In the sanitary napkin manufacturing industry, "speed" and "efficiency" are the core indicators measuring the competitiveness of production lines, directly determining the production scale and cost control capabilities of downstream brands. Currently, the speed of mainstream fully automated production lines in the industry generally stays between 800-1000 pads per minute, with an energy consumption of approximately 0.6 kWh per unit product. However, leading enterprises have achieved breakthroughs in key indicators through technological innovation —— taking a leading equipment manufacturer as an example, its latest generation of production lines not only increases the speed to 1200 pads per minute but also reduces the energy consumption per unit product to 0.25 kWh, achieving a 30% reduction in energy consumption and redefining the industry standard for high-efficiency production.
Speed Breakthrough: The "Stability-Speed Balance" Behind 1200 Pads per Minute
Increasing the speed of production lines is by no means a simple "accelerated operation"; it requires finding a precise balance between "high speed" and "stability". Industry data shows that when the speed of production lines exceeds 1000 pads per minute, problems such as raw material deviation, incomplete edge sealing, and rising defect rates of finished products are prone to occur. Although some enterprises can temporarily reach 1100 pads per minute, the defect rate will soar from 0.3% to over 1.5%, which instead increases production costs.
The core of achieving stable operation at 1200 pads per minute lies in the upgrading and iteration of servo control systems. The new-generation servo system adopts dual-axis synchronous drive technology, controlling the mechanical transmission error within ±0.05 mm. Combined with a real-time visual inspection module (with an inspection frequency of 500 times per second), it can instantly detect issues such as raw material deviation and absorbent core misalignment, and dynamically adjust through servo motors to ensure the processing accuracy of each product. After a leading sanitary napkin brand introduced this production line, its daily output increased by 25%, while the defect rate remained stable below 0.2%, and the annual additional income of a single production line exceeded 8 million yuan.
In addition, the "modular design" of the production line also provides support for high-speed operation. The equipment divides processes such as unwinding, forming, edge sealing, and cutting into independent modules. All modules realize data interconnection through industrial Ethernet. When a slight abnormality occurs in a certain module, the system can automatically adjust the operating parameters of adjacent modules to avoid the shutdown of the entire production line. Compared with traditional integrated production lines, the modular design reduces the equipment failure rate by 40%, effectively ensuring the continuity of high-speed production.
30% Reduction in Energy Consumption: The Technical Transformation Path of Green Production Lines
Driven by both the "dual carbon" policy and cost pressures, "high efficiency" no longer only refers to "high speed" but also includes "low energy consumption". Industry research shows that energy costs account for 12%-15% of the total production cost of sanitary napkins, so reducing energy consumption has become a crucial breakthrough for enterprises to cut costs and improve efficiency. To achieve a 30% reduction in energy consumption per unit product, efforts must be made simultaneously in two aspects: "energy-saving of core components" and "process optimization".
From the perspective of core components, the energy efficiency upgrade of servo motors is the key. The new-generation production lines adopt permanent magnet synchronous servo motors, whose energy efficiency level reaches the IE4 standard, saving 15%-20% more energy than traditional asynchronous motors. At the same time, they are equipped with intelligent energy management systems that can dynamically adjust the output power of motors according to production load —— when the production line is in a low-load state such as "small-batch specification switching" or "raw material supply", the system automatically reduces the motor power to avoid energy waste. According to the calculation data of a factory, the upgrade of servo motors alone can reduce the energy consumption per unit product by 18%.
Process optimization further amplifies the energy-saving effect. By changing the traditional "hot air drying" process to "heat pump cycle drying", the waste heat recovery system is used to increase the heat energy utilization rate of the drying process from 55% to 85%. At the same time, the forming process of the absorbent core is optimized to reduce the number of raw material compressions, reducing the energy consumption of the hydraulic system by 22%. Through the superposition of multiple technologies, the energy consumption per unit product is finally reduced from 0.8 kWh per pad to 0.56 kWh per pad. Based on the daily output of 2 million pads of a single production line, the annual electricity cost can be saved by more than 1.2 million yuan.
Conclusion: The Essence of High-Efficiency Production is "Precise Matching of Technology to Demand"
Whether it is the speed breakthrough of 1200 pads per minute or the 30% reduction in energy consumption, the essence is the precise matching between production line technology and the needs of downstream brands. Currently, leading sanitary napkin brands not only need high speed to meet the surging consumer demand in the market but also need low energy consumption to control costs and comply with environmental policies. The breakthrough in the indicators of the new-generation production lines exactly solves this core pain point.
In the future, with the integration of material technology (such as thinner and more lightweight biodegradable bottom films) and intelligent algorithms (such as AI predictive maintenance), sanitary napkin production lines may achieve a new goal of "1500 pads per minute + a further 15% reduction in energy consumption". For equipment manufacturers, continuous data-driven and customer demand-oriented technological innovation is the key to maintaining competitiveness in the industry.
