In recent years, the level of mechatronics in textile machinery has continued to improve, and AC variable frequency speed regulation has become the mainstream in the industry. New textile machinery is generally equipped with variable frequency speed regulation devices. As efficient and precision weaving equipment, high-speed braiding machines are classified into spindle type and turntable type according to their movement forms, and into vertical and horizontal types according to their working states. This article will introduce the practical application of FRECON FR150A series inverters in vertical high-speed ribbon looms.
The vertical high-speed ribbon loom is mainly composed of a frame, spindle assembly, turntable traction mechanism, frequency conversion drive system, tension control device, and electronic control system. The spindle is responsible for yarn delivery and weaving formation, the traction mechanism stably drives the ribbon forward, and the frequency conversion system precisely controls the rotation speed. The whole machine is equipped with tension adjustment, thread breakage detection, and auxiliary transmission components, featuring a compact structure and coordinated operation, which can realize high-speed, stable, and uniform continuous production of ribbons.
When the vertical high-speed ribbon loom is in operation, multiple groups of yarns are fed out in an orderly manner from the spindles. Driven by frequency conversion, the spindles rotate and interweave at high speed according to the set trajectory to form the ribbon base. The traction mechanism conveys the ribbon forward at a stable speed, while the tension control system maintains uniform yarn tension to avoid slackening or breaking. The electronic control system adjusts the rotation speed and weaving density in real time, and cooperates with the automatic shutdown protection in case of thread breakage, thus realizing continuous, high-speed and precise automatic ribbon production.
This equipment is mainly used for the production of round knitted belts such as shoelaces. Its transmission system is equipped with FR150A series Inverter from FRECON , which drive the dual discs to operate at high speed and stably to complete the weaving process. The equipment has forward rotation, reverse rotation and inching control functions, which can meet the needs of debugging and production. At the same time, it integrates safety functions such as broken thread detection and overload protection. It can promptly identify abnormalities during operation and stop the machine for protection, effectively improving production continuity and equipment safety, making the weaving of knitted belts more efficient and reliable.
After the high-speed braiding machine is equipped with FRECON FR150A series inverters, the overall operation effect of the machine has been significantly improved. The equipment has sufficient low-frequency torque, stable operation, reduced noise, and significantly improved production efficiency.
Inverter realizes stepless speed regulation, with flexible and precise speed control. At the same time, it has multiple protections such as overload, overcurrent, overvoltage, and undervoltage, making the operation safer and more reliable. This solution also reduces the equipment design cost, achieves energy saving and consumption reduction, and provides efficient, stable, and economical operation guarantee for webbing production.
