Product Introduction
Product Introduction
This Battery coating machine is used in the coating process of positive and negative electrode sheets for lithium batteries. It employs a three-roller transfer principle design, consisting of a metering doctor blade, coating roller, and rubber roller, enabling both continuous and intermittent coating processes. This equipment is also suitable for coating processes with other types of slurries and substrates. It is ideal for laboratory or sample production lines for process exploration of products.
Product Features
1. A series of products, with selectable coating methods, drying methods, and functional modules to meet specific needs.
2. Wide coating window, adaptable to various coating scenarios, especially suitable for early-stage R&D and small-batch production.
3. Capable of continuous and intermittent coating with high coating precision.
4. Substrate tension control, allowing for low-tension tape feeding and stable tape feeding.
5. PLC control and HMI operation, convenient and easy to use.
6. Compact size and easy-to-operate design.
7. Standard hot air drying oven with single-sided air outlet for excellent drying effect.
8. Infrared drying oven optional.
9. UV curing optional.
10. Flattening function optional.
11. Corona treatment function optional.
12. Static electricity elimination function optional.
Equipment Overview
1. This Battery coating machine controls the winding and unwinding speed by varying the position of the tension rollers, using the rotational linear speed of the rubber rollers as the primary drive speed to control the substrate feed.
2. This equipment controls the coating thickness by adjusting the distance between the metering doctor blade and the coating roller. The coating layer is completely transferred to the substrate surface via the reverse rotation between the coating roller and the back roller. The coating thickness on the substrate surface is further controlled by adjusting the speed ratio between the coating roller and the back roller.
3. After single-sided coating, a reverse single-sided coating can be applied to the coated roll to achieve double-sided coating.
4. Intermittent and continuous coating can be achieved by controlling the forward and backward movement of the rubber rollers.
5. The drying chamber uses electric heating or infrared radiation to heat and dry the front side of the substrate. Solvent is removed through exhaust ventilation.

Product Advantages
1. Feeding Section: Features a stable slurry supply, feeding, and control system, facilitating high-precision continuous production.
2. Heating Section: Incorporates a hot air circulation system capable of expelling solvents released during the initial evaporation phase; exhaust gases are prevented from re-entering the circulation loop, thereby ensuring operational safety.
3. Curing Section: Comprises a tunnel-style curing chamber paired with a high-temperature-resistant Teflon conveyor belt. Customers may choose from various heating options-including stainless steel electric heating tubes or far-infrared quartz heating tubes-and benefit from a multi-segment modular design tailored to meet diverse operational requirements. The section also features superior thermal insulation engineering, effectively satisfying a wide range of specific process demands.
4. Cutting Section: This Battery coating machine is equipped with a professionally designed, multi-functional slitting machine capable of performing a comprehensive range of operations-from peeling, laminating, and edge trimming to final slitting or rewinding. This integrated design optimizes floor space utilization, reduces labor costs, and minimizes yield losses typically associated with manual handling and intermediate transfers.
5. Control System: Features a fully digitized control system wherein all adjustable parameters-including tension, gap settings, speed, and production count-are displayed digitally. This facilitates the establishment of standardized operating procedures (SOPs) and reduces operational reliance on individual operator experience.
