Abstract


DaQing petrifaction acrylic fiber factory has five product lines which were brought in 1990s from abroad. The lines had ran for many years and because rolling equipments’malfunction, they were always hanging-up. Movable Packing machine is a special use mechantronics equipment, which is manufactured to reduce tows waste when production line is break. A simple operating, high reliability Movable Packing machine used in acrylic fiber product lines is designed in this paper by the means of digital and optimum design methods.The quality of Packing acrylic fiber is an important problem which must be considered in the process of designing Movable Packing machine, it’s also very important in packing procedure of acrylic fiber product lines. The parameters of electromotor must be preset reasonably, and the parameters used in product lines are got by test. To understand the moving state of tows, modeling method which based on tabby fabric physical characteristic is used. And tows is divided into clusters in modeling, a new physical modeling is built based on the moving tows’characteristic, and the paper analyzes the modeling process. And research in the field should be enhanced, this paper is written with the hope that which can be favorable for relevant research in this field.After studied the functions of acrylic fiber packing equipment and compared several methods, final scheme is choose. And the working process of packing machine is designed according to the system’s functions. Then the system is divided into three parts, which are operating part, sensing and detecting part and electrical control part.In order to produce high reliability Movable Packing machine, traditional and digital design methods are used in this paper and the important parts of the structure is designed optimally. Firstly, problems of tows stacked, drawing wheel stuck and tows wrapping of the equipment is studied, and the improved scheme is analyzed using ADAMS software. Secondly, the paper designs the driving components using digital method, and low-cost scheme is achieved. Thirdly, the main frame has been designed optimally by the means of statics and modal analysis in ANSYS software. After all, the precisely numeral model of the Movable Packing machine is completed by PRO/E.The electrical control system for Movable Packing machine is designed on the basis of the completed mechanical system. The electrical control system is designed under the controlling parameters. And this system has some features: highly automatic, low cost, simple and reasonable strategy, ease operating. The paper uses more general, high reliability electrical components which are ease of use and maintenance. The control strategy of the system is analyzed. To control the electromotor for machine moving, the PLC-based program control is achieved with the completed corresponding control strategies. Finally, the whole electrical control system is completed.
