It is suitable for manufacturing hot stamping film, laser film, gold and silver paperboard which need coating and laminating.
Coating Machine - Process flow
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.
Coating Machine - Head inspection items:
1, foil tape inspection, must meet the process standards.
2, the pole piece has a leaky foil, and the shutdown is clean.
3, there are scratches in several consecutive sections, and clean in time.
4. There are scratches on the guide roller, and the machine is wiped clean.
5, the gap is not parallel for several consecutive sections, stop adjustment.
6, tracking, gap, coating length is not accurate, stop adjustment.
7. The foil strip runs around and checks whether the correction is in the servo state.
8. The edge of the pole piece is too wide and has no edge, and the baffle plate is adjusted.
9. Always ensure that the hopper's slurry is full.
10. After the operation is completed, thoroughly clean the machine head.
