Ink traceability recovery process method based on blockchain

Abstract

The invention relates to an ink traceability recovery process method based on a blockchain. According to the ink traceability recovery process method, a data acquisition unit is used for acquiring a recovery batch number, a production date and time period and a product code of an ink screen printing plate, and a product code and a packaging date of corresponding recovered printing ink, packaging and uploading to the blockchain; the traceability of the printing ink is ensured by adopting a blockchain technology; and meanwhile, the printing ink on the printing ink screen printing plate is softened by the steam nozzle, the printing ink on the printing ink screen printing plate is washed by using a hot water spray head, then the washed and wetted printing ink screen printing plate is baked athigh temperature, the baked steam and washing water with the printing ink are collected, mixed, filtered, extracted and filtered again to obtain finished printing ink. Therefore, the waste of the printing ink is avoided, the recovery rate of the printing ink is extremely high, and online automatic detection of a printing ink tank can be achieved through a cloud server.

Description

technical field [0001] The present invention relates to the field of ink traceability recovery processing based on blockchain, in particular to a blockchain-based ink traceability recovery process method. Background technique [0002] At present, screen printing has become the mainstream of orifice printing due to its easy production method and simple printing equipment, but it has a good reproduction effect. However, after the screen printing is completed, a large amount of ink will remain on the screen printing plate If the ink is not recycled, it will cause a waste of ink, and the main component of the ink contains volatile harmful solvents, which will destroy the ecological environment and endanger people's health. [0003] The traditional recycling method is to gather the recovered screen printing plates together, rinse them directly with a large amount of water, collect the rinse water and then purify the ink to obtain the ink. This method not only consumes a lot of wa...

[0002] At present, screen printing has become the mainstream of orifice printing due to its easy production method and simple printing equipment, but it has a good reproduction effect. However, after the screen printing is completed, a large amount of ink will remain on the screen printing plate If the ink is not recycled, it will cause waste of ink, and the main component of the ink contains volatile harmful solvents, which will damage the ecological environment and endanger people's health

[0003] The traditional recycling method is to gather the recovered screen printing plates together, rinse them directly with a large amount of water, collect the rinse water and then purify the ink to obtain the ink. This method not only consumes a lot of water, but also has a very high ink recovery efficiency. Low, and different quality inks are mixed together, it is difficult to guarantee the quality of the recycled ink, and it is impossible to trace the source of the recycled ink, so that once there is a problem with the recycled ink, it is impossible to find the source of the problem

[0004] Moreover, the finished ink is generally put into the ink tank for sealed storage. However, the ink tank is often damaged, resulting in the leakage of the finished ink, which not only wastes the ink, but also causes damage to the environment.
