In the process of slitting processing using the slitting machine, the problem of rewinding failure is sometimes encountered, which is mainly manifested as bumps, uneven tightness, unequal rewinding and other problems in the slitting material during winding. These problems not only affect the processing efficiency, but also the quality of the product. The following is a detailed introduction to the fault problems of the slitting machine winding and their solutions.
1. Varying elasticity
Varying tightness refers to the problem caused by the different tightness of the coil after rewinding. This problem can be caused by excessive bearing clearance or unbalanced bearing wear. The way to solve this problem is to replace the damaged bearing in time or make bearing clearance adjustment to ensure that the bearing works smoothly.
2. Uneven rewinding
Uneven rewinding refers to the problem that the edge of the coil is uneven, the core in the center area is round, and the outer edge is flat. This problem may be caused by factors such as excessive knife clearance, excessive knife error, or the mismatch between the linear speed of the rewinder and the spindle. This can be solved by eliminating cutter clearance, adjusting for cutter errors, or redesigning the rewinder's linear speed to match the spindle.
3. The coil is bumpy
Coil bumps refer to the problem that the coil is bumpy during the rewinding process, resulting in poor roll quality. This problem can be caused by the linear speed of the rewinder not matching the spindle, the unsuitable tension, or damage to the pneumatic components. The solution to this problem is to redesign the linear speed of the rewinder, adjust the tension reasonably or replace the damaged pneumatic components in time.
In summary, the problem of rewinding failure of the slitting machine may bring a lot of trouble to production. Therefore, factory managers should strengthen the maintenance and maintenance of equipment in daily operation, replace damaged parts in time, and avoid failures. In the operation, care should be exercised, and the operation should be strictly in accordance with the operating procedures to ensure the normal operation of the equipment and the quality of the product.
