Description

TECHNICAL FIELD

[0001] The utility model relates to the field of film production equipment technology, more specifically, especially relates to a self-cleaning film washing tank's film punching machine. BACKGROUND

[0002] Through continuous development research, the technology of film structure touch screen is mature day by day. The manufacturing process of film structure touch screen is silk screen printing, simple and fast, thinner, and lower cost. At present, the market share of film structure touch screen is high.

[0003] The conventional film is drawn by a light plotter, and the film product is obtained after developing, fixing, washing and air drying in the punching machine. The film is composed of a protective film, an emulsion layer, a combination film, a base and an anti-halo layer, and the main components are silver salt photosensitive substances, gelatin and pigments. Under the action of light, silver salt can reduce silver core center, but it is not soluble in water, so it can be suspended by gelatin and coated on the base. The emulsion contains pigments for sensitization. The exposed film is then developed in the punching machine, so that the front and back of the film are the same color. Then it is put into the fixing tank to dissolve the silver salt that has not been reduced to silver, and the required pattern is obtained. Then the water washing tank is used to wash off the chemical drugs such as sodium thiosulfate adhered to the film, and finally the film product is obtained by air drying.

[0004] Since the punching machine uses only treated pure water in the washing process, there are no metal ions and it is neutral, so there will be no impurities or dirt in the washing tank. However, the developing solution is alkaline and the fixing solution is acidic. During the film punching process, the metal ions in the developing tank and the acidic solution in the fixing tank will move to the washing tank through the film, making the washing tank acidic and containing a large amount of metal ions. The metal ions will form ion aggregates, i.e. inorganic mineral colloids, under acidic conditions for a long time. These colloids float on the water surface and are adsorbed on the transmission roller and the gap. During the film production, due to the flow of liquid in the washing tank, the floating and adsorbed film on the film is covered by the pattern after air drying, which is difficult to remove, causing damage to the film.

[0005] Therefore, it is necessary to improve the existing film punching machine to reduce pollution during the film production process to avoid the attachment of pollutants on the film affecting the product quality. Utility model content
