Improvement and research of the electric drive of the polymer film cutting
machine

Bondar, I.V.

The subject of the study is the electric drive of the spooler of the bobbin-cutting machine. The object of the study is the process of changing the load during the operation of the electric drive of the bobbin-cutting machine, taking into account the requirements for the technological process of cutting, as well as reducing the costs of energy and technical resources.
The purpose of this qualification work is to improve and research the electric drive of the polymer film cutting machine to increase the efficiency of its operation. The study describes the technology of manufacturing packaging polymer film and general analysis of the equipment for its production and cutting, identified shortcomings in its current operation. The drive was modernized, the parameters of the asynchronous motor replacement scheme were determined, its dynamic parameters were calculated, and the operation of the motor in dynamic modes was analyzed.
A functional scheme of an electric drive with a vector control system was developed, mathematical modeling of this electric drive was carried out, as well as a study of the drive for quality and stability. The study proved the unctionality of the modernized electric drive. The work also includes a selection of devices for automatic control and regulation of the process of production of packaging material from polymer film. After more detailed finishing, the modernized machine can be used in the production of packaging polymer film.
