drying performance.

· Three-roller transfer coating system, offering a wide coating window.

· Comma blade metering system with a precision adjustment mechanism for high coating accuracy.

· PLC control with touchscreen operation, making the system easy to use.

· Optional solvent recovery and treatment system for enhanced environmental safety.
