Magnetic transport units of tentering and setting range

Considering that the transport units of the traditional tentering and setting range have such drawbacks as low precision,serious contact wear,and poor operational stability due to the adoption of contact auxiliary guide rail,a novel magnetic transport unit for the tentering and setting range was proposed.Its structure and operational principle were introduced.The working process and stress status of the magnetic suspension vertical supporting system and horizontal guide system were analyzed.The horizontal guide system is composed of the linear and arc horizontal guide parts.Because the horizontal guide system has unique suspension air gap and operation mode,it is more complex than the vertical supporting system.The preliminary test indicated that this transport unit has the advantages of high precision,strong anti-interference ability,low energy consumption and so on as compared with the conventional transport unit of the tentering and setting range,thus meeting the development requirement of precision and high-speed in the fields of the modern textile machinery.
