Afegir etiqueta | Sumari: | The present technological proposal consisted in the repowering of a polyethylene hose manufacturing process, specifically in the extruder machine and tensioning machine achieving a quality product, the main problems were that in the plastic melting area of the extruder machine had an unstable and unsafe control system of LPG gas and there was no electric board, On the other hand, the tensioning machine had no speed control and its electrical panel was poorly positioned because it was exposed to falling water, therefore, the electrical control, protection and power drawings were made using the respective IEC electrical symbology provided by the Cade Simu software for subsequent selection, acquisition and implementation of the elements and equipment that were selected, an On/Off control was made for the plastic melting system using 4 J-type thermocouples, 4 industrial burners and 4 solenoid valves that allow the flow of LPG gas which is controlled by means of the Logo V8 automaton, additionally in the feeding hopper the capacitive sensor that indicates the low level of raw material was kept, for the tensioning machine a Sinamics V20 frequency variator was included in the control board and it was found that at a speed of 40 RPM the 2 mm of thickness that the hose needs is obtained, The rotary encoder sensor was kept in this machine determining the 100 meters of hose that are commercially used, as results highlight that a daily decrease of 66.67% of material waste was obtained, in addition it is necessary to preheat the heating zone of the extruder machine for 20 minutes until it reaches and maintains the temperature of 200 °C and having a capacity of 50 kg/h of the extruder machine can manufacture 20 rolls /day of 1 inch hose. |
