XIAMENBattery Electrode Coating Machine for Battery Manufacturing
SPECIFICATIONS
1. Effective coating width: 330mm.
2. With 3 sections of oven (each section length 1.5 meters), total length 4.5 meters.
3. With automatic gap adjustment function, more easy for adjustment for abroad customers.
4. Perform both continuous and intermittent coating.
This TOB-SY400-3A battery coating machine is a three-roller transfer coating machine, Can perform both continuous and intermittent coating, which is convenient for surface coating of various substrates. Especially applied to the lithium-ion battery industry, the equipment is designed in the spirit of convenience for researchers, while meeting the requirements of coating accuracy and consistency no different from production, with excellent drying effect, ideal for the research and development of lithium-ion batteries, super capacitors, nickel batteries and other secondary batteries.
Features:
* The pushing roller adopts dual servo screw control, which can adjust the finishing coating according to different viscosity slurries.
* Equipped with material connecting platform, partition platform, unwinding tension, and dual rewinding tension. Set up correction for unwinding, drying end, and rewinding.
* Freely switchable to achieve continuous and intermittent coating.
* Substrate tension control, stable tape running, equipped with correction device.
* Hot air oven, double-sided blowing on both sides, high-quality drying effect.
* Three roll transfer coating with a wide coating window.
* Measurement with comma scraper, combined with precision adjustment mechanism, achieves high coating accuracy.
* Using analog signals to control power heating, the heating system has high accuracy and long lifespan.
* PLC control, touch screen operation, convenient and easy to use.
