Scotch Tape Coating Machine

Scotch Tape Coating Machine

1.Main engine & pump full-automatic tracking system and constant tension control system, no matter ensure the coating stability, improve the material compound roughness.

2.Double position for taking up roller and full automatic not reduce changing roller, greatly improve the equipment operation and produce efficiency.

Fourth, the process requirements: positive and negative electrode coating:

Double-sided total dressing density:
1. The first coating length deviation is ≤ 2 mm, and the coating gap deviation is ≤ 1 mm. 2. The maximum misalignment between the second side and the first side is ≤ 1 mm.
3. The maximum deviation of the thickness of the coated single film is ≤3um, and the maximum deviation of the thickness of the double film is ≤6um. 4. The maximum deviation of the density of the coated single film is ≤ 4%, and the maximum deviation of the density of the double film is ≤ 8%. 5. The maximum error of coating tailing is ≤1mm.
6, the film surface should be flat, can not appear dry cracks, wrinkles, particles, streaks. 7. Coating width = single strip width multiplied by the maximum number of coatable sheets + 5 ~ 10mm.

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.
