Improvement Study Of The Tension And Alignment Control For The Gravure Machine

Because our country gravure machine development later, initial are imitated foreign products, general machinery and technology level, low speed in 150 m/most below, due to lack of matching accessories, professional production manufacturer of generality, fittings to promote technology level of early slower, most cheap homebred gravure machine equipment. Due to the early homebred gravure machine many problems, in order to adapt to the needs of the development of the enterprise, according to their own will, or to update equipment, or modification of equipment. The unit has two early homebred gravure machine, its design speed and accuracy are relatively low, after years of use, speed and accuracy, relative low quality products, production efficiency is low. Gravure machine control system, the tension control is very important one annulus, control a direct influence on the product quality and production efficiency. Automatic adjustment control is the printer control system is the core and key factors of decision accuracy, determines the qualified products. Through the analysis of the status quo of machine, the volume of structure of the transmission system is improved, and the combination of variable frequency motor inverter control device, the execution instead of magnetic powder clutch/brake, through the operation effect is better, this kind of control mode of features are: reliable operation and mechanical wear small, high control accuracy, simple operation, low malfunction. In automatic control system by hubei, adjustment of automatic control equipment of yichang 135/240 afc system improvement, this system has advantages of patent color mark due, very suitable for transformation equipment, through that improves the accuracy of equipment, reduce scrap adjustment. Through the reform, the equipment production speed and improve production efficiency and lower cost.
