Description

Technical Field

[0001] This invention relates to the field of online perforation technology for nonwoven fabrics, specifically to an online perforation system for nonwoven fabrics. Background Technology

[0002] Nonwoven fabric, also known as non-woven cloth or non-woven textile, is a type of fabric formed without spinning or weaving. It is made by arranging short or long textile fibers in a directional or random manner to form a web structure, and then reinforcing it using mechanical, thermal, or chemical methods to create a sheet-like material. As a new type of environmentally friendly material, nonwoven fabric plays an increasingly important role in modern society due to its unique properties and wide range of applications. With the continuous advancement of production technology and the expansion of application areas, perforation is a commonly used nonwoven fabric processing technique. Perforation can improve the air permeability, absorbency, and adaptability of nonwoven fabrics.

[0003] Traditional online punching systems for nonwoven fabrics often employ mechanical punching methods, such as using steel nails or blades. This method is not only slow but also difficult to achieve continuous and efficient punching operations. As the production speed of nonwoven fabrics continues to increase, the efficiency bottleneck of traditional punching systems has become increasingly prominent. Traditional punching systems are prone to problems such as uneven punching and hole position deviation during the punching process. These problems not only affect the appearance quality of the nonwoven fabric but may also adversely affect its performance. Furthermore, traditional punching systems typically require a large amount of manpower, including the operation, maintenance, and adjustment of the punching equipment. This not only increases labor costs but may also lead to a decrease in production efficiency. In addition, because traditional punching methods are prone to quality problems, additional rework and inspection costs are required, further increasing production costs. Therefore, a new system is proposed to solve this technical problem. Summary of the Invention

[0050] Safety protection devices: to prevent accidents during the winding process, such as overload, overheating or mechanical failure. Safety protection devices may include emergency stop buttons, overload protectors and temperature sensors.

[0051] Preferably, the control system module is the core part of the entire system, responsible for coordinating the work of each module. By adopting advanced control algorithms and detection equipment, it achieves precise control of the drilling process. By providing a user-friendly human-machine interface and fault diagnosis functions, it reduces the difficulty of operation and workload.
