The rewinder is used for the rewinding of the coil material after stamping automation. The commonly used hydraulic uncoiler, light type uncoiler, and double-head uncoiler are also often used for rewinding.

The main reasons for the uneven winding of the uncoiler are as follows:
1. The center line of the uncoiler and the press punching machine are not on the same line, resulting in uneven rewinding.
Solution: When the winding of the uncoiler is uneven, first check whether the center line of the uncoiler is consistent with that of the press punching machine. If it is inconsistent, it needs to be adjusted immediately.

2. The stopper limit device of the uncoiler is not reliably limited, resulting in uneven rewinding.
Solution: Adjust the stopper limit device [usually the position of the stopper A-type iron], so that it can effectively limit the winding material.2. The stopper limit device of the uncoiler is not reliably limited, resulting in uneven rewinding.
Solution: Adjust the stopper limit device [usually the position of the stopper A-type iron], so that it can effectively limit the winding material.

3. When the material is not adjusted properly, the winding work starts, resulting in uneven winding.
Solution: When the uncoiler is used for winding, it should be ensured that the material is manually wound for 5-6 turns to ensure that the material is wound neatly.

4. When the uncoiler is used for winding, the thickness of the material strip is uneven, one side is thick and the other is thin, and the winding speed is different
Solution:
1. If the rewinding is useless material, the requirements for rewinding are usually not high, and the rewinding speed can be adjusted appropriately to ensure that the rewinding is tightened.
2. If the rewinding is the required material, a tensioning device needs to be installed (it is recommended to use an uncoiler with tensioning function). The uncoiler with tensioning function can maintain the tension continuously, which ensures that the uneven thickness of the coil can be collected neatly.

The reasons and solutions for the uneven winding of the uncoiler machine are mainly the four points mentioned above. Of course, you can also contact Henli directly, and we will provide you with professional answers and services.
