Coating, washing and air-drying system of conducting film

Abstract

The invention relates to a coating, washing and air-drying system of a conducting film. The system is characterized by comprising an unwinding roll, a first guide roll, a coating pool, an anilox roll, a first press roll, a second guide roll, a third guide roll, a drying device, a fourth guide roll, a fifth guide roll, a washing pool, a hot air device, a sixth guide roll, a cooling roll and a winding roll, wherein the unwinding roll, the first guide roll, the anilox roll, the first press roll, the second guide roll, the third guide roll, the drying device, the fourth guide roll, the fifth guide roll, the hot air device, the sixth guide roll, the cooling roll and the winding roll are arranged in sequence; and when the system is used, a film on the unwinding roll passes through a space between the top end of the anilox roll and the first press roll after passing through the first guide roll and the bottom end of the anilox roll and is wound on the winding roll after passing through the second guide roll, the third guide roll, the drying device, the fourth guide roll, the fifth guide roll, the hot air device, the sixth guide roll and the cooling roll in sequence. The system has the characteristics of simple structure and low production cost.

Description

technical field [0001] The invention relates to a system for coating, washing and air-drying a conductive film. The conductive film produced by the system can be used for touch screens and the like. Background technique [0002] The existing conductive film usually adopts evaporation process or magnetron sputtering process. The evaporation process is to evaporate indium oxide onto the film (PET film). The magnetron sputtering process is to sputter a transparent indium tin oxide (ITO) conductive film coating on a transparent organic film (PET film) material. The deficiencies of the existing technology: 1. High energy consumption and high cost; 2. The surface conductivity of the film is uneven; 3. The transparency is low. Contents of the invention [0003] The purpose of the present invention is to provide a conductive film coating, washing and air-drying system, which has the characteristics of simple structure and low production cost. [0004] In order to achieve the ab...
