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.
In the coating process, the coating gap is poor and the pole piece wrinkles are analyzed:
3. The front and back are not aligned
(1) Operational aspect: the first side gap is consistent. The operating parameters are not adjusted well. The light eye is blocked. The unwinding pinch roller forgets the clip.
(2) Equipment: The tension behind the second side is large. The front tension is small.
4 When the middle is turned on, the white space becomes smaller, and the back 3-4 pieces are inaccurate.
Equipment: The tension is not allowed at the beginning of the start. The first side has no memory function. The foil strip slides forward 2-3mm when starting. The tension starts first when starting. The back roller does not turn. The coating head has no pinch roller or is not clamped.
5. The last piece is in a parallel trailing tail
Operation: coating the back roller spacing (the first side is tailed, the second side is not trailing); the back roller is pulled slowly when the machine is stopped 6. The head thickness is thin or the head is thin and thick. Operation: The head and tail parameters are not adjusted well 7 There is no effect on the action
(1) Material: The foil is tight on both sides
(2) Equipment: the foil tension is small and the moment leaves the back roller.
8. Double-sided large piece of whitening phenomenon: the light eye is not sensed. The first side gap is abnormal. The light eye is covered.
Second, the length of the coating section changes, the spacing is unstable:
6. When the back roller and the coating roller are in contact with each other, the gap between the two ends is inconsistent and the pole piece is wrinkled. Regardless of whether the first side or the second side is applied, the gap should be carefully adjusted. First, the gap is appropriately enlarged, and then slowly reduced. At the same time, observe the dial scale of the coating roller just touching the foil strip, and then Reduce the gap by 0.03mm.
7. When the correction system is abnormal, the pole piece will be wrinkled. Check the three correction systems before and after the inspection, whether it is in the automatic state. If the lengths of the foil strips are inconsistent, that is, when the file is bent too much, the pole pieces will be wrinkled. Exceeding the correcting ability, the foil has to be replaced. 8. When the pole piece tension is too large, the pole piece is wrinkled. Check that the tension setting is reasonable. Then check each drive roller. The rotation of the take-up roll is flexible. Handle inflexible rollers in time.
9. When the back roller is in the inconsistent stroke, the pole piece is wrinkled. It is necessary for the mechanic to check. Confirm and adjust. After the back roller and the coating roller are pulled apart, the gap between the two sides is 1mm (see the dial indicator), and the test is started. When the tail is qualified, lock the nut.
10. The surface of the rubber roller on the back roller will undergo periodic elastic deformation during re-use. When a certain degree of deformation remains, wrinkles will occur. At this time, new products must be replaced.
11. The cause of looseness of a certain roller fastening screw causes the parallel state of each roller to be destroyed, and wrinkles may occur at this time. As long as it is found in time to adjust and tighten in time.
