1. It is provided with anilox roller plus blade for coating mode, and also provided with many selection opportunities of anilox roller with various coating amount.
2. It is provided with separate five-section type constant temperature drying system using infrared stainless steel heating tube plus beating wind, as wellas adjustable interior circulation air draining and suction devices. It is advantageous in strong wind-exit and wind entrance, helping drying thoroughly.
Coating Machine - Process flow
Fifth, the common problems of coating and treatment methods:
1. The unwinding position of the coating head must be fixed, and the tension adjustment is appropriate. Otherwise, the foil will be wrinkled and dark.
2. The correction of the anti-rolling position of the machine head is always set in the automatic state, otherwise the foil will be deflected and the coating will be inconsistent.
3. The machine head slurry is guaranteed to be full, otherwise the pole piece density is not uniform.
4. Adjust the baffle plate as required to ensure that the edge of the pole piece is too wide or too narrow.
5, pay attention to the scratches on the pole piece, and timely use the plug gauge to deal with, or stop the machine.
Coating Machine - matters needing attention
1. The maximum temperature of the positive electrode coating should not exceed 125 oC on one side. The single surface is not easy to dry. The non-stick roller is the standard. The reverse speed is slow and thoroughly dried.
2. The temperature of the single side of the negative electrode should not exceed 105 oC, and the temperature of double coating should not exceed 110oC.
3. The coated pole piece must be completely baked. If it does not dry or has the phenomenon of stripping, the temperature of the temperature zone can be properly adjusted, the temperature can be lowered, the pole piece can be stripped, the temperature can be lowered, and the temperature can be raised.
4. The density is adjusted by adjusting the screw.
5, the thickness is adjusted by adjusting the screw, so that the two sides reach a consistent speech.
6. Adjust the speed and temperature to achieve the best coating.
