In modern life, napkins (napkins) have become an indispensable item in homes, restaurants, and public spaces. With growing market demand, companies are placing higher demands on production efficiency and product quality. Traditional napkin production equipment often struggles to meet the efficiency and precision demands of modern production, making intelligent upgrades an inevitable trend in the industry. In particular, the introduction of PLC intelligent control systems has significantly improved the accuracy, automation, and stability of napkin tissue machines.

PLCs (Programmable Logic Controllers), as core control devices in industrial automation, offer high stability, fast response, and strong programmability. In napkin paper machine production, PLCs primarily perform the following key functions:

• Precisely control the production process

  In napkin tissue machines, paper feeding, folding, embossing, and cutting require highly synchronized operations. By monitoring the position and speed of each actuator in real time, the PLC enables precise control of the production line, ensuring consistent paper size and neat folds, and avoiding product quality fluctuations caused by manual errors.

• Automated Production Parameter Adjustment

  Different napkin sizes require different equipment parameters, such as folding method, paper thickness, and cutting length. The PLC system automatically adjusts the equipment's operating status based on the set production parameters, enabling a single machine to serve multiple purposes, improving production flexibility and reducing manual intervention.

• Data Collection and Real-Time Monitoring

  The PLC collects real-time production data, including production speed, paper tension, and folding accuracy, and displays it to the operator through the human-machine interface (HMI). This not only allows operators to monitor production status at all times but also provides data support for equipment maintenance and production optimization.

• Fault Diagnosis and Protection

  High-speed operation can lead to problems such as paper jams, motor overloads, or folding deviations. The PLC system can promptly detect abnormal signals, automatically stop the equipment, and display fault information, avoiding production losses and equipment damage, and improving production safety.

The introduction of a PLC intelligent control system has significantly improved the production accuracy of the Napkin Tissue Paper Machine. By precisely controlling paper tension and folding rhythm, product dimensional tolerances can be controlled to within millimeters, and the paper texture and embossing pattern are more uniform. Furthermore, the PLC system works in conjunction with servo motors, sensors, and pneumatic actuators to achieve high-precision folding, cutting, and stacking, enhancing the aesthetics and user experience of the final product.
