Thermal transfer-printing ink ribbon ink and basis-material recovery method and device

Abstract

The invention discloses a method and equipment thereof for recycling printing ink and base materials of a thermal transferring ribbon. The thermal transferring ribbon comprises a ribbon base film, a printing ink layer coated on one lateral surface of the ribbon base film, and a heat-resisting back layer coated on the other side surface of the ribbon base film. The ribbon base film and the heat-resisting back layer form the base materials. The method for recycling the printing ink and the base materials of the thermal transferring ribbon comprises heating the printing ink layer of the thermal transferring ribbon, and cooling the heat-resisting back layer synchronously to make the printing ink separated from the base material surface. The recycling equipment structure comprises a coil releasing shaft, a heating roller, a glue roller, a cooling roller, a scraper, a material collecting disk and a coil collecting shaft, wherein the heating roller is contacted with the glue roller, the ribbon is arranged between the glue roller and the cooling roller, the cooling roller is pressed on the glue roller, the scraper is arranged on the heating roller, and the material collecting disk is arranged on the lower side of the heating roller. The equipment can instantly separate the base material and the printing ink according to the fact that a material expands upon heating and contracts upon cooling under the condition of quick heating and cooling to recycle the base material and the printing ink respectively, thereby not only reducing environment pollution, but also saving cost.

Description

technical field [0001] The invention relates to a ribbon recovery method and equipment, in particular to a thermal transfer ribbon ink and base material recovery method and equipment. Background technique [0002] Since the 1980s, with the development of office equipment, office automation consumables have become increasingly prominent, and the application fields of thermal transfer ribbons in these consumables have become wider and wider, mainly used in post and telecommunications, railways, supermarkets, factories and banner industries, etc. . With the wide application of thermal transfer ribbons, the output is also increasing year by year, and because thermal transfer ribbons are disposable consumables, a large amount of waste ribbons are produced, and the disposal of waste ribbons has become a problem. Methods such as discarding and burning will pollute the environment. Only recycling the base material (polyester film) and reusing the remaining ink is a good way to save...

AI Technical Summary

Problems solved by technology

However, in this method, because the polyester film of the base material is very thin, using a mechanical method to scrape the ink on the film with a knife, there are many problems in actual super-operation, such as whether the ink can be cleaned up; whether the film will be damaged Cutting; the contact force between the scraper and the film, etc.
