XIAMENLaboratory Roll to Roll Transfer Coating Machine For Battery Electrode
SPECIFICATIONS
The TOB-SY300-2J laboratory transfer coating machine is a three-roller transfer coating machine that allows for continuous and intermittent coating and is convenient for applications in surface coating processes on a variety of substrates. Particularly suitable for the lithium-ion battery industry, the machine is designed for the convenience of the researcher, while meeting the requirements for coating accuracy and consistency without any variation from production, and has excellent drying results, making it ideal for R&D and small trials on lithium-ion batteries, supercapacitor, nickel batteries and other secondary batteries.
Dimension：L 1800*W 1300*H 1200mm, Weight about 1.2T.
Features:
- Plasma cleaning function optional.
- Can switch freely to achieve continuous and intermittent coating.
- Substrate tension control, transport stability, configuration correction device.
- Hot air oven, the upper and lower double-sided blowing, high-quality drying effect.
- Three-roll transfer coating, wider coating window.
- Comma scraper measurement, with precision adjustment agencies, access to high-precision coating.
- Power generation with analogue signal control, high accuracy ±0.3°C of the heating system and long life.
- PLC control，Touch screen operation, easy to use.
- Optional solvent recovery device.
