Actualización del sistema electrónico y diseño del sistema de bobinado de una máquina de pruebas didácticas para desarrollar los procesos de extrusión, halado y bobinado para polietileno.

Abstract

The University Antonio Nariño, South headquarters, has a materials laboratory with various types of equipment to carry out practices in some of the subjects of technological and engineering careers. Among this equipment is a polyethylene extrusion machine which was useful a few years ago to teach extrusion and pulling processes. This work consists of updating the electronic system of an extruder machine in the FIMEB laboratories of the Antonio Nariño university, this update consisted of the implementation of a frequency variator for the extrusion system driven by a 1.2 HP gear motor, Additionally, it was found that as an improvement for the machine, digital temperature controls should be implemented to increase the reliability in the resistance zones, seeking to avoid damage to the extruded product due to faults in the process temperature. In the same way, in the document, you can also see the methodology that was planned to put the extrusion module into operation, which unfortunately could not be concluded. On the other hand, in order to implement an additional process to those that were developed in the extruder, the design of a winding module was carried out in order to be able to implement a system that can help to visualize this manufacturing process. Finally, taking into account the design of the winding module, a redesign of the refrigeration system of the machine was carried out.
