In the process of using the slitting machine for slitting processing, sometimes the problem of rewinding failure is encountered, which is mainly manifested in the problems of bumps, inconsistent tightness, and uneven rewinding of the slitted material when coiling. These problems not only affect the efficiency of processing, but also the quality of the product. The following is a detailed introduction to the fault problems existing in the slitter rewinding and its solutions.
1. The tightness is different
Inconsistent tightness refers to the problem caused by the different tightness of the rewound coil. This problem can be caused by excessive bearing clearance or unbalanced bearing wear. The solution to this problem is to replace the damaged bearing in time or adjust the bearing clearance to ensure that the bearing works smoothly.
2. Rewinding unevenly
Unwinding refers to the uneven edge of the coil, the core in the center area is round, and the outer edge is flat. This problem may be caused by factors such as too large knife clearance, too large knife error, or a mismatch between the linear speed of the rewinding wheel and the spindle. The solution to this problem is to eliminate the knife gap, adjust the knife error, or redesign the linear speed of the rewinding wheel to match the spindle.
3. Coil bumps
Web bump refers to the problem of web bumps during the rewinding process, resulting in poor web quality. This problem can be caused by a mismatch between the linear velocity of the rewinding wheel and the spindle, an inappropriate tension or a damaged pneumatic component. The solution to this problem is to redesign the linear speed of the rewinding wheel, adjust the tension reasonably or replace the damaged pneumatic components in time.
To sum up, the problem of rewinding failure of the slitting machine may bring a lot of trouble to production. Therefore, plant managers should strengthen the maintenance and maintenance of equipment in daily operations, replace damaged parts in time, and avoid failures. In the operation, we should be cautious and strictly follow the operating procedures to ensure the normal operation of the equipment and the quality of the product.
The tension of the slitting machine is an important factor in controlling the slitting results of the product, which is very helpful for the running speed, uniformity and stability, so special attenti
