Kunshan Youyuan Sheng Machinery Co., Ltd. specializes in manufacturing and selling various types of paper cutting machines, including slitting machines, rewinding machines, laminating machines, and die-cutting machines. One common issue that our customers have reported is that the paper tray on the right side of the slitting machine tends to bulge out after some use. Here are some possible causes and solutions.

1. Uneven winding tension: If the tension of the paper roll is not evenly distributed, it can cause the paper to bunch up on one side. This can happen if the roll is not properly aligned or if the tension control system is not functioning correctly. To solve this problem, operators should carefully adjust the roll position and check the tension control system regularly.

2. Blade wear: Over time, the slitting blades can become dull or damaged, which can cause the paper to pull to one side. If this is the case, operators should replace the blades as soon as possible to maintain a clean and consistent cut.

3. Conveyor belt misalignment: The conveyor belt that carries the paper through the machine can become misaligned over time, which can also cause the paper to shift to one side. Operators should check the alignment of the belt regularly and adjust it if necessary.

4. Outdated software: If the machine is running on outdated software, it can cause inaccurate cuts and uneven tension that may lead to paper bunching. Updating the software can solve this issue.

In conclusion, the bulging of the paper tray on the right side of a slitting machine can be caused by various factors, including uneven winding tension, blade wear, conveyor belt misalignment, and outdated software. Proper maintenance and regular checks can help prevent this problem and ensure a smooth and efficient production process. At Kunshan Youyuan Sheng Machinery Co., Ltd., we strive to provide our customers with high-quality machines and excellent after-sales service to meet their needs.
