Diseño y construcción de un equipo para el termolaminado plástico con control semiautomático para un ancho máximo de 30 cm.

Abstract

The graphical industry in Ecuador has a large variety of products to give a fine Surface finish of printed materials. The dust and wetness are the fundamental reasons for graphical industry to search a proper protection. Thats why they usually to plasticized the printed products. There is the need of adquire the right machines to perform the process of plasticizing smoothly. This proyect has the target to design and manufacture a prototype. The equip is going to plasticize two sides, at the same time, of paper and plastic for sizes until A3. The principle of heat transfer between two rollers heaters is used. It will be like a printing machine. The design will incorporate a electronic system to optimizing the procedure of heat transfer between the paper and the plastic. The chapter one will offer mechanical fundamentals and heat transfer fundamentals of the design of the prototype. And the primal specifications needed for a standard procedure, will be obtained. With this specifications it will proceed to the material selection. The chapter two has the study of the principal machines found in the market. The parameters to be watched are: machine cost, difficulty in construction, selection of manufacturing materials and the maintenance needed. Later, each parameter will be qualified and a comparative chart will help in machine type selection. With the selection of the right machine, the chapter three show the design with all the calculations required. The transmission system, structure, power needed and the electronic panel are going to be selected in the chapter 3. It will proceed, with the respective schematics, to the construction of the prototype. Finally, several field tests are going to be needed to find the right functioning of the prototype and determinate the conclusions and recommendations of the project.
