Implementación de un prototipo mecánico de una pigmentadora para la aplicación de los acabados del cuero

Abstract

The implementation of the mechanical prototype for the leather finish application was made in the Laboratory of tanning of skins of the Animal Science Faculty (ASF) of the ESPOCH using as experimental units four vegetable tanned leathers and four chrome tanned leathers. The results show that the use of the dyeing machine arises from the need to promote the standardization of dry treatment; it is compose by a roller table that allows the advance of the leather while three nozzles spread the painting on the same one that is moved slowly under the above mentioned painting jets, reducing the finishing time, with the advantage of forming a uniform paint curtain. Once installed the mechanical prototype was conducted its validation through testing of different tanning leathers which determined physical resistances that exceeded the requirements of leather quality, and excellent sensory ratings that are indicative that the finishing layers have been properly atomized in the leather total surface. The equipment operates with a 220 V, three-phase supply, the main supply is awarded to the reduction motor, the same one that is closed completely. The equipment efficiency was 85%, high value, considering it was built with local labor and national raw materials, confirming the technological competitiveness that our country has. The cost of the construction of the Dyeing Machine was $ 2700; that compared with international machinery is lower.
