Aluminium foil jumbo roll edging and winding problem and solution

Aluminium foil jumbo roll burrs: There are powdery metal aluminum scraps on the end face of the double-coated aluminium foil jumbo roll, which appear when the aluminium foil jumbo roll is trimmed. The essence is that the two double-coated aluminium foil jumbo rolls are shifted from left to right before rolling or the trimming edges are uneven when they are combined.

cause:

1. The shaft joint is not correct

2. The incoming material is loose

3. Too much Shuanghe oil

4. Edge trimming system problem

At present, it is mainly improved through the following ways:

1. Increase the tension when closing the roll, and cut the edge as wide as possible

2. Improve the shape of incoming material

3. The double-helix oil can be appropriately increased for the pine material on the opposite side

4. Adjust the position of the trimming knife

aluminium foil jumbo roll rolling is also called tower shape: during the process of aluminium foil jumbo roll winding, the edge of the aluminium foil jumbo roll is not neat, and the aluminum coil slides to one side, one end is trumpet-shaped, and the other end is in the shape of a bamboo shoot.

cause:

1. The coiling tension is small, resulting in loose aluminum coil

2. Bad shape

3. The pressure at both ends of the coiling and flattening roller is unbalanced, or there is a problem with the flattening roller itself.

solution:

1. The aluminium foil jumbo roll coiling tension is appropriate

2. Adjust the pressure balance at both ends of the flattening roller

3. It is indeed a problem with the flattening roller, notify the relevant personnel to deal with it
