Li-Battery Anode Paste Slot Die Single/Double Surface Coater for Lithium Battery Pole Piece Production

Product Description

Li-Battery Anode Paste Slot Die Single/Double Surface Coater for lithium battery pole piece production
1. Feature and advantage:
1.Enabling continuous coating, gap coating, stripe coating, the rectangle shaped coating;
2.Coater can speed up to 25m/min;
3.The dry thickness accuracy of the coater can be controlled within ±1.0µm/single surface;
4.Oven using floating structure, evenly air flow, high drying efficiency;
5.Heating modes including electric heating, steam heating, oil heating, gas heating etc.
Temperature control precision can reach ± 1 ºC , each section of the cabinet have ex-proof setting. It is safe and reliable, energy saving and environmental protection
6.The machine can be equipped with online areal density or thickness tester, real-time monitoring the changes of areal density or thickness during coating process.
The feeding system can be closed-loop adjusted automatically through PLC controlsystem to ensure consistency of the coating layer. All data can be recorded;
7.The coater length plus the length of the blank can be controlled within the precision ± 1mm,positive and negative face counterpoint error ± 0.5mm.Provided with a rewind function,fault alarm and fault display function ,operation interlock,emergency stop functionand the communication function.
